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 vehi-

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

rectly can impair the operating safety.

Before purchasing and using non-approved

accessories, visit a qualified specialist work-

shop and inquire about:

suitability

legal stipulations

factory recommendations

Further information regarding wheels and tires

can be found under "Wheel/tire combinations"

(Y page 279).

You can ask for information regarding permitted

wheel-tire combinations at an authorized

Mercedes-Benz Center.

Information on tire pressure can be found:

on the Tire and Loading Information placard

on the B-pillar on the driver's side

(Y page 266)

in the tire pressure table in the charge socket

flap (Y page 124)

under "Tire pressure" (Y page 260)

Operation

Information on driving

Check the tire 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 tires are damaged. If you suspect that

a tire is defective, reduce your speed immedi-

ately. Stop the vehicle as soon as possible to

check the wheels and tires for damage. Hidden

tire damage could also be causing the unusual

handling characteristics. If you find no signs of

damage, have the tires and wheels 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 they cannot be avoided, drive over

obstacles such as curbs slowly and at an obtuse

angle. Otherwise, you may damage the wheels

or tires.

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.

Wheels and tires

Check wheels and tires for damage at least once

a month. Check wheels and tires after driving

off-road or on rough roads. Damaged wheels

can cause a loss of tire pressure. Pay particular

attention to damage such as:

cuts in the tires

punctures in the tires

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 258). 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 par-

ticularly prior to long trips. Adjust the tire pres-

sure as necessary (Y page 260).

The service life of tires depends, among other

things, on the following factors:

Driving style

Tire pressure

Distance covered

Notes on 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.

Marking : shows where bar indicator ; for

tread wear is integrated into the tire tread.

Treadwear indicators (TWI) are required by law.

Six indicators are positioned on the tire tread.

They are visible once a tread depth of approx-

imately á in (1.6 mm) has been reached. If this

is the case, the tire is so worn that it must be

replaced.

Selecting, mounting and replacing

tires

WARNING

Exceeding the stated tire load-bearing capa-

city and the approved maximum speed could

lead to tire damage or the tire bursting. There

is a risk of accident.

Therefore, only use tire types and sizes

approved for your vehicle model. Observe the

tire load rating and speed rating required for

your vehicle.

Only mount tires and wheels of the same type

and make.

Exception: it is permissible to install a differ-

ent type or make in the event of a flat tire.
