Driving assist systems

To help enhance 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 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, while 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.

■ TRAC (Traction Control)

Maintains drive power and prevents the rear wheels (2WD models) or four wheels (4WD models) from spinning when starting the vehicle or accelerating on slippery roads.

Hill-start assist control (if equipped)

Helps prevent the vehicle from rolling backwards when starting on an incline or slippery slope. It operates for approximately 5 seconds at maximum.

2-4. Using other driving systems

When the VSC/TRAC/hill-start assist control systems are operating

If the vehicle is in danger of slipping, the rear wheels (2WD models) or four wheels (4WD models) spin, the vehicle starts to roll backwards when starting on an incline, this indicator flashes to indicate that the VSC/

TRAC/hill-start assist control systems have been engaged.

A buzzer (intermittent) sounds to indicate that VSC is operating.

The stop lights and high mounted stoplight turn on when the hillstart assist control system is operating.

To disable TRAC and/or VSC

If the vehicle gets stuck in fresh snow or mud, TRAC and VSC may reduce power from the engine to the wheels. You may need to turn the system off to enable you to rock the vehicle in order to free it.

Turning off TRAC (2WD models and 2WD mode on 4WD models)

Quickly push and release the

VSC OFF switch to turn off

TRAC.

The AUTO LSD indicator light should come on.

Push the switch again to turn the system back on.

2-4. Using other driving systems

Turning off TRAC and VSC

Press and hold the VSC OFF switch for more than 3 seconds while the vehicle is stopped to turn off both TRAC and VSC.

The VSC OFF indicator light should come on.

Push the switch again to turn both systems back on.

■ Automatic reactivation of TRAC and VSC

Turning the engine switch off after turning off the TRAC and VSC systems will automatically re-enable them.

■ Automatic TRAC reactivation (AUTO LSD mode)

With AUTO LSD mode, VSC OFF and AUTO LSD indicator lights turn on.

The TRAC system will turn on when the vehicle speed increases.

■ Automatic TRAC and VSC reactivation

If the TRAC and VSC systems are turned off, the systems will not turn on even when vehicle speed increases.

■ Sounds and vibrations caused by the ABS, TRAC, VSC, brake assist and hill-start assist control system

● A sound may be heard from the engine compartment 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 after the vehicle comes to a stop.

• The brake pedal may pulsate slightly when the ABS is activated.

• The brake pedal may move down slightly after the ABS is activated.

● The brake pedal is not depressed.

■ Hill-start assist control will not operate when (if equipped)

● The shift lever is in the P, R or N positions.

2-4. Using other driving systems

CAUTION

■ The ABS does not operate effectively when

● The limits of the gripping performance have been exceeded.

● The vehicle hydroplanes while driving at high speed on the wet or slick road.

■ Stopping distance when the ABS is operating will exceed that of normal conditions

The ABS is not designed to shorten the vehicle’s stopping distance. Always maintain a safe distance from the vehicle in front of you in the following situations.

● When driving on dirt, gravel or snow-covered roads

● When driving with tire chains

● When driving over bumps in the road

● When driving over roads with potholes or roads with uneven roads

■ When VSC is activated

The slip indicator flashes and a warning buzzer sounds. Always drive carefully. Reckless driving may cause an accident. Exercise particular care when the indicator flashes and a buzzer sounds.

■ TRAC may not operate effectively when

Directional control and power may not be achievable while driving on slippery road surfaces, even if TRAC is operating.

Do not drive the vehicle in conditions where stability and power may be lost.

■ If the hill-start assist control does not operate effectively

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

■ Replacing tires

Make sure that all tires are of the same size, brand, tread pattern and total load capacity. In addition, make sure that the tires are inflated to the appropriate tire pressure level.

The ABS and VSC will not function correctly if different tires are fitted on the vehicle.

Contact your Toyota dealer for further information when replacing tires or wheels.
