Coolant
 Introduction
This chapter contains information on the following subjects:
Checking and refilling
257
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 252.■
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 - There is a risk of the engine overheating.256General Maintenance

fied water, and get a specialist garage to correct the water-coolant additive
mix as soon as possible.
CAUTION■ If the expansion tank is empty, do not top up with coolant. The system could
aerate - There is a risk of engine damage!  Stop driving! Switch off the en-
gine and seek assistance from a specialist garage.■
Do not fill the coolant above the mark
A
» Fig. 294 . The coolant could, when
heated, be expelled from the cooling system - There is a risk of damage to the
engine parts.
■
If it is not possible to add coolant, 
stop 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 distilled (purified) water has been used to top up, the coolant should be re-
placed 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
A coolant level which is too low is indicated in the instrument cluster by the
warning light and shown by the relevant message » page 38. We still recom-
mend inspecting the coolant level directly at the reservoir from time to time.

The vehicle battery represents a power source for the motor to start and for the supply of electrical consumers in the car.
Automatic consumer shutdown - Discharge protection of the vehicle battery
The on-board power supply system tries to prevent the vehicle battery from
discharging in the following ways when it is subject to heavy loading. ▶ By increasing the engine idle speed.
▶ Through the power limitation of certain loads.
▶ By switching off some loads(heated seats, heated rear window) for as long
as necessary.
Warning symbols on the vehicle batterySymbolMeaningAlways wear eye protection!Battery acid is severely caustic. Always wear gloves and eye pro-
tection!Keep fire, sparks, open flames and lit cigarettes well clear of the
vehicle battery!When charging the vehicle battery, a highly explosive gas mixture
is produced!Keep children away from the vehicle battery!WARNINGBattery acid is highly corrosive - it can cause injury, chemical burns or poi-
soning! Corrosive vapours in the air irritate and damage the respiratory
tract and the eyes. The following guidelines must be observed.■
Always wear protective gloves, eye and skin protection when handling
the vehicle battery.
