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.<

Luggage compartment
Net*
You can use the net to store smaller objects
on the bulkhead separating the luggage
compartment from the rear seats.
Do not stow objects behind the side
trim panels on the left and right in the
luggage compartment, as otherwise the

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.
Unlocking vie the door lock will trigger
the alarm on some national-market
versions.
Pressing the 'Panic mode' button for a
longer period also triggers the alarm, refer
to page36.<
Switching off alarm
>Unlock the vehicle using the remote
control, refer to page36
>or insert the remote control all the way
into the ignition lock, engaging the
detent.
Indicator lamp displays
>The indicator lamp below the interior
rearview mirror flashes continuously:

tailgate are not completely closed. Even
if you do not close the alerted area, the
system begins to monitor the remaining
areas, and the indicator lamp flashes
continuously after 10 seconds. How-
ever, the interior motion sensor is not
activated

The headliner insert slides back somewhat
when you raise the roof. When the roof is
opened the headliner retracts with it.
Do not use force to close the head-
liner insert with the roof in its raised
position, as damage to the mechanism
could result. When leaving the vehicle, dis-
engage the remote control in the ignition
lock and close the doors, as otherwise chil-
dren could operate the roof and injure
themselves etc.<
For information on using the convenience
operation at the door lock or with the
remote control, refer to page36 or38.
Automatic* opening and closing
Briefly press the switch beyond the resis-
tance point and then release it.
In addition, the following response is also
automatic:
With the roof open, briefly press the switch
in the 'Raise' direction: the roof rises to its
tilt-up end position.
Press the switch again in any direction to
stop the roof.
Anti-trapping mechanism
If the glass roof meets with resistance dur-
ing closing from approximately the middle
of the roof opening or when closing from
the raised position, then the closing opera-
tion is interrupted and the glass roof opens
again somewhat.
Despite the anti-trapping mechanism
inspect the roof's travel path prior to
closing it, as the safety system might fail to
detect certain kinds of obstructions, such
as very thin objects, and the roof would
continue closing.
The protection provided by the anti-trap-
ping mechanism is limited when the switch
is pressed beyond the resistance point and
held. The roof only opens a short distance.
If you again press the switch beyond the
resistance point and hold it in position
within a period of roughly 2 seconds, the
anti-trapping mechanism will be deacti-
vated.< When you close the glass roof, it will
slow down as it approaches the end
of its travel path; this is to allow the safety
feature to respond more precisely to any
obstructions encountered in this critical
range.<
Following interruptions in electrical
power supply
Following interruptions in electrical power,
for instance, when the battery is discon-
nected, it is possible that the glass roof will
extend to its tilt-up position, but fail to
respond to other commands. The system
must be initialized. BMW recommends hav-
in g t h is w o rk car r ied ou t b y y ou r B MW c en -
ter.
Malfunction
In the event of an electrical defect, you can
operate the glass roof manually:
1.Take out the interior lamp, reach behind
the opening, press out the cover
2.Insert the Allen wrench supplied with
the onboard tool kit, refer to page201,
in the opening provided. Turn to slide
the glass roof in the desired direction.

66 Provided that the remote control is
inserted in the ignition lock, you can
also release the parking brake manually
after the engine has been switched off,
refer to page64. This function is useful in
automatic car washes, etc.
Automatic Hold is deactivated.<
When leaving the vehicle, always
release the remote control from the
detent in the ignition lock; this precaution
prevents children from disengaging the
parking brake, etc.<
For your safety
Automatic Hold is automatically deacti-
vated when
>the engine is switched off
>the system detects that the driver's seat
is not occupied while the engine is run-
ning
>the hood is opened while the engine is
running
>the luggage compartment is opened
with the transmission in position R while
the engine is running, and
>when the parking brake is used to bring
the vehicle to a stop.

green to red, and the AUTO P letters in the
Info Display disappear.
Before starting off again, briefly press the
button to disengage the parking brake
manually, refer to page64, or reactivate
Automatic Hold, refer to page65.
Before leaving the vehicle with the
engine running, always move the
automatic transmission's selector lever to
position P and ensure that the parking
brake is engaged. The vehicle could start to
roll if you fail to observe these precautions.
Never leave an unattended vehicle with the
engine running, as such a vehicle repre-
sents a potential safety hazard.<
Automatic Hold is automatically deac-
tivated whenever the system detects
any tendency for the wheels to spin in
response to slippery road surfaces. Note the status reports in the Check Control.
You can find additional information on the
Check Control on page83.<
Malfunction
If a malfunction occurs, the indicator
lamp lights up yellow in the Info Dis-
play and a status report will appear in the
Check Control. Please note any supple-
mentary information that appears on the
Control Display.
Releasing parking brake manually
You can respond to any interruptions in the
supply of electrical power, for instance, if
the battery is discharged or disconnected,
by releasing the parking brake manually.
Before proceeding to release the
parking brake manually, and each
time you park the vehicle without engaging
the parking brake, always ensure that the
automatic transmission's selector lever is in
position P, refer to page68. Note the range
indicated in the Info Display.
If the wheel must be changed on a surface
with a more severe slope, take additional
precautions to secure the vehicle from roll-
ing e.g. with a chock, refer to page204
Otherwise there is a danger that the vehicle
could start to roll if parked on a steep
slope.<
Should it also be necessary to release the
automatic transmission's lockout manually,
for instance, if the battery is discharged,
always adhere to the following sequence:
1.If necessary, start by manually releasing
the parking brake
2.Then release the automatic transmis-
sion's lockout manually, refer to

ing wheel are touched, the transmission
upshifts. When the buttons on the front of
the steering wheel are touched, the trans-
mission downshifts. The Info Display shows
the manual ranges M1 through M6.
Upshifts and downshifts are executed only
when they will result in a plausible combi-
nation of engine and vehicle speed; thus,
for example, a downshift that would cause
the engine to overrev will not be executed
by the system. The selected gear appears
briefly in the Info Display, followed by the
current gear.
Pressing the S/M/D button again switches
into the Automatic program again, and D
appears in the program indicator of the Info
Display.
Malfunction

the selector lever to any desired position,
the transmission will revert to operation in
its default mode with only a limited number
of forward gears.
Have the system checked as soon as pos-
sible.
Jump-starting and towing, refer to
pages209 and210.
