Headlight cleaning system*
The headlight lenses are clea ned, when low beam or main beam are switched on
by holding ⇒page 53 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 headlight
lenses at regular intervals, for example when refuelling. Please refer to the following
guidelines ⇒page 176, “The headlight lenses”.
You should remove any snow from the fixt ures 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 the wiper blades
Taking off the wiper blade
– Fold windscreen wiper arm out from the windscreen and position the
wiper blade at right angles to the wiper arm ⇒fig. 50 .
– Press the securing spring in the direction of arrow and press the wiper blade to the windscreen at the same time in the direction of
arrow ⇒.
Attaching a wiper blade
– Push the wiper blade onto the wiper arm. The securing spring must click into place audibly.
Wiper blades in proper condition are esse ntial to obtain good visibility. Wiper
blades should not be allowed to become dirtied by dust, insect remains and
preserving wax.
Juddering or smearing of the wiper blades could then be due to wax residues left
on the windscreen by vehicle washing in automatic vehicle wash systems. It is
therefore important to degrease the lips of the wiper blades after every pass
through an automatic vehicle wash system .

Starting-off and Driving101
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
Starting the engine
General
You can only start the engine only using an original ignition key.
•Place the gearshift lever into neutral (or place the selector lever to the position
P or N in the case of an automatic gearbox) and put on the handbrake firmly before
starting the engine.
•The clutch pedal should be fully depressed when starting the engine which
means that the starter only has to crank the engine.
•Let go of the key as soon as the engine starts otherwise there may be damage
to the starter.
The engine running noises may louder at first be louder for a short time after
starting the cold engine until oil pressure can be built up in the hydraulic valve
clearance compensation. This is quite normal and is not an operating problem.
If the engine does not start ...
You can use the battery of anothe r vehicle as a jump-start aid ⇒page 215.
It is only possible to tow-start vehicl es fitted with a manual gearbox. The tow-
starting distance must not be more than 50 metres ⇒page 217.
WARNING
•Never run the engine in non ventilat ed or enclosed areas. The exhaust
gases of the engine contain besides the odorless and colourless carbon
monoxide a poisonous gas - hazard! Carbon monoxide can cause uncon-
sciousness and death.
•Never leave your vehicle unattended with the engine running.
Caution
•The starter may only be operated (ignition key position ), if the engine is not
running. If the starter is immediately oper ated after switching off the engine, the
starter or the engine can be damaged.
•Avoid high engine revolutions, full throttle and high engine loads as long as the
engine has not yet reached it s normal operating temperature - risk of damaging the
engine!
•Vehicles which are fitted wi th an exhaust gas catalytic converter should not be
tow-started over a distance of more than 50 metres.
For the sake of the environment
Never warm up the engine when the vehicle is standing. Drive off right away.
Through this the engine reaches its operating temperature more rapidly and the
pollutant emissions are lower.
Petrol engines
These engines are fitted with a starter system which selects the correct fuel/air
mixture for every external air temperature.
•Do not operate accelerator before and when starting engine.
•Interrupt the attempt at starting after 10 seconds if the engine does not start
right awayand wait for about 30 seconds before repeating the attempt.
•It is possible that the fuse on the electric al fuel pump is defect if the engine still
does not start. Check the fuse and replace it if necessary ⇒page 220.
•If the engine does not start, contact th e nearest specialist garage to obtain
professional assistance.
It may be necessary, if the engine is very hot, to slightly depress the accelerator
after the engine has started.
Diesel engines
Glow plug system
Diesel engines are equipped with a glow plug system, the preglow period being
controlled automatically in line with the coolant temperature and outside temper-
ature.
The preglow indicator light
 comes on after the ignition has been switched on.

