The tire inflation pressure monitor*
is temporarily unable to monitor the
tire pressure due to:

the presence of several wheel
sensors in the vehicle


excessive wheel sensor temper-

a nearby radio interference
source


unrecognized wheel sensors
mounted

Remove any additional wheel sensors from
the vehicle, e.g. when transporting a new set
of tires.
As soon as the causes of the malfunction have
been removed, the tire pressure monitor auto-
matically becomes active again.

340 Practical hintsFlat tireSealing 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.

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

Attach the sticker where it will be easily
seen by the driver on the instrument
cluster.

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
Center for assistance or call Roadside
Assistance.

Flat tire

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

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

Replace your TIREFIT container every
four years. Containers are available at
your authorized Mercedes-Benz Cen-
ter.
Sealing tires with TIREFIT kit 2
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).
Warning!
G
Follow recommend tire pressures.
Do not overinflate tires. Overinflating tires
can result in sudden deflation (blowout) be-
cause they are more likely to become punc-
tured or damaged by road debris, potholes,
etc.
Do not underinflate tires. Underinflated tires
wear unevenly, adversely affect handling
and fuel economy, and are more likely to fail
from being overheated.
Do not overload the tires by exceeding the
specified vehicle capacity weight (as indicat-
ed by the label on the pillar in the driver’s
door opening). 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.
Warning!
G
Keep TIREFIT away from sparks, open flame
or heat source.
Do not smoke.

349 Practical hints
Flat tire

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

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

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

Replace your TIREFIT container every
four years. Replacement containers are
available at your authorized
Mercedes-Benz Center.
Warning!
G
If tire 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 pressure is at least 20 psi (1.3 bar), in-
flate tire to correct pressure (see label on
fuel filler flap), and drive vehicle to nearest
tire repair facility to have tire repaired or re-
placed.
Recommended duration of use:
300 miles (500 km) at 50 mph (80 km / h)
with the recommended tire pressure.

Turn the SmartKey in the starter switch
to position1.
or

Press the KEYLESS-GO* start/stop
button on the gear selector lever once
without depressing the brake pedal.

Press I on the electric air pump switch.
The electric air pump should now
switch on and inflate the tire.

Inflate the tire to approx. 36 psi
(2.5 bar).
This takes about five minutes for the
spare tire. Air hose 2 and union
nut3 can become hot duration infla-
tion. Exercise proper caution to avoid
burning yourself when using the equip-
ment.

Press 0 on the electric air pump switch.

Turn the SmartKey in the starter switch
to position0.
or

Press KEYLESS-GO* start/stop button
on the gear selector lever twice without
depressing the brake pedal.
The electric air pump should now be
switched off.

If the tire pressure is above 36 psi
(2.5 bar), release excess tire pressure
using the vent screw.!Do not operate the air pump longer
than eight minutes without interrup-
tion. Otherwise it may overheat.
You may operate the air pump again af-
ter it has cooled off.
