Preparing the vehicle
Park the vehicle in a safe distance from
moving traffic on a hard, flat surface
when possible.

Turn on the hazard warning flasher
(page 142).

Turn the steering wheel so that the
front wheels are in a straight-ahead
position.

Set the parking brake (
page 57).

Set the automatic transmission to park
positionP (
page 187).

Turn off the engine (
page 39).

Remove the SmartKey from the starter
switch.
Vehicles with KEYLESS-GO*:
Turn off the engine by pressing the
KEYLESS-GO* button once
(page 67).

Open the driver’s door (this puts
the starter switch in position0,
same as with the SmartKey re-
moved from the starter switch). The
driver’s door then can be closed
again.

Have any passenger exit the vehicle at
a safe distance from the roadway.
Warning!
G
The dimensions of the spare wheel
(Minispare wheel or collapsible tire) are dif-
ferent from those of the road wheels. As a
result, the vehicle handling characteristics
change when driving with a spare wheel
mounted. Adapt your driving style accord-
ingly.
The spare wheel is for temporary use only.
When driving with a spare wheel mounted,
ensure proper tire pressure and do not ex-
ceed a vehicle speed of 50 mph (80 km/h).
Drive to the nearest Mercedes-Benz Light
Truck Center as soon as possible to have the
spare wheel replaced with a regular road
wheel.
Never operate the vehicle with more than
one spare wheel mounted.
Do not switch off the ESP
® when a
Minispare wheel is mounted.
Warning!
G
Vehicles with air suspension package*:
Do not open or close any doors or the
tailgate while mounting a spare wheel. The
vehicle could rise or lower to a previously
selected level. You or others could be
injured as a result.
i
Open door only when conditions are safe to
do so.

Towing the vehicle
Warning!
G
If circumstances require towing the vehicle
with all wheels on the ground, always tow
with a tow bar if:

the engine will not run


there is a malfunction in the power
supply or in the vehicle’s electrical sys-
tem
Prior to towing the vehicle with all wheels on
the ground, make sure the starter switch is
in position2 (
page 40).
Warning!
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
vehicle. Adapt your driving accordingly.
i
To signal turns while being towed with
hazard warning flasher in use, set the starter
switch to position2 and activate combination
switch for left or right turn signal in usual manner
– only the selected turn signal will operate.
Upon canceling the turn signal, the hazard
warning flasher will operate again.
i
If the battery is disconnected or discharged,
the automatic transmission will remain locked in
positionP and the SmartKey will not turn in the
starter switch. For more information, see “Bat-
tery” (page 507) and “Jump starting”
(
page 515).
!
When towing the vehicle with all wheels on
the ground, note the following:
With the automatic central locking activated and
the ignition in position2 (
page 40), the vehicle
doors lock if the left front wheel is turning at a
speed of approximately 9 mph (15 km/h) or
above.
To prevent the vehicle doors from locking,
deactivate the automatic central locking
(
page 126).
Towing of the vehicle should only be done using
the towing eye bolt. Never attach tow cable, tow
rope or tow rod to vehicle chassis, frame or sus-
pension parts.
