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.
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, 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.

422 Practical hintsFlat tire
After attaining a tire inflation pressure
of 26 psi (1.8 bar), press 0 on electric
air pump switch8.
The electric air pump should now be
switched off.

Turn the SmartKey in the starter switch
to position0 (
page 36).

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, 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.
If tire inflation pressure is at least
20 psi (1.3 bar), inflate tire to correct pres-
sure (see placard on the driver’s door
B-pillar), and drive vehicle to nearest tire re-
pair facility to have tire repaired or replaced.
Recommended duration of use:
300 miles (500 km) at 50 mph (80 km/h)
with the recommended tire inflation pres-
sure.


424 Practical hintsFlat tirePreparing the vehicle
Prepare the vehicle as described under
“Preparing the vehicle” on this page.
Take the spare wheel out of the trunk
(page 398).

Take the wheel wrench and the jack
out of the trunk (
page 398).
Lifting the vehicle

Prevent the vehicle from rolling away
by blocking wheels with wheel chocks
or other sizeable objects.
When changing wheel on a level surface:

Place the wheel chock in front of and
another 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 and the other size-
able object as follows:

Place the wheel chock and another
sizeable object on the downhill side
blocking both wheels of the axle not
being worked on.
1Wheel wrench

On wheel to be changed, loosen but do
not yet remove the wheel bolts (ap-
proximately one full turn with
wrench1).
Warning!
G
The jack is designed exclusively for jacking
up the vehicle at the jack take-up brackets
built into either side of the vehicle. To help
avoid personal injury, use the jack only to lift
the vehicle during a wheel change. Never
get beneath the vehicle while it is supported
by the jack. Keep hands and feet away from
the area under the lifted vehicle. Always
firmly set parking brake and block wheels
before raising vehicle with jack.
Do not disengage parking brake while the
vehicle is raised. Be certain that the jack is
always vertical (plumb line) when in use, es-
pecially on hills. Always try to use the jack
on level surface. Be sure that the jack arm is
fully seated in the jack take-up bracket. Al-
ways lower the vehicle onto sufficient ca-
pacity jackstands before working under the
vehicle.

behind flap1 and place the air pump
back in the trunk.
!Do not operate the air pump longer
than 8 minutes without interruption.
Otherwise it may overheat.
You may operate the air pump again
after it has cooled off.
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.

(130 Nm).

Before storing the jack in the trunk, it
should be fully collapsed.
MOExtended system*
The MOExtended system allows you to
continue driving your vehicle even if there
is a total loss of pressure in one or more
tires.
You may only use the MOExtended system
in conjunction with the Run Flat Indicator*
or the Advanced TPMS* (Canada only)
(page 314).
Warning!
G
Have the tightening torque checked after
changing a wheel. The wheels could come
loose if they are not tightened to a torque of
96 lb-ft (130 Nm).iWrap the damaged wheel in the protec-
tive film that comes with the spare
wheel and put the wheel in the trunk.
You can also place the damaged wheel
down into the spare wheel well. In this
case, you must stow the luggage bowl
in the trunk.
!The maximum distance in emergency
mode depends on the vehicle’s load. It
is 30 miles (50 km) if the vehicle is par-
tially loaded and 18 miles (30 km) if the
vehicle is fully loaded.
The point at which the maximum driv-
ing distance begins in emergency
mode is when the warning message
appears in the multifunction display
indicating that there is a loss of tire
inflation pressure.
Do not exceed the maximum speed of
50 mph (80 km/h).
