Warning lamps
Attention • Be careful when opening the coolant expansion tank! When the engine is hot the cooling sys­tem is under pressure -Danger of scalding! Let engine cool down therefore before unscrewing the cap_
• Do not touch the fan. The fan can switch on suddenly -even when ignition is switched off.
For furthe r details see pages 98 and 98.

Attention
Particular care should be taken
when working in the engine com­
partment!

• Switch off engine. remove ignition key_
•
Pull handbrake on firmly.
• Move gear lever into neutral or
"P" position.

• Allow engine to cool off.
• As long as the engine is at op­
erating temperature:
-Do not put your hand into the
radiator fan. it could switch on
suddenly.
-Do not open the radiator cap be­
cause the cooling system is
under pressure.
• Avoid causing short circuits in
the electrical system -particu­
larly at the battery -.

• If tests have to be ca rried o ut with the engine running. there is an additional dang e r present from rotating parts - e.g . ribbedl V-belts, alternator, ra d iator fan etc. -and fro m the high voltage ignition system.
Attention m ust be paid to the w arn ings given in this Instruc­tion Manual and to the generally ap plicable safety regulations.
When topp ing up fluids one should ensure that they are not mistaken. one for the other, under any circum ­stances. otherwise serious fu nc­tional defects will result.
rJjh So that leaks are quickly de­(!J!J tected the ground underneath the vehicle should be checked reg­ularly. If spots as caused by oil or other operating fluids can be seen, the vehicle should be taken to the workshop for checking.

Coolant losses
Coolant loss normally indicates leaks in the
system . In this case the cooling system
should be checked by a Volkswagen dealer
w it h out delay . It is not sufficient merely to
add coolant.
Ii'! ~ ~MI~d ~v~t~m IMMS canonly occur if the boiling point of the coolant is exceeded as a result of overheating, and coolant is forced out of the system.
Topping up coolant
Switch engine off and let it cool down . Then
cover expansion tank cap with a cloth and
turn cap carefully
to the left
and remove.
Attention Do not remove expansion tank cap when engine is hot -Danger of scalding. System is under pressure.
If, in an emergency only water can be added the correct mixture concentration
must be restored with the specified coolant
additive (see previous page) as soon as possible. If
a lot of coolant has been lost.
on l y add cold
coolant after the engine has cooled down.
This will prevent engine damage.
Do not fill above the MAX. mark.
The excess coolant will be forced out
through the pressure rel ief valve in the cap
when engine becomes hot.
Screw cap on again tightly.
Attention The coolant additive and the coolant are a danger to health. The additive must therefore only be stored in the original con­tainer well out of reach of children. If the coolant has to be drained at any time it must be caught and also stored in a safe place.
dih Drained coolant should not nor­~mally be reused, it must be dis­posed of, bearing in mind environ­mental protection regulations.
Fan
The radiator fan is driven electrically and controlled by a thermoswitch from the cool­
ant temperature (also from the engine com­
partment temperature
on some models).
Attention After the engine has been stopped the fan can continue running for a while -even with the engine switched off -(up to about 10 minutes). It can also start to run again suddenly after a short time if -the coolant temperature in­creases due to heat build-up
when engine is hot and the en­gine compartment is heated additionally by strong sun­light.
Special care must therefore be taken when working in the en­gine compartment.
