lowed or absorbed through the skin. It caus-
es 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.

5Filler hose plug
6Tire valve core
Unscrew the valve cap from valve1.

Remove tire valve core6 from valve
stem1 using valve stem tool2. Keep
tire valve core6 clean and dry.

Remove plug5 from end of hose4.

Push hose4 onto valve stem1.

Hold TIREFIT container3 upside down
(hose down) and squeeze firmly several
times until entire contents of the con-
tainer are in tire.

Pull hose4 off and screw tire valve
core6 tightly into the valve stem1
using valve stem tool2.

Reinstall valve cap on valve stem1.

Install plug5 onto end of hose4.

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

Take the electric air pump out of the
trunk (
page 208).
iIf the removed tire valve core is dirty,
use the spare tire valve core stored
with the valve stem tool.
iIf sealant has leaked out, let it dry. You
can then peel it off.

233 Practical hints
Flat tire

Detach the electric air pump.

Reinstall tire valve cap.

Store the electrical plug and the air
hose behind the flap and place the air
pump back into 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.
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
To prevent possible injury when unscrewing
air pump filler hose from tire valve after in-
flating the tire, use a rag since the tire valve
could be hot.
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 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 Assis-
tance.
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.

TIREFIT is a limited repair device. TIREFIT
cannot be used for:

cuts or punctures larger than approx.
0.16 in (4 mm)


on a flat tire, or a damaged wheel


tire damage caused by driving with ex-
tremely low tire pressure
Do not drive the vehicle under such circum-
stances.
Contact your nearest Mercedes-Benz
Center for assistance or call Roadside Assis-
tance.
Warning!
G
Observe safety instructions on air pump la-
bel.iIf sealant has leaked out, let it dry. You
can then peel it off.

Detach the electric air pump.
The air hose may still be hot. Please ex-
ercise appropriate caution.

I f ti re pre s su re is a t l ea s t 2 0 ps i (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.
Warning!
G
Follow recommend inflation 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.

238 Practical hintsFlat 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. Replacement containers are
available at your authorized
Mercedes-Benz Center.
Mounting the spare wheel
More information on spare wheels with
collapsible tires can be found in the “Tech-
nical data” section (
page 265).Preparing the vehicle
Prepare the vehicle as described under
“Preparing the vehicle” on page
(
page 229).

Turn pump holder counterclockwise to
loosen (
page 207).

Take the spare wheel out of wheel well.
Lifting the vehicle

Prevent the vehicle from rolling away
by blocking wheels with wheel chocks
(not included) or other sizable objects.
When changing wheel on a level surface:

Place one chock in front of and one be-
hind the wheel that is diagonally oppo-
site to the wheel being changed.
When changing wheel on a hill:

Place chocks on the downhill side
blocking both wheels of the other axle.

Take the vehicle tool kit and the jack
out of the trunk.
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
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
mounted. Adapt your driving style accord-
ingly.
The spare wheel is for temporary use only.
When driving with spare wheel mounted, en-
sure proper tire 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.

Observe 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.
