Safety notes for working in the engine compartment
Always park the vehicle on a level and stable surface before carrying out any work in the engine
compartment.
The engine compartment of a motor vehicle is a hazardous area. You should only carry out work on
the engine, and in the engine compartment, if you know exactly how to perform the required tasks,
are aware of the general safety procedures and have access to the correct equipment, service
fluids and suitable tools. Failing to carry out work correctly can cause serious injuries ⇒. The
work should be carried out by a qualified workshop if you are uncertain. Volkswagen recommends
using a Volkswagen dealership for this purpose.
Unintentional vehicle movements during service work can cause serious injury.
•Never work underneath a vehicle if it is not secured against rolling away. If you are
working underneath the vehicle while the wheels are on the ground, the vehicle must
be on a level, the wheels chocked, and the vehicle key removed from the ignition lock
as required.
•If you have to work underneath the vehicle, use suitable stands to provide extra
support for the vehicle. The vehicle jack is not sufficient for this task and can fail,
which can lead to serious injuries.
•The start/stop system must have been deactivated.
WARNING
The engine compartment of any motor vehicle is a dangerous area. Serious injuries can be
sustained here.
•The utmost care and attention must be paid when carrying out any work and you must
follow the general safety rules. Never take any risks.
•Never do any work on the engine or in the engine compartment unless you know
exactly how to carry it out. If you are uncertain of what to do, the work should be
carried out by a qualified workshop. Serious injuries can result from work that has not
been carried out properly.
•Never open the bonnet if you see steam or coolant escaping from the engine
compartment. Hot steam or hot coolant can cause serious burns. Always wait until you
can no longer see or hear steam or coolant coming from the engine compartment.
•Always allow the engine to cool down before opening the bonnet.
•Hot parts of the engine or exhaust system can burn the skin.
•Observe the following points before opening the bonnet once the engine has cooled
down:
- Switch on the electronic parking brake and move the selector lever to position P
or move the gear lever to the neutral position.
- Switch off the ignition and remove the vehicle key from the ignition lock.
- Always keep children away from the engine compartment and never leave the
vehicle unattended.

the coolant expansion tank when the engine is hot. Coolant may spray out and cause
serious burns and other injuries.
- Slowly and carefully turn the cap on the coolant expansion tank anticlockwise
while exerting gentle downward pressure on the cap.
- Always protect the face, hands and arms from hot coolant or steam with a large,
thick cloth.
•When refilling, do not spill any service fluids on engine components or on the exhaust
system. The spilt service fluids can start a fire.
WARNING
High voltages in the electrical system can cause electric shocks, burns, serious injuries
and death!
•Never short circuit the electric system. The 12-volt battery could explode.
•Please note the following guidelines to help reduce the risk of an electric shock and
serious injuries while the engine is running or being started:
- Never touch the electrical wiring of the ignition system.
- Never touch the electrical wiring and connections of gas discharge bulbs.
WARNING

Leaking service fluids can pollute the environment. Spilt service fluids must be collected in
suitable containers and disposed of properly and with respect for the environment.
Washer fluid
Fig. 226 In the engine compartment: cap of washer fluid reservoir.
The windscreen washer fluid level should be checked regularly and topped up as necessary.
A filter can be found in the feed throat of the washer fluid reservoir. The filter keeps large dirt
particles away from the windscreen washer jets when refilling. The filter should only be removed for
cleaning. If the filter is damaged or is not present, dirt particles can enter the system and will block
the washer jets.
•Open the bonnet ⇒ In the engine compartment.
•The washer fluid reservoir is identified by the symbol on the cap ⇒ Fig. 226.
•Check whether there is enough windscreen washer fluid in the reservoir.
•To top up, mix clean water (not distilled water) with a washer fluid recommended by
Volkswagen ⇒. Observe the dilution instructions on the packaging.
•At low temperatures, add a special anti-freeze agent so that the fluid cannot freeze ⇒.
Capacities
The washer fluid reservoir has a capacity of between 3 and 5 litres depending on the vehicle
equipment level.
Unsuitable service fluids and consumables, and the incorrect use of these fluids and
consumables, can cause accidents, serious injuries, burns or poisoning.
•Service fluids must be kept in their original sealed container.
•Never store service fluids in empty food containers, bottles or any other non-original
containers as people finding these containers could drink them.
•Keep children away from all service fluids and consumables.
•Always read and follow the information and warnings on the service fluid packaging.
•When using products that give off harmful fumes, always work outdoors or in a well-
ventilated area.
•Never use fuel, turpentine, engine oil, nail varnish remover or other volatile fluids for
vehicle care. They are toxic and highly flammable. They could cause fires and
explosions.
WARNING
•Only use suitable service fluids for refilling. Never use the wrong service fluid. Failure
to observe this warning can result in serious malfunctions and engine damage.
•Optional equipment and other accessories in front of the air inlet reduce the cooling
effect of the coolant. The engine may overheat at high ambient temperatures and high
engine loads.

