WARNING

■

Caution for use while driving

●

When operating the multi-information display while driving, pay extra attention to the
safety of the area around the vehicle.

●

Do not look continuously at the multi-information display while driving as you may fail
to see pedestrians, objects on the road, etc. ahead of the vehicle.

■

The information display at low temperatures

Allow the interior of the vehicle to warm up before using the liquid crystal information
display. At extremely low temperatures, the information display monitor may respond
slowly, and display changes may be delayed.
For example, there is a lag between the driver’s shifting and the new gear number
appearing on the display. This lag could cause the driver to downshift again, causing rapid
and excessive engine braking and possibly an accident resulting in death or injury.

■

Cautions during setting up the display

As the engine needs to be running during setting up the 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 battery discharge, ensure that the engine is running while setting up the
display features.

Features of the safe driving support functions

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.

■

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.

■

EPS (Electric Power Steering)

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

6-1. Features of the safe driving support functions

334

■

Dynamic Torque Control AWD system

Automatically controls the driving force distribution to the front and rear wheels
according to various running conditions including normal driving, during corner-
ing, 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/Trailer Sway Control systems are operating

The slip indicator light will flash while the
TRAC/VSC/Trailer Sway Control systems are oper-
ating.

■

Disabling the TRAC system

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

the engine to the wheels. Pressing [

] to turn the system off may make it easier for

you to rock the vehicle in order to free it.

To turn the TRAC system off, quickly press and release[

The "Traction Control Turned OFF"will be shown on the multi-information display. Press

TRAC and hill-start assist control systems

●

A sound may be heard from the engine compartment when the brake pedal is
depressed repeatedly, when the engine is started or just after the vehicle begins to
move. This sound does not indicate that a malfunction has occurred in any of these
systems.

●

Any of the following conditions may occur when the above systems are operating.
None of these indicates that a malfunction has occurred.

After turning the TRAC, Trailer Sway Control and VSC systems off, the systems will be
automatically re-enabled in the following situations:

●

When the engine switch is turned off

●

If only the TRAC system is turned off, the TRAC will turn on when vehicle speed
increases
If both the TRAC and VSC systems are turned off, automatic re-enabling will not

●

Do not overly rely on hill-start assist control. Hill-start assist control may not operate
effectively on steep inclines and roads covered with ice.

accident. Exercise particular care when the indicator light flashes.

■

Be especially careful and drive at a speed appropriate to the road conditions.
As these are the systems to help ensure vehicle stability and driving force, do not turn the
TRAC/VSC/Trailer Sway Control systems off unless necessary.
Trailer Sway Control is part of the VSC system and will not operate if VSC is turned off or
experiences a malfunction.

■

Replacing tires

Make sure that all tires are of the specified size, brand, tread pattern and total load
capacity. In addition, make sure that the tires are inflated to the recommended tire
inflation pressure level.
The ABS, TRAC and VSC systems will not function correctly if different tires are installed
on the vehicle.
Contact your Lexus dealer for further information when replacing tires or wheels.

■

Handling of tires and the suspension

Using tires with any kind of problem or modifying the suspension will affect the driving
assist systems, and may cause a system to malfunction.

■

Trailer Sway Control precaution

The Trailer Sway Control system is not able to reduce trailer sway in all situations.
Depending on many factors such as the conditions of the vehicle, trailer, road surface and
driving environment, the Trailer Sway Control system may not be effective. Refer to your
trailer owner's manual for information on how to tow your trailer properly.

■

If trailer sway occurs

Observe the following precautions. Failing to do so may cause death or serious injury.

●

Firmly grip the steering wheel. Steer straight ahead. Do not try to control trailer sway
by turning the steering wheel.

●

Begin releasing the accelerator pedal immediately but very gradually to reduce speed.

reduce the possibility of further damage due to a secondary collision, however, that effect
changes according to various conditions. Overly relying on the system may result in
death or serious injury.
