triggering of the airbag restraint system, have
the testing, repair, removal, and disposal of air-
bag generators executed only by a BMW center
or a workshop that works according to BMW
repair procedures with correspondingly trained
personnel and has the required explosives
licenses. Unprofessional attempts to service
the system could lead to failure in an emer-
gency or undesired airbag activation, either of
which could result in personal injury.<
Warning notices and information about the air-
bags can also be found on the sun visors.
Automatic deactivation of the
passenger airbags
An analysis of the impression in the passenger
seat cushion determines whether and how the
seat is occupied. The front and side airbags for
the passenger are activated or deactivated by
the system accordingly.
The indicator lamp in the center console
shows the current status of the passen-
ger airbags, deactivated or activated, refer to
Status of passenger airbags below.<
Before transporting a child on the pas-
senger seat, observe the safety and han-
dling instructions under Transporting children
safely, refer to page36.
Adolescents and adults sitting in certain posi-
tions could inadvertently deactivate the front
and side airbags on the passenger side; the
indicator lamp for the passenger airbags comes
on. In such cases, the passenger should change
his or her sitting position so that the passenger
airbags are activated and the indicator lamp
goes out. If the passenger airbags cannot be
restored to the desired status despite the pas-
senger changing his or her seat position, use
the key switch to activate or deactivate the pas-
senger airbags, refer to page36. Do not attach
seat covers, seat cushion padding, ball mats or
other items to the passenger seat unless they
are specifically recommended by BMW. Do not
place any items under the seat which could
press against the seat from below. Otherwise a
correct analysis of the seat cushion is not
ensured.<
Status of passenger airbags
The indicator lamp for the passenger airbags
shows the functional status of the passenger's
front and side airbags in accordance with
whether and how the passenger seat is occu-
pied. The indicator lamp shows whether the
passenger airbags are activated or deactivated.
>The indicator lamp comes on as intended
when a child in an appropriate child-
restraint system is detected on the seat.
The front and side airbags for the passen-
ger are not activated.
>The indicator lamp does not come on as
long as a person of sufficient size and in a
correct sitting position is detected on the
seat. The front and side airbags for the pas-
senger are activated.
>The indicator lamp does not come on if the
seat is empty. However, the front and side
airbags for the passenger are not activated.
Operational readiness of the airbag
system
With the ignition key in position 1 or higher, the
warning lamp comes on briefly to indicate that
the entire airbag system and the belt tensioners
are operational.

Airbag system malfunction
>Warning lamp does not come on with the

respond in the expected manner to an impact
within its normal response range.<

* and daytime
running lamps
*
When you park the car, all its outside lamps are
switched off automatically if the light switch is in
position0, 2 or 3.
If you want the parking lamps to be on, turn the
switch to position1.
Parking lamps
In switch position1, the front, rear and side
vehicle lighting is switched on. You can use the
parking lamps to signal the position of the vehi-
cle when it is parked. For the additional option
of roadside parking lamps on one side of the
vehicle only, refer to page60.
The parking lamps will discharge the bat-
tery. Therefore, do not leave them on for
unduly long periods of time, otherwise the bat-
tery might not have enough power to start the
engine.<
Low beams
The low beams light up when the light switch is
in position 2 and the ignition is on.
Defective bulb
The indicator lamp lights up:
At least one bulb of the vehicle's exte-
rior lighting has failed.
For replacing bulbs refer to page98.
Automatic headlamp control*
When the switch is in position3, the low beams
are switched on and off automatically depend-
ing on ambient light conditions, e.g. in a tunnel,
in twilight, or if there is precipitation.
When driving into tunnels with bright overhead
lights, there may be a delay before the head-
lamps come on.
The headlamps may also come on when the
sun is sitting low on a blue sky.
The low beams remain switched on inde-
pendent of the ambient lighting condi-
tions when you switch on the fog lamps
*.<
If desired, the light switch can remain in
position3. The exterior lamps are automatically
switched off after the vehicle is parked.
The automatic headlamp control cannot
serve as a substitute for your personal
judgment in determining when the lamps
should be switched on in response to ambient
lighting conditions. For example, the system
cannot detect fog or hazy weather. To avoid
safety risks, you should always switch on the
lamps manually under these conditions.<
You can have the sensitivity of your vehi-
cle's automatic headlamp control
adjusted.<
Daytime running lamps*
If desired, the light switch can remain in the
automatic headlamp control position. The exte-
rior lamps are automatically switched off after
the vehicle is parked.
In the Parking lamps position, the parking lamps
come on after the ignition is switched off.
