2012 MERCEDES-BENZ G-CLASS SUV ignition

Towing the vehicle with both axles on
the ground
It is important tha tyou observe the safety
instructions when towing away your vehicle
(Y page 315).
X Switch on the hazard warning lamps
(Y page 109).
i In order to signal a change of direction
when towing the vehicle with the hazard
warning lamps switched on, use the com-
bination switch as usual.Int his case, only
the turn signals for the desired direction
flash. When you reset the combination
switch, the hazard warning lamps start
flashing again.
X Turn the key to position 2in the ignition
lock (Y page 143).
X When the vehicle is stationary, depress the
brake pedal and keep it depressed.
X Shift the transfer case to neu-
tral(Y page 203).
X Shift the automatic transmission to posi-
tion N.
X Release the brake pedal.
X Release the parking brake (Y page 164).
i The transmission can only change gear
when the battery has sufficient charge.
If you cannot move the selector lever to N,
you must remove the propeller shafts to the
driven axles. Transporting the vehicle
! Only lash the vehicle down by the wheels
or wheel rims, not by parts of the vehicle
such as axle or steering components. Oth-
erwise, the vehicle could be damaged.
Use the towing eyes to pull the vehicle if it
needs to be transported on a trailer or trans-
porter (Y page 316).
X Apply the parking brake.
X Turn the key to position 2in the ignition
lock (Y page 143). X
Move the selector lever to N.
X Shift the transfer case to neu-
tral(Y page 203).
X Secure the towing cable to the towing eyes
(Y page 316).
X Make sure that the vehicle cannot roll
away.
X Release the parking brake.
X Load the vehicle onto the transporter.
As soon as the vehicle is loaded:
X Apply the parking brake.
X Shift the automatic transmission to posi-
tion P.
X Turn the key to position 0in the ignition
lock (Y page 143) and remove it.
X Secure the vehicle. Recovering
avehicle that has become
stuck
! When recovering a trapped vehicle, do not
jerk the vehicle or pull it at an angle. If the
tractive power is too high, the vehicles
could be damaged.
If the drive wheels get trapped on loose or
muddy ground, recover th evehicle with the
utmost care, especially so if the vehicle is
laden.
Never attempt to recover a vehicle with a
trailer attached.
Pull out the vehicle backwards, if possible,
using the tracks it made when it became
stuck. Towing in the event of malfunctions
General notes !
If you are removing the propeller shaft,
use M10 nuts as spacers on the M8 bolts
and secure them with M8 nuts.
New self-locking nuts must be used when
the propeller shafts are refitted. Towing and tow-starting

Observe the safety notes as you do so
(Y page 315).
i Consult a Mercedes-Benz Service Centre.
Engine damage, gear damage or electri-
cal faults X
Move the selector lever to posi-
tion N(Y page 149).
X Shift the transfer case to neu-
tral (Ypage 203).
In the event of damage to the transfer
case Have the propellers
hafts between the axles
and the transfer case removed.
In the event of damage to the front axle Have the propeller shaft between the rear
axle and the transfer case removed.
Have the vehicle towed with the front axle
raised.
In the event of damage to the rear axle
Have the propeller shaft between the front
axle and the transfer case removed.
Then, have the vehicle towed with the rear
axle raised and with wheel rollers under the
front axle.
Electrical fuses
Important safety notes
G
WARNING
Only use fuses that have been approved for
Mercedes-Ben zvehicles and which have the
correct fuse rating for the systems con-
cerned. Do not attempt to repair or bridge
faulty fuses. Using fuses which have not been
approved or attempting to repair or bridge
faulty fuses could cause the fuse to be over-
loaded and result in a fire. Have the cause traced and rectified at a qualified specialist
workshop.
! 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 serve to disconnect
faulty circuits. If afuse blows, all the compo-
nents on the circuit and their functions will
fail.
Blown fuses must be replace dwith 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
X Park the vehicle and apply the parking
brake.
X Switch off all electrical consumers.
X Remove the key from the ignition lock.
All indicator lamps in the instrumen tcluster
must be off.
The fuses are located in various fuse boxes:
R Main fuse box on the driver's side of the
dashboard
R Fuse box in the front-passenger footwell
R Fuse box in the transmission tunnel
R Fuse box in the battery case
The fuse allocation char tand the spare fuses
are in the main fuse bo xonthe dashboard
(Y page 319).
You will find the fuse removal device in the
vehicle tool kit (Y page 306).318

ured at a filling station with 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 val-
ues indicated by a pressur
egauge are higher
than those shown by the on-board computer.
In this case, do no treduce 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.
Checking tyre pressure electronically X
Make sure that the key is in position 2
(Y page 143)in the ignition lock.
X Press the =or; button on the steer-
ing wheel to select the Serv. menu.
X Press the 9or: button to select
Tyre pressure .
X Press the abutton.
The curren ttyre pressur efor each wheel
will be displayed in the multifunction dis-
play.
If the vehicle has been parked for over
20 minutes, the message Tyre pressureswill be displayed after a few
minutes of driving 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 Tyrepressure monitor active display mes-
sage is shown instead of the tyre pressure
display .The tyre pressures are already being
monitored.
i If a spare wheel is fitted, the system may
continue to show the tyre pressure 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
tyre is fitted is not the same as the spare
tyre's current tyre pressure. Warning messages of the tyre pressure
monitor If the tyre pressure monitor detects a signifi-
cant pressure loss on one or more tyres, a
warning message is shown in the multifunc-
tion display.
Awarning tone also sounds and
the tyre pressure warning lamp lights up in
the instrument cluster.
Each tyre that is affected by a significant loss
of pressure is highlighted in the pressure dis-
play.
X If the Please correct tyre pres‐ surePlease correct tyre pressure
message appears in the multifunction dis-
play, check the tyre pressure on all four
wheels and correct it if necessary.
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.
Restarting the tyre pressure monitor When you restar
tthe 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 referencev alues after you
have changed the tyre pressure .However,
you can also define reference values man-
ually as described here.
X Use 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 325).
X Make sure that the key is in position 2
(Y page 143) in the ignition lock.
X Press the =or; button on the steer-
ing wheel to select the Serv. menu.328
