Driving and the environment
182your vehicle has automatic transmission). This makes use of engine
braking and relieves the brakes.•
Never let the brakes “slip” by applying light pressure. Continuous
braking will cause the brakes to overheat and the braking distance will
increase. Apply and then release the brakes alternately.
•
Never let the vehicle run with the engine switched off. The braking
distance is increased considerably when the brake servo is not active.
•
Very heavy use of the brakes may cause a vapour lock if the brake fluid
is left in the system for too long. This impairs the braking effect.
•
Non-standard or damaged front spoilers could restrict the airflow to the
brakes and cause them to overheat. Observe the relevant instructions
before purchasing accessories ⇒ page 206, “Technical modifications”.
•
If a brake circuit fails, the braking distance will be increased consider-
ably. Contact a qualified workshop immediately and avoid unnecessary
journeys.
Exhaust gas purification systemCatalytic converter*To conserve the useful life of the catalytic converter
– Always use unleaded petrol.
– Do not let the fuel get too low in the tank.
– For engine oil changes, do not replenish with too much engine oil ⇒page 215. – Never tow the vehicle to start it, use jump leads if necessary
⇒page 271.
If you notice misfiring, uneven running or loss of power when the vehicle is
moving, reduce speed immediately and have the vehicle inspected at the
nearest qualified workshop. In general, the exhaust warning lamp will light
up when any of the described symptoms occur ⇒page 66. If this happens,
unburnt fuel can enter the exhaust system and escape into the environment.
The catalytic converter can also be damaged by overheating.
WARNING
The catalytic converter reaches very high temperatures! Fire hazard!•
Never park where the catalytic convert er could come into contact with
dry grass or inflammable materials under the vehicle.
•
Do not apply additional underseal or anti-corrosion coatings to the
exhaust pipes, catalytic converter or the heat shields on the exhaust
system. These materials could catch fire when the vehicle is being driven.Caution
Never fully drain the fuel tank because the irregularity of the fuel supply may
cause ignition problems. This allows unburnt fuel to enter the exhaust
system, which could cause overheating and damage the catalytic converter.
For the sake of the environment
Even when the emission control system is working perfectly, there may be a
smell of sulphur from the exhaust under some conditions. This depends on
the sulphur content of the fuel used. Quite often the problem can be solved
by changing to another fuel brand.

Your vehicle maintenance and cleaningGeneral notesRegular washing and care help maintain the value of your
vehicle.Your vehicle maintenance
Regular care and washing help to maintain the value of the vehicle. This may
also be one of the requirements for acknowledging warranty claims in the
event of bodywork corr osion or paint defects.
The best way to protect your car against the harmful effects of the environ-
ment is through correct maintenance and frequent washing. The longer
substances such as insects remains, bird droppings, resinous tree sap, road
dirt, industrial deposits, tar, soot or road salt and other aggressive materials
remain on the vehicle, the more damage they do to the paintwork. High
temperatures (for instance in strong sunlight) further intensify the corrosive
effect.
After winter, a period when salt is put on the roads, it is important to have the
underside of the vehicle washed thoroughly.
Products for vehicle maintenance
Car care products are available in your Authorised Service Centre. Keep the
product instructions until you have used them up.
WARNING
•
Car care products can be toxic. For this, they must always be kept
closed in their original container. Keep them out of the reach of children.
Failure to comply could result in poisoning.
•
Always read and observe the instructions and warnings on the package
before using car care products. Improper use could damage your health or your vehicle. The use of certain products may produce noxious vapours;
they should be used in well ventilated areas.
•
Never use fuel, turpentine, engine oil, nail varnish remover or other
volatile fluids. These are toxic and highly flammable. Risk of fire and explo-
sion.
•
Before washing your vehicle, or carrying out any maintenance, switch
the engine off, apply your handbrake firmly and remove the key from the
ignition.Caution
Never attempt to remove dirt, mud or dust if the surface of the vehicle is dry.
Never use a dry cloth or sponge for clea ning purposes. This could damage the
paintwork or the windows of your vehicle. Soak dirt, mud or dust with plenty
of water.
For the sake of the environment
•
When purchasing products for your vehicle maintenance, select the ones
which are not harmful to the environment.
•
The leftovers of the car care products should not be disposed of with ordi-
nary household waste. Observe the disposal information on the package.WARNING (continued)