Engine coolant
Introduction
This chapter contains information on the followingsubjects:
⇒ Coolant specification
⇒ Checking the coolant level and refilling coolant
You should only carry out work on the cooling system if you know exactly how to perform the
required tasks, are aware of the general safety procedures and have access to the correct
equipment, service fluids and suitable tools. Failing to carry out work correctly can cause serious
injuries ⇒. The work should be carried out by a qualified workshop if you are uncertain.
Volkswagen recommends using a Volkswagen dealership for this purpose.
Coolant and coolant additives can pollute the environment. Spilt service fluids must be
collected then disposed of properly and in an environmentally responsible way.
Coolant specification
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The cooling system is filled at the factory with a mixture of specially prepared water and at least
40% coolant additive G 13 (TL-VW 774 J). The coolant additive is dyed purple. This mixture of
water and coolant additive gives the necessary frost protection down to -25°C (-13°F) and protects
the alloy parts of the cooling system against corrosion. The mixture also prevents scaling and
raises the boiling point of the coolant.
In order to protect the coolant system, the proportion of coolant additive must always be at least
40%, even if anti-freeze is not required in warm weather and warm climates.
If greater frost protection is required in very cold climates, the proportion of anti-freeze additive can
be increased. However, the percentage of coolant additive should not exceed 60%, as this would
reduce the frost protection and the cooling effect.
When refilling the coolant, a mixture of distilled water and at least 40% coolant additive - G 13 - or
- G 12 plus-plus - (TL-VW 774 G) (both of which are dyed purple) must be used in order to obtain
the optimum corrosion protection ⇒. Mixing - G 13 - with the coolant additives - G 12 plus - (TL-
VW 774 F), - G 12 - (dyed red) or - G 11 - (dyed blue-green) will significantly decrease the level of
corrosion protection and should therefore be avoided ⇒.
Engine coolant is toxic.
•Engine coolant should only be kept in sealed original containers in a safe place.
•Never store engine coolant in empty food containers, bottles or any other non-original
containers as people finding these containers may then drink the engine coolant.
•The engine coolant must be stored out of the reach of children.
•Please note that the amount of correct coolant additive used must be sufficient for the
lowest ambient temperature that you expect the vehicle to be exposed to.
•Coolant can freeze at extremely cold outside temperatures, causing the vehicle to
break down. Vehicle occupants with inadequate winter clothing could then freeze to
death as the heating will also no longer function.
WARNING

