Useful information

This Owner's Manual describes all models

and all standard and optional equipment

available to your vehicle at the time of pub-

lication of the Owner's Manual. Country-

specific deviations are possible. Please

note that your vehicle may not be equipped

with all features described. This also

applies to safety-relevantsystems and

functions.

Please read the information on qualified

specialist workshops (Y page 22).

Important safety notes

WARNING

If wheels and tyres of the wrong size are used,

the wheel brakes or suspensioncomponents

may be damaged. There is arisk of accident.

Always replace wheels and tyres with those

that fulfil the specifications of the original part

(designation, manufacturer, model).

WARNING

Aflat tyre severely impairs the driving, steer-

ing and braking characteristics of the vehicle.

There is a risk of accident.

Tyres without run-flat characteristics:

do not drive with aflat tyre.

immediately replace the flat tyre with your

emergency spare wheel or spare wheel, or

consult a qualified specialist workshop.

Tyres with run-flat characteristics:

pay attention to the information and warn-

ing notices on MOExtended tyres (tyres

with run-flat characteristics).

Accessories that are not approved for your

vehicle by Mercedes-Benzorare not being

used correctly can impair the operating

safety.

Before purchasing and using non-approved

accessories, visit a qualified specialist work-

shop and enquire about:

suitability

legal stipulations

factory recommendations

Information on the dimensions and types of

wheels and tyres for yourvehicle can be

found in the "Wheel/tyre combinations" sec-

tion (Y page 302).

Information on air pressure for the tyres on

your vehicle can be found:

on the tyre pressure label on the fuel filler

flap

in the "Tyre pressure" section

Modification work on the brake system and

wheels is not permitted. The use of wheel

spacers or brake dust shields is not permit-

ted. This invalidates the general operating

permit for the vehicle.

Further information on wheels and tyres

can be obtained at any qualified specialist

workshop.

Operation

Notes on driving

Check the tyre pressures when the vehicle

is heavily laden and, if necessary, adjust.

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 tyres are damaged.

If you suspect that a tyre is defective,

reduce your speed immediately. Stop the

vehicle as soon as possible to checkthe

wheels and tyres for damage. Hidden tyre

damage could also be causing the unusual

handling characteristics. If you find no

signs of damage, have the wheels and tyres

checked at a qualified specialist workshop.

When parking your vehicle, make sure that

the tyres do not get deformed by the kerb

or other obstacles. If it is necessary to drive

292

Operation

Wheels and tyres

over kerbs, speed humps or similar eleva-

tions, try to do so at an obtuse angle. Oth-

erwise, the tyres, particularly the sidewalls,

can get damaged.

Notes on regularly inspecting wheels

and tyres

WARNING

Damaged tyres can cause tyre inflation pres-

sure loss. As a result, you could lose control

of your vehicle. There is a risk of accident.

Check the tyres regularly for signs of damage

and replace any damaged tyres immediately.

Regularly check the wheels and tyres of

your vehicle for damage (e.g. cuts, punctu-

res, tears, bulges on tyres and deformation,

cracks or severe corrosion on wheels), at

least every 14 days, as well as after driving

off-road or on rough roads. Damaged

wheels can cause a loss of tyre pressure.

Regularly check the tyre tread depth and

the condition of the tread across the whole

width of the tyre (Y page 293). If neces-

sary, turn the front wheels to full lock in

order to inspect the inner side of the tyre

surface.

All wheels must have a valve cap to protect

the valve against dirt and moisture. Do not

fit anything onto the valve (such as tyre

pressure monitoring systems) other than

the standard valve cap or other valve caps

approved by Mercedes-Benz for your vehi-

cle.

You should therefore regularly check the

pressure of all your tyres, particularly prior

to long trips, and correctthe pressure as

necessary (Y page 295).

Observe the notes on the emergency spare

wheel (Y page 304).

The service life of tyres depends on various

factors, including the following:

driving style

tyre pressure

mileage

Tyre tread

WARNING

Insufficient tyre tread will reduce tyre trac-

tion. The tyre is no longer able to dissipate

water. This means that on wet road surfaces,

the risk of aquaplaning increases, in particular

where speed is not adapted to suit the driving

conditions. There is a risk of accident.

If the tyre pressure is too high or too low, tyres

may exhibit different levels of wear at differ-

ent locations on the tyre tread. Thus, you

should regularly check the tread depth and

the condition of the tread across the entire

width of all tyres.

Minimum tyre tread depth for:

summer tyres: 3 mm

M+S tyres: 4 mm

For safety reasons, replace the tyres before

the legally prescribed limit for the minimum

tyre tread depth is reached..

Notes on selecting, fitting and replac-

ing tyres

Only fit tyres and wheels of the same type

and make.

Only fit tyres of the correct size onto the

wheels.

After fittingnew tyres, run them in at mod-

erate speeds for the first 100 km, as they

only reach their full performance after this

distance.

Do not drive with tyres which have too little

tread depth, as this significantly reduces

the traction on wet roads (aquaplaning).

Replace the tyres after six years at the lat-

est, regardless of wear.

Wheels and tyres

Observe the notes on the emergency spare

wheel (Y page 304).

MOExtended tyres (tyres with run-flat

characteristics)

With MOExtended tyres (tyres with run-flat

characteristics), you can continue to drive

your vehicle even if there is a total loss of

pressure in one or more tyres.

MOExtended tyres may only be used in con-

junction with an activated tyre pressure loss

warning system and only on wheels specifi-

cally tested by Mercedes-Benz.

Notes on driving with MOExtended tyres in

the event of a flat tyre can be found in the

"Breakdown assistance" section

(Y page 276).

Vehicles with MOExtended tyres are not

equipped with a TIREFIT kit at the factory.

It is therefore recommended that you addi-

tionally equip your vehicle with the TIREFIT

kit if you fit tyres that do not feature run-

flat characteristics, e.g. winter tyres. A

TIREFIT kit can be obtained from a qualified

specialist workshop.

Winter operation

Points to remember

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 298).

Driving with summer tyres

At temperatures below +7 †, summer tyres

lose elasticity and therefore traction and

braking power; change the tyres on your vehi-

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

cold temperatures could cause tears to form,

thereby damaging the tyres permanently.

Mercedes-Benz cannot accept responsibility

for this type of damage.

M+S tyres

WARNING

M+S tyres with a tyre tread depth of less than

4mmare not suitable for use in winter as they

do not provide sufficient traction. There is a

risk of accident.

M+S tyres with a tread depth of less than

4 mm must be replaced.

When you have fitted the M+S tyres:

Check the tyre pressures (Y page 295).

Restart the tyre pressure loss warning sys-

tem (Y page 296).

At temperatures below +7 †, use winter tyres

or all-seasontyres.Both types of tyre are

identified by the M+S marking.

Only winter tyres bearing the i snowflake

symbol in addition to the M+S marking pro-

vide the best possible grip in wintry road con-

ditions. Only these tyres will allow driving

safety systems such as ABS and ESP

function optimally in winter, as these tyres

have been designed specifically for driving on

snow.

Use M+S tyres of the same make and tread

on all wheels to maintain safe handling char-

acteristics.

Always observe the maximum permissible

speed specified for the M+S tyres you have

fitted.

If you fit M+S tyres that have a lower maxi-

mum permissible speed than that of the vehi-

cle, affix an appropriate warning sign in the

driver's field of vision. This can be obtained in

a qualified specialist workshop.

Under these circumstances, you should also

restrict the maximum speed of the vehicle

using permanent SPEEDTRONIC so that it

does not exceed the maximum permissible

speed for the M+S tyres (Y page 154).
