Checking and refilling levels
Checking tyre pressure
The correct tyre pressure can be seen on the sticker on the
inside of the tank flap.
1. Read the required tyre inflation pressure from the sticker. The values refer to Summer tyres.
2. The tyre pressures should only be checked when the tyres are cold. The slightly raised pressures of warm tyres must not be re-
duced.
3. Adjust the tyre pressure to the load you are carrying.
Tyre pressure
The correct tyre pressure is especially important at high speeds. The pres-
sure should therefore be checked at least once a month and before starting
a journey.
WARNING
A tyre can easily burst if the pressure is too low, causing an accident!
● At continuously high speeds, a tyre with insufficient pressure flexes
more. In this way it becomes too hot, and this can cause tread separation
and tyre blow-out. Always observe the recommended tyre pressures.
● If the tyre pressure is too low or too high, the tyres will wear prema-
turely and the vehicle will not handle well. Risk of accident!
For the sake of the environment
Under-inflated tyres will increase fuel consumption. Tyre service life
The service life of tyres is dependent on tyre pressure, driv-
ing style and fitting.

If and when
If you have a puncture on one of the front wheels when using snow chains,
fit the compact temporary spare in place of one of the rear wheels. You can
then attach the snow chains to the wheel taken from the rear and use this
wheel to replace the punctured front wheel.
WARNING
● The tyre pressures must be checked and corrected as soon as possi-
ble.
● Do not drive faster than 80 km/h. Higher speeds can cause an acci-
dent.
● Avoid heavy acceleration, hard braking and fast cornering. Risk of ac-
cident.
● Never use two or more compact spare tyres at the same time, risk of
accident.
● No other type of tyre (normal summer or winter tyre) may be fitted on
the compact temporary spare wheel rim.
Tyre repair kit*
The tyre repair kit (for vehicles not including a spare wheel)
is stored under the floor panel in the luggage compartment. In the event of a punctured tyre, your vehicle is equipped with the Tyre Mo-
bility System.
The tyre repair kit consists of a container with sealing compound to repair
the puncture and a compressor to generate the required tyre pressure. The
kit will reliably seal punctures up to a size of about 4 mm caused by the
penetration of a foreign body into the tyre.
Note
● Seek professional assistance if the repair of a tyre puncture is not possi-
ble with the sealing compound.
Wheel change Preparation work
What you must do before changing a wheel.
– If you have a flat tyre or puncture, park the vehicle as far away
from the flow of traffic as possible. Choose a location that is as
level as possible.
– All passengers should leave the vehicle. They should wait in a
safe area (for instance behind the roadside crash barrier).
– Switch the engine off. Switch the hazard warning lights on and
place the warning triangles in position.
– Apply the handbrake firmly.
– Engage the first gear , or put the selector lever to position P for
those vehicles with an automatic gearbox.
– If you are towing a trailer, unhitch it from your vehicle.
– Take the vehicle tools and the spare wheel out of the luggage
compartment.

WARNING
Switch on the hazard warning lights and place the warning triangles in
position. This is for your own safety and also warns other road users.
CAUTION
If you have to change the wheel on a slope, it is essential to lock the parallel
wheel on the same axle as that to be changed, with a wedge or similar in
order to immobilise the vehicle.
Note
Please observe legal requirements when doing so.
Changing a wheel
Change the wheel as described below
– Remove the hub caps or the integral trim .
– Slacken the wheel bolts .
– Raise the car with the jack at the corresponding point.
– Remove the wheel and then fit the spare wheel.
– Lower the vehicle.
– Tighten the wheel bolts firmly with the box spanner.
– Replace the hub cap. After changing a wheel
After changing the wheel there are still tasks to complete.
– Put the tools and jack back in the luggage compartment.
– Place the wheel with the defective tyre in the luggage compart-
ment and secure it.
– Check the tyre pressure of the newly fitted tyre as soon as pos-
sible.
– Have the tightening torque of the wheel bolts checked as soon
as possible with a torque wrench. The prescribed torque must
be 120 Nm.
Note
● If you notice that the wheel bolts are corroded and difficult to turn when
changing a wheel, they must be replaced before having the wheel bolt tor-
que checked.
● For safety reasons, drive at moderate speeds until the wheel bolt tight-
ening torque has been checked.

223
If and when
Note
● If sealant should leak out, leave it to dry. This way you can pull it off like
a piece of foil.
● Observe the expiry date stated on the sealing compound can. Have the
sealing compound exchanged by a specialised workshop.
● Seek professional assistance if the repair of a tyre puncture is not possi-
ble with the sealing compound.
What to do first
Certain steps must be taken before repairing a tyre.
– If you have a flat tyre or puncture, park the vehicle as far away
from the flow of traffic as possible.
– Apply the handbrake firmly.
– Engage first gear , or put the selector lever to position P.
– All passengers should leave the vehicle. They should wait in a
safe area (for instance behind the roadside crash barrier).
– Check whether a repair is possible using the Tyre Mobility Sys-
tem “General information and safety notes.”
– Unscrew inflation cap from the affected wheel.
– Take the tyre repair kit out of the luggage compartment.

