Version 1
aVent screw
bPressure gauge
Close vent screwa on pressure
gaugeb (version 1 only).
Screw filler hose8 onto tire valve9
(
page 403).
Insert electrical plug4 (page 403)
into the cigarette lighter (
page 256).
Turn the SmartKey in the starter switch
to position1 (
page 37).
PressI on electric air pump switch3
(
page 403).
The electric air pump is switched on
and inflates the tire.
Let the electric air pump inflate the tire
for approximately 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 the tire inflation pressure of at least
26 psi (1.8 bar) is not attained, turn off
the electric air pump by pressing0 on
electric air pump switch3
(
page 403).
Detach filler hose8 f r o m t i r e v a l v e9
(
page 403).
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 TIREFIT container1
(
page 403).
Screw air hose5onto tire valve9.
Inflate the tire again.
iFirst, the sealing is pumped into the tire. The
pressure may briefly rise to up to 73 psi (5 bar).
This is normal and not an indication of a malfunc-
tion. Do not switch off the electric air pump.
!Do not operate the electric air pump longer
than 6 minutes without interruption. Otherwise it
may overheat.
You may operate the air pump again after it has
cooled off.

Flat tire
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*
(
page 315).
!The maximum distance in emergency mode
depends on the vehicle’s load. It is 30 miles
(50 km) if the vehicle is partially loaded and
18 miles (30 km) if the vehicle is fully loaded.
The point at which the maximum driving 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).
Warning!G
In emergency mode, your vehicle’s driving
characteristics are diminished in such situa-
tions as:
driving around curves
while braking
while accelerating rapidly
Therefore, your driving style must be adapt-
ed accordingly. Avoid abrupt steering and
driving maneuvers, as well as driving over
obstacles (road curbs, potholes, or off-road
areas). This is especially important if the
vehicle is heavily loaded.
The emergency driving distance that can be
achieved greatly depends on the demands
placed on the vehicle. Depending on speed,
load, driving maneuvers, road conditions,
outside temperature, etc., the distance can
be significantly shorter or, if the vehicle is
driven cautiously, somewhat longer.
Do not continue driving in emergency mode
if
you notice knocking sounds
the vehicle starts to shake
smoke develops and you smell rubber
ESP® is intervening continuously
you notice tears on the tire sidewalls
After driving in emergency mode, you must
have the rims inspected by an authorized
Mercedes-Benz Center to check if they are
suitable for further use. The failed tire must
be replaced in any case.
iWhen replacing individual or all tires on the
vehicle, make sure only tires marked
with“MOExtended” are mounted in the size
specified for your vehicle (
page 434).
