Wiper/Washer systemYou 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 7 briefly or
>use either the automatic windshield
washer 5 or the automatic intensive
washer 6.
To modify the sensitivity of the rain
sensor:
Turn rotary dial 7.
Turn the rain sensor off in auto-
matic car washes.
If you do not, damage may occur if the
wipers switch on unintentionally.< 2 Normal wiper speedThe wipers automatically revert to inter-
mittent operation when the vehicle is
stationary (not on vehicles with rain
sensor
*).
3 Fast wiper speedThe wipers automatically revert to nor-
mal speed when the vehicle is station-
ary (not on vehicles with rain sensor
*).
5 Automatic windshield washerThe system sprays washer fluid against
the windshield and activates the wipers
for a brief period.
If you only pull the lever briefly, the sys-
tem sprays washer fluid onto the wind-
shield without activating the wipers.6 Intensive automatic
cleaning unit
*
As in setting 5. In addition, an intensive-
action washer fluid is first sprayed on
the windshield.
For changing the wiper blades, refer to
page 166.
Headlamp washers
*
If they are on, the headlamps will also
be cleaned every fifth time you activate
the automatic windshield washer (inten-
sive-action or standard wash/wipe).
Do not use the washers if there is
any danger that the fluid will
freeze on the windshield, otherwise vi-
sion could be obscured. For this rea-
son, use an antifreeze agent. Refer to
page 148.
Do not use the washers when the reser-
voir is empty, since this could cause
damage to the washer pump. Windshield washer jetsThe windshield washer jets are warmed
automatically when the ignition key is in
position 2.

brake pedal
>When you apply pressure to the
clutch pedal, and when you move the
automatic transmission selector le-
ver from "Drive" to "Neutral"
>If you exceed or fall below the pro-
grammed speed for an extended pe-
riod (by depressing the accelerator,
for example).
To resume the stored settingPress button 3:
The vehicle accelerates to and main-
tains the last speed stored. When you
turn the ignition key to position 0, the
stored speed is deleted from the sys-
tem's memory and the system is deacti-
vated.To deactivate the systemWhen the cruise control has been can-
celed, press button 4 again. The indica-
tor lamp goes off and the memorized
speed is canceled.Do not use cruise control on twist-
ing roads, when high traffic den-
sity prevents driving at a constant
speed, when the road surface is slick
(snow, rain, ice), or when the road sur-
face is loose (rocks or gravel, sand).<

Onboard computerMode selectionFrom ignition key position 1 and up, you
can call up information from the on-
board computer using the button in the
turn signal lever. By pressing the button
briefly in the direction of the steering
column, you can call up a new function
for display.
The displays appear in the following
order: Outside temperature, average
fuel consumption, cruising range, aver-
age speed.
Starting with ignition key position 1, the
last active setting is displayed.
The range of available displays varies
according to your individual car's
equipment.390de336
Outside temperature and
average fuel consumptionYou can change the units of measure
(6/7) for the outside temperature dis-
play by
1 pressing and holding the trip odome-
ter reset button (in ignition key posi-
tion 1)
2 and then turning the ignition key to 0.
Refer also to page 82.390us126
Operating range and
average speed The computer bases its calculations of
the cruising range on the rate of fuel
consumption in the period immediately
preceding your data request.
The computer ignores any time spent
with the vehicle stationary and the
engine off in its average speed calcula-
tions.390us703

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).<

Tire Pressure Control (RDC)
*
The concept RDC monitors the tire pressures at all
four wheels, even when the vehicle is
moving. The system provides an alert
whenever the inflation pressure drops
significantly below the specified pres-
sure in one or more tires.
In order for the system to "learn" the
correct tire inflation pressure, check the
inflation pressure in all tires. Refer to
the table of "Tire inflation pressures"
beginning on page 29 and make any
necessary corrections. Then activate
the system.
This indicator lamp in the in-
strument cluster or the Check
Control will inform you if the tire
pressure is not correct.
Activate the system1 Turn the ignition key to position 2 (do
not start the engine).
2 Press and hold the button (arrow) un-
til the yellow indicator lamp in the in-
strument cluster comes on for a few
seconds or the message "SET TIRE
PRESSURE" appears in the Check
Control.
3 After you have driven for a few min-
utes, the RDC will import the current
inflation pressure in the tires as the
target values which the system will
monitor.
You will only have to repeat this proce-
dure if the tire inflation pressure must
be corrected. Otherwise, the RDC func-
tions automatically when the ignition
key is in position 2, and thus operates
whenever the vehicle is driven.390de320
Loss of tire pressureIf, after a certain period of time, the air
pressure has gone down significantly
(which is normal for any tire), the yellow
indicator lamp comes on or the mes-
sage "CHECK TIRE PRESSURE" ap-
pears in the Check Control.
This alerts you that you should have the
tires inflated to the specified pressures
as soon as possible.
If you are prompted to check the
tire pressure shortly after a cor-
rection has been made, this indicates
that the corrected values were not ac-
curate. Please check the inflation pres-
sure again and make corrections ac-
cording to the inflation pressure table.<
