WARNING LIGHTS AND CHIMES
Warning lights and gauges can alert you to a vehicle condition that may
become serious enough to cause expensive repairs. A warning light may
illuminate when a problem exists with one of your vehicle's functions.
Many lights will illuminate when you start your vehicle to make sure the
bulb works.If any light remains on after starting the vehicle, have
the respective system inspected immediately.
Check engine
Illuminates briefly to ensure the
system is functional. If it comes on
after the engine is started, one of
the engine's emission control
systems may be malfunctioning. The
light may illuminate without a driveability concern being noted and will
not require towing.
Light remains on:
Temporary malfunctions may cause your light to illuminate. Examples
are:
1. The vehicle has run out of fuel.
2. Poor fuel quality or water in the fuel.
3. The fuel cap may not have been properly installed and securely
tightened.
These temporary malfunctions can be corrected by filling the fuel tank
with high quality fuel of the recommended octane and/or properly
installing and securely tightening the fuel cap. After three driving cycles
without these or any other temporary malfunctions present, the light

ELECTRONIC AUTOMATIC TEMPERATURE CONTROL (EATC)
SYSTEM
The EATC system will maintain a
selected temperature and
automatically control the fan speed
and airflow location.
Automatic operation
Press AUTOMATIC and select the desired temperature. The selected
temperature and the word AUTO will appear in the display window. The
EATC system will either heat or cool to achieve the selected
temperature. The system will automatically determine fan speed, airflow
location and if outside air or recirculated air is required. Fan speed
remains automatic unless the fan speed thumbwheel is turned or the
steering wheel fan speed control (if equipped) is pressed.
When in automatic operation and weather conditions require heat, the
air will be sent to the floor ducts. However, until the engine has warmed,
the fan will operate at a low speed and airflow will be directed to the
windshield defroster ducts. Upon engine warm up, the system will
automatically direct airflow to the floor ducts and operate the required
fan speed to achieve the selected temperature.
If unusual conditions exist (i.e.-window fogging, etc.), the manual
overrides allow you to select airflow locations and the fan speed. To
return to automatic operation, press Automatic/AUTO.
Temperature selection

If a manual override function is selected while the outside temperature is
displayed, the new function will be displayed for four seconds after it is
changed, then the outside temperature will return to the window along
with the override selection.
The outside temperature reading is most accurate when the vehicle is
moving. Higher readings may be obtained when the vehicle is not
moving. The readings that you get may not agree with temperatures
given on the radio due to differences in vehicle and station locations.
Fan speed (
)
When AUTOMATIC is pressed, fan
speed is adjusted automatically for
existing conditions. You can override
fan speed at any time. To control
fan speed manually, use the
thumbwheel to cancel automatic fan
speed operation. Rotate the
thumbwheel or press the steering
wheel controls (if equipped) up for
higher fan speed or down for lower
fan speed.
The display will show
to
indicate manual fan operation.
To return to automatic fan operation, press AUTOMATIC.
Manual override controls
The manual override controls allow
you to determine airflow location
and fan speed. To return to full
automatic control, press
Automatic/AUTO.
²Max A/C - Distributes recirculated air through the instrument panel
registers. A temperature of 16ÉC (60ÉF) will appear in the display
window until Automatic/AUTO, another manual override control, or
the temperature control has been selected. The A/C compressor will
only function if the outside temperature is above approximately 2ÉC
(36ÉF). Max A/C is noisier than Norm A/C, but more economic and
efficient. This mode will reduce undesirable odors from entering the
vehicle.

²Norm A/C- Distributes outside air through the instrument panel
registers. The A/C compressor will only function if the outside
temperature is above approximately 2ÉC (36ÉF). Norm A/C is more
quiet than Max A/C, but not as economic and efficient.
²Vent-Distributes outside air through the instrument panel registers.
The air cannot be cooled below the outside temperature.
²Floor- Distributes outside air through the floor ducts. The air cannot
be cooled below the outside temperature.
²Floor & Defrost - Distributes outside air through the windshield
defroster ducts, floor ducts and the side window demisters. The A/C
compressor will operate automatically if the outside temperature is
above approximately 2ÉC (36ÉF). The air distributed through the floor
ducts will be slightly warmer than that sent to the windshield
defroster ducts and the side window demisters.
²Defrost - Distributes outside air through the windshield defroster
ducts and the side window demisters. The A/C compressor will
operate automatically if the outside temperature is above
approximately 2ÉC (36ÉF). This mode will clear ice and fog from the
windshield.
Operating tips
²To reduce fogging under humid weather conditions, place the climate
control system in Defrost and Rear Defrost (if equipped) mode before
driving.
²To reduce humidity buildup inside the vehicle: Do not drive with the
climate control system in Off mode. Do not drive with the climate
control system in Max A/C mode (if equipped).
²Under normal weather conditions, do not leave your vehicle in Max
A/C (if equipped), recirculation control (if equipped) or Off mode
when turning off the ignition.
²Under snowy or dirty weather conditions, leave your vehicle in Max
A/C (if equipped), recirculation control (if equipped), or Off mode
when turning off the ignition.
²Remove any snow, ice or leaves from the exterior base of the
windshield.
²To increase the efficiency of the A/C (if equipped), drive with the
windows slightly open for 2±3 minutes or until the vehicle has been
ªairedº out.
²Do not place objects under the front seat or over the defroster ducts.
They may reduce visibility, fall into the ducts, or degrade the
performance of your climate control system.

