a safe distance from the roadway.

Remove the vehicle tool kit
(page 283) and the jack
(page 284).

Remove the spare wheel from the
spare wheel mounting bracket
(page 285).Information on spare wheel
When you replace the vehicle’s tires, you
can use the spare wheel as a regular wheel
if:


it is not more than six years old


rim and tire are the same model as the
regular wheels
Warning!
G
For your safety, remove spare wheel from
the spare wheel mounting bracket before
undertaking any further steps.
Warning!
G
If the spare tire is more than six years old or
is not the same model as the regular tires,
have the spare tire replaced with a new tire
at the nearest Mercedes-Benz Light Truck
Center.
Never operate the vehicle with more than
one spare tire.
Warning!
G
G 55 AMG only
Vehicles with different tire dimensions on
the front and rear axle: rim and tire size of
spare wheel and normal wheel differ. Han-
dling will be adversely affected when the
spare wheel is used.
Do not exceed the maximum speed of
50 mph (80 km/h).

307 Practical hints

Mounting the spare wheel
Prepare the vehicle (
page 306).
Lifting the vehicle

Prevent the vehicle from rolling away
by blocking wheels with wheel chocks
(not included) or other sizable objects.
When changing wheel on a level surface:

Place one chock in front of and one be-
hind the wheel that is diagonally oppo-
site to the wheel being changed.
When changing wheel on a hill:

Place chocks on the downhill side
blocking both wheels of the other axle.
Wheel wrench
On wheel to be changed, loosen but do
not yet remove the wheel bolts (ap-
proximately one full turn with wrench).
Warning!
G
The jack is designed exclusively for jacking
up the vehicle under the axle housing. To
help avoid personal injury, use the jack only
to lift the vehicle during a wheel change.
Never get beneath the vehicle while it is sup-
ported by the jack. Keep hands and feet
away from the area under the lifted vehicle.
Always firmly set parking brake and block
wheels before raising vehicle with jack.
Do not disengage parking brake while the
vehicle is raised. Be certain that the jack is
always vertical (plumb line) when in use, es-
pecially on hills. Always try to use the jack
on level surface. Make sure the jack is posi-
tioned correctly under the axle housing. Al-
ways lower the vehicle onto sufficient
capacity jackstands before working under
the vehicle.
If the vehicle is not raised as described, it
could slip off the jack as a result of vibra-
tions (e.g. opening or closing a door or the
tailgate).

312 Practical hintsBatteryDisconnecting the battery
Turn off all electrical consumers.

Disconnect the battery negative lead.

Remove the cover from the positive ter-
minal.

Disconnect the battery positive lead.

Remove the breather hose from the
battery.
Reconnecting the battery
Turn off all electrical consumers.

Connect the positive lead and fasten its
cover.

Connect the negative lead.

Install the breather hose.
!Never loosen or detach battery termi-
nal clamps while the engine is running
or the SmartKey is in the starter switch.
Otherwise the alternator and other
electronic components could be se-
verely damaged.
iWith a disconnected battery

you will no longer be able to turn
the SmartKey in the starter switch


the gear selector lever will remain
locked in positionP
!Never invert the terminal connections.!The battery, its filler caps and the vent
tube must always be securely installed
when the vehicle is in operation.
iThe following procedures must be car-
ried out following any interruption of
battery power (e.g. due to reconnec-
tion):

Set the clock (see COMAND opera-
tor’s manual).


Resynchronize the front seat head
restraints and seat adjustment fore,
aft (
page 95).


Synchronize the ESP (
page 263).

