Environmental note
Have the used tyre sealant bottle disposed of professionally, e.g. at a qualified specialist
workshop.
If a tyre pressure of 180 kPa (1.8 bar/26 psi) has been achieved after ten 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 compressor and the warning triangle.
X Pull away immediately .
The maximum 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.
X 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). G
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.
i 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.
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 :next to pres-
sure gauge ;.
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 Pull the tyre sealant bottle out of the tyre
inflation compressor.
The filler hose stays on the tyre sealant
bottle.
X Stow the tyre sealant bottle, the tyre infla-
tion compressor and the warning triangle.
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 a qualified specialist
workshop.
X Have the tyre sealant bottle replaced every
four years at a qualified specialist work-
shop. 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. 582
Battery (vehicle)Breakdown assistance

!
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 a qualified 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 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.
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 suitable protective clothing,
in particular gloves, an apron and a
face mask.
Immediately rinse acid splashes
off with clean water. Consult a doc- tor if necessary. Wear eye protection.
Keep children away.
Observe this Owner's Manual.
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 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.
i When you park the vehicle, remove the
key if you do not require any electrical con- sumers. The vehicle will then use very littleenergy, thus conserving battery power. Charging the battery

WARNING
During charging and jump-starting, explosive
gases can escape from the battery. There is a risk of an explosion.
