Do not attempt a steep descent if All Surface Progress Control (ASPC) is not enabled, or if the message center displays warning messages.


The driver must maintain full control of the steering and brakes at all times.

The ASPC button is located on the center console.

Press and release the button to enable ASPC. The button's LED lamp illuminates and the message center displays a confirmation message, prompting to set the target speed for the vehicle. The instrument panel also illuminates the ASPC amber warning lamp to confirm. See PROGRESS CONTROL SYSTEM (AMBER).

ASPC can be enabled when the vehicle is stationary and when the vehicle is moving. When the vehicle is stationary, apply the brake pedal to maintain control of the vehicle.


ASPC cannot be enabled if the park assist feature is currently enabled. See SELECTING PARK ASSIST.


The vehicle's cruise control, speed limiter, and auto stop/start systems are disabled during ASPC operation.

The ASPC enabled status is retained for up to 6 hours after the ignition is switched off. After this time, it has to be reselected, if ASPC is still required when the ignition is switched on.

Press and release the ASPC button again to disable the system. The button's LED lamp and the ASPC warning lamp extinguish to confirm. The message center also displays an ASPC off confirmation message.

ASPC operation is influenced by the current driving mode selection. For example, the rain/ice/snow mode requires gradual ASPC acceleration to help gain available wheel traction. The normal mode allows increased ASPC acceleration to help improve vehicle progress.

When enabled, ASPC defaults to descent control mode, i.e., the system only limits the vehicle's downhill speed, using the brakes.

When ASPC enters in to descent control mode the message center displays the ASPC Descent Braking Only confirmation message.

Use the ASPC descent control mode when traveling down a steep descent:

  • Select the required position for the gear selector.

  • Release the vehicle's brakes to allow gravity to make the vehicle progress, up to the minimum feature speed of 2.2 mph (3.6 km/h).

  • ASPC maintains this speed, unless ASPC detects the use of the accelerator or brake pedals, or the SET+ button on the steering wheel controls. See PROGRESS CONTROL SYSTEM SETTINGS.


    Descent control mode resumes when the accelerator pedal or the brake pedal, is released and the steering wheel's SET+ button is not used.


    If the steering wheel's SET+ button is used, ASPC enters in to full function mode.

When ASPC enters into full function mode, the message center displays the ASPC Speed Set confirmation message.


The driver’s seat belt must be buckled and all of the doors must be completely closed to enable ASPC to enter into full function mode. If these conditions are not met, the message center displays a message.

Full function mode controls the vehicle's speed via the use of both the brakes and engine torque.

Full function mode should be used for all other maneuvers that require the vehicle to gain and make progress. For example, making an ascent, pulling away from a standstill, and driving on unstable and slippery driving surfaces.


When the vehicle is stationary, press and hold the brake pedal while using the SET+ button.


When the vehicle is moving, the SET+ button can be used without applying the brake pedal.


ASPC defaults to descent control mode with the gear selector in the Neutral (N) position. In this event, the message center displays a message.


If the vehicle's brakes are firmly applied, during operation of ASPC, the system exits full function mode and reverts to descent control mode.


Light and gentle application of the brake pedal, during ASPC operation, lowers the vehicle's target speed. When the brake pedal is fully released, ASPC maintains the speed at which the brake pedal was released.


The driver can override ASPC operation at any time, using the brake pedal or the accelerator pedal. The message center displays an ASPC override message.


If the vehicle's speed exceeds 19 mph (30 km/h), ASPC operation is suspended. ASPC is then in standby mode until the vehicle's speed is less than 19 mph (30 km/h).


If the vehicle's speed exceeds 50 mph (80 km/h), ASPC is disabled. The message center displays an ASPC off message. If required, ASPC has to be switched on again.

When ASPC is enabled and the brake pedal is fully released, the system helps to provide controlled and progressive assistance for the vehicle to:

  • Pull away from a standstill, in a forward or reverse direction on level ground, and uphill or downhill.

  • Perform low speed maneuvering in a forward or reverse direction.

  • Make progress and maintain a selected target (set) speed, up to a maximum of 19 mph (30 km/h).

In the event that the vehicle's brake temperatures exceed the normal operating limits, the message center displays a warning message. In this event, ASPC fades out and becomes temporarily inactive. When the brakes return to normal operating temperatures, the message extinguishes and ASPC resumes normal operation.

If an ASPC fault is detected, the message center displays an ASPC not available message when the ASPC button is pressed. In this event consult a retailer/authorized repairer.
