CAUTION
- Have your qualified workshop check the
cooling system before the winter season to
make sure that the anti-freeze concentra
tion is adequate for the conditions to be ex
pected. This applies particularly if you drive
into a colder climate zone.
- To prevent damage to the engine, do not
use a different type of anti-freeze additive if
the approved type of additive is not availa
ble. In this case use only water and bring
the coolant concentration back up to the
correct level as soon as possible by putting
in the specified additive.
- Always top up with fresh, unused coolant.
- Radiator sealants must not be added to the
coolant.

Checking coolant level
.. Park your vehicle on a level surface .
.. Switch off the ignition .
.. Read off the coolant level on the coolant expan
sion tank

.. You should make sure that the fluid level re-
mains stable. If necessary, add more coolant.
.. Screw the cap on again tightly.
Any loss of coolant normally indicates a leak in
the cooling system. Drive to a qualified workshop
without delay and have the cooling system
checked. If there are no leaks in the system, a
loss of coolant can only occur if the coolant boils
and is forced out of the system as a result of
overheating.
A
WARNING
- The cooling system is under pressure. Do
not unscrew the cap on the expansion tank
when the engine is hot: you could be scal
ded by escaping steam.
- The coolant and coolant additive can be a
health hazard. Store the coolant additive in
the original container in a safe place out of
reach of children - risk of poisoning.
- When working in the engine compartment
be aware that the radiator fan may start
running suddenly, even if the ignition is
switched off- risk of injury!

CAUTION
Do not add coolant if the expansion tank is
empty. Air could have got into the cooling sys
tem - risk of engine damage! In this case, do
NOT drive on. Obtain professional assistance .
