Safety-relevant functions are restricted or not
available if:
R
the engine is not running.
R
the brake system or the power steering is
malfunctioning
R
the voltage supply or the vehicle's electrical
system is malfunctioning.

force may be required to steer the vehicle or
to brake. There is a risk of an accident.
In such circumstances, use a towing bar.
Make sure that the steering is moving freely
before towing.

WARNING
If the weight of the vehicle to be towed or tow-
started is greater than the permissible gross
weight of your vehicle:
R the towing eye could detach itself
R
the vehicle/trailer combination could over-
turn.
There is a risk of an accident.
When towing or tow-starting another vehicle,
its weight should not be greater than the per-
missible gross weight of your vehicle.
Information on your vehicle's gross vehicle
weight rating can be found on the vehicle
identification plate (

with a tow rope:

both vehicles.

towed.

eye.
