Engine compartment
Checking engine oil level with the oil
dipstick
When checking the oil level the vehicle
must

be parked on level ground

be at normal operating temperature

have been stationary for at least
5 minutes with the engine turned offTo check the engine oil level with the oil
dipstick, do the following:
Open the hood (page 242).
Pull out oil dipstick1 (page 247).
Wipe oil dipstick1 clean.
Fully insert oil dipstick1 into the
dipstick guide tube.
Pull out oil dipstick1 again after
approximately three seconds to obtain
accurate reading.
Oil dipstick
The oil level is correct when it is between
the lower (min) and upper (max) mark of
the oil dipstick.
If necessary, add engine oil.
For adding engine oil, see (
page 247).
For more information on engine oil, see the
“Technical data” section (
page 376) and
(
page 377).
For more information on messages in the
multifunction display concerning engine
oil, see the “Practical hints” section
(
page 311).
i
The engine oil level can be checked by
either the oil dipstick or via the multi-
function display in the instrument
cluster (
page 244). The amount of
engine oil needed is shown more
precisely in the multifunction display.
i
The filling quantity between the upper
and lower marks on the oil dipstick is
approximately 2.1 US qt. (2.0 l).

248 Operation
Engine compartment
Screw oil filler cap2 back on filler
neck.
For more information on engine oil, see the
“Technical data” section (
page 376) and
(
page 377).
Transmission fluid level
The transmission fluid level does not need
to be checked. The transmission has a per-
manent supply of automatic transmission
fluid.
If you notice transmission fluid loss or gear
shifting malfunctions, have an authorized
Mercedes-Benz Light Truck Center check
the automatic transmission.
Coolant level
The engine coolant is a mixture of water
and anticorrosion/antifreeze.
When checking the coolant level,

the vehicle must be parked on level
ground.

the engine must be cool. The coolant
level should reach the Cold Level mark
(plastic bridge) in the reservoir.
!
Excess oil must be siphoned or drained
off. It could cause damage to the
engine and catalytic converter not
covered by the Mercedes-Benz Limited
Warranty.Warning!G
In order to avoid any possibly serious burns:

Use extreme caution when opening the
hood if there are any signs of steam or
coolant leaking from the cooling system,
or if the coolant temperature display in-
dicates that the coolant is overheated.

Do not remove pressure cap on coolant
reservoir if coolant temperature is
above 158°F (70°C). Allow engine to
cool down before removing cap. The
coolant reservoir contains hot fluid and
is under pressure.

Using a rag, slowly open the cap approx-
imately 1/2turn to relieve excess pres-
sure. If opened immediately, scalding
hot fluid and steam will be blown out un-
der pressure.

Do not spill antifreeze on hot engine
parts. Antifreeze contains ethylene gly-
col which may burn if it comes into con-
tact with hot engine parts.
