WARNING
Only change the engine oil yourself if you have the specialist knowledge
required!
● Before opening the bonnet, read and observe the warnings
⇒ page 251.
● Wait for the engine to cool down. Hot oil may cause burn injuries.
● Wear eye protection to avoid injuries, such as acid burns, caused by
splashes of oil.
● When removing the oil drain plug with your fingers, keep your arm
horizontal to help prevent oil from running down your arm.
● Wash your skin thoroughly if it comes into contact with engine oil.
● Engine oil is poisonous! Used oil must be stored in a safe place out of
the reach of children.
CAUTION
No additives should be used with engine oil. This could result in engine
damage. Any damage caused by the use of such additives would not be
covered by the factory warranty.
For the sake of the environment
● Because of the disposal problems, the necessary special tools and spe-
cialist knowledge required, we recommend that you have the engine oil and
filter changed by a Technical Service.
● Never pour oil down drains or into the ground.
● Use a suitable container when draining the used oil. It must be large
enough to hold all the engine oil. Cooling system
Engine coolant specifications
The engine cooling system is supplied from the factory with a specially trea-
ted mixture of water and, at least, 40 % of the additive G 13 (TLVW 774 J).
The engine coolant additive is recognisable by its purple colour. This mix-
ture of water and additive gives the necessary frost protection down to
-25°C (-13 °F) and protects the light alloy parts of the cooling system
against corrosion. It also prevents scaling and considerably raises the boil-
ing point of the coolant.
To protect the engine cooling system, the percentage of additive must al-
ways be at least 40 %, even in warm climates where anti-freeze protection is
not required.
If greater frost protection is required in very cold climates, the proportion of
additive can be increased. However, the percentage of additive should not
exceed 60 %, as this would reduce the frost protection and, in turn, de-
crease the cooling capacity.
When the coolant is topped up, use a mixture of distilled water and, at
least, 40 % of the G 13 or G 12 plus-plus (TL-VW 774 G) additive (both are
purple) to obtain an optimum anticorrosion protection ⇒ 
. The mixture of
G 13 with G 12 plus (TL-VW 774 F), G 12 (red) or G 11 (green-blue) engine
coolants will significantly reduce the anticorrosion protection and should,
therefore be avoided ⇒

Checking and refilling levels
Wear eye protection.
Battery acid is very corrosive and caustic. Wear protective gloves
and eye protection. In the event of electrolyte splashes, rinse off
with plenty of water.
Fires, sparks, open flames and smoking are prohibited.
The battery should only be charged in a well-ventilated zone. Risk
of explosion!
Keep children away from acid and batteries!
WARNING
● When repairing or working on the electrical system, proceed as fol-
lows:
● 1. Remove the key from the ignition. The negative cable on the bat-
tery must be disconnected.
● 2. When the repair is finished, reconnect the negative pole of the bat-
tery.
● Switch off all electrical consumers before reconnecting the battery.
Reconnect first the positive cable and then the negative cable. Never re-
verse the polarity of the connections. This could cause an electrical fire.
● Ensure that the vent hose is always connected to the battery.
● Never use damaged batteries. This could cause an explosion! Replace
a damaged battery immediately.
CAUTION
● Never disconnect the battery if the ignition is switched on or if the en-
gine is running. This could damage the electrical system or electronic com-
ponents. Charging the battery
Terminals for charging the battery are fitted in the engine
compartment.
–
Note the warnings ⇒ 
in Important safety warnings for han-
dling a vehicle battery on page 261 and ⇒ .
– Switch off all electrical equipment. Remove the ignition key.
– Raise the bonnet ⇒ page 252.
– Open the battery cover.
– Connect the charger clamps as described to the positive pole of
the battery (+) and, exclusively to an earth on the bodywork
(–).
– Only use a charger which is compatible for use with 12 V nomi-
nal voltage batteries. The charge must not exceed a voltage of
15 V.
– Now connect the battery charger to the power socket and switch
on.
– After charging the battery: switch off the battery charger and
disconnect the power socket cable.
– Finally disconnect the charger cables from the battery.
– Replace the battery cover correctly.
– Close the bonnet ⇒ page 253.
Important: Before you charge the battery make sure you read the manufac-
turer's instructions for using the battery charger. 
