64 Safety and Security
Occupant safety
Safety guidelines for the seat belt,
emergency tensioning device and
air bag In cases of other frontal impacts,
angled impacts, roll-overs, other side
impacts, rear collisions, or other acci-
dents, the air bags will not be activat-
ed. The driver and passengers will then
be protected by the fastened seat
belts.
We caution you not to rely on the
presence of the air bags in order to
avoid wearing your seat belt.
Your vehicle was originally equipped
with air bags that are designed to acti-
vate in certain impacts exceeding a
preset threshold to reduce the poten-
tial and severity of injury. It is important
to your safety and that of your passen-
gers that you replace deployed air bags
and repair any malfunctioning air bags
to make sure that the vehicle will con-
tinue to provide supplemental crash
protection for occupants.
Warning!G

Damaged seat belts or belts that were
highly stressed in an accident must be
replaced and their anchoring points
must also be checked. Only use belts in-
stalled or supplied by an authorized
Mercedes-Benz Center.

Air bags and emergency tensioning
devices (ETDs) are designed to function
on a one-time-only basis. An air bag or
ETD that was activated must be
replaced.

No modifications of any kind may be
made to any components or wiring of
the SRS. This includes changing or re-
moving any component or part of the
SRS, the installation of additional trim
material, badges, etc. over the steering
wheel hub, passenger front air bag
cover, outboard sides of the front seat
backrests, door trim panels, or door
frame trims, and installation of addition-
al electrical/electronic equipment on or
near SRS components and wiring. Keep
area between air bags and occupants
free from objects (e.g. packages, purs-
es, umbrellas, etc.).

Do not pass belts over sharp edges.
They could tear.

Do not make any modification that could
change the effectiveness of the belts.

Do not bleach or dye seat belts as this
may severely weaken them. In a crash
they may not be able to provide ade-
quate protection.

305 Operation
Tires and wheels
Tires and wheels
See an authorized Mercedes-Benz Center
for information on tested and
recommended rims and tires for summer
and winter operation. They can also offer
advice concerning tire service and
purchase.Important guidelines

Only use sets of tires and rims of the
same type and make.

Tires must be of the correct size for the
rim.

Break in new tires for approximately
60 miles (100 km) at moderate
speeds.

Regularly check the tires and rims for
damage. Dented or bent rims can
cause tire inflation pressure loss and
damage to the tire beads.

If vehicle is heavily loaded, check tire
inflation pressure and correct as
required.

Do not allow your tires to wear down
too far. Adhesion properties on wet
roads are sharply reduced at tread
depths under
1/8in (3 mm).

When replacing individual tires, you
should mount new tires on the front
wheels first (on vehicles with
same-sized wheels all around).
Warning!G
Replace rims or tires with the same designa-
tion, manufacturer and type as shown on the
original part. See an authorized
Mercedes-Benz Center for further informa-
tion. If incorrectly sized rims and tires are
mounted:

The wheel brakes or suspension
components can be damaged.

The operating clearance of the wheels
and the tires may no longer be correct.
Warning!G
Worn, old tires can cause accidents. If the
tire tread is badly worn, or if the tires have
sustained damage, replace them.
When replacing rims, only use genuine
Mercedes-Benz wheel bolts specified for the
particular rim type. Failure to do so can
result in the bolts loosening and possibly an
accident.
Retreaded tires are not tested or recom-
mended by Mercedes-Benz, since previous
damage cannot always be recognized on re-
treads. The operating safety of the vehicle
cannot be assured when such tires are used.

321 Operation
Tires and wheels
Overinflated tires
Overinflated tires can:

adversely affect handling
characteristics

cause uneven tire wear

be more prone to damage from road
hazards

adversely affect ride comfort

increase stopping distance
Tire labeling
Besides tire name (sales designation) and
manufacturer name, a number of markings
can be found on a tire.
Following are some explanations for the
markings on your vehicle’s tires:1Uniform Quality Grading Standards
(
page 329)
2DOT, Tire Identification Number (TIN)
(
page 326)
3Maximum tire load (
page 327)
4Maximum tire inflation pressure
(
page 328)
5Manufacturer
6Tire ply material (
page 331)
7Tire size designation, load and speed
rating (
page 322)
8Load identification (
page 325)
9Tire name
Warning!G
Follow recommended tire inflation
pressures.
Do not overinflate tires. Overinflated tires
can adversely affect handling and ride
comfort, wear unevenly, increase stopping
distance, and result in sudden deflation
(blowout) because they are more likely to
become punctured or damaged by road
debris, potholes etc.

