Indicator and warning lamps

Technology that monitors itself

Indicator and warning lamps that are
identified by "

l

" are tested for proper
functioning whenever the ignition key is
turned. 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.
You will see how to react to this below.

Red: stop immediately

Battery charge current



l

The battery is no longer being
charged. Indicates a defective
alternator drive belt or a problem with
the alternator's charge circuit. Please
contact the nearest BMW center.
If the drive belt is defective, do not
continue driving, as the engine
could sustain serious damage from
overheating. If the drive belt is defec-
tive, increased steering effort is also
required.

<


Engine oil pressure


l

Stop the 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
damage from inadequate lubrication.

Flat Tire Monitor
l
In addition, an acoustic signal
sounds: a tire failure has
occurred. Reduce vehicle speed imme-
diately to stop the vehicle. Avoid hard
brake applications. As you steer the
vehicle, use caution and avoid overcor-
recting.
For additional information, refer to
page 77
Brake warning lamp

Keys Central locking systemThe key set1 The master keys with remote control
determine the functions of the Key
Memory, refer to page 55.
You can mark individual keys for
subsequent identification by applying
the colored decals that you received
when accepting delivery of your
vehicle
There is an extended-life battery
in every master key that is
charged automatically in the ignition
lock as you drive. For this reason, if you
have a master key that is otherwise not
used, use that key at least once every
year while driving for an extended
period to charge the battery, also refer
to page 30.<
2 Spare master key for storage in a
safe place, such as in your wallet.
This key is not intended for constant
use
3 Door and ignition key
The locks for the luggage compart-
ment lid and the glove compartment
cannot be operated with this key Ð
this is recommended for valet
parking, for instance
The conceptThe central locking system is ready for
operation whenever the driver's door is
closed. The system engages and
releases the locks on the
>doors
>luggage compartment lid
>fuel filler door.
The central locking system can be
operated
>from outside via the door lock and
using the remote control
>from inside by pressing a button.
If it is operated from inside, the fuel
filler door will not be locked, refer to
page 33.
When the system is actuated from
outside the vehicle, the anti-theft
system is simultaneously activated.
Both the door locks and release
handles remain locked. The alarm
system is also armed or disarmed.
Information for your safety: if locked
from inside, the central locking system
unlocks automatically in the event of an
accident. In addition, the hazard
warning flashers and interior lamps
come on.

Opening and closing Ð via the remote control The conceptThe remote control gives you an excep-
tionally convenient method for
unlocking and locking your vehicle.
Furthermore, it provides two additional
functions which you can only execute
via the remote control:
>Switch on the interior lamps, refer to
page 31.
With this function, you can also
"search for" your vehicle Ð when
parked in an underground garage, for
instance
>Open the luggage compartment lid,
refer to page 31.
The luggage compartment lid will
open slightly, regardless of whether it
was locked or unlocked.
The anti-theft system is also deacti-
vated/activated simultaneously with the
unlocking or locking of the vehicle, the
alarm system is disarmed/armed, and
the interior lamps are switched on/off.
You can have a signal set to
confirm that the vehicle's locks
have engaged securely.<
1 Unlock, convenience mode opening
and alarm system
2 Lock and secure, switch on interior
lamps, deactivating tilt alarm sensor
and interior motion sensor
3 Open the luggage compartment lid,
panic mode (trigger alarm)
Master key with remote control
Since passengers or animals
remaining in the vehicle might be
able to lock the doors from the inside,
take the vehicle's keys with you so that
the vehicle can be opened again from
the outside at any time.<
Master keys that are used repeat-
edly are always ready for opera-
tion, since the battery in the key is
charged automatically in the ignition
lock as you drive.
If it is no longer possible to unlock 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, refer also
to page 28.
Guard the remote control against unau-
thorized use by only surrendering the
spare key or the door key (refer to
page 28) e.g. for valet parking.
In the event of a system malfunction,
please contact your BMW center. You
can also obtain replacement keys
there.<

Alarm system
*
The conceptThe vehicle alarm system responds:
>When a door, the hood or the
luggage compartment lid are opened
>To movement inside the vehicle (inte-
rior motion sensor)
>To variations in the vehicle tilt, as
would occur while attempting to steal
the wheels or tow the vehicle (tilt
alarm sensor)
>To interruption of battery voltage.
The system responds to unauthorized
vehicle entry and attempted theft by
simultaneously activating the following:
>Sounding an acoustic alarm for
30 seconds
>Activating the hazard warning
flashers for approx. five minutes
>Flashing the high beams on and off in
rhythm with the hazard warning
flashers.
To arm and disarm the alarm
systemWhen the vehicle is locked or unlocked
by using a key or 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
compartment lid when the system is
armed by pressing the button of the
remote control, refer to page 31. When
it is closed, the lid is once again
secured.
Indicator lamp displaysThe indicator lamp is located under the
interior rearview mirror.
>When the indicator lamp flashes
continuously: the system is armed
>The indicator lamp flashes when it is
armed: the door(s), the hood or
luggage compartment lid are not
completely closed. Even if you do not
close the alerted area, the remaining
areas are secured, 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 armed

Starting the engine Switching off the engine If the engine does not start on the first
attempt (the engine is very hot or cold,
for instance):
>Press the accelerator pedal halfway
down while engaging the starter.
Cold starts at very low temperatures,
starting at about +57 (Ð156) and at
high altitudes over 3,300 ft (over
1,000 m):
>On the first start attempt, engage the
starter for a longer period (approx.
10 seconds)
Extended starting attempts, char-
acterized by excessively frequent
or long periods with the starter
engaged, can lead to damage to the
catalytic converter.<
When driving, standing at idle,
and parking the vehicle, take care
to avoid contact between the exhaust
system and flammable materials (grass,
hay, leaves, etc.). Such contact could
lead to a fire, resulting in personal injury
and property damage.<
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
discharging, always switch off electrical
devices that are not in use. Switch the
ignition off when the vehicle is not
being driven.Turn the ignition key to position 1 or 0.
Do not remove the ignition key
while the vehicle is still moving.
If you did so, the steering lock would
engage when the steering wheel is
turned.
When you leave the vehicle, always
remove the ignition key and engage the
steering lock.
Set the parking brake when parking on
steep hills, because under certain
conditions, putting the vehicle into first
or reverse gear may not be enough to
prevent it from rolling away.<
Vehicles with sequential M transmis-
sion
