Notes
The on-board computer shows warnings or
malfunctions in the multi-function display.
Certain display messages are accompanied
by a warning tone or a continuous tone.
The
multi-function display shows high-priority
display messages in red. In the following
tables, these display messages are printed in
red.
Please respond in accordance with the dis-
play messages and follow the additional
notes in this Owner's Manual. G
Risk of accident
No further messages can be displayed if
there is a malfunction in the instrument
cluster and/or the multi-function display.
This

means that you will not see information
about the driving situation, such as the speed, outside temperature, warning/indi-
cator lamps, display messages or system
failures. The vehicle's handling character-
istics may be affected. Adjust your driving
style and speed accordingly.
Immediately consult a qualified specialist
workshop

which has the necessary special-
ist 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 particu-
lar, work relevant to safety or on safety-
related systems must be carried out at a
qualified specialist workshop.
When you stop and park the vehicle, please
observe the instructions provided for HOLD
(Y page 144)and parking ( Y page 103).
The following tables contain all the display
messages. Hiding display messages After a few seconds, the on-board computer
automatically

hides some low priority display
messages. Other messages remain visible in
the multi-function display until you hide them
yourself.
Some high priority display messages cannot
be hidden. The multi-function display shows
these messages continuously until the cau-
ses of the messages have been remedied.
Use the buttons on the multi-function steer-
ing wheel.
X Use the è, ·, j or k button
to select another display.
The on-board computer saves certain dis-
play messages in the message mem-
ory (Y page 121). Practical advice

Flat tyre
282 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.9 Pressure release button
a Pressure gauge
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: press yellow
pressure release button 9 next to pres-
sure gauge a.
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” sticker must be affixed
within the driver's field of vision.
The vehicle's handling characteristics may
be affected.
H Environmental note
Have the used TIREFIT kit disposed of pro-
fessionally, e.g. at a Mercedes-Benz
Service Centre.
X Have the TIREFIT kit replaced every four
years at a qualified specialist workshop,
e.g. a Mercedes-Benz Service Centre.
Changing a wheel and fitting the 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.
Your vehicle's handling characteristics will
be altered when a "Minispare"/collapsible
emergency spare wheel* is fitted. Adapt
your style of driving accordingly.
The “Minispare”/collapsible emergency
spare wheel* must only be used as a tem-
porary measure. Do not exceed the maxi-
mum speed of 80 km/h and do not
deactivate ESP ®
.
Never drive the vehicle with more than one
“Minispare”/collapsible emergency spare
wheel* fitted.
G Risk of accident
Have the “Minispare”/collapsible emer-
gency spare wheel* or the spare wheel*
replaced with a new wheel as soon as pos-
sible at a qualified specialist workshop
which has the necessary specialist knowl-
edge and tools to carry out the work

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
specialist workshop.
Preparing the vehicle X
Prepare the vehicle as described
(Y page 276).
X Place the wheels in the straight-ahead posi-
tion.
X Take the following from the stowage well
beneath the boot floor:
R
the "Minispare"/collapsible emergency
spare wheel* or the spare wheel*
R the vehicle tool kit
R the wheel chock
R the jack
X Secure the vehicle to prevent it from rolling
away.
On level ground: place chocks or similar
under the front and rear of the wheel that
is diagonally opposite the wheel you wish
to change. X
On downhill gradients: place chocks or
similar under both wheels of the other axle.
Raising the vehicle 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. 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.
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. 1
