ating your vehicle:
Rthe safety notes in these operating instruc-
tions
Rthe technical data in these Operating Instruc-
tions
Rtraffic laws and regulations
Rmotor vehicle laws and safety standards
There are various warning stickers affixed to the
vehicle. If you remove warning stickers, you and
others may fail to recognizet he dangers. Leave
the warning stickers in their original position.
GWARNING
Modifications to electronic components, their software as well as wiring can impair their
function and/or the function of other net-
worked components. In particular, systems
relevant to safety could also be affected. As a
result, these may no longer function as inten-
ded and/or jeopardize the operating safety of
the vehicle. There is an increased risk of an
accident and injury.
Never tamper with the wiring as well as elec-
tronic components or their software. You
should have all work to electrical and elec-
tronic equipment carried out at aqualified
specialist workshop.
The general operating permit for your vehicle
could be rendered invalid if you carry out mod-
ifications to electronic components, their soft-
ware as well as wiring.
GWARNING
Gases and fluids from substances that con-
stitute ahealth hazard or react aggressively
can escape even from securely closed con-
tainers. When transporting such substances
in the vehicle interior, your ability to concen-
trate or your health could be affected during
the journey. Malfunctions, short circuits or
electrical components ystem failures may
also result. There is arisk of an accident and
fire.
Do not store or transport any substances in
the vehicle interior which are hazardous to
health or react aggressively.
These instructions must also be observed for
vehicles where the cargo compartmentisn ot
fully separated from the driver's cab.
Partition with door/window: always keep the

There is, however, no system availabletoday
that can completely rule out injury or death.
It is also not possible to rule out arisk of injury
caused by an air bag due to the high speed at
which the air bag must be deployed.
Important safety notes
GWARNING
If you do not sit in the corrects eat position,
the air bag cannot protec tasintended and
could even cause additional injury when
deployed. This poses an increased risk of
injury or even fatal injury.
To avoid hazardous situations, alwaysm ake
sure that all of the vehicle's occupants:
Rhave fastened their seat belts correctly,
including pregnant women
Rare sittin gcorrectly and maintain the great-
est possible distance to the air bags
Rfollow the following instructions
Always make sure that there are no objects
between the air bag and the vehicle's occu-
pants.
RCorrectly adjust the seats before driving off.
Always make sure the seat backrest sare
positioned as close to the vertical as possible.
The center of the head restraints should sup-
port the back of the head at about eye level.
RMove the driver's and front-passenger seat as
far back as possible. The driver's seat position
must be such that the vehicle can be driven
safely.
RKeep hands on the outside of the steering
wheel rim. This allows the air bag to deploy
fully.
RAlways sit with your back against the seat
backrest when driving. Do not lean forward,
on the door or against the side window. Oth-
erwise, you are in the air bag deployment
area.
RAlways keep your feet in the footwell in front
of the seat. Do not,f or example, place your
feet on the dashboard. Otherwise, your feet
are in the air bag deployment area.
RSuitable restraint systems must alwaysb e
used for persons under 5ft(1.50 m) in height.
The seat belt cannot be worn correctly by
persons who do not reach this height. If children are also traveling in the vehicle,
please take note of the followingp
oints.
RChild restraint systems should preferably be
installed on the rear seats.
ROnly secureachild on the front-passenger
seat in arearward-facing child restraint sys-
tem if the front-passenger front air bag is
deactivated. If the PASSENGER AIR BAG OFF
indicator lamp is permanently lit, the front-
passenger front air bag is deactivated
(
Ypage 44).
RMake sure you observe the instructions and
safety notes on "Occupan t Classification Sys-
tem (OCS)" (Ypage 50) and "Children in the
vehicle" (Ypage 56), as well as the child
restraint system manufacturer's installation
instructions.
Objects in the passenger compartment
could prevent an air bag from functioning
properly. To prevent risks due to the required
air bag speed after deployment, ensure the fol-
lowing before starting the journey:
Rthere are no persons, animals or objects
between the vehicle occupantsa nd an air
bag.
Rthere are no object sbetween the seat, door
and B-pillar.
Rno hard objects, e.g. coat hangers, hang on
the grab handles or coat hooks.
Rno accessories, such as cup holders, are
attached to the vehicle within the deployment
area of an air bag, e.g. to doors or side win-
dows.
Rthere are no heavy, sharp or fragile object sin
the pocketsofi tems of clothing. Such items
should be suitably stowed elsewhere.
GWARNING
If you modify the air bag cover or affix objects
such as stickers to it, the air bag can no longer
function correctly. There is an increased risk
of injury.
Never modify an air bag cover or affix objects
to it.

