Useful information

This Operator's Manual describes all

models and all standard and optional

equipment of your vehicle available at the

time of publication of the Operator's

Manual. Country-specific differences are

possible. Please note that your vehicle may

not be equipped with all features

described. This also applies to safety-

related systems and functions.

Read the information on qualified

specialist workshops: (Y page 24).

Important safety notes

WARNING

Replace rims or tires with the same

designation, manufacturer and type as shown

on the original part. For further information

contact an authorized Mercedes-Benz Center.

If incorrectly sized rims and tires are

mounted, the wheel brakes or suspension

components can be damaged. Also, the

operating clearance of the wheels and the

tires may no longer be correct.

WARNING

Worn, old tires can cause accidents. If the tire

tread is worn to minimum tread depth, 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

recommended by Mercedes-Benz, since

previous damage cannot always be

recognized on retreads. The operating safety

of the vehicle cannot be assured when such

tires are used.

WARNING

If you notice sudden significant vibrations or

unusual handling performance or if you

suspect that damage has occurred to the

vehicle, you should activate the hazard

warning lamps, gently reduce speed and

carefully head for an area that is located at a

safe distance from the road.

Check the tires and the underside of the

vehicle for damage. If the vehicle seems

unsafe, have the vehicle towed away to the

nearest Mercedes-Benz Center or tire dealer

to be repaired.

WARNING

Do not drive with a flat tire. A flat tire affects

the ability to steer or brake the vehicle. You

might lose control of the vehicle. Continued

driving with a flat tire or driving at high speed

with a flat tire will cause excessive heat build-

up and possibly a fire.

Warning

A flat tire severely impairs the driving,

steering and braking characteristics of the

vehicle. There is a risk of an accident.

do not drive with a flat tire. Immediately

replace the flat tire with your spare wheel, or

consult a qualified specialist workshop.

Consult an authorized Mercedes-Benz Center

if you require information on approved and

recommended tires and wheels for summer

and winter operation. Advice on purchasing

and caring for tires is also available there.

Accessories that are not approved for your

vehicle by Mercedes-Benz or are not being

used correctly can impair the operating

safety.

Before purchasing and using non-approved

accessories, visit a qualified specialist

workshop and ask about:

suitability

legal stipulations

factory recommendations

Important safety notes

Wheels and tires

Information on the dimensions and types of

wheels and tires for your vehicle can be found

in the "Wheel/tire combinations" section

(Y page 338).

Information on air pressure for the tires on

your vehicle can be found:

on the tire pressure label on the fuel filler

flap

in the "Tire pressure" section

Further information on wheels and tires

can be obtained at any qualified specialist

workshop.

Operation

Notes on driving

If the vehicle is heavily loaded, check the tire

pressures and correct them if necessary.

When parking your vehicle, make sure that

the tires do not get deformed by the curb or

other obstacles. If it is necessary to drive over

curbs, speed humps or similar elevations, try

to do so slowly and at an obtuse angle.

Otherwise, the tires, particularly the

sidewalls, may be damaged.

Regular checking of wheels and tires

WARNING

Regularly check the tires for damage.

Damaged tires can cause tire inflation

pressure loss. As a result, you could lose

control of your vehicle.

Worn, old tires can cause accidents. If the tire

tread is worn to minimum tread depth, or if

the tires have sustained damage, replace

them.

Regularly check the wheels and tires of

your vehicle for damage at least once a

month, as well as after driving off-road or

on rough roads. Damage includes bulges

and deformation on tires, cuts, punctures,

cracks or severe corrosion on wheels, for

example. Damaged wheels can cause a

loss of tire pressure.

Regularly check the tire tread depth and

the condition of the tread across the whole

width of the tire (Y page 313). In order to

inspect the inner side of the tire surface,

turn the steering wheel to full lock.

All wheels must have a valve cap to protect

the valve against dirt and moisture. Do not

install anything onto the valve other than

the standard valve cap or a valve cap

approved by Mercedes-Benz for your

vehicle.

Do not install anything onto the valve, such

as tire pressure monitoring systems.

You should regularly check the pressure of

all your tires including the spare wheel,

particularly prior to long trips. Adjust the

tire pressure as necessary (Y page 321).

The service life of tires depends, among other

things, on the following factors:

driving style

tire pressure

distance covered

Tire tread

WARNING

Although the applicable federal motor vehicle

safety laws consider a tire to be worn when

the treadwear indicators (TWI) become visible

at approximately á inches (1.6 mm), we

recommend that you do not allow your tires

to wear down to that level. As tread depth

approaches â inches (3 mm) the adhesion

properties on a wet road are sharply reduced.

Depending upon the weather and/or road

surface (conditions), the tire traction varies

widely.
