USING ALL SURFACE PROGRESS CONTROL (ASPC)

WARNING

Do not attempt a steep descent if the All Surface Progress Control (ASPC) system is not enabled, or if the instrument panel displays warning messages. Doing so may potentially result in damage to the vehicle or personal injury.

WARNING

The driver must maintain full control of the steering and brakes at all times. Failure to do so may potentially result in damage to the vehicle or personal injury.

NOTES

The ASPC system cannot be enabled if the park assist feature is currently enabled.

NOTES

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

The ASPC button is located on the center console. Press and release the button to enable the ASPC system. The button's LED lamp illuminates and the instrument panel displays a message, prompting to set the speed for the vehicle. The instrument panel also illuminates the amber ASPC warning lamp to confirm selection. See ALL SURFACE PROGRESS CONTROL (ASPC) (AMBER).

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

NOTES

The driver can override ASPC operation, at any time, by sing the brake pedal or the accelerator pedal. The instrument panel displays an ASPC override message.

The ASPC system 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.

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

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

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

When the ASPC system enters descent control mode, the instrument panel displays a confirmation message indicating that ASPC will only control the vehicle's descent speed.

Use the ASPC system's descent control mode when traveling down a steep descent.

Operate as follows:

  1. Select the correct driving mode for the current driving conditions. See DRIVING MODES OPERATION.

  2. Select the required position for the gear selector.

  3. Release the vehicle's brakes to allow gravity to make the vehicle progress up to the default speed for descent control mode. The currently selected driving mode determines the default speed for descent control mode. The default speed varies from a minimum of 2.2 mph (3.5 km/h) and up to a maximum of 7.5 mph (12 km/h).

  4. The ASPC system maintains the default speed for descent control mode. The ASPC system exits descent control mode if it detects the use of the accelerator pedal or the steering wheel's SET+ button. See ALL SURFACE PROGRESS CONTROL (ASPC) SETTINGS.

    NOTES

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

    NOTES

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

When the ASPC system enters full function mode, the instrument panel displays a prompt message to select the required speed.

NOTES

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

NOTES

If the low friction launch feature is currently enabled, it is disabled when the ASPC system enters full function mode.

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

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

The ASPC system defaults to descent control mode and the instrument panel displays a message, in the event that:

  • The transmission is engaged in Neutral (N) or Park (P).

  • The Electric Parking Brake (EPB) is applied.

  • The vehicle's brakes are firmly applied during operation of the ASPC system.

  • The vehicle is brought to a standstill via light and gentle application of the brake pedal.

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

If an ASPC system fault is detected, the instrument panel displays a message indicating that ASPC is not available.

Some detected faults may allow the ASPC system to operate in descent control mode only. In this event, the instrument panel displays a message indicating that ASPC can only operate in descent control mode. Using the SET+ button adjusts the set speed for descent control mode. Switching the ignition off and on again may reset the ASPC system.

If a detected fault persists, consult a retailer/authorized repairer.
