Only use tires which have been specifi-
cally developed for your vehicle and
tested and approved 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
MOE = M
ercedes-Benz O
riginal
E
xtended (tires with limited run-flat
characteristics) original equipment
tires
Using tires other than those approved
by Mercedes-Benz may result in dam-
age that is not covered by the
Mercedes-Benz Limited Warranty.
iFor information on driving with
MOExtended tires*, see
“MOExtendedsystem” (
page 312).
!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. Some vehicles may have sup-
plemental tire inflation pressure infor-
mation for driving at high speeds
(page 307) or for vehicle loads less
than the maximum loaded vehicle con-
dition. 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 maintenance recom-
mendation included with vehicle.