section for more details.
4. The overhead console displays the compass heading in one of eight
directions: NORTH, NORTHEAST, EAST, SOUTHEAST, SOUTH,
SOUTHWEST, WEST, and NORTHWEST.
Zone variation mode
Most geographic areas (zones) have a magnetic north compass point that
varies slightly from the northerly direction on maps. A correct zone
setting will eliminate compass heading error.
For optimum calibration, turn off all electrical accessories (heater/air
conditioning, wipers, etc.) and make sure all vehicle doors are shut.
To set the compass zone:
1. Press and release the MODE
button until the compass directional

SAFETY RESTRAINTS
Personal Safety System
The Personal Safety System provides an improved overall level of frontal
crash protection to front seat occupants and is designed to help further
reduce the risk of air bag-related injuries. The system is able to analyze
different occupant conditions and crash severity before activating the
appropriate safety devices to help better protect a range of occupants in
a variety of frontal crash situations.
Your vehicle's Personal Safety System consists of the following items:
²Driver and passenger dual-stage air bag supplemental restraints
²Driver and front passenger side air bags
²Front safety belts with pretensioners, energy management retractors,
and safety belt usage sensors
²Driver's seat position sensor
²Passenger occupant classification sensor
²Front crash severity sensor
²Restraints Control Module (RCM) with impact and safing sensors
²Restraint system warning light and back-up tone
²The electrical wiring for the air bags, crash sensor(s), safety belt
pretensioners, front safety belt usage sensors, driver seat position
sensor, passenger occupant classification sensor, and indicator lights
How does the personal safety system work?
The Personal safety system can adapt the deployment strategy of your
vehicle's safety devices according to crash severity and occupant
conditions. A collection of crash and occupant sensors provides
Seating and Safety Restraints
91

information to the Restraints control module (RCM). During a crash, the
RCM activates the safety belt pretensioners and/or either one or both
stages of the dual-stage air bag supplemental restraints based on crash
severity and occupant conditions.
The fact that the pretensioners or air bags did not activate for both front
seat occupants in a collision does not mean that something is wrong with
the system. Rather, it means the Personal safety system determined the
accident conditions (crash severity, belt usage, etc.) were not
appropriate to activate these safety devices. Front air bags and
pretensioners are designed to activate only in frontal and near-frontal
collisions, not rollovers, side-impacts, or rear-impacts unless the collision
causes sufficient longitudinal deceleration.
Driver and passenger dual-stage air bag supplemental restraints
The dual-stage air bags offer the capability to tailor the level of air bag
inflation energy. A lower, less forceful energy level is provided for more
common, moderate-severity impacts. A higher energy level is used for
the most severe impacts. Refer toAir bag supplemental restraints
section in this chapter.
Front crash severity sensor
The front crash severity sensor enhances the ability to detect the
severity of an impact. Positioned up front, it provides valuable
information early in the crash event on the severity of the impact. This
allows your Personal safety system to distinguish between different levels
of crash severity and modify the deployment strategy of the dual-stage
air bags and safety belt pretensioners.
Driver's seat position sensor
The driver's seat position sensor allows your Personal safety system to
tailor the deployment level of the driver dual-stage air bag based on seat
position. The system is designed to help protect smaller drivers sitting
close to the driver air bag by providing a lower air bag output level.
Passenger occupant classification sensor (OCS)
For air bags to do their job they must inflate with great force, and this
force can pose a potentially deadly risk to occupants that are very close
to the air bag when it begins to inflate. For some occupants, this occurs
because they are initially sitting very close to the air bag. For other
occupants, this occurs when the occupant is not properly restrained by
seat belts or child safety seats and they move forward during pre-crash
braking. The most effective way to reduce the risk of unnecessary
