Changing a wheelPreliminary workThe following steps should be carried ou
t before actually changing the wheel.
– If it is necessary to change a wheel, park
the vehicle as far aw
ay as possible from
the traffic flow. The place you choose should be
level
.
– Have all the occupants
get out
. While changing a wheel, the occupants of the
vehicle should not stand on the ro
ad (e.g. 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 185 out of the luggage
compartment.
WARNING
If you find yourself in flowing traffic switch 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 si
tting on the raised
jack - danger of
suffering injury.
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 unexpectedly rolling away.
Note
Comply with the national legal regulations.
Changing a wheelAlways change a wheel on a level surface as far as possible. – Take off the full wheel trim*
page 188 or the caps
page 188.
– Slacken the wheel bolts
page 189.
– Jack up the vehicle until the wheel to
be changed is clear of the ground
page 189.
– 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, alternatel
y and diagonally using the wrench (cross-
wise)
page 189.
– 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!
When fitting on unidirectiona
l tyres, ensure that the tyres rotate in the correct
direction
page 178.
Subsequent stepsAfter changing the wheel, you mu
st perform the following steps.
– Stow the vehicle tool kit in the space provided.– Stow the replaced wheel in the luggage compartment.–
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. Steel and light alloy wheels must be tightened to a tightening torque of
120 Nm
.

WARNING
The non-insulated parts of the terminal clamps must never make contact
with each other. Furthermore, the cable connected to the positive terminal of the battery must not come into contact with electrically conducting parts of the vehicle - risk of a short circuit!
Do not affix the jump starting cables to the negative terminal of the
discharged battery. There is
the risk of detonating gas seeping out the battery
being ignited by the strong spark which
results from the engine being started.
Do not affix the cable end to parts of the fuel and brake system.
Run the jump-start cables so that they cannot be caught by any rotating
parts in the engine compartment.
Do not bend over the batteries - risk of caustic burns!
The vent screws of the battery
cells must be tightened firmly.
Keep any sources of ignition (naked
flame, smouldering
cigarettes etc.)
away from the battery - risk of an explosion!
Never jump-start the batteries which have a too low electrolyte level - risk
of explosion and caustic burns!Jump-starting on vehicles with the “START-STOP” systemOn vehicles with the “START-STOP” syst
em, the jump-starting cable must not be
connected directly to the negative terminal
of the vehicle battery, but only to the
engine earth

Tow-starting and towing vehicleGeneralPlease pay attention to the following instru
ctions if you are going to use a tow rope:
Driver of the towing vehicle– Do not drive off until the tow rope is taught. – Release the clutch particularly gently when starting off.Driver of the towed vehicle– Switch the ignition on so that the steeri
ng wheel is not blocked and you can also
operate the turn signal lights, the headlight flasher, the windscreen wipers and windscreen washer system.
– Take the vehicle out of gear or move the selector lever into position
N if your
vehicle is fitted with an automatic gearbox.
– Note that the brake servo unit and power steering only operate if the engine is
running. You will require significantly greater physical force to depress the brake pedal and to steer the vehicle
if the engine is not running.
– Ensure that the tow rope is always kept taught. Tow rope or tow bar A tow
bar
is safest way of towing a vehicle and also minimizes any shocks. You can use
a tow
rope
only if a suitable tow bar is not available.
The tow rope must be elastic to protect the
vehicle. Thus one shou
ld only use plastic
fibre rope or a rope made out
of a similarly elastic material.
Attach the tow rope or the tow bar only to the
towing eyes
provided for this purpose
page 193, “Front towing eye” and
page 193, “Rear towing eye”.
Driving style Towing another vehicle requires a certain am
ount of practice. Both drivers should be
familiar with the particular points about to
wing a vehicle. Unskilled drivers should not
attempt to tow in another vehicle or to be towed in.

– Switch on the ignition. – Wait until both vehicles are moving
then release the clutch pedal slowly.
– Depress the clutch pedal fully when the engine fires and take the vehicle out of
gear.
WARNING
There is high risk of having an accident when tow-starting a vehicle, when for example the towed vehicle ru
ns into the towing vehicle.
Caution
Vehicles which are fitted with a catalytic
converter should not be tow-started over a
distance of more than 50 metres. Unburnt fu
el may get into the catalytic converter and
damage it.Towing in a vehicle fitted with a manual gearboxPlease refer to the additional instructions
page 192.
The vehicle can be towed in with a tow bar
or a tow rope or with the front or rear
wheels raised. The maximum towing speed is
50 km/h
.
Towing of a vehicle with an automatic gearboxPlease refer to the additional instructions
page 192.
The car can be towed in with a tow bar or
a tow rope. Refer at the same time to the
following guidelines:
Move
selector lever into N
.
The maximum towing speed is
50 km/h
.
The maximum permissible
towing distance is
50 km
. The gear oil pump does not
operate when the engine is not running; th
e gearbox would not be
adequately lubri-
cated at higher speeds and ov
er longer towing distance.
Caution
If the vehicle is towed in by a recovery vehicle,
it should only be towed in with the front
wheels raised. If the vehicle is raised
at rear, the automatic gearbox is damaged!
Note
The vehicle must be transported on a special vehicle or trailer if it is not possible to tow in the vehicle in the way described or if th
e towing distance is greater than 50 km.
