Opening the bonnet
The bonnet is released from inside the vehicle.

well area on driver side:

for bonnet.
Before opening the bonnet ensure that the windscreen wipers are
in rest position. –
To release the bonnet, pull the lever under the dash panel
⇒ fig. 161 in the direction indicated (arrow). The bonnet will be
released by a spring action ⇒
.
– Lift the bonnet using the release lever (arrow) and open the
bonnet.
– Release the bonnet stay and secure it in fixture designed for
this in the bonnet.
WARNING
Hot coolant can scald!
● Never open the bonnet if you see steam, smoke or coolant escaping
from the engine compartment.
● Wait until no more steam, smoke or coolant is emitted from the bon-
net, then carefully open the bonnet.
● When working in the engine compartment, always observe the safety
warnings ⇒ page 230.
Closing the bonnet
– Raise the bonnet slightly
– Release the bonnet stay and replace it in its support.
– At a height of about 30 cm let it fall so it is locked.
If the bonnet does not close, do not press downwards. Open it once more
and let it fall as before.

Checking and refilling levels
Coolant
Coolant specifications
Coolant is a mixture of water and at least 40% coolant addi-
tive. The cooling system must be filled with a mixture of water and at least 40 %
of our coolant additive G12+ or an additive with the specification TT-VW 774
F (it is dyed purple). This mixture provides the necessary freeze protection
down to -25 °C and protects the alloy parts of the cooling system against
corrosion. It also prevents scaling and raises the boiling point of the cool-
ant.
The concentration of coolant must always be at least 40% - even if freeze
protection is not required.
If greater freeze protection is required in very cold climates, the proportion
of the antifreeze additive G12+ can be increased. However, the percentage
of coolant additives should not exceed 60%, as this would reduce the
freeze protection. It would also reduce the cooling effect. A mixture with
60% additive will give antifreeze protection to approx. -40 °C.
WARNING
● The coolant additive is toxic. There is a toxic risk. Always keep the
coolant additive in the original container which should be stored out of
the reach of children. The same applies to coolant which you have
drained off.
● The coolant additive G12+ must be added in sufficient quantities to
provide anti-freeze protection at the coldest ambient temperatures that
can be expected. At extremely cold outside temperatures, the coolant
could freeze, causing the vehicle to breakdown. As the heater would not
work either, there is a risk of freezing to death.
CAUTION
● Other additives may give considerably inferior corrosion protection. The
resulting corrosion in the cooling system can lead to a loss of coolant, caus-
ing serious damage to the engine.
● The coolant additive G12+ (purple) can be mixed with the additive G12
(red) or G11. Never mix G12 (red colour) with G11.
Checking the coolant level and topping up
The correct coolant level is important for fault-free function-
ing of the engine cooling system.

238Checking and refilling levels
Opening the coolant expansion tank
–Switch off the engine and allow it to cool.
– To prevent scalding, cover the cap on the expansion tank with a
thick cloth and carefully unscrew the cap ⇒
.
Checking coolant level
– Look into the open coolant expansion tank and read off the
coolant level.
– If the level is below the “MIN” mark, top up with coolant.
Topping up coolant
– Only use new coolant liquid.
– Do not fill above the “MAX” mark.
Closing the coolant expansion tank
– Screw the cap on again tightly.
The position of the coolant expansion reservoir is shown in the correspond-
ing engine compartment illustration ⇒ page 287.
Make sure that the coolant meets the required specifications ⇒ page 237.
Do not use a different type of additive if additive G12+ is not available. 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
⇒ page 237.
Always top up with new coolant.
Do not fill above the “MAX” mark. Otherwise the excess coolant will be
forced out of the cooling system when the engine is hot.
The coolant additive G12+ (dyed purple) may be mixed with G12 (dyed red)
and also with G 11.
WARNING
Any work carried out in the engine compartment or on the engine must
be carried out cautiously.
● When working in the engine compartment, always observe the safety
warnings ⇒ page 230.
● When the engine is warm or hot, the cooling system is pressurised!
Do not unscrew the cap on the expansion tank when the engine is hot.
This is a burn injury risk.
CAUTION
● When mixed with other additives the colour of G12 will change to brown.
If this occurs you should have the coolant changed immediately. Failure to
do so will result in engine damage!
● If a lot of coolant fluid has been lost, wait for the engine to cool down
before putting in cold coolant. This avoids damaging the engine. Large cool-
ant losses are an indication of leaks in the cooling system. See a special-
ised workshop immediately and have the cooling system checked. Other-
wise, there is a risk of engine damage.

Checking fluid levels
From time to time, the levels of the different fluids in the ve-
hicle must be checked. Never fill with incorrect fluids, other-
wise serious damage to the engine may be caused.
