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.

Make sure that the head restraints are in place and secured properly. Never drive the vehicle with
the head restraint removed.
To minimize the injuries in a collision or an abrupt stop, make sure the seatback is in the upright
position before driving. If the seatback is reclined too much, the occupant could slide under the seat
belt in a collision or an abrupt stop and cannot be protected properly by the air bag system.
3. CAUTIONS FOR POWER SEAT
You can operate the power seat with the ignition switch OFF. However, frequent operation of the
seat switch with the engine stopped can result in battery becoming discharged.
Operating more than one seat adjustment switch at the same time can cause damage to the seat
motor. Therefore, operate the seat switch only one at a time.
Do not use organic solvents such as benzene, thinner, alcohol or gasoline to prevent the seat cove
r
from being damaged while cleaning.
Do not operate the seat position adjustment switch forcefully when the seat does not move or it
contacts an object.
If the power seat is not operated, check and correct the problem before driving off.

Installation using rear seatback anchor
There are anchors (for hook mounting) for fixing child restraint system, on the back side of the rear
seatback as shown in the figure. -
Route the belt of the child restraint system over the seatback of the rear seat.
Attach the hook of the child restraint system belt to the anchor firmly, and securely tighten the child
