MOExtended tyres (tyres with run-flat

characteristics)

General notes

With MOExtended tyres (tyres with run-flat char-

acteristics), you can continue to drive your vehi-

cle even if there is a total loss of pressure in one

or more tyres. The affected tyre must not show

any clearly visible damage.

You can recognise MOExtended tyres by the

"MOExtended" marking that appears on the tyre

sidewall. You will find this marking next to the

tyre size designation, the load-bearing capacity

and the speed index.

MOExtended tyres may be used only in conjunc-

tion with an activated tyre pressure loss warning

system or tyre pressure monitor.

If a pressure loss warning message appears

in the multifunction display:

observe the instructions in the display mes-

sages (Y page 239)

check the tyre for damage

if driving on, observe the following notes

The driving distance possible in run-flat mode is

approximately 80 km when the vehicle is parti-

ally laden and approximately 30 km when the

vehicle is fully laden.

In addition to the vehicle load, the driving dis-

tance possible in run-flat mode depends on the:

vehicle speed

road condition

outside temperature

The driving distance possible in run-flat mode

may be reduced by extreme driving conditions/

manoeuvres, or it can be increased through a

moderate style of driving.

The driving distance possible in run-flat mode is

counted from the moment the tyre pressure loss

warning appears on the multifunction display.

You must not exceed a maximum speed of

80 km/h.

When replacing one or all tyres, observe the fol-

lowing specifications for your vehicle's tyres:

size

type and

the "MOExtended" marking

If a tyre has gone flat and cannot be replaced

with an MOExtended tyre, a standard tyre may

be used as a temporary measure. Make sure

that you use the proper size and type (summer

or winter tyre).

Vehicles with MOExtended tyres are not equip-

ped with a TIREFIT kit at the factory. It is there-

fore recommended that you additionally equip

your vehicle with a TIREFIT kit if you fit tyres that

do not feature run-flat characteristics, e.g. win-

ter tyres. A TIREFIT kit can be obtained from a

qualified specialist workshop.

Important safety notes

WARNING

When driving in emergency mode, the driving

characteristics deteriorate, e.g. when corner-

ing, accelerating quickly and when braking.

There is a risk of accident.

Do not exceed the stated maximum speed.

Avoid abrupt steering and driving manoeu-

vres, and driving over obstacles (kerbs, pot-

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

laden vehicle.

workshop with regard to their further use. The

faulty tyre must be replaced.

TIREFIT kit

Important safety notes

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 sufficient breakdown 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 an accident.

Do not drive any further. Contact a qualified

specialist workshop.

WARNING

The tyre sealant is harmful and 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 out thoroughly 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.

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 which contained the TIREFIT kit.

Environmental note

Have the used tyre sealant bottle disposed of

professionally, e.g. at a qualified specialist

workshop.

Do not operate the tyre inflation compres-

sor for longer than ten minutes at a time with-

out a break. It may otherwise overheat.

The tyre inflation compressor can be oper-

ated again once it has cooled down.

Comply with the manufacturer's safety instruc-

tions on the sticker on the tyre inflation com-

pressor.

Turn the key to position 1 in the ignition lock

(Y page 133).

Press on and off switch ? on the tyre inflation

compressor to ON.

The tyre inflation compressor is switched on.

The tyre is inflated.

First, tyre sealant is pumped into the tyre. The

pressure may briefly rise to approximately

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).

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

been attained after ten minutes, see "Tyre pres-

sure reached" (Y page 298).

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

not been attained after ten minutes, see "Tyre

pressure not reached" (Y page 297).

If tyre sealant leaks out, make sure you clean the

affected area as quickly as possible. It is pref-

erable to use clear water.

If you get tyre sealant on your clothing, have it

cleaned as soon as possible with perchloroethy-

lene.

Tyre pressure not reached

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

not been attained after ten minutes:

Switch off the tyre inflation compressor.

Unscrew the filler hose from the valve of the

faulty tyre.

Please note that tyre sealant may leak out

when unscrewing the filler hose.

