LEXUS SAFETY
SYSTEM+ 2.0
A COMPREHENSIVE SUITE OF
ADVANCED TECHNOLOGIES

Lexus Safety System+ 2.01 is designed to help protect drivers, passengers, people in other vehicles on the road,
pedestrians and cyclists from harm. This latest generation of Lexus Safety System+ represents the next milestone in a long
history of creating advancements and innovations in safety that help prevent crashes and protect people.

LEXUS SAFETY SYSTEM+ 2.0 ADDRESSES
THE THREE MOST COMMON ACCIDENT TYPES

FRONTAL COLLISIONS                                                UNINTENDED LANE DEPARTURES                                         NIGHTTIME ACCIDENTS

Under certain conditions, Lexus Safety System+ 2.01 is designed to support driver awareness, decision making and vehicle operation over a wide
range of speeds. Packaged together in an integrated system, Lexus Safety System+ features help address three key areas of accident protection*:
preventing or mitigating frontal collisions2, keeping drivers within their lane3, and enhancing road safety during nighttime driving4. However, drivers
are responsible for their own safety, and must always drive safely, obey traffic speed limits and laws and focus on the road while driving.
Lexus Safety System+ 2.01 builds on the previous Lexus Safety System+ suite and consists of six active safety and driver assistance systems:
• Pre-Collision System2 with Daytime/Low-Light Vehicle and
                                                                                                         • Intelligent High Beams4
  Pedestrian Detection, plus Daytime Bicyclist Detection5
                                                                                                         • Road Sign Assist7
• Dynamic Radar Cruise Control6 with All-Speed Range
                                                                                                         • Lane Tracing Assist8
• Lane Departure Alert3 with Steering Assist
Actual driver assistance system may vary by vehicle – refer to Owner’s Manual to confirm.

PRE-COLLISION SYSTEM
WITH DAYTIME/LOW-LIGHT VEHICLE AND PEDESTRIAN DETECTION, PLUS DAYTIME BICYCLIST DETECTION

Availability:
LS 2019 | ES 2019 | UX 2019

Pre-Collision System2 uses an integrated forward-facing camera and grille-
mounted radar system designed to help mitigate or avoid a frontal collision.
For Lexus Safety System+ 2.01, Pre-Collision System has been enhanced with
the ability to detect a bicyclist in daytime situations, as well as a vehicle and
a pedestrian in both daytime and low-light situations5.

VEHICLE DETECTION
When Pre-Collision System2 determines that the possibility of a frontal
collision with another vehicle is high, it prompts the driver to take evasive
action and brake by using an audible and visual alert. If the driver notices the
hazard and brakes, Pre-Collision System may use Brake Assist9 to provide
additional braking force.

If the driver does not brake in a set time and the system determines that the possibility of a frontal collision with another vehicle is extremely
high, the system may use Automatic Emergency Braking (AEB)10 to automatically apply the brakes, reducing speed to help mitigate the
impact or avoid the collision entirely if possible.

PEDESTRIAN AND BICYCLIST DETECTION
Under certain conditions, if the Pre-Collision System2 determines that
the possibility of a frontal collision with a pedestrian or bicyclist is high5, it
prompts the driver to take evasive action and brake by using an audible and
visual alert. If the driver notices the hazard and brakes, the system may use
Brake Assist9 to provide additional braking force.

If the driver does not brake in a set time and the system determines that the
risk of collision with a pedestrian or bicyclist is extremely high5, the system
may use Automatic Emergency Braking (AEB)10 to automatically apply the
brakes, reducing speed to help mitigate the impact or avoid the collision
entirely if possible.

Refer to a Lexus Owner’s Manual for additional information on Pre-Collision System operation, settings, adjustments, limitations and
precautions.

ALL-SPEED DYNAMIC RADAR CRUISE CONTROL
Availability:
LS 2019 | ES 2019 | UX 2019

Dynamic Radar Cruise Control6 is a high-tech cruise control system that uses
a front grille-mounted radar and a forward-facing camera to detect a vehicle
in front of you and automatically adjust the vehicle's speed to help maintain a
pre-set distance behind a vehicle ahead.