Automatic gearbox*
112
Shiftlock button
The Shiftlock button in the handle of select or lever prevents certain selector lever
positions being engaged inadvertently. The selector lever lock is cancelled when
you press the Shiftlock button.
Keylock - Ignition key withdrawal lock
You can only withdraw the ignition key after switching off the ignition if the selector
lever is in position P. If the ignition key is withdrawn, the selector lever is blocked in
position P.
Kickdown function
The kickdown function provides you with maximum acceleration
power.
Depressing the accelerator pedal beyond the pressure point casues the automatic
gearbox to shift down into a lower gear (in line with vehicle speed and engine
speed). The gearbox shifts up into the next higher gear when the engine has
reached its maximum revolutions.
WARNING
Please note that using the kickdown fu nction can result in the driven wheels
spinning on a smooth or slippery road surface - risk of skidding!
Dynamic shift programme
The automatic gearbox of your vehicle is controlled electronically. Shifting up and
down through the gears is performed auto matically on the basis of pre-defined
driving programmes.
Adopting a moderate style of driving will cause the gearbox to select the most
economical driving programme. Shifting up into a higher gear as soon as possible
and shifting down as late as possible will have a favourable effect on your fuel
consumption. Adopting a
faster style of driving with rapid movements of the accelerator pedal
combined with sharp acceleration and freq uent changes in speed, exploiting the
top speed of the car or operating the kick down function, will cause the gearbox to
switch over to the sporty driving programme. Shifting up later into a higher gear
makes it possible to fully exploit the powe r reserves of the engine. The gearbox also
then shifts down at higher engine speeds than is the case for the economy-oriented
programmes.
Selecting the most appropriate driving programme for the particular style of driving
is a continuous process. Irrespective of this it is, however, possible to switch into a
sporty driving programme by depressing the accelerator rapidly. The gearbox shifts
down into a lower gear matching the speed of the car and this allows you to accel-
erate rapidly (e.g. when overtaking) without having to depress the accelerator pedal
fully into the kickdown range. The original programme will be reactivated to match
your particular style of driving once the gearbox has shifted up again.
When driving in hilly regions, the gears are selected to match uphill and downhill
sections. This avoids the gearbox frequently shifting up and down when negotiating
an uphill stretch. Depressing the brake pedal while driving downhill causes the
gearbox to shift down into the next lower gear. This makes it possible for you to
exploit the engine braking power withou t the need for shifting gears manually.

pedal firmly and hold it in this position in order to achieve the shortest possible
braking distance.
The Brake Assist is able to help you achieve a shorter braking distance in emergency
situations by rapidly producing the pressure required in the brake system. It fully
exploits the attributes of the ABS. After you release the brake pedal, the function of
the Brake Assist is automatically switched off and the brakes operate in the normal
way.
WARNING
•The Brake Assist is also not able to overcome the physical limits of your
car in terms of the braking distance required.
•Adapt your speed to the conditions of the road surface and to the traffic
situation.
•The increased safety offered by the Brake Assist must not tempt you to
take a greater safety risk than otherwise.
Power steering
Power steering assists the driver in steering the vehicle and reduces the physical
force needed for steering.
The steering characteristics can be changed by a specialist garage.
It is still possible to fully steer the vehicle if the power steering fails or if the engine
is not running (vehicle being towed in). The only difference is that greater physical
effort is required.
If the steering is turned to full lock when the car is stationary, you will place great
stresses on the power steering system. Turning the steering to full lock in such a
situation will be accompanied by noises. In addition, the idling speed of the engine
will drop briefly.
Caution
Do not leave the steering at full lock for more than 15 seconds when the engine is
running - risk of damagi ng the power steering!
Note
•Have the steering inspected as soon as po ssible by a specialist garage if there is
a leak or fault in the system.
•The power steering requires a special hydraulic oil. The oil reservoir is located
at the front left of the engine compartment ⇒page 186. The correct hydraulic oil
level is important for proper oper ation of the power steering system.
Diesel particle filter* (diesel engine)
In the diesel particle filter the resulting soot particles are collected
and burnt during the combustion of diesel fuel.
Code 7GG on the vehicle data sticker ⇒fig. 165 indicates that your
vehicle is equipped with a diesel particle filter. The vehicle data sticker is
located on the floor of the luggage com partment and is also stated in the
Service schedule.
The diesel particle filter filters the soot particles completely from the exhaust. The
soot is collected in the diesel particle filter and burnt regularly. To assist this proce-
dure, we recommend not to drive regularly over short distances.

