Rthe6 restraint system warning lamp in the
instrument cluster lights up after an accident
Rthe vehicle is badly damaged, e.g. after an
accident, and the restraint system compo-
nents were not activated
Rthe vehicle is badly damaged and has to be
towed or transported
XIf possible, move the vehicle out of the
danger zone: shift the automatic transmis-
sion into position N.
XRelease the electric parking brake.
XRoll the vehicle to a safe place and park it
safely.
Get assistance from others if necessary.
iThe vehicle is locked automatically when
the ignition is switched on and the wheels are
turning. There is therefore a risk of being
locked out if the vehicle is being pushed or
tested on a dynamometer.
XSwitch the ignition off.
XShift the automatic transmission to park posi-
tion P(Ypage 170).
Depress the electric parking brake
(
Ypage 190).
Secure the vehicle against rolling away
(
Ypage 406).
XTo use the high-voltage switch-off device:
open the trunk lid.
XLift the trunk floor upwards (Ypage 329).
XRemove the right-hand paneling in the trunk.
XPress release clip :in the direction of the
arrow and pull it out.
XPull the high voltage switch-off device ;
apart until it engages in the stop position.
If the hybrid drive system has been deactivated
due to reasons mentioned above, have it checked at a qualified specialist workshop
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 (
Ypage 180).

Useful information
i
This Operator's Manual describes all models
and all standard and optional equipment of
your vehicle available at the time of publica-
tion of the Operator's Manual. Country-spe-
cific differences are possible. Please note
that your vehicle may not be equipped with all
features described. This also applies to
safety-related systems and functions.
iRead the information on qualified specialist
workshops (Ypage 28).
SmartKey
Important safety notes
GWARNING
If children are left unsupervised in the vehicle,
they could:
Ropen the doors, thus endangering other
people or road users.
Rget out and disrupt traffic.
Roperate the vehicle's equipment.
Additionally, children could set the vehicle in
motion if, for example, they:
Rrelease the parking brake.
Rshifting the automatic transmission out of
park position P
RStart the engine.
There is a risk of an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children or animals unattended in the
vehicle. Always keep the SmartKey out of
reach of children.
GWARNING
If you attach heavy or large objects to the
SmartKey, the SmartKey could be uninten-
tionally turned in the ignition lock. This could
cause the engine to be switched off. There is a risk of an accident.
Do not attach any heavy or large objects to theSmartKey. Remove any bulky key rings before
inserting the SmartKey into the ignition lock.
!Keep the SmartKey away from strong mag-
netic fields. Otherwise, the remote control
function could be affected.
Strong magnetic fields can occur in the vicin-
ity of powerful electrical installations.
Do not keep the SmartKey:
Rwith electronic devices, e.g. a mobile phone
or another SmartKey.
Rwith metallic objects, e.g. coins or metal foil.
Rinside metallic objects, e.g. a metal case.
This can affect the functionality of the Smart-
Key.
Do not keep the SmartKey in the temperature-
controlled cup holder (
Ypage 332). On vehicles
with the KEYLESS-GO start function, do not
keep it on the parcel shelf or in the trunk. Oth-
erwise, the SmartKey may not be detected, e.g. when starting the engine using the Start/Stop
button.
A check which periodically establishes a radio
connection between the vehicle and the Smart-
Key determines whether a valid SmartKey is in
the vehicle. This occurs, for example:
Rwhen starting the engine
Rwhilst driving
Rwhen using HANDS-FREE ACCESS
Rwhen the external door handles are touched

KEYLESS-GO
General notes
Bear in mind that the engine can be started by
any of the vehicle occupants if there is a Smart-
Key in the vehicle (
Ypage 164).
Locking/unlocking centrally
You can start, lock or unlock the vehicle using
KEYLESS-GO. To do this, you only need carry the
SmartKey with you. You can combine the func- tions of KEYLESS-GO with those of a conven-
tional SmartKey. Unlock the vehicle by using
KEYLESS-GO, for instance, and lock it using the
&
button on the SmartKey.
The driver's door and the door at which the han-
dle is used, must both be closed. The SmartKey
must be outside the vehicle. When locking or
unlocking with KEYLESS-GO, the distance
between the SmartKey and the corresponding
door handle must not be greater than 3 ft (1 m).
A brief radio connection between the vehicle
and the SmartKey determines whether a valid
SmartKey is in, or in the direct vicinity of, the
vehicle. This occurs, for example:
Rwhen starting the engine
Rwhile driving
Rwhen using HANDS-FREE ACCESS
Rwhen the external door handles are touched
Rduring convenience closing

a kicking movement under the bumper with your
foot.
Observe the following points:
RCarry your KEYLESS-GO key about your per-
son. The KEYLESS-GO key must be in the rear
detection range of the vehicle.
RWhen making the kicking movement, make
sure that you are standing firmly on the
ground and that there is sufficient clearance
to the rear of the vehicle. You could otherwise
lose your balance e.g. on ice.
RAlways ensure that you only make the kicking
movement within the detection range of sen-
sors
:.
RStand at least 12 in (30 cm) away from the
rear area while doing so.
RDo not come into contact with the bumper
while making the kicking movement. Other-
wise, the sensors may not function correctly.
RHANDS-FREE ACCESS does not function
when the engine is started.
RDirt caused by road salt around sensors :
may restrict functionality.
RUsing the HANDS-FREE ACCESS with a pros-
thetic leg may restrict functionality.
RIf a KEYLESS-GO key is within the rear detec-
