Indicator and warning lamps

Technology that monitors itself

Indicator and warning lamps that are
identified by

●

are tested for proper
functioning whenever the ignition key is
turned. They each light up once for dif-
ferent 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.
You will see how to react to this below.

Red: stop immediately

Battery charge current

●

The battery is no longer being
charged. There is a malfunction
of the alternator drive belt or in the
charging circuit of the alternator. Please
contact the nearest BMW center.
If the drive belt is defective, stop
and switch off the engine immedi-
ately to prevent overheating and seri-
ous engine damage. If the drive belt is
defective, increased steering effort is
also required.

<

Engine oil pressure

●

An alarm sounds at the same
time. Stop vehicle immediately
and switch off engine. Check the
engine oil level and top up as required.
If the oil level is correct: please contact
the nearest BMW center.
Do not continue driving, as the
engine could sustain serious dam-
age from inadequate lubrication.

<

Flat Tire Monitor

●

In addition, an acoustic signal is
sounded: there is a flat tire.
Reduce speed and carefully come to a
stop. Avoid sudden braking and steer-
ing maneuvers.

30Opening and closing
KeysThe key set1Master keys with remote control
unit – these keys determine the func-
tions of the Key Memory, refer to
page 60.
You can mark the individual keys for
subsequent identification by apply-
ing the colored decals that you
received when accepting delivery of
your vehicle
In every master key with the
remote control feature there is an
extended-life battery that is charged
automatically in the ignition lock as you
drive.
For this reason, if you have master keys
with the remote control feature that are
not being used otherwise, use those
keys at least once a year while driving
for an extended period to charge the
battery.<
2Spare key – for storage in a safe
place, such as in your wallet. This key
is not intended for constant use. The
luggage compartment lid and the
glove compartment cannot be locked
and unlocked with this key. This is
useful for valet parking, for example.
Central locking systemThe conceptThe central locking system engages
and releases the locks on the:
>doors
>luggage compartment lid
>fuel filler door.
The central locking system is ready for
operation whenever the driver's door is
closed.
The central locking system can be
operated
>from outside via the door lock and
using the remote control
>from inside via the central locking
system button.
If it is operated from inside, the fuel
filler door will not be locked, refer to
page 34.
When the system is actuated from the
outside, the anti-theft system is also
activated. This prevents the doors from
being unlocked via the lock buttons or
the release handle. The alarm system is
also activated or deactivated.
If locked from inside, the central locking
system unlocks the vehicle automati-
cally in the event of an accident. In
addition, the hazard warning flashers
and interior lamps come on.

31
Opening and closing – via the remote controlThe conceptThe remote control also provides two
additional functions beyond the central
locking feature:
>Switch on the interior lamps, refer to
page 32.
With this function you can also
search for your vehicle – when
parked in an underground garage, for
instance
>Open the luggage compartment lid,
refer to page 32.
The luggage compartment lid will
open slightly, regardless of whether it
was locked or unlocked.
Whenever you unlock or lock the vehi-
cle, you simultaneously deactivate/acti-
vate the anti-theft system, disarm/arm
the alarm system and switch the interior
lamps on/off.
You can have a signal set to con-
firm that the vehicle's locks have
engaged securely.<
Master keys with remote control
Since passengers or animals
remaining in the vehicle might be
able to lock the doors from the inside,
always take the vehicle's keys with you
so that the vehicle can be opened again
from the outside at any time.<
If it is no longer possible to lock
the vehicle via the remote control,
the battery is discharged. Use this key
while driving for an extended period in
order to recharge the battery. To pre-
vent unauthorized use of the remote
control, surrender only the spare key
when leaving the vehicle for valet park-
ing, for example.
In the event of a system malfunction,
please contact your BMW center. You
can also obtain replacement keys
there.<

Floor matYou can turn the floor mat over to trans-
port soiled objects, etc. The rubber-
coated side can be washed and is
designed to inhibit sliding.
The fittings at the corners of the lug-
gage compartment provide you with a
convenient means of attaching luggage
compartment nets* and flexible straps
for securing luggage.
Refer also to Cargo loading on
page 104.
Alarm system*The conceptThe vehicle alarm system responds:
>When a door, the hood or the lug-
gage compartment lid are opened
>To movement inside the vehicle –
interior motion sensor
>To changes in vehicle tilt, e.g. as
would occur while attempting to steal
the wheels or tow the vehicle – tilt
alarm sensor system
>To interruption of battery voltage.
The system responds to unauthorized
vehicle entry and attempted theft by
simultaneously activating the following:
>Sounding an acoustical alarm for
30 seconds
>Activating the hazard warning flash-
ers for approx. five minutes
>Flashing the high beams on and off in
rhythm with the hazard warning flash-
ers.To arm and disarm the alarm
systemWhen the vehicle is locked or unlocked
via the driver's door lock or with the
remote control, the alarm system is also
simultaneously armed or disarmed.You can have a signal set as
acknowledgment for both arming
and disarming the alarm.<
You can also open the luggage com-
partment lid when the system is armed
by pressing the button of the remote
control, refer to page 32. When it is
closed, the lid is once again secured.
Extended pressure on the button sets
off the alarm – Panic mode, refer to
page 32.

Before exiting the vehicle with the
engine running, move the selector
lever into position N and apply the
parking brake.
Never leave the vehicle unattended
with the engine running. An unat-
tended vehicle with a running engine
represents a safety hazard.<
Engine idle speed is controlled by the
engine computer system. Increased
speeds at start-up are normal and
should decrease as the engine warms
up. If engine speed does not decrease,
service is required.
To prevent the battery from discharg-
ing, always deactivate electrical
devices that are not in use. Switch the
ignition off when the vehicle is not
being driven.

light sources for many of the controls
and displays in your vehicle. These
light-emitting diodes are related to con-
ventional lasers, and legislation defines
them as light-emitting diodes, Class 1.

128Laws and regulations
California Proposition 65 warningCalifornia laws require us to state the
following warning:
Engine exhaust and a wide variety
of automobile components and
parts, including components found in
the interior furnishings in a vehicle, con-
tain or emit chemicals known to the
State of California to cause cancer and
birth defects and reproductive harm. In
addition, certain fluids contained in
vehicles and certain products of com-
ponent wear contain or emit chemicals
known to the State of California to
cause cancer and birth defects or other
reproductive harm.
Battery posts, terminals and related
accessories contain lead and lead com-
pounds. Wash your hands after
handling.
Used engine oil contains chemicals that
have caused cancer in laboratory ani-
mals. Always protect your skin by
washing thoroughly with soap and
water.<
OBD interface socketThe Onboard Diagnostic (OBD) inter-
face socket is located on the left of the
driver's side at the bottom of the instru-
ment panel and under a cover. The
cover has the letters OBD on it.
The purpose of the OBD system is to
assure proper emission-control system
operation for the vehicle's lifetime by
monitoring emission-related compo-
nents and systems for deterioration and
malfunction.
An illuminated indicator informs
you of the need for service, not
that you need to stop the vehi-
cle. However, the systems should be
checked by your BMW center at the
earliest possible opportunity.
