Full Function Mode

Full function mode is selected manually by pressing the speed control SET+ switch when descent control mode is active.

Full function mode is used when speed control is required. For example, while making an ascent, pulling away on level ground, or when driving on difficult terrains. Full function mode can be used in Drive (D), Sport (S) - either in automatic and manual gear selection modes - and Reverse (R). If full function mode is selected when the vehicle is in either Park (P) or Neutral (N), the function is inhibited, and displays the following message in the IC message center: - 'ATPC on, descent only, select gear'.

Full function mode can be selected while the park brake is applied, but the vehicle will not pull away automatically until the park brake is manually released by the driver.

NOTE: The park brake may be released automatically when the driver selects Drive (D) Sport (S) or Reverse (R) and presses the accelerator pedal. But since ATPC operation is meant to promote a 'pedals off' operation, preventing loss of traction when driving the vehicle in adverse conditions (ice, snow). This action would override the system and might affect the launch composure or induce a wheel slip event.

Full function mode operating criteria and entry set speed is identical to descent control mode.

System feedback, provided by the IC and ATPC switch indicator lamp, informs the driver of the ATPC system status.

Full function mode set speed is modified by the driver as follows:

Increase the set speed by pressing the cruise control SET+ switch.
Decrease the set speed by pressing the speed control SET- switch or by gently applying the brake pedal.

NOTE: For safety reasons if the driver applies a brake pressure above 40 bar (580 lbf/in² ), the system overrides the full function mode.

Full function can be cancelled by pressing the ATPC switch in full function mode. It turns the whole feature off and ATPC becomes OFF. If the speed control cancel switch is pressed from full function mode, full function mode gets cancelled to descent control mode.
