ComputerAdjustments From ignition key position 1:
To set ahead: turn the button to the
right.
To set back: turn the button to the left.
The adjustment speed will increase the
longer you continue to hold the button.
To change the display mode: press the
knob briefly. Every time you press the
knob, the clock display alternates
between the 12-hour or 24-hour mode.
In ignition key position 0: the time is
displayed for a few seconds after you
press the left button (refer to "Odom-
eter", page 69).
Outside temperature You can change the units of measure
(6/7) for the outside temperature
display by pressing the right-hand reset
button in the instrument cluster while
the temperature display is active.
Ice warning If the outside temperature drops to
about 37.5 7 (+3 6), then the
computer will automatically switch to
show the outside temperature. In addi-
tion, a signal sounds as a warning and
the display flashes for a brief period.
This warning will repeat itself whenever
the temperature has reached at least
43 7 (+6 6) since the last warning,
and has then dropped further to
37.5 7 (+3 6).
Ice warnings do not exclude the
possibility that surface ice can still
occur at temperatures above 37.5 7
(+3 6), e. g. on bridges and shady
roads.<

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 range for the two middle
sensors is slightly less than 4.9 ft
(1.50 meters).
The system is activated automatically
about one second after you engage
reverse with the ignition key in posi-
tion 2. PDC is deactivated 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 have your BMW center
resolve the problem.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.
Always maintain a distance of more
than 4 in (10 cm). <

Tire Pressure Warning (RDW)The conceptThe Tire Pressure Warning (RDW) moni-
tors the tire pressure in all four wheels
while driving. The system detects
whenever the inflation pressure in a tire
drops significantly.
Controlling the tire pressure is based
on monitoring the speed of the tires
relative to each other. A flat tire is
detected and reported because the
speed suddenly deviate drastically from
one another.
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 correcting the
inflation pressure and letting the system
"learn" what condition is required.
1 Check the tire inflation pressure in all
the tires, comparing them with the
inflation pressure table (page 27),
and adjusting their pressure if neces-
sary
2 Turn the ignition key to position 2
3 Continue to press the button until the
yellow indicator lamp in the instru-
ment cluster lights up. After a short
time, the indicator lamp will go out
automatically
4 After a few minutes, the RDW will
accept the current inflation pressure
as the value to be measured against,
and from that point on, can detect
and report a flat tire.

Tire Pressure Warning (RDW)Activating/deactivating the
systemThe system is automatically active in
ignition key position 2 and is therefore
always on during driving.
To deactivate the system: tap the
button, the indicator lamp will light up
yellow.
To activate the system: tap the button
again, the indicator lamp goes out.
Deactivate the system while driving
with snow chains, since false warnings
and undetected losses in pressure are
possible under these kinds of condi-
tions.
Flat tire
The indicator lamp in the instru-
ment cluster will light up red in
the event of tire pressure loss.
In addition, an acoustic signal is
sounded. To come to an immediate
stop, reduce speed, while avoiding any
sudden, jerky braking or steering
maneuvers.
Fix the flat tire using the M Mobility
system (refer to page 145).
Reset the indicator lamp: the red indi-
cator lamp must be switched off manu-
ally after mounting a new wheel. At this
point, hold the RDW switch down until
the indicator lamp goes out. Reinitialize
the system afterward.
The RDW cannot alert you to
severe and sudden tire damage
caused by external factors.
The RDW will not identify the natural
loss of pressure in all four tires, either.<
Check the tire inflation pressure
on a regular basis and correct if
necessary. Refer to page 26.
Under certain circumstances, there
may be false warnings or a delayed
detection of pressure losses when
driving on snow-covered or slippery
road surfaces.
A sporty driving style (slip at the wheels
receiving the torque, high lateral accel-
eration) can lead to delayed RDW warn-
ings.<
System malfunctionAs long as there is still a malfunction,
the indicator lamp in the instrument
cluster will stay lit up yellow.
Please contact your BMW center for
additional information.

Side lamps
With the switch in this position,
the front, rear and side vehicle
lighting comes on. You can use
the side marker lamps for parking.
Refer to page 82 for one-sided lighting
as an additional possibility for parking.
Low beam headlamps
When you switch the ignition off
with the low beam headlamps
on, only the side lamps will
remain on.
"Follow-Me-Home" lamps:
If you activate the headlamp
flasher after you have parked the
vehicle, the low beam lamps will remain
on for a short period of time. You may
also have this function deactivated if
you wish.<
"LIGHTS ON" warningWhenever you open the driver's door,
after having turned the ignition key to
position 0, you will hear a buzzing
sound for a few seconds to remind you
that the lamps have not been switched
off.Daytime running lamps
*
If you desire, the lamp switch can be
left in the second position. When the
ignition is switched off, the external
lighting is also switched off.
Turn the rotary dial to control the
lighting when the side or low beam
lamps are on.

Antilock Brake System (ABS)In the event of a malfunction
If the ABS warning lamp does
come on, refer to page 21. The
brake system will then function
the same as on vehicles without ABS.
However, have the brake system
checked by your BMW center as soon
as possible. To prevent undetected
defects and cumulative faults from
adversely affecting the brake system,
refer any problems to your BMW center
at the earliest opportunity.
ABS warning lamp for Canadian
models.
If the brake warning lamp
comes on together with the
indicator lamps for ABS and
DSC, refer to page 21, the entire
ABS, CBC and DSC control
system has failed. Continue
driving cautiously and defen-
sively. Avoid full brake applica-
tions. This could cause the vehicle to
lose stability and you might no longer
be able to control it.
Have the system checked by your BMW
center as soon as possible.

Brake system Brake fluid level
If the brake warning lamp
comes on with the parking
brake released:
The brake fluid level is too low in the
reservoir (refer to page 126).
If the brake fluid level is too low and
brake pedal travel has become notice-
ably longer, there may be a defect in
one of the brake system's hydraulic
circuits.
Brake warning lamp for Cana-
dian models.
Proceed to the nearest BMW
center. Higher brake application
pressure may be necessary under these
conditions, and brake pedal travel may
be significantly longer. Please
remember to adapt your driving style
accordingly.<
Brake pads
If the warning lamp for the brake
pads lights up: only the
minimum pad thickness still
remains on the brake pads. Proceed to
the nearest BMW center as soon as
possible to have the pads replaced.
For your own safety: use only
brake pads which BMW has
approved for your specific vehicle
model. BMW cannot evaluate non-
approved brake pads to determine if
they are suited for use, and therefore
cannot ensure the operating safety of
the vehicle if they are installed.<
