WARNING

If wheels and tyres 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 tyres with those

that fulfil the specifications of the original

part.

WARNING

A flat 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 a flat 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 vehi-

cle by Mercedes-Benz or are not being used cor-

rectly can impair operating safety.

Before purchasing and using non-approved

accessories, visit a qualified specialist work-

shop and enquire about:

suitability

legal stipulations

factory recommendations

Further information regarding wheels and tyres

can be found under "Wheel/tyre combinations"

(Y page 323).

You can ask for information regarding permitted

wheel/tyre combinations at a Mercedes-Benz

Service Centre.

Information on tyre pressures can be found:

in the tyre pressure table in the fuel filler flap

(Y page 154)

under "Tyre pressure" (Y page 313)

Modification work on the brake system and

wheels is not permitted. The use of spacers or

brake dust shields is not permitted. This inva-

lidates the general operating permit for the vehi-

cle.

Further information on wheels and tyres can

be obtained at any qualified specialist work-

shop.

Operation

Information on driving

Check the tyre pressure when the vehicle is

heavily laden and adjust prior to a trip.

While driving, pay attention to vibrations, noises

and unusual handling characteristics, e.g. pull-

ing to one side. This may indicate that the

wheels or tyres are damaged. If you suspect that

a tyre is defective, reduce your speed immedi-

ately. Stop the vehicle as soon as possible to

check the 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 tyres and wheels checked at a

qualified specialist workshop.

When parking your vehicle, make sure not to

squash the tyre. If you cannot avoid driving over

obstacles, e.g. kerbs, do so slowly and at an

obtuse angle only. You could otherwise damage

the wheel rims and tyres.

Regular checking of 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.

310

Operation

Wheels and tyres

Check the tyres regularly for signs of damage

and replace any damaged tyres immediately.

Check wheels and tyres for damage at least

once a month. Check wheels and tyres after

driving off-road or on rough roads. Damaged

wheels can cause a loss of tyre pressure. Pay

particular attention to damage such as:

cuts in the tyres

punctures

tears in the tyres

bulges on the tyres

deformation or severe corrosion on the

wheels

Regularly check the tyre tread depth and the

condition of the tread across the whole width of

the tyre (Y page 311). If necessary, turn the

front wheels to full lock to make it easier 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 any-

thing onto the valve other than the standard

valve cap or other valve caps specially approved

for your vehicle by Mercedes-Benz. Do not fit

any other valve caps or systems, e.g. tyre pres-

sure monitors.

Check the pressure of all tyres regularly as well

as prior to long trips. Adjust the tyre pressure as

necessary (Y page 313).

Observe the notes on the emergency spare

wheel (Y page 323).

The service life of a tyre depends on various fac-

tors, including the following:

Driving style

Tyre pressure

Mileage

Notes on the 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.

Selecting, fitting and replacing tyres

WARNING

Exceeding the stated tyre load-bearing capa-

city and the approved maximum speed could

lead to tyre damage or the tyre bursting. There

is a risk of accident.

Therefore, only use tyre types and sizes

approved for your vehicle model. Observe the

tyre load rating and speed rating required for

your vehicle.

Pay special attention to country-specific

requirements for tyre approval. These require-

ments may stipulate a specific tyre type for your

vehicle. Furthermore, the use of a specific tyre

type in certain regions and areas of operation

can be highly beneficial. You can find further

information regarding tyres at specialist tyre

retailers, at qualified specialist workshops or at

any Mercedes-Benz Service Centre.

Use only tyres and wheels of the same type

and make.

Exception: it is permissible to fit a different

type or make in the event of a flat tyre.

Observe here the "MOExtended tyres (tyres

with run-flat characteristics)" section

(Y page 295).

Fit only tyres of the correct size onto the

wheels.

Run in new tyres at moderate speeds for the

first 100 km. They reach their full perform-

ance only after this distance.

Operation

311

Wheels and tyres

Do not drive with tyres that have too little

tread depth. This significantly reduces trac-

tion on wet roads (aquaplaning).

Replace the tyres after six years at the latest,

regardless of wear.

Observe the notes on the emergency spare

wheel (Y page 323).

