2009 MERCEDES-BENZ SLR inflation pressure

368 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 starter switch
to position0 (
page 40).

Detach the electric air pump.
The air hose may still be hot. Please
exercise appropriate caution.

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

Close the trunk lid.

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

After driving vehicle for an initial
10 minutes, check tire inflation pres-
sure using the pressure gauge on the
air pump.

If tire inflation pressure is at least
20 psi (1.3 bar), inflate tire to correct
pressure (see placard on driver’s door
B-pillar) and contact a nearest qualified
workshop, e.g. an authorized
Mercedes-Benz Center, to have the
damaged tire replaced.
Recommended duration of use:
A maximum of 300 miles (500 km) at
or below 50 mph (80 km/h) with the
recommended tire inflation pressure.
Warning!
G
If a tire inflation pressure of 26 psi (1.8 bar)
is not attained, the 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.
Have the damaged tire replaced.


369 Practical hints
Flat tire

Contact an authorized Mercedes-Benz
Center as soon as possible to obtain a
new TIREFIT kit.

Bring used TIREFIT materials to an
authorized Mercedes-Benz Center for
proper disposal.

Replace your TIREFIT container every
4 years. Replacement containers are
available at your authorized
Mercedes-Benz Center.
Warning!
G
Have worn or damaged tires replaced in
pairs (front pair or rear pair) an make sure
the tires rotate in the direction specified
(page 262). Otherwise, the driving stabili-
ty of the vehicle will be adversely affected,
especially when driving at high speeds.
Warning!
G
Follow recommend tire inflation pressures.
Do not underinflate tires. Underinflated tires
wear excessively and/or unevenly,
adversely affect handling and fuel economy,
and are more likely to fail from being
overheated.
Do not overinflate tires. Overinflated tires
can adversely affect handling and ride
comfort, wear unevenly, increase stopping
distance, and result in sudden deflation
(blowout) because they are more likely to
become punctured or damaged by road
debris, potholes etc.
Do not overload the tires by exceeding the
specified load limit or vehicle capacity
weight as indicated on the placard on the
driver’s door B-pillar. Overloading the tires
can overheat them, possibly causing a
blowout.
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.
