Tire pressure
Check tires
The tire inflation
pressure in one or
more tires is already
below the minimum
value.
The tire inflation
pressure in one or
more tires is low.
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 correct tire infla-
tion pressure as required.
Temporarily repair tire using TIREFIT (
page 351) 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.
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) an make sure
the tires rotate in the direction specified
(page 257). 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 po-
sition.
Set the parking brake.
Move the gear selector lever to P.
Turn off the engine (
page 58).
Remove the SmartKey from the starter
switch.
Open the driver’s door.
Have any passenger exit the vehicle at
a safe distance from the roadway.
Sealing tires with TIREFIT kit
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 elec-
tric air pump out of the trunk.
!A wheel change should only be carried
out at an authorized Mercedes-Benz
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.

Screw the air pump’s air hose5 onto
flange6 of the TIREFIT container.
Stick TIREFIT container1 upside
down into notch3 of the electric air
pump.
Warning!
G
Take care not to allow the contents of
T I R E F I T t o c o m e i n c o n t a c t w i t h h a i r , e y e s o r
clothing. TIREFIT is harmful if inhaled, swal-
lowed 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.iIf sealant has leaked out, let it dry. You
can then peel it off.

Unscrew the valve cap from tire
valve7.
Screw filler hosea onto tire valve7.
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 interrup-
tion. Otherwise it may overheat.
You may operate the air pump again af-
ter it has cooled off.
