The TCS should be switched on again afterwards as soon as possible.
WARNING
•
It must be remembered that TCS cann
ot defy the laws of physics. This
should be kept in mind, particular ly on slippery and wet roads and when
towing a trailer.
•
Always adapt your driving style to suit the condition of the roads and
the traffic situation. Do not let the extra safety afforded by TCS tempt you
into taking any risks when driving, this can cause accidents.Caution
•
In order to ensure that TCS function correctly, all four wheels must be
fitted with the same tyres. Any differences in the rolling radius of the tyres can
cause the system to reduce engine power when this is not desired.
•
Modifications to the vehicle (e.g. to the engine, the brake system, running
gear or any components affecting the wh eels and tyres) could affect the effi-
ciency of the ABS and TCS.
Electronic stabilisation program (ESP)*General notes
The electronic stabilisation program increases the vehicle's
stability on the road.The electronic stabilisation program helps to reduce the danger of skidding.
The electronic stabilisation programme (ESP) consists of ABS, EDL, TCS and
Steering manoeuvre recommendations. Electronic Stabilising Program (ESP)*
ESP reduces the danger of skidding by braking the wheels individually.
The system uses the steering wheel angle and road speed to calculate the
changes of direction desired by the driver, and constantly compares them
with the actual behaviour of the vehi
cle. If the desired course is not being
maintained (for instance, if the car is starting to skid), then the ESP compen-
sates automatically by braking the appropriate wheel.
The forces acting on the braked wheel bring the vehicle back to a stable
condition. If the vehicle tends to oversteer, the system will act on the front
wheel on the outside of the turn.
Steering manoeuvre recommendations
This is a complementary safety function included in the ESP This function aids
the driver to better stabilize the vehicle in a critical situation. For example, in
case of sudden braking surface with varied adherence, the vehicle will tend
to destabilize its trajectory to the right to or to the left. In this case the ESP
recognizes the situation and helps the driver with a counter steering
manoeuvre from the power steering.
This function simply provides the dr iver with a recommended manoeuvre in
critical situations.
The vehicle doesn't steer itself with this function, the driver has full control of
the vehicle at all times.
WARNING
•
It must be remembered that ESP cann ot defy the laws of physics. This
should be kept in mind, particularly on slippery and wet roads and when
towing a trailer.
•
Always adapt your driving style to suit the condition of the roads and
the traffic situation. Do not let the extra safety afforded by ESP tempt you
into taking any risks when driving, this can cause accidents.

Caution•
In order to ensure that ESP functions correctly, all four wheels must be
fitted with the same tyres. Any differences in the rolling radius of the tyres can
cause the system to reduce engine power when this is not desired.

Modifications to the vehicle (e.g. to the engine, the brake system, running
gear or any components affecting the wheels and tyres) could affect the effi-
ciency of the ABS, EDL, ESP and TCS.Note
To disconnect using the ESP button ⇒page 160.Anti-lock brake system (ABS)The anti-lock brake system prevents the wheels locking during braking
⇒page 180.Electronic differential lock (EDL)*
The electronic differential lock helps prevent the loss of trac-
tion caused if one of the driven wheels starts spinning.EDL helps the vehicle to start moving, accelerate and climb a gradient in slip-
pery conditions where this may otherwise be difficult or even impossible.
The system will control the revolutions of the drive wheels using the ABS
sensors (in case of an EDL fault the warning lamp for ABS lights up)
⇒page 78.
At speeds of up to approximately 80 km/h, it is able to balance out differ-
ences in the speed of the driven wheel s of approximately 100 rpm caused by a slippery road surface on
one side of the vehicle. It does this by braking the
wheel which has lost traction and distributing more driving force to the other
driven wheel via the differential.
To prevent the disc brake of the braked wheel from overheating, the EDL cuts
out automatically if subjected to excessive loads. The vehicle will continue to
function normally without EDL. For this reason, the driver is not informed that
the EDL has been switched off.
The EDL will switch on again automatically when the brake has cooled down.
WARNING
•
When accelerating on a slippery surface, for example on ice and snow,
press the accelerator carefully. Despite EDL, the driven wheels may start to
spin. This could impair the vehicle's stability.
•
Always adapt your driving style to su it road conditions and the traffic
situation. Do not let the extra safety afforded by EDL tempt you into taking
any risks when driving, this can cause accidents.Caution
Modifications to the vehicle (e. g. to the engine, the brake system, running
gear or any components affecting the wh eels and tyres) could affect the oper-
ation of the EDL ⇒page 201.The traction control system (TCS)The traction control system prevents the drive wheels from spinning when the

