Door coupled room lamp operation and dimming control ▶
When opening any of doors while the room lamp switch in overhead console is pressed in ("Door"
coupled position), the front and center room lamps come on. If the key is removed and door stays open,
the room lamps automatically goes off after 10 minutes. The sleep mode will be deactivated when the
door is locked or closed with the lamp OFF automatically.
When closing the door with IGN ON, the room lamps go off immediately.
When closing the door with IGN OFF, the room lamps stay on for 2 seconds more and are dimmed
out the side fascia panel.
When turning the ignition switch to ON position during dimming out operation, the room lamps go off
immediately.
When receiving the door unlock signal with IGN OFF, key removed and door closed, the overhead
console room lamp/center room lamp come on for 30 seconds.
For specification with the SKM, the lamps come on by the REKES unlock or passive unlock signal.
When receiving the door unlock signal again while the lamps stay on by the REKES or passive unloc
k
signal, the overhead console/center room lamps stays on for 30 seconds more. (the lamps stay on
when receiving door unlock signal)
When opening a door during the coupled operation and dimming operation, the room lamps stays
ON. When closing it again, the lamps stay on for 2 seconds more and are dimmed out for 3 seconds.
While the room lamps dim out when the driver/passenger/rear doors are open and closed, they go off
immediately when entering into the theft deterrent mode.
The room lamps come on when AUTO approach signal is received. 1.

Luminous intensity is a measure for the amount of light which passes through the unit area per
time unit. The SI unit of luminous intensity is the candela (cd), an SI base unit. -Luminous Intensity ▶
Luminance describes the amount of light that passes through or is emitted from a particular area,
and falls within a given solid angle. It is measured in sb or nt. -Luminance ▶
This indicates the amount of light reaching a given area. Measuring unit is lux (lx) and it is not
directly proportional to the brightness of the area as the reflection rate is not included. -Intensity of illumination ▶The LED stands for "Light Emitting Diode" or "Luminescent Diode." LED is a semiconductor diode
that emits incoherent narrow-spectrum light when electrically biased in the forward direction of the
p-n junction, as in the common LED circuit. In short, it is an element that converts electric signals
into light signals. Yellow, blue, red and white LEDs are currently available.
The followings are the advantages of LED.
It is not glaring and doesn't have short circuit unlike the conventional lamps.
It is semi-permanent and doesn't generate heat.
Its power consumption is much lower than those of conventional bulbs. -

(1) Headlamp
2) Operation
High-beam/low-beam
Most of the functions of the headlamp is controlled by the multifunction switch. The functions performed by
REKES or SMART key are controlled by the BCM.
The BCM controls the headlamp and tail lamp by using the data sent through the LIN communication from
the automatic light sensor when the multifunction switch is in AUTO position.
Control by BCM ▶
Coming home lighting control 1.
The headlamp is illuminated for 30 sec. when the ignition switch is turned on and then off with the
multifunction switch in ON or AUTO.
The headlamp is turned off right after the ignition is turned on. And when all the doors (including
tailgate) are closed the headlamp is illuminated for 30 sec.; and all the doors are open, the headlamp
is illuminated for 3 minutes.
This function can be deactivated or activated with a diagnostic equipment. -
-
-
DRL (Day Time Running Light) ▶
DRL is the function to turn on the high beam and tail lamp without any intervention from the light
switch. DRL turns off the lamps when turning off the light switch. This is an additional safety device to
prevent the accident.

(3) Tail lamp
The tail lamp is operated by the BCM when the BCM receives a signal from the multifunction switch.
Tail lamp warning ▶
The buzzer sounds for 10 seconds with the interval of 0.02 s ON and 1.38 s OFF when opening the
driver door with the key removed (without SKM)/with IGN OFF or ACC (with SKM) and tail lamp ON.
The buzzer stops its operation when turning off the tail lamp or closing the driver door during buzzer
operation. The buzzer stays ON when turning the tail lamp on again after turning it off during buzzer
operation. 1.
2.
Tail lamp auto turn-off ▶
When opening and closing the driver door after turning off the ignition with the tail lamp ON, the tail
lamps go off automatically.
The tail lamps come on again when inserting the ignition key (without SKM) and turning on the ignition
(with SKM) after tail lamp auto OFF.
The tail lamp should not go off when turning on the tail lamp switch with the ignition key removed
(without SKM) and with power off or ACC ON (with SKM). -

(5) Auto light (LIN)
The auto light sensor unit is installed to the back side of the ECM mirror located upper center of the
windshield, and detects the illuminance change. The BCM communicates with the auto light sensor
when the ignition is turned on, and turns on or off the tail lamp and headlamp automatically according to
the signals from the sensor when the multifunction switch is set to AUTO light.
The BCM communicates with the rain sensor even if the multifunction switch is in tail lamp.
Auto light switch Automatic light sensor unit
(6) Side repeater lamp
Side repeater lamp
The side repeater lamp is operated by the BCM when the BCM receives a signal from the multifunction
switch.
The BCM cycles the side repeater lamp and buzzer (ON/OFF) 75 times per minute.
The side repeater lamp operates only when IGN1 is ON.
If the side repeater lamp fails while it is illuminated, the BCM cycles the lamp and buzzer 100 times per
minute.
The lamp automatically flashes 3 times when the multifunction switch is turned on. If the switch is turned
off
during this operation, the lamp flashes 3 times and then goes off.
If the switch is turned off and then on during the 3 times of automatic flashing, the lamp flashes 3 more
times.

Operating the front room lamp and center room lamp switches illuminates the driver/passenger side
lamps and center room lamp.
Room lamp control by door coupled room lamp operation ▶
If a door except the tailgate is opened after the ignition is turned off, provided that door coupled front
room lamp switch is pressed, the front room lamp and center room lamp are illuminated for 2 sec.
and then fade out for 3 sec.
If a door except the tailgate is opened and then closed while the room lamp is fading out, the room
lamp is illuminated for 2 sec. and then fades out for 3 sec. If the ignition is turned on, the room lamp
goes off immediately.
The front room lamp and center room lamp are illuminated for 30 sec. when the door is unlocked by
the REKES or passive door UNLOCK function with IGN OFF and the ignition key removed. If the
REKES or passive door UNLOCK signal is received again, the room lamps are illuminated for
another 30 sec.
The room lamp goes off immediately when the REKES or passive door LOCK signal is received or
the ignition switch is turned to ON position.
If the room lamp is turned on after the ignition key is removed (door open or room lamp switch is
pressed), it is turned off after 10 minutes by the BCM.
When the door open state is changed or the ignition is turned on after the room lamp has been turned
off automatically, the battery saver feature is reset. 1.

2. RAIN SENSING SYSTEM
In the rain sensing wiper operation system, the rain sensing unit only sends the information about the
amount of rain drops to the BCM, and it does not operate the wiper directly. The wiper and washer are
controlled by the BCM according to the driver's choice.
Rain sensing unitMultifunction wiper switch
AUTO and sensitivity control
This sensor emits infrared rays through LED
and then detects the amount of rain drops
by receiving the rays reflected off the
sensing section (rain sensor mounting
section on the windshield) with photodiode.AUTO: Wiper operates automatically by rain
