Engine oil
Notes on the oil level
Depending on your driving style, the vehicle
consumes up to 0.9 US qt (0.8 liters) of oil per
600 miles (1,000 km). The oil consumption may be higher than this when the vehicle is new or if
you frequently drive at high engine speeds.
Depending on the engine, the oil dipstick may be
in a different location.
It is only possible to correctly measure the oil
level when:
Rthe engine is at normal operating temperature
Rthe vehicle is parked on a level surface
Rthe engine is left running in neutral for at least
30 seconds before switching off
This applies when checking the oil level using
the oil dipstick or on-board computer.
Checking the oil level using the oil dip-
stick
GWARNING
Certain components in the engine compart-
ment, such as the engine, radiator and parts
of the exhaust system, can become very hot.
Working in the engine compartment poses a
risk of injury.
Where possible, let the engine cool down and touch only the components described in the
following.
It is only possible to correctly measure the oil
level with the oil dipstick when the engine is at
normal operating temperature and in a period of
2 to minutes after the engine has been switched
off.
