Automatic Operation
1. Press the AUTO button on the Automatic
Temperature Control (ATC) Panel.
2. Next, adjust the temperature you would like
the system to maintain by adjusting the driver
and front passenger temperature control but-
tons. Once the desired temperature is dis-
played, the system will achieve and automati-
cally maintain that comfort level.
3. 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 auto-
matically.
NOTE:
•
It is not necessary to move the tempera-
ture settings for cold or hot vehicles. The
system automatically adjusts the tem-
perature, mode and fan speed to provide
comfort as quickly as possible.
• The temperature can be displayed in U.S.
or Metric units by selecting the US/M
customer-programmable feature. Refer to
the “Electronic Vehicle Information Cen-
ter (EVIC) — Customer-Programmable
Features (SETUP)” in this section of the
manual.

HAZARD WARNING FLASHERSThe Hazard Warning flasher switch is located
on the switch bank just above the climate
controls.Press the switch to turn on the Hazard
Warning flasher. When the switch is
activated, all directional turn signals will
flash on and off to warn oncoming
traffic of an emergency. Press the switch a
second time to turn off the Hazard Warning
flashers.
This is an emergency warning system and it
should not be used when the vehicle is in
motion. Use it when your vehicle is disabled
and it is creating a safety hazard for other
motorists.
When you must leave the vehicle to seek assis-
tance, the Hazard Warning flashers will con-
tinue to operate even though the ignition is
placed in the OFF position.
NOTE:
With extended use the Hazard Warning
flashers may wear down your battery.IF YOUR ENGINE OVERHEATSIn any of the following situations, you can
reduce the potential for overheating by taking
the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, place the
transmission in NEUTRAL, but do not in-
crease the engine idle speed.
NOTE:
There are steps that you can take to slow
down an impending overheat condition:
• If your air conditioner (A/C) is on, turn it
off. The A/C system adds heat to the
engine cooling system and turning the
A/C off can help remove this heat.
• You can also turn the temperature control
to maximum heat, the mode control to
floor and the blower control to high. This
allows the heater core to act as a supple-
ment to the radiator and aids in removing
heat from the engine cooling system.CAUTION!
Driving with a hot cooling system could dam-
age your vehicle. If the temperature gauge
reads HOT (H), pull over and stop the vehicle.
Idle the vehicle with the air conditioner turned
off until the pointer drops back into the normal
range. If the pointer remains on HOT (H), and
you hear continuous chimes, turn the engine
off immediately and call for service.
WARNING!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam coming
from under the hood, do not open the hood
until the radiator has had time to cool. Never
try to open a cooling system pressure cap
when the radiator or coolant bottle is hot.

CAUTION!
•
When installing the totally integrated power
module cover, it is important to ensure the
cover is properly positioned and fully
latched. Failure to do so may allow water to
get into the totally integrated power module
and possibly result in a electrical system
failure.
(Continued)
CAUTION!(Continued)
• When replacing a blown fuse, it is important
to use only a fuse having the correct am-
perage rating. The use of a fuse with a
rating other than indicated may result in a
dangerous electrical system overload. If a
properly rated fuse continues to blow, it
indicates a problem in the circuit that must
be corrected.
VEHICLE STORAGEIf you are leaving your vehicle dormant for more
than 21 days you may want to take steps to
protect your battery. You may:
•Remove fuse #J13 in the Totally Integrated
Power Module (TIPM) labeled Ignition-Off
Draw (IOD#1).
• Or, disconnect the negative cable from the
battery.
