⇒ Jump starting the vehicle .
If you notice misfiring, loss of power or uneven running when driving, reduce speed immediately and
have the vehicle checked by a qualified workshop ⇒ Troubleshooting . Otherwise unburnt fuel can
enter the exhaust system and escape into the atmosphere. The catalytic converter can also be
damaged by overheating.
The emissions may have a sulphur-like smell even when the exhaust purification system is working
properly.
Particulate filter

Function
⇒ Fuel standards .
⇒ Refuelling .
⇒ Engine oil standards .
⇒ Jump starting the vehicle .
Periodic regeneration
The soot in the particulate filter is burnt off at high temperatures on a periodic basis.
To assist the regeneration of the particulate filter, Volkswagen recommends that you avoid making
only short journeys.
Noises, slight smells and increased engine speeds may occur during regeneration. The radiator fan
may run on while the vehicle is moving or when the engine has been switched off.
During the periodic regeneration process, the yellow indicator lamp does not light up.

With the engine at operating temperature, park the vehicle on a level surface to ensure that the
engine oil reading is correct.
Switch off the engine and wait a few minutes for the engine oil to flow back into the sump.
Open the bonnet In the engine compartment.
Identify the engine oil filler cap and oil dipstick. The engine oil filler opening can be recognised by
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 into the corresponding groove at the top end of the
guide tube upon insertion.

level too high. Observe any messages that are shown on the instrument cluster display or contact a
qualified workshop . Ⓑ Do not fill any engine oil . Continue with 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 with step 8 or 16. Ⓓ Engine oil level is too low. Engine oil must be filled. Continue with
step 8.
After reading off the oil level, push the oil dipstick back into the guide tube as far as it will go.
Unscrew the cap of the engine oil filler opening .
Using only the engine oil approved by Volkswagen expressly for this engine, fill oil gradually in small
amounts (no more than 0.5 l).

The coolant additive is dyed purple. The mixture of water and a coolant additive offers anti-freeze
protection down to -25°C (-13°F), protects the alloy parts in the cooling system against corrosion,
prevents limescale deposits and significantly increases the boiling point of the coolant.
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 ⇒ .
WARNING
Insufficient anti-freeze in the coolant system can cause the engine to break down and cause serious
injuries.
ive used must be sufficient for the lowest
ambient temperature that you expect the vehicle to be exposed to.
Vehicle occupants with inadequate winter clothing could then freeze to death as the heating will
also no longer function.
NOTICE
Never mix genuine coolant additives with other coolants that have not been approved by
Volkswagen.
ts from mixing the purple
coolant additive with distilled water) but for example, brown instead of purple, - G 13 - has been
mixed with an unsuitable coolant additive. The coolant must be changed as soon as possible if this is
the case. Failure to observe this warning can result in serious malfunctions or damage to the engine
and cooling system.
Coolant and coolant additives can pollute the environment. Spilt service fluids must be collected and
then disposed of properly and in an environmentally responsible way.
