179 Operation
Driving instructions
Driving instructions
Drive sensibly – save fuel
Fuel consumption, to a great extent, de-
pends on driving habits and operating con-
ditions.
To save fuel you should:

Keep tires at the recommended infla-
tion pressures


Remove unnecessary loads


Allow engine to warm up under low
load use


Avoid frequent acceleration and decel-
eration


Have all maintenance work performed
at regular intervals by an authorized
Mercedes-Benz Light Truck Center
Fuel consumption is also increased by driv-
ing in cold weather, in stop-and-go traffic,
on short trips and in hilly country.
Drinking and driving
PedalsPower assistance
Warning!
G
Drinking and driving and/or taking drugs
and driving are a very dangerous combina-
tion. Even a small amount of alcohol or
drugs can affect your reflexes, perceptions
and judgement.
The possibility of a serious or even fatal ac-
cident is sharply increased when you drink
or take drugs and drive.
Don’t drink or take drugs and drive or allow
anyone to drive after drinking or taking
drugs.
Warning!
G
Keep driver’s foot area clear at all times. Ob-
jects stored in this area may impair pedal
movement.Warning!
G
When the engine is not running, there is no
power assistance for the steering system. In
this case, it is important to keep in mind that
a considerably higher degree of effort is nec-
essary to steer the vehicle.

220 OperationVehicle careOrnamental moldings
For regular cleaning and care of very dirty
chrome-plated parts, use a chrome clean-
er.
Headlamps, tail lamps, turn signal
lenses
Use a mild car wash detergent, such as
Mercedes-Benz approved Car Shampoo,
with plenty of water.
To prevent scratches, never apply strong
force and use only a soft, non-scratchy
cloth when cleaning the lenses. Do not at-
tempt to wipe dirty lenses with a dry cloth
or sponge.Cleaning the Parktronic* system

1Parktronic system sensor
Use a mild car wash detergent, such as
Mercedes-Benz approved Car Shampoo,
with plenty of water to clean the sensor1.
When using a steam cleaner or power
washer, aim nozzle only briefly from a min-
imum distance of 4 in. (10 cm) at
sensors1.
To prevent scratches, never apply strong
force and use only a soft, non-scratchy
cloth when cleaning the sensor. Do not at-
tempt to wipe dirty sensors with a dry cloth
or sponge.Wiper blades
Clean the wiper blade inserts with a clean
cloth and detergent solution.
Window cleaning
Use a window cleaning solution on all glass
surfaces. An automotive glass cleaner is
recommended.
iFor safety reasons, remove key from
steering lock before cleaning the wiper
blades, otherwise the wiper motor can
suddenly turn on and cause injury.iFor safety reasons, switch off wipers
and remove key from steering lock be-

267 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 key in steering lock 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 76),
tow-away alarm (
page 80) and the
automatic central locking (
page 89).
!When towing the vehicle with all wheels
on the ground, the selector lever must
be in position N and the key m us t be in
steering lock position 2.
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 the front
axle raised (observe instructions re-
garding flexible drive shaft), the engine
must be shut off (key in steering lock
position1). Otherwise, the 4-ETS may
become engaged which may cause loss
of towing control.
!To be certain to avoid additional dam-
age to the vehicle powertrain, however
you should observe the following:

With damage to the front axle

raise front axle


remove flexible drive shaft be-
tween rear axle and transfer
case


With damage to the rear axle

raise rear axle


tow vehicle with wheel lift or
dolly placed under front wheels


With damage to the transfer case

remove flexible drive shaft to
the drive axles
Always install new self-locking nuts
when reinstalling flexible drive shaft.

268 Practical hintsTowing the vehicleWarning!
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 sup-
ply or in the vehicle’s electrical system
Prior to towing the vehicle with all wheels on
the ground, make certain that the key is in
steering lock position2.
If the key is left in steering lock 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, remove
key from steering lock and reinsert.
Warning!
G
With the engine not running, there is no
power assistance for the braking and steer-
ing systems. In this case, it is important to
keep in mind that a considerably higher de-
gree of effort is necessary to brake and
steer the vehicle. Adapt your driving accord-
ingly.iTo signal turns while being towed with
hazard warning flasher in use, turn key
in steering lock to position2 and acti-
vate combination switch for left or right
turn signal in usual manner – only the
selected turn signal will operate.
Upon canceling the turn signal, the haz-
ard warning flasher will operate again.iThe vehicle cannot be started via
tow-start.
!When towing the vehicle with all wheels
on the ground, note the following:
With the automatic central locking acti-
vated and the key in steering lock
position2, the vehicle doors lock if the
left front wheel is 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 89).
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.
