Flat tyre

Preparing the vehicle

Your vehicle may be equipped with:

MOExtended tyres (tyres with run-flat char-

acteristics) (Y page 276)

a TIREFIT kit

an emergency spare wheel (only for certain

countries)

You can find information on changing/fitting

wheels in the "Wheel change" section

(Y page 298).

Vehicle preparation is notnecessary on

vehicles with MOExtended tyres.

Vehicles with MOExtended tyres are not

equipped with a TIREFIT kit at the factory.

It is therefore recommended that you addi-

tionally equip your vehicle with a TIREFIT kit

if you fit tyres that do not feature run-flat

characteristics, e.g. winter tyres. A TIREFIT

kit can be obtained from a qualified spe-

cialist workshop.

Stop the vehicle as far away as possible

from traffic on solid, non-slippery and level

ground.

Switch on the hazard warning lamps.

Apply the electric parkingbrake manually

(Y page 145).

Bring the front wheels into the straight-

ahead position.

Vehicles with manual transmission:

engage first or reverse gear.

Vehicles with automatic transmission:

move the DIRECT SELECT lever to P.

Switch off the engine.

Remove the key from the ignition lock.

All occupants must get out of the vehicle.

Make sure that they are not endangered as

they do so.

Make sure that no one is near the danger

area whilst a wheel is being changed.Any-

one who is not directly assisting in the

wheel change should, for example, stand

behind the barrier.

Getout of the vehicle. Pay attention to traf-

fic conditions when doing so.

Close the driver's door.

Place the warning triangle (Y page 274) a

suitable distance away. Observe legal

requirements.

MOExtended tyres (tyres with run-flat

characteristics)

WARNING

When driving in emergency mode, the driving

characteristics deteriorate, e.g. when corner-

ing, accelerating quickly and when braking.

There is a riskofaccident.

Do not exceed the statedmaximum speed.

Avoid abrupt steering and driving manoeu-

vres, and driving overobstacles (kerbs, pot-

holes, off-road). This applies in particular to a

laden vehicle.

Stop driving in emergency mode if:

you hear banging noises.

the vehicle starts to shake.

you see smoke and smell rubber.

ESP

is intervening constantly.

there are tears in the sidewalls of the tyre.

After driving in emergency mode, have the

wheel rims checked at a qualified specialist

workshop with regard to their further use. The

faulty tyre must be replaced.

With MOExtended tyres (tyres with run-flat

characteristics), you can continue to drive

your vehicle even if there is a total loss of

pressure in one or more tyres.

MOExtended tyres may only be used in con-

junction with an activated tyre pressure loss

warning system.

The driving distance possible is 80 km when

the vehicle is partially laden, and 30 km when

the vehicle is fully laden.

276

Flat tyre

Breakdown assistance

In addition to the vehicle load, the driving dis-

tance possible depends upon:

speed

road condition

outside temperature

The driving distance possible in run-flat mode

may be reduced by extreme driving condi-

tions/manoeuvres, or it can be increased

through a moderate style of driving.

The maximum permissible distance which

can be driven in run-flat mode is counted from

the moment the tyre pressure loss warning

appears in the multifunction display.

You must not exceed a maximum speed of

80 km/h.

When replacing one or all tyres, make

sure that you only use tyres marked

MOExtended. Also ensure that they are of

the specified size for the vehicle.

Vehicles with MOExtended tyres are not

equipped with a TIREFIT kit at the factory.

It is therefore recommended that you addi-

tionally equip yourvehicle with a TIREFIT kit

if you fit tyres that do not feature run-flat

characteristics, e.g. winter tyres. A TIREFIT

kit is available, for example, from a qualified

specialist workshop.

TIREFIT kit

Using the TIREFIT kit

TIREFIT is a tyre sealant.

You can use TIREFIT to seal punctures of up

to 4 mm, particularly those in the tyre tread.

You can use TIREFIT at outside temperatures

down to Ò20 †.

