Fuel 182Operation in winterWinter-grade diesel fuel
A different grade of diesel fuel is available at filling stations in winter than during the
summer. Using “summer-grade diesel fuel” at temperatures below 0°C can result in
operational problems because the diesel becomes viscous as a result of paraffin
separation.
It is therefore the case that EN 590 prescribes diesel fuel class for certain periods of
the year which can also be purchased at the corresponding time during the year.
“Winter-grade diesel fuel” will still operate properly even at a temperature of -20°C.
It is often the case in countries with different climatic conditions that diesel fuels
available have a different temperature characteristic. The specialist garages and the
filling stations in the country concerned will be able to provide you with informa-
tion regarding the diesel fuels available.
Prewarming fuel
The vehicle is fitted with a fuel filter prewarming system. This secures operation of
a vehicle using diesel fuel down to an environmental temperature of -25°C.
Caution
It is not permitted to add the various fuel additives on the market, including petrol,
to diesel fuel in order to improve its flow properties.

– Lock the fuel filler cap on the fuel filler tube by turning the vehicle key
to the right and withdraw the key.
– Press the fuel tank flap closed.The correct grades of fuel for your vehicle are stated on a sticker affixed to the inside
of the fuel filler flap. Further information on fuel ⇒page 181.
The fuel tank has a capacity of about 45 litres.
WARNING
Pay attention to any legal requirements if you do carry a spare canister in the
vehicle. We do not recommend carrying any fuel canisters in your vehicle for
safety reasons. The canister can be damaged in the event of an accident and
fuel may leak out.
Caution
•
Remove any fuel which has spilled onto the paintwork of your vehicle immedi-
ately - risk of paint damage!
•
On vehicles fitted with a catalytic converter, never let the fuel tank run
completely empty. An irregular supply of fuel to the engine can result in misfiring
and unburnt fuel may get into the exhaust system, which may result in overheating
and damage to the catalytic converter.
•
Make sure that the valve is not pressed into the filler tube when inserting the
pump nozzle into the filler tube. Otherwise you are unintentionally filling up the
volume, which in case of heat can cause an expansion of the fuel. This can lead to
an overflow of fuel or damage to parts of the fuel reservoir.
•
T h e f u e l t a n k i s f u l l j u s t a s s o o n a s t he pump nozzle switches off for the first time,
provided the nozzle has been operated properly. Do not continue refuelling -
otherwise the expansion volume is filled up.

Inspecting and replenishing 186•
Do not let objects, such as e.g cleaning 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 cables 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 warning instructions stated below when
carrying out any essential work on the fuel system or on the electrical
system:
−Always separate the car battery from the electrical system.
−Do not smoke.
−Never carry out any work close to naked flames.
−Always keep a working fire extinguisher at hand.Caution
When replenishing fluids in the engine, always ensure that the fluids are on no
account mixed up. This may result in major operating problems and also vehicle
damage!

Engine oilCheck engine oil level
The dipstick indicates the level of oil in the engine.Checking the oil level
– Ensure that the vehicle is positioned on a level surface.
– Switch the engine off.
– Open the bonnet ⇒ in “Working in the engine compartment” on
page 185.
– Wait a few minutes and pull out the oil dipstick ⇒.
– Wipe off the dipstick with a clean cloth and insert it again fully.
– Then withdraw the dipstick again and read off the oil level.
Oil level within range
– You must not top up the oil.Oil level within range
–You may top up the oil. It is possible that the oil level may then be
within range after doing this.
Oil level within range
–You must top up the oil. It is ideal, once this is done, to keep the oil
level within range .
It is normal for the engine to consume oil. The oil consumption may be as much as
0.5 l/1 000 km depending on your style of driving and the conditions under which
you operate your vehicle. The oil consumption may be slightly 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 if the engine has been
operating at high loads, for example during a lengthy motorway trip during the
summer months, towing a trailer or negotiating a high mountain pass, but not
above this.
The warning light in the instrument cluster* will indicate ⇒page 30 whether the oil
level is too low. In this case, check the oil level as soon as possible. Top up with an
appropriate quantity of oil.
WARNING
Read and observe the warning notes ⇒page 185, “Working in the engine
compartment” before working in the engine compartment.
Caution
•
Always check the oil level on vehicles with engine 1.2 l/44 kW when the engine
is cold. On other vehicles when the engine is warm. Otherwise the measuring result
is incorrect und oil could be incorrectly replenished - risk of engine damage!
•
The oil level must on no account extend beyond the range . Danger of
damaging the catalytic converter.

Wheels and Tyres 198Wheels 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 frequently not visible. Unusual 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 appropriately 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 that 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 unidirectional tyres ⇒page 202.
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 adverse effect on the handling of your vehicle.
Correctly inflated tyres are of particular importance when travelling at high speeds.
It is therefore good to check the pressure at least once a month and also before

Technical Data 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 198, fig. 190. The inflation pressures for winter tyres are 20 kPa
(0.2 bar) higher than those for summer tyres ⇒page 202.
The tyre pressure should be at the highest pressure specified for your vehicle at all
times.
Always check the inflation pressure of tyres 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 rear 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 higher rolling
resistance. 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.
•
Tyres which are 6 years old or more should only be fitted in exceptional
cases and when adopting an appropriately cautious style of driving.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. 191. Markings on the walls of the tyres through the letters “TWI”,
triangular symbols or other symbols identify 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.

Wheels and Tyres 202Winter 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 applies in particular to vehicles which are equipped with low-
profile tyres or high-speed tyres (code index H, V or W 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 inflated to 20 kPa (0.2 bar) more than is
the case for summer tyres ⇒page 198.
Winter tyres no longer offer the same winter performance once the tyre tread has
worn down to a depth of about 4 mm.
Ageing a l s o c a u s e s w i n t e r t y re s t o l o s e m o s t 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 200,
⇒.
You can fit winter tyres of a lower speed category to your vehicle provided that you
also do not drive faster than the permissible maximum speed for such tyres, even
if the possible maximum speed of your vehicle is higher. The corresponding tyre
category can damage the tyres when exceeding the permissible maximum speed.
Please pay attention to the notes if you decide to fit winter tyres ⇒page 198.
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 time 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 the event of a puncture with a tyre
not dedicated to the running direction 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 206, “Spare wheel*”.
You should have the defective tyre replaced as soon as possible and restore the
correct direction of rotation on all tyresSnow chainsSnow chains must only be mounted on the front wheels.
