WARNING
All work on the engine or in the engine compartment, e.g. checking and
refilling fluids, involves the danger of injury and scalding as well as the
risk of accident or fire.
● Never open the bonnet if you see steam, smoke or coolant escaping
from the engine compartment. Otherwise, there is a risk of sustaining
burns. Wait until no more steam or coolant is emitted, then allow the en-
gine to cool before carefully opening the bonnet.
● Switch off the engine and remove the key from the ignition.
● Apply the handbrake and move the gear lever to neutral or selector
lever to position P.
● Keep children away from the vehicle.
● Never touch hot engine parts. There is a risk of burns.
● Never spill liquids on a hot engine or on a hot exhaust gas system.
This is a fire hazard.
● Avoid causing short-circuits in the electrical system, particularly at
the points where the jump leads are attached ⇒ page 247. The battery
could explode.
● Never touch the radiator fan. It is temperature controlled and could
start automatically, even when the engine has been switched off and the
key removed from the ignition!
● Do not unscrew the cap on the expansion tank when the engine is
hot. If the coolant is hot, the cooling system will be pressurised!
● Protect face, hands and arms by covering the cap with a large, thick
cloth to protect against escaping coolant and steam.
● Always make sure you have not left any objects, such as cleaning
cloths and tools, in the engine compartment.
● If you have to work underneath the vehicle, you must use suitable
stands additionally to support the vehicle, there is a risk of accident!. A
hydraulic jack is insufficient for securing the vehicle and there is a risk of
injury.WARNING (Continued)
● If any work has to be performed when the engine is started or with
the engine running, there is an additional, potentially fatal, safety risk
from the rotating parts, such as the drive belts, alternator, radiator fan,
etc., and from the high-voltage ignition system. You should also observe
the following points:
–Never touch the electrical wiring of the ignition system.
– Ensure that jewellery, loose clothing and long hair do not get trap-
ped in rotating engine parts. Danger of death. Before starting any
work remove jewellery, tie back and cover hair, and wear tight-fitting
clothes.
– Never accelerate with a gear engaged without taking the necessary
precautions. The vehicle could move, even if the handbrake is ap-
plied. Danger of death.
● If work has to be carried out on the fuel system or on electrical com-
ponents, you must observe the following safety notes in addition to the
above warnings:
–Always disconnect the battery. The vehicle must be unlocked when
this is done, otherwise the alarm will be triggered.
– Do not smoke.
– Never work near naked flames.
– Always have a fire extinguisher on hand.
CAUTION
When topping up service fluids, make sure not to mistake them. Using the
wrong fluids could cause serious malfunctions and engine damage!
For the sake of the environment
Service fluids leaks are harmful to the environment. For this reason you
should make regular checks on the ground underneath your vehicle. If you
find spots of oil or other fluids, have your vehicle inspected in a specialised
workshop.

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 G 12++ or an additive with the specification TT-VW
774 G (known for its purple colour). This mixture gives the necessary frost
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
coolant.
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 G 12++ can be increased. However, the percent-
age 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% coolant additive will give frost 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 G 12++ 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.
● If additive G12++ is not available, this can be mixed with G12+, bearing
in mind that the protection against corrosion will be reduced.
Checking the coolant level and topping up
The correct coolant level is important for fault-free function-
ing of the engine cooling system.
