ChecK tires!
The tire pressure in one or more
tires is already below the minimum
value.

Carefully bring the vehicle to a halt, avoiding
abrupt steering and braking maneuvers.

Change the wheel (

The tire pressure in one or more
tires is low.

Check and correct tire pressure as required
(page 236).
Warning!
G
Do not drive with a flat tire. A flat tire affects
the ability to steer or brake the vehicle. You
may lose control of the vehicle.
Continued driving with a flat tire will cause
excessive heat build-up and possibly a fire.

currently inactive
The tire inflation pressure monitor* is un-
able to monitor the tire pressure due to:

the presence of several wheel sensors
in the vehicle


excessive wheel sensor temperatures


a nearby radio interference source


unrecognized wheel sensors mounted

Check the tire pressure at the next
service station.

Do not drive with a flat tire. A flat tire affects
the ability to steer or brake the vehicle.

ued driving with a flat tire will cause exces-
sive heat build-up and possibly a fire.

302 Practical hintsFlat tire
Flat tireYour vehicle is equipped with a TIREFIT kit
(SL 55 AMG only) or a spare wheel
(SL 500 only).
You can identify which TIREFIT kit
(SL 55 AMG only) you have as follows:

The TIREFIT container of kit 1 is a
squeeze container.


The TIREFIT container of kit 2 is a rigid
container.
Preparing the vehicle
Park the vehicle as far as possible from
moving traffic on a hard surface.

Turn on the hazard warning flashers.

Engage the steering wheel lock in the
straight ahead position and set the
parking brake.

Move the selector lever to P.

Have any passenger exit the vehicle at
a safe distance from the roadway.
Sealing tires with TIREFIT kit 1
Small tire punctures, particularly those in
the tread, can be sealed with TIREFIT.
TIREFIT can be used in ambient tempera-
tures down to -4°F (-20°C).The TIREFIT kit stored in the trunk contains
the TIREFIT container, a filler hose, a valve
stem tool, a valve, and a sticker.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 approx. 0.16 in (4 mm) and tire dam-
age caused by driving with extremely low
tire pressure, or on a flat tire, or a damaged
wheel.
Do not drive the vehicle under such circum-
stances.
Contact your nearest Mercedes-Benz Cen-
ter for assistance or call Roadside
Assistance.

305 Practical hints
Flat tire

Drive the vehicle back and forth very
slowly approximately 30 ft (10 m).
This distributes the TIREFIT sealant ma-
terial inside the tire.

Take the electric air pump out of the
trunk.
1Flap
2Air hose with pressure gauge and vent
screw
3Union nut
4Electrical plug

Open flap 1 on air pump.

Pull out electrical plug 4 and air hose
with the pressure gauge 2.

Screw the air hose 2 onto the tire valve.

Insert electrical plug 4 into vehicle ci-
gar lighter socket.

Turn the key in the ignition to position
1 (
page 29).
or

Press the KEYLESS-GO* start/stop
button on the selector lever once. Do
not depress brake pedal.

Press I on the electric air pump switch.
The electric air pump should now
switch on and inflate the tire.
After 5 minutes, the pressure gauge must
display at least 26 psi (1.8 bar). The air
hose and the union nut can become hot
during inflation. Please exercise appropri-
ate caution.

If this tire pressure is not attained, turn
off the electric air pump, detach the air
hose from the tire valve, and again
drive vehicle back and forth very slowly
approximately 30 ft (10 m).
This serves to better distribute the
TIREFIT sealant material inside the tire.

Inflate the tire again.
Warning!
G
Observe safety instructions on air pump la-
bel.

306 Practical hintsFlat tire
Press 0 on the electric air pump switch.

Turn the key in the ignition to
position0.
or

Press KEYLESS-GO* start/stop button
on the selector lever twice. Do not de-
press brake pedal.
The electric air pump should now be
switched off.

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
10 minutes, check tire pressure using
the pressure gauge on the air pump.
!Do not operate the electric air pump
longer than eight minutes without in-
terruption. Otherwise it may overheat.
You may operate the air pump again af-
ter it has cooled off.
Warning!
G
If a tire pressure of 26 psi (1.8 bar) is not at-
tained, 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.