MOExtended tyres (tyres with run-flat

characteristics)

With MOExtended tyres (tyres with run-flat char-

acteristics), you can continue to drive your vehi-

cle even if there is a total loss of pressure in one

or more tyres.

MOExtended tyres may be used only in conjunc-

tion with an activated tyre pressure loss warning

system or with an activated tyre pressure mon-

itor and only on wheels specifically tested by

Mercedes-Benz.

Notes on driving with MOExtended tyres with a

flat tyre (Y page 295).

Vehicles with MOExtended tyres are not equip-

ped with a TIREFIT kit at the factory. It is there-

fore recommended that you additionally equip

your vehicle with a TIREFIT kit if you fit tyres that

do not feature run-flat characteristics, e.g. win-

ter tyres. A TIREFIT kit can be obtained from a

qualified 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 318).

Driving with summer tyres

At temperatures below +7 †, summer tyres lose

elasticity and therefore traction and braking

power. Change the tyres on your vehicle 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.

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.

M+S tyres

WARNING

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

4 mm are 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.

At temperatures below +7 †, use winter tyres or

all-season tyres. 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 provide

the best possible grip in wintry road conditions.

Only these tyres will allow driving safety sys-

tems such as ABS and ESP

to function opti-

mally in winter. These tyres have been devel-

oped specifically for driving in snow.

Use M+S tyres of the same make and tread on all

wheels to maintain safe handling characteris-

tics.

Always observe the maximum permissible

speed specified for the M+S tyres you have fit-

ted.

If you fit M+S tyres that have a lower maximum

permissible speed than that of the vehicle, affix

an appropriate warning label in the driver's field

of vision. This can be obtained at a qualified

specialist workshop.

Under these circumstances, you should also

restrict the maximum design speed of the vehi-

cle using the permanent limiter to the maximum

permissible speed for the M+S tyres

(Y page 166).

312

Winter operation

Wheels and tyres

When you have fitted the M+S tyres:

Check the tyre pressures (Y page 313).

Restart the tyre pressure loss warning system

(Y page 315).

Restart the tyre pressure monitor

(Y page 317).

Information about driving with an emergency

spare wheel (Y page 323).

Snow chains

WARNING

If snow chains are fitted to the rear wheels,

they may scrape against the vehicle body or

chassis components. This could cause dam-

age to the vehicle or the tyres. There is a risk

of an accident.

To avoid hazardous situations:

never fit snow chains on the rear wheels

always fit snow chains in pairs to the front

wheels.

Vehicles with steel wheels: if you fit snow

chains on steel wheels, you may damage the

hub caps. Remove the hub caps from the rel-

evant wheels before fitting the snow chains.

For safety reasons, Mercedes-Benz recom-

mends that you only use snow chains that have

been approved for Mercedes-Benz or that are of

an equivalent standard of quality. For more

information, please contact a qualified special-

ist workshop.

If you wish to fit snow chains, please bear the

following points in mind:

Snow chains cannot be fitted to all wheel/

tyre combinations. Permitted wheel/tyre

combinations (Y page 323).

Use snow chains only if the road surface is

completely snow-covered. Remove the snow

chains as soon as possible when you come to

a road that is not snow-covered.

Local regulations may restrict the use of snow

chains. Observe the appropriate regulations if

you wish to fit snow chains.

do not exceed the maximum permissible

speed of 50 km/h.

do not use Parking Pilot when snow chains are

fitted (Y page 180).

You may wish to deactivate ESP

when pulling

away with snow chains fitted (Y page 70). This

allows the wheels to spin in a controlled manner,

achieving increased propulsive force (cut).

Information about driving with an emergency

spare wheel (Y page 323).

Tyre pressure

Tyre pressure specifications

WARNING

Underinflated or overinflated tyres pose the

following risks:

the tyres may burst, especially as the load

and vehicle speed increase.

the tyres may wear excessively and/or

unevenly, which may greatly impair tyre

traction.

the driving characteristics, as well as steer-

ing and braking, may be greatly impaired.

There is a risk of an accident.

Observe the recommended tyre pressure and

check the tyre pressure of all the tyres includ-

ing the spare wheel:

at least every two weeks

when the load changes

before embarking on a longer journey

for changed operating conditions, e.g. off-

road driving

If necessary, correct the tyre pressure.

