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.

Identify the engine oil filler cap and oil dipstick. The engine oil filler opening bears the
symbol on the cap and the oil dipstick has a coloured handle. If you cannot find the cap
and dipstick please contact a qualified workshop.
Pull the dipstick out of the guide tube and wipe it off with a clean cloth.
Insert the oil dipstick into the guide tube again as far as it will go. If there is a marking on
the upper end of the oil dipstick, this marking must fit in the corresponding groove at the
top end of the guide tube when inserting.
After reading off the oil level, push the oil dipstick back into the guide tube as far as it will
go.
Unscrew the engine oil filler opening cap .
Only the engine oil expressly approved by Volkswagen for this engine should be gradually
refilled in small quantities (no more than 0.5 lyf.
In order to avoid overfilling, wait for approximately one minute after each refill step to allow
the engine oil to flow into the oil sump up to the marking on the engine oil dipstick.
Read the engine oil level from the dipstick again before refilling with a further small
quantity of engine oil. Never overfill with engine oil .
After refilling, the engine oil level should be in the middle of area Ⓒ. It should not be above
Ⓒ, in area Ⓑ, and must not reach area Ⓐ .
If too much engine oil has been added unintentionally and the engine oil level is in area Ⓐ,
do not start the engine. Inform a qualified workshop and possibly seek expert assistance.
After refilling, close the engine oil filler opening with the cap.
Insert the oil dipstick into the guide tube as far as it will go. If there is a marking on the

oil level too high. Follow any messages that are shown on the instrument cluster display and
go to a qualified workshop . Ⓑ Do not fill the engine oil . Continue to step 16. Ⓒ Engine oil
level OK. Engine oil can, e.g. in the case of high engine loads , be filled up to the upper limit
of this range. Continue to step 8 or 16. Ⓓ Engine oil level is too low. The engine oil must be
refilled. Continue to step 8.
The engine oil level must never be above area ⇒ Fig. 227Ⓑ. Otherwise oil can be drawn in
through the crankcase breather and escape into the atmosphere via the exhaust system.
Troubleshooting
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Engine oil can ignite if it comes into contact with hot engine components. It can cause
fires, burns and other serious injuries.
•If engine oil is spilt on cold engine parts it can heat up and ignite when the engine is
running.
•Always ensure that the engine oil filler cap is securely tightened after refilling, and that
the dipstick is properly inserted back into the guide tube. This will prevent the engine
oil from draining out on to hot engine components when the engine is running.
WARNING
•If too much engine oil has been added unintentionally and the engine oil level is in area
⇒ Fig. 227Ⓐ, do not start the engine. Inform a qualified workshop and possibly seek
expert assistance. The catalytic converter and the engine could otherwise be damaged.
•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.
NOTICE

Coolant and coolant additives can pollute the environment. Spilt service fluids must be
collected then disposed of properly and in an environmentally responsible way.

(minyf:KHQWKHHQJLQHLVZDUPWKHHQJLQHFRRODQWOHYHOPD\EHVOLJKWO\DERYHWKHPD[LPXP
(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

•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.
NOTICE

Brake fluid can pollute the environment. Any spilt service fluids must be cleaned up and
disposed of properly.
12-volt vehicle battery
Introduction
This chapter contains information on the followingsubjects:
⇒ Checking the electrolyte level of the 12-volt vehicle battery
⇒ Charging, replacing, disconnecting and connecting the 12-volt vehicle battery
⇒ Troubleshooting
The 12-volt vehicle battery is a component of the electrical system and serves to supply power in
the vehicle.
You should only carry out work on the electrical 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 ⇒. All work should be carried out by a qualified workshop. Volkswagen recommends
using a Volkswagen dealership for this purpose.
Location of the 12-volt vehicle battery
Depending on the vehicle equipment level, the 12-volt vehicle battery may be located in the engine
compartment or in the luggage compartment under the luggage compartment floor.

Brake failure or reduced braking effect can be caused by the brake fluid level being too
low or by brake fluid that is too old or unsuitable.
•The brake system and brake fluid level must be checked regularly.
•The brake fluid should be changed regularly.
•Heavy use of the brakes may cause a vapour lock if the brake fluid is left in the system
for too long. Vapour locks reduce levels of braking power, considerably increase
braking distance and can cause the brake system to fail completely.
•Please ensure that the correct brake fluid is used. Only use brake fluid that is explicitly
compliant with VW standard 501 14.
•Any other brake fluid or a low-quality one can affect the functioning of the brakes and
reduce their effectiveness.
•If a brake fluid compliant with VW standard 501 14 is not available, use a high-quality
brake fluid compliant with DIN ISO 4925 CLASS 4 or the US standard FMVSS 116 DOT
4, but only in exceptional circumstances.
•The refilled brake fluid must be new.
WARNING
Brake fluid is toxic.
•In order to reduce the risk of poisoning, never use bottles or other containers to store
brake fluid. There is always a risk of someone drinking from such containers, even if
they are labelled appropriately.
•Brake fluid must always be stored in its original sealed container and kept out of the
reach of children.
WARNING
Brake fluid that has leaked or been spilt can damage the vehicle paintwork, plastic parts
and tyres. Wipe off brake fluid that has leaked or been spilled immediately from all parts of
the vehicle.

