Alarm systemThe conceptThe vehicle alarm system responds:
>When a door, the hood or the lug-
gage compartment lid/tailgate is
opened
>To movement inside the vehicle
(interior motion sensor)
>To variations in the vehicle tilt sensor
such as occur 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:
>Sounding an acoustical alarm for
30 seconds
>The hazard warning flashers are
activated for approx. five minutes
>The high beams flash on and off in
the same rhythm.
To activate and deactivate the
alarm systemWhen the vehicle is locked or unlocked
with the key or the remote control, the
alarm system is also simultaneously
armed or disarmed.
The interior motion sensor is activated
approx. 30 seconds after you have fin-
ished locking the car.
The system indicates that it has been
correctly armed by switching on the
hazard flashers for a single cycle and by
emitting an acoustical signal.
You can have different acknowl-
edgment messages set to confirm
arming and disarming (not released at
this time).<
When the system is active, you can still
gain access to the luggage compart-
ment by pressing button 3 on the
remote control transmitter (refer to
page 39). When you close the luggage
compartment lid/tailgate, it locks again.
Indicator lamp displays>The indicator lamp below the interior
rearview mirror flashes continuously:
The system is armed
>The indicator lamp flashes during
arming: Door(s), the hood or luggage
compartment lid/tailgate are not
completely closed. Even if you do not
close the alerted area, the system be-
gins to monitor the remaining areas,
and the indicator lamp flashes contin-
uously after 10 seconds. However,
the interior motion sensor is not acti-
vated
>If the indicator lamp goes out when
the system is disarmed: No manipula-
tion or attempted intrusions have
been detected in the period since the
system was armed390de020

Sliding/Tilt sunroof
*
Other automatic operations are:
>With the sunroof open, press the
switch briefly toward "Lift:" The sun-
roof automatically extends to its fully
raised position
>With the sunroof lifted, press the
switch briefly toward "Open:" The
sunroof automatically opens all the
way.
Pressing the switch again briefly stops
the motion.Safety featureIf the sliding/tilt sunroof encounters re-
sistance at a point roughly past the
middle of its travel when it is closing,
the closing cycle is interrupted and the
sliding/tilt sunroof will open again
slightly.
Despite this safety feature, be ex-
tremely careful that the closing
path of the sunroof is not obstructed
whenever it is closed. Otherwise, trig-
gering the closing-force limitation may
not be ensured in some situations (with
very thin objects, for instance). You can
override this safety feature by pressing
the switch beyond the resistance point
and holding it.<
Sliding/Tilt sunroof with glass
moonroof
*
The options and control procedures are
essentially the same as those previ-
ously described for the sliding/tilt sun-
roof. In order to open the raised roof,
press the control switch towards
"Open" until the roof has reached the
desired position.
The headliner insert slides back some-
what when you raise the sunroof. When
the sunroof is opened the headliner
retracts with it. The headliner will then
automatically remain in its retracted
position, but can be repositioned as
desired.
Power loss or malfunctionAfter interruptions in the electrical
supply (when the battery is discon-
nected, for instance), the sunroof may
only lift. To reinitialize the mechanism:
1 Raise the sliding/tilt sunroof all
the way
2 Press and hold the switch for
approximately twenty seconds.
In the event of an electrical malfunction,
you can also operate the sliding/tilt sun-
roof manually. Refer to page 180.390de637

Mirrors
The mirror on the passenger's
side features a lens with a more
convex surface than the mirror installed
on the driver's side. When estimating
the distance between yourself and
other traffic, bear in mind that the ob-
jects reflected in the mirror are closer
than they appear. This means that esti-
mations of the distance to following
traffic should not be regarded as pre-
cise.<
Electric heatersBoth mirrors are heated automatically
with the ignition key in position 2.
Interior rearview mirrorTo reduce glare from vehicles behind
you after dark, tilt the mirror by moving
the small lever.Lighted vanity mirrorFold down the sun visor and slide the
cover panel to the side as required.
The mirror lamps operate in ignition key
positions 1 and 2.Sun visorsThese can be folded down toward the
windshield or swiveled out against the
side windows.390de030
Interior rearview mirror with
automatic dimming feature
*
By responding to the effects of ambient
light and the glare from following traffic,
this mirror automatically dims through
an infinitely-variable range.
The mirror automatically reverts to its
clear, undimmed setting whenever you
select "Reverse."
For proper functioning of the mirror, be
sure that the two photocells are unob-
structed and clean. One of the photo-
cells (arrow) is positioned in the mirror's
glass, while the other is slightly offset
on the opposite side of the mirror.
For an explanation of the electro-chro-
mic technology used in this mirror, refer
to page 192.390de031

