FULL FUNCTION MODE

WARNING

Make sure the relevant safety warnings have been read and understood before using All Terrain Progress Control (ATPC). See ALL TERRAIN PROGRESS CONTROL (ATPC) SAFETY.

Full function mode builds on the features available in descent control mode, to further enhance the vehicle's ability to gain traction in challenging conditions. The benefits of full function mode include:

  • Making a controlled ascent.

  • Pulling away from a standstill.

  • Driving on unstable and slippery surfaces.

NOTES

Full function mode is only available if the driver’s seat belt is buckled and all doors are closed. The instrument panel displays a warning message if these conditions are not met.

To enter full function mode, first enable ATPC. See ENABLING ALL TERRAIN PROGRESS CONTROL (ATPC).

The vehicle is now in descent control mode.

With the vehicle stationary, move the rocker switch (4) up to the SET+ position (1) with the brake pedal firmly pressed to enter full function mode.

With the vehicle moving, move the rocker switch (4) up to the SET+ position (1) to enter full function mode

To adjust the vehicle’s speed while full function mode is active:

  • Move the switch (4) up to the SET+ position (1) to raise the vehicle’s set speed, or:

  • Move the switch (4) down to the SET– position (2) to lower the vehicle’s set speed.

  • Press the CAN button (3) to cancel the speed adjustment, and revert back to descent control mode.

  • Press the RES switch (4) to resume the set speed, if the vehicle’s speed has been lowered through gentle application of the brake pedal.

WARNING

The RES switch should only be used if the driver is aware of the set speed and intends to return to it. Pressing the RES switch when not aware of the set speed may lead to a loss of control of the vehicle. Loss of vehicle control could potentially lead to serious injury or death.

Incremental increases or decreases in the set speed vary depending on the vehicle’s current set speed, as follows:

  • 0.5 km/h (0.3 mph) increments if the vehicle’s set speed is between 0 and 5 km/h (0 and 3 mph).

  • 1 km/h (0.6 mph) increments if the vehicle’s set speed is between 5 and 10 km/h (3 and 6 mph).

  • 2 km/h (1 mph) increments if the vehicle’s set speed is between 10 and 30 km/h (6 and 19 mph).

The minimum set speed is 3 km/h (2 mph) when the vehicle is in high range. The minimum set speed is 1.8 km/h (1 mph) when the vehicle is in low range. See SELECTING HIGH AND LOW RANGE.

ATPC reverts back to descent mode if:

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

  • The Electric Parking Brake (EPB) is applied.

  • The brake pedal is firmly pressed.

  • The vehicle is brought to a standstill through light application of the brake pedal.

Light, gentle use of the brake pedal lowers the full function mode set speed. ATPC maintains the speed at which the vehicle is travelling if the brake pedal is released.

A slight pulsation may be felt through the brake pedal when ATPC is actively braking.
