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 it is necessary to drive over

curbs, speed humps or similar elevations, try

to do so slowly and at an obtuse angle.

Otherwise, the tires, particularly the

sidewalls, may be damaged.

Regular checking of wheels and tires

WARNING

Damaged tires can cause tire inflation

pressure 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.

Regularly check the wheels and tires of your

vehicle for damage at least once a month, as

well as after driving off-road or on rough

roads. Damaged wheels can cause a loss of

tire pressure. Pay particular attention to

damage such as:

R

cuts in the tires

R

punctures

R

tears in the tires

R

bulges on tires

R

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 373). 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

particularly prior to long trips. Adjust the tire

pressure as necessary (Y page 376).

Observe the notes on the emergency spare

wheel (Y page 410).

The service life of tires depends, among other

things, on the following factors:

R

driving style

R

tire pressure

R

distance covered

Important safety notes on the tire

tread

G

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

conditions. There is a risk of accident.

If the tire pressure is too high or too low, tires

may exhibit different levels of wear at

different 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:

R

Summer tires: â in (3 mm)

R

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.