Driving and the Environment
162
Driving and the Environment
The first 1 500 kilometres and then afterwards
A new engine
The engine has to be run in du ring the first 1 500 kilometres.
Up to 1 000 kilometres
– Do not drive faster than 3/4 of the mamimum speed of the gear in use,
that is 3/4 of the maximum permissible engine speed.
– Do not use full throttle.
– Avoid high engine revolutions.
– Do not tow a trailer.
From 1 000 up to 1 500 kilometres
– Increase the power output of the engine gradually up to the full
speed of the gear enga ged, that is up to the maximum permissible
engine revolutions.
During the first operating hours the engine has higher internal friction than later
until all of the moving parts have harm onized. The driving style which you adopt
during the first 1 500 kilometres plays a de cisive part in the success of running in
your car.
You should not drive at unnecessarily high engine revolutions even after the
running-in period is comple te. The maximum permissible engine speed is marked
by the beginning of the red zone on the scale of the revolutions counter. Shift up
into the next higher gear on a vehicle fitted with manual gearbox before the red
zone is reached. Extremely high engine revolutions are automatically governed, by
the way.
For a vehicle fitted with a manual gearbox the converse situation also applies: Do
not drive at engine revolutions which are too low. Shift down as soon as the engine
is no longer running smoothly.
Caution
All the speed and engine revolution figures apply only when the engine is at its
normal operating temperature. Never rev up an engine which is cold, neither when
the vehicle is stationary nor when driving in individual gears.
For the sake of the environment
Not driving at unnecessarily high engine revolutions and shifting to a higher gear as
early as possible are ways to minimise fuel consumption and operating noise levels
and protects the environment.
New tyres
New tyres have to be “run in” since they do not offer optimal grip at first. You should
take account of this fact for the first 500 kilometres and drive particularly carefully.
New brake pads
Allow for the fact that new brake pads do not achieve their full braking efficiency
until approximately 200 kilometres. New brak e pads must be first “run in” before
they develop their optimal friction force. You can, however, compensate for this
slightly reduced braking force by increasing the pressure on the brake pedal.
This guideline also applies to any new brake pads installed at a future date.
During the running-in period , you should avoid excessive stresses on the brakes.
This includes, for example, violent braking, particularly from very high speeds, and
also when crossing mountain passes.

Driving and the Environment

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 mu st first have reached their optimal operating
temperature in order to effectively reduce fu el consumption and pollutant emis-
sions.
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 temperat ure (outside temperature and engine
dependent) only after about 4 to 10 kilometres 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 consumption
means that it is worth taking a look in the luggage compartment to avoid trans-
porting any unnecessary ballast.
It i s par ti cula rl y in town traff ic, when one i s accel era ti ng qui te often, tha t the v ehicle
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 convenience,
although you no longer need it. The incr eased aerodynamic drag of your vehicle
causes it to use about 1 l more fuel than normal at a speed of 100 - 120 km/h, even
when you are not carrying a load on the roof.
Saving electricity
Gen era ti n g e l ect r icity costs fuel.
– Switch off electrical components as soon as you no longer need them.
When the engine is running, the alternator generates and supplies electrical power.
The greater the load on the alternator as a result of having a large number of elec-
trical components switched on, the more fuel will be consumed for operating the
alternator.

Wheels and Tyres
200
Ty re l i fe
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 advers e 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 203.
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 nece ssary to unscrew the valve extensions in order to check and
alter the inflation pressure of the tyre.
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 signi ficantly higher payload.
Driving style
Fast cornering, sharp acceleration and brak ing (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 no tice 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.

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 200) 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 st icker must not be concealed (e.g. by the

•The inflation pressure for this spare wheel is identical to the inflation pressure
of the standard tyres.
•Use this spare wheel only to reach the nearest specialist garage as it is not
intended for continuous use.
Changing a wheel
Preliminary work
The 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.
– If a trailer is coupled, uncouple it.
– Take the vehicle tool kit and the spare wheel ⇒ page 209 out of the
luggage compartment.