Driving and the environmentRunning-inRunning-in a new engine
The engine needs to be run-in over the first 1,500 km.Up to 1,000 kilometres
– Do not drive faster than three quarters of top speed.
– Do not accelerate hard.
– Avoid high engine revolutions.
– Do not tow a trailer.
From 1000 to 1500 km
–Speeds can be gradually increased to the maximum road speed
or maximum permissible engine speed (rpm).During its first few hours of running, the internal fric tion in the engine is
greater than later on when all the moving parts have bedded in.
For the sake of the environment
If the engine is run-in gently, the life of the engine will be increased and its oil
consumption reduced.
Running-in tyres and brake pads
New tyres should be run-in carefully for the first 500 km. New
brake pads should be run-in carefully for the first 200 km.During the first 200 km, you can compensate for the reduced braking effect
by applying more pressure to the brake pedal. If you need to make an emer-
gency stop, the braking distance will be longer with new brake pads than with
brake pads that have been run-in.
WARNING
•
New tyres do not give maximum grip to start with, and require running-
in. This may cause an accident. Drive particularly carefully in the first 500
km.
•
New brake pads must be “run-in” and do not have the correct friction
properties during the first 200 km. However, the reduced braking capacity
may be compensated by pressing on the brake pedal a little harder.
Braking effect and braking distance
The braking effect and braking distance are influenced by
driving situations and road conditions.The efficiency of the brakes depends directly on the brake pad wear. The rate
of wear of the brake pads depends to a great extent on the conditions under
which the vehicle is operated and the way the vehicle is driven. If you often
drive in town traffic, drive short distances or have a sporty driving style, we
recommend that you have the thickness of your brake pads checked by an

Driving and the environment
184Authorised Service Centre more frequently than recommended in the Service
Schedule.
If you drive with wet brakes, for example after driving through water, after
heavy rainfall or after washing the car, the braking effect will be reduced as
the brake discs will be wet, or possibly frozen (in winter): the brakes must be
“dried” through careful braking.
The brake fluid must be changed every two years at the latest. Heavy use of
the brakes may cause a vapour lock if the brake fluid is left in the system for
too long. This prevents the brakes developing their full braking effect.
WARNING
Longer braking distances and faults in the brake system increase the risk
of accidents.•
New brake pads must be run-in and do not have the correct friction
during the first 200 km. However, the reduced braking capacity may be
compensated by pressing on the brake pedal a little harder. This also
applies when new brake pads are fitted.
•
If brakes are wet or frozen, or if you are driving on roads which have
been gritted with salt, braking power may set in later than normal.
•
On steep descents if the brakes are excessively used they will over
heat. Before driving down a long steep gradient, it is advisable to reduce
speed and change to a lower gear (or mo ve the selector lever to a lower gear
if your vehicle has automatic transmission). This makes use of engine
braking and relieves the brakes.
•
Never let the brakes “rub” by applying light pressure. Continuous
braking will cause the brakes to overheat and will increase the braking
distance. Apply and then release the brakes alternately.
•
Never let the vehicle coast with the engine switched off. The braking
distance is increased considerably as the brake servo does not function.
•
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 201, “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 run the fuel tank dry.
– For engine oil changes, do not replenish with too much engine oil ⇒page 214, “Topping up engine oil ”.
– Never tow the vehicle to start it, use jump leads if necessary ⇒page 258.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 72. 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 towing bracket ball coupling must be stored securely in the luggage
compartment to prevent them being flung through the vehicle and causing
injury.
Note
•
By law, the ball coupling must be removed if a trailer is not being towed
and it obscures the number plate.
Driving tips
Driving with a trailer always requires extra care.Weight distribution
The weight distribution of a loaded trailer with an unladen vehicle is very
unfavourable. However, if this cannot be avoided, drive extra slowly to allow
for the unbalanced weight distribution.
Speed
The stability of the vehicle and trailer is reduced with increasing speed. For
this reason it is advisable not to drive at the maximum permissible speed in
unfavourable road, weather or wind conditions. This applies especially when
driving downhill.
You should always reduce speed immediately if the trailer shows the slightest
sign of snaking . Never try to stop the “snaking” by increasing speed.
Always brake in good time. If the trailer has an overrun brake, apply the
brakes gently at first and then firmly. This will pr event the jerking that can be
caused by the trailer wheels locking. Select a low gear in good time before
going down a steep descent. This enables you to use the engine braking to
slow down the vehicle. Heating
At very high temperatures and during prolonged ascents, driving in a low gear
and high engine speed, always moni
tor the temperature indicator for the
coolant ⇒page 55.
Electronic Stabilisation Program*
Do not switch off the ESP* when towing a trailer. The ESP* makes it easier to
stabilise if the trailer starts to snake.
Driving economically and with respect for the
environmentGeneral notes
Fuel consumption depends largely on your personal driving
style.Fuel economy, environmental impact and wear on the engine, brakes and
tyres depend largely on three factors:•
Personal driving style
•
Conditions of use (weather, road surface)
•
Technical requirements
By adopting an economical driving style and anticipating the traffic situation
ahead, you can easily reduce fuel consumption by 10-15%. This section
suggests methods of lessening the impact on the environment and reducing
your operating costs at the same time.

