Liquid coolant losses
Any loss of liquid coolant normally indicates a
leak in the cooling system. In
this case the cooling system should be inspected by a specialist garage
without delay. It is not sufficient merely to top up the liquid coolant.
If there are no leaks in the system, a loss of liquid coolant can only occur if
the coolant boils and is forced out of the system as a result of overheating.
Caution
Radiator sealants must not be added to the liquid coolant. Such additives
could seriously impair the function of the cooling system.Topping up the liquid coolant
Be careful when topping up with liquid coolant.– Switch the engine off.
– Wait for the engine to cool down.
– Cover the cap on the expansion tank ⇒page 226, fig. 172 with a
cloth, and carefully unscrew the cap anti-clockwise ⇒.
– Add liquid coolant.
– Screw on the cap tightly.Make sure that the liquid coolant meets the required specifications
⇒page 225, “Liquid coolant”. Do not use a different type of anti-freeze if
anti-freeze G12++ is not available. In this case, use only water and bring the
anti-freeze concentration back up to the correct level as soon as possible.
Always top up with new liquid coolant. Do not fill above the “max” mark. Excess liquid coolant is forced out of the
system through the valve in the filler cap when the engine gets hot.
If a lot of liquid coolant has been lost, wait for the engine to
cool down before
putting in cold coolant. Failure to do so could result in serious engine
damage.
WARNING
•The cooling system is under pressure. Do not unscrew the cap on the
expansion tank when the engine is hot. Failure to comply could result in
burns.•The anti-freeze and liquid coolant can be a health hazard. Therefore,
the anti-freeze should be stored in the original container in a safe place out
of reach of children. Failure to comply could result in poisoning.For the sake of the environment
Drained off coolant should not be used again. Drain off the used coolant into
a suitable container and dispose of it in the proper manner (observe environ-
mental regulations).Radiator fan
The radiator fan can start running spontaneously.The auxiliary fan can continue to run for as long as 10 minutes after stopping
the engine – even after the ignition is switched off. It may also start running
suddenly ⇒ after some while if•stored heat raises the coolant temperature, or•the hot engine compartment is additionally heated up by the sun.

Wheels and tyres
240Anti-puncture tyres*
Anti-puncture tyres allow you to continue driving even with a
punctured tyre, in the majority of cases.Vehicles equipped with anti-puncture
4) tyres from the factory indi-
cate the loss of tyre pressure on the instrument panel.
Driving with anti-puncture tyres (emergency gear)
– Leave the ESP/TCS (electronic stabilisation programme) switched on, or switch on ⇒page 68.
– Continue driving carefully and slowly (80 km/h maximum).
– Avoid sudden manoeuvres and sharp turns.
– Avoid driving over obstacles (for example kerbs) or potholes.
– Look out for the ESP/TCS intervening often, smoke coming from the tyres or the smell of rubber, the vehicle vibrating or a clat-
tering noise. If any of these occur, stop the vehicle.
The anti-puncture tyres have a tag on the side of the tyre, with the description:
“DSST”, “Eufonia”, “RFT”, “ROF”, “RSC”, “SSR” or “ZP”.
The sides of this type of tyre are reinforced. When the tyres lose air they are
supported on the sides (emergency driving).
The loss of pressure in the tyre is shown on the instrument panel. You can
then drive a maximum of 80 km and if the circumstances are favourable (for
example, low load), even more.
The damaged tyre should be changed as soon as possible. The rim should be
checked in a specialist workshop to detect possible damage and replace it if necessary. We recommend you contact Technical Service. If more than one
tyre is being used under emergency co
nditions, this reduces the distance
which can be travelled.
Starting driving in emergency conditions
When loss in tyre pressure is displayed on the instrument panel, this means
that at least one tyre is being driven in emergency conditions ⇒.
End of emergency operation
Do not drive on if:
•smoke is coming from one of the tyres,•there is a smell of rubber,•the vehicle vibrates,•there is a rattling noise.
When is it no longer possible to continue driving even using anti-puncture
tyres?•If the Electronic Stabilisation Program (ESP) is out of operation.•If the tyre pressure monitoring system is out of operation.•If one of the tyres has been severely damaged in an accident, etc. If a tyre
has been badly damaged there is a risk that parts of the tread can be thrown
off and cause damage to the fuel lines, brake pipes or fuel filler.•It is also advisable to stop driving if severe vibrations occur, or if the wheel
starts overheating and gives off smoke.WARNING
When driving in emergency conditions, the driving quality of the vehicle is
considerably impaired.•The maximum permitted speed of 80 km/h is subject to road and
weather conditions. Please observe legal requirements when doing so.•Avoid sharp turns and rapid manoeuvres, and brake earlier than usual.
