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 correcting the tire inflation pres-
sure, reactivate the system. Refer to
page 91.462de197
Check tire inflation pressures,
including the space-saver spare
tire, regularly, at least every two weeks
and before beginning any extended
driving. Otherwise, incorrect tire pres-
sure can lead to tire damage and acci-
dents.<

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
(interior motion sensor).
>To a change of the vehicle's tilt Ð if
someone attempts to steal the
wheels or tow the vehicle without
authorization, for example.
>If there is an interruption in battery
voltage.
The system responds to unauthorized
vehicle entry and attempted theft by
simultaneously activating the following:
>Sounding an 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 arming
and disarming the alarm system.<
You can also open the luggage
compartment lid when the system is
armed by pressing button 3 of the
remote control (refer to page 36). When
it is closed, the lid is once again
secured.
Indicator lamp displaysThe indicator lamp is located under the
interior rearview mirror.
>The indicator lamp flashes continu-
ously: the system is armed.
>The indicator lamp flashes while the
system is being 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 secure, and
the indicator lamp will flash continu-
ously after 10 seconds. However, the
interior motion sensor is not acti-
vated.
>The indicator lamp goes out when the
system is disarmed: no manipulation
or attempted intrusions have been
detected in the period since the
system was armed.46cus033

Alarm system
*
>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 unintentional alarms The 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 (= arm the system)
twice. Press button 2 on the remote
control twice in succession or lock the
vehicle twice with the key. Refer to
page 34.
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.
Reset the alarm to reactivate the tilt
alarm sensor and the interior motion
sensor.
Interior motion sensor Transmitter and receiver for the interior
motion sensor are located in the front
area of the center console, invisible to
the driver, and in the back area of the
center console under a rack.
However, be sure to deactivate the
interior motion sensor (see previous
column) if children or animals are to
remain in the vehicle.
For US owners onlyThe transmitter and receiver units
comply with part 15 of the FCC (Federal
Communication Commission) regula-
tions. Operation is governed by the
following:
FCC ID: LTQSDR2G5
Compliance statement:
This device complies with part 15 of the
FCC Rules. Operation is subject to the
following two conditions:
>This device may not cause harmful
interference, and
>this device must accept any interfer-
ence received, including interference
that may cause undesired operation.
Any unauthorized modifications to
these devices could void the
user's authority to operate the equip-
ment.<

Washer/Wiper 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 is varied
automatically depending on 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 on
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 46cde095
intermittent and full wipe. Instead, you
can concentrate fully on the traffic
conditions. This is especially important
under adverse weather conditions.
To activate the rain sensor:
From ignition key position 1 and up, you
can move the lever to position 1. The
wipers travel once across the wind-
shield, regardless of the weather.
You can leave the lever permanently in
position 1. It is then only necessary to
activate the rain sensor from ignition
key position 1 and up. 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 windshield The 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 range for the
sensors located at both rear corners
ends approx. 2 ft (60 cm) behind the
bumpers. The two center sensors
cover a distance of approx. 4.9 ft
(1.50 meters).
The system starts to operate automati-
cally about one second after you select
reverse with the ignition key in posi-
tion 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
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 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 subject the sensors to high-
pressure washers for a prolonged
period of time. Always maintain a
distance of more than 4 in (10 cm).<
