Wheel bolts
Fig. 152 Changing a wheel: loosening the wheel bolts
Fig. 153 Changing wheel: tyre valve ① and location of the anti-theft wheel bolt ②
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Only the spanner delivered with the vehicle should be used to loosen the wheel bolts.
Only loosen the wheel bolts by approximately one turn before raising the vehicle with the vehicle
jack.
If the wheel bolt is very tight, you may be able to loosen it by pushing down the end of the spanner
carefully with your foot. Hold on to the car for support and take care not to slip.
Loosening the wheel bolts
•Fit the box spanner over the wheel bolt as far as it will go ⇒ Fig. 152.
•Hold the end of the box spanner and turn the wheel bolt one turn anticlockwise ⇒.
Loosening the anti-theft wheel bolt
The anti-theft wheel bolt must be bolted into position ⇒ Fig. 153② on wheels with a wheel cover.
Otherwise, it will not be possible to fit the wheel cover.
•Take the adapter for anti-theft wheel bolts out of the vehicle toolkit.
•Insert the adapter into the anti-theft wheel bolt ⇒ Fig. 153. Push it in as far as it will go.
•Insert the box spanner into the adapter as far as it will go.
•Hold the end of the box spanner and turn the wheel bolt one turn anticlockwise ⇒.
Important information about the wheel bolts
The design of the wheel rims and wheel bolts is matched to the factory-fitted wheels. If different
rims are fitted, the correct wheel bolts with the right length and correctly shaped bolt heads must be
used. This ensures that wheels are fitted securely and that the brake system works properly.
In certain circumstances, wheel bolts from a vehicle of the same model series may not be used.
Tightening torque for the wheel bolts
The tightening torque for wheel bolts for steel and alloy wheels is 110 Nm. The tightening torque
should be checked with a torque wrench immediately after changing a wheel.
If the wheel bolts are corroded and difficult to turn, they must be replaced and the wheel hub
threads cleaned before the tightening torque is checked.
Never grease or lubricate the wheel bolts or the threads of the wheel hub. This could cause them to
loosen while the vehicle is in motion, even if the required torque setting is used.
Ignoring any of the items on this important safety checklist can lead to accidents and severe
injuries.
•Always follow the instructions in the checklist and observe the general safety procedures.
WARNING

Find a firm and level surface suitable for lifting the vehicle.
Stop the engine, select a gear on a manual gearbox or with an automated manual
gearbox, move the selector lever to D or R with the ignition switched onChanging gear
then apply the handbrake firmly Braking, stopping and parking.
Chock the wheel diagonally opposite using the collapsible chocks or other suitable objects.
Loosen the wheel bolts on the wheel that is being changed Wheel bolts.
Find the jacking point under the vehicle which is closest to the wheel that is being
changed.
Raise the vehicle jack until it just fits under the jacking point of the vehicle.
Ensure that the foot of the jack is resting securely on the ground with its whole surface and
that the foot of the jack is positioned precisely, i.e. vertically beneath the point of
application .
Position the vehicle jack. At the same time, continue to crank the claw up until it is in
position around the vertical rib underneath the vehicle .

Checklist
To ensure your own safety and that of your passengers, observe the following actions in the
specified order ⇒:
Incorrectly tightened wheel bolts can loosen while the vehicle is in motion and cause
accidents, serious injury, and loss of control of the vehicle.
•Only use wheel bolts that belong to the wheel.
•Never use different wheel bolts.
•The wheel bolts and threads of the wheel hubs must be clean, free from oil and grease,
and turn easily.
•Always use the box spanner placed in the vehicle at the factory to loosen and tighten the
wheel bolts.
•Only loosen the wheel bolts by approximately one turn before raising the vehicle with the
vehicle jack.
•Never grease or lubricate the wheel bolts or the threads of the wheel hub. This could
cause them to loosen while the vehicle is in motion, even if the required torque setting is
used.
•Never remove the bolts on rims with bolted-on rings.
•If the tightening torque of the wheel bolts is too low, the wheel bolts and rims can loosen
while the vehicle is in motion. The wheel bolts and threads can be damaged if the
tightening torque is too high.
WARNING

Crank the vehicle jack further until the wheel is just clear of the ground.

Driving tips when towing
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Towing requires some experience, especially when using a tow rope. Both drivers should be
familiar with the technique required for towing. Inexperienced drivers should not attempt to tow.
When driving, ensure that you do not pull too hard on the towing vehicle and take care to avoid
jerking movements. When towing on an unpaved road, there is always a risk of overloading and
damaging the anchorage points.
You can still use the turn signals if your vehicle is towed with the hazard warning lights and ignition
switched on. Move the turn signal lever to signal the required direction. The hazard warning lights
will not flash while the turn signal is being used. The hazard warning lights will start flashing
automatically as soon as the turn signal lever is moved back to the neutral position.
Notes for the driver of the towed vehicle:
•Leave the ignition switched on to prevent the steering wheel from locking, and so that the turn
signals, horn, windscreen wipers and washers can be used.
•As the power assisted steering does not work if the engine is not running, you will need more
strength to steer than you normally would.
The towing eye must always be screwed firmly into the mounting. Otherwise, the towing eye
can be ripped out of the mounting when the vehicle is being tow-started or towed.
