•The increased safety offered by the Brake Assist must not tempt
you to take a greater safety risk than otherwise.
Power steering*
The power steering enables you to steer the vehicle with less physical
force.
The steering characteristics can be changed by a specialist garage.
You will place great stresses on the power steering system if the steering
is turned to full lock when the vehicle is stationary. Turning the steering to
full lock in such a situation will be accompanied by noises.
It is still possible to fully steer the vehicle if the power steering fails or if the
engine is not running (vehicle being towed in). The only difference is that
greater physical effort is required.
It is possible that the hydraulic pump of the power steering will not run due
to the low vehicle network voltage if the battery has gone flat and the
engine must started with the help off jump leads. This condition will be
indicated by lighting up of the warning light.
The power steering operates again if the battery is charged to a specific
range when engine is running. It also operates again, if the engine can be
started with its own battery.
Caution
Do not leave the steering at full lock for more than 15 seconds when the
engine is running - risk of damaging the power steering!
Note
Have the steering inspected as soon as possible by a specialist garage if
there is a leak or fault in the system.
Tyre inflation pressure-control system*
The tyre inflation pressure-control system compares with the aid of the
ABS sensors the speed and also the roll ing circumference of the individual
wheels. If the inflation pressure and therefore the rolling circumference of
a wheel has changed significantly, the warning light
lights up in the
dash panel ⇒page 34. The tyre inflation pressure-control system func-
tions late or too sensitively if:
•the structure of the tyre is damaged,
•the vehicle is loaded to one side or with a load on the roof,
