66 Getting startedParking and locking
Step firmly on parking brake pedal1.
When the engine is running, the
warning lamp; (USA only) or3
(Canada only) in the instrument cluster
comes on.
Switching off headlamps
Turn the exterior lamp switch toM
(page 59).
For more information, see “Lighting”
(
page 136).
Turning off the engine
Shift the automatic transmission to
positionP (
page 187).
Apply the parking brake (
page 65).
Warning!
G
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. Children could release the
parking brake and/or shift the automatic
transmission out of positionP, either of
which could result in an accident and/or
serious personal injury.
Warning!
G
Getting out of your vehicle with the
automatic transmission not fully engaged in
positionP is dangerous. Also, when parked
on an incline, positionP alone may not
prevent your vehicle from moving, possibly
hitting people or objects.
Always set the parking brake in addition to
shifting to positionP (
page 187).
When parked on an incline, also turn front
wheel towards the road curb.
i
If the engine cannot be turned off as de-
scribed, see “Emergency engine shut-down”
(
page 525).Warning!
G
Do not turn off the engine before the vehicle
has come to a complete stop. With the en-
gine not running, there is no power assis-
tance for the brake and steering systems. In
this case, it is important to keep in mind that
a considerably higher degree of effort is nec-
essary to brake and steer the vehicle.i
Always set the parking brake in addition to
shifting the automatic transmission to positionP
(
page 187).
When parked on an incline, also turn front wheel
towards the road curb.
72 Safety and SecurityOccupant safetyWarning!
G
To reduce the risk of injury when the front
air bags inflate, it is very important for the
driver and front passenger to always be in a
properly seated position and to wear their
respective seat belt.
For maximum protection in the event of a
collision always be in normal seated position
with your back against the seat backrest.
Fasten your seat belt and make sure it is
properly positioned on your body
(page 51).
Since the air bag inflates with considerable
speed and force, a proper seating and hands
on steering wheel position will help to keep
you at a safe distance from the air bag.
Occupants who are unbelted, out of position
or too close to the air bag can be seriously
injured or killed by an air bag as it inflates
with great force in the blink of an eye:
Sit properly belted in a nearly upright
position with your back against the seat
backrest.
Adjust the driver’s seat as far as possi-
ble rearward, still permitting proper op-
eration of vehicle controls. The distance
from the center of the driver’s breast-
bone to the center of the air bag cover
on the steering wheel must be at least
10 inches (25 cm) or more. You should
be able to accomplish this by a combina-
tion of adjustments to the seat and
steering wheel. If you have any prob-
lems, please see an authorized
Mercedes-Benz Light Truck Center.
Do not lean your head or chest close to
the steering wheel or dashboard.
Keep hands on the outside of steering
wheel rim. Placing hands and arms in-
side the rim can increase the risk and
potential severity of hand/arm injury
when driver’s front air bag inflates.
Adjust the front passenger seat as far as
possible rearward from the dashboard
when the seat is occupied.
Always sit nearly upright, properly use
the seat belts and use an appropriately
sized infant or toddler restraint or boost-
er seat recommended for the size and
weight of the child.
Failure to follow these instructions can
result in severe injuries to you or other
occupants.
If you sell your vehicle, it is important that
you make the buyer aware of this safety
information. Be sure to give the buyer this
Operator’s Manual.
Warning!
G
Accident research shows that the safest
place for children in an automobile is in the
rear seat.
74 Safety and SecurityOccupant safety
When you sell your vehicle we strongly
urge you to give notice to the subsequent
owner that it is equipped with an SRS by
alerting them to the applicable section in
the Operator’s Manual.
Do not bleach or dye seat belts as this
may severely weaken them. In a crash
they may not be able to provide ade-
quate protection.
No modifications of any kind may be
made to any components or wiring of
the SRS. This includes changing or
removing any component or part of the
SRS, the installation of additional trim
material, badges, etc. over the steering
wheel hub, front passenger front air bag
cover, outboard sides of the seat back-
rests, door trim panels, or door frame
trims, and installation of additional
electrical/electronic equipment on or
near SRS components and wiring. Keep
area between air bags and occupants
free from objects (e.g. packages, purs-
es, umbrellas, etc.).
Do not hang items such as coat hangers
from the coat hooks or handles over the
door. These items may turn into projec-
tiles and cause head and other injuries
when window curtain air bag is
deployed.
Air bag system components will be hot
after an air bag has inflated. Do not
touch.
Never place your feet on the instrument
panel, dashboard, or on the seat. Always
keep both feet on the floor in front of the
seat.
