– Have all the occupants get out. While changing a wheel, the
occupants of the vehicle should not stand on the road (it is
better behind a crash barrier).
– Apply the handbrake firmly.
– Engage 1st gear or if your vehicle is fitted with an automatic
gearbox, position the selector lever into position P .
– If a trailer is coupled, uncouple it.
– Take the vehicle tool kit and the spare wheel ⇒ page 229
out of the luggage compartment.
Caution
If you have to change a wheel on a slope first block the opposite wheel
with a stone or similar object in order to secure the vehicle from unexpect-
edly rolling away.
Note
Comply with the national legal regulations.
Changing a wheel
Always change a wheel on a level surface as far as possible.
– Take off the full wheel trim/wheel trim cap ⇒page 232,
“Wheel trim caps*” or the caps ⇒page 232, “Wheel bolts with
caps*”.
– Slacken the wheel bolts ⇒ page 233.
– Jack up the vehicle until the wheel is clear of the ground ⇒page 233.
– Unscrew the wheel bolts and place them on a clean surface (cloth, paper etc.).
– Take off the wheel.
– Fit on the spare wheel and tighten the wheel bolts slightly.
– Lower the car.
– Tighten the wheel bolts firmly, alternately and diagonally using the wheel wrench ⇒page 233.
– Mount the full wheel trim/wheel trim cap or the caps.
Note
•All bolts must be clean and must turn easily.
•You must never grease or oil the wheel bolts!
WARNING
•If you find yourself in flowing traffic put on the hazard warning
lights system and place the warning triangle on the side of the road
at the prescribed distance from your vehicle while observing all
national legal provisions. In this way you are protecting not only
yourself but also other road users.
•Never start the engine with the vehicle sitting on the raised jack
- danger of suffering injury!

Subsequent steps
After changing the wheel, you must perform the following steps.
– Stow and attach the replaced wheel in the spare wheel well.
– Stow the vehicle tool kit in the space provided.
–Check the tyre pressure on the spare wheel just mounted as
soon as possible.
– Have the tightening torque of the wheel bolts checked with
a torque wrench as soon as possible. The tightening torque
must be 120 Nm.
– Have the defective tyre repaired as soon as possible.
Note
•If you find, when changing the wheel, that the wheel bolts are corroded
and difficult to turn, the bolts must be replaced before checking the tight-
ening torque.
•Drive cautiously and only at a moderate speed to a workshop where
the tightening torque can be checked.
Full wheel trim*
Removing
– Hook the clamp (found in the vehicle toolkit) into the reinforced edge of the full wheel trim.
– Push the wheel key through the clamp, support the wheel key at the tyre and pull off the wheel trim.
Installing
– First press the full wheel trim onto the wheel at the valve opening provided. Then press the full wheel trim into the
wheel in such a way that its entire circumference locks
correctly in place.
Caution
Use the pressure of your hand, do not knock on 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 centering
elements of the full wheel trim.WARNING
It is necessary to observe the guidelines given on ⇒page 222,
“New tyres and wheels” if the vehicle is subsequently fitted with
tyres which are different to those it was fitted with at the works.

Changing a wheel
– Turn the wheel bolt which is farthest to the top fully out with
the hexagon socket in the screwdriver handle (car tool kit)
and place the bolt down on a clean surface ⇒page 234,
fig. 177 .
– Screw the assembly pin (car tool kit) into the vacant hole ⇒page 234, fig. 178.
– Unscrew the remaining wheel bolts as described above.
– Take off the wheel.
Fitting on wheel
– Push the spare wheel over the assembly pin.
– Screw in the wheel bolts and tighten them slightly with the aid
of the hexagon socket.
– Unscrew the assembly pin and screw in the remaining wheel bolt also slightly.
The wheel bolts must be clean and must turn easily.
The hexagon socket in the handle of the screwdriver makes it simpler to
fit on the wheel bolts. The reversible blade should be pulled out for this
step.
When fitting on unidirectional tyres, ensure that the tyres rotate in the
correct direction ⇒page 225.
Note
Do not use the hexagon socket in the handle of the screwdriver for slack-
ening or tightening the wheel bolts.
Securing wheels against being stolen
You need a special adapter for slackening the safety
wheel bolts.
– Pull off the full wheel trim/cap from the wheel hub or cap from
the safety wheel bolt.
– Push the adapter with its toothed side into the inner toothing of the safety wheel bolt right down in such a way
that only the outer hexagon is jutting out ⇒fig. 179.
– Push the wheel wrench fully onto the adapter .
– Slacken the wheel bolt, or tighten it firmly ⇒page 223.
– Reinstall the full wheel trim/wheel cap after removing the adapter or place the cap onto the safety wheel bolt.
