44 Getting startedDriving
Make sure that the selector lever is set
toP.

Do not depress accelerator.

Turn key in the starter switch to
position3 and hold until the engine
starts (
page 33).

Depress the brake pedal.
The selector lever lock is released.
For information on turning off the engine,
see “Turning off engine” (
page 51).Starting difficulties
If the engine does not start as described,
carry out the following steps:

Turn key in starter switch to position0
and repeat starting procedure.

Remember that extended starting at-
tempts can drain the battery.

Get a jump start (
page 297).
If the engine does not start after several
starting attempts, there could be a mal-
function in the engine electronics or in the
fuel supply system.

Notify an authorized Mercedes-Benz
Light Truck Center.Parking brake
1Lever
2Button
iYou can also use the “touch-start”
function. Turn the key to position3 and
release it again immediately. The en-
gine then starts automatically.
Warning!
G
When leaving the vehicle, always remove the
key from the starter switch, and lock the ve-
hicle.
Do not leave children unattended in the ve-
hicle, or with access to an unlocked vehicle.
Children could release the parking brake,
which could result in an accident and/or se-
rious personal injury.

45 Getting started
Driving

Release the parking brake by lifting
lever1 up slightly, pressing button2
on the lever and moving lever1 down
to the stop.
The indicator lamp
;
(USA only) or
3
(Canada only) in the instrument
cluster goes out.
Driving

Depress the brake pedal.
The selector lever lock is released.

Move selector lever to positionD orR.

Release the brake pedal.

Carefully depress the accelerator.
Once the vehicle is in motion, the auto-
matic central locking system engages
and the locking knobs drop down.After a cold start, the automatic transmis-
sion engages at a higher revolution. This al-
lows the catalytic converter to reach its
operating temperature earlier.
More information on driving can be found
in “Operation” section (
page 197).
For information on off-road driving, see
“Driving instructions” (
page 203).
iWait for the gear selection process to
complete before setting the vehicle in
motion.
iYou can open the doors from inside at
any time. Open doors only when the
conditions are safe to do so.!If you hear a warning signal when driv-
ing off, you have forgotten to release
the parking brake.
Release the parking brake.
Warning!
G
It is dangerous to shift the selector lever out
ofP or N if the engine speed is higher than
idle speed. If your foot is not firmly on the
brake pedal, the vehicle could accelerate
quickly forward or in reverse. You could lose
control of the vehicle and hit someone or
something. Only shift into gear when the en-
gine is idling normally and when your right
foot is firmly on the brake pedal.Warning!
G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of loss of control.

71 Safety and Security
Driving and safety systems
Driving and safety systems
In this section you will find information on
the following driving safety systems:

ABS (Antilock Brake System)


BAS (Brake Assist System)


4-ETS (Electronic Traction System)


EBB (Electronic Brake Booster)


ESP (Electronic Stability Program)
ABS
The ABS regulates the brake pressure so
that the wheels do not lock during braking.
This allows you to maintain the ability to
steer your vehicle.
The ABS is functional above a speed of ap-
proximately 5 mph (8 km/h) independent
of road surface conditions (as long as the
differential locks are not engaged).
At the instant one of the wheels is about to
lock up, a slight pulsation can be felt in the
brake pedal, indicating that the ABS is in
the regulating mode. Keep firm and steady
pressure on the brake pedal while experi-
encing the pulsation.
iIn winter operation, the maximum ef-
fectiveness of the ABS, ESP, EBB and
4-ETS is only achieved with winter tires
(M + S tires), or snow chains as re-
quired.
Warning!
G
The following factors increase the risk of ac-
cidents:

Excessive speed, especially in turns


Wet and slippery road surfaces


Following another vehicle too closely
The ABS, BAS, ESP and 4-ETS cannot reduce
this risk.
Always adjust your driving style to the pre-
vailing road and weather conditions.
Warning!
G
Do not pump the brake pedal. Use firm,
steady brake pedal pressure instead. Pump-
ing the brake pedal defeats the purpose of
ABS and significantly reduces braking effec-
tiveness.

72 Safety and SecurityDriving and safety systemsContinuous steady brake pedal pressure
yields the advantages provided by the ABS,
namely braking power and the ability to
steer the vehicle.
On slippery road surfaces, the ABS will re-
spond even with light brake pressure. The
pulsating brake pedal can be an indication
of hazardous road conditions and func-
tions as a reminder to take extra care while
driving.
The
-
warning lamp in the instrument
cluster (page 24) lights up when you
turn the key to position 2. It goes out when
the engine is running.Braking
At the instant one of the wheels is about to
lock up, a slight pulsation can be felt in the
brake pedal, indicating that the ABS is in
the regulating mode.

