Intelligent Technology 160brake pedal firmly and hold it in this position in order to achieve the shortest
possible braking distance.
The Brake Assist is able to help you achieve a shorter braking distance in emergency
situations by rapidly producing the pressure required in the brake system. It fully
exploits the attributes of the ABS. After you release the brake pedal, the function of
the Brake Assist is automatically switched off and the brakes operate in the normal
way.
The Brake Assist is part of the ESP system. If a fault occurs in the ESP, the Brake Assist
function is also not available. Further information on the ESP ⇒page 155.
WARNING
•
The Brake Assist is also not able to overcome the physical limits of your
vehicle in terms of the braking distance required.
•
Adapt your speed to the conditions of the road surface and to the traffic
situation.
•
The increased safety offered by the Brake Assist must not tempt you to
take a greater safety risk than otherwise.
Electrohydraulic power steeringThe 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.
If there is a fault in the power steering, the warning light lights up in the instrument
cluster
⇒page 29.
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 rolling circumference of the individual wheels. If the tyre
inflation pressure is significantly changed and thus the rolling circumference of a
wheel, the warning light
lights up in the instrument cluster ⇒page 35. The tyre
inflation pressure-control system functions late or too sensitively if:
