68 Safety and Security
Occupant safety
Safety guidelines for the seat belt,
Emergency Tensioning Device and
air bagiAir bags are designed to activate only in cer-
tain frontal impacts (front air bags, driver-side
knee bag), side impacts (side impact and window
curtain air bags) which exceed preset thresholds
and in certain rollovers (window curtain
air bags). Only during these events will they pro-
vide their supplemental protection.
The driver and passenger should always wear
their seat belts. Otherwise it is not possible for
the air bags to provide their supplemental pro-
tection.
In case of other types of impacts and impacts be-
low air bag deployment thresholds, air bags will
not be deployed. The driver and passenger will
then be protected to the extent possible by a
properly fastened seat belt. A properly fastened
seat belt is also needed to provide the best pro-
tection in a rollover.
We caution you not to rely on the presence of the
air bags in order to avoid wearing your seat belt.
It is important to your safety and that of your pas-
sengers that you replace deployed air bags and
repair any malfunctioning air bags to make sure
that the vehicle will continue to provide supple-
mental crash protection for occupants.
Warning!G

Damaged seat belts or seat belts that
were highly stressed in an accident
must be replaced and their anchoring
points must also be checked. Use only
seat belts installed or supplied by an au-
thorized Mercedes-Benz Center.

Air bags and Emergency Tensioning
Devices (ETDs) contain Perchlorate ma-
terial, which may require special han-
dling and regard for the environment.
Check with your local government’s dis-
posal guidelines. California residents,
see http://www.dtsc.ca.gov/Hazard-
ousWaste/Perchlorate/index.cfm.

Air bags and Emergency Tensioning De-
vices (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, front 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 seat belts over sharp edges.
They could tear.

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

293 Operation
Tires and wheels
Tires and wheels
Contact an authorized Mercedes-Benz
Center for information on tested and rec-
ommended rims and tires for summer and
winter operation. They can also offer ad-
vice 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 re-
quired.

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

The wheels on the front and rear axles
are different. For this reason, pay at-
tention to the markings on the inside of
the wheel rims. Wheels marked “REAR
AXLE ONLY” on the inside of the rim
may only be fitted on the rear axle.

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 compo-
nents can be damaged.

The correct operating clearance of the
wheels and the tires are no longer guar-
anteed.
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 re-
sult 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.

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 Tire Quality Grading Standards

316 Operation
Tires and wheels
Tire load rating
The tire load rating5 (
page 314) 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 320) 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 318).Tire speed rating
The tire speed rating6 (
page 314)
indicates the approved maximum speed
for the tire.
Warning!G
The tire load rating must always be at least
half of the GAWR (
page 324) of your
vehicle. Otherwise, tire failure may be the
result which may cause an accident and/or
serious 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 total load limit as indicated on the
Tire and Loading Information placard locat-
ed on the driver’s door B-pillar. Overloading
the tires can overheat them, possibly caus-
ing a blowout. Overloading the tires can also
result in handling or steering problems, or
brake failure.
iTire load rating5 (page 314) and tire
speed rating6 (
page 314) are also referred
to as “service description”.
Warning!G
Even when permitted by law, never operate
a vehicle at speeds greater than the
maximum speed rating of the tires.
Exceeding the maximum speed for which
tires are rated can lead to sudden tire
failure, causing loss of vehicle control and
possibly resulting in an accident and/or
personal injury and possible death, for you
and for others.
iTire load rating5 (page 314) and tire
speed rating6 (
page 314) are also referred
to as “service description”.

327 Operation
Tires and wheels
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 295).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 393) and
(
page 412).
Warning!G
Have the tightening torque checked after
changing a wheel. Wheels could become
loose if not tightened with a torque of
96 lb-ft (130 Nm).
Only use Genuine Mercedes-Benz wheel
bolts specified for your vehicle’s rims.

329 Operation
Winter driving
Block heater* (Canada only)
The engine is equipped with a block
heater.
The electrical cable may be installed at an
authorized Mercedes-Benz Center.
Snow chains
Snow chains should only be driven on
snow-covered roads at speeds not to
exceed 30 mph (50 km/h). Remove chains
as soon as possible when driving on roads
without snow.
Please observe the following guidelines
when using snow chains:

Use of snow chains is not permissible
with all wheel/tire combinations
(
page 438).

Use snow chains in pairs and on rear
wheels only. Follow the manufacturer’s
mounting instructions.

Only use snow chains that are ap-
proved by Mercedes-Benz. Any
authorized Mercedes-Benz Center will
be glad to advise you on this subject.

Use of snow chains may be prohibited
depending on location. Always check
local and state laws before installing
snow chains.

Do not use snow chains on the spare
wheel (
page 445).
Warning!G
If you use your spare tire when winter tires
are fitted on the other wheels, be aware that
the difference in tire characteristics may
very well impair turning stability and that
overall driving stability may be reduced.
Adapt your driving style accordingly.
Have the spare tire replaced with a winter
tire at the nearest authorized
Mercedes-Benz Center.!When driving with snow chains, always se-
lect the raised level of the level control system
Airmatic (
page 230). Other settings may result
in damage to your vehicle.
!Some tire sizes do not leave adequate clear-
ance for snow chains. To help avoid serious dam-
age to your vehicle or tires, make sure that the
use of snow chains is permissible as specified in
the “Technical data” section of this Operator’s
Manual, see “Rims and tires” (
page 438).
!If snow chains are mounted to the front
wheels, they may scrape against the body or axle
components. The tires or the vehicle could be
damaged as a result.
iWhen driving with snow chains, you may
wish to deactivate the ESP® (page 94) before
setting the vehicle in motion. This will improve
the vehicle’s traction.
iCLS 63 AMG:
Do not switch off the ESP® when driving in snow
or with snow chains mounted.

339 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.
Wipe with a cloth moistened in a luke-
warm solution.
The surface may temporarily change
color. If this is the case, wait for it to
dry.
!Fold the windshield wiper arms back onto
the windshield before turning the SmartKey in
the starter switch or pressing the KEYLESS-GO
start/stop button (vehicles with KEYLESS-GO*).
Hold on to the wiper when folding the wiper arm
back. If released, the force of the impact from
the tensioning spring could crack the windshield.
!To clean the window interior, do not use a
dry cloth, abrasives, solvents or cleaners con-
taining solvents. Do not touch the inside of the
front, rear or side windows with hard objects
such as an ice scraper or ring. Doing so may
damage the windows.!Only use acid-free cleaning materials. Acid
may cause corrosion or damage the clear coat.
!The vehicle should not be parked for an ex-
tended 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.
Non-approved wheel cleaners may also damage
the wheel paint if the car is not driven after
cleaning. 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 approved Tire
Care and Mercedes-Benz approved Wheel Care
products, take care not to spray them on the
brake disks.
Warning!G
Do not use cleaners or cockpit care sprays
containing solvents to clean the cockpit or
the steering wheel. Cleaners containing sol-
vents will make the surface porous and vehi-
cle occupants could suffer serious injuries
from plastic parts coming loose in the event
of air bag deployment.

341 Operation
Vehicle care
Leather upholstery
Please note that leather upholstery is a
natural product and is therefore subject to
a natural aging process. Leather uphol-
stery may also react to certain ambient in-
fluences such as high humidity or high
temperature by showing wrinkles for ex-
ample.
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.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-plat-
ed 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.!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 corrosion.
