Preparing the vehicle for working in the engine compartment
Checklist
The following steps should always be carried out in the specified order before working in
the engine compartment ⇒:
There are rotating components in the engine compartment that can cause serious injury.
•Never place your hand near these components or in the radiator fan. Touching the
rotary blades can result in serious injuries. The fan is temperature-controlled and can
start automatically, even if the ignition has been switched off and the vehicle key has
been removed from the ignition lock.
•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
poly V-belts, alternator, radiator fan etc., and from the high-voltage ignition system.
Always be particularly careful.
- Always ensure that no body parts, jewellery, ties, loose items of clothing or long
hair can be caught up in rotating engine components. Before starting work,
remove any jewellery and ties, tie up long hair and pull clothes in tightly to avoid
them getting caught in the engine compartment.
- Always take due care and attention when depressing the accelerator. The vehicle
could move, even if the electronic parking brake is applied.
•Always ensure you have not left any objects, such as cleaning cloths and tools, in the
engine compartment. Any forgotten items can cause malfunctions, engine damage and
fires.
WARNING
Additional insulating materials such as covers in the engine compartment could disrupt
the operation of the engine, start fires and lead to severe injuries.
•Never cover the engine with any insulating materials.
WARNING
Service fluids and some materials in the engine compartment are highly flammable and
can cause fires and serious injuries!
•Never smoke in the vicinity of the engine compartment.
•Never work near naked flames or sparks.
•Never spill fluids onto the engine. They could ignite on hot engine components and
hence cause injuries.
•Please note the following when carrying out any work on the fuel system or the
electrical system:
- Always disconnect the 12-volt vehicle battery. Ensure that the vehicle is
unlocked when the 12-volt vehicle battery is disconnected as otherwise the anti-
theft alarm will be activated.
- Never work in the direct proximity of heating systems, water heaters or any other
open flames.
•Always have a fully functional and tested fire extinguisher to hand.
WARNING
When topping up or changing service fluids, 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.

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

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.

(MAXyfPDUN.
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 wateryfEXWIRUH[DPSOHEURZQLQVWHDG - 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

•Always check the tyre pressure when the tyres are cold. The specified tyre pressure applies to
cold tyres. Tyre pressure is always higher in warm tyres than it is in cold tyres. For this reason,
never reduce the pressure in warm tyres to adjust the tyre pressure.
•Always adjust the tyre pressure to the load level ⇒ Fig. 236\b.
•After adjusting the tyre pressures, always screw the caps onto the valves and observe the
information on the tyre monitoring system ⇒ Tyre monitoring systems.
•Always use the tyre pressure specified on the sticker. Never exceed the maximum tyre pressure
which is given on the sidewall of the tyre
Underinflated tyres will result in increased fuel consumption.
Tread depth and wear indicators
Fig. 238 Tyre tread: wear indicators.
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Tread depth
In most countries, the minimum tread depth required by law is 1.6 mm (measured in the tread
grooves next to the tread wear indicatorsyfQRWHDQ\FRXQWU\VSHFLILFUHJXODWLRQV7KHW\UHVVKRXOG
have the same tread depth, at the minimum on each axle ⇒.
Observe any country-specific legal requirements relating to the permissible minimum tread depths
for winter and all-year tyres ⇒ Winter tyres.
Tread wear indicator in tyres
The tread wear indicators show if a tyre is worn down. The tyre must be replaced at the latest when
the tread depth is just down to the tread wear indicator.
The bottom of the tyre tread has 1.6 mm high tread wear indicators ⇒ Fig. 238. Markings on the
tyre sidewall indicate the position of the tread wear indicators ⇒ Fig. 238.
Incorrect tyre pressure may cause the tyre to suddenly lose pressure or burst while the
vehicle is in motion. This can cause serious accidents and fatal injuries.
•If the tyre pressure is too low, it is possible that the tyre temperature will increase to
such an extent when driving that the tread peels off and the tyre bursts.
•Fast speeds or overloading of the vehicle can cause overheating, sudden tyre damage
including tyre bursts and ripping of the tread surface and thus to a loss of control of
the vehicle.
•If the tyre pressure is too low, the tyres will wear prematurely and the car will not
handle well.
•Check tyre pressures regularly, at least once a month, and before every long journey.
•All tyres must have the correct tyre pressure to suit the vehicle load.
•Never reduce excess pressure when the tyres are warm.
WARNING
•When attaching the tyre pressure gauge, ensure that you do not position it at an angle
to the valve stem. This can damage the tyre valve.
•Always make sure the valve caps are completely screwed on while driving.
