HEADLAMP WASHER
If the headlamp washer switch at the steering
column is placed in the ON position when the ignition
switch is in the ACC or ON position and theheadlamp switch is in the ON position, the headlamp
washer drive signal is turned ON for 0.5 second.
IGNITION KEY HOLE ILLUMINATION LAMP
When the ignition switch is turned to LOCK (OFF) or
ACC position with the driver’s door opened, the
ignition key hole illumination lamp is illuminated.
If the door is closed in that state, the lamp goes out
after 30 seconds. Vehicles with keyless entrysystem, it illuminates for 30 seconds after the
ignition key is removed. In either case the lamp goes
out when the ignition switch is turned to ON position.
HEADLAMP
Headlamp Automatic Shutdown Function
If the ignition switch is turned to LOCK (OFF) or
ACC position, when the headlamps are on, the
headlamps will be switched off in three minutes.
If the driver’s door is opened within that three-minute
period, the headlamps will be switched off
automatically. This prevents the battery from
discharged.
In addition, if the headlamps are turned on when
the ignition switch is at LOCK (OFF) or ACC position,
the headlamps will not be switched off.Headlamp Dimmer Switch Automatic Reset
Function
This function allows the dimmer switch to be reset
to the low-beam position whenever the headlamp
switch is turned ON.
Daytime Running Lamp (DRL) Function

If the ignition switch is turned to ON when the
headlamps and tail lamps are off, the headlamps
(low-beam) and tail lamps turn on.
FLASHER TIMER
Turn-signal Lamp
When the ignition switch is turned to ON position
and turn-signal lamp switch is placed in the ON
position for right or left turn signaling, the system
generates turn-signal lamp drive signals (flashing
signals).
The system also notifies of a blown turn-signal lamp
bulb by shortening the flashing intervals of the
corresponding indicator lamp.Hazard Warning Lamp
The system detects a change from ON to OFF
of the hazard lamp input signal and activates the
hazard lamps if they are not in operation or
deactivates the lamps if they are operating (reversal
of state between activation and deactivation).
FRONT FOG LAMP
If the front fog lamp switch is turned ON at the
condition that the headlamp or the tail lamp is turned
ON (including the illumination by the automatic
lighting function), the front fog lamp is turned ON.Whenever the tail lamps are turned on at the next
time, the front fog lamps will always be off regardless
of the switch positions. In addition, if the tail lamp
is switched off by the automatic lighting system,
the front fog lamp will also be switched off. However,
the front fog lamp will be illuminated when the tail
lamp is switched on.

SWS -General Information54B-6
REAR FOG LAMP
If the fog lamp switch is turned ON when the
headlamp or the front fog lamp is turned On, the
rear fog lamp is switched ON and OFF alternatively.If the headlamp and the front fog lamp are turned
OFF during lighting of the rear fog lamp, the rear
fog lamp is turned OFF at the same time.
ROOM LAMP
With the room lamp switch in the DOOR position,
the ETACS-ECU controls the room lamp operation
as follows:
DWhen a door is opened from outside or inside
[with the ignition switch turned to LOCK (OFF)
position]:
When a door is opened, the ETACS-ECU
causes the room lamp to be illuminated at the
100% intensity. When the door is closed, it
dims out the room lamp to 65% intensity and
approx. 30 seconds later, turns out the lamp
completely. During this period (timer controlled
period), the room lamp goes out if the ignition
switch is turned to ON position or the doors
are locked.
DWhen a door is opened or closed with the
ignition switch in the ON position:
The room lamp illuminates at 100% intensity
when a door is opened and turned out when
it is closed.
DWhen no door is opened and the ignition key
is removed:When the ignition key is removed with all the
doors closed, the room lamp is illuminated at
an intensity of 100% and turned out approx.
30 seconds later. During that time
(timer-controlled period), the room lamp goes
out if the ignition key is inserted and turned
to ON position or the door locking system is
activated.
DRoom lamp’s answerback operation in
response to door lock control by keyless entry
system:
To allow the driver to ascertain the result of
the door locking/unlocking control action by
the use of the keyless entry system, the
ETACS-ECU causes the room lamp to blink
twice when the doors are locked through the
system and to illuminate for approx. 15 seconds
when the doors are locked.
The room lamp’s answerback operation in
response to a keyless entry system control
action is accompanied by operation of the
hazard warning lamps.
