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.
iIf sealant has leaked out, let it dry. You can
then peel it off.
Warning!G
Observe safety instructions on air pump
label.
iYour vehicle may be equipped with either of
two versions of the electric air pump:

Version 1
The air hose with pressure gauge and the
electrical plug are located behind a flap.

Version 2
The pressure gauge is located in the pump
housing.
The following description applies to both
versions. Differences in usage are expressly
declared.

Flat tire
After attaining a tire inflation pressure
of 26 psi (1.8 bar), press0 on electric
air pump switch8 (
page 403).
The electric air pump is switched off.
Turn the SmartKey in the starter switch
to position0 (
page 37).
Detach the electric air pump.
The air hose may still be hot. Please
exercise appropriate caution.
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 the vehicle for an initial
10 minutes, check the tire inflation
pressure using pressure gauge 9 on
the air pump.
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.

Version 2
aDeflate button
bPressure gauge
If the tire inflation pressure is at least
20 psi (1.3 bar), inflate or deflate the
tire to correct tire inflation pressure
(see placard on the driver’s door
B-pillar):
To increase tire inflation pressure:
Switch on the electric air pump.
To decrease tire inflation pressure
(version 1): Open vent screwa
on pressure gaugeb
(
page 404).
To decrease tire inflation pressure
(version 2): Press yellow deflate
buttona located in air pump hous-
ing next to pressure gaugeb.Drive to the nearest qualified work-
shop, 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
50 mph (80 km/h) or below with the
recommended tire inflation pressure.
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
Follow recommend inflation pressures.
Do not overinflate tires. Overinflating tires
can result in sudden deflation (blowout)
because they are more likely to become
punctured 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.

Preparing the vehicle
Prepare the vehicle as described
(
page 401).
Take the spare wheel, wheel wrench,
wheel bolts, jack, and electric air pump
out of the trunk (
page 382).Lifting the vehicle
Prevent the vehicle from rolling away
by blocking wheels with wheel chocks
(not included) or other sizeable ob-
jects.
One wheel chock is included with the
vehicle tool kit (
page 383).
When changing wheel on a level surface:
Place one wheel chock or other size-
able object in front of and another
wheel chock or other sizeable object
behind the wheel that is diagonally
opposite to the wheel being changed.
Always try lifting the vehicle using the jack
on a level surface. However, should cir-
cumstances require you to do so on a hill,
place the wheel chock or other sizeable
object and the other wheel chock or other
sizeable object as follows:
Place wheel chocks and other sizeable
objects on the downhill side blocking
both wheels of the axle not being
worked on.
Warning!G
The dimensions of the spare wheel are dif-
ferent from those of the road wheels. As a
result, the vehicle handling characteristics
change when driving with a spare wheel with
collapsible tire mounted. Adapt your driving
style accordingly.
The spare wheel is for temporary use only.
When driving with spare wheel mounted,
ensure proper tire inflation pressure and do
not exceed vehicle speed of 50 mph
(80 km/h).
Drive to the nearest Mercedes-Benz Center
as soon as possible to have the spare wheel
replaced with a regular road wheel.
Never operate the vehicle with more than
one spare wheel mounted.
Do not switch off the ESP
® when a spare
wheel is mounted.
