•
Never open the bonnet if you see that steam or coolant is flowing out of
the engine compartment - risk of scaldi
ng! Wait long enough until the steam
or coolant has stopped escaping.•
For safety reasons, the bonnet must always be properly closed when
driving. One should therefore check that
the lock has in fact engaged prop-
erly after closing the bonnet.•
Stop your vehicle immediately while driv
ing if you notice that the lock is
not properly engaged and close the bonne
t properly - risk of an accident!
Caution
Ensure that the arms of the windscreen
wipers are correctly
in place against the
windscreen before opening the bonnet otherwise damage could occur to the paintwork.Working in the engine compartment Particular care is required when carrying out any work in the engine compartment!There is a risk of injuries, scalding,
accidents and fire when working in the
engine compartment, e.g. inspecting and replenishing oil and other fluids. For this reason, it is essential to comply with the warning instructions stated below and with the general applicable
rules of safety. The engine compart-
ment of your car is a hazardous area
⇒
.
WARNING
•
Never open the bonnet if you see that steam or coolant is flowing out of
the engine compartment - risk of scaldi
ng! Wait long enough until the steam
or coolant has stopped escaping.•
Switch off the engine and pull out the ignition key.
•
Apply the handbrake firmly.
•
If your vehicle is fitted with a ma
nual gearbox, move the gearshift lever
into Neutral, or if it is fitted with
automatic gearbox, move the selector lever
into position P.•
Allow the engine to cool down.
•
Keep children clear of the engine compartment.
•
Never spill oil and other fluids over the hot engine. Such fluids (e.g. the
antifreeze contained in the coolant) may ignite!•
Avoid short circuits in the electrical system - particularly on the battery.
•
Never place your hand into the radiator fan as long as the engine is still
warm. The fan might suddenly start running!•
Never open the cap of the coolant expa
nsion bottle as long
as the engine
is still warm. The cooling system is pressurized!•
Cover over the cap of the coolant expansion reservoir with a large cloth
when opening it as protection for your
face, hands and arms from hot steam
or hot coolant.•
Do not let objects, such as e.g cleani
ng cloth or tools lie in the engine
compartment.•
If you wish to work under the vehicle, you must secure the vehicle from
rolling away and support it with suitable supporting blocks: the car jack is not sufficient for this - risk of injury!•
In cases where it be necessary to carry out inspection work when the
engine is running there is an additional risk from rotating parts (e.g. the V- ribbed belt, alternator, radiator fan) and from the high-voltage ignition system. Please observe in addition the following.
− Never touch the electrical cabl
es of the ignition system.
− Absolutely avoid any jewellery, loose items of clothing or long hair from getting into the rotating parts of the engine - Hazard! Therefore remove any jewellery beforehand, tie up your hair and wear tight fitting clothing.
•
Please also comply with the warnin
g instructions stated below when
carrying out any essential work on th

0.5 l/1 000 km depending on your style of
driving and the conditions under which
you operate your vehicle. Th
e oil consumption may be sl
ightly higher than this
during the first 5 000 kilometres. One should therefore check the oil level at regular intervals, preferably every time after the fuel tank is filled or after driving for long stretches. We recommend maintaining the oil level within the range -
but not above this

