Tighten the five wheel bolts evenly, fol-
lowing the diagonal sequence illustrat-
ed (1 to5), until all bolts are tight.
Observe a tightening torque of
110 lb-ft (150 Nm).
Before storing the jack in the trunk, it
should be fully collapsed, with handle
folded in.

hicle is raised. Otherwise the vehicle could
fall off the jack.
Warning!
G
Have the tightening torque checked after
changing a wheel. The wheels could come
loose if they are not tightened to a torque of
110 lb-ft (150 Nm).
!You can also store and secure the dam-
aged wheel in the spare wheel well in
the trunk.

410 Technical dataRims and Tires
!
Only use tires which have been tested
and approved for your vehicle by
Mercedes-Benz. Tires approved by
Mercedes-Benz are developed to pro-
vide best possible performance in con-
junction with the driving safety
systems on your vehicle such as ABS or
ESP
®. Tires specially developed for
your vehicle and tested and approved
by Mercedes-Benz can be identified by
finding the following on the tire’s side-
wall:
MO = M
ercedes-Benz O
riginal
equipment tires
AMG vehicles:
Does not apply to all approved tires
on AMG vehicles. For information
on tested and approved tires for
AMG vehicles, contact an autho-
rized Mercedes-Benz Center.
Using tires other than those approved
by Mercedes-Benz may result in dam-
age that is not covered by the
Mercedes-Benz Limited Warranty.!Using tires other than those approved
by Mercedes-Benz can have detrimen-
tal effects, such as
poor handling characteristics
increased noise
increased fuel consumption
Moreover, tires and rims not approved
by Mercedes-Benz may, under load,
exhibit dimensional variations and dif-
ferent tire deformation characteristics
that could cause them to come into
contact with the vehicle body or axle
parts. Damage to the tires or the vehi-
cle may be the result.
iFurther information on tires and rims is
available at any authorized
Mercedes-Benz Center. A placard with
the recommended tire inflation pres-
sures is located on the driver’s door
B-pillar (
page 286). Some vehicles
may have supplemental tire inflation
pressure information for driving at high
speeds (page 293) or for vehicle
loads less than the maximum loaded
vehicle condition (
page 299). If such
information is provided, it can be found
on the placard located on the inside of
the fuel filler flap. The tire inflation
pressure should be checked regularly
and should only be adjusted on cold
tires. Follow tire manufacturer’s main-
tenance recommendation included
with vehicle.

420 Technical dataFuels, coolants, lubricants, etc.Engine oils
Engine oils are specifically tested for their
suitability in our engines and durability for
our service intervals. Therefore, only use
approved engine oils and oil filters
required for vehicles with Maintenance
System (U.S. vehicles) or FSS (Canada
vehicles). For a listing of approved engine
oils and oil filters, refer to the Factory
Approved Service Products pamphlet, or
contact an authorized Mercedes-Benz
Center.
Engine oil additives
Do not blend oil additives with engine oil.
They may damage the engine.
Damage or malfunctions resulting from
blending oil additives are not covered by
the Mercedes-Benz Limited Warranty.Air conditioning refrigerant
R-134a (HFC) refrigerant and special PAG
lubricating oil is used in the air condition-
ing system.
Never use R-12 (CFC) or mineral-based lu-
bricating oil. Otherwise damage to the
system will occur.
Brake fluid
During vehicle operation, the boiling point
of the brake fluid is continuously reduced
through the absorption of moisture from
the atmosphere.
Only brake fluid approved by
Mercedes-Benz is recommended. Your au-
thorized Mercedes-Benz Center will pro-
vide you with additional information.
!Using engine oils and oil filters of
specification other than those express-
ly required for the Maintenance System
(U.S. vehicles) or FSS (Canada vehi-
cles), or changing of oil and oil filter at
change intervals longer than those
called for by the Maintenance System
(U.S. vehicles) or FSS (Canada vehi-
cles) will result in engine damage not
covered by the Mercedes-Benz Limited
Warranty.
Please follow Maintenance System
(U.S. vehicles) or FSS (Canada vehi-
cles) recommendations for scheduled
oil changes. Failure to do so will result
in engine damage not covered by the
Mercedes-Benz Limited Warranty.
Warning!
G
Under extremely strenuous operating condi-
tions, this moisture content can lead to the
formation of bubbles in the system, thus re-
ducing the system’s efficiency.
Therefore, the brake fluid must be replaced
regularly. Refer to your vehicle’s
Maintenance Booklet for replacement.
