When driving � Using other driving systems
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.

  •  Multi Terrain 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, or in offroad conditions (such as rough roads, sand and mud).

  •  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.

  •  Active TRAC (Traction Control)

Helps to maintain drive power and prevent the 4 wheels from spinning when starting the vehicle or accelerating on slippery roads.

  •  Hill-start assist control

Helps to prevent the vehicle from rolling backwards when starting on an incline or slippery slope.

  •  KDSS (Kinetic Dynamic Suspension System)

KDSS helps to ensure ride comfort and handling response by using a hydraulic control system to control the suspension stabilizer bars in response to road surface and driving conditions during cornering or offroad driving.

  •  VGRS (Variable Gear Ratio Steering) (if equipped)

Helps to adjust the wheel turning angle in accordance with the vehicle speed and steering wheel movement.

  •  PCS (Pre-Collision System) (if equipped)
  • Trailer Sway Control

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

Trailer Sway Control is part of the VSC system and will not operate if VSC turned off or experiences a malfunction.

When the VSC/Trailer Sway Control/Active TRAC/hill-start assist control systems are operating

The slip indicator light flashes to

The slip indicator light flashes to indicate that the VSC/Trailer Sway Control/Active TRAC/hillstart assist control systems have been engaged.

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

To disable Active TRAC and/or VSC and Trailer Sway Control

If the vehicle gets stuck in fresh snow or mud, Active TRAC, VSC and Trailer Sway Control 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 Active TRAC

Push the button again to turn the system back on.

  • Turning off Active TRAC, VSC and Trailer Sway Control

Push and hold the button for

Push and hold the button for more than 3 seconds while the vehicle is stopped to turn off Active TRAC, VSC and Trailer Sway Control.

The VSC OFF indicator light will come on and the �TRAC OFF� will be shown on the multi-information display.

Push the button again to turn the system back on.

  • When the message is displayed on the multi-information display showing that TRAC has been disabled even if the VSC OFF switch has not been pressed

Active TRAC, hill-start assist control, Crawl Control cannot be operated.

Contact your Toyota dealer.

  • Automatic reactivation of Active TRAC, VSC and Trailer Sway Control

Turning the �ENGINE START STOP� switch off after turning off the Active TRAC and VSC systems will automatically re-enable them.

  • Automatic Active TRAC reactivation

If only the Active TRAC system is turned off, the Active TRAC system will turn on when vehicle speed increases.

  • Automatic Active TRAC, VSC and Trailer Sway Control reactivation

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

  • If the brake system overheats

The brake system may overheat. In this case, a buzzer will sound, and the �TRAC OFF� will be displayed on the multi-information display, and Active TRAC and hill-start assist control will be temporarily inoperable. In this event, stop the vehicle immediately in a safe place, and allow the brake system to cool down sufficiently until the �TRAC OFF� on the multi-information display go off. (There is no problem with continuing normal driving.)

Sounds and vibrations caused by the Multi Terrain ABS, brake assist, Active TRAC, VSC, Trailer Sway Control, hill-start assist control and VGRS

  • 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 after the Multi Terrain ABS is activated.
  •  The brake pedal may move down slightly after the Multi Terrain ABS is activated.
  • Hill-start assist control is operational when
  • The shift lever is in �D� or �S�.
  • The brake pedal is not depressed.
  • VGRS is disabled in the following situations
  • During stopping or the steering wheel has been moved for a long time while driving at lower speeds.
  • After the engine is restarted at less than -22�F (-30�C).
  • If you disconnect the battery with the steering wheel turned, the center position of the steering wheel could be slightly and temporary hanged. To initialize the VGRS, drive for a short while.
CAUTION

Any of the following conditions may result in an accident which could cause death or serious injury:

  • The Multi Terrain ABS does not operate effectively when
  • The limits of tire gripping performance have been exceeded (such as excessively worn tires on a snow covered road).
  • The vehicle hydroplanes while driving at high speed on the wet or slick road.
  • Stopping distance when the Multi Terrain ABS is operating may exceed that of normal conditions

The Multi Terrain ABS is not designed to shorten the vehicle�s stopping distance.

Always maintain a safe distance from the vehicle in front of you, especially 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 uneven roads
  • Active TRAC may not operate effectively when

Directional control and power may not be achievable while driving on slippery road surfaces, even if the Active 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.

  • When Active TRAC, VSC and Trailer Sway Control are off

Be especially careful and drive at a speed appropriate to the road conditions.

As there are systems to ensure vehicle stability and driving force, do not turn off Active TRAC, VSC and Trailer Sway Control unless necessary.

CAUTION
  • When the VSC and Trailer Sway Control are activated

The slip indicator light flashes. Always drive carefully.

Reckless driving may cause an accident. Exercise particular care when the indicator light flashes.

  • 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 specified tire pressure level.

The Multi Terrain ABS, Active TRAC, VSC and Trailer Sway Control will not function correctly if different tires are fitted on the vehicle.

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

  • Handling of tires and suspension

Using tires with any kind of problem or modifying the suspension will affect the driving assist systems, and may cause the 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 swaying by turning the steering wheel.

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

Do not increase speed. Do not apply vehicle brakes.

If you make no extreme correction with the steering or brakes, your vehicle and trailer should stabilize.

NOTICE
  • KDSS

In the following situations, there is the possibility that a system malfunction has occurred, and drive comfort and the vehicle�s ability to travel on poor road surfaces may be reduced. Take the vehicle to your Toyota dealer immediately.

  • When turning a corner, the vehicle�s body seems to roll further than normal.
  • If after the vehicle has been left in a slanted position for a long time, for example with the wheels of one side parked on a curb, the vehicle does not return to level when driving (the vehicle remains slanted to one side after returning the vehicle to level ground).
