Points to remember
G
Risk of accident
If you have the vehicle towed, you must use a
rigid towing bar if:
R the engine is not running.
R there is a brake system malfunction.
R there is a malfunction in the power supply
or the vehicle's electrical system.
The power steering and the brake force boos-
ter do not work when the engine is not run-
ning. Greater braking force will then be
required and brake pedal travel will be longer.
If necessary, depress the brake pedal with full
force.
Before towing away, make sure that the steer-
ing can be moved and is not locked.
If you tow or tow-start another vehicle, its
weight must not exceed the maximum per-
missible gross vehicle weight of your vehicle. Towing and tow-starting