WARNING

If you fit unsuitable accessories onto tyre

valves, the tyre valves may be overloaded and

malfunction, which can cause tyre pressure

loss. Due to their design, retrofitted tyre pres-

sure monitors keep the tyre valve open. This

can also result in tyre pressure loss. There is a

risk of accident.

Only screw standard valve caps or valve caps

specifically provided by Mercedes-Benz for

your vehicle onto the tyre valve.

Tyre pressure

313

Wheels and tyres

WARNING

If the tyre pressure drops repeatedly, the

wheel, valve or tyre may be damaged. Tyre

pressure that is too low may result in a tyre

blow-out. There is a risk of accident.

Check the tyre for foreign objects.

Check whether the wheel is losing air or the

valve is leaking.

If you are unable to rectify the damage, con-

tact a qualified specialist workshop.

Environmental note

Check the tyre pressure regularly, at least

every 14 days.

The recommended tyre pressures for various

operating conditions can be found in the tyre

pressure table on the fuel filler flap

(Y page 154).

Operation with an emergency spare wheel:

information on operation with an emergency

spare wheel can be found in the general notes in

the "Emergency spare wheel" section

(Y page 324).

Operation with a trailer: the applicable value

for the rear axle is the maximum value stated in

the tyre pressure table inside the fuel filler flap.

Additionally, the tyre pressure table may also

state tyre pressures for different load condi-

tions. These are defined in the table as different

numbers of passengers and amounts of lug-

gage. The actual number of seats may vary; for

more information, please refer to the vehicle

documents.

If tyre sizes are not specified, the tyre pressures

stated on the tyre pressure table apply for all

tyres approved at the factory for this vehicle.

If a tyre size precedes a tyre pressure, the fol-

lowing tyre pressure information is valid only for

that tyre size.

Use a suitable pressure gauge to check the tyre

pressure. The outer appearance of a tyre does

not give any reliable indication of the tyre pres-

sure. On vehicles fitted with the electronic tyre

pressure monitor, you can also check the tyre

pressure using the on-board computer.

If possible, correct tyre pressures only when the

tyres are cold.

The tyres are cold:

if the vehicle has been parked with the tyres

out of direct sunlight for at least three hours

and

if the vehicle has been driven less than

1.6 km

Depending on the ambient temperature, the

vehicle speed and the load on the tyres, the tyre

temperature and thus the tyre pressure changes

by approximately 10 kPa (0.1 bar/1.5 psi) per

10 †. Take this into account when checking the

pressure of warm tyres. Correct the tyre pres-

sure only if it is too low for the current operating

condition.

Driving with a tyre pressure that is too high or

too low can:

shorten the service life of the tyres

cause increased tyre damage

have a negative effect on handling character-

istics and thus driving safety (e.g. aquaplan-

ing)

The tyre pressure values given for low loads are

minimum values that offer you good driving

comfort characteristics.

However, you can also use the values given for

higher loads. These are permissible and will not

adversely affect the running of the vehicle.

Tyre pressure loss warning system

General notes

While the vehicle is in motion, the tyre pressure

loss warning system monitors the set tyre pres-

sure using the rotational speed of the wheels.

This enables the system to detect significant

pressure loss in a tyre. If the rotational speed of

a wheel changes as a result of a loss of tire

pressure, a corresponding warning message will

appear in the multifunction display.

Information on the message display can be

found in the "Restarting the tyre pressure loss

warning system" section (Y page 315).

Important safety notes

The tyre pressure warning system does not warn

you of an incorrectly set tyre pressure. Observe

the notes on the recommended tyre pressure

(Y page 313).

The tyre pressure loss warning system does not

replace the need to regularly check the tyre

pressure. An even loss of pressure on several

tyres at the same time cannot be detected by

the tyre pressure loss warning system.

The tyre pressure loss warning system is not

able to warn you of a sudden loss of air, e.g. if the

tyre is penetrated by a foreign object. In the

event of a sudden loss of air, bring the vehicle to

a halt by braking carefully. Avoid abrupt steering

manoeuvres.

