VENTILATION, HEATING, AND AIR CONDITIONING SYSTEM
9-5
• The vehicle equiped with the DI engine has the supplementary heating
devices to increase the heating effect before the engine coolant fully
warms up. The supplementary heating devices are as follows:
-
FFH* (Fuel Fired Heater)
-
PTC (Positive Temperature Coefficient)
SUPPLEMENTARY HEATING DEVICE
FFH
*
This supplementary heater is a fuel burning type and
improves the heating effect by increasing the engine cool-
ant temperature.
Compared to PTC, FFH cannot be operated or stopped
by the driver. The FFH is automatically operated, de-
pending on conditions of the coolant temperature and
the ambient temperature.

X FFH Operation
• The FFH system operates up to more than 2 minutes
to burn the residual fuel inside the system when stop-
ping the engine during its operation. Therefore, a cer-
tain period of FFH operation after stopping the engine
is not a malfunction.
• In initial operating stage, the fuel pump generates the
operating sound and the FFH heater produces white
smoke. These are normal states to fill the fuel into the
FFH fuel line.
PTC
This supplementary heater is an electrical air heating
type and installed on the heater outlet port. This device
improves the heating effect by increasing the tempera-
ture of flowing air into the passenger room.
This device is operational/non-operational when the en-
gine control unit supplies/cuts off the voltage to the PTC
according to the coolant temperature and the ambient
temperature.
XX
XX
X Operational Condition
This device is activated when the blower switch is at
any position other than the “OFF” position and the cool-
ant temperature and the ambient temperature is within
a specified range.
XX
XX
X Non-operational Condition
• The blower switch is at the “OFF” position
• Defective ambient temperature sensor
• During engine cranking
• Battery voltage is too low
• During pre-glowing process (
indicator ON)
