Changing settings for the head-up display

WARNING

●

Check that the position and brightness of the head-up display image does not inter-
fere with safe driving.
Incorrect adjustment of the image’s position or brightness may obstruct the driver’s
view and lead to an accident, resulting in death or serious injury.

As the hybrid system needs to be operating while changing the settings of the head-up
display, ensure that the vehicle is parked in a place with adequate ventilation. In a
closed area such as a garage, exhaust gases including harmful carbon monoxide
(CO) may collect and enter the vehicle. This may lead to death or a serious health
hazard.

NOTICE

To prevent 12-volt battery discharge, ensure that the hybrid system is operating while the
changing the settings of the head-up display.

Lexus Safety System + 3

Lexus Safety System + 3 consists of the driving assist systems and contributes to a
safe and comfortable driving experience.

WARNING

■

Lexus Safety System + 3

Lexus Safety System + 3 operates under the assumption that the driver will drive safely,
and is designed to help reduce the impact to the occupants in a collision and assist the
driver under normal driving conditions.
As there is a limit to the degree of recognition accuracy and control performance that
this system can provide, do not overly rely on this system. The driver is solely responsible
for paying attention to the vehicle’s surroundings and driving safely.

■

For safe use

●

Do not overly rely on this system. The driver is solely responsible for paying attention
to the vehicle’s surroundings and driving safely. This system may not operate in all
situations and provided assistance is limited. Over-reliance on this system to drive the
vehicle safely may lead to an accident resulting in death or serious injury.

●

Do not attempt to test the operation of the system, as it may not operate properly,
possibly leading to an accident.

●

If attention is necessary while performing driving operations or a system malfunction
occurs, a warning message or warning buzzer will be operated. If a warning message
is displayed on the display, follow the instructions displayed.

●

Depending on external noise, the volume of the audio system, etc. it may be difficult to
hear the warning buzzer. Also, depending on the road conditions, it may be difficult to
recognize the operation of the system.

■

When it is necessary to disable the system

In the following situations, make sure to disable the system.
Failure to do so may lead to the system not operating properly, possibly leading to an
accident resulting in death or serious injury.

●

When the vehicle is tilted due to being overloaded or having a flat tire

●

When driving at extremely high speeds

●

When towing another vehicle

●

When the vehicle is being transported by a truck, ship, train, etc.

●

When the vehicle is raised on a lift and the tires are allowed to rotate freely

●

When inspecting the vehicle using a drum tester such as a chassis dynamometer or
speedometer tester, or when using an on vehicle wheel balancer

●

When the vehicle is driven in a sporty manner or off-road

Driving assist systems

To keep driving safety and performance, the following systems operate automat-
ically in response to various driving situations. Be aware, however, that these
systems are supplementary and should not be relied upon too heavily when
operating the vehicle.

■

ECB (Electronically Controlled Brake System)

The electronically controlled system generates braking force corresponding to the
brake operation.

■

ABS (Anti-lock Brake System)

Helps to prevent wheel lock when the brakes are applied suddenly, or if the brakes
are applied while driving on a slippery road surface.

■

Brake assist

Generates an increased level of braking force after the brake pedal is depressed
when the system detects a panic stop situation.

■

VSC (Vehicle Stability Control)

Helps the driver to control skidding when swerving suddenly or turning on slippery
road surfaces.

■

Enhanced VSC (Enhanced Vehicle Stability Control)

Provides cooperative control of the ABS, TRAC, VSC and EPS.
Helps to maintain directional stability when swerving on slippery road surfaces by
controlling steering performance.

■

Trailer Sway Control

Helps the driver to control trailer sway by selectively applying brake pressure for
individual wheels and reducing driving torque when trailer sway is detected.

■

TRAC (Traction Control)

Helps to maintain drive power and prevent the drive wheels from spinning when
starting the vehicle or accelerating on slippery roads

■

Active Cornering Assist (ACA)

Helps to prevent the vehicle from drifting to the outer side by performing inner
wheel brake control when attempting to accelerate while turning.

■

Hill-start assist control

Helps to reduce the backward movement of the vehicle when starting on an uphill.

6-1. Features of the safe driving support functions

379

Driving suppor

t s

ystem

■

EPS (Electric Power Steering)

Employs an electric motor to reduce the amount of effort needed to turn the
steering wheel.

■

E-Four (Electronic On-Demand AWD system)

Automatically controls the drive system such as to front-wheel drive or AWD (all
wheel drive) according to various running conditions including normal driving,
during cornering, on a uphill, when starting off, during acceleration, on a slippery
roads due to snow or rain, thus contributing to stable operability and driving
stability.

■

Adaptive Variable Suspension System

By independently controlling the damping force of the shock absorbers for each of
the 4 wheels according to the road and driving conditions, this system helps riding
comfort with superior vehicle stability, and helps good vehicle posture.
Also, the damping force changes depending on the selected driving mode.

■

The Secondary Collision Brake

When the SRS airbag sensor detects a collision and the system operates, the
brakes and brake lights are automatically controlled to reduce the vehicle speed
and help reduce the possibility of further damage due to a secondary collision.

INFORMATION

■

When the TRAC/VSC/ABS/Trailer Sway Control systems are operating

The slip indicator light will flash while the
TRAC/VSC/ABS/Trailer Sway Control systems are
operating.

■

Disabling the TRAC system

If the vehicle gets stuck in mud, dirt or snow, the TRAC system may reduce power from

the hybrid system to the wheels. Pressing [

] to turn the system off may make it

easier for you to rock the vehicle in order to free it.
