by approx. 0.6 mph (1 km/h) every time
you tap the button.
Press and hold button (Ð):
With the cruise control active, the
system automatically reduces the
throttle opening to slow the vehicle.
When you release the button, the
system registers and maintains the
current speed.
To interrupt the cruise controlWhen the system is activated, press the
button. The indicator lamp stays on.
You can use the cruise control again
whenever you want by calling up the
speed that was stored last.
In addition, cruise control is interrupted
automatically:
>When the brakes are applied
>When you apply pressure to the
clutch pedal, or when you move the
automatic transmission selector lever
from D to N
>If you exceed or fall below the
programmed speed for an extended
period (by depressing the acceler-
ator, for example).
To recall the stored settingPress button:
The vehicle accelerates to and main-
tains the last speed stored.

Fuel gauge Temperature gauge Service Interval DisplayOnce the indicator lamp stays on
continuously, there are still approx.
2 gallons (8 liters) of fuel in the fuel
tank.
For fuel tank capacity, refer to
page 135.
Certain operating conditions (such as
those encountered in mountainous
areas) may cause the needle to fluc-
tuate slightly.
Please refuel early, since driving
to the last drop of fuel can result in
damage to the engine and/or catalytic
converter.<
When you switch on the ignition, the
indicator lamp lights up briefly as an
operation check.
BlueThe engine is still cold. Drive at
moderate engine and vehicle speeds.RedWhen you switch on the ignition, the
warning lamp comes on briefly to
confirm that the system is operational.
If the lamp comes on during normal
vehicle operation: the engine has over-
heated. Stop and switch the engine off
immediately and allow it to cool down.
Checking coolant level, refer to
page 111.Between the blue and red zonesNormal operating range. The needle
may rise as far as the edge of the red
sector in normal operation.
Remaining distance to serviceThe displays shown in the illustration
appear for a few seconds when the
ignition key is in position 1 or after the
engine is started.
The next service due appears with the
message OIL SERVICE or INSPECTION,
together with the distance remaining in
miles (kilometers) before the next sched-
uled service.
The computer bases its calculations of
the remaining distance on the preceding
driving style.
A flashing message and a "Ð" in front of
the number mean that the service inter-
val has already been exceeded by the
distance shown on the display. Please
contact your BMW center for an
appointment.

Park Distance Control (PDC)
*
The conceptPDC provides extra safety and conve-
nience during parking maneuvers by
providing an acoustic signal to indicate
the distance between your front and
rear bumpers and the nearest object.
The monitoring range for the front and
two rear sensors extends outward
roughly 2 ft (60 cm), while the rear
bumper's two centrally located sensors
detect objects at distances of up to
approx. 4.9 ft (1.50 meters).
The system starts to operate automati-
cally approx. one second after you
select reverse or move the selector
lever into the "R" position with the igni-
tion key in position 2. PDC is deacti-
vated when you shift back out of
reverse.
Acoustic 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 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 or wedge-shaped
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 will continue to operate effec-
tively.
Do not apply high pressure spray to the
sensors for a prolonged period of time.
Always maintain a distance of more
than 4 in (10 cm).<

ASC+T Dynamic Stability Control (DSC)
*
Reactivating the ASC+TPress the button again; the indicator
lamp goes out.
The laws of physics cannot be
repealed, even with ASC+T. It will
always be the driver's responsibility to
drive in a manner that matches road
conditions. This is why you should not
use the additional safety margin the
system provides as an excuse to take
risks.<
The conceptDSC maintains vehicle stability, even in
critical driving situations.
The system optimizes vehicle stability
during acceleration and when starting
from a full stop, as well as optimizing
traction. In addition, it recognizes
unstable vehicle conditions, such as
under- or oversteering, and, within
physically feasible limits, helps keeping
the vehicle on a steady course by
reducing the engine speed and brake
applications to the individual wheels.
The DSC is operational every time you
start the engine. DSC incorporates the
ADB and CBC (Cornering Brake
Control) functions.
The Automatic Differential Brake (ADB)
relies on selective braking applications
at the drive wheels to furnish the func-
tionality of a conventional limited-slip
differential for enhanced traction in crit-
ical driving conditions such as those
encountered on snow-covered road
surfaces, etc.
The ADB is operational when DSC is
switched off.
Indicator lamp
The indicator lamp on the instru-
ment cluster will go out shortly
after the ignition has been
switched on, refer to pages 18, 19.
The indicator lamp flashes:
DSC controls the drive and braking
forces.
The indicator lamp stays lit:
DSC has been switched off with the
button; ADB is operational.
ADB control intervention is not indi-
cated.
The indicator and the brake
warning lamps will remain on
continuously:
The DSC, ADB and DBC have
been switched off with the
button or are defective.
The vehicle will remain completely
operational, however, without DSC. In
the event of a fault, please consult your
BMW center, refer to pages 18, 19.