WARNING

In the following situations, the tyre sealant is

unable to provide sufficientbreakdown assis-

tance, as it is unable to seal the tyre properly:

there are cuts or punctures in the tyre

larger than those mentioned above.

the wheel rim is damaged.

you have driven at very low tyre pressures

or on a flat tyre.

There is a risk of accident.

Do not drive any further. Contact a qualified

specialist workshop.

WARNING

The tyre sealant is harmfuland causes irrita-

tion. It must not come into contact with your

skin, eyes or clothing or be swallowed. Do not

inhale TIREFIT fumes. Keep tyre sealant away

from children. There is a risk of injury.

If you come into contact with the tyre sealant,

observe the following:

Rinse off the tyre sealant from your skin

immediately with water.

If the tyre sealant comes into contact with

your eyes, immediately rinse them thor-

oughly with clean water.

If tyre sealant is swallowed, immediately

rinse your mouth outthoroughly and drink

plenty of water. Do not induce vomiting,

and seek medical attention immediately.

Immediately change out of clothing which

has come into contact with tyre sealant.

If an allergic reaction occurs, seek medical

attention immediately.

Do not remove any foreign objects which

have penetrated the tyre, e.g.screws or

nails.

Remove the tyre sealant bottle, the accom-

panying "max. 80 km/h" sticker and the

tyre inflation compressor from the stowage

well underneath the luggage compartment

floor (Y page 275).

Affix part : of the sticker within the driv-

er's field of vision.

Affix part ; of the sticker near the valve

on the wheel with the defective tyre.

Remove fillerhose B and plug = from the

bottom section of the tyre inflation com-

pressor housing.

Slide the yellow filler hose connector into

the mounting on yellow cap A of tyre seal-

ant bottle : until the plug engages.

With the sealing rings in front, slide yellow

cap A of tyre sealant bottle : into the

mounting of tyre inflation compressor ;

until the cap and both hooks engage.

Remove the cap from valve C on the faulty

tyre.

Screw filler hose D onto valve.

Insert plug = into the socket of the ciga-

rette lighter (Y page 257) or into a 12 V

power socket in your vehicle (Y page 257).

Turn the key to position 1(Y page 127) in

the ignition lock.

Press on/offswitch ? on the tyre inflation

compressor to ON.

The tyre inflationcompressor is switched

on. The tyre is inflated.

First, tyre sealant is pumped into the tyre.

The pressure can briefly rise to approx-

imately 500 kPa (5 bar/73 psi).

Do not switch off the tyre inflation com-

pressor during this phase.

Let the tyre inflation compressor run for a

maximum of ten minutes. The tyre should

then have attained a pressure of at least

200 kPa (2.0 bar/29 psi).

Do not operate the tyre inflation com-

pressor for longer than ten minutes at a

time without a break. It may otherwise

overheat.

The tyre inflation compressor can be oper-

ated again once it has cooled down.

If a tyre pressure of 200kPa (2.0bar/29psi)

has not been achieved after a maximum of ten

minutes, see (Y page 279).

If a tyre pressure of 200 kPa (2.0 bar/

29 psi) has not been achieved after a maxi-

mum of ten minutes, see (Y page 279).

Breakdown assistance

If tyre sealant leaks out, allow it to dry. It

can then be removed like a layer of film.

If you get tyre sealant on yourclothing,

have it cleaned as soon as possible with

perchloroethylene.

Tyre pressure of 200 kPa (2.0 bar/

29 psi) not reached

If apressure of 200 kPa (2.0 bar/29 psi) has

not been achieved after ten minutes:

Switch off the tyre inflation compressor.

Unscrew the filler hose from the valve of

the faulty tyre.

Very slowly drive forwards or reverse

approximately 10 m.

Pump up the tyre again.

After a maximum of ten minutes, the tyre

pressure must be at least 200 kPa (2.0 bar/

29 psi).

