Where will I find ...?
Setting up the collapsible wheel chock
The collapsible wheel chock serves to ad-
ditionally secure the vehicle, e.g. while
changing the wheel.
1Tilt the plate upward
2Fold the lower plate outward
3Insert the plate

Tilt both plates upward1.

Fold the lower plate outward2.

Spare wheel
Your vehicle is equipped with a spare
wheel with collapsible tire. The spare
wheel is located underneath the cargo
compartment floor.Warning!
G
The dimensions of the spare wheel are dif-
ferent from those of the road wheels. As a
result, the vehicle handling characteristics
change when driving with a spare wheel
mounted.
The spare wheel should only be used tempo-
rarily, and should be replaced with a regular
road wheel as quickly as possible.

514 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
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 510). Some vehicles
may have supplemental tire inflation
pressure information for driving at high
speeds (page 364) or for vehicle
loads less than the maximum loaded
vehicle condition (
page 364). 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.