•
Remove the ignition key.
•
Apply handbrake firmly.
•
Place the gear lever into neutral.
•
Wait for the engine to cool down.
•
Children should not be allowed to approach the engine compartment
•
Never spill liquids involved in vehicle operations on the engine
compartment, as these may catch fire (e.g. anti-freeze containing liquid
coolant).
•
Take care not to cause short circuits in the electrical system, especially
when working on the battery.
•
Never touch the radiator fan while the engine is hot, as the fan could
start up suddenly.
•
Never open the expansion tank when the engine is hot. The cooling
system is under pressure.
•
Protect face, hands and arms from any hot steam or hot liquid coolant
released by covering the cap with a large, thick rag when opening the
expansion tank.
•
If any tests have to be performed with the engine running, there is an
extra safety risk from the rotating parts, such as the drive belts, alternator
and radiator fan, etc., and from the high-voltage ignition system.
•
Observe the following additional warnings if work on the fuel system or
the electrical system is necessary:
−Always disconnect the battery.
− Do not smoke.
− Never work near open flames
− Always keep an approved fire extinguisher immediately available.Caution
When topping up fluids, make sure the correct fluid is put into the correct
filler opening. This can otherwise cau se serious malfunctions or engine
damage.
For the sake of the environment
Inspect the ground underneath your vehicle regularly so that any leaks are
detected at an early stage. If you find spots of oil or other fluids, have your
vehicle inspected in the garage.

222•
To prevent smearing on the windscreen, the wiper blades should be
cleaned regularly using a window cleaner solution. If the wiper blades are
very dirty (e.g. insects etc.), they should be cleaned using a sponge or
cloth. Failure to do so co uld result in an accident.
•
For safety reasons, the wiper blades should be changed once or twice a
year.Caution
•
Damaged or dirty windscreen wipers could scratch the windscreen.
•
Never use fuel, nail varnish remover, paint thinner or similar products to
clean the windows. This could damage the windscreen wiper blades.
•
Never move the windscreen wiper or windscreen wiper arm manually. This
could cause damage.
•
Do not pull the windscreen wipers forward unless they are in the service
position. Otherwise the bonnet could be damaged.Note
•
The wiper arms can be moved to the service position only when the
bonnet is properly closed.
Brake fluidChecking the brake fluid level
The brake fluid level can be checked at a glance.The brake fluid level must be between the “Min” and “Max” ⇒fig. 171 mark-
ings.
The fluid level may drop slightly after a period of time due to the automatic
compensation for brake pad wear. This is quite normal.
However, if the level goes down noticeably in a short time, or drops below the
“Min” mark, there may be a leak in the brake system. If the fluid level in the
reservoir is too low, this will be indicated by the brake warning lamp
⇒ page 70 and ⇒ page 77. If this should happen, take the car to a qualified
workshop immediately and have the brake system inspected.

