X
Press on/off switch ?on the electric air
pump to I.
The electric air pump is switched on. The
tyre is inflated.
i First, TIREFIT is pumped into the tyre. The
pressure can briefly rise to around 5 bar.
Do not switch off the electric pump dur-
ing this phase.
X Let the electric pump run for five minutes.
The tyre should then have a pressure of at
least 1.8 bar.
! Do not operate the electric air pump for
longer than eight minutes at a time without
a break. It may otherwise overheat.
The air pump can be operated again once
it has cooled down.
If a pressure of 1.8 bar is not reached
after five minutes:
X Switch off and disconnect the electric air
pump and drive the vehicle forwards or
backwards approximately 10 m.
This distributes the TIREFIT more evenly.
X Pump up the tyre again. G
Risk of accident
If a pressure of 1.8 bar is not achieved after
five minutes, the tyre is too badly damaged.
Do not drive any further. Consult a qualified
specialist workshop which has the necessary
specialist knowledge and tools to carry out
the work required. Mercedes-Benz recom-
mends that you use a Mercedes-Benz Service
Centre for this purpose. In particular, work
relevant to safety or on safety-related sys-
tems must be carried out at a qualified spe-
cialist workshop.
When a tyre pressure of at least 1.8 bar
is reached:
X Press on/off switch ?on the electric air
pump to 0.
The electric air pump is switched off.
X Remove the TIREFIT kit from the wheel. !
After use, excess TIREFIT may run out of
the filler hose. This may cause stains.
Therefore, place the filler hose in the plastic
which contained the TIREFIT kit.
X Stow away the TIREFIT kit, the electric air
pump and the warning triangle.
X Pull away immediately.
X Stop after driving for approximately ten
minutes and check the tyre pressure with
the electric air pump. G
Risk of accident
If the tyre pressure is now lower than 1.3 bar,
the tyre is too badly damaged. Do not drive
any further. Consult a qualified specialist
workshop which has the necessary specialist
knowledge and tools to carry out the work
required. Mercedes-Benz recommends that
you use a Mercedes-Benz Service Centre for
this purpose. In particular, work relevant to
safety or on safety-related systems must be
carried out at a qualified specialist workshop.
X If the tyre pressure is still at least 1.3 bar,
correct it (see fuel filler flap for values).
To increase the tyre pressure: switch on
the electric air pump.
To reduce the tyre pressure: open pres-
sure release screw Fon pressure
gauge G.
X Drive to the nearest workshop and have the
tyre changed there.
X Have the TIREFIT kit replaced as soon as
possible at a qualified specialist workshop,
e.g. at a Mercedes-Benz Service Centre. G
Risk of accident
Do not exceed the maximum speed of
80 km/h.
The "max. 80 km/h" label must be affixed in
the driver's field of vision.
The vehicle's handling characteristics may be
affected. Flat tyre

Changing a wheel and fitting the
spare wheel G
Risk of accident
The wheel dimensions and tyre size of the
"Minispare" emergency spare wheel *may dif-
fer from those of the damaged wheel.
Your vehicle's handling characteristics will
change when a "Minispare" emergency spare
wheel* is fitted. Adapt your style of driving
accordingly.
The "Minispare" emergency spare wheel*
may only be used for a short time. Do not
exceed the maximum speed of 80 km/h and
do not deactivate ESP ®
.
Never drive the vehicle with more than one
"Minispare" emergency spare wheel* fitted. G
Risk of accident
Have the "Minispare" emergency spare
wheel* or the spare wheel* replaced with a
new wheel as soon as possible at a qualified
specialist workshop which has the necessary
specialist knowledge and tools to carry out
the work required. Mercedes-Benz recom-
mends that you use a Mercedes-Benz Service
Centre for this purpose. In particular, work
relevant to safety or on safety-related sys-
tems must be carried out at a qualified spe-
cialist workshop.
Preparing the vehicle X
Prepare the vehicle as described
(Y page 262).
X If a trailer is coupled, uncouple it.
X Place the wheels in the straight-ahead posi-
tion.

On downhill gradients: place the folding
wheel chock or similar behind the wheels
of the front and rear axle. X
Using wheel wrench ?, loosen the bolts on
the wheel you wish to change by about one
full turn. Do not unscrew the bolts com-
pletely.
X Remove the spare wheel from the exterior
bracket* (Y page 210).
or
X Remove the "Minispare" emergency spare
wheel* from the stowage well under the
luggage compartment floor (Y page 210).
Raising the vehicle G
Risk of injury
The jack is designed only to raise the vehicle
for a short time while a wheel is being
changed.
The vehicle must be placed on stands if you
intend to work under it.
Make sure that the jack is placed on a firm,
non-slip, level surface. Do not use wooden
blocks or similar objects as a jack underlay.
The vehicle could otherwise fall off the jack
and seriously injure you.
Do not start the engine at any time while the
wheel is being changed.
Do not lie under the vehicle when it is being
supported by the jack. If you do not raise the
vehicle as described, it could slip off the jack (e.g. if the engine is started or a door or the
tailgate is opened or closed), and you could
be seriously injured.
G
Risk of accident
If you fail to position the jack correctly, the
vehicle may:
R slip off the jack
R injure you or others
R be damaged
Thus, it is important to make sure that the jack
is positioned correctly in the respective jack-
ing points. Before positioning the jack,
remove any dirt that may have collected in the
jacking points.
The jacking points for the jack are located
behind the wheel housings of the front wheels
and in front of the wheel housings of the rear
wheels (arrows). X
