The rain sensor* automatically regulates the break between the individual
wiper strokes depending on the intensity of the rain.
Top up with wash liquid ⇒page 233.
WARNING
•Properly maintained windscreen wiper blades are essential for
clear visibility and safe driving ⇒page 67.
•Do not use the windscreen washer system at low temperatures,
without heating the windscreen beforehand. Otherwise the window
cleaner could freeze on the windscreen and restrict the view to the
front.
•The rain sensor only operates as a support. The driver is not
released from the responsibility to set the function of the wind-
screen wipers manually dependi ng on the visibility conditions.
Caution
In frosty weather, please first of all check whether the windscreen wiper
blades are not frozen to the windscreen before switching them on.
Switching on windscreen wipers when the blades are frozen to the wind-
screen may result in damage both to the blades and the motor of the wind-
screen wipers!
Headlight cleaning system*
The headlight lenses are cleaned, when low beam or main beam are
switched on by holding ⇒page 65 the lever for about 2 seconds in the
position .
The headlight washer nozzles are moved forward out of the bumper by the
water pressure for cleaning the headlights.
You should remove stubborn dirt (such as insect residues) from the head-
light lenses at regular intervals, for example when refuelling. Please refer
to the following guidelines ⇒page 209, “The headlight lenses”.
You should remove any snow from the fixtures of the washer nozzles and
clear ice in winter with a de-icing spray in order to ensure proper operation
of the cleaning system.

Driving and the Environment197
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
Avoid driving short distances
Short distances result in an above-average high fuel
consumption.
– Avoid driving a distance of no more than 4 km if the engine is
cold.
The engine and catalytic converter must first have reached their optimal
operating temperature in order to effectively reduce fuel consumption
and pollutant emissions.
The cold engine vehicle consumes approx. 20 - 30 litres/100 km of fuel
immediately after starting. Fuel consumption drops to 15 litres/100 km
after just 1 kilometre. The engine reaches its operating temperature
(outside temperature and engine dependent) only after about 4 to 10 kilo-
metres and the fuel consumption then stabilizes. You should therefore
avoid driving short distances whenever possible. An important factor in this connection is also the
ambient temperature.
The ⇒fig. 168 shows the different fuel consumptions for the same
distance, on the one hand at +20°C and on the other hand at -10°C. Your
vehicle has a higher fuel consumption in winter than in summer.
Checking tyre inflation pressures
Tyres which are correctly inflated save fuel.
Always ensure that your tyres are inflated to the correct pressure at all
times. The rolling resistance will be increased if the tyre filling pressure is
too low. This will not only increase fuel consumption but also tyre wear and
the driving behaviour will worsen.
Always check the inflation pressure of the tyres when cold.
Do not drive with winter tyres all year round for this costs about 10 %
more fuel. Winter tyres are also louder.
No unnecessary ballast
Transporting ballast costs fuel.
The fact that every kilogram of extra weight increases your fuel consump-
tion means that it is worth taking a look in the luggage compartment to
avoid transporting any unnecessary ballast.
It is particularly in town traffic, when one is accelerating quite often, that
the vehicle weight will have a significant effect upon the fuel consumption.
A rule of thumb here is that an increase in weight of 100 kilograms will
cause an increase in fuel consumption of about 1 litre/100 kilometres.
You may frequently also leave a roof rack fitted on just out of conven-
ience, although you no longer need it. The increased aerodynamic drag of

– Press the fuel tank flap closed.
The correct grade of fuel for your vehicle as well as the tyre size and infla-
tion pressures are stated on a sticker affixed to the inside of the fuel filler
flap. Further information on fuel ⇒page 214, “Fuel”.
The fuel tank has a capacity of about 62 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
immediately. This particularly applies to biodiesel - risk of paint damage!
•Vehicles fitted with catalytic converter should never be allowed to let
the fuel tank to 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.
For the sake of the environment
The fuel tank is full just as soon as the pump nozzle switches off for the
first time, provided the nozzle has been operated properly. You should not
continue refuelling - otherwise the expansion chamber in the fuel tank will
also be filled with fuel. Fuel might flow out of the tank when it heats up.
Emergency release of fuel filler flap
If the electric lock is faulty, you can also unlock the fuel filler flap
manually.
– Open the boot lid/luggage compartment door.
– Unscrew the clip attaching the right-hand side trim panel and
pull the trim panel off the body.
– Pull on the loop in direction of arrow in order to unlock the fuel filler flap ⇒fig. 171 .
WARNING
When unlocking the fuel filler flap manually, pay attention to sharp
edges of the body - risk of injury!

Wheels and Tyres
236
Tyre life
The 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 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 ⇒fig. 183 . The inflation pressures for winter tyres are
20 kPa (0.2 bar) higher than those for summer tyres ⇒page 240.
The tyre pressure should be at the highest pressure specified for your
vehicle at all times.
On cars with full wheel trim, valve extensions are fitted in place of dust
caps ⇒fig. 184 . It is not necessary to unscrew the valve extensions in
order to check and alter the inflation pressure of the tyre.
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 influ-
ences 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
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 indicators
The 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 indica-
tors are located at 6 - 8 points depending on the make and are evenly
spaced around the circumference of the tyre ⇒fig. 185 . 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.
WARNING
•You must have your tyres replaced with new ones at the latest
when the wear indicators have been worn down. The legally
permissible minimu m tread depth should be observed.
•Worn tyres do not provide the necessary adhesion to the road
surface at high speeds on wet roads. One could experience “aqua-
planing” (uncontrolled movements of the vehicle - “swimming” on
a wet road surface).

Spare wheel
The spare wheel is stowed in the spare wheel well in the
luggage compartment below the floor covering.
The spare wheel lies in a well in the luggage compartment under floor
covering and is fixed in place using special screws ⇒fig. 191 .
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 236) to ensure that the spare wheel is always ready to use.
Temporary spare wheel*
If you have such tyres on your vehicle, please refer to the notes below:
•The spare wheel provided with a car fitted with unidirectional tyres has
different dimensions. The wheel is provided with a warning sticker.
•After fitting on the wheel, the warning sticker must not be concealed
(e.g. by the wheel trim).
