– Grip the box spanner as close to the end as possible and
turn the wheel bolts about one turn anti-clockwise
⇒page 251, fig. 230 -arrow-.
Tightening
– Fit the box spanner as far as it will go over the wheel
bolt7).
– Grip the box spanner as close to the end as possible and
tighten the bolt firmly by turning clockwise.
WARNING
To avoid accidents, the wheel bolts should only be loosened
slightly (about one turn) before raising the vehicle with the jack*.
Note
•
Do not use the hexagonal socket in the screwdriver handle to
loosen or tighten the wheel bolts.
•
If the wheel bolt is very tight, it may be possible 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.
Raising the vehicle
The vehicle must be raised with the jack* to remove the
wheel.Each jacking point is marked by a recess underneath the
vehicle ⇒fig. 231.
– Place the jack underneath the jacking point closest to
the wheel being changed. Make sure the base plate is
flat on the ground.
– Wind up the jack by the knob until the claw of the jack
completely surrounds the seam on your vehicle
⇒fig. 232.

– Now fit the crank handle onto the jack by inserting it
in the opening on the knob ⇒page 252, fig. 232. Turn the
crank handle clockwise or anti-clockwise to secure it in
place.
– Raise the vehicle by winding the crank handle until the
defective wheel is clear of the ground.Recesses at the front and rear of the door sills mark the jacking
points ⇒page 252, fig. 231. There is one jacking point for each
wheel. The distance from the jacking points to the wheel arches is
approximately 20 cm at the front and 40 cm at the rear. The jack may
only be applied at the seam of the jacking points shown.
An unstable surface under the jack may cause the vehicle to slip off
the jack. Always provide a firm base for the jack on the ground. If
necessary use a large, strong board or similar support. On a hard,
slippery surface (such as tiles) use a rubber mat or similar to prevent
the jack from slipping.
WARNING
•
Prevent the base of the jack from slipping – risk of injury.
•
The car can be damaged if the jack is not applied at the correct
jacking points. There is also a risk of injury since the jack can slip
off suddenly if it is not properly engaged.
Taking off the wheel and putting on the spare wheel
Step-by-step instructions for taking off the wheel and
putting on the spare wheel.Change the wheel as described below after loosening the
wheel bolts and raising the vehicle with the jack*.
Taking off the wheel
–Using the hexagonal opening in the screwdriver handle
(provided in the vehicle's tool kit), unscrew the wheel bolt
nearest to the top and place the bolt on a clean surface
⇒fig. 233.

Technical data terminal must not touch metal parts of the vehicle: this can cause
short circuiting.
•
Do not bend over the batteries – risk of acid burns.
•
The screw plugs on the battery cells must be screwed in firmly.
•
Keep sparks, flame and lighted cigarettes away from batteries:
the gases given off can cause an explosion.
•
If jump-starting another vehicle, position the jump leads in
such a way that they cannot come into contact with any moving
parts in the engine compartment of the other vehicle.Caution
Please note that the above method of connecting the leads is meant
for jump-starting your vehicle. If jump-starting another vehicle, you
should not connect the negative lead (–) to the negative terminal of
the discharged battery, but directly to the engine block or a solid
metal part bolted to the engine block. If the battery of the other
vehicle does not have a gas vent, there is a risk that a mixture of
oxygen and hydrogen gas can accumulate and cause an
explosion.Tow-starting and towing awayGeneral notes
Points to observe when tow-starting or towing awayIf you use a towrope:
Notes for the driver of the towing vehicle
– The towrope must be taut before driving off.– Engage the clutch very gently when starting to move; on
vehicles with automatic gearbox press the accelerator
slowly.
Notes for the driver of the towed vehicle
– The ignition should be switched on so that the turn
signals, horn, windscreen wipers and washers can be
used. Please ensure that the steering wheel is unlocked
when you switch on the ignition, and that it moves freely.
–Put gear lever in neutral (manual gearbox) or move
selector lever to position N (automatic gearbox).
– The brake servo and power steering only work when the
engine is running. Considerably more effort is required
on the brake pedal and steering wheel when the engine
is switched off.
– Ensure that the towrope remains taut at all times when
towing.
Towrope or towbar
It is easier and safer to tow a vehicle with a towbar. You should only
use a towrope if you do not have a towbar.
A towrope should be slightly elastic to reduce the loading on both
vehicles. It is advisable to use a towrope made of synthetic fibre or
similar material.
Attach the tow-rope or tow-bar only to the towing anchorages
intended for this purpose ⇒page 258 or ⇒page 259.
Driving technique
Towing requires some experience – especially when using a
towrope. Both drivers should be familiar with the technique required
for towing. Inexperienced drivers should not attempt to tow-start or
tow away another vehicle.

Incorrect handling of the high-voltage element of xenon gas-
discharge bulbs* can have potentially fatal consequences.
•
When changing bulbs, please take care not to injure yourself on
sharp edges, in particular on the headlight housing.Caution
•
Always remove the ignition key before carrying out any work on
the electrical system - danger of short circuiting!
•
Switch off the lights or parking lights before you change a bulb.
•
Take good care to avoid damaging any components.
•
Removing the lights in particular can lead to the paintwork
becoming damaged. This is another reason why we recommend
having the bulbs changed by a qualified workshop.For the sake of the environment
Please ask your specialist retailer how to dispose of used bulbs in
the proper manner.
Note
Place the parts you have removed on a soft cloth so that they do not
become scratched.•
Please check at regular intervals that all lighting (especially the
exterior lighting) on your vehicle is functioning properly. This is not
only in the interest of your own safety, but also in that of all other
road users.
•
Before changing a bulb, make sure you have the correct new
bulb.
•
Do not touch the glass part of the bulb with your bare hands, use
a cloth or paper towel instead. Otherwise, the fingerprints left on
the glass will vaporise as a result of the heat generated by the bulb,
be deposited on the reflector and impair its surface.
Bulbs with a bayonet fastenerBulbs with a bayonet fastener must be changed as follows:
Removing the bulb
– Lightly press the defective bulb into the bulb holder, then
turn it anti-clockwise and remove it.
– Do not touch the glass part of the new bulb with your
bare hands, use a cloth or paper towel instead.
Fitting the bulb
– Fit the new bulb, pressing it into the bulb holder, and turn
it clockwise as far as it will go.
– If necessary, use a cloth to remove any fingerprints from
the glass part of the bulb.Bulb holders with a bayonet fastener
