! After use, excess tyre sealant may run out
of the filler hose. This could caus estains.
Therefore, place the filler hose in the plastic
bag which contained the TIREFIT kit. H
Environmental note
Have the used tyre sealant bottle disposed of
professionally, e.g. at aqualified specialist
workshop.
If at yre pressure of 180 kPa (1.8 bar/26 psi)
has been attained after five minutes:
X Switch off the tyre inflation compressor.
X Unscrew the filler hose from the valve of
the faulty tyre.
X Stow the tyre sealant bottle, the tyre infla-
tion compresso rand the warning triangle.
X Pull away immediately.
X Stop after driving for approximatel yten
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). G
WARNING
If the required tyre pressure is not reached
after driving for ashort period, the tyre is too
badly damaged. The tyre sealant cannot
repair the tyre in this instance. Damage dtyres
and atyre pressure that is too low can signif-
icantly impair the vehicle's braking and driv-
ing characteristics. There is arisk of accident.
Do not continue driving. Contact aqualified
specialist workshop.
i In yourv
ehicle, you willf indasticker with
the Mercedes-Benz Service24h telephone
number, e.g. on the B-pillar on the driver's
side.
X Correct the tyre pressure if it is still at least
130 kPa (1.3 bar/19 psi). See the fuel filler
flap for values.
X To increase the tyre pressure: switch on
the tyre inflation compressor. X
To reduce the tyre pressure: depress
pressure release button Enext to pres-
sure gauge F.
X When the tyre pressure is correct, unscrew
the filler hose from the valve of the sealed
tyre.
X Screw the valve cap onto the tyre valve of
the sealed tyre.
X Pullt he tyre sealant bottle out of the tyre
inflation compressor.
The filler hose stays on the tyre sealant
bottle.
X Drive to the nearest qualified specialist
workshop and have the tyre changed there.
X Have the tyre sealant bottle replaced as
soon as possible at aqualified specialist
workshop.
X Have the tyre sealant bottle replaced every
four years at aqualified specialist work-
shop. Battery (vehicle)
Important safety notes
Work on the battery ,e.g. removing or fitting,
requires specialist knowledge and the use of
specia ltools. Therefore, alwaysh ave work on
the battery carrie dout at aqualified specialist
workshop. G
WARNING
Work carried out incorrectly on the battery
can lead, for example, to ashort circuit and
thus damage the vehicl eelectronics. This can Battery (vehicle)

lead to function restrictions applying to
safety-relevant systems, e.g the lighting sys-
tem ,the AB S(anti-loc kbraking system) or the
ESP ®
(Electronic Stability Program). The oper-
atin gsafet yofy our vehicle may be restricted.
You could lose control of the vehicle, for
example:
R when braking
R in the even tofabrupt steerin gmanoeuvres
and/or when the vehicle's speed is not
adapted to the road conditions
There is arisk of an accident.
In the even tofashortcircuit or asimilar inci-
dent ,contac taqualified specialist workshop
immediately. Do not drive any further. Always have work on the battery carried out at a
qualified specialist workshop.
Further information about AB S(Ypage 77)
and ESP ®
(Y page 83). G
WARNING
Electrostatic build-up can lead to the creation of sparks, which could ignit ethe highly explo-
sive gases of abattery. There is arisk of an
explosion.
Before handlin gthe battery, touc hthe vehicle
body to remove any existin gelectrostatic
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
battery is electrostatically charged. Electro-
static charge is created, for example:
R by wearing synthetic fibre clothing
R due to friction betwee nclothing and the
seat
R when you pull or push the battery across
carpe torother synthetic materials
R when you rub the battery with acloth G
WARNING
Durin gthe charging process, abattery produ-
ces hydroge ngas. If ashor tcircuit occurs or spark
sare created, the hydroge ngas can
ignite. There is arisk of an explosion.
R Make sure that the positive terminal of a
connected battery does not com eintoc on-
tac twith vehicle parts.
R Never place metal object sortools on abat-
tery.
R It is importan tthat you observe the descri-
bed order of the battery terminals when
connectin gand disconnecting abattery.
R When jump-starting, make sure that the
battery poles with identical polarit yare
connected.
R It is particularly importan ttoobserve the
described order when connectin gand dis-
connectin gthe jump leads.
R Never connec tordisconnect the battery
terminals while the engin eisrunning. G
WARNING
Batter yacid is caustic. There is arisk of injury.
Avoid contac twith 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 plent yofclean
water and seek medical attention at once. H
Environmental note Batteries contain pollutants.
It is illegal to dispose of them
with the household rubbish.
They must be collected sep-
arately and dispose dofinan
environmentally responsible
recyclin gsystem. Dispose of batteries in an
environmentally responsible
manner. Take discharged
batteries to
aqualified spe-
cialist workshop or to acol-
lection point for used batter-
ies.
! Have the battery checked regularly at a
qualified specialist workshop. 402
Battery (vehicle)Breakdown assistance

Observe the service intervals in the Service
Booklet or contact aqualified 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:
R 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 components, such as the
alternator, may be damaged.
R you first remove the negative terminal
clamp and then the positive terminal
clamp. Never swap the terminal clamps.
Otherwise, the vehicle's electronic sys-
tem may be damaged.
R 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.
Comply with safety precautions and take pro-
tective measures when handling batteries. WARNING
Fire, naked flames and smoking
are prohibited when handling the
battery. Avoid creating sparks.
Battery acid is caustic. Avoid con-
tact with the skin, eyes or clothing.
Wear suitablep rotective clothing,
in particularg loves, an apron and a
face mask.
Immediately rinse acid splashes
off with clean water. Consult adoc-
tor if necessary. Wear eye protection.
Keep children away.
Observe this Owner's Manual.
HYBRID vehicles: make sure that you read
the "HYBRID" Supplement included in the
vehicle literature. You could otherwise fail to
recognise dangers, e.g. due to high voltage.
For safety reasons, Mercedes-Benz recom-
mends that you only use batteries which have been tested and approved for your vehicle by
Mercedes-Benz.T hese batteries provide
increased impact protection to prevent vehi-
cle occupants from suffering acid burns
should the battery be damagedint he event of
an accident.
In order for the battery to achieve the maxi-
mum possibles ervice life, it must always be
sufficiently charged.
The vehicle battery, like other batteries, can
discharge over time if you do not use the
vehicle. In such cases, have the battery dis-
connected at aqualified specialist workshop.
You can also charge the battery with a
charger recommended by Mercedes-Benz.
For more information, pleasec ontactaquali-
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 aqualified specialist
workshop if you wish to leave your vehicle
parked up for along period of time.
i 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. Battery (vehicle)

WARNING
During the charging process, abattery produces hydrogen gas. If ashort circuit occurs or sparks
are created, the hydrogen gas can ignite. There is arisk of an explosion.
R Make sure that the positive terminal of aconnected battery does not come into contact with
vehicle parts.
R Never place metal objects or tools on abattery.

age the vehicle.
! Do not use the towing eye for recovery,
this could damage the vehicle. If in doubt,
recover the vehicle with acrane.
! Pull aways