Think ahead when drivingA vehicle uses most fuel when accelera ting. If you think ahead when driving,
you will need to brake less and thus accelerate less. Wherever possible, let
the vehicle roll slowly to a stop, for instance when you can see that the next
traffic lights are red.Regular servicingBy taking your car to an Authorised Service Centre for regular servicing you
can establish a basis for good fuel economy before you start driving. A well-
serviced engine gives you the benefit of improved fuel efficiency as well as
maximum reliability and an enhanced resale value.
A badly serviced engine can consume up to 10% more fuel than necessary.
Check the oil level every time you fill the tank ⇒page 213. Oil consumption
depends to a great extent on the engine load and engine speed. Depending
on your personal driving style, oil consumption can be up to 1 litre per 1,000
km.
Avoid short journeysThe engine and catalytic converter need to reach their proper working
temperature in order to minimise fuel consumption and emissions.
Directly after a cold start, the engine uses about 50-70 litres of fuel per
100 km. This figure then drops to 20 -30 litres per 100 km after about one
kilometre. The engine only reaches its working temperature after about four
kilometres, when fuel consumption will return to a normal level. You should
therefore avoid short journeys.
The ambient temperature has a decisive influence.
The illustration shows the different rates of fuel consumption for the same
distance at both +20°C and -10°C. Your vehicle will use more fuel in winter
than in summer.

tion in litres per 100 km at

Cleaning and caring for your vehicle
192Cleaning and caring for your vehicleGeneral notesRegular washing and care help maintain the value of your
vehicle.Regular care
Regular and expert care helps to maintain the value of the vehicle. This may
also be one of the requirements for acknowledging warranty claims in the
event of corrosion or paint defects.
The best way to protect the car against environmental contaminants is to
wash and wax it frequently. The longer substances such as insects, bird drop-
pings, resinous tree sap, road dirt, industrial deposits, tar, soot or road salt
and other aggressive materi als 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 the period when salt is put on the roads it is important to have the
underside of the vehicle washed thoroughly.
Car care products
Car care products are available from your Authorised Service Centre. Keep the
product instructions until you have used up the product.
WARNING
•
Car care products can be toxic. For this, they must always be kept
closed in their original container. Keep out of children's reach. 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;
these 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. There is a fire / explo-
sion risk.
•
Before you wash your vehicle, or ca rry out any maintenance, switch off
the engine, apply the handbrake firmly and remove the key from the igni-
tion.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 glass on your vehicle. Soak dirt, mud or dust with plenty of
water.
For the sake of the environment
•
When purchasing car care products, try to select ones which are not
harmful to the environment.
•
Left over car care products should not be disposed of with ordinary house-
hold waste. Observe the disposal information on the package.WARNING (continued)

Care of the vehicle exteriorAutomatic car washesThe paint is so durable that the car can normally be washed without problems
in an automatic car wash. However, the effect on the paint depends to a large
extent on the design of the car wash, the brushes used, the filtering of the
wash water and the type of detergents and wax solutions used, etc.
After the car has been washed, the brakes could respond later than normal as
the brake discs and brake pads will be wet, or even frozen in winter. You must
“dry” the brakes by applying the brakes carefully several times ⇒page 183,
“Braking effect and braking distance”.
WARNING
Moisture, ice and salt on the brakes may affect braking efficiency. Risk of
accident.Washing by handWashing the vehicle
– First soften the dirt with plenty of water and rinse off.
– Clean the vehicle with a soft sponge, a glove or a brush. Start on the roof and work your way down. Use only light pressure.
– Rinse the sponge or glove as much as possible.
– Special car shampoo should only be used for very stubborn dirt. – Clean the wheels, sill panels etc. last using a different sponge or
glove.
– Rinse the vehicle thoroughly with water.
– Dry the surface of the vehicle gently using a chamois leather.
–If it is cold, dry the rubber seals and th e surfaces they touch with
a cloth to prevent them freezing. Apply silicone spray to the
rubber seals.
After cleaning the vehicle
– If possible, avoid sudden braking directly after washing the vehicle. You must “dry” the brakes by applying the brakes care-
fully several times ⇒page 183, “Braking effect and braking
distance”.
WARNING
•
The ignition must always be switched off before the vehicle is washed.
•
Protect your hands and arms from cuts on sharp metal edges when
cleaning the underbody, the inside of the wheel housings etc. Risk of
injury.
•
Moisture, ice and salt on the brakes may affect braking efficiency. Risk
of accident.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 cleaning purposes. This could scratch
the paintwork or glass on your vehicle.
•
Washing the vehicle in cold weather: if the vehicle is rinsed with a hose,
do not direct the water into the lock cylinders or the gaps around the doors,
