Interchanging the wheels

WARNING

G

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.

Morocco MR7319 ANRT 2012/

11/07/2012

! On vehicles fitted with a tyre pressure

monitor, electronic components are loca-

ted in the wheel.

Tyre-fitting tools should not be applied in

the area of the valve, as this could damage

the electronic components.

Interchanging the front and rear wheels of

differing dimensions can render the general

operating permit invalid.

Observe the instructions and safety notes in

the "Changing a wheel" section (Y page 367).

Move the front wheels to the straight-

ahead position.

^XVehicles with manual transmission:

depress the clutch pedal fully and engage

first or reverse gear.

^XVehicles with automatic transmission:

shift the automatic transmission to posi-

tion P.

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 5,000 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

warning system or the tyre pressure monitor.

X

Switch off the engine.

Vehicles without KEYLESS-GO: remove

the key from the ignition lock.

^XVehicles with KEYLESS-GO start-func-

tion or KEYLESS-GO: open the driver's

door.

The on-board electronics now have status

0. This is the same as the key having been

removed.

^XVehicles with KEYLESS-GO start-func-

tion or KEYLESS-GO: remove the Start/

Stop button from the ignition lock

(Y page 157).

If included in the vehicle equipment,

remove the tyre-change tool kit from the

vehicle.

Safeguard the vehicle against rolling away

Direction of rotation

Tyres with a specified direction of rotation

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

of aquaplaning. These advantages can only be

gained if the tyres are fitted corresponding to

the direction of rotation.

An arrow on the sidewall of the tyre indicates

its correct direction of rotation.

i Apart from some country-specific var-

iants, vehicles are not equipped with tyre-

changing tools. Some tools for changing a

wheel are specific to the vehicle. For more

information on which tools are required to

perform a wheel change on your vehicle,

consult a qualified specialist workshop.

Storing wheels

Necessary tyre-changing tools may

include, for example:

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.

Securing the vehicle against rolling

away

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

vehicle:

R

to raise the vehicle, only use the vehicle-

specific jack that has been tested and

approved by Mercedes-Benz. If the jack is

used incorrectly, it could tip over while the

vehicle is raised.

If your vehicle is equipped with a wheel chock,

it can be found in the tyre-change tool kit

(Y page 339).

The folding wheel chock is an additional

securing measure to safeguard the vehicle

from rolling away, for example when changing

a wheel.

R

the jack is designed only to raise and hold

the vehicle for a short time while a wheel

is being changed. It is not permissible to

use it to perform maintenance work under

the vehicle.

R

avoid changing the wheel on uphill and

X

downhill 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.

Fold both plates upwards :.

Fold out lower plate ;.

Guide the lugs on the lower plate fully into

R

the openings in base plate =.

R

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. rubber mats.

R

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.

X

Place chocks or other suitable items under

the front and rear of the wheel that is diag-

onally opposite the wheel you wish to

change.

R

never place your hands or feet under the

raised vehicle.

do not lie under the vehicle.

do not start the engine when the vehicle is

raised.

the wheel you wish to change by about one

full turn. Do not unscrew the bolts com-

pletely.

Using both hands, carefully reach into two

wheel trim openings and remove the wheel

trim.

Vehicles with hub caps: the hub cap covers

the wheel bolts. Before you can unscrew the

wheel bolts, you must remove the hub cap.

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, the vehicle has covers fitted next to the

jacking points on the outer sills.

WARNING

G

Oiled or greased wheel bolts or damaged

wheel bolts/hub threads can cause the wheel

bolts to come loose. As a result, you could

X

Position jack A at jacking point ?.

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.

Observe the instructions and safety notes on

"Changing a wheel" (Y page 367).

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.

X

Make sure that the base of the jack is posi-

tioned vertically under the jacking point.
