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 Remove TIREFIT sealant filler bottle 1
from the electric pump.
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 neces-
sary specialist knowledge and tools to carry
out the work required. Mercedes-Benz rec-
ommends that you use a Mercedes-Benz
Service Centre for this purpose. In particu-
lar, work relevant to safety or on safety-
related systems must be carried out at a
qualified specialist workshop.
If a tyre pressure of 1.8 bar is reached:
X Press on/off switch 4on the electric air
pump to 0.
The electric air pump is switched off.
X Disconnect the electric air pump and stow
it away. X
Fold up the warning triangle and stow it
away.
X Pull away immediately.
This distributes the TIREFIT more evenly
around the tyre.
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 neces-
sary specialist knowledge and tools to carry
out the work required. Mercedes-Benz rec-
ommends that you use a Mercedes-Benz
Service Centre for this purpose. In particu-
lar, 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 aon pressure
gauge b.
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.

327Changing a wheel/fitting the emer-
gency spare wheel*
G
Risk of accident
The wheel dimensions and tyre size of the
spare wheel*, the emergency spare
wheel* and standard wheels may differ
from one another.
The handling characteristics of your vehicle
will change if you fit an emergency spare
wheel*. Adapt your style of driving accord-
ingly.
You may only use the emergency spare
wheel* for a short while. Do not exceed the
maximum speed of 80 km/h and do not
deactivate ESP ®
.
Never drive the vehicle with more than one
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 quali-
fied specialist workshop which has the nec-
essary specialist knowledge and tools to
carry out the work required. Mercedes-
Benz recommends that you use a
Mercedes-Benz Service Centre for this pur- pose. In particular, work relevant to safety
or on safety-related systems must be car-
ried out at a qualified specialist workshop.
Preparing the vehicle X

bracket (Y page 256).
or
X Remove the "Minispare" emergency spare
wheel from the stowage compartment
under the luggage compartment floor
(Y page 256).
Raising the vehicle G
Risk of injury
The jack is designed only to raise the vehi-
cle for a short time while a wheel is being
changed.
If you intend to work under the vehicle, it
must be placed on stands.
Make sure that the jack is placed on a firm,
non-slip, level surface. Do not use wooden
blocks or similar items as jacking supports.
Otherwise, the jack will not be able to ach-
ieve its load-bearing capacity due to the
restricted height.
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
It is thus important to ensure that the jack
is positioned correctly in the respective
jacking points. Before positioning the jack,
remove any dirt that may have collected in
the jacking points. 1
Wheel wrench X
Using wheel wrench 1, loosen the bolts on
the wheel you wish to change by about one
full turn. Do not unscrew the bolts com-
pletely.
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). Practical advice

330 safety reasons, Mercedes-Benz recom-
mends that you only use wheel bolts which
have been approved for Mercedes-Benz
vehicles. Other bolts could work loose.
Do not tighten the wheel bolts completely
while the vehicle is still jacked up. The vehi-
cle could topple off the jack. 1
Wheel bolts for 18", 19" and 20" wheels
2 Wheel bolts for 17" wheels or the
"Minispare" emergency spare wheel*
! Always use wheel bolts 2to fit 17"
wheels or the "Minispare" emergency spare
wheel*. Using other wheel bolts when fit-
ting 17" wheels or the "Minispare" emer-
gency spare wheel* could damage the
brake system. i
Wheel bolts 2can be found together
with the "Minispare" emergency spare
wheel* (not with 17" tyres).
X Clean the wheel and wheel hub contact
surfaces. X

Do not activate the tyre pressure moni-
tor* until the deflated tyre has been
removed from the vehicle. MOExtended run-flat system*
The MOExtended run-flat system must only
be used in conjunction with the tyre pressure
loss warning system*.
! The maximum permissible distance which
can be driven in run-flat mode depends on
the load in the vehicle. It is 50 km if the
vehicle is partially laden and 30 km if fully
laden.
The maximum range that can be driven in
emergency operation is measured from the
point at which the pressure loss warning
message appears in the multi-function dis-
play.
You must not exceed a maximum speed of
80 km/h. G
Risk of accident
The handling characteristics of your vehicle
deteriorate in run-flat mode, for example: R
when cornering
R when braking
R when accelerating rapidly
Adapt your driving style accordingly and
avoid sudden changes in direction and sud-
den acceleration, as well as driving over
obstacles (i.e. kerbs, potholes), and driving
off-road. This is particularly the case when
the vehicle is heavily laden.
The maximum permissible distance that
can be driven in run-flat mode depends to
a large extent on the loads placed on the
vehicle. It can be shorter due to high
speeds, a heavy load, sudden acceleration
and/or manoeuvring, the road surface con-
dition, outside temperature, etc., or further
if you drive carefully and conservatively.
Do not continue to drive in run-flat mode if:
R you hear banging noises
R the vehicle starts to shake
R you see smoke and smell rubber
R ESP ®
is intervening constantly
R there are tears in the sidewalls of the tyre
After driving in run-flat mode, you must
have the rims checked for damage at a qualified specialist workshop which has the
necessary specialist knowledge and tools
to carry out the work required. The faulty
tyre must be replaced in every case.
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 work-
shop.
i On a vehicle with MOExtended tyres, only
use MOExtended spare tyres. These must
be of the size specified for the vehicle. Practical advice
