Flat tyre

You can find information on whatto do in the

event of flat tyre in the "Flat tyre" section

(Y page 276). Instructions for driving with

MOExtended tyres in the event of a flat tyre

are also provided there.

Interchanging the wheels

WARNING

Interchanging the front and rear wheels may

severely impair the driving characteristics if

the wheels or tyres have different dimensions.

The wheel brakes or suspension components

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

dent.

Interchange front and rear wheels only if the

wheels and tyres are of the same dimensions.

Interchanging the front and rear wheels of

differing dimensions can render the general

operating permit invalid.

Always pay attention to the instructions and

safety warnings in the "Fitting a wheel" sec-

tion (Y page 298).

The wear patterns on the front and rear tyres

differ, depending on the operating conditions.

Interchange the wheels before a clear wear

pattern has formed on the tyres. Front tyres

typically wear more on the shoulders and the

rear tyres in the centre.

On vehicles that have the same size front and

rear wheels, you can interchange the wheels

every 5,000km to 10,000 km depending on

the degree of tyre wear. Maintain the direc-

tion of tyre rotation.

Clean the contact surfaces of the wheel and

the brake disc thoroughly every time a wheel

is interchanged. Check the tyre pressure and,

if necessary, restart the tyre pressure loss

warning system.

Direction of rotation

Tyres with a specified direction of rotation

have additional benefits, e.g. if there is a risk

of aquaplaning. You will only gain these ben-

efits if the correct direction of rotation is

observed.

An arrow on the sidewall of the tyre indicates

its correct direction of rotation.

Storing wheels

Store wheels that are not being used in a cool,

dry and preferably dark place. Protectthe

tyres against oil, grease, petrol and diesel.

Cleaning the wheels

WARNING

Do not use high-pressure cleaners with circu-

lar-jet nozzles (dirt grinders) to clean your

vehicle, in particular the tyres. You could oth-

erwise damage the tyres and cause an acci-

dent.

Fitting awheel

Preparing the vehicle

Park the vehicle on firm, non-slippery and

level ground.

Apply the electric parking brake manually

(Y page 145).

Bring the front wheels into the straight-

ahead position.

Vehicles with manual transmission:

engage first or reverse gear.

Vehicles with automatic transmission:

move the DIRECT SELECT lever to P.

Switch off the engine.

Remove the key from the ignition lock.

If a trailer is coupled to the vehicle, uncou-

ple it.

If included in the vehicle equipment, take

the tyre-change tool kit out of the vehicle.

Wheels and tyres

Secure the vehicle to prevent it from rolling

away.

Apart from some country-specific var-

iants, vehicles are not equipped with tyre-

changing tools. For more information on

which tools are required to performawheel

change on your vehicle, consult a

Mercedes-Benz Service Centre.

Required tyre-changing tools could be, for

example:

jack

wheel chock

wheel wrench

Securing the vehicle to prevent it from

rolling away

If your vehicle is equipped with a wheel chock,

it can be found in thevehicle tool kit

(Y page 275).

The folding wheel chockis an additional

securing measure to prevent the vehicle from

rolling away, for example when changing a

wheel.

Fold both plates upwards :.

Fold out lower plate ;.

Guide the lugs on the lower plate fully into

the openings in base plate =.

Securing the vehicle on level ground

On level ground: place wheel chocks or

other suitable items under the front and

rear of the wheel that is diagonally opposite

the wheel you wish to change.

Securing the vehicle on slight downhill gradients

On downhill gradients: place wheel

chocks or other suitable items in front of

the wheels of the front and rear axle.

Raising the vehicle

WARNING

If you do not position the jack correctly at the

appropriate jacking point of the vehicle, the

jack could tip over with the vehicle raised.

There is a risk of injury.

Only position the jack at the appropriate jack-

ing point of the vehicle. The base of the jack

must be positioned vertically, directly under

the jacking point of the vehicle.

Wheels and tyres

The following must be observed when raising

the vehicle:

to raise the vehicle, only use the vehicle-

specific jack that has been tested and

approved by Mercedes-Benz.Ifused incor-

rectly, the jack could tip over with the vehi-

cle raised.

the jack is designed only to raise and hold

the vehicle for a short time while a wheel

is being changed. It is not suited for per-

forming maintenance work under the vehi-

cle.

avoid changing the wheel on uphill and

downhill slopes.

before raising the vehicle, secure it from

rolling away by applying the parking brake

and inserting wheel chocks. Never disen-

gage the parking brake while the vehicle is

raised.

the jack must be placed on a firm, flat and

non-slip surface. On a loose surface, a

large, load-bearing underlay must be used.

