Operating safety
Important safetynotes
GWARNING
If you do not have the prescribed service/
maintenanc ework or any required repairs
carried out, this can result in malfunctions or system failures. There is arisk of an accident.
Always have the prescribed service/mainte-
nanc ework as well as any required repairs
carried out at aqualified specialist workshop.
GWARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with
hot parts of the exhaust system. There is arisk
of fire.
When driving off road or on unpaved roads,
checkt he vehicle's underside regularly. In
particular, remove parts of plants or other
flammable materials which have become
trapped. In the case of damage, contact a
qualified specialist workshop.
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 jeopardiz ethe operatin gsafety of
the vehicle. There is an increased risk of an
accidenta nd injury.
Never tamper with the wiring as well as elec-
tronic component sortheir software. You
should have all work to electrical and elec-
tronic equipment carried out at aqualified
specialist workshop.
!There is arisk of damage to the vehicle if:
Rthe vehicle becomes stuck ,e.g. on ahigh
curb or an unpaved road
Ryou drive too fast over an obstacle, e.g. a
curb, aspeed bump or apothole in the road
Rah eavy objec tstrikes the underbody or
parts of the chassis
In situation slike this, the body, the under-
body, chassis parts, wheels or tires could be
damaged without the damage being visible.
Components damaged in this way can unex-
pectedly fail or, in the case of an accident, no
longer withstand the loads they are designed
to.
If the underbody paneling is damaged, com-
bustible materials such as leaves, grass or
twigs can gather between the underbody and
the underbody paneling. If these materials
come in contact with hot parts of the exhaust system, they can catc hfire.
In such situations, have the vehicle checked
and repaired immediately at aqualified spe-
cialist workshop. If on continuin gyour jour-
ney you notice that driving safety is impaired,
pull over and stop the vehicle immediately,
paying attention to road and traffic condi-
tions. In such cases, consult aqualified spe-
cialist workshop.

Event datar ecorders
This vehicle is equipped with an event data
recorder (EDR). This vehicle is equipped with an
event data recorder (EDR). The main purpose of
an EDRistor ecord, in certain crash or near
crash-lik esituations, such as an air bag deploy-
ment or hittin garoad obstacle, data that will
assist in understanding how avehicle's systems
performed. The ED Risdesigned to record data
related to vehicle dynamics and safety systems
for ashort period of time, typically 30 seconds
or less. The ED
Rinthis vehicle is designed to record
such data as:
RHow various systems in your vehicle were
operating
RWhether or not the driver and passenger
safety belts were buckled/fastened
RHow far (if at all) the driver was depressing the accelerator and/or brake pedal and
RHow fast the vehicle was traveling.
These data can help provide abetter under-
standin gofthe circumstances in which acci-
dents and injuries occur. NOTE: ED Rdata are
recorded by your vehicle only if anon-trivial
crash situation occurs; no data is recorded by
the ED Runder normal driving conditions and no
personal data (e.g. name, gender, age and acci-
dent location) are recorded. However, other par- ties, such as law enforcement could combine
ED Rd ata with the type of personally identifying
data routinely acquired during acrash investi-
gation.
Access to the vehicle and/or the ED Risneeded
to read data that is recorded by the EDR, and
special equipment is required. In addition to the
vehicle manufacturer, other parties that have

Requirements
To be classified correctly, the front passenger
must sit:
Rwith the seat belt fastened correctly
Rin an almost upright position with their back
against the seat backrest
Rwith their feet restin gonthe floor, if possible
If the front passenger does not observe these
conditions, OCS may produce afalse classifica-
tion, e.g. because the front passenger:
Rtransfers their weight by supporting them-
selves on avehicle armrest
Rsits in such away that their weight is raised
from the seat cushion
If you install achild restraint system on the
front-passenger seat, be sure to observe the
correctp ositioningofthe child restraint system.
Never place object sunder or behind the child
restraint system, e.g. acushion. The entir ebase
of the child restraint system must alwaysr est on
the seat cushion of the front-passenger seat.
The backrest of the forward-facing child
restraint system must lie as flat as possible
against the backrest of the front-passenger
seat.
The child restraint system must not touch the
roof or be subjected to aload by the head
restraint. Adjust the angle of the seat backrest
and the head restraint position accordingly.
Only then can OCS be guaranteed to function
correctly. Always observe the child restraint sys-
tem manufacturer's installation and operating
instructions.
Occupant Classification System opera-
tion (OCS)
:PASSENGER AIR BAG ON indicator lamp
;PASSENGER AIR BAG OFF indicator lamp
The indicator lamps inform you whether the
front-passenger front air bag is deactivated or
enabled.
XPress the Start/Stop button once or twice, or
turn the SmartKey to position 1or2 in the
ignition lock.
The system carries out self-diagnostics.
The PASSENGER AIR BAG OFF and PASSENGER AIR BAG ON indicator lamps must light up simul-
taneously for approximately six seconds.
The indicator lamps display the status of the
front-passenger front air bag.
RPASSENGER AIR BAG ON lights up for 60 sec-
onds, subsequently both indicator lamps are
off (PASSENGER AIR BAG ON and OFF): the
front-passenger front air bag is able to deploy
in the event of an accident.
RPASSENGER AIR BAG OFF lights up: the front-
passenger front air bag is deactivated. It will
then not be deployed in the event of an acci-
dent.
If the PASSENGER AIR BAG ON indicator lamp is
off, only the PASSENGER AIR BAG OFF indicator lamp shows the status of the front-passenger
front air bag. The PASSENGER AIR BAG OFF
indicator lamp may be lit continuously or be off.
If the status of the front-passenger front air bag
changes while the vehicle is in motion,ana ir bag
display message appears in the instrument clus-
ter (
Ypage 187). When the front-passenger
seat is occupied, alwaysp ay attention to the
PASSENGER AIR BAG OFF indicator lamp. Be
aware of the status of the front-passenger front air bag both before and during the journey.

