Depending on driving speed and engine speed, you can shift up or down at any time.

Gear changes which would exceed the upper or lower engine speed limit are not executed by the controller.

There is no automatic upshift at the upper engine speed limit in selector lever position M. Upshift suppression can be cancelled by kickdown operation. If, for example, the engine speed limit is reached during overtaking and the automatic upshift does not occur, the transmission in this case shifts up as a result of kickdown operation.

  • Select an appropriately low gear on upward and downward slopes.
    This will ensure optimum use of engine power and engine braking.

In order to shift up automatically at the upper engine speed limit:

  • Depress the accelerator pedal beyond the fullthrottle point (kickdown).


  • For a brief stop (e.g. at a traffic light), leave the selector lever in drive position and hold the vehicle with the brake pedal.
  • Do not hold the car on a slope using the accelerator. Use the brake pedal or the handbrake instead.
  • Before leaving the vehicle, always apply the handbrake and move the selector lever to position P.


  • Go easy on the accelerator!
  • When parking or manoeuvring in a small space, control the speed by careful use of the footbrake.

Driving in winter
In wintry road conditions it is advisable to take steep inclines in manual mode. This prevents gear changes occurring that could cause wheelspin.

Tow-starting, towing

  • Please see the chapter "TOWING" on page 234.
