ESP
ESP
NOT AVAILABLE
The charging voltage has fallen below
10 volts and the ESP has switched off.

When the voltage is above this value
again, the ESP is operational again.

If necessary, have the generator (alter-
nator) and battery checked.
The ESP is deactivated because of a mal-
function or interrupted power supply. The
ABS and BAS might not be operational.
The system must be resynchronized.

Synchronize the ESP. With vehicle sta-
tionary and the engine running, turn
the steering wheel completely to the
left and then to the right to synchro-
nize the ESP.
If the ESP message does not go out:

Continue driving with added caution.

Visit an authorized Mercedes-Benz
Light Truck Center as soon as possi-
ble.
Failure to follow these instructions in-
creases the risk of accident.
!When synchronizing the ESP, make
sure you can turn the steering wheel in
both directions as far as it will go with-
out the wheels hitting any objects, e.g.
a road curb.

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

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).

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.
