Wheels and tyres
Removing
– Insert the plastic clip into the cap until the inner retaining
notches on the clips touch the collar of the cap and then re-
move ⇒ Fig. 134.
Fitting
– Insert the caps as far as they will go over the wheel bolts.
The wheel bolt caps are stored in a box on the spare wheel or in the spare
wheel well.

The tyre pressure monitoring system uses ABS sensors to compare the revo-
lutions and the circumference of each wheel. Should the circumference of
any wheel change, the warning lamp in the general instrument panel
⇒ page 76 will light up and an audible warning will be heard.
Tyre circumference may change if:
● Tyre pressure is too low
● Tyre structure is damaged ●
Vehicle load not evenly distributed
● Wheels on one axle are subjected to greater load, (e.g. driving with trail-
er, uphill, downhill)
● Snow chains are fitted
● The temporary spare wheel is fitted
● One wheel on the axle has been changed
Basic system settings
Should the tyre pressure change or if one or more wheels are changed or
the position of the wheel on the vehicle is changed, e.g. changing round the
front and rear wheels, or where a warning lamp lights up when driving, the
system must be adjusted as follows:
● Inflate all tyres to the prescribed pressures ⇒ page 197.
● Switch the ignition on.
● Hold the
⇒ Fig. 135 button down for at least 2 seconds. The warn-
ing lamp will light up when the button is pressed. The system memory is
also deleted and a new calibration system will begin, which is indicated by
an audible warning before the warning lamp switches off .
● If the warning lamp remains lit and does not switch off, not even once
the basic setting process is complete, this indicates a fault in the system.
Contact an Official Service.
The warning lamp lights up
If the pressure on at least one tyre is significantly lower than the pressure
set by the driver, the warning lamp ⇒
will light up.
The warning lamp flashes
If the warning lamp flashes, there is a fault in the system. Contact a special-
ised service to have it fixed.
