HEADLIGHT

.

HEADLIGHT AUTOMATIC-SHUTDOWN FUNCTION THE INITIAL CONDITION: WITH 
FUNCTION (SPECIFICATION C: WHEN THE IGNITION SWITCH IS IN OFF POSITION IS 
TURNED ON, THE HEADLIGHTS ARE NOT TURNED OFF AUTOMATICALLY.)>

Even when the lighting switch (taillight switch or 
headlight switch) is ON, the headlight (including the 
taillights) turns off automatically under any of the fol-
lowing conditions to prevent the battery discharge 
caused by unattended operation.

• If the ignition switch is turned OFF with the light-

ing switch ON, the light turns off automatically 
after 3 minutes. If the driver's door is opened dur-
ing the 3 minutes, the light turns off after one sec-
ond (One seconds before turning off, the light 
reminder tone alarm sounds. However, if the 
driver's door is opened with the ignition key 
inserted, the key reminder alarm tone alarm oper-
ates in the first priority). 

• If the lighting switch is turned to the taillight posi-

tion from OFF with the ignition switch OFF, the 
lights do not turn off automatically.

After this function is activated, when the lighting 
switch is turned OFF and then ON or the ignition 
switch is turned ON, the headlights illuminate again.
NOTE: This function can be cancelled through cus-
tomization (Refer to Customization Function 

P.54A-17

).

.

AUTO LIGHT FUNCTION <VEHICLES WITH 
LIGHTING CONTROL SENSOR> (INITIAL 
SETTING: LIGHTING CONTROL SENSOR 
SENSITIVITY: LEVEL 3)

• Auto light function automatically turns ON/OFF the head-

light and taillight according to the signal from the lighting 
control sensor (light sensor) attached to the windshield 
when the lighting switch is in the AUTO position.

• The light sensor and the rain sensor are incorporated into 

the lighting control sensor. The light sensor is used for the 
auto light function, and the rain sensor for the rain sensitive 
wiper function

• The lighting control sensor (light sensor) detects the front 

and surrounding brightness of the vehicle. With this detec-
tion, it is judged that the vehicle enters a tunnel or just 
drives under a bridge. When it is judged that the vehicle 
drives through a tunnel, the headlight and taillight are auto-
matically turned ON. When it is judged that the vehicle 
drives under a bridge, the headlight and taillight are not 
turned ON automatically. When the vehicle surroundings 
get dark in case such as evening, the headlight and taillight 
are automatically turned ON.

• The timing that the headlight and taillight are automatically 

turned ON when the vehicle surroundings get dark in case 
such as evening can be adjusted by the customize function. 
(Refer to Customization Function

FLASHER TIMER FUNCTION

.

TURN-SIGNAL LIGHT (INITIAL SETTING: TURN 
SIGNAL LIGHT CAN BE OPERATED WHEN THE 
IGNITION SWITCH IS IN THE ON POSITION)

When the turn-signal light switch is ON (LH or RH) with the igni-
tion switch ON, the turn-signal light output (flash signal) is 
turned ON.
If the light bulb of the front or rear turn-signal light has burned 
out, the flashing speed becomes faster to alert the driver that 
the light bulb has burned out.
NOTE: Using a customization function, this function becomes 
available even when the ignition switch is in the ACC position. 
For more information about the Customization Function, refer 
to 

P.54A-17

.

.

COMFORT FLASHER FUNCTION (THE INITIAL 
CONDITION: WITH FUNCTION)

With the ignition switch in the ON position, when the turn signal 
switch is turned ON momentarily (0.4 second or less), 
ETACS-ECU turns ON the turn signal light output, and flashes 
the turn signal light three times.
NOTE: Using the customization function, "with function/without 
function" of the comfort flasher function and the switch accep-
tance time can be set. For more information about the Custom-
ization Function, refer to

HAZARD WARNING LIGHT

ETACS-ECU detects the signal that changes the hazard warn-
ing light switch from OFF to ON, and reverses the flashing state 
by the signal (to the flashing state when the hazard warning 
light is not flashing, and to the turned OFF state when flashing).
NOTE: 

.

1. The push-return switch has been adopted for the hazard 

warning light switch.

2. Even if the light bulb has burned out, the flashing speed of 

the hazard warning light is not changed.

DAYTIME RUNNING LIGHT

Illumination condition

• When all the conditions of ignition switch at ON 

position (engine is running), parking brake 
released (parking brake switch: OFF), and light-
ing switch at OFF or TAIL position are satisfied, 
the low-beam brightness is dimmed with the halo-
gen type vehicles and the daytime running light is 
illuminated with the discharge type vehicles.

Turning off condition

• The light is turned off when the ignition switch is 

in the OFF position, lighting switch is in the posi-
tion other than OFF or TAIL.

FOG LIGHT

.

FRONT FOG LIGHT FUNCTION

When the front fog light switch is turned to ON with 
the taillights or the headlights lit (the taillight switch or 
the headlight switch is ON), the ETACS-ECU illumi-
nates the front fog lights.

If the taillight or the headlight is turned off with the 
lighting switch OFF while the front fog lights lit, the 
front fog lights turn off at the same time to prevent 
unattended operation.
