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 lead to an accident, resulting in vehicle damage or personal injury.

WARNING

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

NOTES

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

NOTES

The vehicle's cruise control and speed limiter systems are disabled during operation of the ASPC system.

The ASPC button is located on the centre 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).

NOTES

The driver can override ASPC operation, at any time, using 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 six hours after the vehicle's electrical system is switched off. After this time, it has to be reselected, if ASPC is still required when the vehicle's electrical system 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 deselection. The instrument panel also displays an ASPC off confirmation message.

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 normal 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 travelling 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 descent control mode’s default speed. The currently selected driving mode determines the descent control mode’s default speed. The default speed varies from a minimum of 3.5 km/h (2.2 mph) and up to a maximum of 12 km/h (7.5 mph).

  4. The ASPC system maintains the descent control mode's default speed. ASPC exits descent control mode if it detects the use of the accelerator pedal, or the set speed is increased via the speed control switch. See ALL SURFACE PROGRESS CONTROL (ASPC) SETTINGS.

    NOTES

    Descent control mode resumes when the accelerator pedal is released and the set speed has not been increased via the speed control switch.

    NOTES

    If the set speed is increased via the speed control switch, 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 set speed.

NOTES

The driver’s seat belt must be buckled and all 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 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 the braking system and torque from the electric motors.

Full function mode should be used for all other manoeuvres 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.

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

  • Neutral (N) or Park (P) is selected.

  • 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 the ASPC 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 ASPC system faults may allow the 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. In this event, the set speed is adjusted via the speed control switch. Switching the vehicle's electrical system off and on again may reset the ASPC system.

If a detected ASPC system fault persists, consult a retailer/authorised repairer.
