automatically regulate the amount of air flow. Next, dial
in the temperature you would like the system to maintain
by pressing the driver's or passenger's temperature con-
trol button. The rear temperature can only be adjusted
from the front when the ªREAR SYSTEMº knob on the
front ATC unit is in the ªAUTOº position. Once the
desired temperature is displayed, the system will achieve
and maintain 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:
² It is not necessary to move the temperature settings for
cold or hot vehicles. The system automatically adjusts
the temperature, mode and fan speed to provide
comfort as quickly as possible. ² The temperature can be displayed in U.S. or Metric by
selecting the US/M customer programmable feature.
Refer to the ªOverhead Console-Customer Program-
mable Featuresº in Section 3 of this manual.

remaining until the ªDELAYº is over will appear peri-
odically in the display. However, the fan will engage
immediately if the defrost mode is selected or by rotating
the blower control to any fixed blower speed.
This feature may be disabled using the following proce-
dure:
² Press and hold the Heated Rear Window and Auto LO
buttons for 5 seconds. UNDERSTANDING YOUR INSTRUMENT PANEL 209

Exhaust System
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.
Whenever a change is noticed in the sound of the exhaust
system, when exhaust fumes can be detected inside the
vehicle, or when the underside or rear of the vehicle is
damaged, have a competent mechanic inspect the com-
plete exhaust system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts. Open
seams or loose connections could permit exhaust fumes
to seep into the passenger compartment. In addition,
inspect the exhaust system each time the vehicle is raised
for lubrication or oil change. Replace as required. WARNING!Exhaust gases can injure or kill. They contain carbon
monoxide (CO) which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing CO, fol-
low the preceding safety tips. MAINTAINING YOUR VEHICLE 317
