Notes on the oil level 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
consumption may be highe rthan 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.

R
using engine oils and oil filters that have
not been specifically approved for the
service system
R replacing engine oil and oil filters after
the interval for replacement specified by
the service system has been exceeded
R using engine oil additives.
! Do not add too much oil. adding too much
engine oil can result in damage to the
engine or to the catalytic converter. Have
excess engine oil siphoned off. Example: engine oil cap
X
Turn cap :counter-clockwise and remove
it.
X Add engine oil.
Vehicles with oil level measurement
function in the on-board computer: observe
the information in the on-board computer
when doing so. Vehicles with an oil
dipstick: if the oil level is at or below the
MIN mark on the dipstick, add 1.1 US qt
(1.0 liters) of engine oil. X
Replace cap :on the filler neck and turn
clockwise.
Ensure that the cap locks into place
securely.
X Check the oil level againw ith the oil
dipstick (Y page 421) or the on-board
computer (Y page 422).

Checking coolant level G
WARNING
In order to avoid any potentially serious burns:
R use extreme caution when opening the
hood if there are any signs of steam or
coolan tleaking from the cooling system, or
if the coolant temperature display indicates
that the coolant is overheated.
R do not remove the pressure cap on the
coolant reservoir if the coolant temperature
is above 158 ‡(70 †). Allow the engine to
cool dow nbefore removing the cap. The
coolant reservoir contains hot fluid and is
under pressure.
R using a rag, slowly turn the cap
approximately 1
/ 2 turn to relieve excess
pressure. If opened immediately, scalding
hot fluid and steam will be blown out under
pressure.
