Fuel specifications Tire inflation pressure The engine uses lead-free gasoline
only.
Required fuel:
>Premium Unleaded Gasoline,
min. 91 AKI.
AKI = Anti Knock Index
Do not use leaded fuels. The use
of leaded fuels will cause perma-
nent damage to the system's oxygen
sensor and the catalytic converter.<
Proper inflation pressures are on a
sticker attached to the B-pillar and
visible with the driver's door open.Check tire pressuresOn the next page you will find all the tire
pressure and ambient air temperature
specifications stated in the units usually
used in your country (psi; kilopascal).
For vehicles with Tire Pressure Control
(RDC):
After a correction of the tire inflation
pressure, reactivate the system. Refer
to page 86.460de163
Check tire inflation pressures Ð
including the space-saver spare
tire, or spare tire Ð regularly, at least
every two weeks and before beginning
a longer trip. Incorrect tire pressure can
otherwise lead to tire damage and acci-
dents.
Inflate the spare tire to the highest tire
inflation pressure specified for your
vehicle.<

Alarm system
*
The conceptThe vehicle's alarm system responds:
>When a door, the hood or the
luggage compartment lid is opened.
>To movement inside the vehicle
(interior motion sensor).
>To a change of the vehicle's tilt Ð if
someone attempts to steal the wheels
or tow the vehicle without authoriza-
tion, for example.
>If there is an 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 acti-
vated 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
by using a key or with the remote
control, the alarm system is also simul-
taneously armed or disarmed.
The interior motion sensor and the tilt
alarm sensor are activated approx.
30 seconds after you have finished
locking the vehicle.
If the alarm system has been armed
correctly, the hazard warning flashers
flash once.
You can have a signal set as
acknowledgment for both acti-
vating and deactivating the alarm.<
You can also open the luggage
compartment lid when the system is
armed by pressing button 3 of the
remote control (refer to page 37). When
it is closed, the lid is once again
secured.
Indicator lamp displaysThe indicator lamp is located under the
interior rearview mirror.
>When the indicator lamp flashes
continuously: the system is armed.
>If the indicator lamp flashes during
arming of the system: the door(s), the
hood or luggage compartment lid 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.
However, the interior motion sensor
is not activated.
>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 armed.463us010

Alarm system
*
>If the indicator lamp flashes for
10 seconds when the system is
disarmed: an attempted entry has
been detected in the period since the
system was armed.
Following triggering of an alarm, the
indicator lamp will flash continuously.Avoiding an unintentional alarmThe tilt alarm sensor and interior motion
sensor may be switched off at the same
time. You can do this to prevent a false
alarm from being triggered (in garages
with elevator ramps, for instance), or
when the vehicle is transported by
trailer or train:
Lock the vehicle twice (= arm the
system). Press button 2 on the remote
control twice in succession or lock the
vehicle twice with the key (refer to
page 36).
The indicator lamp lights up briefly and
then flashes continuously. The tilt alarm
sensor and the interior motion sensor
are deactivated as long as the system is
armed.
Activate the alarm to reactivate the tilt
alarm sensor and the interior motion
sensor.
Interior motion sensorThe transmitter and receiver of the inte-
rior motion sensor are located in a trim
panel in the vehicle's roof.
In order for the interior motion sensor to
function properly, the windows and
sliding/tilt sunroof must be completely
closed.
However, you should switch off the inte-
rior motion sensor (see previous column
under the heading "Avoiding an unin-
tentional alarm") if you wish to leave the
windows or sliding/tilt sunroof open.460de159

Wiper/Washer system1 Intermittent mode or rain
sensor
*
Intermittent mode:
You can use rotary dial 6 to select from
four wipe intervals.
In addition, the wipe interval automati-
cally adapts to variations in road speed.
Rain sensor:
The rain sensor is positioned on the
windshield, directly ahead of the inte-
rior rearview mirror. When the rain
sensor is activated, the windshield
wiper is controlled automatically,
depending on the degree of wetness of
the windshield (in both snow and rain).
You do not have to be concerned with
switching the windshield wiper on or off
or adjusting the wipe interval between
intermittent and full wipe. Instead, you 460de023
can concentrate fully on the traffic
conditions. This is especially important
under adverse weather conditions.
To activate the rain sensor:
In ignition key position 1, move the
lever to position 1. The wipers travel
once across the windshield, regardless
of the weather.
You can leave the lever permanently in
position 1, and then activate the rain
sensor from ignition key position 1. To
do this,
>turn rotary dial 6 briefly or
>use cleaning windshield 5.
To adjust the sensitivity of the rain
sensor:
Turn rotary dial 6.
Deactivating the rain sensor:
Put lever in position 0.
Turn the rain sensor off when
passing through an automatic car
wash. Failure to do so could result in
damage caused by undesired wiper
activation.<
2 Normal wiper speedWhen the vehicle is stationary, the
wipers switch automatically to intermit-
tent wipe (not on vehicles with rain
sensor).3 Fast wiper speedWhen the vehicle is stationary, the
wipers operate at normal speed (not on
vehicles with rain sensor).5 Cleaning windshieldThe system sprays washer fluid against
the windshield and activates the wipers
for a brief period.
If you pull the lever only briefly, the
system sprays washer fluid onto the
windshield without activating the
wipers.

The conceptThe PDC assists you when you back
into a parking space. A signal warns
you of the distance to an obstacle. To
do this, four ultrasonic sensors in the
rear bumper measure the distance to
the nearest object. The monitoring
range of the two corner sensors
extends to approx. 2 feet (60 cm)
behind the bumper. The two center
sensors cover a distance of approx.
4.9 feet (1.50 meters).
The system starts to operate automati-
cally about one second after you select
reverse with the ignition key in position 2.
PDC is deactivated when you shift back
out of reverse.
Acoustical signalsThe distance to the nearest object is
indicated by a tone sounding at various
intervals. As the distance between
vehicle and object decreases, the inter-
vals between the tones become
shorter. A continuous warning tone
sounds if the distance to a recognized
object is less than 1 foot (30 cm).
The warning signal is canceled after
approx. three seconds if the distance to
the obstacle 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 refer the problem to your
BMW center.The PDC does not remove the
driver's personal responsibility for
evaluating the distance between the
vehicle and any obstacles. Even when
sensors are involved, there is a blind
spot in which objects cannot be
detected. This applies especially in
those cases where the system
approaches the physical limits of ultra-
sonic measurement, 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 effec-
tively.
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).<
