The key set
1Master keys with remote control.
They specify the functions of the Key
Memory. In the process individual func-
tions of your vehicle can behave differ-
ently depending on the key used, see
further below.
To differentiate, you can mark the keys
with remote controls using the color-
coded decals you received on taking
delivery of the vehicle
There is an extended-life battery
in every master key with remote
control which is charged automatically
in the ignition lock as you drive.
If you have any master keys with remote
control that are not 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 every six months, also
refer to page 28.<
2Spare key for storage in a safe place,
such as in your wallet.
The locks for the luggage compartment
lid and the hotel function, refer to
page 30, cannot be operated with this
key. This is an advantage in a hotel, for
example. The key is not intended for
constant use
Replacement keys
Additional or replacement keys are avail-
able at your BMW center.
Key Memory
How the system functions
Doubtless you have often reflected on how
great it would be if you could configure
your vehicle's various adjustment settings
to meet your own personal requirements.
BMW has designed several freely select-
able options into the vehicle during its
development. You can set these as desired
via the Control Center.
You can have up to four different basic set-
tings adjusted for four different persons for
the specific keys. The only requirement is
that each person uses his or her own mas-
ter key with remote control.
When your vehicle is unlocked with the
remote control, the vehicle recognizes the
individual key by means of a data exchange
and makes adjustments accordingly.
Examples of Key Memory functions
>Automatic adjustment of the driver's
seat
>Locking the vehicle after moving off
>When unlocking with the remote con-
trol, either unlock only the driver's door
or the entire vehicle
>Activating visual warning for PDC Park
Distance Control
>Resetting volume setting.
Central locking system
The concept
The central locking system is ready for
operation whenever the driver's door is
closed. This simultaneously engages and
releases the locks on the following:
>Doors
>Compartment in the front center con-
sole

>Luggage compartment lid
>Fuel filler door.
The central locking system can be oper-
ated from the outside
>via the remote control
>via the door lock
and from inside via the button for the cen-
tral locking system.
If operated from the inside, the fuel filler
door and the compartment in the front
center console are not locked, refer to
page 29.
The anti-theft system is automatically acti-
vated whenever you activate the central
locking system from outside the vehicle.
It prevents the doors from being unlocked
using the safety lock buttons or door han-
dles. The alarm system is armed/disarmed
at the same time.
In the event of an accident, the central
locking system unlocks automatically. The
hazard warning flashers and interior lamps
also switch on.
Opening and closing: from
outside
Using the remote control
When you lock/unlock the vehicle, you
simultaneously activate/deactivate the
anti-theft system, arm/disarm the alarm
system, and switch the interior lamps on/
off.
Protect the remote control against
unauthorized use by handing over
only the spare key, for example when using
hotel valet parking.<
You can find more detailed information on
the alarm system on page 32.
Because any persons or animals left
unattended in a parked vehicle could
lock the doors from the inside, you should
always keep the remote control with you;
this precaution ensures that you will remain
able to unlock the vehicle from the outside
at all times.<

ever the need arises.<
Hotel function
The hotel function locks the compartment
in the front center console and the luggage
compartment lid individually and discon-
nects them from the central locking sys-
tem. The spare key, refer to page 26, does not fit the lock for the hotel function. If you
then only hand over the spare key, e.g. in a
hotel, no access is possible to the luggage
compartment lid or to the compartment in
the front center console.
Turn the key to the right, refer to illustration,
and remove.
The hotel function is only activated after
subsequent locking or unlocking of the
vehicle. This locks the luggage compart-
ment lid and the compartment in the front
center console and disconnects them from
the central locking system.
In the event of an electrical
malfunction
For manual unlocking, turn the master key
all the way to the right:
The compartment in the front center con-
sole is unlocked.
If unlocking was manual, the lock has
to be returned to the home position,
i.e. all the way back to the left, before set-
ting the hotel function again.<

swings to the rear and upwards when

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 of the vehicle's tilt if some-
one 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.
5 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 also open the luggage compart-
ment lid with the system armed using but-
ton on the remote control, refer to
page 28. When you close the lid, it is
secured again.
Switching off alarm
>Unlock the vehicle using the remote
control, refer to page 27
>or turn the ignition key to position 1.