Intended for highways, and similar to “constant speed” cruise control, Dynamic
Radar Cruise Control6 lets drivers maintain a set speed without constant
throttle input from the driver. Dynamic Radar Cruise Control goes a step
further by including a vehicle-to-vehicle distance control system, which adjusts
the vehicle speed to help maintain a pre-set distance from a vehicle ahead.

This means that if the vehicle ahead is detected traveling at a slower speed
than your pre-set speed, Dynamic Radar Cruise Control6 will automatically
slow the vehicle to maintain a pre-set following distance without deactivating cruise control. If Dynamic Radar Cruise Control determines
the vehicle needs to slow down even more, an audible and visual alert occurs and brakes may be applied. When there’s no longer a
preceding vehicle driving slower than your set speed, Dynamic Radar Cruise Control will accelerate back to your set speed.

All models equipped with Lexus Safety System+ 2.01 feature All-Speed Dynamic Radar Cruise Control6, which is designed to allow low-
speed following, speed matching, stopping, and acceleration/deceleration to a preceding vehicle.

Refer to a Lexus Owner’s Manual for additional information on Dynamic Radar Cruise Control operation, settings, adjustments, limitations
and precautions.

                                                                   Minimum Set Speed                       Operation Speed Range

LANE DEPARTURE ALERT
WITH STEERING ASSIST

Availability:
LS 2019 | ES 2019 | UX 2019

Lane Departure Alert3 is designed to use the vehicle's forward-facing camera
to detect lane departure when traveling on relatively straight roads with
clear white or yellow lane markings, as well as certain road edges or
curbs. The system's current operating status is indicated through colored lane
marking illustrations on the vehicle's Multi-Information Display (MID) and
available Head Up Display (HUD). If Lane Departure Alert determines that
the vehicle is starting to unintentionally deviate from its visibly marked lane, the
system alerts the driver with an audible and visual alert and steering wheel
vibration. When this alert occurs, drivers must carefully check the surrounding
road before safely directing the vehicle back to the center of the lane.

STEERING ASSIST
In addition to the alert function, Lexus Safety System+ 2.01 Lane Departure Alert also includes Steering Assist3. When this functionality is
enabled and Lane Departure Alert senses that the vehicle is unintentionally drifting from its lane, the system may automatically make small
corrective steering inputs to help the driver keep the vehicle in its lane.
                                                                                                                                                           3

INTELLIGENT HIGH BEAMS
Availability:
LS 2019 | ES 2019 | UX 2019

Intelligent High Beams4 are a safety system designed to help the driver see more
clearly at night – while reducing glare for other drivers. By using high beams more
frequently, the system may allow earlier detection of pedestrians and obstacles.

When activated, Intelligent High Beams4 are designed to rely on an in-vehicle
camera to help detect the headlights of oncoming vehicles and taillights of
preceding vehicles, then automatically toggle between high and low beams.

Refer to a Lexus Owner’s Manual for additional information on Intelligent
High Beams operation, settings, adjustments, limitations and precautions.

ROAD SIGN ASSIST
Availability:
LS 2019 | ES 2019 | UX 2019

Road Sign Assist7 is designed to read certain traffic signs and display them on the vehicle’s Multi-
Information Display (MID) or available Head Up Display (HUD). Road Sign Assist also aides the
driver in the event a sign is overlooked or missed. While a speed limit sign is displayed, the system notifies
the driver if the vehicle exceeds the displayed speed limit plus a specified threshold value. The driver is
notified by displaying an orange border of the sign in the MID. The system can read Speed Limit, Stop,
Yield, and Do Not Enter signs. When Do Not Enter signs are detected, the driver is notified by flashing
the sign in the multi-information display. The settings can be customized so that a buzzer sounds when
the notification is displayed.

Refer to a Lexus Owner’s Manual for additional information on Road Sign Assist operation, settings,
adjustments, limitations and precautions.

