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.

5. PTC HEATER OPERATION PROCESS
1) PTC Heater Input/Output Factors
The engine ECU controls the PTC (Positive Temperature Coefficient) heater system by adjusting the
power supplied to the PTC system according to the two measured temperature values from the engine
coolant temperature sensor and HFM sensor. This system is mounted to the heater air outlet in the air
condition system module and heats the air which flows to the passenger room. Since the PTC system is
heated by the electrical power, the electric load and alternator capacity is greater than the conventional
one. The PTC is not operated when a) the engine is cranking, b) the battery voltage is below 11 V, c) the
glow plug is being preheated.
The ceramic PTC features that the resistance rises quickly in a certain temperature range. The PTC
heater has 3 circuits with power of 330 W. While only 1 circuit in the PTC heater is connected during
PTC1 operation, 2 circuits are connected during PTC2 or PTC3 operation.
