Inspecting and Replenishing
252
Oil level within range
– You may top up the oil. It is possible that the oil level may then
be within range after doing this.
Oil level within range
– You must top up the oil ⇒page 252. It is sufficient, once this
is done, to keep the oil level is within range .
It is normal for the engine to consume oil. The oil consumption may be as
much as 0.5 l/1 000 km depending on your style of driving and the condi-
tions under which you operate your vehicle. The oil consumption may be
slightly higher than this during the first 5 000 kilometres.
One should therefore check the oil level at regular intervals, preferably
every time after the fuel tank is filled or after driving for long stretches.
We recommend maintaining the oil level within the range if the engine
has been operating at high loads, for example during a lengthy motorway
trip during the summer months, towing a trailer or negotiating a high
mountain pass, but not above this .
The warning light in the instrument cluster* will indicate ⇒page 38,
“Engine oil level* ” whether the oil level is too low. In this case, check
the oil level as soon as possible. Top up with an appropriate quantity of oil.
Caution
•The oil level must on no account extend beyond the range . Danger
of damaging the catalytic converter.
•Do not continue your journey if for some reason it is not possible
under the conditions prevailing to top up with oil. Switch of the engine
and contact and obtain professional assistance from a specialist
garage.
Replenishing engine oil
– Inspecting the engine oil level ⇒page 251.
– Unscrew the cap of the engine oil filler opening.
– Pour in a suitable grade of oil in portions of 0.5 litres ⇒page 250, “Engine oil specifications”.
– Inspect the oil level ⇒page 251.
– 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 248, “Working in
the engine compartment” before working in the engine compart-
ment.
For the sake of the environment
The oil level must on no account be above the range ⇒page 251. Oil
will otherwise 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.

WARNING
There is high risk of having an accident when tow-starting a
vehicle, when for example the towed vehicle runs into the towing
vehicle.
Caution
Vehicles which are fitted with a catalytic converter should not be tow-
started over a distance of more than 50 metres. Unburnt fuel may get into
the catalytic converter and damage it.
Towing in a vehicle fitted with a manual gearbox
Please refer to the notes ⇒page 283.
The car can be towed in with a tow bar or a tow rope or with the front or
rear wheels raised. The maximum towing speed is 50 km/h.
Towing of a vehicle with an automatic gearbox
Please refer to the notes ⇒page 283.
The car can be towed in with a tow bar or a tow rope. Refer at the same
time to the following guidelines:
•Move selector lever into N .
•The maximum towing speed is 50 km/h.
•The maximum permissible towing distance is 50 km. The gear oil
pump does not operate when the engine is not running and the gear would
not be adequately lubricated at higher speeds and over longer towing
distance.
Caution
If the vehicle is towed in by a recovery vehicle, it should only be towed in
with the front wheels raised. If the vehicle is raised at rear, the automatic
gearbox is damaged! (Does not apply to the automatic gearbox DSG).
Note
The vehicle must be transported on a special vehicle or trailer if it is not
possible to tow in the vehicle in the way described or if the towing distance
is greater than 50 km.
