Inspecting and replenishing 188sional assistance from a specialist garage, otherwise it could lead to severe engine
damage.Replenishing engine oil– Inspect the oil level ⇒page 187.
– Unscrew the cap of the engine oil filler opening.
– Wipe off the oil from the sealing surface of the cover and on the coun-
terpart using a clean cloth.
– Pour in a suitable grade of oil in portions of 0.5 litres ⇒page 236.
– Inspect the oil level ⇒page 187.
– Carefully screw on the cap of the filler opening and push the dipstick
in fully.
WARNING
•
Avoid dripping oil onto hot parts of the engine when topping up will oil -
a risk of fire!
•
Read and observe the warning notes ⇒page 185, “Working in the engine
compartment” before working in the engine compartment.For the sake of the environment
The oil level must on no account be above the range ⇒page 187. Oil will other-
wise be drawn in through the crankcase ventilation and may pass through the
exhaust system to atmosphere. The oil may combust in the catalytic converter and
damage it.Changing engine oilThe engine oil must be changed at the intervals stated in the Service schedule or
according to the service interval indicator ⇒page 20.
WARNING
•
Only carry out the engine oil change, if you have the required profes-
sional knowledge!
•
Read and observe the warning notes ⇒page 185, “Working in the engine
compartment” before working in the engine compartment.
•
Let the engine cool down - risk of burning from hot oil.
•
Wear an eye protection - risk of caustic burns due to oil splashes.
•
Oil is toxic! Store old oil in a safe place out of the reach of children and
unauthorized persons until you dispose of it properly.Caution
You must not pour any additives into the engine oil - risk of engine damage!
Damage, which results from such product, are excluded from the warranty.
For the sake of the environment
•
You must on no account pour oil into the ground or into the sewage system.
•
In view of the problems involved in properly disposing of old oil, the necessary
special tools and the knowledge required for such work, we recommend that you
have the oil and oil filter change carried out by a specialist garage.Note
After your skin has come in contact with the oil, you must thoroughly wash your
skin.

Cooling systemCoolant
The job of the coolant is to cool the engine.The cooling system does not require any maintenance under normal operating
conditions. The coolant consists of water with a concentration of coolant additive
of 40 %. This mixture not only provides antifreeze protection down to -25°C but
also protects the cooling and heating system from corrosion. It also prevents the
formation of scale and significantly increases the boiling point of the coolant.
You must therefore not reduce the concentration of antifreeze agent in the coolant
by adding water, also not during the summer months or in countries with a warm
climate. The concentration of coolant additive in the coolant must be at least
40%.
You can increase the amount of antifreeze in the coolant if a higher concentration
of antifreeze is necessary for climatic reasons but only up to 60% (antifreeze
protection down to approx. -40°C). The antifreeze protection tails off above that
concentration.
Vehicles exported to countries with a cold climate (e.g. Sweden, Norway, Finland)
are already factory-filled with a coolant which offers antifreeze protection down to
about -35°C. In these countries the concentration of coolant additive should be at
least 50 %.
Coolant
The cooling system is factory-filled with coolant (purple in colour), which complies
with the specification TL-VW 774 G.
We recommend that you use the antifreeze agent G12 PLUS - PLUS (purple in
colour) for topping up the system.
We recommend that you contact a specialist garage if you have any questions
regarding the coolant or if you wish to fill up with a different coolant.
A specialist garage can also supply you with the correct coolant additives.
Caution
•
Other coolant additives may cause operational problems which, in partic-
ular, involves significantly reducing the anticorrosion effect.
•
Any faults or problems resulting from corrosion may cause a loss of
coolant and, as a consequence of this, result in major engine damage.
Inspecting the coolant levelThe coolant expansion bottle is located in the engine compartment on
the right.
– Switch the engine off.
– Open the bonnet ⇒ in “Working in the engine compartment” on
page 185.
– Check the level of coolant in the coolant expansion bottle ⇒fig. 179.
The coolant level when the engine is cold must lie between the “MIN”
and “MAX” markings. The level may also rise slightly above the
“MAX” marking when the engine is warm.
