Seat belt internal buzzer (chime) and warning lamp
The ignition is turned ON from OFF with the driver and passenger seat belts unbuckled.
The internal buzzer (chime) sounds and the warning lamp comes on for 6 seconds (T2).
(internal buzzer controlled by BCM, warning lamp controlled by instrument cluster) A.
B. Operation 1.
The ignition is turned ON from OFF with the driver and passenger seat belts unbuckled.
The internal buzzer (chime) does not sound but the warning lamp comes on for 6 seconds (T2).
(The seat belt reminder is operated when the vehicle is driven at 10 km/h (for EU), 25 km/h (for GEN)) C.
D. Operation 2.
When the fastened driver seat belt is unbuckled with IGN ON.
The internal buzzer (chime) sounds and the driver seat belt warning lamp comes on for T2 again. E.
F. Operation 3.
The ignition is turned OFF while the internal buzzer (chime) and seat belt warning lamp are activated.

8. SEAT BELT CONTROL
The driver seat belt is fastened while the internal buzzer (chime) and seat belt warning lamp are
activated.
The internal buzzer (chime) does not sound but the warning lamp comes on for the time remaining. I.
J. Operation 5.
When the seat belt reminder operation conditions are met during the warning, the seat belt reminder
is operated after stopping the warning output.
For the passenger seat, however, the system detects if the passenger seat is empty or occupied
and operates the warning lamp only for the first time. After that, the only seat belt reminder detects if
the passenger seat is occupied. -

Seat belt reminder operation
A
BIf the seat belt is fastened after the seat belt reminder is activated, the output of the reminder is
turned OFF immediately. The reminder will be operated again whenever the seat belt is
unbuckled.
CWhen the seat belt reminder is activated initially with the seat belt unbuckled, the internal buzzer
(chime) is turned ON for 0.02 seconds and then turned OFF for 1.18 seconds (this cycle
continues for 5 minutes) and the driver seat belt warning lamp on the instrument cluster remains
on.
DWhen the seat belt reminder is activated with the seat belt unbuckled, the internal buzzer (chime)
is turned ON for 0.02 seconds and then turned OFF for 1.18 seconds (this cycle continues for 5
minutes) and the passenger seat belt warning lamp on the instrument cluster remains on, after
detecting that the passenger seat is occupied through the input value of the passenger seat
occupancy sensor.
EWhen the vehicle speed is changed while the seat belt reminder is turned on, the internal buzzer
(chime) is operated as follows:
FPriority of internal buzzer (chime) operation
(Seat belt reminder > ignition key reminder > sunroof warning > tail lamp warning > hazard
warning flasher on > turn signal indicator)GEN
The seat belt reminder is operated when the
vehicle is driven at 25 km/h or more with IGN
ON and alternator in High status (engine
running), and driver seat belt is not fastened. If
the vehicle speed is decreased to less than 25
km/h within 5 minutes after the seat belt
reminder is activated, the internal buzzer
(chime) is turned off. If the vehicle speed is
increased to 25 km/h or more, the buzzer
signal is output for 5 minutes. Only EU If the driver and passenger seat belts are not
fastened with the ignition switch ON, engine
running, vehicle speed above 10 km/h and
any passenger occupied, the seat belt
reminder is activated. In addition, even though
the vehicle speed reduces to below 10 km/h
after the reminder is activated at speed of 10
km/h or higher, it will remain activated.

Room lamp cut off control
The lamp is turned off when entering sleep mode or in alarming status. A. Operation 1.
When the ignition is turned OFF (ignition key removed) with the room lamp switch ON, the room
lamp comes on for 10 minutes and then goes out automatically.
When the room lamp is turned off automatically, the room lamp automatic switching off signal is sent
to the instrument cluster before entering sleep mode. B.
C. Operation 2. (preventing battery discharge)
When the ACC is turned ON or ignition is turned ON with the ignition key inserted, the room lamp is
activated. D. Operation 3.
When the room lamp cut off operation is activated, the BCM sends cut off operation signal to the
instrument cluster through B-CAN to prevent the battery discharge. -

- IGN1 OFF, Smart key detected, Door openAny door except the driver door is opened and then closed.
The SKM starts to identify a smart key by using the interior antenna after confirming that all the doors
are closed through CAN communication with the BCM.
When no smart key is found, the SKM sends the smart key not detected warning signal to the BCM
and instrument cluster through B-CAN.
The BCM activates the buzzer for up to 10 seconds at intervals of 0.5 sec. ON/0.5 sec. OFF and
turns on the smart key warning indicator on the instrument cluster.
If a smart key is found, no operation is performed. 1.

(4) Smart key battery discharge warning (3) Smart key verification fail warning
When the verification is requested for ignition status change or engine starting and no verified smart key
is in the vehicle, the SKM sends the "smart key verification status" signal, which indicates that the
verification has failed, for up to 10 sec. until the verification fail conditions are deactivated. for up to 10
seconds. until the verification fail conditions are deactivated.
Verification fail detection and transmission conditions
When the ignition status is changed after a smart key is verified by the START/STOP switch ON
input, the SKM sends the verification status for 10 sec. -Normally, the smart key verification warning is one of the smart key fail conditions. -
Ignition status change
(OFF -> ACC) / (OFF -> IGN)/(ACC -> IGN) / (IGN -> engine ON) *
If above conditions are met again, the SKM re-verifies a smart key and sends the verification status
for another 10 seconds.
When the ignition status is changed by the transponder verification while the smart key status is sent
through the B-CAN, the SKM sends the smart key verification signal and also sends the transponder
verification signal for 10 seconds. -
-
If low smart key battery is detected during the verification process for ignition status change or engine
start, the SKM sends the signal for "smart key battery low voltage warning" to the BCM and instrument
cluster through the B-CAN for up to 10 sec. until the warning condition is deactivated.
Smart key battery discharge confirmation and deactivation
If the smart key battery low voltage is confirmed, the SKM sends the smart key battery low voltage
warning signal.
If the smart key battery is in normal condition, the SKM sends the smart key battery low voltage
warning deactivation signal.
The smart key is the last used key. -

(5) Transponder verification fail warning
If a verified smart key is not found by the key verification process, the SKM sends the information that
indicates the key is not verified to the instrument cluster through the B-CAN for up to 10 seconds until
the warning condition is deactivated.
The SKM sends the transponder verification warning when the verification has failed with the smart
key inserted into the immobilizer holder. -
Transponder verification fail detection and transmission conditions
When the ignition status is changed after the transponder is verified by the START/STOP switch ON
input, the SKM sends the transponder verification status for 10 sec. -
