You will place great stresses on the power steering system if the steering is turned to
full lock when the vehicle is stationary. Turn ing the steering to full lock in such a situa-
tion 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 ba ttery is charged to a specific range when
engine is running. It also op erates 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 25.
Caution
Do not leave the steering at full lock fo r 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 pressure monitoring system*The tyre pressure monitoring 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 30. The tyre pressure moni-
toring system functions 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,
the wheels of an axle are loaded heavily (e.g. when towing a trailer or when driving
uphill or downhill),
the vehicle is operated in unfavourable wi nter conditions or on an unfirm ground,
snow chains or emergency wheel are mounted,
the driver has a sporty style of driving (with sharp acceleration and high speed
when cornering).
Basic setting of the system
After changing the tyre inflation pressures or after changing one or several wheels, a
basic setting of the system mu st be carried out as follows.
Inflate all tyres to the specified inflation pressure page 173.
Switch on the ignition.
Press button
fig. 127 for more than 2 seconds. While pressing the button,
the warning light
lights up. At the same time the basic values are stored, which is
confirmed with an acoustic sound and then the warning light
goes out.
