Useful information

This Operator's Manual describes all

models and all standard and optional equip-

ment 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 special-

ist workshops (Y page 28).

Important safety notes

WARNING

If wheels and tires of the wrong size are used,

the wheel brakes or suspension components

may be damaged. There is a risk of an acci-

dent.

Always replace wheels and tires with those

that fulfill the specifications of the original

part.

When replacing wheels, make sure to use the

correct:

designation

model

When replacing tires, make sure to use the

correct:

designation

manufacturer

model

WARNING

A flat tire severely impairs the driving, steer-

ing and braking characteristics of the vehicle.

There is a risk of accident.

Tires without run-flat characteristics:

do not drive with a flat tire.

immediately replace the flat tire with your

emergency spare wheel or spare wheel, or

consult a qualified specialist workshop.

Tires with run-flat characteristics:

pay attention to the information and warn-

ing notices on MOExtended tires (tires with

run-flat characteristics).

Accessories that are not approved for your

vehicle by Mercedes-Benz or that are not

being used correctly can impair operating

safety.

Before purchasing and using non-approved

accessories, visit a qualified specialist work-

shop and inquire about:

suitability

legal stipulations

factory recommendations

Information on dimensions and types of

wheels and tires for your vehicle can be found

(Y page 352).

Information on air pressure for the tires on

your vehicle can be found:

on the vehicle's Tire and Loading Informa-

tion placard on the B-pillar

on the tire pressure label on the fuel filler

flap (Y page 158)

under "Tire pressure" (Y page 328)

Further information on wheels and tires

can be obtained at any qualified specialist

workshop.

Operation

Information on driving

If the vehicle is heavily loaded, check the

tire pressures and correct them if neces-

sary.

While driving, pay attention to vibrations,

noises and unusual handling characteris-

tics, e.g. pulling to one side. This may indi-

cate that the wheels or tires are damaged.

If you suspect that a tire is defective,

reduce your speed immediately. Stop the

vehicle as soon as possible to check the

wheels and tires for damage. Hidden tire

damage could also be causing the unusual

Wheels and tires

handling characteristics. If you find no

signs of damage, have the wheels and tires

checked at a qualified specialist workshop.

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 eleva-

tions, 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

Damaged tires can cause tire inflation pres-

sure loss. As a result, you could lose control of

your vehicle. There is a risk of accident.

Check the tires regularly for signs of damage

and replace any damaged tires immediately.

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. Damaged wheels can cause a loss of

tire pressure. Pay particular attention to dam-

age such as:

cuts in the tires

punctures

tears in the tires

bulges on tires

deformation or severe corrosion on wheels

Regularly check the tire tread depth and the

condition of the tread across the whole width

of the tire (Y page 325). If necessary, turn the

front wheels to full lock in order to inspect the

inner side of the tire surface.

All wheels must have a valve cap to protect

the valve against dirt and moisture. Do not

mount anything onto the valve other than the

standard valve cap or other valve caps

approved by Mercedes-Benz for your vehicle.

Do not use any other valve caps or systems,

e.g. tire pressure monitoring systems.

Regularly check the pressure of all the tires

particularly prior to long trips. Adjust the tire

pressure as necessary (Y page 328).

The service life of tires depends, among other

things, on the following factors:

Driving style

Tire pressure

Distance covered

Important safety notes on the tire

tread

WARNING

Insufficient tire tread will reduce tire traction.

The tire is no longer able to dissipate water.

This means that on wet road surfaces, the risk

of hydroplaning increases, in particular where

speed is not adapted to suit the driving con-

ditions. There is a risk of accident.

If the tire pressure is too high or too low, tires

may exhibit different levels of wear at differ-

ent locations on the tire tread. Thus, you

should regularly check the tread depth and

the condition of the tread across the entire

width of all tires.

Minimum tire tread depth for:

Summer tires: â in (3 mm)

M+S tires: ã in (4 mm)

For safety reasons, replace the tires before

the legally prescribed limit for the minimum

tire tread depth is reached.

Bar indicator : for tread wear is integrated

into the tire tread.

Operation

325

Wheels and tires

Treadwear indicators (TWI) are required by

law. Six indicators are positioned on the tire

tread. They are visible once the tread depth is

approximately á in (1.6 mm). If this is the

case, the tire is so worn that it must be

replaced.

Selecting, mounting and replacing

tires

Only mount tires and wheels of the same

type and make.

Exception: it is permissible to install a dif-

ferent type or make in the event of a flat

tire. Observe the "MOExtended tires (tires

with run-flat characteristics" section

(Y page 307).

Only mount tires of the correct size onto

the wheels.

After mounting new tires, break them in at

moderate speeds for the first 60 miles

(100 km), as they only reach their full per-

formance after this distance.

Do not drive with tires which have too little

tread depth, as this significantly reduces

the traction on wet roads (hydroplaning).

Replace the tires after six years at the lat-

est, regardless of wear.

MOExtended tires (tires with run-flat

properties)

With MOExtended tires (tires with run flat

characteristics), you can continue to drive

your vehicle even if there is a total loss of

pressure in one or more tires.

MOExtended tires may only be used in con-

junction with an active tire pressure loss

warning system or with an active tire pressure

monitor and on wheels specifically tested by

Mercedes-Benz.

Notes on driving with MOExtended tires with

a flat tire (Y page 307).

Vehicles equipped with MOExtended tires

are not equipped with a TIREFIT kit at the

factory. It is therefore recommended that

you additionally equip your vehicle with a

TIREFIT kit if you mount tires that do not

feature run-flat properties, e.g. winter tires.

A TIREFIT kit can be obtained from a quali-

fied specialist workshop.

Winter operation

General notes

Have your vehicle winterproofed at a qualified

specialist workshop at the onset of winter.

Observe the notes in the "Changing a wheel"

section (Y page 348).

Driving with summer tires

At temperatures below 45 ‡(+7 †), summer

tires lose elasticity and therefore traction and

braking power. Change the tires on your vehi-

cle to M+S tires. Using summer tires at very

cold temperatures could cause cracks to

form, thereby damaging the tires perma-

nently. Mercedes-Benz cannot accept

responsibility for this type of damage.

WARNING

Damaged tires can cause tire inflation pres-

sure loss. As a result, you could lose control of

your vehicle. There is a risk of accident.

Check the tires regularly for signs of damage

and replace any damaged tires immediately.

M+S tires

WARNING

M+S tires with a tire tread depth of less than

ã in (4 mm) are not suitable for use in winter

and do not provide sufficient traction. There is

a risk of an accident.

M+S tires with a tread depth of less than ã in

(4 mm) must be replaced immediately.