315 Practical hints
Towing the vehicle
Towing the vehicle
Mercedes-Benz recommends that the vehi-
cle be transported with all wheels off the
ground using flatbed or appropriate wheel
lift/dolly equipment. This method is pref-
erable to other types of towing.
When circumstances do not permit the
recommended towing methods, the vehi-
cle may be towed with all wheels on the ground only so far as necessary to have the
vehicle moved to a safe location where the
recommended towing methods can be em-
ployed.
!Use flatbed or wheel lift/dolly equip-
ment, with SmartKey in starter switch
turned to position0.
Do not tow with sling-type equipment.
Towing with sling-type equipment over
bumpy roads will damage radiator and
supports.
To prevent damage during transport,
do not tie down vehicle by its chassis or
suspension parts. Use the towing eyes.
Switch off the ESP (
page 79),
tow-away alarm (
page 83) and the
automatic central locking
(
page 133).
!When towing the vehicle with all wheels
on the ground, the gear selector lever
must be in position N and the Smart-
Key must be in starter switch
position2.
When towing the vehicle with all wheels
on the ground, the vehicle may be
towed only for distances up to 30 miles
(50 km) and at a speed not to exceed
30 mph (50 km/h).
If the vehicle is towed with one axle
raised (observe instructions regarding
flexible drive shaft and propeller
shafts), the engine must be shut off
(SmartKey in starter switch position1).
Otherwise, the 4-ETS may become en-
gaged which may cause loss of towing
control.
!Do not tow-start the vehicle.Warning!
G
Prior to towing the vehicle with all wheels on
the ground, make certain that the SmartKey
is in starter switch position2.
If the SmartKey is left in the starter switch
position0 for an extended period of time, it
can no longer be turned in the switch. In this
case, the steering is locked. To unlock, re-
move SmartKey from starter switch and re-
insert.
Always tow with a tow bar if:

the engine will not run


there is a malfunction in the power sup-
ply or in the vehicle’s electrical system
as that will be necessary to adequately con-
trol the towed vehicle.

316 Practical hintsTowing the vehicleWarning!
G
With the engine not running, there is no
power assistance for the brake and steering
systems. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the ve-
hicle. Adapt your driving accordingly.iThe gear selector lever will remain
locked in positionP and the SmartKey
will not turn in the starter switch if the
battery is disconnected or discharged.
See notes on the battery (
page 311)
or on jump starting (
page 313).
Manually unlocking transmission gear
selector lever (
page 290).
iTo signal turns while being towed with
hazard warning flasher in use, turn
SmartKey in starter switch to
position2 and activate combination
switch for left or right turn signal in usu-
al manner – only the selected turn sig-
nal will operate.
Upon canceling the turn signal, the haz-
ard warning flasher will operate again.
!When towing the vehicle with all wheels
on the ground, note the following:
With the automatic central locking acti-
vated and the SmartKey in starter
switch position2, the vehicle doors
lock if the wheels are turning at vehicle
speeds of approx. 9 mph (15 km/h) or
more.
To prevent the vehicle doors from lock-
ing, deactivate the automatic central
locking (
page 133).
Towing of the vehicle should only be
done using the towing eye. Never at-
tach tow cable, tow rope or tow rod to
vehicle chassis, frame or suspension
parts.

317 Practical hints
Towing the vehicle
Transporting the vehicle
When transporting the vehicle, you can use
the towing eyes for pulling the vehicle onto
a trailer or transporter. 
Move the gear selector lever to posi-
tion N.

Shift the transfer case to neutral posi-
tion N.

To avoid damaging the vehicle, it
should only be tied down on the
wheels / wheel rims, not on chassis
components such as the transverse
link or trailing arm.Towing the vehicle - various problem
scenarios
Comply with all towing information
(page 315).
In case of engine damage, transmission
damage or malfunctions in electrical
equipment

Move the gear selector lever to posi-
tion N.

Shift the transfer case to neutral posi-
tion N.In case of transfer case damage or for
towing vehicle distances exceeding
30 miles (50 km)
The propeller shafts to the drive axles must
be removed.
In case of front axle damage
Raise the front axle when towing. The pro-
peller shaft between the rear axle and the
transfer case must be removed.
In case of rear axle damage
When the rear axle is raised, the vehicle
can only be towed with a wheel lift or a dol-
ly placed under its front wheels.!When removing drive shaft, place M10
nuts on bolts as distance sleeves and
tighten using M8 nuts.
Always install new self-locking nuts
when reinstalling the drive shaft.
