Vehicle care
Seat belts
Use only clear, lukewarm water and 
soap.
Upholstery
Using aftermarket seat covers or wearing 
clothing that have the tendency to give off 
coloring (e.g. when wet, etc.) may cause 
the upholstery to become permanently 
discolored. By lining the seats with a 
proper intermediate cover, 
contact-discoloration will be prevented.Leather upholstery
Please note that leather upholstery is a 
natural product and is therefore subject 
to a natural aging process. Leather 
upholstery may also react to certain 
ambient influences such as high humidity 
or high temperature by showing wrinkles 
for example.
Wipe leather upholstery with a damp 
cloth and dry thoroughly or clean with 
Mercedes-Benz approved Leather 
Care.Exercise particular care when cleaning 
perforated leather as its underside should 
not become wet.
Wood trims
Dampen cloth using water and use 
damp cloth to clean wood trims in your 
vehicle.
Chrome-plated exhaust tip*
Regular cleaning and care of 
chrome-plated exhaust tips will help 
to maintain their shine and the classy 
appearance.
Use Mercedes-Benz approved Chrome 
Polishing Paste each time the vehicle 
has been washed, especially during the 
winter.
!The seat belts must not be treated with 
chemical cleaning agents. Do not dry the seat 
belts at temperatures above 176°F (80°C) or in 
direct sunlight.
Warning!G
Do not bleach or dye seat belts as this may 
severely weaken them. In a crash they may 
not be able to provide adequate protection.
Warning!G
Only use seat covers which have been 
tested and approved by Mercedes-Benz for 
your vehicle model. Using other seat covers 
may interfere with or prevent the deploy-
ment of the head-thorax air bags. Contact 
an authorized Mercedes-Benz Center for 
availability.
!Wipe with light pressure, to avoid damage to 
the upholstery.
!Do not use solvents like tar remover or 
wheel cleaner nor polishes or waxes as these 
may be abrasive. 
!Do not use alkaline cleaners such as wheel 
cleaners as they could cause corrision.

Where will I find...?
Unscrew the valve insert from the valve 
and allow the air to escape.
Screw the valve insert back into the 
valve.
Screw the valve cap back on the valve.
Pull the protective wrap provided with 
the vehicle tool kit over the spare 
wheel.
Store the spare wheel and the valve 
extractor in the storage compartment 
underneath the trunk floor.
Pierce the protective wrap with retain-
ing screw3.
Secure the spare wheel by turning 
retaining screw3 clockwise.
For information on mounting the spare 
wheel, see “Flat tire” (
page 408).
Spare wheel bolts
1Wheel bolt for light alloy rims
2Wheel bolt for spare wheel with 
collapsible tire (located under plastic 
cover on the outside of spare wheel 
rim)
iIt may take a few minutes for the collapsible 
tire to deflate completely.
!Wheel bolts2 must be used when mount-
ing the spare wheel with collapsible tire. The use 
of any wheel bolts other than wheel bolts2 for 
the spare wheel with collapsible tire will physi-
cally damage the vehicle’s brakes.

Warning!G
The jack is intended only for lifting the 
vehicle briefly for wheel changes. It is not 
suited for performing maintenance work 
under the vehicle.
Never start the engine when the vehicle 
is raised.
Never lie down under the raised vehicle.
!Do not place wheel bolts in sand or dirt. This 
could result in damage to the bolt and wheel hub 
threads.
Warning!G
Inflate collapsible tire only after the wheel is 
properly mounted.
Inflate the collapsible tire using the electric 
pump (
page 418) before lowering the 
vehicle.

Flat tire
MOExtended system*
The MOExtended system allows you to 
continue driving your vehicle even if there 
is a total loss of pressure in one or more 
tires. 
You may only use the MOExtended system 
in conjunction with the Run Flat Indicator* 
(Canada vehicles) (
page 315) or TPMS 
(U. S. vehicles) (
page 317).
!The maximum distance in emergency mode 
depends on the vehicle’s load. It is 30 miles 
(50 km) if the vehicle is partially loaded and 
18 miles (30 km) if the vehicle is fully loaded. 
The point at which the maximum driving distance 
begins in emergency mode is when the warning 
message appears in the multifunction display 
indicating that there is a loss of tire inflation 
pressure. 
Do not exceed the maximum speed of 
50 mph (80 km/h). 
Warning!G
In emergency mode, your vehicle’s driving 
characteristics are diminished in such situa-
tions as:
driving around curves
while braking
while accelerating rapidly
Therefore, your driving style must be adapt-
ed accordingly. Avoid abrupt steering and 
driving maneuvers, as well as driving over 
obstacles (road curbs, potholes, or off-road 
areas). This is especially important if the 
vehicle is heavily loaded.
The emergency driving distance that can be 
achieved greatly depends on the demands 
placed on the vehicle. Depending on speed, 
load, driving maneuvers, road conditions, 
outside temperature, etc., the distance can 
be significantly shorter or, if the vehicle is 
driven cautiously, somewhat longer.
Do not continue driving in emergency mode 
if
you notice knocking sounds
the vehicle starts to shake
smoke develops and you smell rubber
ESP® is intervening continuously
you notice tears on the tire sidewalls
After driving in emergency mode, you must 
have the rims inspected by an authorized 
Mercedes-Benz Center to check if they are 
suitable for further use. The failed tire must 
be replaced in any case.
iWhen replacing individual or all tires on the 
vehicle, make sure only tires marked 
with“MOExtended” are mounted in the size 
specified for your vehicle (
page 442).

442 Technical data
Rims and tires
!Only use tires which have been tested and 
approved by Mercedes-Benz. Tires approved by 
Mercedes-Benz are developed to provide best 
possible performance in conjunction 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 sidewall:
MO = Mercedes-Benz Original 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 
authorized Mercedes-Benz Center.
MOE = Mercedes-Benz Original Extended 
(tires with limited run-flat characteristics) 
original equipment tires
Using tires other than those approved by 
Mercedes-Benz may result in damage that is not 
covered by the Mercedes-Benz Limited 
Warranty.
iFor information on driving with MOExtended 
tires, see “MOExtended system*” (
page 421).
!Using tires other than those approved by 
Mercedes-Benz can have detrimental 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 different tire defor-
mation characteristics that could cause them to 
come into contact with the vehicle body or axle 
parts. Damage to the tires or the vehicle 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 pressures is located on the driver’s door 
B-pillar. Some vehicles may have supplemental 
tire inflation pressure information for driving at 
high speeds (
page 313) or for vehicle loads 
less than the maximum loaded vehicle condition 
(
page 313). If such information is provided, it 
can be found on the placard located on the in-
side 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 
recommendation included with vehicle.
iThe following pages also list the approved 
wheel rim and tire sizes for equipping your 
vehicles with winter tires. Winter tires are not 
available as standard or optional factory 
equipment, but can be purchased from an 
authorized Mercedes-Benz Center.
Depending on vehicle model and the standard or 
optional factory-equipped wheel rim/tire config-
uration on your vehicle (Performance Package, 
Sport Package etc.), equipping your vehicle with 
winter tires approved for your vehicle model may 
also require the purchase of two or four wheel 
rims of the recommended size for use with these 
winter tires. Contact an authorized 
Mercedes-Benz Center for more information.
