Deactivate the hybrid system manually if: R
the u restraint system warning lamp in the
instrument cluster lights up after an accident R
the vehicle is badly damaged, e.g. after an
accident, and the restraint system compo-
nents were not activated R
the vehicle is badly damaged and has to be
towed or transported X
If possible, move the vehicle out of the
danger zone: shift the automatic transmis-
sion into position N .X
Release the electric parking brake. X
Roll the vehicle to a safe place and park it
safely.
Get assistance from others if necessary.
i The 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. X
Switch the ignition off. X
Shift the automatic transmission to park posi-
tion P ( Y
page 170).
Depress the electric parking brake
( Y
page 190).
Secure the vehicle against rolling away
( Y
page 406). X
To use the high-voltage switch-off device:
open the trunk lid. X
Lift the trunk floor upwards ( Y
page 329).X
Remove the right-hand paneling in the trunk.
X
Press release clip C in the direction of the
arrow and pull it out. X
Pull the high voltage switch-off device D
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
G WARNING
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.
G WARNING
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 ( Y
page 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.

workshops ( Y
page 28).
SmartKey
Important safety notes
G WARNING
If children are left unsupervised in the vehicle,
they could: R
open the doors, thus endangering other
people or road users. R
get out and disrupt traffic. R
operate the vehicle's equipment.
Additionally, children could set the vehicle in
motion if, for example, they: R
release the parking brake. R
shifting the automatic transmission out of
park position PR
Start 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.
G WARNING
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 the
SmartKey. 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: R
with electronic devices, e.g. a mobile phone
or another SmartKey. R
with metallic objects, e.g. coins or metal foil. R
inside 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 ( Y
page 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: R
when starting the engine R
whilst driving R
when using HANDS-FREE ACCESS R
when the external door handles are touched R
during convenience closing

You can also set an audible signal to confirm
that the vehicle has been locked. The audible
signal can be activated and deactivated via the
multimedia system; see the separate operating
instructions.
You will receive visual and acoustic locking con-
firmation if all components were able to be
locked.

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 ( Y
page 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
7 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: R
when starting the engine R
while driving R
when using HANDS-FREE ACCESS R
when the external door handles are touched R
during convenience closing
X
To unlock the vehicle: touch the inner sur-
face of the door handle. X
To lock the vehicle: touch sensor surface C
or D .
Make sure that you do not touch the inner
surface of the door handle. X
Convenience closing feature: touch
recessed sensor surface D for an extended
period.
Further information on the convenience clos-
ing feature ( Y
page 96). X
To unlock the trunk lid: pull the handle on
the trunk lid.
Deactivating and activating
If you do not intend to use a SmartKey for an
extended period of time, you can deactivate the
KEYLESS-GO function of the SmartKey. The
SmartKey will then use very little power, thereby80

especially if the vehicle is in motion. There is a
risk of poisoning.
Always switch off the engine before opening
the trunk lid. Never drive with the trunk lid
open.
