CIRCUIT OPERATION

CIRCUIT OPERATION

Courtesy lamps

Automatic courtesy lamp facility enabled

With the tailgate or any of the four doors opened the
illumination level of the following lamps will fade on
over a period of approximately 0.5 seconds:

front courtesy lamp

rear left courtesy lamp

rear right courtesy lamp

load space lamps

front left footwell lamp

front right footwell lamp

ignition ring illumination

rear right footwell lamp

rear left footwell lamp

If any door is left open, the lamps will fade out after a
time of approximately 10 minutes. During the 10
minute time out, if any other door is opened the timer
will be reset.

If all doors are closed prior to the end of this 10
minute period then all specified lamps will fade out
after a delay of 15 seconds.

If the ignition is switched on before the end of the 15
second time out period, the specified lamps will
begin to fade out after a delay of 1 second.

If the ignition is then switched off and no door
opened, the 15 second time out of the lamps will not
be resumed.

If an unlock signal is received from the remote key,
or if a key unlock is received from either of the front
doors while all the doors are closed, then the
courtesy lamps will fade to on in 0.5 seconds and
begin a 15 second time out period.

If any of the doors or the tailgate are opened during
this delay, then the time out period will be restarted.

If all the doors are closed and a lock signal is
received from the remote key or either of the front
door CDL switches while the courtesy lamps are in
their 15 second time out period, then the time delay
will be cancelled and the lamps immediately faded
out.

Automatic courtesy lamp facility disabled

Whenever the main courtesy lamp switch is operated
for greater than 2 seconds, the automatic courtesy
lamp feature will switch between the enabled and
disabled mode upon release of the switch. At the

same time an “Int lamps off”/“Int lamps auto”
message will be displayed on the instrument pack.
This extended switch operation will also extinguish
the courtesy lamps if the button has been depressed
for 2 seconds, causing the system to switch from the
automatic to disabled mode, but otherwise will have
no effect on their state.While the automatic courtesy
lamp facility is disabled, the courtesy lamps may only
be switched on and off by momentary activation of
the main courtesy lamp switch. The change of lamp
state will occur on release of the switch.

Panel Dimmer:

Operation of the panel dimmer switch, with the side
lamps on, will alter the level of panel illumination be-
tween approximately 6 and 94%. Depressing the
switch momentarily will cause the illumination to in-
crease or decrease to the next level. Holding the
switch closed will cause the illumination to ramp to-
wards fully on or fully off.

The illumination level selected will be stored in the
BeCM’s non–volatile memory whenever the driver’s
seat store sequence is completed successfully, pro-
vided the side lamp switch is on. If the side lamp
switch is not on and a successful memory store se-
quence is completed, then the previously stored illu-
mination level will remain unchanged.

CIRCUIT OPERATION

Puddle lamps

With any door open and the automatic courtesy lamp
feature enabled, the puddle lamp within the relevant
door will be illuminated, either until the door is closed
or a time period of approximately 10 minutes has
elapsed. If any puddle lamp is on, momentary
operation of the courtesy lamp master switch will
extinguish all puddle lamps on release of the switch.

Further operation of the switch or reopening a door
(if automatic courtesy lamps are enabled) will again
activate the puddle lamps for those doors that are
open. If the courtesy lamp switch is held on for
longer than 2 seconds, the automatic operation of
the puddle lamps from the door open switches will
switch between enabled and disabled.
