Information about oil consumption
!
If the vehicle is predominantly used for
short-distance driving, this could lead to a
malfunction in the automatic cleaning func- tion for the diesel particle filter. As a result,
fuel may accumulate in the engine oil and
cause engine failure.
Therefore, if you mainly drive short distan-
ces, you should drive on a highway or on
rural roads for 20 minutes every 310 miles
(500 km). This ensures sufficient regener-
ation of the diesel particle filter.
Depending on the driving style, the vehicle
consumes a maximum of 1.0 US qt (1.0 l) of
engine oil over a distance of 620 miles
(1000 km).
Oil consumption may be higher if:
R the vehicle is new.
R you mainly operate the vehicle under ardu-
ous operating conditions.
R you frequently drive at high engine speeds.
Regular maintenance is one of the precondi-
tions for moderate rates of consumption.
You can only estimate the oil consumption
after you have driven a considerable distance.
Check the engine oil level on a regular basis,
e.g. weekly or each time you refuel
(Y page 250). Transmission and power steering oil
