Electrical fuses
Important safety notes
GWARNING
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.
! Only use fuses that have been approved
for Mercedes-Benz vehicles and which
have the correct fuse rating for the system
concerned. Only use fuses marked with an
"S". Components or systems could other-
wise be damaged.
The fuses in your vehicle serve to disconnect
faulty circuits. If a fuse blows, all the compo-
nents on 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.
If the newly inserted fuse also blows, have the
cause traced and rectified at a qualified spe-
cialist workshop, e.g. a Mercedes-Benz
Service Centre.
Before replacing a fuse
XSecure the vehicle against rolling away
( Y page 162).XSwitch off all electrical consumers.XTurn the key to position 0 in the ignition
lock and remove it ( Y page 145). All indi-
cator lamps in the instrument cluster must
be off.
The fuses are located in various fuse boxes:
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 front-passenger footwell
The fuse allocation chart is on the fuse box in
the front-passenger footwell ( Y page 313).

GWARNING
When the bonnet is open, and the windscreen
wipers are set in motion, you can be injured
by the wiper linkage. There is a risk of injury.
Always switch off the windscreen wipers and
the ignition before opening the bonnet.
! 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.

iThe tyre pressure values given for low
loads are minimum values which offer you
good ride comfort characteristics.
However, you can also use the values given
for higher loads. These are permissible and
will not adversely affect the running of the
vehicle.
Tyre pressure loss warning system
General notes
While the vehicle is in motion, the tyre pres-
sure loss warning system monitors the set
tyre pressure using the rotational speed of
the wheels. This enables the system to detect
significant pressure loss in a tyre. If the speed
of rotation of a wheel changes as a result of
a loss of pressure, a corresponding warning
message will appear in the multifunction dis-
play.
You can recognise the tyre pressure loss
warning by the Run Flat Indicator
active Restart with OK message which
appears in the Service menu of the multi-
function display. Further information on the
message display can be found under "Restart-
ing the tyre pressure loss warning system"
( Y page 321).
Important safety notes
The tyre pressure warning system does not
warn you of an incorrectly set tyre pressure.
Observe the notes on the recommended tyre
pressure ( Y page 319).
The tyre pressure loss warning does not
replace the need to regularly check the tyre
pressures. An even loss of pressure on sev-
eral tyres at the same time cannot be detec-
ted by the tyre pressure loss warning system.
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 function of the tyre pressure loss warning
system is limited or delayed if:
R snow chains are fitted to your vehicle's
tyres.
R road conditions are wintry.
R you are driving on sand or gravel.
R you adopt a very sporty driving style (cor-
nering at high speeds or driving with high
rates of acceleration).
R you are towing a very heavy or large trailer.
R you are driving with a heavy load (in the
vehicle or on the roof).
Restarting the tyre pressure loss warn-
ing system
Restart the tyre pressure loss warning system
if you have:
R changed the tyre pressure
R changed the wheels or tyres
R fitted new wheels or tyres
XBefore restarting, make sure that the tyre
pressures are set properly on all four tyres
for the respective operating conditions.
The recommended tyre pressures can be
found in the table on the fuel filler flap.
The tyre pressure loss warning system can
only give reliable warnings if you have set
the correct tyre pressure. If an incorrect
tyre pressure is set, these incorrect values
will be monitored.XObserve the notes in the section on tyre
pressures ( Y page 319).XMake sure that the key is in position 2 in
the ignition lock ( Y page 145).XPress = or ; on the steering wheel

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.

The current tyre pressure for each wheel
will be displayed in the multifunction dis-
play.
If the vehicle has been parked for over
20 minutes, the Tyre pressures will be
displayed after a few minutes of
driving message appears.
After a teach-in period, the tyre pressure
monitor automatically recognises new
wheels or new sensors. As long as a clear
allocation of the tyre pressure values to the
individual wheels is not possible, the Tyre
pressure monitor active display mes-
sage is shown instead of the tyre pressure
display. The tyre pressures are already being
monitored.
i If an emergency spare wheel is fitted, the
system may continue to show the tyre pres-
sure of the wheel that has been removed
for a few minutes. If this occurs, note that
the value displayed for the position where
the spare wheel is fitted is not the same as
the current tyre pressure of the emergency
spare wheel.
Warning messages of the tyre pressure
monitor
If the tyre pressure monitor detects a pres-
sure loss in one or more tyres, a warning mes-
sage is shown in the multifunction display and
the yellow tyre pressure monitor warning light
comes on.
R If the Please correct tyre pressure
message appears in the multifunction dis-
play, the tyre pressure in at least one tyre
is too low and must be corrected at the next
opportunity.
R If the Tyre pressure Check tyre(s)
message appears in the multifunction dis-
play, the tyre pressure in one or more tyres
has dropped significantly and the tyres
must be checked.
R If the Tyre pressure Caution, tyre
defect message appears in the multifunc-
tion display, the tyre pressure in one or
more tyres has dropped suddenly and the
tyres must be checked.
Observe the instructions and safety notes in
the display messages in the "Tyres" section
( Y page 248).
i If the wheel positions on the vehicle are
interchanged, the tyre pressures may be
displayed for the wrong positions for a
short time. This is rectified after a few
minutes of driving and the tyre pressures
are displayed for the correct positions.
Tyre pressure323Wheels and tyresZ

