Toyota Grand Highlander (AS10): Multi-terrain Select (AWD models)

Multi-terrain Select is designed to control AWD, brake and driving force systems in accordance with the road condition.

Use the system when driving over muddy, sandy or rough road surfaces.

Control in each mode

Select a mode that is appropriate for the road condition.

■ Mud & Sand mode

Suitable for driving on roads with increased driving resistance in which tires could become stuck, such as sandy roads, muddy roads, etc.

Suitable for driving on bumpy roads, such as on unpaved forest roads.

■ Normal mode

Suitable for normal driving. Use Normal mode when not driving off-road.

3. Switches to Normal mode

Dial type

■Multi-terrain Select

• Multi-terrain Select is intended for use when driving on rough roads.

  Drive in Normal mode during normal driving.

• The Mud & Sand and Rock & Dirt modes control the vehicle so that it can maximize the drive force and improve the drive force on rough roads. As a result, fuel efficiency may diminish when compared to driving in Normal mode.

■When Multi-terrain Select brake control is operating

• The slip indicator flashes when Multi-terrain Select brake control is operating.

■AWD control for Mud & Sand and Rock & Dirt modes

If the vehicle speed exceeds the speeds listed below, the same level of AWD control for Normal mode is performed, even if Mud & Sand or Rock & Dirt mode is selected.

• Mud & Sand mode: Vehicle speed is approximately 25mph (40 km/h) or more
• Rock & Dirt mode: Vehicle speed is approximately 16mph (25 km/h) or more

If the vehicle speed drops below the above speeds, the system automatically returns to the AWD control for each mode.

■When "Traction Control Turned OFF" is displayed on the multi-information display

Multi-terrain Select brake control is temporarily stopped due to overheat of the brakes.

Stop the vehicle in a safe location as soon as possible and wait until the message disappears from the multi-information display.

In the following situations, the system switches to Normal mode automatically:

• When the driving mode is changed
• When the engine switch is turned off