On a slippery surface, a non-slip underlay

must be used, e.g. rubber mats.

do not use wooden blocks or similar

objects as a jack underlay.Otherwise, the

jack will not be able to achieve its load-

bearing capacity due to the restricted

height.

make sure thatthe distance between the

underside of the tyres and the ground does

not exceed 3 cm.

never place your hands and feet under the

raised vehicle.

never lie under the raised vehicle.

never start the engine when the vehicle is

raised.

never open or close a door or the tailgate

when the vehicle is raised.

make sure that no persons are present in

the vehicle when the vehicle is raised.

Steel wheel with wheel trim

Vehicles with steel wheels: carefully

reach into two of the wheel trim openings

and remove the wheel trim.

Using wheel wrench :, loosen the bolts on

the wheel you wish to change by about one

full turn. Do not unscrew the bolts com-

pletely.

The jacking points are located just behind the

front wheel arches and just in front of the rear

wheel arches (arrows).

Take the ratchet ring spanner out of the

tyre-changing tool kit and place it on the

hexagon nut of the jack so that the letters

AUF are visible.

Position jack = at jacking point ;.

Make sure that the base of the jack is posi-

tioned directly under the jacking point.

Turn ratchet ring spanner ? until jack =

sits completely on jacking point ; and the

base of the jack lies evenly on the ground.

Turn ratchet ring spanner ? until the tyre

is raised a maximum of 3 cm from the

ground.

Removing awheel

Do not place wheel bolts in sand or dirt.

The threads of the wheel bolts and wheel

hubs could otherwise be damaged when

the bolts are tightened.

Unscrew the wheel bolts.

Remove the wheel.

Fitting anew wheel

WARNING

Oiled or greased wheel bolts or damaged

wheel bolts/hub threads can cause the wheel

bolts to come loose.As a result, you could

lose a wheel while driving. There is a risk of

accident.

Never oil or grease wheel bolts. In the event

of damage to the threads, contact a qualified

specialist workshop immediately.Have the

damaged wheel bolts or hub threads

replaced/renewed. Do notcontinue driving.

WARNING

If you tighten the wheel bolts or wheel nuts

when the vehicle is raised, the jack could tip

over. There is a risk of injury.

Only tighten the wheel bolts or wheel nuts

when the vehicle is on the ground.

Always pay attention to the instructions and

safety notices in "Changing a wheel"

(Y page 298).

Only use wheel bolts that have been designed

for the wheel and the vehicle. For safety rea-

sons, Mercedes-Benz recommends that you

only use wheel bolts which have been

approved for Mercedes-Benz vehicles and the

respective wheel.

Clean the wheel and wheel hub contact

surfaces.

Place the new wheel on the wheel hub and

push it on.

Wheels and tyres

Tighten the wheel bolts until they are fin-

ger-tight.

Lowering the vehicle

Place the ratchet ring spanner onto the

hexagon nut of the jack so that the letters

AB are visible.

Turn the ratchet ring spanner until the vehi-

cle is once again standing firmly on the

ground.

Place the jack to one side.

WARNING

The wheels could work loose if the wheel nuts

and bolts are not tightened to the specified

tightening torque. There is a risk of accident.

Have the tightening torque immediately

checked at a qualified specialist workshop

after a wheel is changed.

Tighten the wheel bolts evenly in a cross-

wise pattern in the sequence indicated

(: to A). The tightening torque must be

130 Nm.

Turn the jack back to its initial position.

Stow the jack and the rest of the vehicle

tools in the vehicle again.

Check the tyre pressure of the newly fitted

wheel and adjust it if necessary.

Observe the recommended tyre pressure

(Y page 295).

Wheel and tyre combinations

Points to remember

For safety reasons, Mercedes-Benz rec-

ommends that you only use tyres and

wheels which have been approved by

Mercedes-Benz specifically for your vehi-

cle.

These are specially adapted to the control

systems, such as ABS or ESP

and are

marked as follows:

MO =Mercedes-BenzOriginal

MOE =Mercedes-BenzOriginal Extended

(tyres featuring run-flat characteristics)

MO1 =Mercedes-BenzOriginal (only cer-

tain AMG tyres)

Mercedes-Benz Original Extended tyres

may only be used on wheels that have been

specifically approved by Mercedes-Benz.

Only use tyres, wheels or accessories tes-

ted and approved by Mercedes-Benz. Cer-

tain characteristics, e.g. handling, vehicle

noise emissions or fuel consumption, may

otherwise be adversely affected. In addi-

tion, when driving with aload, tyre dimen-

sion variations could cause the tyres to

come into contact with the bodywork and

axle components.This could result in dam-

age to the tyres or the vehicle.

Mercedes-Benzaccepts no liability for

damage resulting from the use of tyres,

wheels or accessories otherthan those tes-

ted and approved.

Further information about wheels, tyres

and approved combinations can be

obtained from any qualified specialist

workshop.

Large wheels: the lower the section width

for a certain wheel size, the lower the ride

comfort is on poor road surfaces. Roll com-

fort and suspension comfort are reduced

and the risk of damage to the wheels and

tyres as a result of driving over obstacles

increases.