Safety

GWARNING
If the PASSENGER AIR BAG OFF indicator
lamp is lit, the front-passenge rfront air bag is
disabled. It wil lnot be deploye dinthe event of
an accident and cannot perform its intended
protective function. Apersonint he front-
passenger seat coul dthen, for example, come
into contact with the vehicle's interior, espe-
cially if the personiss itting too close to the
dashboard. This posesani ncreased risk of
injury or even fatal injury.
When the front-passenge rseat is occupied,
alway sensure that:
Rthe classification of the personint he front-
passenger seat is correct and the front-
passenger front air bag is enabled or disa-
bledina ccordance with the personint he
front-passenge rseat
Rthe front-passenge rseat has been moved
back as far back as possible.
Rthe personiss eated correctly.
Make sure ,both before and during the jour-
ney, that the status of the front-passenger
front air bag is correct.
GWARNING
If you secure achild in arearward-facing child
restraint system on the front-passenge rseat
and the PASSENGER AIR BAG OFF indicator
lamp is off, the front-passenge rfront air bag
can deploy in the event of an accident. The
child coul dbestruck by the air bag .This poses
an increased risk of injury or even fatal injury.
Make sure that the front-passenge rfront air
bag has been deactivated. The PASSENGER
AIR BAG OFF indicator lamp must be lit.
NEVER use arearward-facing child restraint
on aseat protected by an ACTIVE FRONT AIR-
BAG in front of it; DEATH or SERIOUS INJURY
to the child can occur.
If the PASSENGER AIR BAG OFF indicator lamp
stays off, do not instal larearward-facing child
restraint system on the front-passenge rseat.
You can find more information on OCS under
"Problems with the Occupant Classification Sys-
tem" (
Ypage4 9).
GWARNING
If you secure achild in aforward-facing child
restraint system on the front-passenge rseat
and you position the front-passenge rseat too
close to the dashboard, in the event of an
accident, the child could:
Rcome into contact with the vehicle's inte-
rior if the PASSENGER AIR BAG OFF indi-
cator lamp is lit, for example
Rbe struck by the air bag if the PASSENGER
AIR BAG OFF indicator lamp is off
This poses an increased risk of injury or even fatal injury.
Move the front-passenge rseat as far back as
possible.A lways make sure that the shoulder
belts trap is correctly routed from the vehicle
beltg uide to the shoulderb eltguide on the
child restraint system. The shoulderb eltstrap
must be routed forwards and downwards
from the vehicleb eltguide. Always observe
the child restraint system manufacturer's
installation instructions.
If OCS determines that:
RThe front-passenge rseat is unoccupied,t he
PASSENGER AIR BAG OFF indicator lamp
lights up after the system self-test and
remains lit. This indicates that the front-
passenger front air bag is deactivated.
RThe front-passenge rseat is occupied by a
child of up to twelve months old, in astandard
child restraint system, the PASSENGER AIR
BAG OFF indicator lamp lights up after the
system self-test and remains lit. This indi-
cates that the front-passenge rfront air bag is
deactivated.
But even in the case of atwelve-month-old
child ,inas tandard child restraint system, the
PASSENGER AIR BAG OFF indicator lamp can
go out after the system self-test. This indi-
cates that the front-passenge rfront air bag is
activated. The result of the classification is
dependent on, among other factors, the child
restraint system and the child's stature. Make
sure that the conditions for acorrect classi-
ficatio nare met. If the PASSENGER AIR BAG
OFF indicator lamp remains off, do not install
ac hild restraint system on the front-
