TIREFIT can be used in ambient tempera-
tures down to -4°F (-20°C).

Foreign objects (e.g. screws or nails)
should not be removed from the tire.

Take TIREFIT, the sticker, and the elec-
tric air pump out of the trunk.
!A wheel change should only be carried

Center. Otherwise there is a danger of
damaging the vehicle by jacking it up
incorrectly.
iOpen door only when conditions are
safe to do so.Warning!
G
Keep TIREFIT away from sparks, open flame
or heat source.
Do not smoke.
Warning!
G
TIREFIT is a limited repair device. TIREFIT
cannot be used for cuts or punctures larger
than approximately 0.16 in (4 mm) and tire
damage caused by driving with extremely
low tire inflation pressure, or on a flat tire, or
a damaged wheel.
Do not drive the vehicle under such circum-
stances.
Contact your nearest Mercedes-Benz
Center for assistance or call Roadside
Assistance. !After using TIREFIT, the tire inflation
pressure sensor may have to be re-
placed.


352 Practical hintsFlat tire
After attaining a tire inflation pressure
of 26 psi (1.8 bar), press0 on electric
air pump switch8.
The electric air pump should now be
switched off.

Turn the SmartKey in the ignition to
position0 (
page 40).

Detach the electric air pump.
The air hose may still be hot. Please ex-
ercise appropriate caution.

Store the electrical plug and the air
hose behind the flap and place the air
pump back in the trunk.

Close the trunk lid.

Drive away immediately.
The TIREFIT sealant will distribute itself
evenly inside the tire.

After driving vehicle for an initial
ten minutes, check tire inflation pres-
sure using the pressure gauge on the
air pump.
Warning!
G
If a tire inflation pressure of 26 psi (1.8 bar)
is not attained, tire is too severely damaged
for TIREFIT to provide a reliable tire repair.
In this case, TIREFIT cannot properly seal
the tire.
Do not drive the vehicle.
Contact the nearest Mercedes-Benz Center
or call Roadside Assistance.
Warning!
G
Do not exceed vehicle speed of
50 mph (80 km/h). A TIREFIT repair is not
designed to operate at higher speeds.
The sticker must be attached on the instru-
ment cluster where it will be easily seen by
the driver.
Vehicle handling characteristics may
change. Adapt your driving accordingly.
Warning!
G
If tire inflation pressure has fallen below
20 psi (1.3 bar) do not continue to drive the
vehicle.
Park your vehicle safely away from the road-
way and contact the nearest authorized
Mercedes-Benz Center or Roadside
Assistance.
If tire inflation pressure is at least
20 psi (1.3 bar), inflate tire to correct pres-
sure (see placards on driver’s door B-pillar
or on fuel filler flap), and drive vehicle to
nearest tire repair facility to have tire re-
paired or replaced.
Recommended duration of use:
300 miles (500 km) at 50 mph (80 km/h)

The battery for electrical consumers
(located in the trunk)Warning!
G
Failure to follow these instructions can re-
sult in severe injury or death.
Never lean over batteries while connecting,
you might get injured.
Observe all safety instructions and precau-
tions when handling automotive batteries
(page 250).
Battery fluid contains sulfuric acid. Do not
allow this fluid to come in contact with eyes,
skin or clothing. In case it does, immediately
flush affected area with water and seek
medical help if necessary.
A battery will also produce hydrogen gas,
which is flammable and explosive. Keep
flames or sparks away from battery, avoid
improper connection of jumper cables,
smoking, etc.!You must not jump start the vehicle,
otherwise the vehicle electrical sys-
tems could be damaged.
Only use the battery charge unit tested
and approved by Mercedes-Benz for
use on the SLR to charge the battery or
maintain the battery charge. Using oth-
er battery chargers may cause damage
to the vehicle and/or personal injury.
Information on charging the batteries
(page 355).

ies, notify an authorized
Mercedes-Benz Center.Warning!
G
Do not place metal objects on the battery as
this could result in a short circuit.
Use leak-proof batteries only to avoid the
risk of acid burns in the event of an
accident.

356 Practical hintsBatteriesCharging with the battery charger
Only use the battery charge unit approved
by Mercedes-Benz and supplied with your

matically control the charge rate, and
charge the battery or maintain the existing
charge in the battery while the vehicle is
parked and not being driven for long peri-
ods of time (on average approximately
three weeks or more). Not driving the vehi-
cle for such extended periods may cause
the charge in the vehicle battery to drop.
