Product information

Introduction
Product information
Please observe the following in your own
best interest:
We recommend using Genuine
Mercedes-Benz Parts as well as conversion
parts and accessories explicitly approved
by us for your vehicle model.
We have tested these parts to determine
their reliability, safety and special
suitability for Mercedes-Benz vehicles.We are unable to make an assessment for
other products and therefore cannot be
held responsible for them, even if in indi-
vidual cases an official approval or authori-
zation by governmental or other agencies
should exist. Use of such parts and acces-
sories could adversely affect the safety,
performance or reliability of your vehicle.
Please do not use them.Genuine Mercedes-Benz Parts as well as
conversion parts and accessories
approved by us are available at your
authorized Mercedes-Benz Light Truck
Center where you will receive comprehen-
sive information, also on permissible tech-
nical modifications, and where proper
installation will be performed.

75 Safety and Security
Occupant 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.Front air bags
1Driver air bag
2Passenger air bag
Driver and front passenger air bags are
deployed:

in the event of certain frontal impacts

if impact exceeds a preset deployment
threshold

independently of the side impact air
bags
Warning!G
Only use seat covers which have been test-
ed 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 autho-
rized Mercedes-Benz Light Truck Center for
availability.
iThe front air bags in this vehicle have been
designed to inflate in two stages. This allows the
air bag to have different rates of inflation that are
based on the rate of relevant vehicle decelera-
tion as assessed by the air bag control unit.
On the front passenger-side, the front air bag
deployment is additionally influenced by the
passenger’s weight category as identified by the
Occupant Classification System (OCS)
(
page 77).
The lighter the front passenger side occupant,
the higher the vehicle deceleration rate required
for the second stage inflation of the air bag.

126 Controls in detail
Locking and unlocking
Automatic central locking
The doors and the tailgate lock automati-
cally when the ignition is switched on and
the wheels are turning at vehicle speeds of
approximately 9 mph (15 km/h) or more.
For information on towing the vehicle, see
“Towing the vehicle” (
page 513).
You can deactivate the automatic locking
mode using the control system
(
page 183).
Locking and unlocking from the inside
You can lock or unlock the doors and the
tailgate from inside using the central lock-
ing or unlocking switch. This can be useful,
for example, if you want to lock the vehicle
before starting to drive.
The fuel filler flap cannot be locked or un-
locked with the central locking or unlock-
ing switch.Even with the SmartKey with KEYLESS-GO*
removed from the vehicle, the tailgate
closing switch can be operated. Therefore,
do not leave children unattended in the ve-
hicle, or with access to an unlocked vehicle.
A child’s unsupervised access to a vehicle
could result in an accident and/or serious
personal injury.
iTo prevent a possible inadvertent lockout,
the tailgate will open automatically if a SmartKey
with KEYLESS-GO* is recognized inside the
vehicle.
iYou can open a locked door from the inside.
Open door only when conditions are safe to do
so.
iThe doors unlock automatically after an
accident if the force of the impact exceeds a pre-
set threshold.
The vehicle automatically locks when the
ignition is switched on and the wheels are
turning at vehicle speeds of approximately
9 mph (15 km/h) or more. You could therefore
lock yourself out when the vehicle

is pushed or towed

is on a test stand
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. A child’s unsupervised
access to a vehicle could result in an
accident and/or serious personal injury.