The function of the tyre pressure loss warning

system is limited or delayed if:

snow chains are fitted on your vehicle

road conditions are wintry

you are driving on a loose surface (e.g. sand or

gravel)

you adopt a very sporty driving style (corner-

ing at high speeds or driving with high rates of

acceleration)

you are towing a very heavy or large trailer

you are driving with a heavy load (in the vehi-

cle or on the roof)

Restarting the tyre pressure loss warn-

ing system

Restart the tyre pressure loss warning system if

you have:

changed the tyre pressure

changed the wheels or tyres

fitted new wheels or tyres

Before restarting, make sure that the tyre

pressures are set properly on all four tyres for

the respective operating conditions. The rec-

ommended tyre pressures can be found in the

tyre pressure table on the fuel filler flap.

The tyre pressure loss warning system can

only give reliable warnings if you have set the

correct tyre pressure. If an incorrect tyre

pressure is set, this incorrect value will be

monitored.

Observe the notes in the section on tyre pres-

sures (Y page 313).

Make sure that the key is in position 2 in the

ignition lock (Y page 133).

Tyre pressure monitor

General notes

If a tyre pressure monitor system is fitted, the

vehicle's wheels have sensors fitted that moni-

tor the tyre pressures in all four tyres. The tyre

pressure monitor warns you if the pressure

drops in one or more of the tyres. The tyre pres-

sure monitor functions only if the corresponding

sensors are fitted to all wheels.

Tyre pressure

315

Wheels and tyres

Information on tyre pressures is shown on the

multifunction display. After a few minutes of

driving, the current tyre pressure of each tyre is

shown in the

Serv.Serv. menu of the multifunction

display, see illustration (example).

For information on the message display, refer to

the "Checking the tyre pressure electronically"

section (Y page 316).

Important safety notes

It is the driver's responsibility to set the tyre

pressure to the recommended cold tyre pres-

sure suitable for the operating situation

(Y page 313). Note that the correct tyre pres-

sure for the current operating situation must

first be taught-in to the tyre pressure monitor. If

a substantial loss of pressure occurs, the warn-

ing threshold for the warning message is aligned

to the taught-in reference values. Restart the

tyre pressure monitor after adjusting to the cold

tyre pressure (Y page 317). The current pres-

sures are saved as new reference values. This

ensures that a warning message appears only if

the tyre pressure drops significantly.

The tyre pressure monitor does not warn you of

an incorrectly set tyre pressure. Observe the

notes on the recommended tyre pressure

(Y page 313).

The tyre pressure monitor is not able to warn

you of a sudden loss of pressure, e.g. if the tyre

is penetrated by a foreign object. In the event of

a sudden loss of air, bring the vehicle to a halt by

braking carefully. Avoid abrupt steering

manoeuvres.

The tyre pressure monitor has a yellow warning

lamp on the instrument cluster for indicating a

pressure loss or malfunction. Depending on how

the warning lamp flashes or lights up, a tyre

pressure that is too low or a malfunction in the

tyre pressure monitor is indicated:

If the warning lamp is lit continuously, the tyre

pressure on one or more tyres is significantly

too low. The tyre pressure monitor is not mal-

functioning.

If the warning lamp flashes for around a

minute and then remains lit constantly, the

tyre pressure monitor is malfunctioning.

In addition to the warning lamp, a message

appears on the multifunction display. Observe

the information on display messages

(Y page 239).

It may take up to ten minutes for a malfunction

of the tyre pressure monitor to be indicated. A

malfunction will be indicated by the tyre pres-

sure warning lamp flashing for approximately

one minute and then remaining lit. When the

fault has been rectified, the tyre pressure warn-

ing lamp goes out after you have driven for a few

minutes.

The tyre pressure values indicated by the on-

board computer may differ from those meas-

ured at a filling station using a pressure gauge.

The tyre pressures shown by the on-board com-

puter refer to those measured at sea level. At

high altitudes, the tyre pressure values indica-

ted by a pressure gauge are higher than those

shown by the on-board computer. In this case,

do not reduce the tyre pressures.

The operation of the tyre pressure monitor can

be affected by interference from radio transmit-

ting equipment (e.g. cordless headphones, two-

way radios) that may be being operated in or

near the vehicle.

Observe the instructions and safety notes in the

display messages in the "Tyres" section

(Y page 239).

If the position of the wheels on the vehicle is

changed, the tyre pressures may be displayed in

the wrong positions for a short time. After a few

minutes of driving, this is rectified and the tyre

pressures are displayed in the correct positions.