                                                                                                                                                             4

LANE TRACING ASSIST
Availability:
LS 2019 | ES 2019 | UX 2019

Lane Tracing Assist8 is designed to work with Dynamic Radar Cruise
Control6 to keep the vehicle centered in its visibly marked lane and
preemptively avoid unintented lane departures.

Lane Tracing Assist8 uses a forward-facing camera to monitor lane markings
– as well as the path of the vehicle ahead, if needed – and is designed to
automatically make constant steering inputs to help keep the vehicle
centered in its lane. Lane Tracing Assist requires the driver's hands to remain
on the steering wheel.

Refer to a Lexus Owner’s Manual for additional information on Lane Tracing
Assist operation, settings, adjustments, limitations and precautions.

PRECAUTIONS: PRE-COLLISION SYSTEM
Pre-Collision System2 is premised on safe driving by the driver. It is not a system that will avoid collisions under all conditions. Do not depend on the system or use it in place of
emergency brake operation. Pre-Collision System operation is dependent on the front grille-mounted millimeter-wave radar and in-vehicle camera's ability to detect and see clearly
a preceding vehicle or pedestrian3 on relatively straight roadways, as well as the visibility/detectability of the preceding vehicle/pedestrian itself. Pre-Collision System may not operate
if it does not recognize a preceding vehicle or pedestrian. Pre-Collision System is not designed to detect animals or other objects. Situations such as a fogged, dirty, broken or tinted
windshield or rain, snow, ice or sticker-covered windshield blocking the camera or laser may affect Pre-Collision System operation. Intense light from the front or inclement weather
obstructing camera visibility or laser detection, or sharp curves in the road, may affect Pre-Collision System operation. Also, changes to the vehicle's height or angle from load, towing,
suspension or tire modifications/chains or lift kits may affect Pre-Collision System operation. Furthermore, if a preceding vehicle is not correctly recognized, unneeded driver alerts or
automatic braking may occur, so drivers need to pay continuous attention to the surrounding conditions, the direction of travel and vehicle's location on the road. Ultimately, drivers are
responsible for their own safe driving, steering, braking, the vehicle speed and operation, and distance to a preceding vehicle at all times. (NOTE: Vehicles equipped with Lexus Safety
System+ 2.01 may also detect a bicyclist3, in addition to a vehicle and a pedestrian.)

Pre-Collision System2 may not recognize a vehicle or a pedestrian in the following conditions and environments:
 When vehicle angle/stance is changed, for example if the vehicle is lifted or lowered, is
                                                                                                 If the rear-most surface of the preceding vehicle is small, low or irregularly high
 towing, or is loaded down with weight

 When there is a problem with the vehicle or if it is modified                                   If the camera and radar is misaligned or being blocked (by a wiper blade, etc.)

PRECAUTIONS: DYNAMIC RADAR CRUISE CONTROL
Dynamic Radar Cruise Control6 is a system designed for driving on expressways and highways. Dynamic Radar Cruise Control is not designed for, and should not be used in traffic
conditions that are encountered when driving on roads other than expressways and highways. Attentive and responsible driving is necessary even when Dynamic Radar Cruise Control
is active, otherwise an accident may occur. Dynamic Radar Cruise Control operation is dependent on the millimeter-wave radar and in-vehicle camera's ability to detect a preceding
vehicle, as well as the detectability of the preceding vehicle itself. While driving, drivers will need to continually pay attention to the distance between vehicles, respect the leading vehicle and
surroundings, and decelerate or accelerate to ensure distance between their vehicle and the preceding or following vehicles is safe. Situations such as a dirt, rain, snow, film, ice or sticker-
covered/broken front Lexus emblem blocking the radar all may affect Dynamic Radar Cruise Control operation.

