POWER WINDOWS
Power Windows Operation
A signal line dedicated for transmission of multiplex
communication data is connected between the
power window main switches and the power window
motor-ECU.
Communication is uni-directional. The power
window main switches have a transmitting circuit
only, whereas the power window sub switches have
a receiving circuit only.
Power Window Timer Function
With the ignition switch in the ON position, the power
window relay and power window switch receipt
permission signal (a SWS signal transmitted from
the ETACS-ECU) are turned ON [the power windowswitch receipt permission signal remains ON for 30
seconds after the ignition switch is turned LOCK
(OFF)], enabling opening and closing of the
windows. The power window relay goes ON for
additional 30 seconds. If the driver’s door is
subsequently closed during this period, the receipt
permission signal goes OFF. The power window
relay goes OFF 10 seconds after the receipt
permission signal goes OFF.
If the driver’s door is opened during timer operation,
the receipt permission signal goes ON for additional
30 seconds. If the driver’s door is subsequently
closed during this period, the receipt permission
signal goes OFF ten seconds after the receipt
permission signal goes OFF.
KEYLESS ENTRY SYSTEM
Keyless Entry System Operation
If the transmitter LOCK or UNLOCK switch is
pressed while the ignition key is removed and all
of the doors are closed, the doors can be locked
or unlocked.
Keyless Entry Answerback Function
The keyless entry hazard answerable function
facilitates confirmation of door locking and unlock-
ing operations even in daylight. When a LOCKsignal from the keyless entry transmitter is applied
to the ETACS-ECU, all of the turn-signal lamps flash
twice. When an UNLOCK signal from the keyless
entry transmitter is applied to the ETACS-ECU, all of
the turn-signal lamps flash four times. Note that an
unlock switch has change from OFF to ON.
NOTE
The hazard answer back is enabled or disabled
by the configuration function.
SUNROOF
Sunroof Operation
All of the slide open/close, tilt up/down, and stop
operations can be performed by a single switch.
When the roof lid glass is tilted up, the sunshade
opens approximately 98 mm in combined operation
with the roof lid glass for better ventilation.
A jam preventing mechanism has been adopted.
When a slide-close or tilt-down operation is blocked
by an external force, the roof lid glass moves back
and stops.Sunroof Timer Function
When the ignition switch is turned from ON position
to LOCK (OFF) or ACC position, the sunroof will
be ready to work for 30 seconds.
If the driver’s door is opened during the timer
operation, the timer operates for another
30
seconds starting from that point. However, the
timer operation discontinues if the door is closed
during that period.

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.
