Towing and tow-starting
Points to remember
G
Risk of accident and injury
Vehicles with BlueHYBRID*: make sure that
you read the "BlueHYBRID" supplement. You
may otherwise fail to detect dangers.
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.
G
Risk of accident
The vehicle is braked when Hold or Distronic
Plus* is activated. Therefore, deactivate
HOLD and Distronic Plus if the vehicle is to be
towed.
It is better to have the vehicle transported
than to have it towed.
When towing, observe the legal requirements
in all countries concerned.