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.
XUse the table on the inside of the fuel filler
flap to ensure that the tyre pressure is set
correctly in all four tyres for the current
operating conditions.
Also observe the notes in the section on
tyre pressures ( Y page 319).XMake sure that the key is in position 2 in
the ignition lock.XPress the = or ; button on the steer-
ing wheel to select the Service menu.XPress the 9 or : button to select

rent tyre pressure for the individual tyres or
the Tyre pressures will be dis‐
played after a few minutes of driv‐
ing message.XPress the : button.
The Use current pressures as new
reference values message appears in
the multifunction display.
If you wish to confirm the restart:
XPress the a button.
The Tyre press. monitor restarted
message appears in the multifunction dis-
play.
After you have driven for a few minutes, the
system checks whether the current tyre
pressures are within the specified range.The new tyre pressures are then accepted
as reference values and monitored.
If you wish to cancel the restart:
XPress the % button.
The tyre pressure values stored at the last
restart will continue to be monitored.
Changing a wheel
Flat tyre
You can find information on what to do in the
event of flat tyre in the "Flat tyre" section
( Y page 298). Information on driving with
MOExtended tyres in the event of a flat tyre
can be found under "Breakdown assistance"
( Y page 298).
Vehicles with an emergency spare
wheel: in the event of a flat tyre, the emer-
gency spare wheel is fitted according to the
description under "Fitting a wheel"
( Y page 325).
Interchanging the wheels
GWARNING
Interchanging the front and rear wheels may
severely impair the driving characteristics if
the wheels or tyres have different dimensions.
The wheel brakes or suspension components
may also be damaged. There is a risk of acci-
dent.
Interchange front and rear wheels only if the
wheels and tyres are of the same dimensions.
! On vehicles fitted with a tyre pressure
monitor, electronic components are loca-
ted in the wheel.
Tyre-fitting tools should not be applied in
the area of the valve, as this could damage
the electronic components.
Only have tyres changed at a qualified spe-
cialist workshop.
324Changing a wheelWheels and tyres

Interchanging the front and rear wheels of
differing dimensions can render the general
operating permit invalid.
Always pay attention to the instructions and
safety notes when changing a wheel
( Y page 324).
The wear patterns on the front and rear tyres
differ, depending on the operating conditions.
Interchange the wheels before a clear wear
pattern has formed on the tyres. Front tyres
typically wear more on the shoulders and the
rear tyres in the centre.
On vehicles that have the same size front and
rear wheels, you can interchange the wheels
every 5,000 to 10,000 km depending on the
degree of tyre wear. Ensure the direction of
rotation is maintained.
Clean the contact surfaces of the wheel and
the brake disc thoroughly every time a wheel
is interchanged. Check the tyre pressure and,
if necessary, restart the tyre pressure loss
warning system or the tyre pressure monitor.
Direction of rotation
Tyres with a specified direction of rotation
have additional benefits, e.g. if there is a risk
of aquaplaning. You will only gain these ben-
efits if the correct direction of rotation is
observed.
An arrow on the sidewall of the tyre indicates
its correct direction of rotation.
Storing wheels
Store wheels that are not being used in a cool,
dry and preferably dark place. Protect the
tyres against oil, grease, petrol and diesel.
Cleaning the wheels
GWARNING
The water jet of circular-jet nozzles (dirt grind-
ers) can cause damage not visible from the
outside to tyres or chassis components. Com-
ponents damaged in this way can unexpect-
edly fail. There is a risk of an accident.
Do not use high-pressure cleaners with circu-
lar-jet nozzles to clean the vehicle. Have dam-
aged tyres or chassis components replaced
immediately.
