Each tire, including the spare (if provided), should be checked at least every two weeks when
cold and inflated to the pressure recommended by the vehicle manufacturer on the Tire and
Loading Information placard on the driver's door B-pillar or, if available, the tire pressure label
on the inside of the fuel filler flap. If your vehicle has tires of a different size than the size indicated
on the Tire and Loading Information placard or the tire pressure label, you should determine the
proper tire pressure for those tires.
As an added safety feature, your vehicle has been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires are
significantly underinflated. Accordingly, when the low tire pressure telltale illuminates, you should
stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving
on a significantly underinflated tire causes the tire to overheat and can lead to tire failure.
Underinflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling
and stopping ability. Please note that the TPMS is not a substitute for proper tire maintenance,
and it is the driver's responsibility to maintain correct tire pressure, even if underinflation has
not reached the level to trigger illumination of the TPMS low tire pressure telltale.
USA only:
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the
system is not operating properly. The TPMS malfunction indicator is combined with the low tire
pressure telltale. When the system detects a malfunction, the telltale will flash for approximately
1 minute and then remain continuously illuminated. This sequence will be repeated every time

Preparing the vehicle
Your vehicle may be equipped with:
R TIREFIT kit 30
R a "Minispare" emergency spare wheel
R a collapsible spare wheel
R MOExtended tires (tires with run-flat
properties) ( Y page 334)
i Vehicle preparation is not necessary on
vehicles with MOExtended tires.
i Vehicles equipped with MOExtended tires
are not equipped with a TIREFIT kit at the
factory. It is therefore recommended that
you additionally equip your vehicle with a
TIREFIT kit if you mount tires that do not
feature run-flat properties, e.g. winter tires.
A TIREFIT kit can be obtained from an
authorized Mercedes-Benz Center.
XVehicles with AIRMATIC: make sure that
"normal" level is selected ( Y page 189).XStop the vehicle as far away as possible
from traffic on solid, non-slippery and level
ground.XSwitch on the hazard warning lamps.XFirmly depress the parking brake.XBring the front wheels into the straight-

TIREFIT kit
Using the TIREFIT kit
You can use the TIREFIT kit to seal small
punctures, particularly those in the tire tread.
You can use TIREFIT at outside temperatures
down to -4 ‡ (-20 †).
GWARNING
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 the nearest authorized Mercedes-
Benz Center for assistance or call Roadside
Assistance.
XDo not remove any foreign objects which
have penetrated the tire, e.g. screws or
nails.XRemove the tire sealant bottle, the
accompanying "max. 80 km/h" sticker and
the tire inflation compressor from the
stowage well underneath the trunk floor/
trunk floor ( Y page 322).XAffix part : of the sticker within the
driver's field of vision.XAffix part ; of the sticker near the valve
on the wheel with the defective tire.GWARNING
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.
GWARNING
Keep TIREFIT away from children. If
swallowed, rinse mouth immediately with
plenty of water and drink plenty of water.
Do not induce vomiting.
Consult a doctor immediately.
Keep away from open flame or heat source.

compressor to I.
The tire inflation compressor is switched
on. The tire is inflated.
i First, TIREFIT is pumped into the tire. The
pressure can briefly rise to approximately
500 kPa (5 bar/73 psi).
Do not switch off the tire inflation
compressor during this phase.
XAllow the tire inflation compressor to run
for five minutes. The tire should then have
attained a pressure of at least 180 kPa
(1.8 bar/26 psi).
! Do not operate the tire inflation
compressor for longer than eight minutes
at a time without a break. It may otherwise
overheat.
The tire inflation compressor can be
operated again once it has cooled down.
If a pressure of 180 kPa (1.8 bar/26 psi) has
been achieved after five minutes, see
( Y page 328).
If a pressure of 180 kPa (1.8 bar/26 psi) has
not been achieved after five minutes, see
( Y page 327).
Tire pressure of at least 180 kPa
(1.8 bar/26 psi) is not reached
If, after five minutes, a pressure of 180 kPa
(1.8 bar/26 psi) has not been achieved:
XPress the on/off switch on the tire inflation
compressor to 0.

GWARNING
If after five minutes a pressure of 180 kPa
(1.8 bar/26 psi) cannot be achieved, the tire
is too badly damaged to be repaired reliably
using TIREFIT.
In this case TIREFIT cannot seal the tire
properly.
Do not drive any further.
Contact the nearest authorized Mercedes-
Benz Center for assistance or call Roadside
Assistance.
Tire pressure of 180 kPa (1.8 bar/
26 psi) is reached
XPress the on/off switch on the tire inflation
compressor to 0.
The tire inflation compressor is switched
off.XUnscrew the filler hose from the valve of
the faulty tire.

the filler hose. This could cause stains.
Therefore, place the filler hose in the plastic
bag which contained the TIREFIT kit.
XStow the tire sealant bottle and the tire
inflation compressor.XPull away immediately .GWARNING
Do not exceed a 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
instrument cluster where it will be easily seen
by the driver.
Vehicle handling characteristics of a TIREFIT
repaired tire may change. Adapt your driving
accordingly.
XStop after driving for approximately ten
minutes and check the tire pressure with
the tire inflation compressor.GWARNING
