Towing the vehicle
i For information on towing and
transporting the vehicle refer to the
Operator’s Manual.
GWarning!
When you depress the brake pedal for the first
time when towing, less brake pedal pressure
is required and the brake pedal travel is longer
than usual. The same applies if a malfunction
occurs, for example when the vehicle system
voltage is too low. If required, you have to
depress the brake pedal further. Adapt your
speed and driving accordingly.
Depress the brake pedal fully and release it
again before towing. When all necessary
systems are operational again, the required
brake pedal pressure and the brake pedal
travel are back to normal.