Very slowly drive forwards or reverse approx-

imately 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 reached

WARNING

A tyre 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 permissible speed for a tyre

sealed with tyre sealant is 80 km/h. The upper

part of the TIREFIT sticker must be affixed to the

instrument cluster where it will be easily seen by

the driver.

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

been attained after ten minutes:

Switch off the tyre inflation compressor.

Unscrew the filler hose from the valve of the

faulty tyre.

Please note that tyre sealant may leak out

when unscrewing the filler hose.

Stow the tyre sealant bottle, the tyre inflation

compressor and the warning triangle.

Pull away immediately.

Stop after driving for approximately ten

minutes and check the 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-Benz Service24h 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 tyre pres-

sure table on the fuel filler flap for values.

To increase the tyre pressure: switch on

the tyre inflation compressor.

When the tyre pressure is correct, unscrew

the filler hose from the valve of the sealed

tyre.

Please note that tyre sealant may leak out

when unscrewing the filler hose.

Screw the valve cap onto the tyre valve of the

sealed tyre.

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.

Battery (vehicle)

Important safety notes

Work on the battery, e.g. removing or fitting,

requires specialist knowledge and the use of

special tools. Therefore, always have work on

the battery carried out at a qualified specialist

workshop.

WARNING

Work carried out incorrectly on the battery

can lead, for example, to a short circuit and

thus damage the vehicle electronics. This can

lead to function restrictions applying to

safety-relevant systems, e.g the lighting sys-

tem, the ABS (anti-lock braking system) or the

ESP

(Electronic Stability Program). The oper-

ating safety of your vehicle may be restricted.

You could lose control of the vehicle, for

example:

when braking

in the event of abrupt steering manoeuvres

and/or when the vehicle's speed is not

adapted to the road conditions

There is a risk of an accident.

In the event of a short circuit or a similar inci-

dent, contact a qualified specialist workshop

immediately. Do not drive any further. Always

have work on the battery carried out at a

qualified specialist workshop.

Further information about ABS (Y page 66) and

ESP

(Y page 69).

WARNING

Electrostatic build-up can lead to the creation

of sparks, which could ignite the highly explo-

sive gases of a battery. There is a risk of an

explosion.

Before handling the battery, touch the vehicle

body to remove any existing electrostatic

build-up.

The highly flammable gas mixture is created

while the battery is charging and when jump-

starting.

Always make sure that neither you nor the bat-

tery is electrostatically charged. Electrostatic

charge is created, for example:

by wearing synthetic-fibre clothing

by friction between clothing and the seat

if you pull or push the battery across carpet or

other synthetic materials

if you rub the battery with a cloth

WARNING

During the charging process, a battery produ-

ces hydrogen gas. If a short circuit occurs or

sparks are created, the hydrogen gas can

ignite. There is a risk of an explosion.

Make sure that the positive terminal of a

connected battery does not come into con-

tact with vehicle parts.

Never place metal objects or tools on a bat-

tery.

It is important that you observe the descri-

bed order of the battery terminals when

connecting and disconnecting a battery.

When jump-starting, make sure that the

battery poles with identical polarity are

connected.

It is particularly important to observe the

described order when connecting and dis-

connecting the jump leads.

Never connect or disconnect the battery

terminals while the engine is running.

WARNING

Battery acid is caustic. There is a risk of injury.

Avoid contact with the skin, eyes or clothing.

Do not breathe in any battery gases. Do not

lean over the battery. Keep the batteries out

of the reach of children. Immediately rinse off

battery acid thoroughly with plenty of clean

water and seek medical attention at once.

You should have all work involving the bat-

tery carried out at a qualified specialist work-

shop. In the exceptional case that it is neces-

sary for you to disconnect the battery your-

self, make sure that:

you switch off the engine and remove the

key. On vehicles with KEYLESS-GO, ensure

that the ignition is switched off. Check that

all the indicator lamps in the instrument

cluster are off. Otherwise, electronic com-

ponents, 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.

Otherwise, the vehicle's electronic system

may be damaged.

in vehicles with automatic transmission,

the transmission is locked in position P

after disconnecting the battery. The vehicle

is secured against rolling away. You can

then no longer move the vehicle.

