TIREFIT kit
Important safety notes
TIREFIT is a tire sealant.
You can use TIREFIT to seal punctures of up to
0.16 in (4 mm), particularly those in the tire
tread. You can use TIREFIT at outside tempera-
tures down to Ò4 ‡ (Ò20 †).
GWARNING
In the following situations, the tire sealant is
unable to provide sufficient breakdown assis-
tance, as it is unable to seal the tire properly:
Rthere are cuts or punctures in the tire larger
than those mentioned above.
Rthe wheel rim is damaged.
Ryou have driven at very low tire pressures or on a flat tire.
There is a risk of an accident.
Do not drive the vehicle. Contact a qualified
specialist workshop.
GWARNING
The tire 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 tire sealant away
from children. There is a risk of injury.
If you come into contact with the tire sealant, observe the following:
RRinse off the tire sealant from your skin
immediately with water.
RIf the tire sealant comes into contact with
your eyes, immediately rinse them thor-
oughly with clean water.
RIf tire sealant is swallowed, immediately
rinse your mouth out thoroughly and drink
plenty of water. Do not induce vomiting,
and seek medical attention immediately.
RImmediately change out of clothing which
has come into contact with tire sealant.
RIf an allergic reaction occurs, seek medical
attention immediately.
!Do not operate the tire inflation compressor
for longer than ten minutes at a time without a break. It may otherwise overheat.
The tire inflation compressor can be operated
again once it has cooled down.
Comply with the manufacturer's safety instruc-
tions on the tire inflation compressor label and
on the tire sealant bottle.
Using the TIREFIT kit
XDo not remove any foreign objects which have
penetrated the tire, e.g. screws or nails.

The tire inflation compressor is switched on.
The tire is inflated.
First, tire sealant is pumped into the tire. The
pressure may briefly rise to approximately
500 kPa (5 bar/73 psi).
Do not switch off the tire inflation com-
pressor during this phase.
XLet the tire inflation compressor run for a
maximum of ten minutes. The tire should then
have attained a pressure of at least 180 kPa
(1.8 bar/26 psi).
If a pressure of 180 kPa (1.8 ba r/26 psi) has
been at tained after five minutes, see "Tire pres-
sure reached" (
Ypage 252).
If a tire pressure of 180 kPa (1.8 bar/26 psi) has
not been attained after five minutes, see "Tire
pressure not reached" (
Ypage 251).
If tire sealant has escaped, clean it off affected
areas as quickly as possible. It is preferable to
use clean water.
If your clothes ar e s
oiled with tire sealant, have
them cleaned with perchloroethylene at a dry
cleaner as soon as possible.
Tire pressure not reached
If a pressure of 180 kPa (1.8 bar/26 psi) has not
been attained after five minutes:
XSwitch off the tire inflation compressor.
XUnscrew the filler hose from the valve of the
faulty tire.
Tire sealant may escape when the filler hose is
unscrewed.
XVery slowly drive forwards or reverse approx- imately 30 ft (10 m).

GWARNING
If the required tire pressure is not reached
after the specified time, the tire is too badly
damaged. The tire sealant cannot repair the
tire in this instance. Damaged tires and a tire
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.
Tire pressure reached
GWARNING
A tire temporarily sealed with tire 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 tire that
has been repaired using tire sealant.
The maximum permissible speed for a tire
sealed with tire sealant is 50 mph (80 km/h).
The upper part of the TIREFIT sticker must be
affixed to the instrument cluster in the driver's
field of vision.
!Residue from the tire sealant may come out
of the filler hose after use. This could cause
stains.
Therefore, place the filler hose in the plastic
bag which contained the TIREFIT kit.
HEnvironmental note
Have the used tire sealant bottle disposed of
professionally, e.g. at a qualified specialist
workshop.
If a tire pressure of 180 kPa (1.8 bar/26 psi) has
been attained after five minutes:
XSwitch off the tire inflation compressor.
XUnscrew the filler hose from the valve of the
faulty tire.
Tire sealant may escape when the filler hose is
unscrewed.
XStow the tire sealant bottle and the tire infla-
tion compressor.
XPull away immediately.
XStop after driving for approximately ten
minutes and check the tire pressure with the
tire inflation compressor.
The tire pressure must now be at least
130 kPa (1.3 bar/19 psi).
GWARNING
If the required tire pressure is not reached
after driving for a short period, the tire is too
badly damaged. The tire sealant cannot repair
the tire in this instance. Damaged tires and a
tire 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.
iIn cases such as the one mentioned above,
contact an authorized Mercedes-Benz Cen-
ter. Or call 1-800-FOR-MERCedes (in the
USA) or 1-800-387-0100 (in Canada).
XCorrect the tire pressure if it is still at least
130 kPa (1.3 bar/19 psi). See the Tire and
Loading Information placard on the driver's
side B-pillar or the tire pressure table in the
fuel filler flap for values.
XTo increase the tire pressure: switch on the
tire inflation compressor.
XTo reduce the tire pressure: depress pres-
sure release button :next to pressure
gauge ;.
XWhen the tire pressure is correct, unscrew the
filler hose from the valve of the sealed tire.
Tire sealant may escape when the filler hose is
unscrewed.
XScrew the valve cap onto the tire valve of the
sealed tire.