Restarting the tyre pressure monitor

When you restart the tyre pressure monitor, all

existing warning messages are deleted and the

warning lamps go out. The monitor uses the cur-

rently set tyre pressures as the reference values

for monitoring. In most cases, the tyre pressure

monitor will automatically detect the new refer-

ence values after you have changed the tyre

pressure. However, you can also set reference

values manually as described here. The tyre

pressure monitor then monitors the new tyre

pressure values.

Use the table on the inside of the fuel filler flap

to ensure that the tyre pressure is set cor-

rectly in all four tyres for the current operating

conditions.

Also observe the notes in the section on tyre

pressures (Y page 313).

Make sure that the key is in position 2 in the

ignition lock (Y page 133).

Changing a wheel

Flat tyre

You can find information on what to do in the

event of a flat tyre in the "Breakdown assis-

tance" section (Y page 294). Information on

driving with MOExtended tyres in the event of a

flat tyre can be found under "Breakdown assis-

tance" (Y page 295).

Vehicles with an emergency spare wheel: in

the event of a flat tyre, the emergency spare

wheel is fitted according to the description

under "Fitting a wheel" (Y page 319).

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.

On vehicles fitted with a tyre pressure mon-

itor, electronic components are located in the

wheel.

Tyre-fitting tools should not be applied in the

area of the valve, as this could damage the

electronic components.

Only have tyres changed at a qualified spe-

cialist workshop.

Interchanging the front and rear wheels of dif-

fering dimensions can render the general oper-

ating permit invalid.

Observe the instructions and safety notes in the

"Changing a wheel" section (Y page 318).

The wear patterns on the front and rear tyres

differ depending on the operating conditions.

Interchange the wheels before a clear wear pat-

tern has formed on the tyres. Front tyres typi-

cally wear more on the shoulders, while rear

tyres wear more in the centre.

On vehicles that have front and rear wheels of

the same size, you can interchange the wheels

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

degree of tyre wear. Ensure the direction of

rotation is maintained.

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 warn-

ing system or the tyre pressure monitor.

318

Changing a wheel

Wheels and tyres

Direction of rotation

Tyres with a specified direction of rotation have

additional benefits, e.g. if there is a risk of aqua-

planing. These advantages can only be gained if

the tyres are fitted corresponding to the direc-

tion of rotation.

An arrow on the sidewall of the tyre indicates its

correct direction of rotation.

Storing wheels

Store wheels in a cool, dry and preferably dark

place if they are not being used. Protect the

tyres against oil, grease, petrol and diesel.

Fitting a wheel

Preparing the vehicle

Stop the vehicle on solid, non-slippery and

level ground.

Apply the electric parking brake manually.

Move the front wheels to the straight-ahead

position.

or KEYLESS-GO: remove the Start/Stop but-

ton from the ignition lock (Y page 133).

If included in the vehicle equipment, remove

the tyre-change tool kit from the vehicle.

In addition, safeguard the vehicle against roll-

ing away (Y page 155).

Apart from some country-specific variants,

vehicles are not equipped with a tyre-change

tool kit. Some tools for changing a tyre are

specific to the vehicle. For more information

on which tools are required to perform a

wheel change on your vehicle, consult a quali-

fied specialist workshop.

Necessary tyre-changing tools may include,

for example:

Jack

Wheel chock

Wheel wrench

Securing the vehicle against rolling

away

If your vehicle is equipped with a wheel chock, it

can be found in the tyre-change tool kit

(Y page 294).

The folding wheel chock is an additional secur-

ing measure to secure the vehicle against rolling

away, e.g. when changing a wheel.

Fold both plates upwards :.

Fold out lower plate ;.

Insert the lugs on the lower plate fully into the

openings in base plate =.

Place chocks or other suitable items under

the front and rear of the wheel that is diago-

nally opposite the wheel you wish to change.

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.

Observe the following when raising the vehi-

cle:

only use the vehicle-specific jack that has

been tested and approved by Mercedes-Benz

to raise the vehicle. If the jack is used incor-

rectly, it could tip over while the vehicle is

raised.

the jack is designed only to raise the vehicle

for a short time while a wheel is being

changed. It is not permissible to use it to per-

form maintenance work under the vehicle.

avoid changing the wheel on uphill and down-

hill slopes.

before raising the vehicle, safeguard it from

rolling away by applying the parking brake and

positioning wheel chocks. Do not release 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,

flat load-bearing underlay must be used. On a

slippery surface, a non-slip underlay must be

used, e.g. use a rubber mat on tiles.

