X
When the vehicle is stationary, depress the
brake pedal and keep it depressed.
X Shift the transfer case to position Neutral
(Y page 125).
X Shift the automatic transmission to position
N.
X Leave the key in position 2in the ignition
lock.
X Release the brake pedal.
X Release the parking brake.
X Switc hont he hazard warning lamps
(Y page 76).
In order to signal achange of direction when
towing the vehicle with the hazard warning
lamps switched on, use the combination switch
as usual. In this case, only the turn signals for
the desired direction flash. When you reset the
combination switch, the hazard warning lamps
start flashing again.
i The automatic transmission can only
change gear when the batter yhas sufficient
charge.
If you cannot shift the automatic transmission
to position N,the propeller shafts to the
driven axles must be removed. Transporting thev
ehicle !
Whe
nthe vehicle is loadedf or transport, the
front and rear axles must be stationary and on the same transportation vehicle. Positioning
over the connection point of the transport
vehicle is not permitted. The drive train may
otherwise be damaged.
! You may only secure the vehicle by the
wheels, not by parts of the vehicle such as
axle or steering components. Otherwise, the
vehicle could be damaged. The towing eye or trailer tow hitch can be used
to pull the vehicle onto
atrailer or transporter if
you wish to transport it.
X Turn the key to position 2in the ignition
lock.
X Shift the transfer case to position Neutral
(Y page 125).
X Shift the automatic transmission to position
N.
As soon as the vehicle is loaded:
X Apply the parking brake.
X Shift the automatic transmission to position
P.
X Turn the key to position uin the ignition lock
and remove it.
X Secure the vehicle. Recovering

M10 nuts as spacers on the M8 bolts and
secure them with M8 nuts.
New self-locking nuts must be used when the propellers hafts are refitted.

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

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.

If the Rectify tyre pressure
Rectify tyre pressure message
appears in the multifunction display, the tyre
pressure in at least one tyre is too low. The
tyre pressure must be corrected when the
opportunity arises.
R If the Check Check tyre(s)
tyre(s) message appears in the
multifunction display, the tyre pressure in at
least one tyre has droppe dsignificantly. The
tyres must be checked.
R If the Warning tyre defect Warning tyre defect message
appears in the multifunction display, the tyre
pressure in at least one tyre has droppe dsud-
denly.T he tyres must be checked.
Observe the instructions and safety notes in the display messages in the "Tyres" section
(Y page 150).
If the positio nofthe wheelsont he vehicle is
changed, the tyre pressures may be displayedin the wrong positions for ashort time. After afew
minutes of driving, this is rectified and the tyre
pressures are displayedint he correct positions.
Restarting the tyre pressure monitor When you restart the tyre pressure monitor, all
existing warning messages are deleted and the
h
warning lamp goes out. The monitor uses
the currently set tyre pressures as the reference valuesf or 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 set
reference values manually as described here.
The tyre pressure monitor then monitors the
new tyre pressure values.
X Use the table on the inside of the fuel filler flap
to ensure that the tyre pressure is set cor-
rectly in all four tyres for the curren toperating
conditions.