Wheels and TyresWheelsGeneral information•
New tyres do not offer optimal grip at first and should therefore be run in for
about 500 km at a moderate speed and an
appropriately cautious style of driving.
You will also profit from longer tyre life.•
The tread depth of new tyres may differ
because of design features and the
configuration of the tread (depending on
the type of tyre and the manufacturer).
•
Drive over curbs on the side of the road
and other such obstacles slowly and,
where possible, at a right angle in order to avoid damage to tyres and wheel trims.•
Inspect your tyres from time to time
for damage (punctures, cuts, splits and
bulges). Remove foreign bodies from the tyre profile.•
Damage to tyres and wheels is frequent
ly not visible. Unus
ual vibrations or
pulling of the vehicle to one side
could be a sign of tyre damage.
Please reduce
your speed immediately and stop if
you suspect that a wheel is damaged.
Inspect the tyres for signs of damage (bulges,
splits, etc.). If no
visible damage is
present, please drive at an appropriatel
y slow speed and carefully to the nearest
specialist garage in order to have your vehicle inspected.•
Also protect your tyres from contact with oil, grease and fuel.
•
Immediately replace any dust caps of the valves which have got lost.
•
Mark wheels before removing them so th
at their previous direction of running
can be maintained when mounted them again.•
Always store wheels or tyres which been removed in a cool, dry and, where
possible, dark place. Tyres which are not fixed to a wheel trim should be stored upright. Unidirectional tyres* The direction of rotation of the tyres is marked by arrows on the wall of the tyre. This indicates the direction of rotation of the tyre, and it is essential that the tyres are fitted on to run in this direction. Only then
are the tyres able to provide the optimal
properties in terms of grip, low noise, wear-and-tear and aquaplaning.
Further information concerning
the use of unidi
rectional tyres
⇒page 239.
WARNING
•
New tyres during the first 500 km do not offer optimal grip and should
therefore be run appropriately - risk of accident!•
Never drive with damaged tyres - risk of accident!Note
Please observe the various differing legal requirements regarding tyres.Tyre lifeThe life of your tyres very much depends on the following points: Tyre pressure The working life of tyres will be shortened considerably if the tyres are insufficiently or over-inflated and this will have an advers
e effect on the handli
ng of your vehicle.
Correctly inflated tyres are of partic
ular importance when travelling at
high speeds
.
It is therefore good to check the pressure at least once a month and also before

setting off on a long trip. Please do not forget the spare wheel when checking the tyres. The tyre inflation pressures for
summer tyres
are indicated on the inside of the fuel
filler flap
⇒page 235, fig. 210
. The inflation pressures for
winter tyres
are 20 kPa
(0.2 bar) higher than those for summer tyres
⇒page 239.
The tyre pressure should be at the highest pressure specified for your vehicle at all times. The tyre inflation pressure of the emergency spare wheel R 18 is 420 kPa (4.2 bar).Always check the inflation pressure of ty
res when cold. Do not reduce the higher
pressure of warm tyres. Adapt the inflation pressure of the tyres accordingly if your vehicle is carrying a significantly higher payload. Driving style Fast cornering, sharp acceleration and braking (squealing tyres) increase wear-and- tear on your tyres. Balancing wheels The wheels of a new vehicle are balanced. There are a wide range of influences when driving which may result in an imbalance and which makes themselves felt through vibration in the steering. You should have the wheels rebalanced
since any imbalance increases wear-and-
tear on the steering, the suspension and
tyres. A wheel must also be rebalanced
when a new tyre is fitted and each time a tyre is repaired. Wheel alignment errors Incorrect wheel alignment at the front and re
ar will not only increase wear-and-tear
on the tyres but will also has an adverse
effect on vehicle safety. Contact your
specialist garage if you notice any unusual tyre wear.
WARNING
•
If the inflation pressure is too low,
the tyre must perform a greater flexing
work. At higher speeds the tyre will warm up as a result of this. This can result in tread separation and even a tyre blowout.•
Immediately replace the damaged rims or tyres.
For the sake of the environment
Tyres which are insufficiently inflated increase your fuel consumption.Wear indicatorsThe base of the tread of the original tyres has wear indicators 1.6 mm high, installed at right angles to the direction of travel. These wear indicators are located at 6 - 8 points depending on the make and are evenly spaced around the circumference of the tyre
⇒fig. 211
. Markings on the walls of the
tyres through the letters “TWI”,
triangular symbols or other symbols identi
fy the position of the wear indicators.
A remaining tread of just 1.6 mm, measured in the grooves of the tread next to the wear indicators, means that your tyres
have reached their legally permissible
minimum tread depth.
WARNING
•
You must have your tyres replaced with new ones at the latest when the
wear indicators have been worn do
wn. The legally permissible minimum
tread depth should be observed.•
Worn tyres do not provide the necessar
y adhesion to the road surface at
high speeds on wet roads. One coul
d experience “aquaplaning” (uncon-
trolled movements of the vehicle - “swimming” on a wet road surface).

