Make sure there are no vibrations, noises or

unusual handling characteristics when the vehicle

is in motion. This may indicate that the wheels or

tires are damaged. Hidden tire damage could also

be causing the unusual handling characteristics.

If you suspect that a tire is malfunctioning, reduce

your speed immediately and have the tires and

wheels checked at a qualied specialist workshop.

WARNINGARNING Risk of injury through damaged

tires

Damaged tires can cause tire pressure loss.

Check the tires regularly for signs of

damage and replace any damaged tires

immediately.

WARNINGARNING Risk of hydroplaning due to

insucient tire tread

Insucient tire tread will result in reduced tire

grip.

In heavy rain or slush the risk of hydroplaning

is increased, in particular where speed is not

adapted to suit the conditions.

Thus, you should regularly check the

tread depth and the condition of the

tread across the entire width of all tires.

Minimum tread depth for:

Summer tires: â in (3 mm)

M+S tires: ãin (4 mm)

For safety reasons, replace the tires

before the legally-prescribed limit for the

minimum tread depth is reached.

Carry out the following checks on all wheels regu-

larly, at least once a month or as required, for

example, prior to a long journey or driving o-

road:

Check the tire pressure (/ page 295).

Visually inspect wheels and tires for damage.

Check the valve caps.

Visual check of the tire tread depth and the

tire contact surface across the entire width.

The minimum tread depth for summer tires is

â in (3 mm) and for winter tires ã in (4 mm).

Six marks 1 show where the bar indicators

(arrow) are integrated into the tire tread. They are

visible once a tire tread depth of approximately

á in (1.6 mm) has been reached.

WARNINGARNING Risk of accident due to incor-

rectly installed snow chains

If you have installed snow chains to the rear

wheels, they may drag against the vehicle

body or chassis components.

Never install snow chains on the rear

wheels.

Only install snow chains on the front

wheels in pairs.

NOOTETE Damage to vehicle body or suspen-

sion components caused by installed

snow chains

On 4MATIC vehicles, if you install snow chains

on the rear wheels, you can damage vehicle

body or suspension components.

On 4MATIC vehicles, only install snow

chains on the front wheels.

NOOTETE Damage to the wheel trim from

mounted snow chains

If snow chains are mounted to steel wheels,

the wheel trims can be damaged.

Remove the wheel trims of steel wheels

before mounting snow chains.

Observe the following notes when using snow

chains:

Snow chains are only permissible for certain

wheel/tire combinations. You can obtain infor-

mation about this from an authorized

Mercedes-Benz Center.

For safety reasons, only use snow chains that

have been specically approved for your vehi-

cle by Mercedes-Benz, or snow chains with

the same quality standard.

If snow chains are installed, the maximum per-

missible speed is 30 mph (50 km/h).

Vehicles witehicles with Ah Activctive Pe Pararking Assistking Assist:: Do not

use Active Parking Assist when snow chains

are installed.

You can deactivate ESP

to pull away

(/ page 161). This allows the wheels to spin,

achieving an increased driving force.
