Indicator and warning lamps

Technology that monitors itself

The system runs a check on the
warning and indicator lamps marked by
"

l

" each time you switch on the igni-
tion. They each light up once for
different periods of time.
If a fault should occur in one of these
systems, the corresponding lamp does
not go out after the engine is started or
it lights up while the vehicle is moving.
The following section describes how
you should respond.

Red: stop immediately

Battery charge current

l

The battery is no longer being
charged. This indicates a defect
in the alternator drive belt or in the
charging circuit of the alternator. Please
contact the nearest BMW center.
Stop and switch off the engine
immediately to prevent over-
heating and serious engine damage. If
the drive belt is defective, increased
steering effort is also required.

Alarm systemTo arm and disarm the alarm
systemWhen the vehicle is locked or unlocked
with the key or the remote control, the
alarm system is also simultaneously
armed or disarmed.
You can have different acknowl-
edgment signals set to confirm
arming and disarming.<
You can also open the luggage
compartment lid/tailgate when the
system is armed by pressing the button
on the remote control (refer to page 35).
When you close the luggage compart-
ment lid/tailgate, the luggage compart-
ment is secured again.
Indicator lamp displays>The indicator lamp below the interior
rearview mirror flashes continuously:
the system is armed
>The indicator lamp flashes during
arming: door(s), the hood or luggage
compartment lid/tailgate are not
completely closed. Even if you do not
secure the indicated 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 armed390de020
>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 unintentional alarmsThe tilt alarm sensor and interior motion
sensor may be switched off at the same
time. 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 alarm system)
twice in succession: press button 2 on
the remote control transmitter twice
(refer to page 35), or turn the key in the
door lock to the right (lock) twice in
succession (refer to page 33).
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.

Adjusting steering wheel Heated steering wheel
*
The steering wheel can be moved in
any of four directions. Adjust by moving
the control lever in the desired direc-
tion.
Do not adjust the steering wheel
while the vehicle is moving. There
is a risk of accident from unexpected
movement.<
To store the steering wheel setting,
refer to "Seat, mirror and steering
wheel memory" on page 54.390de711
Automatic steering wheel
adjustmentIn order to make it easier to get into and
out of the vehicle, the steering wheel
automatically moves into the top posi-
tion and returns to the driving (memory)
position.
This automatic feature is controlled by
the position of the ignition key and by
the driver's door.
The heated steering wheel feature is
available for operation when the ignition
key is in position 2.
Press the button to switch on and off.
The lamp within the button lights up
when the steering wheel heater is in
operation.
If you have a multifunction steering
wheel without steering wheel heating,
the button for the recirculated-air mode
is in this location (refer to page 22).

Switching off the engine Parking brakeTurn the ignition key to position 1 or 0.
Do not remove the ignition key
while the vehicle is rolling. The
steering locks, making it impossible to
steer the vehicle.
Always remove the ignition key and
engage the steering lock before leaving
the vehicle.
Vehicles with manual transmission:
Always engage the parking brake
when parking on hills and inclined
surfaces, as first gear or reverse may
not provide adequate resistance to
rolling.
Vehicles with automatic transmission:
Place the selector lever in "Park."<
Vehicles with automatic transmission:
The vehicle must be stationary and the
selector lever in "Park" before you can
remove the ignition key.
The parking brake is primarily designed
to prevent the vehicle from rolling while
parked. It operates on the rear wheels.To engageThe lever engages automatically and
the "PARK BRAKE" or "BRAKE" (in
Canada "P") indicator lamp comes on in
the instrument cluster in ignition key
position 2. Refer to pages 19 and 20.To releasePull up slightly on the lever, press the
button and lower the lever.390de714
If, in exceptional circumstances, it
should be necessary to engage
the parking brake while the vehicle is in
motion, do not pull it with excessive
pressure. Keep your thumb pressed
against the release button while care-
fully pulling up the lever to apply
moderate pressure.
Excessive pressure can lead to over-
braking and loss of traction (fishtailing)
at the rear.
The brake lamps do not come on when
the parking brake is applied.
Vehicles with manual transmission:
Always engage the parking brake
when parking on hills and inclined
surfaces, as first gear or reverse may
not provide adequate resistance to
rolling.
Vehicles with automatic transmission:
Place the selector lever in "Park."<
You can help prevent corrosion and
avoid uneven braking response by
gently engaging the parking brake from
time to time when coasting to a stop at
traffic lights (ensure that you will not
pose a hazard to other road users).

Washer/Wiper system
Turn the rain sensor off in auto-
matic car washes. Failure to do so
could result in damage caused by
undesired wiper activation.<
Normal wiper speedThe system automatically reverts to
operation in the intermittent mode
whenever the vehicle is stationary (not
on vehicles with rain sensor
*).
Fast wiper speedThe wipers revert to operation at stan-
dard speed when the vehicle stops (not
on vehicles with rain sensor
*).
Clean the windshieldThe system sprays washer fluid against
the windshield and activates the wipers
for a brief period.
Intensive cleaning
*
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 150.Cleaning headlights
*
When the headlights are on, they are
also cleaned automatically every fifth
time you activate the clean the wind-
shield (5) or intensive cleaning (6)
mode.
Do not use the washers if there is
any danger that the fluid will
freeze on the windshield, as your vision
could be obscured. Always use an anti-
freeze agent. Refer to page 139.
Do not use the washers when the reser-
voir is empty. 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.