Technical Data
Winter tyresThe handling of your vehicle will be significantly improved when driving on wintry roads if you fit winter tyres. Summer tyres do not offer the same grip on ice, snow and at temperatures below 7 °C because of
their construction (width, rubber blend,
tread pattern). This partic
ularly applies to vehicles
which are equipped with
low-
profile tyres
or high-speed tyres
(code index H or V on wall of tyre).
Winter tyres must be mounted on all four wheels to obtain the best handling char- acteristics. You must only fit those types of winter tyre which are approved for your vehicle. The permissible
sizes of winter tyres
are stated in your vehicle documents. Approvals
may differ because of national legislation. Please remember that the tyres should be in
flated to 20 kPa (0.2 bar) more than is
the case for summer tyres
⇒page 235, fig. 210
.
Winter tyres no longer
offer the same winter performance once the
tyre tread
has
worn down to a depth of about 4 mm. Ageing
also causes winter tyres to lose most of their winter performance properties
- even in cases where the remaining tread depth is still clearly more than 4 mm. Speed restrictions
apply to winter tyres as well as to summer tyres
⇒page 237,
⇒
.
You can fit winter tyres of a lower speed ca
tegory to your vehicle provided that you
also do not drive faster than the permis
sible maximum speed fo
r such tyres, even
if the possible maximum speed of your ve
hicle is higher. The corresponding tyre
category can damage the tyres when ex
ceeding the permissi
ble maximum speed.
Please pay attention to the notes if
you decide to fit winter tyres
⇒page 235.
You can also fit so-called “all-year tyres” instead of winter tyres.Please contact your specialist garage if
there are any points which are not clear who
will be able to provide you with information regarding the maximum speed for your tyres.
WARNING
You must on no account drive your car at more than the permissible maximum speed for your winter tyres - risk of an accident resulting from tyre damage and loss of control over your car.
For the sake of the environment
Fit your summer tyres on again in good ti
me since summer tyres offer you better
grip and handling on roads which are free of snow and ice as well as ar tempera-tures below 7 °C - the braking distance is shorter, there is less tyre noise, tyre wear is reduced and fuel consumption is reduced.
Note
Please observe the various differing legal requirements regarding tyres.Unidirectional tyres*The direction of rotation of the tyres is marked by
arrows on the wall of the tyre
.
This indicates the direction of rotation of the tyre, and it is essential that the tyres are fitted on to run in this direction. Only then are the tyres able to provide the optimal properties in terms of grip, low noise, wear-and-tear and aquaplaning. Should it be necessary to fit on a spare
wheel in exceptional cases with a tyre not
dedicated to the running dire
ction or in opposite running
direction, please adopt a
cautious style of driving as the tyre is no
longer able to provide optimal grip and
handling in such a situation.
This particularly important
on wet roads. Please refer
to the notes
⇒page 245, “Spare wheel*”.
You should have the defective tyre replac
ed as soon as possible and restore the
correct direction of rotation on all tyresSnow chainsSnow chains must only be mounted on the front wheels.

Spare wheel*The spare wheel lies in a well under the floor covering of the luggage compartment and is fixed in place using special screws
⇒fig. 216
.
Before removing the spare wheel, you must take out the box with the vehicle tool kit box
⇒page 244, fig. 215
.
One should check the inflation pressure in the spare wheel (at best when generally checking the tyre air pressures - see sign on the fuel filler flap
⇒page 235) to
ensure that the spare wheel is always ready to use. Temporary spare wheel A warning label displayed on the rim of the temporary spare wheel indicates that your vehicle is equipped with a temporary spare wheel. Please observe the following notes when driving with a temporary spare wheel:•
After fitting on the wheel, the warning stic
ker must not be concealed (e.g. by the
wheel trim).•
Do not drive with this spare wheel at more than 80 km/h - risk of accident. Avoid
accelerating at full throttle, sharp braking and fast cornering.•
The inflation pressure for this spare wheel is identical to the inflation pressure
of the standard tyres. The temporary spare wheel R 18 must have an inflation pres-sure of 420 kPa (4.2 bar)!
•
Use this spare wheel only to reach the nearest specialist garage as it is not
intended for continuous use.•
No other summer or winter tyres must
be mounted on the rim of the spare
wheel R 18.Changing a wheelPreliminary workThe following steps should be carried out before actually changing the wheel. – If it is necessary to change a wheel, park the vehicle as far away as
possible from the traffic flow. The place you choose should be
level
.
–Have
all the occupants get out.
While changing a wheel, the occu-
pants of the vehicle should not stan
d on the road (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