In addition, improper repair work on the
SRS creates a risk of rendering the SRS
inoperative or causing unintended air
bag deployment. Work on the SRS must
therefore only be performed by qualified
technicians. Contact an authorized
Mercedes-Benz Light Truck Center.
For your protection and the protection
of others, when scrapping the air bag
unit or emergency tensioning device,
our safety instructions must be fol-
lowed. These instructions are available
from your authorized Mercedes-Benz
Light Truck Center.
Given the considerable deployment
speed, required inflation volume, and
the textile structure of the air bags,
there is the possibility of abrasions or
other potentially more serious injuries
resulting from air bag deployment.
Warning!
G
Only use seat covers which have been
tested and approved by Mercedes-Benz for
your vehicle model. Using other seat covers
may interfere with or prevent the
deployment of the front side impact air bags
or the rear side impact air bags*. Contact an
authorized Mercedes-Benz Light Truck
Center for availability.

Driving safety systems
Emergency brake maneuver
Keep continuous full pressure on the
brake pedal.
Off-road – ABS
With the off-road driving program switched
on (
page 268), the ABS designed for
off-road use is automatically activated.
When applying the brakes at speeds below
approximately 18 mph (30 km/h), the
front wheels are locked cyclically to short-
en the braking distance (dig-in effect). This
affects steering the vehicle.
For more information, see “Practical hints”
(
page 413).
BAS
The Brake Assist System (BAS) operates in
emergency situations. If you apply the
brakes very quickly, the BAS automatically
provides full brake boost, thereby poten-
tially reducing braking distance.
Apply continuous full braking pressure
until the emergency braking situation is
over.
The ABS will prevent the wheels from
locking.
When you release the brake pedal, the
brakes function again as normal. The BAS
is then deactivated.
Warning!
G
When the ABS is malfunctioning, the BAS,
the ESP
®, and the 4-ETS are also switched
off. The basic driving and braking functions
are still available.
When the ABS is malfunctioning, the wheels
may lock during hard braking, reducing
steering capability and extending the brak-
ing distance.
Warning!
G
The ABS cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase braking or steering efficiency be-
yond that afforded by the condition of the
vehicle brakes and tires or the traction
afforded. The ABS cannot prevent acci-
dents, including those resulting from
excessive speed in turns, following another
vehicle too closely, or hydroplaning. Only a
safe, attentive, and skillful driver can pre-
vent accidents. The capabilities of an ABS
equipped vehicle must never be exploited in
a reckless or dangerous manner which
could jeopardize the user’s safety or the
safety of others.
Warning!
G
If the BAS is malfunctioning, the brake sys-
tem is still functioning, but without the addi-
tional brake boost available that BAS would
normally provide in an emergency braking
maneuver. Therefore, the braking distance
may increase.
101 Safety and Security
Driving safety systems

(page 413).
Off-road – ESP
®
With the off-road driving program switched
on (
page 268), the ESP
® designed for
off-road use is automatically activated. At
speeds below 27 mph (45 km/h), the
ESP
® assists in over-/understeering, thus
improving vehicle traction.
ESP® Trailer Stabilization
If the trailer you are towing should begin to
sway, the rig can only be stabilized by
immediately applying the brakes hard.
Steering during this maneuver will not help
to stabilize the rig.
ESP® will assist you in such situations.
ESP® recognizes when the trailer starts
swaying and will apply the brakes to re-
duce the vehicle speed to a non-critical
speed that allows the vehicle-trailer combi-
nation to stabilize.The ESP
® Trailer Stabilization is functional
at vehicle speeds above approximately
40 mph (65 km/h) when the ESP
® is
switched on.
EBP
The EBP enhances braking effectiveness
by allowing the rear brakes to supply a
greater proportion of the braking effort
without a loss of vehicle stability.
For more information, see the “Practical
hints” section (
page 416) and
(
page 448).
Warning
G
The system will not be able to assist when
the trailer jackknifes
on wet or icy roads
on roads with slippery surface
in sand or gravel
Trailers with a high center of gravity may tip
over before the system recognizes swaying
of the trailer.
i
If the ESP
® has switched off due to a mal-
function, ESP® cannot stabilize the rig.
Warning!
G
If the EBP is malfunctioning, the brake sys-
tem is still functioning. However, the rear
wheels may lock during hard braking, caus-
ing you to lose control over the vehicle and
possibly causing an accident. Adjust your
driving style to the non-operating status of
the EBP.
134 Controls in detailMemory function*Prior to operating the vehicle, the driver
should check and adjust the seat height,
seat position fore and aft, and seat back-