The battery and the cover of the positive ter-

minal clamp must be fitted securely during

operation.

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 bat-

tery. Avoid creating sparks.

Battery acid is caustic. Avoid contact

with the skin, eyes or clothing.

Wear suitable protective clothing; in

particular, gloves, an apron and a

face mask.

Immediately rinse acid splashes off

with clean water. Consult a doctor if

necessary.

Wear eye protection.

Keep children at a safe distance.

Observe this Owner's Manual.

For safety reasons, Mercedes-Benz recom-

mends that you only use batteries which have

been tested and approved for your vehicle by

Mercedes-Benz. These batteries provide

increased impact protection to prevent vehicle

occupants from suffering acid burns should the

battery be damaged in the event of an accident.

In order for the battery to achieve the maximum

possible service life, it must always be suffi-

ciently charged.

Like other batteries, the vehicle battery may

discharge over time if you do not use the vehicle.

In such cases, have the battery disconnected at

a qualified specialist workshop. You can also

charge the battery with a charger recommended

by Mercedes-Benz. For more information,

please contact a qualified 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 consumers. The

300

vehicle will then use very little energy, thus con-

serving battery power.

If the power supply has been interrupted, e.g. if

the battery was discharged, you will have to:

set the clock using the multimedia system;

see the separate operating instructions.

reset the function for folding the exterior mir-

rors in/out automatically, by folding the mir-

rors out once (Y page 104)

Charging the battery

WARNING

During charging and jump-starting, explosive

gases can escape from the battery. There is a

risk of an explosion.

Particularly avoid fire, naked flames, creating

sparks and smoking. Ensure there is sufficient

ventilation while charging and jump-starting.

Do not lean over a battery.

WARNING

Battery acid is caustic. There is a risk of injury.

Avoid contact with the skin, eyes or clothing.

Do not breathe in any battery gases. Do not

lean over the battery. Keep the batteries out

of the reach of children. Immediately rinse off

battery acid thoroughly with plenty of clean

water and seek medical attention at once.

WARNING

A discharged battery can freeze at tempera-

tures below freezing point. When jump-start-

ing the vehicle or charging the battery, gases

can escape from the battery. There is a risk of

an explosion.

Allow the frozen battery to thaw out before

charging it or jump-starting.

Only use battery chargers with a maximum

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 301).

Open the bonnet.

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 301).

If the indicator/warning lamps do not light up in

the instrument cluster at low temperatures, it is

very likely that the discharged battery has fro-

zen. In this case, you may neither jump-start the

vehicle nor charge the battery. The service life of

a battery that has been thawed may be reduced.

The starting characteristics may be impaired,

especially at low temperatures. Have the

thawed battery checked at a qualified specialist

workshop.

Only charge the installed battery with a battery

charger which has been tested and approved by

Mercedes-Benz. A battery charger unit specially

adapted for Mercedes-Benz vehicles and tested

and approved by Mercedes-Benz is available as

an accessory. This device permits charging of

the battery while it is installed. Contact a

Mercedes-Benz Service Centre for information

and availability. Read the battery charger's

operating instructions before charging the bat-

tery.

Jump-starting

For the jump-starting procedure, use only the jump-starting connection point, consisting of a pos-

itive terminal and an earth point, in the engine compartment.

WARNING

Battery acid is caustic. There is a risk of injury.

Avoid contact with the skin, eyes or clothing. Do not breathe in any battery gases. Do not lean over

the battery. Keep the batteries out of the reach of children. Immediately rinse off battery acid

thoroughly with plenty of clean water and seek medical attention at once.

WARNING

A discharged battery can freeze at temperatures below freezing point. When jump-starting the

vehicle or charging the battery, gases can escape from the battery. There is a risk of an explosion.

Allow the frozen battery to thaw out before charging it or jump-starting.

Vehicles with a petrol engine: avoid repeated and lengthy starting attempts. Otherwise, the

non-combusted fuel may damage the catalytic converter.

