Wheel changing Make the following preparations and
observe the following information:
● Park the vehicle on a level, firm and non-skid surface. The front
wheels must be in the straight- ahead position.
● If necessary, place a chock under
the wheel diagonally opposite the wheel to be changed.
● Apply the parking brake and engage first gear, reverse gear or
P .● If the ground on which the vehicle
is standing is soft, a solid board
(max. 1 cm thick) should be
placed under the jack.
● Take heavy objects out of the vehicle before jacking up.
● No people or animals may be in the vehicle when it is jacked-up.
● Never crawl under a jacked-up vehicle.
● Do not start the vehicle when it is
raised on the jack.
● Before screwing in the wheel bolts, clean them.9Warning
Do not grease wheel bolts.
Tightening torques
Caution
If the vehicle is equipped with alloy
wheels, tighten the wheel bolts
manually at least for the first five
turns.
There are two different types of
wheels with two different bolts and tightening torques.
Tightening torque for alloy wheels is
100 Nm.
Tightening torque for steel wheels is
115 Nm.
9 Warning
Ensure to use always the correct
wheel bolts if changing the
wheels. When installing the spare
wheel, the bolts for alloy wheels can also be used.

3. When, after a wheel change, no wheel is placed in the spare wheelwell, fasten the wing nut and close
the floor cover.
4. After a wheel change back to a full
size wheel, place the spare wheel
outside up in the well and secure
with the wing nut.
Temporary spare wheelCaution
If driving with a temporary spare
wheel, active emergency braking
has to deactivated.
Only mount one temporary spare
wheel. The permissible maximum
speed on the label on the temporary
spare wheel is only valid for the
factory-fitted tyre size.
Do not drive faster than 50 mph. Take curves slowly. Do not use for a long
period of time.
Fitting the spare wheel
Make the preparations given for
wheel changing 3 203 and observe
the following information:
● Never change more than one wheel at once.
● Use the jack only to change wheels in case of puncture, not
for seasonal winter or summer
tyre change.
● The jack is maintenance-free.
1. Disengage wheel bolt caps with a
screwdriver and remove.
Steel wheels with cover: Pull off
the wheel cover.
Alloy wheels: Disengage wheel
bolt caps with a screwdriver and
remove. To protect the wheel,
place a soft cloth between the
screwdriver and the alloy wheel.
2. Fold out the wheel wrench and install ensuring that it locates
securely and loosen each wheel
bolt by half a turn.
The wheels might be protected by
locking wheel bolts. To loosen
these specific bolts, first attach
the adapter for the locking wheel
bolts onto the head of the bolt
before installing the wheel
wrench. The adapter is located in
the glovebox or in the load
compartment under the rear floor
cover.

Vehicle care207bolts can also be used for the steelspare wheel. In this case, the
spare wheel is secured by the
conical contact of each bolt. In this case, the washers do not come
into contact with the spare wheel.
10. Align the valve hole in the wheel cover with the tyre valve before
installing.
Install wheel nut caps.
11. Stow and secure the replaced wheel and the tools.
12. Check the tyre pressure of the installed tyre and the tightening
torque as soon as possible.
Stowing a damaged full size
wheel in the load compartment
The spare wheel well is not designed
for other tyre sizes than the temporary spare wheel. A damaged full size
wheel must be stowed in the load compartment and secured with a
strap.
Vehicle tools 3 195.To secure the wheel:
1. Position the wheel outside up close to one sidewall of the load
compartment.
2. Place the loop end of the strap through the front lashing eye on
the appropriate side.
3. Place the hook end of the strap through the loop and pull it until
the strap is fastened securely to
the lashing eye.
4. Insert the strap through the spokes of the wheel as shown in
the illustration.
5. Mount the hook to the rear lashing
eye.
6. Tighten the strap and secure it using the buckle.
If no strap is available, make sure to
store the wheel securely in the load
compartment.
