Please correct
the tire pressure.
The tire inflation pres-
sure is too low in one or
more tires.

Check and correct tire inflation pressure as required
(page 270).
Caution
Tire Defect
One or more tires are
deflating.
The respective tire is in-
dicated in the multi-
function display.

Carefully bring the vehicle to a halt, avoiding abrupt steering and
braking maneuvers. Observe the traffic situation around you.

Temporarily repair tire using TIREFIT (
page 365) or contact
Roadside Assistance. If tire cannot be temporarily repaired using
TIREFIT, contact Roadside Assistance.

Have the damaged wheel repaired or replaced at an authorized
Mercedes-Benz Center.
Check Tires
The tire inflation pres-
sure in one or more
tires is already below
the minimum value.
The respective tire is in-
dicated in the multi-
function display.

Carefully bring the vehicle to a halt, avoiding abrupt steering and
braking maneuvers. Observe the traffic situation around you.

Check the tires. If no damage visible, check and adjust tire pres-
sure as required.

Temporarily repair tire using TIREFIT (
page 365) or contact
Roadside Assistance. If tire cannot be temporarily repaired using
TIREFIT, contact Roadside Assistance.

Have the damaged wheel repaired or replaced at an authorized
Mercedes-Benz Center.

352 Practical hintsWhat to do if ...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.
Warning!
G
Have worn or damaged tires replaced in
pairs (front pair or rear pair) and 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.

The vehicle is equipped with the TIREFIT
kit.Preparing the vehicle
Park the vehicle in a safe distance from
moving traffic on a hard, flat surface
when possible.

Turn on the hazard warning flashers.

Turn the steering wheel so that the
front wheels are in a straight ahead
position.

Set the parking brake.

Move the gear selector lever to park
positionP.

Turn off the engine (
page 56).

Remove the SmartKey from the starter
switch.

Have any passenger exit the vehicle at
a safe distance from the roadway.
Sealing tires with TIREFIT
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).

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

Take TIREFIT, the sticker, and the
electric air pump out of the trunk.
!
A wheel change should only be carried out
at an authorized Mercedes-Benz Center. Other-
wise there is a danger of damaging the vehicle by
jacking it up incorrectly.
i
Open door only when conditions are safe to
do so.
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
circumstances.
Contact your nearest Mercedes-Benz
Center for assistance or call Roadside
Assistance. !
After using TIREFIT, the tire inflation
pressure sensor may have to be replaced.

Warning!
G
Take care not to allow the contents of
TIREFIT to come in contact with hair, eyes or
clothing. TIREFIT is harmful if inhaled,
swallowed or absorbed through the skin -
causes skin, eye and respiratory irritation.
Any contact with eyes or skin should be
flushed immediately with plenty of water.
If clothing comes in contact with TIREFIT,
change clothing as soon as possible.
In case of allergic reaction or rash, consult a
physician immediately.Warning!
G
Keep TIREFIT out of reach of children.
If swallowed, rinse mouth immediately with
plenty of water and drink plenty of water.
Do not induce vomiting!
Consult a physician immediately.
Keep away from open flame or heat source.
i
If sealant has leaked out, let it dry. You can
then peel it off.
If you get sealant on your clothing, have it dry-
cleaned as soon as possible.

down into notch3 of the electric air
pump.

Screw filler hosea onto tire valve7.

Close vent screw9 on pressure
gauge.

Insert electrical plug4 into vehicle
cigarette lighter socket.

Turn the SmartKey in the starter switch
to position1 (
page 40).

PressI on electric air pump switch8.
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 can become hot during inflation.
Please exercise appropriate caution.

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

Unscrew the air pump’s air hose5
from flange6 of the TIREFIT
container.

Screw air hose5onto tire valve7.

Inflate the tire again.
Warning!
G
Observe safety instructions on air pump
label.
!
Do not operate the electric air pump longer
than 8 minutes without interruption. Otherwise it
may overheat.
You may operate the air pump again after it has
cooled off.


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.
