Notes on the oil level
GWARNING
Hybrid vehicles: be sure to read the "HYBRID"
supplement. Otherwise, you could fail to
recognize dangers.
Depending on the driving style, the vehicle
consumes up to 0.9 US qts (0.8 l) of oil over
a distance of 600 miles (1,000 km). The oil
Engine compartment459Maintenance and careZ
consumption may be higher than this when
the vehicle is new or if you frequently drive at
high engine speeds.
On vehicles with a 12-cylinder engine, the oil
level can be checked using the on-board
computer. On all other models, the oil
dipstick must be used to check the engine oil
level.
Depending on the engine, the oil dipstick may
be in a different location.
When checking the oil level:
R park the vehicle on a level surface.
R the engine should be switched off for
approximately five minutes if the engine is
at normal operating temperature.
R if the engine is not at normal operating
temperature, e.g. if the engine was only
started briefly: wait about 30 minutes
before carrying out the measurement.Checking the oil level using the oil
dipstick
