DESCRIPTION AND OPERATION
The parking lamps are operated by moving the
lighting switch to the side lamp position with the key
out of the ignition switch. The parking lamps are
activated by the BeCM and operate according to the
position of the direction indicator switch as follows:
A. If the indicator switch is in the central position, all
side and tail lamps will be on
B. If the indicator switch is in the left hand position,
only the front left side and tail lamps will be on
C. If the indicator switch is in the right hand
position, only the front right side and tail lamps
will be on.
When the parking lamps are on, the interior switch
and instrument illumination remains off to minimise
battery drain.
When the parking lamps are selected on and the key
is inserted in the ignition the BeCM changes the
parking lamp switch position functionality to side
lamps.
If the parking lamps are operative and the driver’s
door is opened, the BeCM generates a ’PARK
LIGHTS’, ’LEFT PARK LIGHT’ or ’RIGHT PARK
LIGHT’ message in the message centre to inform the
driver that the parking lamps are on.
On vehicles from 96MY, the message centre displays
the applicable message as detailed above, but also
informs the driver via a triple audible chime that the
parking lamps are on.
Side Lamps
The side lamps are operated by moving the lighting
switch to the side lamp position with the key in the
ignition switch. The parking lamps are activated by the
BeCM which illuminates filament bulbs located in the
headlamps, tail lamp assemblies and number plate
lamps.
On NAS vehicles, the front side lamps are integral
with the front direction indicator lamp assemblies.
A ’lights on’ warning lamp is located in the instrument
pack and is illuminated to inform the driver that side
lamps or headlamps are on.
When the side lamps are selected on, the BeCM also
activates the illumination for the instrument pack,
fascia switches, ICE, HEVAC, centre console
switches and gear selector. The level of the interior
illumination is controlled by the panel dimmer control
located on the direction indicator column stalk.
If the key is removed from the ignition the BeCM
changes the lamps functionality to that detailed in
’parking lamps’.
Dipped Beam Headlamps
The dipped headlamps are operated by moving the
lighting switch, past the parking/side lamp position, to
the second headlamp position. The headlamps
operate regardless of the ignition switch position.
When dipped headlamps are selected, the BeCM
supplies power to illuminate halogen bulbs in the
headlamps and bulbs in the tail lamp assemblies.
On NAS vehicles the side lamps in the front direction
indicators remain illuminated.
Interior switch and instrument illumination is activated
by the BeCM as detailed in side lamps above. The
’lights on’ warning lamp in the instrument pack is also
illuminated to inform the driver that the headlamps are
on.
If the headlamps are operative and the driver’s door is
opened and the key removed from the ignition, the
BeCM generates a ’LIGHTS ON’ message in the
message centre to inform the driver that the
headlamps are on.
On vehicles from 96MY, the message centre displays
the applicable message as detailed above, but also
informs the driver via a triple audible chime that the
headlamps lamps are on.
Daylight Running Lamps
Daylight running lamps are a legislative requirement in
some markets. With the engine running at an engine
speed above 500 rpm, the BeCM will activate the
daylight running lamps regardless of the position of
the lighting switch. The daylight running feature has
no effect on other vehicle lighting systems.
When daylight running lamps are on, but the lighting
switch is off, the BeCM does not activate the interior
fascia illumination.