Battery (vehicle)
Important safety notes
Special tools and expert knowledge are required
when working on the battery, e.g. removal and
installation. You should therefore have all work
involving the battery carried out at a qualified
specialist workshop.
GWARNING
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:
Rwhen braking
Rin the event of abrupt steering maneuvers
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. You
should have all work involving the battery car- ried out at a qualified specialist workshop.
For further information about ABS (
Ypage 58)
and ESP®(Ypage 62).
HEnvironmental note
Batteries contain dangerous
substances. It is against the
law to dispose of them with
the household rubbish. They
must be collected separately
and recycled to protect the
environment.
Dispose of batteries in an
environmentally friendly
manner. Take discharged
batteries to a qualified spe-
cialist workshop or a special
collection point for used bat-
teries.
!Have the battery regularly checked at a
qualified specialist workshop.
For more information, please contact a quali-
fied specialist workshop.
!Always have work on batteries carried out at
a qualified specialist workshop.
Should it, in exceptional circumstances, be
absolutely necessary to disconnect the 12-
volt battery yourself, please observe the fol-
lowing:
RSecure the vehicle to prevent it from rolling
away.
RSwitch off the ignition.
RDisconnect the negative terminal first and
then the positive terminal.
The transmission is locked in position j
after disconnecting the battery.
After the work has been done, install the bat-
tery and replace the cover of the positive ter-
minal clamp firmly.
Comply with safety precautions and take pro-
tective measures when handling batteries.
Risk of explosion.
Fire, open flames and smoking are
prohibited when handling the bat-
tery. Avoid creating sparks.
Battery (vehicle)253

The electrolyte of the battery is cor-
rosive. Avoid contact with skin, eyes
or clothing.
Wear suitable protective clothing,
especially gloves, apron and face-
guard.
Immediately rinse electrolyte
splashes off with clean water. Con-
tact a physician if necessary.
Wear eye protection.
Keep children away.
Observe this Operator'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 this case, have the battery disconnected at a
qualified specialist workshop. You can also
charge the battery with a special charger rec-
ommended by Mercedes-Benz. Contact a quali- fied specialist workshop for further information.
Have the battery condition of charge checked
more frequently 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 for a long period of time.
When you use the SmartKey in the ignition and
you park the car, remove the SmartKey if you do not require any electrical consumers. The vehi-
cle will then use very little energy, thus conserv-
ing battery power.
If the power supply has been interrupted, e.g. if
you reconnect the battery, you will have to:
Rreset the function for automatically folding
the exterior mirrors in/out by folding the mir-
rors out once (
Ypage 92)
Rreset the side windows, see (Ypage 78)
Charging the battery
!
Only use battery chargers with a maximum
charging voltage of 14.4 V.
!Only charge the battery using the jump-
starting connection point.
The jump-starting connection point is in the
engine compartment (
Ypage 254).
XOpen the hood.
XConnect the battery charger to the positive
terminal and ground point in the same order
as when connecting the donor battery in the
jump-starting procedure (
Ypage 254).
Keep away from fire and open flames. Do not
lean over a battery. Never charge the battery if it
is still installed in the vehicle, unless you use a
battery charger which has been tested and
approved by Mercedes-Benz. A battery charger
unit specially adapted for Mercedes-Benz vehi-
cles and tested and approved by Mercedes-
Benz is available as an accessory. It permits the
charging of the battery in its installed position.
Contact an authorized Mercedes-Benz Center
for further information and availability. Read the
battery charger's operating instructions before
charging the battery.
Do not charge a battery which has been
removed at low temperatures with a battery
charger. Allow the battery to warm up gently
first, if necessary. Otherwise, the service life can
be shortened and the starting characteristics
impaired, especially at low temperatures.
Jump-starting
XFor the jump-starting procedure, use only the jump-starting connection point in the engine com- partment, consisting of a positive terminal and a ground point.
