WARNING
If you manipulate, bridge or replace a faulty
fuse with a fuse of a higher amperage, the
electric cables could be overloaded. This may result in a fire. There is a risk of an accident
and injury.
Always replace faulty fuses with specified new fuses of the correct amperage.
Blown fuses must be replaced with fuses of
the same rating, which you can recognise by 370

the colour and fuse rating. The fuse ratings
are listed in the fuse allocation chart.
The fuse allocation chart is on the fuse box in
the boot (Y page 372).
If the newly inserted fuse also blows, have the cause traced and rectified at a qualified spe-
cialist workshop, e.g. a Mercedes-Benz Ser-
vice Centre.
! Only use fuses that have been approved
for Mercedes-Benz vehicles and which
have the correct fuse rating for the system
concerned. Otherwise, components or sys-
tems could be damaged.
The fuses in your vehicle disconnect faulty
circuits. If a fuse blows, all the components on the circuit and their functions will fail. Before replacing a fuse
X Secure the vehicle against rolling away
(Y page 178).
X Switch off all electrical consumers.
X Make sure that the ignition is switched off
(Y page 159).
or
X When using the key, turn the key to position
0 in the ignition lock and remove it
(Y page 159).
All indicator lamps in the instrument cluster
must be off.
The fuses are located in various fuse boxes:
R Fuse box on the driver's side of the dash-
board
R Fuse box in the front-passenger footwell
R Fuse box in the engine compartment on the
left-hand side of the vehicle, when viewed
in the direction of travel
R Fuse box in the boot on the right-hand side
of the vehicle, when viewed in the direction
of travel Dashboard fuse box
! Do not use a pointed object such as a
screwdriver to open the cover in the dash-
board. You could damage the dashboard or
the cover.
! Make sure that no moisture can enter the
fuse box when the cover is open.
! When closing the cover, make sure that it
is lying correctly on the fuse box. Moisture seeping in or dirt could otherwise impair
the operation of the fuses. X

as possible to check the wheels and tyres for
damage. Hidden tyre damage could also be
causing the unusual handling characteristics.
If you find no signs of damage, have the tyres and wheels checked at a qualified specialist
workshop.
When parking your vehicle, make sure that
the tyres do not get deformed by the kerb or
other obstacles. If it is necessary to drive over
kerbs, speed humps or similar elevations, try
to do so slowly and at an obtuse angle. Oth-
erwise, the tyres, particularly the sidewalls,
may be damaged. Regular checking of wheels and tyres
G
WARNING
Damaged tyres can cause tyre inflation pres-
sure loss. As a result, you could lose control of your vehicle. There is a risk of accident.
Check the tyres regularly for signs of damage and replace any damaged tyres immediately.
Regularly check the wheels and tyres of your
vehicle for damage at least once a month, as well as after driving off-road or on rough
roads. Damaged wheels can cause a loss of
tyre pressure. Pay particular attention to
damage such as:
R cuts in the tyres
R punctures
R tears in the tyres
R bulges on the tyres
R deformation or severe corrosion on wheels
Regularly check the tyre tread depth and the condition of the tread across the whole width
of the tyre (Y page 377). If necessary, turn
the front wheels to full lock in order to inspect
the inner side of the tyre surface.
All wheels must have a valve cap to protect
the valve against dirt and moisture. Do not fit
anything onto the valve other than the stand-
ard valve cap or other valve caps approved for
your vehicle by Mercedes-Benz. Do not fit any other valve caps or systems, e.g. tyre pres-
sure monitoring systems.
Regularly check the pressure of all the tyres,
particularly prior to long trips. Adjust the tyre
pressure as necessary (Y page 380).
The service life of tyres depends on various
factors, including the following:
R driving style
R tyre pressure
R mileage Important safety notes on the tyre
tread
G
WARNING
Insufficient tyre tread will reduce tyre trac-
tion. The tyre is no longer able to dissipate
water. This means that on wet road surfaces, the risk of aquaplaning increases, in particularwhere speed is not adapted to suit the driving
conditions. There is a risk of accident.
If the tyre pressure is too high or too low, tyres may exhibit different levels of wear at differ-
ent locations on the tyre tread. Thus, you
should regularly check the tread depth and
the condition of the tread across the entire
width of all tyres.
Minimum tyre tread depth for:
R summer tyres: 3 mm
R M+S tyres: 4 mm
For safety reasons, replace the tyres before
the legally prescribed limit for the minimum
tyre tread depth is reached. Selecting, fitting and replacing tyres
G
WARNING
Exceeding the stated tyre load-bearing capa-
city and the approved maximum speed could
lead to tyre damage or the tyre bursting. There is a risk of accident.
Therefore, only use tyre types and sizes
approved for your vehicle model. Observe the Operation

ensure that a warning message will only
appear if the tyre pressure drops significantly.
The tyre pressure monitor does not warn you of an incorrectly set tyre pressure. Observe
the notes on the recommended tyre pressure
(Y page 380).
The tyre pressure monitor is not able to warn
you of a sudden loss of pressure, e.g. if the
tyre is penetrated by a foreign object. In the
event of a sudden loss of pressure, bring the
vehicle to a halt by braking carefully. Avoid
abrupt steering manoeuvres.
The tyre pressure monitor has a yellow warn-
ing lamp in the instrument cluster for indicat- ing a pressure loss or malfunction. Depending
on how the warning lamp flashes or lights up, a tyre pressure that is too low or a malfunc-
tion in the tyre pressure monitor is indicated:
R if the warning lamp is lit continuously, the
tyre pressure on one or more tyres is sig-
nificantly too low. The tyre pressure moni-
tor is not malfunctioning.
R if the warning lamp flashes for around a
minute and then remains lit constantly, the tyre pressure monitor is malfunctioning.
i In addition to the warning lamp, a mes-
sage appears in the multifunction display.
You can find further information under:
(Y page 293).
If the tyre pressure monitor is malfunctioning,
it may take more than ten minutes for the tyre pressure warning lamp to inform you of the
malfunction by flashing for approximately one
minute and then remaining lit. When the fault
has been rectified, the tyre pressure warning lamp goes out after you have driven for a few
minutes.
The tyre pressure values indicated by the on- board computer may differ from those meas-
ured at a filling station using a pressure
gauge. The tyre pressures shown by the on-
board computer refer to those measured at
sea level. At high altitudes, the tyre pressure
values indicated by a pressure gauge are
higher than those shown by the on-board computer. In this case, do not reduce the tyre
pressures.
The operation of the tyre pressure monitor
can be affected by interference from radio
transmitting equipment (e.g. radio head-
phones, two-way radios) that may be being
operated in or near the vehicle.

Observe the instructions and safety notes in
the display messages in the "Tyres" section
(Y page 293).
i If the wheel positions on the vehicle are
interchanged, the tyre pressures may be
displayed for the wrong positions for a
short time. After a few minutes of driving,
this is rectified and the tyre pressures are
displayed for the correct positions.
Restarting the tyre pressure monitor When you restart the tyre pressure monitor,
all existing warning messages are deleted and
the warning lamps go out. The monitor uses
the currently set tyre pressures as the refer-
ence values for monitoring. In most cases, the
tyre pressure monitor will automatically
detect the new reference values after you
have changed the tyre pressure. However,
you can also define reference values man-
ually as described here. The tyre pressure
monitor then monitors the new tyre pressure values.
