Tyre pressure monitoring
Introduction
This chapter contains information on the following subjects:
Storing the tyre pressure values.
109
108Driving

The tyre pressure monitoring function (hereinafter referred to as: the system)
monitors the tyre pressure while driving.
If the tyre inflation pressure changes, the warning light
lights up in the in-
strument cluster and an audible signal is heard » page 34,
.
The system can only function properly if the tyres have the prescribed inflation pressure and these pressure values are stored in the system.WARNING■ The general information relating to the use of assistance systems must
be observed » page 103, in section Introduction .■
Having the correct tyre inflation pressure is always the driver's responsi-
bility. Tyre pressure should be checked regularly » page 129.
■
The system cannot warn in case of very rapid tyre inflation pressure loss,
e.g. in case of sudden tyre damage.
Storing the tyre pressure values.

The jack is maintenance-free. If necessary, the moving parts of the jack should
be lubricated with a suitable lubricant.
Protection of cavities
All the cavities of your vehicle which are at risk from corrosion are protected by
a layer of long-lasting protective wax applied in the factory.
If any small amount of wax flow out of the cavities at high temperatures, these
must be removed with a plastic scraper and the stains cleaned using a petrole-
um cleaner.
Underbody
The underside of your vehicle is already permanently protected by the factory
against chemical and mechanical influences.
We recommend having the protective coating — preferably before the begin-
ning of winter and at the end of winter.
Product life of the films
Environmental influences (eg. sunlight, humidity, air pollution, chipping) will af-
fect the life of the films. Films will age and become brittle - this is entirely nor-
mal; this is not a fault.
The sunlight may also affect the strength of the film colour.
When transporting a load on the roof rack (e.g. roof box or similar) there is an
increased risk of film damage (e.g. of chipping from the secured load).
CAUTION
■ Vehicle paint
■ Repair damaged areas as soon as possible.
■ Matt-painted parts should not be treated with polishes or hard waxes.
■ Do not polish in a dusty environment - risk of paint scratches.
■ Do not apply any paint care products to door seals or window guides.■
Plastic parts
■ Do not use paint polish.
■
Chromed and anodised parts
■ Do not polish in a dusty environment - risk of surface scratches.
■
Films
The following instructions must be observed, otherwise there is a risk of film
damage. ■ Do not use dirty cloths or sponges for cleaning.
■ Do not use a scraper or other means to remove ice and snow.
■ Do not polish the films
■ Do not use a high pressure cleaner on the films.
■
Rubber seals
■ Do not treat the door seals and window guides deal with anything - the
protective varnish coating could be damaged.
115Care and maintenance

■Windows and door mirrors
■ Do not clean the insides of the windows/mirrors with sharp objects - risk of
damage to the filaments or the antenna. ■ Do not use a cloth which has been used to polish the body - this could dirty
the window and impair visibility.■
Head / tail lights
■ Do not wipe head/tail lamps dry, do not use any sharp objects - risk of dam-
age to the protective coating and cracks forming on the headlamp glass cov-
ers.
■
Door lock cylinders ■ Make sure that as little water as possible gets into the locking cylinder
when washing the vehicle - there is a risk of freezing the lock cylinder!
■
Wheels
■ Heavy soiling of the wheels can affect the balance of the wheels - the re-
sult can be a vibration, which can cause premature wear of the steering.

Coolant
Introduction
This chapter contains information on the following subjects:
Checking and refilling
125
The coolant helps to keep the engine temperature down, and consists of wa-
ter and coolant additive (with additives that protect the cooling system against
corrosion and prevent furring).
The proportion of coolant additive in the coolant must be 40 to 60 %.
The correct mix of water and coolant additive should be checked and if neces-
sary corrected by a specialist garage.
WARNING■ The following instructions must be followed at all times when working on
the engine compartment » page 120.■
Never open the end cover of the coolant expansion reservoir while the
engine is still warm. The cooling system is pressurised - risk of scalding or
injury from splashes of coolant!
■
To protect against the coolant splashing, cover the cap with a cloth when
opening.
■
Coolant and coolant fumes are harmful - avoid contact with the coolant. If
the coolant comes into contact with the eye or skin, wash the affected area
with plenty of water for several minutes, and where appropriate seek medi-
cal help.
CAUTION
Do not cover the radiator and install any parts (e.g auxiliary lights.) in front of
the air intakes - risk of the engine overheating.124General Maintenance

Checking and refillingFig. 140
Coolant expansion reservoir
Read and observe and on page 124 first.
Check and refill coolant under the following conditions.The vehicle is on a horizontal surface.
The engine is not warm (if the engine is warm the result of the check may
be wrong).
The engine is turned off.
Check the coolant level - The coolant level must lie between the marks
A
and
B
» Fig. 140. If the coolant level is below the mark
B
, top up with coolant.
Refilling
The reservoir must always contain a small amount of coolant »
.
›
Place a cloth over the cap of the coolant expansion tank and unscrew the
cap carefully .
›
Always top up using coolant of the correct specification.
›
Turn the cap until it clicks into place.
The specification for the coolant is shown in the coolant expansion reservoir
» Fig. 140 .
If the specified coolant is not available, then refilling only with distilled or dem-
ineralised water, and get a specialist garage to correct the water-coolant addi-
tive mix as soon as possible.
CAUTION■ If the expansion tank is empty, do not top up with coolant. The system could
aerate - risk of engine damage! Stop driving! Switch off the engine and seek
assistance from a specialist garage.■
Do not fill the coolant above the mark
A
» Fig. 140 . The coolant could, when
heated, be expelled from the cooling system - risk of damage to the engine
parts.
■
If it is not possible to add coolant,
do not continue driving! Switch off the
engine and seek assistance from a specialist garage.
■
A coolant additive which does not correspond to the correct specification can
reduce the anti-corrosion effect of the cooling system - risk of damage to the
cooling system and the engine.
■
If non-distilled (non-demineralised) water has been used to top up, the cool-
ant should be replaced by a specialist garage - risk of engine damage.
■
A loss of coolant indicates leaks in the cooling system - risk of engine dam-
age. Top up with coolant and then seek assistance from a specialist garage.
Note
If the coolant level is too low, a warning light lights up in the instrument clus-
ter » page 33 . We still recommend inspecting the coolant level directly at the
reservoir from time to time.
Brake fluid
