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.

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).

Flat tyre

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.

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.

280

Battery

Breakdown assistance

Battery acid is caustic.

Avoid contact with the skin,

eyes or clothing.

Wearsuitable protective

clothing, in particular

gloves, an apronand a face

mask.

Immediately rinse acid

splashes off with clean

water. Consult a doctor if

necessary.

Wear eye protection.

Keep children away.

Observe this Owner's Man-

ual.

WARNING

For safety reasons, Mercedes-Benz recom-

mends thatyou only use batteries which have

been tested and approved for your vehicle by

Mercedes-Benz. These batteries provide

increased impact protection to prevent vehi-

cle occupants from suffering acid burns

should the battery be damaged in the event

of an accident.

To prevent acid burns, observe the following

safety notes when handling batteries:

do not lean over the battery.

do not place any metal objects on a battery.

Otherwise, you could cause a short circuit

and the battery's gas mixture could ignite.

make sure that you do not create an elec-

trostatic charge, e.g. by wearing synthetic

clothing or as a result of friction on fabrics.

Therefore, you should not pull or slide the

battery over carpets or other synthetic

materials.

never touch the battery first. To discharge

a possible electrostatic charge, step out of

the vehicle first and touch the bodywork.

do not wipe the battery using a cloth. The

battery may explode as a result of electro-

static charge or due to flying sparks.

Environmental note

Batteries contain pollutants.

It is illegal to dispose of them

with the household rubbish.

They must be collected sep-

arately and disposed of in an

environmentally responsible

recycling system.

Dispose of batteries in an

environmentally responsible

manner.Take discharged

batteries to a qualified spe-

cialistworkshop or to a col-

lection point for used batter-

ies.

Have the battery checked regularly at a

qualified specialist workshop.

Observe the service intervals in the Service

Booklet or contact a qualified specialist

workshop for more information.

You should have all work involving the

battery carried out at aqualified specialist

workshop. In the exceptional case that it is

necessary for you to disconnect the battery

yourself, make sure that:

you switch off the engine and remove the

key. On vehicles with KEYLESS-GO,

ensure that the ignition is switched off.

Checkthat all the indicator lamps in the

instrument cluster are off. Otherwise,

electronic components, such as the

alternator, may be damaged.

you first remove the negative terminal

clamp and then the positive terminal

clamp. Never swap the terminal clamps.

Battery

281

Breakdown assistance

Otherwise, the vehicle's electronic sys-

tem may be damaged.

in vehicles with automatic transmission,

the transmission is locked in position P

after disconnecting the battery. The vehi-

cle is secured against rolling away. You

can then no longer move the vehicle.

The battery and the cover of the positive

terminal clamp must be fitted securely dur-

ing operation.

In order for the battery to achieve the maxi-

mum possible service life, it must always be

sufficiently charged.

Like other batteries, the vehicle battery may

discharge over time if you do not use the

vehicle. In such cases, have the battery dis-

connected at a qualified specialist workshop.

You can also charge the battery with a

charger recommended by Mercedes-Benz.

For more information, please contact a quali-

fied specialist workshop.

Have the battery charge checked more fre-

quently if you use the vehicle mainly for short

trips or if you leave it standing idle for a

lengthy period. Consult a qualified specialist

workshop if you wish to leave your vehicle

parked up for a long period of time.

When you park the vehicle, remove the

key if you do not require any electrical con-

sumers. The vehicle will then use very little

energy, thus conserving battery power.

i If the power supply has been interrupted,

e.g. if the battery was discharged, you must

carry out the following tasks:

set the clock (audio system/COMAND

Online, see the separate operating

instructions).

reset the function for automatically fold-

ing the exterior mirrors in/out by folding

the mirrors out once (Y page 92).

Charging the battery

WARNING

Only charge the battery in a well-ventilated

area. As the battery is being charged, gases

can escape and generate minor explosions.

This could injure you and other persons or

cause damage to the paintwork or acid cor-

rosion on the vehicle.

You can obtain information on battery charg-

ers which allow the battery to be charged

while still installed from a qualified specialist

workshop.

WARNING

There is a risk of acid burns during the charg-

ing process due to the gases which escape

from the battery. Do not lean over the battery

during the charging process.

WARNING

Battery acid is caustic. Avoid contact with the

skin, eyes or clothing.

Only charge the installed battery with a

battery charger which has been tested and

approved by Mercedes-Benz.These battery

chargers allow the battery to be charged

while still installed in the vehicle.

Only use battery chargers with a maxi-

mum charging voltage of 14.8 V.

Only charge the battery using the jump-

start connection point.

The jump-starting connection point is in the

engine compartment (Y page 283).

Read the battery charger's operating instruc-

tions before charging the battery.

Open the bonnet (Y page 262).

Connect the battery charger to the positive

terminal and earth point in the same order

as when connecting the donor battery in

the jump-starting procedure

(Y page 283).

Jump-starting

WARNING

There is a risk of acid burns when jump-starting a vehicle due to the gases which escape from

the battery. Do not lean over the battery while the engine is being jump-started.

WARNING

Gases escaping from the battery during jump-starting may cause minor explosions. Avoid cre-

ating sparks. Keep naked flames away from the battery, and do not smoke.

Comply with safety precautions when handling batteries. You will find these under "Battery (vehi-

cle)" in the index.

WARNING

Non-combusted fuel can collect in the exhaust system and ignite. There is a risk of fire. Avoid

repeated and lengthy starting attempts.

Avoid repeated and lengthy starting attempts. Otherwise, the catalytic converter could be

damaged by the non-combusted fuel.

Do not use a rapid charging device to start the vehicle. If your vehicle's battery is discharged,

the engine can be jump-started from another vehicle or from a second battery using jump

leads. Observe the following points:

The battery is not accessible in all vehicles. If the other vehicle's battery is not accessible,

jump-start the vehicle using a second battery or ajump-starting device.

You may only jump-start the vehicle when the engine and catalyticconverter are cold.

Do not start the engine if the battery is frozen. Let the battery thaw first.

Jump-starting may only be performed from batteries with a nominal voltage of 12 V.

Only use jump leads that have a sufficient cross-section and insulated terminal clamps.

If the battery is fully discharged, leave the battery that is being used to jump-start connected

for a few minutes before attempting to start.This charges the empty battery a little.

Make sure that the two vehicles do not touch.

Make sure that:

the jump leads are not damaged.

bare parts of the terminal clamp do not come into contact with other metal parts while the

jump leads are connected to the battery.

the jump leads cannot come into contact with parts such as the V-belt pulley or the fan.
