4-5. Using the driving support systems

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.

◆

Secondary Collision Brake (if equipped)

When the airbag sensor detects a collision, the brakes and brake
lights are automatically controlled to reduce the vehicle speed and
that helps reduce the possibility of further damage due to a second-
ary collision

◆

TRAC

 

(Traction Control)

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

◆

Hill-start assist control

Helps to reduce the backward movement of the vehicle when start-
ing on an uphill

Driving assist systems

To keep driving safety and performance, the following systems
operate automatically 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 vehi-
cle.

EPS (Electric Power Steering) 

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

The slip indicator light will flash
while the TRAC/VSC systems are
operating.

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 

.

“Traction Control Turned Off” will
be shown on the multi-information
display.

 again to turn the sys-

tem back on.

Turning off both TRAC and VSC systems

To turn the TRAC and VSC systems off, press and hold 

 for more than 3

seconds while the vehicle is stopped.
The VSC OFF indicator light will come on and the “Traction Control Turned
Off” will be shown on the multi-information display

.

Press 

 again to turn the systems back on.

*

: On vehicles with pre-collision system, pre-collision brake assist and pre-

collision braking will also be disabled. The pre-collision system warning
light will come on and the message will be shown on the multi-information
display. (

→P. 252)

■

When the message is displayed on the multi-information display show-

ing that TRAC has been disabled even if 

 has not been pressed

TRAC cannot be operated. Contact your Toyota dealer.

■

Operating conditions of hill-start assist control
When the following four conditions are met, the hill-start assist control will
operate:

●

The shift lever is in a position other than P or N (when starting off forward/
backward on an upward incline)

●

The vehicle is stopped

●

The accelerator pedal is not depressed

●

The parking brake is not engaged

■

Automatic system cancelation of hill-start assist control
The hill-start assist control will turn off in any of the following situations:

●

The shift lever is shifted to P or N

●

The accelerator pedal is depressed

●

The parking brake is engaged

●

2 seconds at maximum elapsed after the brake pedal is released

Sounds and vibrations caused by the ABS, brake assist, VSC, 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. 
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard also after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.

■

EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may be
heard. This does not indicate a malfunction.

■

Automatic reactivation of TRAC and VSC systems
After turning the TRAC and VSC systems off, the systems will be automati-
cally 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 occur when vehicle speed increases.

■

Secondary Collision Brake operating conditions
The vehicle speed is approximately 6 mph (10 km/h) or more and the airbag
sensor detects a collision. (The Secondary Collision Brake will not operate
when the vehicle speed is below approximately 6 mph [10km/h].)

■

Secondary Collision Brake automatic cancellation
The Secondary Collision Brake is automatically canceled in the following situ-
ations:

●

The vehicle speed drops below approximately 6 mph (10 km/h)

●

A certain amount of time elapses during operation

●

The accelerator pedal is depressed a large amount

■

Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from
overheating when there is frequent steering input over an extended period of
time. The steering wheel may feel heavy as a result. 
Should this occur, refrain from excessive steering input or stop the vehicle
and turn the engine off. The EPS system should return to normal within 10
minutes.