323 Operation
Tires and wheels
Rim diameter
The rim diameter4 (
page 322) is the
diameter of the bead seat, not the
diameter of the rim edge. Rim diameter is
indicated in inches (in).
Tire load rating
The tire load rating5 (
page 322) is a
numerical code associated with the
maximum load a tire can support.
For example, a load rating of 91 corre-
sponds to a maximum load of 1 356 lbs
(615 kg) the tire is designed to support.
See also “Maximum tire load”
(
page 327) where the maximum load as-
sociated with the load index is indicated in
kilograms and lbs.For additional information on tire load
rating, see “Load identification”
(
page 325).
Warning!G
The tire load rating must always be at least
half of the GAWR (
page 332) of your vehi-
cle. Otherwise, tire failure may be the result
which may cause an accident and/or seri-
ous personal injury to you or others.
Always replace rims and tires with the same
designation, manufacturer and type as
shown on the original part.
Warning!G
Do not overload the tires by exceeding the
specified load limit or vehicle capacity
weight as indicated on the placard located
on the driver’s door B-pillar. Overloading the
tires can overheat them, possibly causing a
blowout. Overloading the tires can also
result in handling or steering problems, or
brake failure.
i
Tire load rating5 (page 322) and
tire speed rating6 (
page 322) are
also referred to as “service descrip-
tion”.

335 Operation
Tires and wheels
Rotating tires
Tire rotation can be performed on vehicles
with tires of the same dimension all
around. If your vehicle is equipped with
tires of the same dimension all around,
tires can be rotated, observing a a
front-to-rear rotation pattern that will
maintain the intended rotation (spinning)
direction of the tire (
page 308).
In some cases, such as when your vehicle
is equipped with mixed-size tires (different
tire dimension front vs. rear), tire rotation
is not possible.If applicable to your vehicle’s tire configu-
ration, tires can be rotated according to
the tire manufacturer’s recommended in-
tervals in the tire manufacturer’s warranty
pamphlet located in your vehicle literature
portfolio. If none is available, tires should
be rotated every 3 000 to 6 000 miles
(5 000 to 10 000 km), or sooner if neces-
sary, according to the degree of tire wear.
The same rotation (spinning) direction
must be maintained (
page 308).
Rotate tires before the characteristic tire
wear pattern becomes visible (shoulder
wear on front tires and tread center wear
on rear tires).
Thoroughly clean the mounting face of
wheels and brake disks, i.e. the inner side
of the wheels/tires, during each rotation.
Check for and ensure proper tire inflation
pressure.For information on wheel change, see the
“Practical hints” section (
page 380) and
(
page 404).
Warning!G
Rotate front and rear wheels only if the tires
are of the same dimension.
If your vehicle is equipped with mixed-size
tires (different tire dimensions front vs.
rear), tire rotation is not possible.
Warning!G
Have the tightening torque checked after
changing a wheel. Wheels could become
loose if not tightened with a torque of
80 lb-ft (110 Nm).
Only use genuine Mercedes-Benz wheel
bolts specified for your vehicle’s rims.

346 Operation
Vehicle care
Light alloy wheels
If possible, clean wheels once a week.
Use Mercedes-Benz approved Wheel
Care, a soft bristle brush and a strong
spray of water for cleaning the light al-
loy wheels.
Plastic and rubber parts
Use a gentle dishwashing detergent or
mild detergent for delicate fabrics as a
washing solution.
Instrument cluster and cup holders
Use a gentle dishwashing detergent or
mild detergent for delicate fabrics as a
washing solution.
Wipe with a cloth moistened in a luke-
warm solution.Hard plastic trim items
Use Mercedes-Benz approved Interior
Care, a soft, lint-free cloth and apply
with light pressure.
Steering wheel and gear selector lever
Wipe with a damp cloth and dry thor-
oughly or clean with Mercedes-Benz
approved Leather Care.
Carpets
Use Mercedes-Benz approved Carpet
and Fabric Care for cleaning the car-
pets.
!
Only use acid-free cleaning materials.
Acid may cause corrosion or damage
the clear coat.
!
The vehicle should not be parked for an
extended period of time immediately
after it has been cleaned, especially not
after the wheel rims have been cleaned
with wheel rim cleaner. Wheel rim
cleaners can lead to increased corro-
sion of the brake disks and brake pads.
Therefore, the vehicle’s brake system
should always be warmed-up before it
is parked after cleaning. To do so,
please drive your vehicle for several
minutes to allow the brakes to dry.
When applying Mercedes-Benz ap-
proved Tire Care and Mercedes-Benz
approved Wheel Care products, take
care not to spray them on the brake
disks.
!
Do not use oil or wax on these parts.
!
To prevent scratches, do not use scour-
ing agents.

347 Operation
Vehicle care
Headliner and shelf below rear window
Use a soft bristle brush or a dry-sham-
poo cleaner in case of excessive dirt.
Seat belts
Only use 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 dis-
colored. By lining the seats with a proper
intermediate cover, contact-discoloration
will be prevented.
Leather upholstery
Wipe leather upholstery with a damp
cloth and dry thoroughly or clean with
Mercedes-Benz approved Leather
Care.
Exercise particular care when cleaning per-
forated leather as its underside should not
become wet.MB Tex upholstery
Use Mercedes-Benz approved Interior
Care onto a soft, lint-free cloth and ap-
ply with light pressure for cleaning the
upholstery.
Wood trims
Dampen cloth using water and use
damp cloth to clean wood trims in your
vehicle.!
The webbing must not be treated with
chemical cleaning agents. Do not dry
the webbing 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.
!
Do not use solvents like tar remover or
wheel cleaner nor polishes or waxes as
these may be abrasive.