In the following conditions, Dynamic Radar Cruise Control6 may lead to an unexpected accident, so do not use the system:
 When vehicle angle/stance is changed, for example if the vehicle is lifted or lowered, is
                                                                                                      When driving in inclement weather such as rain, fog, snow or a dust storm

PRECAUTIONS: LANE DEPARTURE ALERT
Lane Departure Alert3 operation is dependent on the in-vehicle camera's ability to see clearly and detect visible lane markers on relatively straight roadways, as well as the visibility
of the lane markers themselves. Lane Departure Alert does not operate if it cannot recognize visible lane markers. Situations such as a fogged, dirty, broken, or tinted windshield or
rain, snow, ice or sticker-covered windshield blocking the camera may affect Lane Departure Alert operation. Also, changes to the vehicle's height or angle from hauling heavy loads,
towing, suspension lowering/lifting, or tire modifications/chains may affect Lane Departure Alert operation. Furthermore, if lane markers cannot be correctly recognized, there are
cases where unneeded driver alerts may occur, so the driver needs to pay continuous attention to the surrounding conditions, the direction of travel and vehicle's location on the road.
Ultimately drivers are responsible for steering input and vehicle operation at all times. (NOTE: Vehicles equipped with Lexus Safety System+ 2.01 may also detect curbs and road
edges, in addition to lane markers.)

Lane Departure Alert3 may not operate as designed under the following conditions:
 When vehicle angle/stance is changed, for example if the vehicle is lifted or lowered, is      When approaching objects on the roadside that may be misunderstood as a white line,
 towing, or is loaded down with weight                                                          such as a guard rail, curb, reflection pole, etc.

 When there is a problem with the vehicle or if it is modified                                  When driving at a branching or merging road location

 When driving in inclement weather such as rain, fog, snow, dust storm, etc. blocking           When driving around locations with sharp curves or undulations or for a period of time

PRECAUTIONS: INTELLIGENT HIGH BEAMS
Intelligent High Beams4 operation is dependent on the in-vehicle camera's ability to see clearly and detect preceding headlights or taillights, as well as the visibility of the preceding
headlights or taillights themselves. Situations such as a fogged, dirty, broken, or tinted windshield or rain, snow, ice or sticker-covered windshield blocking the camera may affect
Intelligent High Beams operation. Drivers are responsible for paying attention to their surroundings and directly confirming the safety of their surroundings by turning high beams ON
and OFF manually as needed.

In the following conditions, the system many not be able to accurately detect surrounding vehicles and light:

 When driving in inclement weather such as rain, fog, snow or a dust storm                        When driving on a road with frequent curves or when there is a sharp curve

PRECAUTIONS: LANE TRACING ASSIST
Lane Tracing Assist8 is a system that operates only when All-Speed Dynamic Radar Cruise Control6 and Lane Departure Alert3 are activated. The Lane Tracing Assist system is
designed for driving on expressways and highways. Lane Tracing Assist is not designed for, and should not be used in traffic conditions that are encountered when driving on roads
other than expressways and highways. Attentive and responsible driving is necessary even when Lane Tracing Assist is active, otherwise an accident may occur. Lane Tracing Assist
operation is dependent on the vehicles millimeter-wave radar's ability to detect a preceding vehicle as well as the in-vehicle camera's ability to see clearly and detect visible lane
markers on relatively straight roadways, as well as the visibility of the lane markers themselves. Lane Tracing Assist does not operate if it cannot recognize visible marked lanes or a
preceding vehicle. While driving, drivers need to continually pay attention to the distance between vehicles and surroundings, and decelerate or accelerate to ensure a safe distance
between their vehicle and preceding/following vehicles. Situations such as a fogged, dirty, broken, or tinted windshield or rain, snow, ice or sticker-covered windshield or anything
blocking the Lexus emblem radar sensor and/or the in-vehicle camera may affect Lane Tracing Assist operation. Also, changes to the vehicle's height or angle due to suspension or tire
modifications/chains may affect Lane Tracing Assist operation. Furthermore, if lane markers cannot be correctly recognized, there are cases where unneeded driver alerts may occur,
so drivers need to pay continuous attention to the surrounding conditions, the direction of travel, and the vehicle's location on the road. Ultimately, drivers are responsible for steering
input and vehicle operation at all times.

In the following conditions, Lane Tracing Assist8 may not operate as designed:
 When vehicle angle/stance is changed, for example if the vehicle is lifted or lowered, is       When the leading vehicle has a very small rear surface area, such as a vehicle pulling
 towing, or is loaded down with weight                                                           an empty trailer
