The ESP increases the control over the vehicle in situations such as
accelerating or in turns.
The ESP expands the functions of the ABS/TCS and decreases
under any circumstance the risk of skidding. This contributes to an
improved stability of the vehicle.The system works in the realm of speed in relation to the ABS. In
case of a failure of the ABS, the ESP will also fail.
The ESP connects automatically when the engine is switched on
and checks itself.
If needed, the system can be switched on or off by pressing the
button.
When the system is off, the ESP warning light will light up
⇒
"Warning lights" chapter.
The ESP should always be connected. Only in exceptional cases,
when the skidding effect is desired under extremely sporty
conditions, the system can be disconnected.
Afterwards the system should be reconnected.
The ABS and EDS
⇒"Switches" chapter remain connected even
when the ESP is off.

The electronic stability program encompasses the ABS, EDS and
TCS. In addition to all available data for these functions, the ESP
control unit needs additional measurements supplied by high
precision sensors. The measuring data consists of the speed at
which the vehicle turns around its vertical axis, acceleration,
pressure on brakes and the turn of the steering wheel.
With the help of the steering wheel sensor and the vehicle’s
speed, the desired direction is determined and constantly
compared to the vehicle’s real behavior. When differences occur,
such as incipient skidding, the ESP automatically brakes the
adequate wheel.

• As driving stability of vehicle and trailer decreaseswhen the
speed increases do not drive at the maximum permissible top
speed in unfavourable road, weather or wind conditions –
particularly when going downhill.
In any case the speed must be reduced as soon as the trailer
shows the slightest sign of snaking. On no account try to stop the
snaking by accelerating.

• Always brake in good time. If the trailer has an overrun brake,
apply the brakes gently at first then firmly. This will avoid the
jerking caused by the trailer wheels locking.
Change down before going down a steep hill so thatthe engine
can act as a brake.
• When a long climb in a low gear with extremely high engine revs
must be negotiated at exceptionally high ambient temperatures
the coolant temperature gauge must be observed. When the gauge
needle moves to the right end of the scale, the road speed must be
reduced immediately.
• The cooling effect of the radiator fan cannot be increased by
changing down, because the speed of the fan is not dependent on
the engine speed. One should therefore not change down even
when towing a trailer as long as the engine can cope without the
vehicle speed dropping too much.

shampoo, preferably with a neutral pH, should only be used for

•The vehicle should not be washed in strong sunshine.
•If the vehicle is rinsed with a hose, do not direct the jet of water
at the lock cylinders and the door/boot lid/tailgate shut lines –
they can freeze up in the winter.
K
Washing vehicle with high pressure cleaner
• The operating instructions for the high pressure cleaner must be
followed closely – particularly with regard to pressure and working
distance.
• Do not use a concentrated jet.
• The water temperature must not be above 60°C.
Conservation
Regular application of protection products protects the vehicle
paintwork to a large extent against the environmental influences
listed under “Washing” on the previous page and even against
light mechanical damage.
At the latest when water on the clean paint does not form small
drops and roll off, the vehicle should be protected by applying a
coat of good hard wax. Even when a wax solution is used regularly

181 Care and maintenance
Safety FirstControls and equipment Tips and Maintenance Technical Data
Steel wheels
The wheels and the wheel trims should be cleaned thoroughly at
regular intervals when the vehicle is being washed. This will
prevent brake dust, dirt and road salt from accumulating on the
wheel. Persistent ingrained brake dust can be removed with an
industrial grime remover. Paint damage should be repaired before
rust can form.
K
Alloy wheels*
In order to maintain the smart appearance of alloy wheels for a
long period, regular care is necessary. In particular, salt and brake
pad dust must be washed off thoroughly at least every two weeks
otherwise the surface of the alloy will be damaged. After being
washed, the wheels should be treated with an acid-free cleaner for
alloy wheels. About every three months it is necessary to give
wheels a good rubbing with hard wax. Paint polish or other
abrasive solutions must not be used. If the protective paint coat
has been damaged, e.g. by stone impact, the damaged spots
should be dealt with as soon as possible.
Cleaning and anti-corrosion treatment of engine
compartment
The leaves, blossoms etc. which drop into the water box
(underneath the engine bonnet in front of the windscreen) should
be cleaned out occasionally. This will prevent the water drain holes
from becoming blocked and – on vehicles without a dust and
pollen filter – foreign bodies entering the vehicle interior via the
heating and ventilation system.
The engine compartment and the outside surface of the power unit
are given anti-corrosion treatment at the factory.
In the winter when the vehicle is being driven frequently on salted
roads, good anti-corrosion treatment is very important. For this
reason the entire engine compartment and the plenum chamber
should be thoroughly cleaned before and after the salting period
and then preserved so that the salt cannot have a damaging effect.

• Keep grease, oil and fuel off the tyres.
• Replace missing dust caps as soon as possible.
• Mark wheels before taking them off so that they rotate in the

The inflation pressure is very important particularly at high speeds.
Therefore, the pressures should be checked at least once a
month and before every long journey.
At this opportunity do not forget the spare wheel:
• The spare wheel with normal tyre should always be inflated to
the highest pressure required on the vehicle.
• Always check the pressures when the tyres are cold. When warm,
the pressure is higher but do not reduce. If the load changes a
great deal the pressure must be altered to suit.
On vehicles with wheel hub caps, valve extensions are fitted. It is
not necessary to remove the valve extension piece in order to test
and correct the inflation pressure.

The wheels on new vehicles are balanced. However when the
vehicle is running various influences can cause the wheels to
become unbalanced and this causes steering vibration.
As imbalance also increases steering, suspension and tyre wear
the wheels should be balanced again. Furthermore a wheel should
always be rebalanced when the tyre has been repaired or when a
new tyre has been fitted.

When tread depth is down to 1.6 mm measured in the tread groove next to
the wear indicator bar – the official permissible minimum tread depth has
been reached (in export countries this figure may differ).

Renewing wheels/tyres
Wheels and tyres are important design features. The wheels and
tyres approved by us should be used. They are specially matched
to the model concerned and contribute largely to the excellent
roadholding and safe driving characteristics.

Because of the problems in disposing of old tyres and the specialised tools
and knowledge required, tyres should preferably be changed at a Technical
Service Centre.
• For safety reasons the tyres should be renewed in pairs and not
singly. The tyres with the deepest tread should always be on the
front wheels.
• You should only combine radial tyres of the same construction,
size (rolling circumference) and, as far as possible, the same tread
profile on all four wheels.
• On four wheel drive vehicles all tyres must be of the same brand.
Otherwise, the viscosity would unnecessarily increase the
proportion of the rear drive since the axes would be turning at
different speeds and this could cause damage.
•If the spare wheel has got a different use than the wheels the car
is using actually (for example, winter tyres or wide tyres), in case of
a breakdown it will only be possible to be used for a short time and
driving with special care. It will have to be replaced by the normal
wheel as soon as possible.
• Never fit used tyres whose previous history is not known.
• Knowing the tyre lettering and its meaning makes the selection
of the correct tyres easier. Radial ply tyres have the following
lettering on the sidewall:
