Operating safety
Important safety notes
GWARNING
If you do not have the prescribed service/
maintenance work or any required repairs
carried out, this can result in malfunctions or system failures. There is a risk of an accident.
Always have the prescribed service/mainte-
nance work as well as any required repairs
carried out at a qualified 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 a risk of fire.
When driving off road or on unpaved roads,
check the 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 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 a qualified
specialist workshop.
!There is a risk of damage to the vehicle if:
Rthe vehicle becomes stuck, e.g. on a high
curb or an unpaved road
Ryou drive too fast over an obstacle, e.g. a
curb or a hole in the road
Ra heavy object strikes the undercarriage or
parts of the chassis
In situations like this, the body, the undercar-
riage, 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 strain 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 catch fire.
In such situations, have the vehicle checked
and repaired immediately at a qualified spe-
cialist workshop. If on continuing your 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 a qualified spe-
cialist workshop.
Hybrid vehicles have a combustion engine and
an electric motor. The voltage supply for oper-
ating the vehicle electrically is provided by the
vehicle's high-voltage electrical system.
GDANGER
The vehicle's high-voltage electrical system is under high voltage. If you modify components
in the vehicle's high-voltage electrical system
or touch damaged components, you may be
electrocuted. The components in the vehi-
cle's high-voltage electrical system may be
damaged in an accident, although the damage
is not visible. There is a risk of fatal injury.
Following an accident, do not touch any high-
voltage components and never modify the
vehicle's high-voltage electrical system. Have
the vehicle towed away after an accident and

before reactivation.
High-voltage battery
GWARNING
In the event of a vehicle fire, the internal pres- sure of the high-voltage battery can exceed a
critical value. In this case flammable gas
escapes through a ventilation valve on the
underbody. The gas can ignite. There is a risk
of injury.
Leave the danger zone immediately. Secure
the danger area at a suitable distance, whilst
observing legal requirements.
GWARNING
If the housing of the high-voltage battery has
been damaged, electrolyte and gases may
leak out. These are poisonous and caustic.
There is a risk of injury.
Avoid contact with skin, eyes or clothing.
Immediately rinse electrolyte splashes off
with water and seek medical attention
straight away.
!Exhaustive discharge caused by the vehicle
standing idle for lengthy periods can damage
the high-voltage battery.
Hybrid vehicles: if the vehicle is idle for
lengthy periods, run it for a few minutes once every six weeks to charge up the high-voltage
battery. During the charging process, switch
off all electrical consumers, e.g. the auto-
matic climate control or the seat heating.
PLUG-IN HYBRID vehicles: make sure that
the high-voltage battery is connected to a
charging station during long periods when the
vehicle is standing idle.
PLUG-IN HYBRID vehicles: charging the high-
voltage battery (

Safety

If it is absolutely necessary to install a child
restraint system on the 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. Fully retract the seat cushion length.
The entire base of the child restraint system
must always rest 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 a load 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 indicate whether the front-
passenger front air bag is activated or deactiva-
ted.
XPress the start/stop button once or twice, or
turn the SmartKey to position 1or 2in the
ignition lock.
The system carries out a self-diagnosis test.
The PASSENGER AIR BAG OFF and PASSENGER
AIR BAG ON indicator lamps must light up simul-
taneously for about six seconds.
The indicator lamps then display the status of
the front-passenger front air bag:
RPASSENGER AIRBAG ON lights up: the front-
passenger front airbag is enabled. If, in the case of an accident, all deployment criteria
are met, the front-passenger front air bag is
deployed.
RPASSENGER AIRBAG OFF lights up: the front-
passenger front airbag is disabled. It will then
not be deployed in the event of an accident.
If the status of the front-passenger front air bag changes whilst the vehicle is in motion, an air
bag display message may appear in the instru-
ment cluster (
Ypage 289). Always observe the
PASSENGER AIR BAG ON and PASSENGER AIR
BAG OFF indicator lamps when the front-
passenger seat is occupied. Make sure that the
status of the front-passenger front air bag is
correct before and during a journey.
GWARNING
If the PASSENGER AIR BAG OFF indicator
lamp is lit, the front-passenger front air bag is
disabled. It will not be deployed in the event of
an accident and cannot perform its intended
protective function. A person in the front-
passenger seat could then, for example, come
into contact with the vehicle's interior, espe-
cially if the person is sitting too close to the
dashboard. This poses an increased risk of
injury or even fatal injury.
When the front-passenger seat is occupied,
always ensure that:
Rthe classification of the person in the front- passenger seat is correct and the front-
passenger front air bag is enabled or disa-
bled in accordance with the person in the
front-passenger seat
Rthe front-passenger seat has been moved
back as far back as possible.
Rthe person is seated 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 a child in a rearward-facing child
restraint system on the front-passenger seat
and the PASSENGER AIR BAG ON indicator
lamp is lit up, the front-passenger front air bag may deploy in an accident. The child could be
