FOG LIGHT

GENERAL DESCRIPTION CONCERNING THE FOG LIGHTS
The following ECUs affect the functions and control of the fog lights.







Fog light







The fog lights will illuminate only when the fog light switch is operated while the low-beam headlights are on.

The fog lights will be switched off when any of the following conditions is met. The fog lights will also be switched off automatically by headlight automatic shutoff function.
- When the high-beam headlights are switched on, the fog lights will be switched off. If the low-beam headlights are switched on again, the fog lights will illuminate again.
- When the headlight switch is turned off or the taillights and headlights are off, the fog lights will be switched off. If the low-beam headlights are switched on again, the fog lights will not illuminate again.

Fog light indicator
At the same time that the fog lights are illuminated, the ETACS-ECU sends a signal to illuminate the fog light indicator via the CAN bus line. The combination meter receives the transmitted signal and turns the fog light indicator on and off.

INTERIOR LIGHT

GENERAL DESCRIPTION CONCERNING THE INTERIOR LIGHT
The following ECUs affect the functions and control of the interior lights.







Interior light control function







The ETACS-ECU controls the interior lights by turning them on and off in the following way:
- When a door is opened with the ignition switch off, the interior lights up to a luminance of 100 percent. When a door is closed, the interior lights dims at a luminance of 65 percent, and goes off 30 seconds later. However if the ignition switch is turned ON or if a door is locked while the interior lights is dimming, the dome light will go off at that point.
- When a door is opened with the ignition switch ON, the interior lights up at a luminance of 100 percent. When a door is closed, the interior lights go off.
- When the ignition key is removed with all doors closed, the interior lights up at a luminance of 100 percent, and goes off 30 seconds later. However if the ignition key is inserted again or if a door is locked while the interior lights is lighting, the interior lights will go off at that point.
- To check keyless entry operations more easily, the interior lights is flashed once when the doors are locked. When the doors are unlocked, the interior lights at a luminance of 100 percent, and go off 15 seconds later.

NOTE:
- The dimmer function can be customized on vehicles equipped with a multi center display (middle grade type).
- The dotted lines indicate that lighting mode when the ignition switch is turned ON, door is locked, or any door is opened during the timer illumination time.

Interior light automatic-shutoff function







Illuminated interior lights such as the front dome light, etc. (all lights using the dome light fuse as the power supply) will automatically go off in the following conditions to prevent the battery from discharging as a result of forgetting to turn off the lights or incomplete closing of the door.
- When the ignition switch is turned off and more than 30 minutes pass with the interior light illuminated, the interior lights will go off automatically.
- When the ignition switch is turned off and one of the door switches remains open for 30 minutes continuously, the interior lights will go off automatically.

NOTE: The interior light automatic shutoff function can be customized on vehicles equipped with a multi center display (middle grade type).

Ignition key hole illumination light function
The ignition key hole illumination light illuminates when the driver's door is opened with the ignition switch off, and for 30 seconds after the driver's door is closed. It also illuminates for 30 seconds after the ignition key is pulled out. In any case, it goes out when the ignition switch is turned on.

Door ajar indicator
The combination meter receives the signal sent from the ETACS-ECU about whether each door is open or closed and turns the door ajar indicator on and off. While the door ajar indicator is illuminated, the door ajar warning function is activated and the door ajar indicator flashes 4 times. If the door remains open even after the 4 warning flashes, the door ajar indicator will be illuminated again. And when the interior light automatic-shutoff function is activated, the door ajar indicator is extinguished.

Seat belt indicator







If any of the following conditions is met with the ignition switch at "ON" or "ST", the ETACS-ECU illuminates, flashes or extinguishes the seat belt indicator by using the driver's seat belt switch signal and the vehicle speed signal sent from the combination meter.
- Illuminates when the ignition switch is at "ON" and the seat belt switch is turned on (the driver's seat belt is unfastened).
- Flashes and illuminates the indicator 12 cycles (after 0.5 second) if any of the following conditions is met when 60 seconds or more have elapsed since the ignition switch is turned "ON". One cycle consists of five-second "flashing" and then three-second "illumination".

a. The vehicle speed has reached 8 km/h (5 mph) while the seat belt switch is turned on (driver's seat belt is not fastened) with the ignition switch "ON."
b. The seat belt switch has been turned on (driver's seat belt has not been fastened) for at least 10 seconds while the ignition switch has been turned "ON" and the vehicle speed has been 8 km/h (5 mph) or more.

NOTE: Once this timer operation has been activated, it will not be activated again until the vehicle speed reduces to 3 km/h (2 mph) or less even if any of the following conditions is met.

- The indicator stops illuminating if the ignition switch or the seat belt switch is turned off (the driver's seat belt is fastened) while the timer operation is active.

THEFT-ALARM SYSTEM

GENERAL DESCRIPTION CONCERNING THE THEFT-ALARM SYSTEM
The following ECUs affect the functions and control of the theft-alarm function.







THEFT-ALARM SYSTEM

ARMED STAGE
Park the vehicle and stop the engine. Arm the system as described below:
- Remove the key from the ignition switch.
- Make sure that the engine hood is closed.
- Lock all doors and the trunk lid using power door lock switch or the remote control transmitter. After completion of the steps above, the theft-alarm indicator will illuminate for approximately 20 seconds and then continuously blink on and off, indicating that the system is armed.

NOTE:
- The system will be armed even if the engine hood is open, but when the system is set, be sure that the engine hood is closed.
- The system will be disarmed if, while the theft-alarm indicator (located in the front center of the dashboard) is illuminated, all doors or the trunk lid are unlocked by transmitter.
- The system will be disarmed if, while the theft-alarm indicator is illuminated, the ignition key is turned to the "ON" or "ACC."
- The system will not be armed if a door is not completely closed. Ensure that all the doors and trunk lid are closed, and arm the system again as described above.