Occupant Classificatio nSystem
(OCS)
Introduction
The Occupant Classification System (OCS) cat-
egorizes the personint he front-passenger seat.
Depending on that result, the front-passenger
front air bag is either enabled or deactivated.
The syste mdoes not disable:
Rthe side impact air bag
Rthe window curtai nair bag
Rthe Emergency Tensioning Devices
Conditions
To be classified correctly ,the front passenger
must sit:
Rwith the seatb eltfastened correctly
Rin an almost upright position with their back
against the seatb ackrest
Rwith their feet resting on the floor, if possible
If the front passenger does not observe these
conditions, OCS may produce afals ec lassifica-
tion, e.g. because the front passenger:
Rtransfers their weight by supporting them-
selve sonav ehiclea rmrest
Rsits in such awaythat their weight is raised
from the seatc ushion
If it is absolutely necessary to instal lachild
restraint syste monthe front-passenger seat, be
sure to observe the correct positioning of the
child restraint system. Never place objects
under or behind the child restraint system, e.g.
cushions. The entire bas eofthe child restraint
syste mmust alway srest on the seatc ushion of
the front-passenger seat. The backres tofthe
forward-facing child restraint syste mmust lie as
flat as possible against the backres tofthe front-
passenger seat.
The child restraint syste mmust not touch the
roof or be subjected to aloadbyt he head
restraint. Adjust the angl eofthe seatb ackrest
and the headr estraint position accordingly.
Only then can OCS be guaranteed to function
correctly .Always observe the child restraint sys-
tem manufacturer's installation instructions.

restraint system control uni ttriggers the Emer-
gency Tensioning Device sinthe event of afron-
tal or rear-end collision.
An Emergency Tensioning Device can only be
triggered if:

Important safety notes
GWARNING
While opening the side windows, body parts
could become trapped between the side win-
dow and the door frame as the side window
moves. There is arisk of injury.
Make sure that nobody touches the side win-
dow during the opening procedure. If some-
body becomes trapped, release the switch or
pull the switch to close the side window again.
GWARNING
While closing the side windows, body parts in
the closing area could become trapped. There is ar isk of injury.
When closing make sure that no parts of the
body are in the closing area. If somebody
becomes trapped, release the switch or press
the switch to open the side window again.
GWARNING
If children operate the side windows they
could become trapped, particularly if they are left unsupervised. There is arisk of injury.
Activate the override feature for the rear side
windows. When leaving the vehicle, always
take the SmartKey with you and lock the vehi-
cle. Never leave children unsupervised in the
vehicle.
GWARNING
If persons, particularly children are subjected to prolonged exposure to extrem eheat or
cold, there is arisk of injury, possibly even
fatal. Never leave children unattended in the
vehicle.
Side window reversing feature
The front side windows are equipped with an
automatic reversing feature. If asolid object
blocks or restrictsas ide window from moving
upwards during the automatic closing process,
the side window opens again automatically .Dur-
ing the manual closing process, the side window
only opens again automatically after the corre-
sponding switch is released. The automatic
reversing feature is only an aid and is no substi-
tute for your attention when closing aside win-
dow.
GWARNING
The reversing feature does not react:
Rto soft, light and thin objects, e.g. small fin-
gers
Rwhile resetting
This means that the reversing feature cannot
prevent someone being trapped in these sit-
uations. There is arisk of injury.
Make sure that no body parts are in close
proximity during the closing procedure. If
someone becomes trapped, press the switch
to open the side window again.
