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

Alternator 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.
You should never attempt to
continue driving with a defective
drive belt, as the engine could overheat
and sustain serious damage. A defec-
tive drive belt will also make the vehicle
harder to steer.

<

Engine oil pressure



l


May be accompanied by the
warning "STOP!ENGINE
OILPRESS" in the Check Control
display panel: stop vehicle and switch
off engine immediately. Check level of
oil in engine, top up as required. If oil
level is correct: please contact the
nearest BMW center.
Stop at once. Attempts to
continue driving can lead to
serious engine damage stemming from
a lack of adequate lubrication.

Brake system hydraulic
circuits

l
Have the brake fluid level
checked. Before driving further, be sure
to read the notes on pages 108
and 118
The indicator lamp comes on together
with the "CHECK BRAKE LININGS"
message in the Check Control.

Keys Central locking system1 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 steering
lock as you drive.
For this reason, if you have a master
key that is not in regular use, you
should use that key approx. once every
year while driving for an extended
period to charge the battery. For addi-
tional information refer to page 28.< 463de023
2 Spare key for storage in a safe place
such as in your wallet. This key is not
intended for continuous use
3 Door and ignition key
The lock for the glove compartment
cannot be operated with this key.
This is recommended for valet
parking, for instance
The conceptThe central locking system is ready for
operation when both front doors are
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 driver's door lock
as well as via the remote control

>from inside via the central locking
system button.
The fuel filler door is not locked when
you open the vehicle from the inside
(refer to page 31). The anti-theft system
is automatically armed whenever you
activate the central locking system from
outside of the vehicle. Both the door
locks and release handles remain
locked. The alarm system is also acti-
vated or deactivated. When you use the
central locking system to lock the doors
from inside the vehicle, it will automati-
cally disengage the locks if an accident
occurs, except on doors that have been
locked individually using the lock
buttons, refer to page 31. The accident
response routine also includes auto-
matic activation of the hazard warning
flashers and the interior lamps.

Opening and closing Ð via the remote control

The concept

The remote control gives you an excep-
tionally convenient method for
unlocking and locking your vehicle.
Furthermore, it provides two additional
functions that can only be executed by
means of the remote control:

>

To switch on interior lamps, refer to
page 29
With this function, you can also
"search for" your vehicle Ð when
parked in an underground garage, for
instance

>

To open the luggage compartment
lid, refer to page 29
The luggage compartment lid will
open slightly, regardless of whether it
was previously locked or unlocked

>

Panic mode, refer to page 29
In case of danger, you can trigger an
alarm.
When you unlock (lock) your vehicle the
system automatically deactivates (acti-
vates) the anti-theft system and disarms
(arms)


the alarm system while also
switching on (off) the interior lamps.
You can have a signal set as an
acknowledgment message that
the vehicle is closed correctly.

1 Unlock, convenience opening and
alarm system
2 Lock and secure, interior lamp activa-
tion, disarming tilt alarm sensor and
interior motion sensor
3 Open the luggage compartment lid,

Master keys 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. For more
information refer to page 26.
Prevent unauthorized use of the remote
control by surrendering e. g. only the
door and ignition key 3 or the spare
key 2 (refer to page 26) when leaving
the vehicle for valet parking.
In the event of a system malfunction,
please contact your BMW center, which
is also your source for replacement
keys.

Alarm systemThe 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)
>Variations in the vehicle's tilt angle of
the kind that occur during attempts to
steal the wheels or tow the vehicle
>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
>The hazard warning flashers are acti-
vated for approx. five minutes
>The high beams flash on and off in
the same rhythm as the hazard
warning flashers.
To 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 messages set to confirm
arming and disarming.<
You can also open the luggage
compartment lid when the system is
armed by pressing the button on the
remote control (refer to page 29). When
you close the luggage compartment lid,
the luggage compartment 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: a door (or doors), the hood,
luggage compartment lid or rear
window are not completely closed.
Even if you do not respond by
securing the indicated area, the
system will start monitoring all other
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 armed39mde084

