Ice and snow

Notes on regularly inspecting wheels and tyres

Close the lockable stowage spaces

before starting a journey.

Always stow and secure heavy, hard,

pointed, sharp-edged, fragile or bulky

objects in the boot.

WARNING Risk of injury due to damaged

tyres

Damaged tyres can cause tyre pressure loss.

Check the tyres regularly for signs of

damage and replace any damaged tyres

immediately.

Observe the notes on loading the vehicle.

WARNING Risk of aquaplaning due to

insuﬃcient tyre tread

Insuﬃcient tyre tread will result in reduced

tyre grip.

Turn the emergency key a quarter turn clock-

wise 2 (to lock) or anti-clockwise 1 (to

unlock).

The risk of aquaplaning is increased on wet

roads, especially when the speed of the vehi-

cle 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 tyres.

Quick start and Tips

Vehicles with Active Parking Assist: do not use

Active Parking Assist when snow chains are

ﬁtted.

Vehicles with level control: if snow chains are

above freezing point: e.g. MB SummerFit

below freezing point: e.g. MB WinterFit

For the correct mixing ratio, refer to the informa-

tion on the antifreeze container.

Mix washer ﬂuid with windscreen washer ﬂuid all

year round.

NOTE Damage to the exterior lighting due

to unsuitable windscreen washer ﬂuid

You can permanently limit the maximum

speed for driving with winter tyres

(/ page 349).

You can deactivate ESP^®to pull away

(/ page 340). This allows the wheels to spin,

achieving an increased driving force.

Unsuitable windscreen washer ﬂuids may

damage the plastic surface of the exterior

lighting.

Topping up the windscreen washer system

Only use windscreen washer ﬂuids which

are also suitable for use on plastic surfa-

ces, e.g. MB SummerFit or MB WinterFit.

DANGER Risk of fatal injuries when carry-

ing out maintenance work during the

charging process

Notes on windscreen washer ﬂuid

NOTE Blocked spray nozzles caused by

mixing windscreen washer ﬂuids

Observe the notes on operating ﬂuids

During the charging process, the high-voltage

on-board electrical system is under high volt-

age.

Do not mix MB SummerFit and MB Win-

terFit with other windscreen washer ﬂu-

ids.

WARNING ‑ Risk of ﬁre and injury due to

windscreen washer concentrate

Do not perform any maintenance work

during the charging process.

Windscreen washer concentrate is highly ﬂam-

mable. It could ignite if it comes into contact

with hot engine component parts or the

exhaust system.

Do not use distilled or de-ionised water. Other-

wise, the ﬁll level sensor may be triggered errone-

ously.

DANGER Risk of fatal injury due to poison-

ous exhaust gases

If the tailpipe is blocked or suﬃcient ventila-

tion is not possible, poisonous exhaust gases

such as carbon monoxide may enter the vehi-

cle. This is the case in enclosed spaces or if

the vehicle gets stuck in snow, for example.

The wiper arms will return to their original

positions.

Switch oﬀ the vehicle.

Check the condition of the wiper blades regu-

larly and replace them in the event of visible

damage or ongoing smearing.

Always switch the stationary heater oﬀ in

enclosed spaces without an air extrac-

tion system, e.g. in garages.

Service indicator

There is a service indicator at the tip of the newly

mounted wiper blade.

Keep the tailpipe and the area around

the vehicle free from snow when the

vehicle or the auxiliary heating is run-

ning.

Remove protective ﬁlm 1 from the service

indicator.

Open a door or a roof hatch on the wind-

ward side of the vehicle to ensure an

adequate supply of fresh air.

When the colour of the service indicator changes

from black to yellow, the wiper blades should be
