254 OperationEngine compartmentOil dipstickThe engine oil level is correct when it is
between lower mark (min) and upper mark
(max) of the oil dipstick.
Top up the engine oil if necessary.Adding engine oil
Using a rag, unscrew filler cap2 from
filler neck.
Add engine oil as required. Be careful
not to overfill with oil.Mercedes-Benz recommends
MOBIL 1 OIL. Use the MB sheet number
229.3 and only SAE 5W-50 engine oils.
MB sheet numbers are printed on the out-
side of oil containers.
Be careful not to spill any oil when adding.
Avoid environmental damage caused by oil
entering the ground or water.
Screw the filler cap back on filler neck.
You will find further information about en-
gine oil in the “Technical data” section
(
page 395) and (
page 393).
Transmission fluid level
The transmission fluid level does not need
to be checked. If you notice transmission
fluid loss or gear shifting malfunctions,
have an authorized Mercedes-Benz Center
check the transmission.
i
The filling quantity between the upper and
lower marks on the oil dipstick is approximately
2.1 US qt (2.0 l).
Warning!
G
The filler cap on the filler neck could be hot.
Use a rag when you unscrew the filler cap.
Otherwise you could burn yourself.!
Only use approved engine oils and oil filters
required for vehicles with Maintenance System.
For a listing of approved engine oils and oil fil-
ters, contact an authorized Mercedes-Benz Cen-
ter or visit www.mbusa.com (USA only).
Using engine oils and oil filters of specification
other than those expressly required for the Main-
tenance System, or changing of oil and oil filter
at change intervals longer than those called for
by the Maintenance System will result in engine
or emission control system damage not covered
by the Mercedes-Benz Limited Warranty.
!
Excess oil must be siphoned or drained off.
It could cause damage to the engine or emission
control system not covered by the
Mercedes-Benz Limited Warranty.
398 Technical dataFuels, coolants, lubricants, etc.In areas where carbon deposits may be
encountered due to lack of availability of
gasolines which contain these additives,
Mercedes-Benz recommends the use of
additives approved by us for use on
Mercedes-Benz vehicles. Contact an au-
thorized Mercedes-Benz Center or visit
www.mbusa.com (USA only) for a listing of
approved product(s). Follow directions on
product label.
Do not blend other fuel additives with fuel.
This only results in unnecessary cost and
may be harmful to engine operation.
Coolants
The engine coolant is a mixture of water
and anticorrosion/antifreeze, which pro-
vides:
corrosion protection
freeze protection
boiling protection (by increasing the
boiling point)
The cooling system was filled at the factory
with a coolant providing freeze protection
to approximately -35°F (-37°C) and
corrosion protection.
If the antifreeze mixture is effective to
-35°F (-37°C), the boiling point of the cool-
ant in the pressurized cooling system is
reached at approximately 266°F (130°C).The coolant solution must be used year
round to provide the necessary corrosion
protection and increase in the boil-over
protection. Refer to Maintenance Booklet
for replacement interval.
Coolant system design and coolant used
determine the replacement interval. The
replacement interval published in the
Maintenance Booklet is only applicable if
MB 325.0 Anticorrosion/Antifreeze solu-
tion or other Mercedes-Benz approved
products of equal specification are used to
renew the coolant concentration or bring it
back up to the proper level.
For information on other Mercedes-Benz
approved products of equal specification,
contact an authorized Mercedes-Benz
Center or visit www.mbusa.com
(USA only).
!
Damage or malfunction resulting from poor
fuel quality or from blending additional fuel
additives other than those tested and approved
by us for use on Mercedes-Benz vehicles are not
covered by the Mercedes-Benz Limited Warranty
or by any pre-owned or Extended Limited war-
ranties.
!
Add premixed coolant solution only. Adding
water and MB 325.0 Anticorrosion/Antifreeze
separately from each other, could cause engine
damage not covered by the Mercedes-Benz
Limited Warranty.
