12 IntroductionOperator’s ManualMaintenance
The Service Booklet describes all the nec-
essary maintenance work which should be
performed at regular intervals.
Always have the Service Booklet with you
when you take the vehicle to your autho-
rized Mercedes-Benz Light Truck Center
for service. The service advisor will record
each service in the booklet for you.
Roadside Assistance
The Mercedes-Benz Roadside Assistance
Program provides factory-trained technical
help in the event of a breakdown. Calls to
the toll-free Roadside Assistance number
1-800-FOR-MERCedes (in the USA)
1-800-387-0100 (in Canada)
will be answered by Mercedes-Benz Cus-
tomer Assistance Representatives
24 hours a day, 365 days a year.
Roadside Assistance will be provided in ac-
cordance with standard program guide-
lines which include providing service to the
vehicle up to a reasonable distance from a
paved roadway. We will make every effort
to assist in a breakdown situation, howev-
er, the accessibility of your vehicle will be
determined by our authorized
Mercedes-Benz Light Truck Center techni-
cian or the tow service provider on a case
by case basis and may be a factor in our
ability to respond.Additional charges may be applicable for a
breakdown location determined not to be a
reasonably accessible roadside location as
determined by our authorized technician
and tow service provider.
For additional information refer to the
Mercedes-Benz Roadside Assistance Pro-
gram brochure in your glove box.

50 Getting startedParking and locking
Parking and lockingYou have now completed your first drive.
You have properly stopped and parked
your vehicle. End your drive as follows.
Parking brake
1Lever
2Button
Pull lever1 up as many notches as pos-
sible.
When the engine is running, the indica-
tor lamp
;
(USA only) or
3
(Can-
ada only) in the instrument cluster will
be illuminated.
Warning!
G
Wait until the vehicle is stationary before re-
moving the key from the starter switch. The
vehicle cannot be steered when the key is
removed.Warning!
G
With the engine not running, there is no
power assistance for the brake and the
steering system. In this case, it is important
to keep in mind that a considerably higher
degree of effort is necessary to stop or steer
the vehicle.
Warning!
G
Do not park this vehicle in areas where com-
bustible materials such as grass, hay or
leaves can come into contact with the hot
exhaust system, as these materials could be
ignited and cause a vehicle fire.
To reduce the risk of personal injury as a re-
sult of vehicle movement, before turning off
the engine and leaving the vehicle always:

Keep right foot on brake pedal.


Pull the parking brake lever up as many
notches as possible.


Move the selector lever to positionP.


Slowly release brake pedal.


When parked on an incline, turn front
wheels towards the road curb.


Turn the key to starter switch position0
and remove.


Take the key and lock vehicle when leav-
ing.

More information can be found in the
“Controls in detail” section (
page 100).
Turning off engine
Place the selector lever in positionP.

Turn key in the starter switch to
position0 and remove it.
The immobilizer is activated.

Press the seat belt release button
(page 41).
Allow the retractor to completely re-
wind the seat belt by guiding the latch
plate.
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 vehicle, or with access to an unlocked
vehicle. Children could release the parking
brake and/or move the selector lever from
positionP, either of which could result in an
accident and/or serious personal injury.Warning!
G
Getting out of your vehicle with the selector
lever not fully engaged in positionP is dan-
gerous. Also, when parked on an incline,
positionP alone may not prevent your vehi-
cle from moving, possibly hitting people or
objects.
Always set the parking brake in addition to
shifting to positionP.
When parked on an incline, turn front wheels
towards the road curb.
iAlways set the parking brake in addi-
tion to shifting to position P.
On slopes, turn the front wheels to-
wards the curb.
iThe key can only be pulled out when:

it has been turned to position0 in
the starter switch


the gear selector lever for the auto-
matic transmission is in positionP


you are not braking with the service
brake
!With the key removed and the driver’s
door open, a warning sounds if the ve-
hicles exterior lamps are not switched
off.

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.

76 Safety and SecurityDriving and safety systems
Switching off the ESP
To improve the vehicle's traction, turn off
the ESP in driving situations where it would
be advantageous to have the drive wheels
spin and thus cut into surfaces for better
grip such as:

starting out on slippery surfaces and in
deep snow in conjunction with snow
chains.


sand or gravel.


when driving off-road.
When the ESP is turned off


engine torque is not limited.


the drive wheels can spin.
Warning!
G
The ESP cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase the traction afforded. The ESP
cannot prevent accidents, including those
resulting from excessive speed in turns, fol-
lowing another vehicle too closely, or aqua-
planing. Only a safe, attentive, and skillful
driver can prevent accidents. The capabili-
ties of a ESP equipped vehicle must never be
exploited in a reckless or dangerous manner
which could jeopardize the user’s safety or
the safety of others.!Driving the vehicle with varied size tires
will cause the wheels to rotate at differ-
ent speeds, possibly causing the ESP to
activate. For this reason, all wheels, in-
cluding the spare wheel, must have the
same tire outside diameter.
!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 ESP will engage the
brakes and seriously damage the brake
system.
iThe ABS, BAS and ESP are automatical-
ly switched off when the differential
locks are switched on (
page 145).
Warning!
G
The ESP should not be switched off during
normal driving other than in the circum-
stances described below. Disabling of the
system will reduce vehicle stability in stan-
dard driving maneuvers.