Coolant and coolant additives can pollute the environment. Spilt service fluids must be
collected then disposed of properly and in an environmentally responsible way.
Checking the coolant level and refilling coolant
Fig. 229 In the engine compartment: markings on the coolant expansion tank.
Fig. 230 In the engine compartment: coolant expansion tank cap (illustration).
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The warning lamp for the engine coolant will light up if the engine coolant level is too low.
Preparation
•Park the vehicle on a firm and level surface.
•Allow the engine to cool down ⇒.
•Open the bonnet ⇒ In the engine compartment.
•The coolant expansion tank is identified by the symbol on the cap ⇒ Fig. 230.
Checking the coolant level
•When the engine is cold, check the coolant level on the side markings of the engine coolant
expansion tank ⇒ Fig. 229. The engine coolant level must be between the marks.
•Refill coolant if the liquid level in the coolant expansion tank is below the minimum marking
(min). When the engine is warm, the engine coolant level may be slightly above the maximum
(MAX) mark.
Refilling coolant
•Always protect your face, hands and arms from hot coolant or steam by placing a suitable cloth
on the cap of the coolant expansion tank.
•Unscrew the cap carefully ⇒.
•Refill only new coolant according to the Volkswagen specification ⇒ Coolant specification⇒
.
Insufficient anti-freeze in the coolant system can cause the engine to break down and
cause serious injuries.
•Please note that the amount of correct coolant additive used must be sufficient for the
lowest ambient temperature that you expect the vehicle to be exposed to.
•Coolant can freeze at extremely cold outside temperatures, causing the vehicle to
break down. Vehicle occupants with inadequate winter clothing could then freeze to
death as the heating will also no longer function.
WARNING
Never mix genuine coolant additives with other coolants that have not been approved by
Volkswagen. Mixing other coolants could cause serious damage to the engine and cooling
system.
•If the liquid in the coolant expansion tank is not pink (colouring results from mixing the
purple coolant additive with distilled water) but for example, brown instead, - G 13 - has
been mixed with an unsuitable coolant. The coolant must be changed as soon as
possible if this is the case. Failure to observe this point can result in serious faults or
engine damage.
NOTICE

•Only top up coolant if there is coolant residue in the expansion tank. If this is not observed, the
engine could be damaged. If you cannot see any coolant in the expansion tank do not drive
on. Seek professional assistance.
•If you can see coolant residue in the coolant expansion tank, refill coolant until the level remains
stable.
•The coolant level must be between the marks on the coolant expansion tank ⇒ Fig. 229. Do
not fill above the top edge of the marked area⇒.
•Close the cap tightly.
•If in an emergency you do not have access to the required specification ⇒ Coolant 
specification, do not use any other coolant additive! Instead, initially refill with distilled water⇒
only. Then add the correct proportion of coolant additive as soon as possible ⇒ Coolant 
specification.
Brake fluid
Hot steam or coolant can cause serious burns.
•Never open the bonnet if you can see or hear steam or engine coolant coming out of
the engine compartment. Always wait until you can no longer see or hear escaping
steam or coolant.
•Always allow the engine to cool down completely before carefully opening the bonnet.
Hot components can burn the skin.
•The following points should be noted before opening the bonnet once the engine has
cooled down:
- Switch on the electronic parking brake and move the selector lever to position P
or move the gear lever to the neutral position.
- Switch off the ignition and remove the vehicle key from the ignition lock.
- Always keep children away from the engine compartment and never leave the
vehicle unattended.
•The cooling system is under pressure when the engine is hot. Never open the cap of
the coolant expansion tank when the engine is hot. Coolant may spray out and cause
serious burns and other injuries.
- Turn the cap slowly and very carefully anti-clockwise while exerting gentle
downward pressure on the cap.
- Always protect the face, hands and arms from hot coolant or steam with a large,
thick cloth.
•When refilling, do not spill any service fluids on engine components or on the exhaust
system. The spilt service fluids can start a fire. In certain circumstances, the ethylene
glycol in the engine can catch fire.
WARNING
•Refill only with distilled water. All other types of water can cause corrosion in the
engine due to the chemical components contained therein. This can also lead to engine
failure. If any other type of water than distilled water is refilled, the fluid in the cooling
system should be completely replaced immediately by a qualified workshop.
•Do not fill coolant above the top of the marked area ⇒ Fig. 229. Otherwise the excess
coolant will be pressed out of the cooling system when the engine is hot and could
cause damage.
•If a large amount of coolant has been lost, do not refill the coolant until the engine has
cooled completely. Heavy coolant loss is an indication of leaks in the engine cooling
system. The engine cooling system should be checked by a qualified workshop as
soon as possible. Failure to do so can result in engine damage.
•Do not top up with coolant if there is no more coolant in the coolant expansion tank. Air
could have entered the cooling system. Do not drive on! Seek expert assistance. Failure
to do so can result in engine damage.
•When topping up service fluids, please ensure that you pour the correct service fluids
into the correct openings. The use of incorrect service fluids could result in serious
malfunctions and engine damage.
