amperage, the electric cables could be
overloaded. This could result inafire. There
isarisk of an accident and injury.
Always replace faulty fuses with the specified
new fuses having the correct amperage.
!Only use fuses that have been approved
for Mercedes-Benzvehicles and which
have the correct fuse ratingfor the system
concerned. Otherwise, componentsor
systems could be damaged.
The fuses in your vehicle serve to close down
faulty circuits. Ifafuse blows,all the
componentsonthecircuit and their functions
stop operating.
Blown fusesmust be replacedwith fuses of
the same rating, which you can recognize by
the color and value. The fuse ratings are listed
in the fuse allocation chart.

workshop.
When parking your vehicle,makesure that
thetires do notget deformed by the curb or
other obstacles. If it is necessary to drive over
curbs, speed humps or similar elevations, try
to do so slowly and at an obtuse angle.
Otherwise, the tires, particularly the
sidewalls, may be damaged.
Regular checking of wheels and tires
GWARNING
Damaged tires can cause tire inflation
pressure loss. Asaresult, you could lose
control of your vehicle. There isarisk of
accident.
Check the tires regularly for signs of damage
and replace any damaged tires immediately.
Regularly checkthe wheels and tires of your
vehicle for damage at least onceamonth, as
well as after driving off-road or on rough
roads. Damaged wheels can causealoss of
tire pressure. Pay particular attention to
damage such as:
Rcuts in the tires
Rpunctures
Rtears in the tires
Rbulges on tires
Rdeformation or severe corrosion on wheels
Regularly check the tire tread depth and the
condition of the tread across the whole width
of the tire (Ypage 335). If necessary, turn
the front wheels to full lock in order to inspect
the inner side of the tire surface.
All wheels must haveavalve cap to protect
the valve against dirt and moisture. Do not
mount anything onto the valve other than the
standard valve cap or other valve caps
approved by Mercedes-Benzfor your vehicle.
Do not use any other valve caps or systems,
e.g. tire pressure monitoring systems.
Regularly check the pressure of all the tires
particularly prior to long trips. Adjust the tire
pressure as necessary (Ypage 338).
Observe the notes on the emergencyspare
wheel (Ypage 367).
The service life of tires depends, among other
things, on the following factors:
RDrivingstyle
RTire pressure
RDistance covered
Important safety notes on the tire
tread
GWARNING
Insufficient tire tread will reduce tire traction.
The tire is no longer able to dissipate water.
This means that on wet road surfaces, the risk
of hydroplaning increases, in particular where
speed is not adapted to suit the driving
conditions. There isarisk of accident.
If the tire pressure is too high or too low, tires
may exhibit different levels of wear at
different locations on the tire tread. Thus, you
should regularly check the tread depth and
the condition of the tread across the entire
width of all tires.
Minimum tire tread depth for:
RSummer tires:in (3 mm)
RM+S tires:in (4 mm)
For safety reasons, replace the tires before
the legally prescribed limit for the minimum
tire tread depth is reached.

Tire pressuremonitor
General notes
Ifatire pressure monitor is installed, the
vehicle's wheels have sensors that monitor
the tire pressures in all four tires. The tire
pressure monitor warns you if the pressure
drops in one or more of the tires. The tire
pressure monitor only functions if the correct
sensors are installed on all wheels.
Information on tire pressures is displayed in
the multifunction display. Afterafew minutes
of driving, the current tire pressure of each
tire is shown in theServicemenu of the
multifunction display. For further information
on displaying this message, refer to the
"Checking the tire pressure electronically"
section (Ypage 344).
342Check
Wheels and tires

The tire pressure monitor hasayellow
warning lamp in the instrument cluster for
indicatingapressure loss or malfunction.
Whether the warning lamp flashes or lights up
indicates whetheratire pressure is too low or
the tire pressure monitor is malfunctioning:
Rif the warning lamp is lit continuously, the
tire pressure on one or more tires is
significantly too low. The tire pressure
monitor is not malfunctioning.
Rif the warning lamp flashes for around a
minute and then remains lit constantly, the
tire pressure monitor is malfunctioning.
If the tire pressure monitor is malfunctioning,
it may take more than ten minutes for the tire
pressure warning lamp to inform you of the
malfunction by flashing for approximately one
minute and then remaining lit. When the
malfunction has been rectified, the tire
pressure warning lamp goes out afterafew
minutes of driving.
The tire pressure values indicated by the on-
board computer may differ from those
measured atagas station withapressure
gauge. The tire pressures shown by the on-
board computer refer to those measured at
sea level. At high altitudes, the tire pressure
values indicated byapressure gauge are
higher than those shown by the on-board
computer.Inthis case, do not reduce the tire
pressures.
The operation of the tire pressure monitor can
be affected by interference from radio
transmitting equipment (e.g. radio
headphones, two-way radios) that may be
being operated in or near the vehicle.

Restarting the tire pressuremonitor
When you restart the tire pressure monitor,
all existingwarning messages are deleted and
the warning lamps go out. The monitor uses
the currently set tire pressures as the
reference values for monitoring. In most
cases, the tire pressure monitor will
automatically detect the new reference
values after you have changed the tire
pressure. However, you can also define
reference values manually as described here.
The tire pressure monitor then monitors the
new tire pressure values.
XSet the tire pressure to the value
recommended for the corresponding
driving situation on the Tire and Loading
Information placard on the B-pillar on the