● Bulbs are highly sensitive to pressure. The glass can break when you
touch the bulb, causing injury.
● The high voltage element of gas discharge bulbs* (xenon light) must
be handled correctly. Otherwise, there is a risk of death.
● When changing bulbs, please take care not to injure yourself on sharp
parts in the headlight housing.
CAUTION
● Remove the ignition key before working on the electric system. If not, a
short circuit could occur.
● Switch off the lights or parking lights before you change a bulb.

For the sake of the environment
Please ask your specialist retailer how to dispose of used bulbs in the prop-
er manner.
Note
● Depending on weather conditions (cold or wet), the front lights, the fog
lights, the tail lights and the turn signals may be temporarily misted. This
has no influence on the useful life of the lighting system. By switching on
the lights, the area through which the beam of light is projected will quickly
be demisted. However, the edges may continue to be misted.
● Please check at regular intervals that all lighting (especially the exterior
lighting) on your vehicle is functioning properly. This is not only in the inter-
est of your own safety, but also 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 va-
porise as a result of the heat generated by the bulb, they will be deposited
on the reflector and will impair its surface.
1)
With this type of headlight, the user can replace the indicator bulb. Replacement of the dip-
ped/main beam bulb must be done by a Technical Service, given that complex elements
must be removed from the vehicle and the automatic control system that incorporates it
must be reset.
2) The Xenon bulbs discharge 2.5 times the light flux and have an average lifespan of 5 times
more than that of halogen bulbs, this means that, except due to unusual circumstances,
there is no need to change the bulbs for the whole life of the vehicle.
3) In the event that there is a fault in the LEDs, the complete headlight must be replaced.

metal part bolted to the engine block or to the engine block it-
self ⇒ fig. 169.
6. Connect the other end of the black jump lead X
to a solid met-
al component bolted to the engine block or to the engine block
itself of the vehicle with the flat battery. Do not connect it to a
point near the battery A
.
7. Position the leads in such a way that they cannot come into contact with any moving parts in the engine compartment.
Starting
8. Start the engine of the vehicle with the boosting battery and let it run at idling speed.
9. Start the engine of the vehicle with the flat battery and wait one or two minutes until the engine is running.
Removing the jump leads
10. Before you remove the jump leads, switch off the headlights (if they are switched on). 11. Turn on the heater blower and heated rear window in the vehi-
cle with the flat battery. This helps minimise voltage peaks
which are generated when the leads are disconnected.
12. When the engine is running, disconnect the leads in reverse order to the details given above.
Connect the battery clamps so they have good metal-to-metal contact with
the battery terminals.
If the engine fails to start, switch off the starter after about 10 seconds and
try again after about half a minute.
WARNING
● Please note the safety warnings referring to working in the engine
compartment ⇒ page 194, Working in the engine compartment.
● The battery providing assistance must have the same voltage as the
flat battery (12V) and approximately the same capacity (see imprint on
battery). Failure to comply could result in an explosion.
● Never use jump leads when one of the batteries is frozen. Danger of
explosion! Even after the battery has thawed, battery acid could leak and
cause chemical burns. If a battery freezes, it should be replaced.
● Keep sparks, flames and lighted cigarettes away from batteries, dan-
ger of explosion. Failure to comply could result in an explosion.
● Observe the instructions provided by the manufacturer of the jump
leads.
● Do not connect the negative cable from the other vehicle directly to
the negative terminal of the flat battery. The gas emitted from the battery
could be ignited by sparks. Danger of explosion.
● Do not attach the negative cable from the other vehicle to parts of the
fuel system or to the brake line.

If and when
Towing and tow-starting
Tow-starting*
The use of jump leads is preferable to tow-starting.
We recommend that you do not tow-start your vehicle. Jump-start-
ing is preferable ⇒ page 240.
However, if your vehicle has to be tow-started:
– Engage the 2nd or the 3rd gear.
– Keep the clutch pressed down.
– Switch the ignition on.
– Once both vehicles are moving, release the clutch.
– As soon as the engine starts, press the clutch and move the
gear lever into neutral. This helps to prevent driving into the
towing vehicle.
WARNING
The risk of accidents is high when tow-starting. The vehicle being towed
can easily collide with the towing vehicle.
CAUTION
When tow-starting, fuel could enter the catalytic converter and damage it. Comments
Please observe the following points if you use a tow-rope:
Notes for the driver of the towing vehicle
–
Drive slowly at first until the tow-rope is taut. Then accelerate
gradually.
– Begin and change gears cautiously. If you are driving an auto-
matic vehicle, accelerate gently.
– Remember that the brake servo and power steering are not
working in the vehicle you are towing. Brake sooner than nor-
mal and pressing the pedal gently.
Notes for the driver of the towed vehicle
– Ensure that the tow-rope remains taut at all times when towing.
Tow-rope or tow-bar
It is easier and safer to tow a vehicle with a tow-bar. You should only use a
tow-rope if you do not have a tow-bar.
A tow-rope should be slightly elastic to reduce the loading on both vehicles.
It is advisable to use a tow-rope made of synthetic fibre or similarly elastic
material.
Attach the tow-rope or the tow-bar only to the towing eyes provided or a
towing bracket.
Driving style
Towing requires some experience, especially when using a tow-rope. Both
drivers should be familiar with the technique required for towing. Inexper-
ienced drivers should not attempt to tow.
