-if the reflective safety jackets are correctly
fastened
RBefore use, ensure that the reflective safety
jackets are clean and intact. The special prop-
erties may otherwise be compromised.
RThe reflective safety jackets should be stored
in their original packaging in a dry place away
from sources of heat and light.
RThe maximum number of washes specified is not the only factor influencing the life span of
the reflective safety jackets. Their life span
also depends on use, care, storage, etc.
RThe reflective safety jackets should be dis-
posed of and replaced with new ones:
-after 15 washes, and/or
-if the reflective strips have become
scratched, and/or
-if the backing material and/or reflective
strips have become soiled and cannot be
cleaned off, and/or

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 200 kPa
(2.0 bar/29 psi).
If a pressure of 200 kPa (2.0 bar/29 psi) has
been attained after five minutes, see "Tire pres-
sure reached" (
Ypage 324).
If a tire pressure of 200 kPa (2.0 bar/29 psi) has
not been attained after five minutes, see "Tire

If your clothes are soiled with tire sealant, have
them cleaned with perchloroethylene at a dry
cleaner as soon as possible.
Tire pressure not reached
If a tire pressure of 200 kPa (2.0 bar/29 psi) has
not been attained after ten 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).
XPump up the tire again.
After a maximum of ten minutes, the tire pres-
sure must be at least 200 kPa (2.0 bar/
29 psi).
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. If a tire pressure of 200 kPa (2.0 bar/29 psi) has
been attained after ten 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.
In cases such as the one mentioned above, con- tact an authorized Mercedes-Benz Center. 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 B-pillar on
the driver's side or the tire pressure table in
the fuel filler flap for values.
XTo increase the tire pressure: switch on the
tire inflation compressor.

Battery (vehicle)
12 V battery – 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 and ESP
®,
see (Ypage 65) and (Ypage 70).

ion battery:
GWARNING
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 forms when
charging the battery as well as when jump-start-
ing.
Always make sure that neither you nor the bat-
tery is electrostatically charged. A build-up of
electrostatic charge can be caused, for exam-
ple:
Rby wearing clothing made from synthetic
fibers
Rdue to friction between clothing and seats
Rif you push or pull the battery across the car-
pet or other synthetic materials
Rif you rub the battery with a cloth
GWARNING
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.
RMake sure that the positive terminal of a
connected battery does not come into con- tact with vehicle parts.
RNever place metal objects or tools on a bat-
tery.
RIt is important that you observe the descri-
bed order of the battery terminals when
connecting and disconnecting a battery.
RWhen jump-starting, make sure that the
battery poles with identical polarity are
connected.
