2022 Land Rover Range Rover Velar All Terrain Progress Control (ATPC) Owners Manual

Do not attempt a steep descent if the ATPC system is not enabled, or if the instrument panel displays any warning messages.

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

The ATPC system cannot be enabled if the advanced tow assist, park assist, wade sensing, or parking features are currently enabled.

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

1. The driver can override the ATPC system operation, at any time, using the brake pedal or the accelerator pedal.
2. The ATPC 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.
3. The ATPC system remains enabled for 6 hours after the ignition is switched off. After this time, ATPC has to be reselected, if the system is still required when the ignition is switched on.
4. Press and release the ATPC button again to disable the system. The instrument panel extinguishes the ATPC warning lamp to confirm deselection.
5. The ATPC system operation is influenced by the current terrain response driving program selection.
6. For example, the grass gravel snow program requires gradual ATPC acceleration to help gain available wheel traction.
7. The comfort program allows increased ATPC acceleration to help improve vehicle progress. See TERRAIN RESPONSE OPERATION.

USING ALL TERRAIN PROGRESS CONTROL (ATPC)

The All Terrain Progress Control (ATPC) system has two modes of operation:

• Descent control mode: This is the default setting when the ATPC system is enabled and the vehicle is stationary. See DESCENT CONTROL MODE.The ATPC system uses the braking system to maintain an automatically set low speed, for driving down a steep descent.
• Full function mode: Is automatically entered, when the ATPC system detects the driver has requested a higher set speed, via the operation of the steering wheel’s SET + button. See FULL FUNCTION MODE.The ATPC system maintains the higher set speed by using the braking system and engine torque. The 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.

The ATPC system automatically exits full function mode and reverts back to descent control mode, 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 the operation of the ATPC system.
• The vehicle is brought to a standstill via the light and gentle application of the brake pedal.

In all of the previously listed events, the instrument panel displays a relevant information message. 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 ATPC system operation fades out and becomes temporarily inactive. When the brakes return to normal operating temperatures, the message extinguishes and the system resumes normal operation. If an ATPC system fault is detected, the instrument panel displays a message indicating that ATPC is not available. Some detected faults may allow the ATPC system to operate in descent control mode only. In this event, the instrument panel displays a message indicating that ATPC can only operate in descent control mode. Using the SET+ button increases the set speed for the descent control mode. Switching the ignition off and on again may reset the ATPC system. If a detected fault persists, consult a retailer/authorized repairer.

DESCENT CONTROL MODE

When the All Terrain Progress Control (ATPC) system enters descent control mode, the instrument panel displays a confirmation message. See ALL TERRAIN PROGRESS CONTROL (ATPC) and USING ALL TERRAIN PROGRESS CONTROL (ATPC).

Operate as follows:

1. Select the correct driving program for the current terrain. See TERRAIN RESPONSE 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 terrain response driving program determines the descent control mode’s default speed. The default speed varies from a minimum of 1.1 mph (1.8 km/h) in the low range and up to a maximum of 7.5 mph (12 km/h) in the high range. See SELECTING HIGH AND LOW RANGE.
4. The ATPC system maintains the descent control mode’s default speed. ATPC exits descent control mode if it detects the use of the accelerator pedal or the steering wheel’s SET+ button. See ALL TERRAIN PROGRESS CONTROL (ATPC) SETTINGS.
