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

approximately 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

R

Only mount tires and wheels of the same

type and make.

Exception: it is permissible to install a

different type or make in the event of a flat

tire. Observe the "MOExtended tires (tires

with run-flat characteristics" section

(Y page 354).

R

Only mount tires of the correct size onto

the wheels.

R

Break in new tires at moderate speeds for

the first 60 miles (100 km). They only reach

their full performance after this distance.

R

Do not drive with tires which have too little

tread depth, as this significantly reduces

the traction on wet roads (hydroplaning).

R

Replace the tires after six years at the

latest, regardless of wear.

Observe the notes on the emergency spare

wheel (Y page 410).

MOExtended tires (tires with run-flat

properties)

With MOExtended tires (tires with run flat

characteristics), you can continue to drive

your vehicle even if there is a total loss of

pressure in one or more tires.

MOExtended tires may only be used in

conjunction with an active tire pressure loss

warning system or with an active tire pressure

monitor and on wheels specifically tested by

Mercedes-Benz.

Notes on driving with MOExtended tires with

a flat tire (Y page 354).

i

Vehicles equipped with MOExtended tires

are not equipped with a TIREFIT kit at the

factory. It is therefore recommended that

you additionally equip your vehicle with a

TIREFIT kit if you mount tires that do not

feature run-flat properties, e.g. winter tires.

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 395).

Driving with summer tires

At temperatures below 45 ‡ (+7 †), summer

tires lose elasticity significantly, and

therefore traction and braking power as well.

Change the tires on your vehicle to

M+S tires. Using summer tires at very cold

temperatures could cause cracks to form,

thereby damaging the tires permanently.

Mercedes-Benz cannot accept responsibility

for this type of damage.

M+S tires

G

WARNING

M+S tires with a tire tread depth of less than

ã in (4 mm) are not suitable for use in winter

and do not provide sufficient traction. There

is a risk of an accident.

M+S tires with a tread depth of less than ã

in (4 mm) must be replaced immediately.

At temperatures below 45 ‡ (+7 †), use

winter tires or all-weather tires. Both types of

tire are identified by the M+S marking.
