improve window clearing operation. Recirculation will
be disabled automatically if these modes are selected.
Rear Automatic Temperature Control — If
Equipped
The Rear Automatic Temperature Control System has
floor air outlets to the rear of the right side sliding door
and overhead outlets at each outboard rear seating
position. The system provides heated air through the
floor outlets or cool, dehumidified air through the head-
liner outlets. The “REAR SYSTEM” knob for the Rear Automatic
Temperature Control System is on the front ATC control
unit located on the instrument panel.
Selecting the “AUTO” position for the Rear Automatic
Temperature Control System from the front ATC control
unit, illuminates a “LOCK” symbol in the rear display.
The rear temperature and air source are controlled from
the front ATC control unit.
The “REAR SYSTEM” knob on the front ATC control unit
has three positions, “REAR CONTROL”, “OFF”, and
“AUTO”. Only when the “REAR SYSTEM” knob is in the
“REAR CONTROL” position do the second seat occu-
pants have control of the Rear Automatic Temperature
Control System.
The Rear Automatic Temperature Control System is
located in the headliner near the center of the vehicle.296 UNDERSTANDING YOUR INSTRUMENT PANEL

Operation of the rear system is quite simple. Begin by
rotating the rear system center control knob on the front
ATC control unit to the “REAR CONTROL” position, this
illuminates an “UNLOCK” symbol in the rear display.
Next, rotate the Rear Blower Control and the Rear Mode
Control to the “AUTO” positions. Select the temperature you would like the system to maintain by pressing the
Rear Temperature Control button. Once the desired tem-
perature is displayed, the system will achieve and main-
tain that comfort level automatically. When the system is
set up for your comfort level, it is not necessary to change
the settings. You will experience the greatest efficiency by
simply allowing the system to function automatically.
NOTE:

If your vehicle is equipped with Infrared Three-Zone
Automatic Temperature Control the rear defroster sym-
bol will show in the display screen when the rear
window defroster is on.
CAUTION!To avoid damaging the electrical conductors of the
rear window defroster, do not use scrapers, sharp
instruments, or abrasive window cleaners on the
interior surface of the window.

Service Tire System Soon
The Tire Pressure Monitoring Telltale Lamp will flash on
and off for 60 seconds in the instrument cluster, and an
audible chime will be activated when one or more of the
four active road tire pressures are low.
In addition the Electronic Vehicle Information Center
(EVIC) will display a “SERVICE TIRE SYSTEM SOON”
text message. The flash cycle will repeat every ten
minutes, without an audible chime, until the condition no
longer exists. The flash cycle sequence will repeat and an
audible chime will sound once every ignition cycle for
each condition that it detects.
NOTE: If a temporary spare tire is in use and none of
the remaining 3 active road tire pressures are low, a
“SERVICE TIRE SYSTEM SOON textual message will
appear in the EVIC after 10 minutes of driving, CAUTION!The Tire Pressure Monitoring System (TPMS) has
been optimized for the original equipment tires and
wheels. TPMS pressures have been established for
the tire size equipped on your vehicle. Undesirable
system operation or sensor damage may result when
using replacement equipment that is not of the same
size, type, and/or style. After-market wheels can
cause sensor damage. Do not use tire sealant from a
can, or balance beads if your vehicle is equipped
with a Tire Pressure Monitor System, as damage to
the sensors may result. STARTING AND OPERATING 351

ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated onboard
diagnostic system called OBD II. This system monitors
the performance of the emissions, engine, and automatic
transmission control systems. When these systems are
operating properly, your vehicle will provide excellent
performance and fuel economy, as well as engine emis-
sions well within current government regulations.
If any of these systems require service, the OBD II system
will turn on the “Malfunction Indicator Light.” It will
also store diagnostic codes and other information to
assist your service technician in making repairs. Al-
though your vehicle will usually be drivable and not
need towing, see your dealer for service as soon as
possible. CAUTION!• Prolonged driving with the “Malfunction Indica-
tor Light” on could cause further damage to the
emission control system. It could also affect fuel
economy and driveability. The vehicle must be
serviced before any emissions tests can be per-
formed.
• If the “Malfunction Indicator Light” is flashing
while the engine is running, severe catalytic con-
verter damage and power loss will soon occur.
Immediate service is required.
Loose Fuel Filler Cap Message
After fuel is added, the vehicle diagnostic system can
determine if the fuel filler cap is loose, improperly
installed, or damaged. A loose fuel filler cap message will
be displayed in the instrument cluster. Tighten the gas416 MAINTAINING YOUR VEHICLE