Tire Pressure Monitor (RDC)
*
The conceptRDC monitors the tire pressures at all
four wheels while the vehicle is moving.
The system provides an alert whenever
the inflation pressure drops significantly
below the specified pressure in one or
more tires.
In order for the system to "learn" the
correct tire inflation pressure, check the
inflation pressures in all tires according
to the inflation pressure table on
page 25 and make corrections as
necessary. Then activate the system.
This indicator lamp in the instru-
ment cluster will inform you if
the tire pressure is not correct.
To activate the system1. Turn ignition key to position 2 (do not
start the engine)
2. Press the button long enough for the
yellow indicator lamp in the instru-
ment cluster to light up for a few
seconds
3. After a few minutes driving time,
RDC sets the current inflation pres-
sures in the tires as the target values
to be monitored.
You will only have to repeat this proce-
dure following a correction of the tire
inflation pressure. Otherwise, RDC
functions automatically when the igni-
tion key is in position 2, and thus oper-
ates whenever the vehicle is driven.
In the event of loss in inflation
pressureIf the inflation pressure has dropped
significantly over a long period of time
(which is normal for any tire), the yellow
indicator lamp will come on.
This alerts you to have the tires inflated
to the specified pressures as soon as
possible.
If you are prompted to check the
tire pressure shortly after a
correction has been made, this indi-
cates that the corrected values were
not accurate. Please check the inflation
pressure again and make corrections
according to the inflation pressure
table. Then activate the system once
again.<

Flat Tire Monitor
*
The conceptAs you drive, the Flat Tire Monitor
keeps track of pressure levels in all four
tires in order to detect and warn of any
substantial pressure loss.
The system actually detects pressure
loss by monitoring differences in the
relative speeds of the four wheels. It
interprets variations outside specified
limits as severe pressure loss, and then
responds by generating a warning.
Initializing the systemInitializing is necessary to familiarize the
system with the correct inflation pres-
sure.
Repeat this process after any changes
in tire inflation pressure, tire rotation or
replacement. Do not carry out further
system initialization after adjusting the
inflation pressure and letting the system
"learn" the correct pressures.
1. Check the tire inflation pressures in
all the tires, comparing them with the
inflation pressure chart on page 25
and adjusting their pressure if neces-
sary
2. Turn the ignition key to position 2
3. Press the button as long as you need
to until the indicator lamp on the
instrument cluster lights up. After a
little while, the indicator lamp will go
out by itself
4. After a few minutes driving time, the
Flat Tire Monitor adopts the current
pressure levels as the reference, and
from that point on, can detect and
report a flat tire.

Parking lamps/Low beamsParking lamps
The front, rear and side vehicle
lighting is switched on. You can
use the parking lamps for
parking. For lighting on one side for
parking as an additional feature, refer to
page 78.
Low beams
When the ignition is switched off
while the low beams are on, the
headlamps go out and only the
parking lamps remain on.
FOLLOW ME HOME lamps:
When you activate the headlamp
flasher after parking the vehicle with the
lights turned off, the low-beam head-
lamps will come on for a short time. You
can also have this function deacti-
vated.<
LIGHTS ON warningWhen you open the driver's door, after
having turned the ignition key to posi-
tion 0, you will hear an acoustic signal
for a few seconds to remind you that
the lamps have not been switched off.Daytime driving lamps
*
If you desire, the light switch can be left
in the second position:
When the ignition is switched off, the
external lighting is also switched off.
You can have the activation
settings for the daytime driving
lamps programmed on your vehicle.<
Automatic headlight control
*
When the switch is set to this
position the system automati-
cally activates and cancels the
low beams in response to changes in
ambient light ( in tunnels, at dusk, etc.)
as well as rain and snow.
The vehicle's external lights
remain on constantly when you
switch on the front fog lamps after the
headlights have come on automati-
cally.<
Automatic headlight control
cannot serve as a substitute for
the driver's judgement in determining
when the vehicle lights should be
switched on. For example, the sensors
are not able to detect fog. To avoid
safety risks, you should respond to
these kinds of low-visibility situations
by switching the headlights on manu-
ally.< You can have the sensitivity of
your vehicle's automatic head-
light control adjusted.<

Air conditioningAir supply
You can select blower speeds
from 1 to 4. The heating and
ventilation become more and
more effective as the air
supply settings are increased. In
position 0, the blower and the heater
are switched off. The outside air supply
is blocked in position 0.
Temperature
In order to increase the
temperature of the passenger
compartment, turn to the right
(red). The temperature of the
incoming air is kept constant.
Air distribution
You can direct air to flow onto
the windows , toward your
upper body or into the
footwell . All intermediate
settings are possible. In the setting,
there is a low flow of air onto the
windows to keep them free of conden-
sation.
Rear window defroster
When the rear window defroster
is activated, the indicator lamp
comes on. The rear window defroster
switches off automatically.
The rear window defroster auto-
matically assumes operation
within 5 minutes after the engine is
started at outside temperatures below
approx. 39 7 (+4 6).<
Air conditioning
The air is cooled and dehumidi-
fied and Ð depending on the
temperature setting Ð rewarmed.
Depending on the weather, the wind-
shield may fog over briefly when the
engine is started. Switching on the air
conditioning will reduce condensation
forming on the windows.
Condensation forms during opera-
tion of the air conditioning system,
which then exits under the vehicle.
Traces of condensed water of this kind
are thus normal.<
Recirculated-air mode
You can respond to unpleasant
external odors by temporarily
excluding the supply of outside air. The
system then recirculates the air
currently within the vehicle.
If the windows should fog over in
the recirculated-air mode, switch
this mode off and increase the air
supply as required.<
