Pulling off
›
Hook the clamp found in the vehicle tool kit into the reinforced edge of the
wheel trim.
› Push the wheel wrench through the clamp, support on the tyre and pull off the
wheel trim.
Install
› First press the full wheel trim onto the wheel rim at the valve opening provided.
Then press the full wheel trim into the wheel rim until its entire circumference
locks correctly in place. CAUTION
■ Use the pressure of your hand, do not knock the full wheel trim! Heavy knocks
mainly on the points where the full wheel trim has not been inserted into the
wheel, can result in damage to the guide and centring elements of the full wheel
trim.
■ First of all check that the theft-deterrent wheel bolt is located in the hole near
the valve before fitting the full wheel trim onto a steel wheel which is attached
with a theft-deterrent wheel bolt » page 149, Securing wheels against theft .
■ If wheel trims are retrofitted it must be ensured that an adequate flow of air is
assured to cool the brake system. ÐWheel bolts

Button for setting the tyre infla-
tion pressure control value
First read and observe the introductory information and safety warn-
ings on page 137.
The tyre control display compares the speed and thus the rolling circumference of
the individual wheels with the help of the ABS sensors. If the rolling circumfer-
ence of a wheel is changed, the warning light
in the instrument clus-
ter » page 22, Tyre control display and an audible signal sounds.
The rolling circumference of the tyre can change if: › the tyre inflation pressure is too low;
› the structure of the tyre is damaged;
› the vehicle is loaded on one side;
› the wheels of an axle are loaded heavily (e.g. when towing a trailer or when
driving uphill or downhill);
› snow chains are mounted;
› the temporary spare wheel is mounted;
› one wheel per axle was changed.

» Fig. 114 –
below the
embossing in the side surface of the lower sill.
› Ensure that the entire surface of the lifting jack base plate rests on level
ground and is located in a vertical position to the area » Fig. 114 where the claw
grasps the web. £