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 that the distance between the

underside of the tyres and the ground does

not exceed 3 cm.

never place your hands or feet under the

raised vehicle.

do not lie under the raised vehicle.

do not start the engine when the vehicle is

raised.

do not open or close a door or the boot lid

when the vehicle is raised.

make sure that no persons are present in the

vehicle when raising the vehicle.

Vehicles with steel wheels: the hub cap cov-

ers the wheel bolts. Before you can unscrew the

wheel bolts, you must remove the wheel trim.

Using both hands, carefully reach into two

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 completely.

Jacking points

The jacking points are located just behind the

front wheel arches and just in front of the rear

wheel arches (arrows).

Mercedes-AMG vehicles and vehicles with

AMG equipment: to protect the vehicle body,

320

Changing a wheel

Wheels and tyres

the vehicle has covers fitted next to the jacking

points on the outer sills.

Covers, front (example: vehicles with AMG equip-

ment)

Mercedes-AMG vehicles and vehicles

with AMG equipment: fold cover ;

upwards.

Take ratchet ring spanner A out of the vehi-

cle tool kit and place it on the hexagon nut of

jack ? so that the letters AUF are visible.

Position jack ? at jacking point =.

Make sure that the base of the jack is posi-

tioned vertically under the jacking point.

Turn ratchet ring spanner A until jack ? sits

completely on jacking point = and the base

of the jack lies evenly on the ground.

Turn ratchet ring spanner A until the tyre is

raised a maximum of 3 cm from the ground.

Removing a wheel

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 a new 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 not continue 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.

It is imperative to observe the instructions and

safety notes on "Changing a wheel"

(Y page 318).

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.

Changing a wheel

321

Wheels and tyres

Clean the wheel and wheel hub contact sur-

faces.

Place the new wheel on the wheel hub and

push it on.

Tighten the wheel bolts until they are finger-

tight.

Lowering the vehicle

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.

Place the ratchet ring spanner onto the hex-

agon nut of the jack so that the letters AB are

visible.

Turn the ratchet ring spanner until the vehicle

is once again standing firmly on the ground.

Place the jack to one side.

Tighten the wheel bolts evenly in a crosswise

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.

Mercedes-AMG vehicles and vehicles

with AMG equipment: use the cover of the

outer sill.

Check the tyre pressure of the newly fitted

wheel and adjust if necessary.

Observe the recommended tyre pressure

(Y page 313).

If you are driving with the emergency spare

wheel fitted, the tyre pressure loss warning sys-

tem or the tyre pressure monitor cannot func-

tion reliably. Restart the tyre pressure loss warn-

ing system or tyre pressure monitor only once

the defective wheel has been replaced with a

new wheel.

Vehicles with tyre pressure monitor: all fitted

wheels must be equipped with functioning sen-

sors.

Wheels and tyres

Wheel and tyre combinations

General notes

You can ask for information regarding permitted

wheel/tyre combinations at a Mercedes-Benz

Service Centre.

You should regularly check the pressure of all

your tyres, including the emergency spare

wheel, particularly prior to long trips, and cor-

rect the pressure as necessary (Y page 313).

The value on the wheel is valid.

For safety reasons, Mercedes-Benz recom-

mends that you only use tyres and wheels

which have been approved by Mercedes-Benz

specifically for your vehicle.

These are specially adapted to the control

systems, such as ABS or ESP

and are

marked as follows:

MO = Mercedes-Benz Original

MOE = Mercedes-Benz Original Extended

(tyres featuring run-flat characteristics)

MO1 = Mercedes-Benz Original (only cer-

tain AMG tyres)

Mercedes-Benz Original Extended tyres may

only be used on wheels that have been spe-

cifically approved by Mercedes-Benz.

Only use tyres, wheels or accessories tested

and approved by Mercedes-Benz. Certain

characteristics, e.g. handling, vehicle noise

emissions or fuel consumption, may other-

wise be adversely affected. In addition, when

driving with a load, tyre dimension variations

could cause the tyres to come into contact

with the bodywork and axle components. This

could result in damage to the tyres or the

vehicle.

