tsafety notes G
WARNING
If yo umanipulate, bridge or replace afaulty
fuse with afuse of ahigher amperage ,the
electric cables coul dbeoverloaded. This may
result in afire. There is arisk of an accident
and injury.
Always replace faulty fuses with specified new fuses of the correct amperage. The fuses in your vehicle disconnect fault
ycir-
cuits. If afuse blows, all the components in the
circuit and their functions will fail.
Blown fuses must be replaced with fuses of the same rating, which you can recognise by the
colour and fuse rating. The fuse ratings are listed
in the fuse allocation chart (Y page 233).
If the newly inserted fuse also blows, have the
cause traced and rectified at aqualified special-
ist workshop, e.g. aMercedes-Benz Service
Centre.
! Only use fuses that have been approved for
Mercedes-Benz vehicles and which have the
correc tfuse rating for the system concerned.
Otherwise, components or systems could be
damaged.
! 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 seep-
ing in or dirt could otherwise impair the oper-
ation of the fuses. Bef

Regularly check the tyre tread depth and the
condition of the tread across the whole width of
the tyre (Y page 236). In order to inspect the
inner side of the tyre surface, turn the steering
wheel to full lock.
All wheels must have avalve cap to protec tthe
valve against dirt and moisture. Do not fit any-
thing ontot he valve other than the standard
valve cap or avalve cap approved by Mercedes-
Benz for your vehicle. Do not fit any other valve caps or systems, e.g. tyre pressure monitors.
You should regularly check the pressure of all
your tyres including the spare wheel, particu-
larly prior to long trips. Adjust the tyre pressure as necessary (Y page 238).
The service life of atyre depends on various fac-
tors, including the following:

WARNING
Underinf lated or overinflated tyres pose the
following risks:
R the tyres may burst, especially as the load
and vehicl espee dincrease.
R the tyres may weare xcessively and/or
unevenly, which may greatly impair tyre
traction.
R the driving characteristics, as wellass teer-
ing and braking, may be greatly impaired.
There is arisk of an accident.
Observe the recommende dtyre pressure and
check the tyre pressure of all the tyres includ-
ing the spar ewheel:
R at least every two weeks
R when the loadc hanges
R before embarking on alonger journey
R for changed operating conditions, e.g. off-
road driving
If necessary, correct the tyre pressure. G
WARNING
If you fit unsuitabl eaccessories onto tyre
valves, the tyre valve smay be overloadeda nd
malfunction, which can caus etyre pressure
loss. Due to their design, retrofitted tyre pres-
sure monitors keep the tyre valve open. This
can alsor esult in tyre pressure loss. There is a
risk of accident.
Only screw standar dvalve caps or valve caps
specifically provided by Mercedes-Benz for
yourv ehicleonto the tyre valve. G
WARNING
If the tyre pressure drops repeatedly ,the
wheel, valve or tyre may be damaged. Tyre
pressure that is too low may result in atyre
blow-out. There is arisk of accident. 238
Tyre pressureWheels and tyres
For further information on displaying this mes-
sage, refe rtothe "Checking the tyre pressure
electronically" section (Y page 240).
Important safety notes It is the driver's responsibility to set the tyre
pressure to the recommended cold tyre pres-
sure suitable for the operating situation
(Y page 238). Note that the correc ttyre pres-
sure for the current operating situation must
first be learnt by the tyre pressure monitor. If a
substantial loss of pressure occurs, the warning threshold for the warning message is aligned to
the learnt reference values. Restart the tyre
pressure monitor after adjusting to the cold tyre pressure (Y page 241). The current pressures
are saved as new reference values. This ensures that awarning message appears only 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 238).
The tyre pressure monitor is not abletow arn
you of asudden loss of pressure, e.g. if the tyre
is penetrated by aforeign object. In this event,
bring the vehicle to ahalt by braking carefully.
Avoid abrupt steering manoeuvres.
The tyre pressure monitor has ayellow h
warning lamp on the instrument cluster for indi-
cating apressure loss or malfunction. Depend-
ing on how the warning lamp flashe sorlights up,
at yre pressure that is too low or amalfunction in
the tyre pressure monitor is indicated:
R if the h warning lamp is lit continuously,
the tyre pressure on one or more tyres is sig-
nificantly too low. The tyre pressure monitor
is not malfunctioning.
R if the h warning lamp flashe sfor around a
minute and then remains lit constantly, the
tyre pressure monitor is malfunctioning.
In addition to the hwarning lamp,am essage
appears in the multifunction display. Observe
the information on display messages
(Y page 150).
It may take up to ten minutes for amalfunction
of the tyre pressure monitor to be indicated .A
malfunction willbei ndicated by thehtyre
pressure warning lamp flashing for approx-
imatel yone minute and then remaining lit. When
the faulth as been rectified, the htyre pres-
sure warning lamp goes out after driving for a
few minutes. The tyre pressure values indicated by the on-
board computer may differ from those meas-
ured at
afilling station using apressure gauge.
The tyre pressures shown by the on-board com-
puter refer to those measured at sea level. At
high altitudes, the tyre pressure values indica-
ted by apressure 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 interferenc efrom radio transmit-
ting equipment (e.g. cordless headphones, two- way radios) that may be being operated in or
near the vehicle.

(Y page2 43). The wear patterns on the front and rear tyres
diffe
rdepending on the operating conditions.
Interchange the wheels before aclear wear pat-
tern has formed on the tyres. Frontt yres typi-
cally wear more on the shoulders, while rear
tyres wear more in the centre.
On vehicles that have front and rear wheels of
the same size, you can interchange the wheels
every 5,000 to 10,00 0kmd epending on the
degree of tyre wear. Ensure that the direction of
rotation is maintained.
Clean the contact surfaces of the wheel and the
brake disc thoroughly every time awheel is