Topping up and changing the brake fluid
It is best to have the brake fluid changed by a professional.Brake fluid absorbs damp. Therefore, in the course of time it will absorb water
from the ambient air. If the water content in the brake fluid is too high, the
brake system could corrode. In addition, the boiling point of the brake fluid
will be considerably reduced. This could adversely affect the braking ability in
certain circumstances.
For this reason the brake fluid must be changed periodically.
Your vehicle's Service Schedule will tell you when the brake fluid has to be
renewed.
We recommend you have the brake fluid changed as part of a regular Inspec-
tion Service at your garage. They are familiar with the procedure and have the
necessary special tools and spare parts as well as the proper facilities for
disposing of the old fluid.
Use only the genuine brake fluid specified by the factory Specialist garages
know that the brake fluid -DOT 4- is factory approved. The brake fluid must be
new.
WARNING
•
Therefore, it must always be kept closed in its original container. Keep
out of the reach of children. Failure to comply could result in poisoning.
•
Heavy use of the brakes may cause a vapour lock if the brake fluid is left
in the system for too long. This would seriously affect the efficiency of the
brakes and the safety of the car, leading to the risk of accident.Caution
Please note that brake fluid will attack the paintwork on contact.
For the sake of the environment
If the fluid has to be drained out of the brake system, use an appropriate
container to catch the used brake fluid and dispose of it in the proper
manner.BatteryGeneral notes
All work on batteries requires specialist knowledge.The battery is virtually maintenance-free and is checked in the Inspection
Services.
We recommend that you replace a battery once it is older than 5 years.
Disconnecting the battery
If the battery is disconnected, some of the vehicle's functions will become
inoperative (e.g. electric windows). These functions will require resetting
after the battery is reconnected. For th is reason, the battery should only be
disconnected from the vehicle's electr ical system when absolutely necessary.
Long periods of non-use
The battery will gradually lose its charge because certain electrical equip-
ment continues to draw current even when the ignition is off. If you park the
vehicle for long periods of time in winter you should take the battery out of
the vehicle and keep it in a frost-proof room. Store the battery in a place
where it cannot “freeze up” and become damaged. At warm outside temper-
atures it is sufficient to disconnect the negative terminal of the battery. Even
when the battery is not connected you should charge it from time to time.

Wheels and tyres231
Safety First
Operating instructions
Practical tips
Te c h n i c a l D a t a
Wear indicators
The original tyres on your vehicle have 1.6 mm high “tread wear indicators”
⇒
page 230, fig. 173 , running across the tread. Depending on the make,
there will be six to eight of them evenly spaced around the tyre. Markings on
the tyre sidewall (for instance the letters “TWI” or other symbols) indicate the
positions of the tread wear indicators. The minimum tread depth required by
law is 1.6 mm (measured in the tread grooves next to the tread wear indica-
tors). Worn tyres must be replaced. Different figures may apply in export
countries ⇒.
Tyre pressure
Under-inflation or over-inflation will reduce the life of the tyres considerably
and also impair the car's handling. The inflation pressures are listed on a
sticker on the inside of the fuel tank flap.
Correct inflation pressures are very important, especially at high speeds. The
pressure should therefore be checked at least once a month and before
starting any long journey.
Tyre pressure monitoring (RKA+)*
Monitoring of the tyre pressures is based on the tyre pressures you have
stored. The tyre pressure monitoring syst em cannot function as intended if
you store tyre pressure settings for a normal load, but then drive with the
vehicle fully laden. The tyre pressure must be adapted to the actual load and
stored accordingly in the tyre pressure monitoring system ⇒page 229.
Driving style
Fast cornering, heavy acceleration and hard braking all increase tyre wear.
Changing wheels around
If the front tyres are worn considerably more than the rear ones it is advisable
to change them around as shown ⇒page 230, fig. 174 . All the tyres will then
last for about the same time. Wheel balance
The wheels on new vehicles are balanced. However, various factors encoun-
tered in normal driving can cause them to become unbalanced, which results
in steering vibration.
Unbalanced wheels should be rebalanced, as they otherwise cause excessive
wear on steering, suspension and tyres. A wheel must also be rebalanced
when a new tyre is fitted.
Incorrect wheel alignment
Incorrect wheel alignment causes excessive tyre wear, impairing the safety of
the vehicle. If tyres show excessive wear, you should have the wheel align-
ment checked by an Authorised Service Centre.
WARNING
There is a serious danger of accidents if a tyre bursts during driving!•
The tyres must be replaced at the latest when the tread is worn down to
the tread wear indicators. Failure to do so could result in an accident. Worn
tyres do not grip well at high speeds on wet roads. There is also a greater
risk of “aquaplaning”
•
At continuously high speeds, a tyre with insufficient pressure flexes
more. This causes it to overheat. This can cause tread separation and tyre
blow-out. Risk of accident. Always observe the recommended tyre pres-
sures.
•
If tyres show excessive wear, you should have the running gear checked
by an Authorised Service Centre.
•
Keep chemicals such as oil, fuel and brake fluid away from tyres.
•
Damaged wheels and tyres must be replaced immediately!For the sake of the environment
Under-inflated tyres will increase fuel consumption.