Mercedes-Benz accepts no liability for dam-

age resulting from the use of tyres, wheels or

accessories other than those tested and

approved.

Further information about wheels, tyres and

approved combinations can be obtained from

any qualified specialist workshop.

Retreaded tyres are neither tested nor rec-

ommended by Mercedes-Benz, since previ-

ous damage cannot always be detected on

retreaded tyres. As a result, Mercedes-Benz

cannot guarantee vehicle safety if retreaded

tyres are fitted. Do not fit used tyres if you

have no information about their previous

usage.

Large wheels: the lower the section width

for a certain wheel size, the lower the ride

comfort is on poor road surfaces. Roll comfort

and suspension comfort are reduced and the

risk of damage to the wheels and tyres as a

result of driving over obstacles increases.

The recommended tyre pressures for various

operating conditions can be found in the tyre

pressure table on the fuel filler flap. Further

information on tyre pressure (Y page 313).

Check tyre pressures regularly and only when

the tyres are cold.

Notes on the vehicle equipment – always fit the

vehicle:

with tyres of the same size across an axle

(left/right)

with the same type of tyre (summer tyres,

MOExtended tyres, winter tyres)

Exception: it is permissible to fit a different

type or make in the event of a flat tyre.

Observe the "MOExtended tyres (tyres with

run-flat characteristics)" section

(Y page 295).

Vehicles with MOExtended tyres are not equip-

ped with a TIREFIT kit at the factory. It is there-

fore recommended that you additionally equip

your vehicle with a TIREFIT kit if you fit tyres that

do not feature run-flat characteristics, e.g. win-

ter tyres. A TIREFIT kit can be obtained from a

qualified specialist workshop.

Emergency spare wheel

Important safety notes

WARNING

The wheel/tyre dimensions and the tyre type

of the spare wheel/emergency spare wheel

and the wheel to be replaced may differ. Fit-

ting a spare wheel/emergency spare wheel

may severely impair the driving characteris-

tics. There is a risk of accident.

To prevent hazardous situations:

Adapt your driving style accordingly and

drive carefully.

Never fit more than one spare wheel/emer-

gency spare wheel if the dimensions are

different to those of the wheel being

replaced.

Emergency spare wheel

323

Wheels and tyres

Only use a spare wheel/emergency spare

wheel briefly if the dimensions are different

to those of the wheel being replaced.

Do not switch off ESP

Have the spare wheel/emergency spare

wheel in question replaced at the nearest

qualified specialist workshop. Make sure

that the wheel/tyre dimensions and tyre

type are correct.

When using an emergency spare wheel or spare

wheel of a different size, you must not exceed

the vehicle's maximum design speed of

80 km/h.

You should regularly check the pressure of all

your tyres, including the emergency spare

wheel, particularly prior to long trips, and cor-

rect the pressure as necessary (Y page 313).

The value on the wheel is valid.

Snow chains must not be fitted to emergency

spare wheels.

General notes

You can ask for information regarding permitted

emergency spare wheels at a Mercedes-Benz

Service Centre.

An emergency spare wheel may also be fitted

against the direction of rotation. Observe the

time restriction on use as well as the speed lim-

itation specified on the emergency spare wheel.

Replace the tyres after six years at the latest,

regardless of wear. This also applies to the

emergency spare wheel.

If you are driving with the emergency spare

wheel fitted, the tyre pressure loss warning sys-

tem or the tyre pressure monitor cannot func-

tion reliably. Restart the tyre pressure loss warn-

ing system or tyre pressure monitor only once

the defective wheel has been replaced with a

new wheel.

Vehicles with tyre pressure monitor: after an

emergency spare wheel has been fitted, the sys-

tem may still display the tyre pressure of the

removed wheel for a few minutes. The value dis-

played for the position where the emergency

spare wheel is fitted is not the same as the cur-

rent tyre pressure of the emergency spare

wheel.

Removing the emergency spare wheel

Vehicles with the "Minispare" emergency spare

wheel:

The "Minispare" emergency spare wheel is

secured in emergency spare wheel bag : in the

boot.