Automatic transmission
*
Electronic transmission control
module
If the indicator lamp comes on
or if the message "TRANS.
FAILSAFE PROG" appears in
the Check Control
*, there is a malfunc-
tion in the transmission system.
Bring the vehicle to a stop, select the
"Park" position, apply the parking brake
and shut the engine off (ignition key po-
sition 0). Restart the engine after a few
seconds. If the indicator lamp goes out
again after a few seconds, the normal
transmission functions have been re-
stored. You may continue to drive as
usual.
If the indicator lamp does not go out,
you can place the selector lever in all
positions. However, the vehicle will now
only drive forward with limited gear
selection.
Under these circumstances, avoid ex-
treme engine loads and consult the
nearest authorized BMW center.
Do not work in the engine com-
partment when a drive gear (for-
ward or reverse) is engaged. If you do
this, the vehicle could move.<
For jump-starting, towing and tow-
starting, refer to pages 182 and 183.

Automatic transmission with Steptronic
*
Upshifts or downshifts will be carried
out by the ATC only at appropriate en-
gine speeds and road speeds. For in-
stance, if engine speed is too high, a
downshift will not be executed. The
gear selected will appear briefly in the
instrument cluster followed by the cur-
rent gear.
If you are driving in the manual
mode and wish to accelerate rap-
idly from low road speeds (when pass-
ing, for instance), you must shift down
manually or with the kickdown func-
tion.<
You can only change from "M/S" to se-
lector lever positions "P,""R," and "N"
via the "D" position.
In the following situations, the Step-
tronic "thinks" for you in the manual
mode:
>In order to prevent engine over-
speeding, the transmission shifts au-
tomatically to the next higher gear
shortly before the RPM cutoff point
>At low speeds, the transmission shifts
down automatically Ð you do not have
to act
>In the kickdown mode, the transmis-
sion shifts down to the lowest gear
which is possible, depending on the
engine speed
>According to the situation, for
instance in wintry conditions, the
vehicle can be started in 2nd or
3rd gear.Electronic transmission control
module
If the indicator lamp comes on
or the message "TRANS.FAIL-
SAFE PROG" appears in the
Check Control
*, there is a fault in the
transmission system.
Bring the vehicle to a stop. Move the
transmission selector lever to "P." Set
the parking brake and turn the engine
off (ignition key to position 0).
Wait a few seconds, then start the
engine.
If the indicator lamp goes out after a
few seconds, normal transmission per-
formance has been restored. You may
continue to drive as usual. If the indica-
tor lamp does not go out, you can place
the selector lever in all positions. How-
ever, the vehicle will now only drive for-
ward with limited gear selection.
If this happens, avoid extreme engine
loads and consult the nearest autho-
rized BMW center.
Do not work in the engine com-
partment when a drive gear (for-
ward or reverse) is engaged. If you do
this, the vehicle could move.<
For jump-starting, towing and tow-
starting, refer to pages 182 and 183.

The PDC assists you when you are
parking. A signal warns you of the real
distance to an obstacle. To do this, four
ultrasonic sensors in the rear bumper
measure the distance from the nearest
object. The monitoring range for the
two corner sensors ends approx. 2 feet
(60 cm) beyond the respective bumper.
The range of the two middle sensors is
approx. 4.9 feet (1.50 meters) outward.
The system starts to operate automati-
cally about one second after you select
reverse with the ignition key in posi-
tion 2. It is similarly deactivated when
you engage reverse gear or move the
selector lever position from the "R" po-
sition.
Acoustical signalsThe distance to the nearest object is in-
dicated by a tone sounding at various
intervals. As the distance between vehi-
cle and object decreases, the intervals
between the tones become shorter. A
continuous tone indicates the presence
of an object less than 1 ft. (30 cm)
away.
The warning signal will be canceled af-
ter approx. 3 seconds if the distance to
the obstruction remains constant during
this time (if you are moving parallel to a
wall, for instance).
System malfunctions will be indicated
by a continuous high-pitched tone
when the system is activated the first
time. Please have the cause checked
and corrected by your authorized BMW
center.The PDC does not remove the
driver's personal responsibility for
evaluating the distance between the ve-
hicle and any obstacles. Even when
sensors are involved, there is a blind
spot in which objects cannot be de-
tected. This applies especially in those
cases where the system approaches
the physical limits of ultrasonic mea-
surement, as occurs with tow bars and
trailer couplings, and in the vicinity of
thin and painted objects.
Certain sources of sound, such as a
loud radio, could drown the PDC signal
tone.<
Keep the sensors clean and free
of ice or snow in order to ensure
that they continue to operate effectively.
Do not apply high pressure spray to the
sensors for a prolonged period of time.
Maintain an adequate distance of more
than approx. 4 inches (10 cm).<
