Comfort pressure speed warning
If the maximum speed of the preset comfort pressure is exceeded and the tire pressure is below a defined limit, a warning message appears on the multi-function display.

Excessive Speeds for Comfort Setting

Driving at excessive speeds when the comfort pressure is active will eventually destroy the tires and that can lead to a loss of control of the vehicle, especially at high speeds.

  • Never exceed the speed specified on the warning message.
  • Always set the standard tire pressure when driving at higher speeds.
