Tires and wheels

Switch on the ignition.

Press button
è
or
ÿ
on the mul-
tifunction steering wheel repeatedly
until the standard display menu ap-
pears in the multifunction display
(
page 118).

Press the
k
or
j
button repeat-
edly until you see the current inflation
pressures for each tire appear in the
display.
Warning!
G
The tire inflation pressure monitor does not
indicate a warning for wrongly selected in-
flation pressures. Always adjust tire inflation
pressure according to the label affixed on
the fuel filler flap.
The tire inflation pressure monitor is not
able to issue a warning due to a sudden loss
of pressure (e.g. tire puncture caused by a
foreign object). In this case bring the vehicle
to a halt by carefully applying the brakes and
avoiding abrupt steering maneuvers.
Warning!
G
Follow recommended inflation pressures.
Do not overinflate tires. Overinflated tires
can result in a sudden deflation (blowout)
because they are more likely to become
punctured or damaged by road debris, pot-
holes etc.
Do not underinflate tires. Underinflated tires
wear unevenly, adversely affect handling
and fuel economy, and are more likely to fail
from being overheated.
Do not overload the tires by exceeding the
specified vehicle capacity weight (as indicat-
ed by the label on the pillar in the driver’s
door opening). Overloading the tires can
overheat them, possibly causing a blowout.iOperating radio transmission equip-
ment (e.g. wireless headsets, two-way
radios) in or near the vehicle could
cause the tire inflation pressure moni-
tor to malfunction.

250OperationTires and wheelsActivating the tire inflation pressure
monitor
You must activate the tire inflation pres-
sure monitor in the following cases:

If you have changed the tire pressure


If you have replaced the wheels or tires


If you have installed new wheels or
tires

Make sure that the tire pressure is cor-
rectly set.

TIRE PRES. MONITOR ACTIVATED

The tire inflation pressure monitor will
now monitor the tire inflation pressure
values of all four tires.
The following message will appear in
the multifunction display field:
TIRE PRES. MONITOR

PRES. DISPLAY AFTER DRIVING A FEW
MINS. REACTIVATE USING R BUTTONThis display appears until the individual
inflation pressure values are matched
with the tires. The individual values are
then displayed.
iIf transporting a deflated road wheel or
additional wheel sensors in the vehicle,
the tire inflation pressure monitor
should not be reactivated until the de-
flated wheel or additional wheel sen-
sors have been removed from the
vehicle. Otherwise, the deflated wheel
or additional sensors could cause the
tire inflation pressure monitor system
to malfunction.

CHECK TIRES!


Check the tire inflation pressures and
correct them if necessary.

Reactivate the tire inflation pressure
monitor.
Rotating wheels
On vehicles with the same wheel size all
around, wheels can be rotated every 3000
to 6000 miles (5000 to 10 000 km), or
sooner if necessary, according to the de-
gree of tire wear. The same direction of tire
rotation must be retained.
Rotate the wheels before the characteris-
tic tire wear pattern becomes visible
(shoulder wear on front wheels and tread
center wear on rear wheels).
Thoroughly clean the inner side of the
wheels after each rotation. Check and en-
sure proper tire inflation pressure. It is
necessary to activate the tire inflation
pressure monitor*.Warning!
G
Rotate front and rear wheels only if they are
of the same size.
!If your vehicle is equipped with a tire in-
flation pressure monitor*, there are
electronic components built into the
wheel.
Do not use mounting tools in the area
of the valve as they could damage the
electronic components.
To prevent damage or incorrect instal-
lation, have the tires changed at an au-
thorized Mercedes-Benz Center.Warning!
G
Have the tightening torque checked after
changing a wheel. Wheels could become
loose if not tightened with a torque of
110 ft.lb. (150 Nm).
Use only genuine Mercedes-Benz wheel
bolts specified for your vehicle's rims.

254OperationMaintenance
MaintenanceWe strongly recommend that you have
your vehicle serviced by your authorized
Mercedes-Benz Center, in accordance with
the Service Booklet at the times called for
by the FSS (Flexible Service System).
Failure to have the vehicle maintained in
accordance with the Service Booklet at the
designated times /mileage called for by
the FSS may result in vehicle damage not
covered by the Mercedes-Benz Limited
Warranty.
FSS will notify you when your next service
is due.
Approximately one month before your next
service is due, one of the following mes-
sages will appear in the multifunction dis-
play while you are driving or when you
switch on the ignition (example service A):SERVICE A IN XXXXX MILES (KM)
SERVICE A IN XXX DAYS
SERVICE A IN X DAY
SERVICE A DUE NOW!
The type of service due is indicated in the
multifunction display:9
Minor service (A)
´
Major service (B)
Clearing the service indicator
The service indicator is automatically
cleared after 30 seconds. You can also
clear it yourself.
Press the reset button
J
(page 22)
in the instrument cluster.
Service term exceeded
If you have exceeded the suggested ser-
vice term, you will see the following mes-
sage in the multifunction display:SERVICE A EXCEEDED BY XXXX MILES (KM)
SERVICE A EXCEEDED BY XXX DAYS
SERVICE A EXCEEDED BY X DAYAn acoustic signal will also sound.
The Mercedes-Benz Center will reset the
service indicator following a completed
service.
iThe interval between services depends
on your driving habits. A gentle driving
style, moderate engine speeds and the
avoidance of short distance trips will
lengthen the interval between services.

SERVICE INTERVAL?
RESET WITH R BUTTON

To confirm, hold down the reset button
until you hear a signal.
The service indicator now displays the
reset interval.
iIf the battery is disconnected, the days
of disconnection will not be included in
the count shown by the service indica-
tor. To arrive at the true service dead-
line, you will need to subtract these
days from the days shown in the ser-
vice indicator.
Do not confuse the service indicator
with the engine oil level indicator
:
.
iIf the service indicator was inadvertent-
ly reset, have a Mercedes-Benz Center
correct it.
Only reset if the proper service has
been performed. Resetting the system
without performing proper service as
called for by the FSS will cause the FSS
to incorrectly determine the next ser-
vice interval which will result in engine
damage not covered by the
Mercedes-Benz Limited Warranty.

l
The red distance indicator lamp
lights up while driving.
You are too close to the vehicle in front of you
to maintain selected speed.

Apply the brakes immediately to in-
crease the following distance.
l
The red distance indicator lamp
comes on while driving and you
hear a warning sound.


You are gaining too rapidly on the vehicle
ahead of you.


The distance warning system has recog-
nized a stationary obstacle on your prob-
able line of travel.

Apply the brakes immediately.

Carefully observe the traffic situation.
You may need to brake or maneuver
to avoid hitting an obstacle.
-
The yellow ABS malfunction indi-
cator lamp comes on while driv-
ing.
The ABS has detected a malfunction and has
switched off. The BAS and the ESP are also
switched off (see messages in display).
The brake system is still functioning normally
but without the ABS available.
If the ABS control unit control unit is malfunc-
tioning, other systems such as Parktronic*,
Distronic*, the navigation system and the au-
tomatic transmission can also malfunction.

Continue driving with added caution.
Wheels may lock during hard braking,
reducing steering capability.

Have the system checked at an autho-
rized Mercedes-Benz Center as soon
as possible.
Failure to follow these instructions in-
creases the risk of an accident.
The charging voltage has fallen below
10 volts and the ABS has switched off.

When the voltage is above this value
again, the ABS is operational again.

If necessary, have the generator and
battery checked.

270 Practical hintsWhat to do if …?Messages in the display
The control system shows warning and
malfunction messages in the multifunction