If the indicator/warning lamps do not light up in the instrument cluster at low temperatures, it is very

likely that the discharged battery has frozen. In this case you may neither jump-start the vehicle nor

charge the battery. Let the battery thaw first. The service life of a battery that has been thawed may

be reduced. The starting characteristics may be impaired, especially at low temperatures. Have the

thawed battery checked at a qualified specialist workshop.

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 a jump-starting device.

Vehicles with a petrol engine: jump-start the vehicle only when the engine and exhaust system

are cold.

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

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

Only use jump leads that are not damaged and have a sufficient cross-section and insulated

terminal clamps.

Make sure that the two vehicles do not touch.

the middle, e.g. with a white cloth

(30 x 30 cm). This will make other road

users aware that a vehicle is being towed.

Only secure the tow cable to the towing

eyes or, if available, to the trailer tow hitch.

Observe the brake lamps of the towing

vehicle while driving. Always maintain a dis-

tance a distance so that the tow rope does

not sag.

Do not use steel cables or chains to tow

your vehicle. You could otherwise damage

the vehicle.

Do not use the towing eyes for recovery pur-

poses as this could damage the vehicle. If in

doubt, recover the vehicle with a crane.

Pull away smoothly when towing away or

tow-starting a vehicle. If the tractive power is

too high, the vehicles could be damaged.

You may tow the vehicle for a maximum of

50km. A towing speed of 50 km/h must not

be exceeded.

Towing away and tow-starting

Breakdown assistance

For towing distances over 50 km, the front

axle or the entire vehicle must be raised and

transported.

To tow vehicles with KEYLESS-GO, use the

key instead of the Start/Stop button. The

automatic transmission may otherwise

switch to position P when you open the driv-

er's or front-passenger door which could

damage the transmission.

Vehicles with automatic transmission must

not be tow-started. The transmission may

otherwise be damaged.

Observe the legal requirements for the relevant

countries when towing and tow-starting.

It is better to have the vehicle transported than

to have it towed.

If the vehicle can no longer be driven because of

an accident or breakdown, you have the follow-

ing options:

transporting the vehicle

As a rule, you should have the vehicle trans-

ported.

towing the vehicle with a tow rope or tow bar

Electrical fuses

Important safety notes

WARNING

If you manipulate, bridge or replace a faulty

fuse with a fuse of a higher amperage, the

electric cables could be overloaded. This may

result in a fire. There is a risk of an accident

and injury.

Always replace faulty fuses with specified new

fuses of the correct amperage.

Only use fuses that have been approved for

Mercedes-Benz vehicles and which have the

correct fuse rating for the system concerned.

Only use fuses marked with an "S". Compo-

nents or systems could otherwise be dam-

aged.

Make sure that no moisture can enter the

fuse box when the cover is open.

When closing the cover, make sure that it is

lying correctly on the fuse box. Moisture seep-

ing in or dirt could otherwise impair the oper-

ation of the fuses.

The fuses in your vehicle disconnect faulty cir-

cuits. If a fuse blows, all the components in the

circuit and their functions will fail.

Blown fuses must be replaced with fuses of the

same rating, which you can recognise by the

colour and fuse rating. The fuse ratings are listed

in the fuse allocation chart.

The fuse allocation chart is in the fuse box in the

front-passenger footwell (Y page 309).

If the newly inserted fuse also blows, have the

cause traced and rectified at a qualified special-

ist workshop, e.g. a Mercedes-Benz Service

Centre.

Before replacing a fuse

Secure the vehicle against rolling away

(Y page 155).

Switch off all electrical consumers.

Vehicles without KEYLESS-GO: remove the

key from the ignition lock.

Vehicles with KEYLESS-GO start-function

or KEYLESS-GO: open the driver's door.

The vehicle electronics now have status 0.

This is the same as the key having been

removed.

The fuses are located in various fuse boxes:

Fuse box in the engine compartment on the

left-hand side of the vehicle, when viewed in

the direction of travel

Fuse box in the front-passenger footwell

The fuse allocation chart is on the fuse box in the

front-passenger footwell (Y page 309).