First read and observe the introductoryinformation and safety warnings⇒
Introduction
The electrolyte level of the 12-volt vehicle battery should be checked regularly in high-mileage
vehicles, in hot countries and in older 12-volt vehicle batteries. The 12-volt vehicle battery is
otherwise maintenance-free.
Any work on the 12-volt vehicle battery and the electrical system can cause serious
chemical burns, fire or electric shocks. Always read the following warnings and safety
information before carrying out any kind of work:
•Switch off the ignition and all electrical consumers before carrying out any work on the
12-volt vehicle battery and also disconnect the negative cable from the 12-volt vehicle
battery.
•Children should always be kept away from electrolyte and the 12-volt vehicle battery.
•Always wear eye protection and protective gloves.
•Electrolyte is very aggressive. It can burn the skin and can cause blindness. When
working with the 12-volt vehicle battery, ensure that your hands, arms and face in
particular are protected from acid spillages.
•Do not smoke during the work, and never work near naked flames or sparks.
•When handling cables and electrical equipment, avoid generating sparks and
electrostatic charge.
•Never short circuit the battery poles.
•Never use a damaged 12-volt vehicle battery. It can explode. Damaged 12-volt vehicle
batteries must be replaced as soon as possible.
•Damaged or frozen 12-volt vehicle batteries must be replaced as soon as possible.
Discharged 12-volt vehicle batteries can already freeze at temperatures of around
0°C (+32°Fyf.
•In vehicles with the 12-volt vehicle battery in the luggage compartment, ensure that the
breather hose is connected properly to the 12-volt vehicle battery.
WARNING
•Do not expose the 12-volt vehicle battery to direct daylight for an extended period as
the UV rays could damage the battery housing.
•If the vehicle is left standing in cold conditions for a long period, protect the 12-volt
vehicle battery from frost. If it freezes, it will be destroyed.
NOTICE

•Switch off all electrical consumers and the ignition.
•Unlock the vehicle before disconnecting the battery in order to avoid triggering the anti-theft
alarm.
•First disconnect the negative cable and then the positive cable ⇒.
Connecting the 12-volt vehicle battery
•Switch off all electrical consumers and the ignition before reconnecting the 12-volt vehicle
battery.
•First reconnect the positive cable and then the negative cable ⇒.
Various indicator lamps may light up after the 12-volt vehicle battery has been connected and the
ignition is switched on. They will go out if you drive a short distance at a speed of approximately
15 – 20 km/h (10 – 12 mphyf,IWKHLQGLFDWRUODPSVUHPDLQOLWXSWKHYHKLFOHVKRXOGEHFKHFNHGE\D
qualified workshop.
If the 12-volt vehicle battery was disconnected for an extended period, the system may not able to
calculate or correctly display the time when the next service is due ⇒ Instrument cluster. Observe
the maximum permissible service intervals ⇒ Service.
Vehicles with Keyless Access:⇒ Central locking system: if the ignition cannot be switched on after
connecting the 12-volt vehicle battery, lock and unlock the vehicle from the outside. Then try to start
the ignition again. Please contact an expert if the ignition cannot be switched on.
Automatic switch-off for electrical consumers
The intelligent vehicle electrical system management automatically implements a range of
measures to prevent the 12-volt battery from discharging under high loads:
•The idling speed is increased so that the alternator provides more electricity.
•The performance of large electrical consumers may be reduced or they may be switched off
completely.
•The power supply to the 12-volt socket and the cigarette lighter is interrupted temporarily while
the engine is being started.
The vehicle electrical system management function cannot always prevent the 12-volt vehicle
battery from discharging. For example when the ignition is switched on for an extended period with
the engine off, or when the side or parking lights are on when the vehicle is parked for an extended
period.
Battery switch-off in an accident in which the airbag is triggered
In vehicles with 12-volt vehicle battery in the luggage compartment, the electrical connection to the
12-volt vehicle battery is disconnected pyrotechnically in the event of an accident in which the
airbags are triggered. This prevents short-circuiting.
What can cause the 12-volt vehicle battery to discharge?
•Long periods at a standstill in which the engine is not running, especially if the ignition is
switched on.
•The use of electrical consumers when the engine is switched off.
•When the auxiliary heater is being used ⇒ Auxiliary heater and ventilation.
