Opening and closing Ð via the remote controlThe conceptThe remote control gives you an excep-
tionally convenient method for
unlocking and locking your vehicle.
Furthermore, it provides two additional
functions which you can only execute
via the remote control:
>To switch on interior lamps, refer to
page 30.
With this function, you can also
search for the vehicle, when parked
in an underground garage, for
instance
>To open the luggage compartment
lid, refer to page 30.
The luggage compartment lid will
open slightly, regardless of whether it
was previously locked or unlocked.
Whenever you unlock (lock) the vehicle,
you simultaneously deactivate (activate)
the anti-theft system, disarm (arm) the
alarm system and switch the interior
lamps on (off).
You can have a signal set to
confirm that the vehicle's locks
have engaged securely.<
Since children might be able to
lock the doors from the inside,
always take the vehicle keys with you
so that the vehicle can be opened again
from the outside at any time.<
If it is no longer possible to lock
the vehicle via the remote control,
the battery is discharged. Use this key
while driving for an extended period in
order to recharge the battery.
To prevent unauthorized use of the
remote control, for example surrender
only the door and ignition key or the
spare key when leaving the vehicle for
valet parking, refer to page 28.
In the event of a system malfunction,
please contact your BMW center. You
can also obtain replacement keys
there.<

Alarm system
*
The conceptThe vehicle alarm system responds:
>When a door, the hood or the
luggage compartment lid is opened
>To movement inside the vehicle (inte-
rior motion sensor)
>To variations in the vehicle's tilt angle
such as those occurring during
attempts to steal the wheels or tow
the vehicle
>To interruption of battery voltage.
The system responds to unauthorized
vehicle entry and attempted theft by
simultaneously activating the following:
>The acoustic alarm sounds for
30 seconds
>The hazard warning flashers are acti-
vated for approx. five minutes
>The high beams flash on and off in
rhythm with the hazard warning
flashers.
To arm and disarm the
alarm systemWhen the vehicle is locked or unlocked
via the driver's door lock or with the
remote control, the alarm system is also
simultaneously armed or disarmed.
You can have different acknowl-
edgment signals set to confirm
arming and disarming.<
You can open the luggage compart-
ment lid even when the system is
armed by pressing the button on the
remote control, refer to page 30. When
it is closed, the lid is once again
secured.
Indicator lamp displays>The indicator lamp below the interior
rearview mirror flashes continuously:
the system is armed
>The indicator lamp flashes while the
system is armed: the door(s), the
hood or luggage compartment lid are
not completely closed. Even if you do
not close the alerted area(s), the
remaining areas are secured, and the
indicator lamp will flash continuously
after 10 seconds. However, the inte-
rior motion sensor is not activated

Transporting children safelyLATCH child-restraint mounting
system
*
Remove the cover from the outside
mount by pulling forward. When re-
installing ensure that the recess is on
the top.
Tilt the backrest halfway forward to
make the cover easier to remove (refer
to page 91).
The illustration is an example showing
the mounts for a LATCH child-restraint
mounting system at the right rear.
Always follow all manufacturer's
instructions and observe all safety
precautions when installing the LATCH
child-restraint mounting system.<
Commercially available child seats
complying with the legal standard are
designed to be secured with a lap belt
or with the lap belt portion of a combi-
nation lap/shoulder belt.
Improperly or inadequately installed
restraint systems can increase the risk
of injury to children. Always read and
follow the instructions that come with
the system.
If you use a child-restraint system with
a tether strap, three additional tether
anchorage points (refer to the arrows in
the illustration) have been provided.
Depending on the location selected for
seating in the rear passenger area,
attach the tether strap to the corre-
sponding anchorage point to secure the
child-restraint system. Remove the
center cover first.
If the selected seating position is fitted
with a headrest lift the headrest and
pass the tether strap between the
headrest and the backrest.
Adjust the tether strap according to the
child-restraint manufacturer's instruc-
tions.
Before installing any child-
restraint device or child seat,
please read the following:
Never install a rear-facing child-
restraint system in the front passenger
seat of this vehicle.
Your vehicle is equipped with an airbag
supplemental restraint system for the
front passenger. Because the backrest
on any rear-facing child-restraint
system (of the kind designed for infants
under 1 year and 20 lbs/9 kg) would be
within the airbag's deployment range,
you should never mount such a device
in the front passenger seat, as the
impact of the airbag against the child-
restraint's backrest could lead to
serious or fatal injuries.
If it is necessary for a child (not an
infant) to ride in the front seat, certain
precautions should be taken. First,
move the passenger seat as far away
from the instrument panel as possible.
This important precaution is intended to

52n
Transporting children safelymaximize the distance between the
airbag and the child. Older children
should be tightly secured with the
safety belt. Younger children should be
secured in an appropriate forward-
facing child-restraint system that has
first been properly installed with a
safety belt.
Never install a rear-facing child-
restraint system in the front passenger
seat. We strongly urge you to carefully
read and comply with the instructions
for installation and use provided by the
child-restraint's manufacturer whenever
you use such a device.
Always ensure that all occupants (of all
ages) remain properly and securely
restrained at all times.c
All rear seating positions in your vehicle
meet the recommendations of
SAE J1819, an industry recommended
standard for securing child-restraint
systems in motor vehicles.
Securing child-restraint systemAll of the rear belt retractors and the
front passenger's safety belt can be
locked for mounting and securing child-
restraint systems.
A label with the appropriate instructions
for this is located in the immediate
vicinity of the buckle latch of each
safety belt.
To lock the safety beltExtract the entire length of the belt from
the inertia reel mechanism. Allow the
reel to retract the belt somewhat and
engage the buckle, then tighten the belt
against the child-restraint system. The
retraction mechanism is now locked.
The belt cannot be extracted further.
Always observe the installation instruc-
tions provided by the manufacturer of
the child-restraint system.To release the safety beltTo release the safety belt, remove the
child's seat and retract the safety belt to
its end position on the belt retractor.

Automatic transmission with Steptronic
*
You can drive as with a normal auto-
matic transmission. In addition, you can
also shift manually.
When you move the selector lever from
the "D" position to the left into the M/S
range, the performance-oriented shift
programs of the automatic transmission
are engaged. Steptronic enters the
manual selection mode and executes
the desired shift whenever you tap the
selector lever in the direction indicated
by "+" or "Ð." Whenever you want to use
automatic again, just shift the selector
lever toward the right to position D.
Selector lever positions
P R N D M/S + Ð
Starting the engineThe engine can only be started in
selector lever positions P ("Park") or N
("Neutral").Range selectionA detent prevents inadvertent shifts to
the "Reverse" or "Park" selector lever
positions. To disengage the detent,
press the button on the front side of
the shift knob (arrow).
While the vehicle is stationary and
before shifting out of "Park" or
"Neutral," depress the footbrake in
order to disengage the selector lever's
lock mechanism (Shiftlock).
Hold the footbrake down until starting
off. Otherwise the vehicle will "creep"
when a drive position is engaged.<
To prevent the vehicle from
starting off on its own, always
move the selector lever to position P
or N and engage the parking brake
before leaving your vehicle with the
engine running.
Do not leave the vehicle unattended
with the engine running. An unattended
vehicle with a running engine repre-
sents a potential safety hazard.<