Sliding/tilt sunroof
*
Despite this safety feature, be
extremely careful to ensure that
the closing path of the roof is not
obstructed. Remember that the safety
mechanism may not be able to detect
every kind of potential obstruction (very
thin objects, for instance). You can
disable this safety feature by pressing
the switch beyond the pressure point
and holding it.<
Sliding/tilt sunroof with moonroof
insert
*
The options and control procedures are
essentially the same as those previ-
ously described for the sliding/tilt
sunroof. In order to open the raised
roof, press the control switch towards
"Open" and maintain pressure until the
roof has reached the desired position.
The headliner insert slides back some-
what when you raise the sunroof, and
retracts along with the sunroof panel
when you slide it back. The insert then
remains open, and you can slide it back
and forth to adjust it whenever the
sunroof is not fully retracted.
Interruption in the electrical
supplyAfter interruptions in the electrical
supply (when the battery is discon-
nected, for instance), the sunroof may
only lift. To reinitialize the mechanism:
1. Raise the sliding/tilt sunroof fully
2. Press and hold the switch for approx.
20 seconds.39mde139
Manual operation In the event of an electrical malfunction,
you can also operate the sliding/tilt
sunroof manually.
1. Remove the interior lamp, then reach
into the exposed opening and press
out the cover
2. Use the Allen key from the onboard
tool kit (refer to page 124) to turn the
sliding/tilt sunroof in the desired
direction. 390de376

Starting the engine Switching off the engine Starting engineDo not press the accelerator pedal
while starting the engine.
While it is important not to release
the key prematurely, you should
also avoid allowing the starter to
operate continuously for more than
20 seconds at a time. Release the igni-
tion key immediately when the engine
starts.<
Do not warm up the engine by allowing
it to run with the vehicle parked.
Instead, you should drive away immedi-
ately while taking care to avoid high
engine speeds until the engine warms
to its normal operating temperature.
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 extremely low tempera-
tures of roughly +57 (Ð156) or below
and at altitudes of over 3,300 ft
(1,000 m):
>Allow the starter to turn somewhat
longer (approximately 10 seconds)
during your initial starting attempt.
The engine's idle speed is automatically
regulated by the computerized engine-
management system. A brief period at
high idle is normal just after starting; the
idle speed should gradually return to
normal as the engine warms. Should
the engine fail to revert to its normal
idle speed after warming, a problem
may exist: please refer the problem to
your BMW center.
To prevent the battery from discharging,
always switch off any electrical devices
not in use, as well as the ignition when
the vehicle is not being driven.
Extended starting attempts, char-
acterized by excessively frequent
or long periods with the starter
engaged, can lead to catalyst
damage.<
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 serious
personal injury and property damage.<
Turn the ignition key to position 1 or 0.
Do not remove the ignition key
while the vehicle is still moving. If
you do so, the steering will lock, making
it impossible to steer the vehicle.
When you leave the vehicle, always
remove the ignition key and engage the
steering lock.
Always engage the parking brake
when parking on hills and inclined
surfaces, as even first gear or reverse
may not provide adequate resistance to
rolling.<

Automatic climate control Air conditioning
The air is cooled and
dehumidified and Ð
depending on the temperature setting Ð
warmed again when the air conditioning
is switched on.
Depending on the weather, the wind-
shield may fog over briefly when the
engine is started. You can reduce
condensation forming on the windows
by switching on the air conditioning.
Condensation forms in the air
conditioning during operation,
which then exits under the vehicle.
Traces of condensed water of this kind
are thus normal.<
Maximum cooling
At outside temperatures
above roughly 41 7 (5 6)
this program furnishes maximum
cooling whenever the engine is running.
The temperature displays 9 jump to
60 7 (16 6), the system reverts to
operating in the recirculated-air mode
and maximum airflow emerges from the
ventilation outlets only. That is why you
need to keep these open if you select
this program.
Automatic recirculated-air control
You can respond to
unpleasant external odors
by temporarily excluding the flow of
outside air. The system then recircu-
lates the air currently within the vehicle.
By repeated actuations of the button,
you can select one of three different
operation modes.
>Indicator lamps off: outside airflow
operational
>Left-hand indicator lamp on Ð AUC
mode: the system recognizes pollut-
ants in the outside air and blocks the
flow of air when necessary. The
system then recirculates the air
currently within the vehicle.
Depending on the air quality, the
automatic system then switches back
and forth between outside air supply
and recirculation of the air within the
vehicle
>Right indicator lamp on Ð recircu-
lated-air mode: the flow of external air
into the vehicle is permanently
blocked. The system then recirculates
the air currently within the vehicle.
If the windows should fog over in
the recirculated-air mode, switch
it off and increase the air supply as
required.<
Rear window defroster
When the rear window
defroster is activated, the
indicator lamp comes on. The rear
window defroster switches off automat-
ically.
Residual heat mode
The heat which is stored in
the engine is utilized for
heating the interior when the engine
has been switched off (while waiting at
a railroad crossing, for instance). In
ignition key position 1, you can alter the
settings of the automatic climate
control. With the ignition key in posi-
tion 0, the system automatically directs
heated air to the windshield, side
windows and footwells.
This function is available for oper-
ation when the outside tempera-
ture is below approximately 59 7
(15 6), with the engine warm from
recent operation and an adequate
charge in the battery. The LED on the
button will light up when all conditions
have been met.<
