Note
•If the slower or the faster wiper setting is switched on ⇒page 75,
fig. 55 and the vehicle speed decreases to below 4 km/h, the next lower
wiper step is switched on automatically. At a speed increase of more than
8 km/h the previous wiper setting is established again.
•If there is an obstacle on the windscreen, the wiper will try to push
away the obstacle. If the obstacle continues to block the wiper, the wiper
stops after 5 cycles, in order to avoid a damage to the wiper. Remove the
obstacle and and switch on the wiper again.
Headlight cleaning system*
The headlights are being cleaned after the windscreen has been sprayed
for the fifth time, the low beam or main beam are switched on and the
windscreen wiper lever was held in the position ⇒page 75, fig. 55 for
about 1 second.
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 237, “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.
Replacing wiper blades for the windscreen wipers
One cannot fold out the wiper arms in the rest position from the
windscreen. Before replacing the wiper arms you must put them
into the service position.
Service position for changing wiper blades

Automatic gearbox149
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
Automatic gearbox
6-speed automatic gearbox*
Introduction
Your car is equipped with an electronically controlled 6-speed automatic
gearbox. Shifting up and also down through the gears is performed auto-
matically.
At the same time this is a conventional automatic gearbox. The maximum
speed is reached in the 5th gear. The 6th gear serves as an economic
driving programme, which is intended to reduce the fuel consumption.
Information for driving wi th an automatic gearbox
Shifting up and down through the gears is performed auto-
matically.
You can also, however, switch the gearbox over into the
Tiptronic mode . This mode makes it possible for you to also shift
gears manually ⇒ page 153.
Starting-off and Driving
– Depress the brake pedal and hold it depressed.
– Press the Shiftlock button (button in handle of the selector lever), move the selector lever into the desired position, e.g. D
⇒ page 150, and then release the Shiftlock button. – Wait a moment until the gearbox has shifted (a slight engage-
ment nudge can be felt).
– Release the brake pedal and depress the accelerator ⇒.
Stopping for a short time
– The selector lever position N does not have to be selected
when stopping just for a short time, such as at cross roads. It
is sufficient to hold the vehicle stationary using the foot brake.
The engine can, however, be allowed just to idle.
Parking
– Depress the brake pedal and hold it depressed.
– Apply the handbrake firmly.
– Press and Shiftlock button in the selector lever, move the selector lever to P and then release the Shiftlock button.The engine can only be started when the selector lever is in position P or
N ⇒ page 140.
It is sufficient to engage selector lever position P when parking on a flat
surface. When parking on a slope you should first apply the handbrake
firmly and then move the selector lever into position P. This is to ensure
that there is no excessive pressure acting on the lock mechanism and that
it is easier to subsequently move the selector lever out of position P.
If the selector lever position N is selected by accident while driving it is first
necessary to release pressure on the accelerator pedal and wait for idling
speed of the engine to be reached before engaging a drive position in the
selector lever.

Driving and the Environment
226
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. 15 - 20 litres/100 km of fuel
immediately after starting. Fuel consumption drops to 10 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. 185 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
consumption means that it is worth taking a look in the luggage compart-
ment to avoid transporting any unnecessary ballast.
It is particularly in town trafffic, 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

Refuelling
The filler flap is automatically unlocked or locked* with the central
locking. Opening the fuel filler cap
– Press onto the left side of the fuel filler flap
⇒fig. 187 .
– The fuel filler cap on the fuel filler tube must be unlocked to the left using the vehicle key (only valid for vehicles which do not
have automatic unlocking of the fuel filler flap).
– Unscrew the fuel filler cap anti-clockwise and place the fuel filler cap from above on the fuel filler flap ⇒fig. 188 .
Closing fuel filler cap
– Screw on the cap by turning it to the right until it is heard to lock.
– The fuel filler cap on the fuel filler tube must be locked to the right using the vehicle key (only valid for vehicles which do not
have automatic locking of the fuel filler flap).
– 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 242, “Fuel”.
The fuel tank has a capacity of about 55 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.

Wheels and Tyres
264
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. 199 . The inflation pressures for winter tyres are
20 kPa (0.2 bar) higher than those for summer tyres ⇒page 268.
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 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.

After using the lifting jack, screw in the arm of the lifting jack fully before
placing it back in its stowage area.
WARNING
•The factory-supplied lifting jack is only intended for your model
of vehicle. On no account attempt to lift a heavier vehicle or other
loads - risk of injury!
•Ensure that the vehicle tool kit is safely attached in the luggage
compartment.
Note
Ensure that the box is always secured with the strap.
Tyre repair kit*
The tyre repair kit is intended for the repair of minor tyre defects. The tyre
repair kit contains a compressor, inflation bottle, operating instructions
and accessories.
The repair with the tyre repair kit is not at all intended to replace a
permanent repair on the tyre, this repair only serves to reach the next
specialist garage. The repair can be undertaken on the vehicle immedi-
ately. Please read the attached instructions carefully before the
repair.
The tyre repair kit is located in a well under the floor covering in the
luggage compartment.
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. 205 .
Before removing the spare wheel, you must take out the box with the
vehicle tool kit box ⇒page 274, fig. 204 .
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 264) 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 indi-
cates 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 sticker must not be concealed
(e.g. by the wheel trim).