WARNING

If the required tyre pressure is not reached

after the specified time, the tyre is too badly

damaged. The tyre sealant cannot repair the

tyre in this instance. Damaged tyres and a tyre

pressure that is too low can significantly

impair the vehicle's braking and driving char-

acteristics. There is a risk of accident.

Do not continue driving. Contact a qualified

specialist workshop.

Tyre pressure of 200 kPa (2.0 bar/

29 psi) is reached

Switch off the tyre inflation compressor.

Unscrew the filler hose from the valve of

the faulty tyre.

After use, excess tyre sealant may run out

of the filler hose.This could cause stains.

Therefore, place the filler hose in the plastic

bag that contained the TIREFIT kit.

Stow the tyre sealant bottle, the tyre infla-

tion compressor and the warning triangle.

Pull away immediately.

WARNING

Atyre temporarily sealed with tyre sealant

impairs the driving characteristics and is not

suitable for higher speeds.There is a risk of

accident.

You should therefore adapt your driving style

accordingly and drive carefully. Do not exceed

the specified maximum speed with a tyre that

has been repaired using tyre sealant.

The maximum speed for a tyre sealed with

tyre sealant is 80 km/h. The "max. 80 km/h"

sticker must be affixed to the instrumentclus-

ter within the driver's field of vision.

Stop after driving for approximately ten

minutes and checkthe tyre pressure with

the tyre inflation compressor.

The tyre pressure must now be at least

130 kPa (1.3 bar/19 psi).

WARNING

If the required tyre pressure is not reached

after driving for a short period, the tyre is too

badly damaged. The tyre sealant cannot

repair the tyre in this instance. Damaged tyres

and a tyre pressure that is too low can signif-

icantly impair the vehicle's braking and driv-

ing characteristics. There is a risk of accident.

Do not continue driving. Contact a qualified

specialist workshop.

In your vehicle, you will find a sticker with

the Mercedes-BenzService24h telephone

number, e.g. on the B-pillar on the driver's

side.

Correct the tyre pressure if it is still at least

130 kPa (1.3 bar/19 psi) (see the fuel filler

flap for values).

To increase the tyre pressure: switch on

the tyre inflation compressor.

sure gauge ;.

To remove the tyre sealant bottle from the

tyre inflation compressor,press together

the locking tabs on the yellow cap.

Pull the tyre sealant bottle out of the tyre

inflation compressor.

The filler hose stays on the tyre sealant

bottle.

Stow the tyre sealant bottle, the tyre infla-

tion compressorand the warning triangle.

Drive to the nearestspecialist qualified

workshop and have the tyre changed there.

Have the tyre sealant bottle and the filler

hose replaced as soon as possible at a

qualified specialist workshop.

Have the tyre sealant bottle replaced every

four years at a qualified specialist work-

shop.

Environmental note

Have the used tyre sealant bottle disposed of

professionally, e.g. at aqualified specialist

workshop.

Battery

Important safety notes

Special tools and expertknowledge are

required when working on the battery, e.g.

removal and fitting. Youshould therefore

have all work involving the battery carried out

at a qualified specialist workshop.

WARNING

Work carried out incorrectly on the battery

can, for example, lead to a short circuit and

damage your vehicle's electronic system. This

can disrupt driving safety systems such as

ABS (anti-lock braking system) or ESP

(Elec-

tronic Stability Program).

If ABS malfunctions, the wheels can lock

during braking. This limits the steerability

of the vehicle when braking and the braking

distance may increase. There is a risk of

accident.

If ESP

malfunctions, the vehicle will not be

stabilised if it starts to skid or a wheel starts

to spin. There is a risk of accident.

You should therefore have all work involving

the battery carried out at a qualified specialist

workshop.

WARNING

Comply with safety precautions and take pro-

tective measures when handling batteries.

Risk of explosion

Fire, naked flames and

smoking are prohibited

when handling the battery.

Avoid creating sparks.
