FORGOTTEN KEY PREVENTION
FUNCTION

• If the driver's door is locked while it is open and

when the key is still in the ignition key cylinder,
approximately 0.3 second later the ETACS-ECU
activates the unlock relay output for 0.25 second
to prevent the door from being locked with the
key inside the vehicle. In addition, if locking the
door was not prevented, a re-try current is sent
(an unlock relay output ON is sent for 0.25 sec-
ond up to 5 times including the first attempt).

• If the passenger's door or driver's door are locked

while the passenger's door is open and when the
key is still in the ignition key cylinder, approxi-
mately 0.3 second later the ETACS-ECU acti-
vates the unlock relay output for 0.25 second to
prevent the door from being locked with the key
inside the vehicle. In addition, if locking the door
was not prevented, a re-try current is sent (an
unlock relay output ON is sent for 0.25 second up
to 5 times including the first attempt).

POWER WINDOW RELAY CONTROL

POWER WINDOW RELAY OPERATION

If the ignition switch is turned to "ON" position, the
power window relay is energized to activate the
power windows.

POWER WINDOW TIMER FUNCTION

Even after the ignition is switched off, the
ETACS-ECU keeps the power window relay acti-
vated for approximately 30 seconds, enabling raising
and lowering of the power windows by using the
power window switches. After approximately 30 sec-
onds, the power window relay is deactivated. During
this timed operation, if the driver or passenger doors
are opened, the power window relay is deactivated
from that moment.

KEYLESS ENTRY SYSTEM

KEYLESS ENTRY HAZARD ANSWER-
BACK FUNCTION

If the keyless entry transmitter is used to send a lock
signal to the ETACS-ECU, all doors, the liftgate, and
the glass hatch are locked and the hazard warning
lights flash once. If an unlock signal is sent, the
driver's door is unlocked first, and if a second signal
is sent, all doors, the liftgate, and the glass hatch are
unlocked. Each time the unlock signal is sent, the
hazard warning lights flash twice.

KEYLESS ENTRY HORN ANSWERBACK
FUNCTION

If the keyless entry transmitter is used to send 2 lock
signals to the ETACS-ECU, the first signal locks all
doors, the liftgate, and the glass hatch, while the sec-
ond signal sounds the horn once.

TRUNK UNLOCK FUNCTION

Press the "TRUNK" button twice within 5 seconds
and the trunk lid will be unlocked.

TIMED LOCKING MECHANISM

After unlocking the doors with the keyless entry
transmitter, if no doors are opened or if the ignition
key is not inserted, the ETACS-ECU automatically
locks the doors in 30 seconds.

SUNROOF CONTROL

SUNROOF TIMER FUNCTION

The ETACS-ECU enables opening and closing of the
sunroof for 30 seconds after the ignition is switched
off. During this timed operation, if the driver's or front
passenger ’s door is opened, the sunroof timer func-
tion is deactivated from that moment.

WINDSHIELD WIPERS AND WASHERS

LOW SPEED WIPER, HIGH SPEED WIPER
CONTROL

• When the ignition switch in at the ACC or ON

position, and the windshield low speed wiper
switch of the column switch is turned ON, the
front-ECU turns ON the windshield wiper drive
signal, turns OFF (LO) the windshield wiper
speed relay, and operates the windshield wiper at
low speed.

• When the windshield high speed wiper switch is

turned ON, the windshield wiper drive signal is
turned ON, the windshield wiper speed switching
relay is turned ON (HI), and the windshield wiper
is operated at high speed.

INTERMITTENT CONTROL

ETACS-ECU uses the dial position of the variable
intermittent wiper control switch and the vehicle
speed signal sent by the combination meter to calcu-
late the interval to be sent to the front-ECU. The
front-ECU determines the intermittent time from the
input SWS data signal, and turns ON the windshield
wiper drive signal. When the wiper is at the STOP
position, the windshield wiper auto-stop signal goes
OFF to turn OFF the windshield wiper drive signal.
After the intermittent time from when the windshield
wiper drive signal turned ON, the windshield wiper
drive signal is turned ON again and the above opera-
tion is repeated.

MIST WIPER CONTROL

When the ignition switch is in the ACC or ON posi-
tion, and the windshield mist wiper switch of the col-
umn switch is turned ON, the front-ECU turns ON the
windshield wiper drive signal. At the same time, the
wiper speed switching relay is turned ON
(HIGH-SPEED). While the windshield mist wiper
switch is ON, the windshield wiper will operate at
high speed. Then, if the windshield mist wiper switch
is turned off, the wiper operates at low speed until it
stops at the predetermined park position.
When the windshield mist switch is turned on briefly,
the wiper operates once at low speed.
At the point the windshield mist switch is turned ON,
if the windshield wiper has been operating intermit-
tently, the same operations as the above will be per-
formed while the windshield mist wiper switch is ON.
After the windshield mist wiper switch goes OFF, the
intermittent operations will be set again after the
windshield wiper auto-stop signal last is turned ON.

