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.

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.