Keep firm and steady pressure on the
brake pedal while experiencing the pul-
sation.
Emergency brake maneuver

Keep continuous full pressure on the
brake pedal.LOW RANGE– ABS
During off-road driving a special low range
system for the antilock brake system (ABS)
is operational with transfer case in position
LOW (
page 141).
An improved braking action (dig-in effect)
is obtained for vehicle speeds up to
37 mph (60 km/h) through a change in the
ABS control function.
More information can be found in the
“Practical hints” section (
page 240).
iTo alert following vehicles to slippery
road conditions you discover, operate
your hazard warning flashers as appro-
priate.
iIf the ABS is malfunctioning, the BAS,
EBB, ESP and 4-ETS are also switched
off.
Normal driving and braking functions
are still available.

74 Safety and SecurityDriving and safety systems4-ETS
The 4-ETS improves vehicle’s ability to uti-
lize available traction, especially under
slippery road conditions. The brakes are
applied to the spinning wheel and power is
allowed to flow to the wheel(s) with trac-
tion.
The 4-ETS function is available between ve-
hicle speeds of 0 mph (km/h) and 37 mph
(60 km/h).
The ESP warning lamp
v
in the instru-
ment cluster (
page 24) lights up when
you turn the key to position2. It goes out
when the engine is running.
The ESP warning lamp
v
starts to flash
at any vehicle speed, as soon as the tires
lose traction and the wheels begin to spin.More information can be found in the
“Practical hints” section (
page 238).
Warning!
G
When you see the ESP warning lamp
v

flashing in the speedometer dial, then pro-
ceed as follows:


While driving off, apply as little throttle
as possible.


While driving ease up on the accelera-
tor.


Adapt your speed and driving style to
the prevailing road conditions.
Failure to observe these guidelines could
cause the vehicle to skid.
The 4-ETS cannot prevent accidents result-
ing from excessive speed.
!The engine must be shut off when

the parking brake is being tested on
a brake test dynamometer.


the vehicle is being towed with one
axle raised.
Otherwise, the 4-ETS will engage the
brakes and seriously damage the brake
system.

function display shows one of the following
messages:


TC SHIFT CONDITIONS NOT FULFILLEDThe shift does not occur. At least one
shift condition was not met.

Repeat the shift procedure.


TC IN NEUTRAL The shift does not occur. The transfer
case is in neutral. The gear positionN
is displayed in the transfer case
indicator1.

Repeat the shift procedure.


TC SHIFT – CANCELLEDThe shift did not take place.

Repeat the shift procedure.


TRANSFER CASE – VISIT WORKSHOP!There is a malfunction in the system.

Have the vehicle checked at your au-
thorized Mercedes-Benz Light Truck
Center as soon as possible.
More information can be found in the
“Practical hints” section (
page 266).
!The shift procedure can only be per-
formed when:

The engine is running.


The selector lever for the automatic
transmission is in positionN.


The vehicle speed does not exceed
40 mph (70 km/h).
Warning!
G
If TC is in neutral, transmission positionP
will not hold vehicle. The parking brake must
be applied to hold vehicle in place.
iIf the SmartKey is in starter switch
position0 or1, an alarm will sound if
the transfer case is in positionN and
the driver’s door is opened.
Engage transfer case to gear position
HIGH or LOW.

166 Controls in detailDriving systemsRange of the sensors
To function properly, the sensors must be
free of dirt, ice, snow and slush. Clean the
sensors regularly, being careful not to
scratch or damage them.Minimum distance
The minimum distance between the sen-
sors and an obstacle is approximately
20 in (50 cm). If you encounter an obstacle
in this range, all the warning lamps light up
and you hear a warning signal. If the obsta-
cle is closer than the minimum distance,
the actual distance may no longer be indi-
cated by the system.
Center
approx. 59.1 in (150 cm)
Corners
approx. 40 in (100 cm)
!During parking maneuvers, pay special
attention to objects located above or
below the height of the sensors (e.g.
planters or trailer hitches). The Rear
Park Assist system will not detect such
objects at close range and damage to
your vehicle or the object may result.
Ultrasonic signals from outside sourc-
es (e.g. truck air brakes or jackham-
mers) may impair the operation of the
Rear Park Assist system.