WASHER CONTROL

When the ignition switch is in the ACC or ON posi-
tion, and the windshield washer switch of the column
switch is turned ON, the front-ECU turns ON the
windshield washer relay. The windshield wiper drive
signal is turned ON in 0.15 seconds until 2 seconds
after the windshield washer switch goes OFF to
operate the windshield wiper continuously. When the
windshield washer switch is turned ON, if the wind-
shield wiper is operating intermittently, intermittent
operations will be continued after continuous opera-
tions.

HEADLIGHT

HEADLIGHT AUTOMATIC SHUTDOWN
FUNCTION

Even if the lighting switch (tail light switch or head-
light switch) is ON, the headlights and tail lights will
automatically go off in the following conditions to pre-
vent the battery from discharging:
When the ignition key is turned from "ON" to "LOCK"
(OFF) or "ACC" position with the lighting switch
turned ON, and this state continues for three min-
utes, the light will automatically be turned off. If the
driver's seat door is opened during these three min-
utes, the light will go off one second later.

HIGH-BEAM INDICATOR

At the same time that the high beams are illumi-
nated, the ETACS-ECU sends a signal to illuminate
the high-beam indicator via the CAN bus line. The
combination meter receives the transmitted signal
and turns the high-beam indicator on and off.

FLASHER TIMER

TURN-SIGNAL LIGHT

The turn-signal light output (flashing signal) is turned
ON when the ignition switch is ON and the turn-sig-
nal light switch is ON (LH or RH). If the front turn-sig-
nal light or rear turn-signal light bulb has burned out,
the flashing speed increases to indicate that the bulb
has burned out.

HAZARD WARNING LIGHT

Detects the signal where the hazard warning light
switch input changes from OFF to ON, and reverse
the flashing state according to this signal. The haz-
ard warning lights toggle on and off whenever the
hazard warning light switch is operated.

TURN-SIGNAL INDICATORS

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

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 fol-
lowing conditions is met. The fog lights will also be
switched off automatically by headlight automatic
shutdown 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 while the

tail lights are on or the tail lights 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

ETACS-ECU makes it possible to force operation of
all ON and OFF light switches in the overhead con-
sole (the dome light, reading light, cargo area light,
rear personal lights, front door lights, and front foot
lights). This function is assigned higher priority than
the controls for the interior light switch that are per-
formed when the doors are in certain positions.

• When the lights are forced on, the illumination

level is 100% as all interior lights are switched on
(the dome light, reading light, cargo area light,
rear personal lights, front door lights, and front
foot lights). Even when all lights are forced on,
the interior light automatic shutoff function is
active.

• When the lights are forced off, all interior lights

are immediately switched off (the dome light,
reading light, cargo area light, rear personal
lights, front door lights, and front foot lights).

When the interior light switch is at DOOR position,
the ETACS-ECU controls the interior lights as fol-
lows:

• 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 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 all doors are 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 inte-
rior lights will go off at that point.

• To check keyless entry operations more easily,

the interior lights will flash twice when doors are
locked. When doors are unlocked, the interior
lights up at a luminance of 100 percent, and goes
off 15 seconds later.

INTERIOR LIGHT AUTOMATIC
SHUTDOUN 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 follow-
ing conditions to prevent the battery from discharging
as a result of forgetting to turn off the lights or incom-
plete closing of the door.

• When the ignition switch is turned off and more

than 30 minutes pass by with the interior light illu-
minated, the interior lights will go off automati-
cally.

• 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 auto-
matically.

SEAT BELT INDICATOR

If any of the following conditions is met with the igni-
tion switch at "ON" or "ST", the ETACS-ECU illumi-
nates, 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 seconds) if any of the following condi-
tions is met when sixty 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 ten 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 acti-

vated, 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.

DOOR-AJAR INDICATOR LIGHT

The combination meter receives the signal sent from
the ETACS-ECU about whether each door (including
the tailgate and glass hatch) is open or closed and
turns the door ajar indicator light on and off. While
the door ajar indicator is illuminated, the door ajar
warning function is activated and the door ajar indi-
cator light flashes 4 times. If the door remains open
even after the 4 warning flashes, the door ajar indica-
tor light will be illuminated again.
