Description
The heater core is located in the HVAC housing. The heater core is a heat exchanger made of rows of tubes with
fins and is positioned within the air distribution housing so that only the selected amount of air entering the housing
passes through the heater core before it is distributed through the heating-A/C system ducts and outlets. One end of
the heater core is fitted with a tank that includes the fittings for the heater core tubes. The heater core can only be
serviced by removing the HVAC housing from the vehicle.
Operation
Engine coolant is circulated through the heater hoses to the heater core at all times. As the coolant flows through the
heater core, heat is removed from the engine and is transferred to the heater core tubes and fins. Air directed
through the heater core picks up the heat from the heater core fins. The blend-air door allows control of the heater
output air temperature by regulating the amount of air flowing through the heater core. The blower motor speed con-
trols the volume of air flowing through the HVAC housing.
Removal & Installation
1. Drain the cooling system (See Cooling System Draining Procedure in Section 06 Cooling System).
2. Evacuate the A/C system (See A/C System Evacuation and Recharge in Section 13 Heating & Air Conditioning).
3. Remove the HVAC housing assembly and place it on a workbench (See HVAC Housing Removal & Installationin Section 13 Heating & Air Conditioning).
4. Remove the retaining bolts and clamps.
5. Remove the heater core.
6. Installation is in the reverse order of removal.
Installation Notes:
• Verify the cooling system is filled to proper specifications.

Description
Available occupant restraints for this vehicle include both active and passive types. Active restraints are those which
require the vehicle occupants to take some action to employ, such as fastening a seat belt; while passive restraints
require no action by the vehicle occupants to be employed.
Active Restraints
•Front Seat Belts
• Rear Seat Belts
Passive Restraints
• Driver Airbag
• Passenger Airbag
• Seat Belt Tensioners
Operation
Active Restraints
The primary passenger restraints are the seat belts. Seat belts are referred to as an active restraint because the
vehicle occupants are required to physically fasten and properly adjust these restraints in order to benefit from them.
Passive Restraints
The passive restraints are referred to as a supplemental restraint system because they were designed and are
intended to enhance the protection for the occupants of the vehicle only when used in conjunction with the seat belts.
They are referred to as passive restraints because the vehicle occupants are not required to do anything to make
them operate; however, the vehicle occupants must be wearing their seat belts in order to obtain the maximum safety
benefit from the supplemental restraint system.
The supplemental restraint system electrical circuits are continuously monitored and controlled by a microprocessor
and software contained within the Restraints Control Module (RCM). An airbag indicator in the instrument cluster
illuminates for about seven seconds as a bulb test each time the ignition switch is turned to the ON or START posi-
tions. Following the bulb test, the airbag indicator is turned ON or OFF by the RCM to indicate the status of the
supplemental restraint system. If the airbag indicator comes ON at any time other than during the bulb test, it indi-
cates that there is a problem in the supplemental restraint system electrical circuits. Such a problem may cause
airbags not to deploy when required, or to deploy when not required.
Deployment of the supplemental restraints depends upon the angle and severity of an impact. When an impact is
severe enough, the microprocessor in the RCM signals the inflator of the appropriate airbag units to deploy their
airbag cushions. The front seat belt tensioners are provided with a deployment signal by the RCM in conjunction with
the front airbags.
