Key/remote control
1Remote controls with integrated key.
They specify the functions of the Key
Memory. Individual functions of your
vehicle may behave differently depend-
ing on the remote control used.
To differentiate, you can mark the
remote controls using the color-coded
decals you received on taking delivery
of the vehicle
There is an extended-life battery
in every remote control which is
charged automatically in the ignition
lock as you drive.
If you have any remote control units that
are not being used on a regular basis,
you should therefore remember to
recharge these units by using them to
drive the vehicle for an extended period
at least once every six months, also
refer to page 36.
With Comfort Access, there is a battery
in every remote control. For instructions
on changing batteries, refer to
page37.<

such as in your wallet. This key is not

The adapter can be used to store the
spare key. It can be stored in the place
provided within the luggage compart-
ment lid-mounted onboard tool kit to
ensure that it will always be available,
refer to page201. You can find more
detailed information on using the
adapter in the section Using the spare

If you lock the storage compartment and
only turn over the remote control, no
access is possible via the luggage com-
partment lid. This is an advantage in a

closed. This simultaneously engages and
releases the locks on the following:
>Doors
>Luggage compartment lid
>Fuel filler door.
The central locking system can be oper-
ated from the outside
>via the remote control
>via the driver's door lock
>with Comfort Access via the door
handle
and from inside via the button for the cen-
tral locking system.
When the system is locked from inside, the
fuel filler door remains unlocked. Refer to
page38.
The anti-theft system is automatically acti-
vated whenever you activate the central
locking system from outside the vehicle.
The alarm system is armed/disarmed at the
same time.In an accident, the central locking system
automatically unlocks the vehicle. In addi-
tion, the hazard warning flashers and inte-
rior lamps switch on.

Using remote control
When you engage/release the vehicle's
locks, you simultaneously activate/deacti-
vate the anti-theft system, arm/disarm the
alarm system
and switch the interior lamps

In addition, the remote control offers you
another function:
>Panic mode
In case of danger, you can trigger an
alarm.

Alarm system
The concept
The vehicle alarm system responds:
>When a door, the hood, or the luggage
compartment lid is opened
>To movement in the vehicle interior:
interior motion sensor
>To changing the vehicle's tilt if someone
attempts to steal the wheels or tow the
vehicle
>To interruption of battery voltage.
The system responds to unauthorized vehi-
cle entry and attempted theft by simulta-
neously activating:
>An acoustic alarm, which lasts for a
period of approx. 30 seconds
>The hazard warning flashers for approx.
five minutes
>The high beams, which flash on and off
in the same rhythm.
Arming and disarming alarm system
When you lock or unlock the vehicle, either
with the remote control or at the door lock,
the alarm system is armed or disarmed at
the same time.
The system indicates that it has been cor-
rectly armed by switching on the hazard
warning flashers for a single cycle and by
emitting an acoustic signal.You can have different acknowledg-
ment signals set to confirm arming
and disarming.<
You can also open the luggage compart-
ment lid with the system armed using
button3on the remote control, refer
to page36. When you close the lid, the sys-
tem is rearmed.

Pressing the 'Panic mode' button for a
longer period also triggers the alarm, refer
to page36.<

Tilt alarm sensor and interior motion
sensor
Tilt alarm sensor
The tilt of the vehicle is monitored. The
alarm system reacts, e.g. in case of an
attempted wheel theft or towing.
Interior motion sensor
In order for the interior motion sensor to
function properly, the windows and glass
roof must be completely closed.
Avoiding unintentional alarms
The tilt alarm sensor and interior motion
sensor may be switched off at the same
time. This prevents unintentional alarms,
e.g. in the following situations:
>In duplex garages
>When transporting on car-carrying
trains
>When animals are to remain in the
vehicle.
Switching off tilt alarm sensor and
interior motion sensor
Press button 2on the remote
control twice consecutively.
The indicator lamp lights up briefly and then
flashes continuously. The tilt alarm sensor
and the interior motion sensor are switched
off up to the next unlocking and locking
actions. If you wish, the tilt alarm sensor and
interior motion sensor will be perma-
nently deactivated. Please contact your
BMW center for assistance.<
