Parking and locking
You have now completed your first drive.
You have properly stopped and parked
your vehicle. End your drive as follows.Parking brake
1Parking brake lever
2Release button
Pull lever1 up as many notches as
possible.
When the engine is running, the warn-
ing lamp; (USA only) or3
(Canada only) in the instrument cluster
will be illuminated.
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 ve-
hicle.
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 gear selector lever to
positionP.
Slowly release brake pedal.
When parked on an incline, turn front
wheels towards the road curb.
Turn the SmartKey in the starter switch
position0 and remove the SmartKey
from the starter switch.
Take the SmartKey and lock vehicle
when leaving.

For more information, see “Exterior lamp
switch” (
page 110).
Turning off engine
Place the gear selector lever in
positionP.
Turn SmartKey in the starter switch to
position0 and remove the SmartKey

The immobilizer is activated.
Warning!G
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle. 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 gear 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 gear se-
lector lever not fully engaged in positionP is
dangerous. 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.
i
Always set the parking brake in addi-
tion to shifting to positionP.
On slopes, turn the front wheels to-
wards the road curb.

driver’s door open, a warning sounds if
the vehicle’s exterior lamps are not
switched off.
Warning!G
To prevent possible personal injury, always
keep hands and fingers away from the door
openings when closing the doors. Be espe-
cially careful when small children are
around.
Before closing doors, make sure there is no
possibility of someone getting caught in a
door during closing.
Warning!G
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle. Do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. Unsuper-
vised use of vehicle equipment may cause
an accident and/or serious personal injury.

Children in the vehicle
If an infant or child is traveling with you in
the vehicle:
Secure the child using an infant or child
restraint appropriate to the age and
size of the child.
Make sure the infant or child is proper-
ly secured at all times while the vehicle
is in motion.
Infant and child restraint seats and infor-
mation on choosing an appropriate re-
straint system can be obtained from any
Mercedes-Benz Light Truck Center.Infant and child restraint systems
Use only a BabySmart
TM1 compatible child
restraint for the front passenger seat in
this vehicle.
We recommend that all infants and
children be properly restrained at all times
while the vehicle is in motion. All lap-shoul-
der belts except the driver’s seat belt and
the rear center seat belt have special seat
belt retractors for secure fastening of child
restraints.
To fasten a child restraint, follow manufac-
turer’s instructions for mounting child re-
straints. Then pull shoulder belt out
completely and let it retract. During the
seat belt retraction a ratcheting sound can
be heard to indicate that the special seat
belt retractor is activated. The belt is now
locked. Push down on child restraint to
take up any slack.To deactivate, release seat belt buckle and
let seat belt retract completely. The seat
belt can again be used in the usual
manner.

with mounting fittings for tether an-
chorages, see “Installation of infant
and child restraint system”

seat anchors, see (

Warning!G
Never release the seat belt buckle while the
vehicle is in motion, since the special seat
belt retractor will be deactivated.

80 Safety and Security
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
t h a t t h e w h e e l s d o n o t l o c k d u r i n g b r a k i n g .
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.
i
In winter operation, the maximum ef-
fectiveness of the ABS, ESP, EBB, and
4-ETS is only achieved with winter tires
or snow chains as required.
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.
Page 82 of 417

81 Safety and Security
Driving and safety systems
Continuous 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 -indicator lamp in the instrument
cluster (
page 24) comes on when you
turn the SmartKey to position2. 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 157).
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.
For more information, see “Practical hints”
(
page 290).
i
If the ABS is malfunctioning, the BAS,
EBB, ESP, and 4-ETS are also switched
off.
Normal driving and braking functions
are still available.
