How the System Works
URPA comes on automatically when the shift lever is
moved into REVERSE (R) and the vehicle speed is less
than 3 mph (5 km/h). When the system comes on,
the three lights on the display will illuminate to let you
know that the system is working. URPA senses
how close your vehicle is to an object. The distance is
determined by the four ultrasonic sensors located on the
rear bumper. When you shift into REVERSE (R) and
an object is detected, the following will occur in
sequence depending on the distance from the object:
·At 5 feet (1.5 m) a chime will sound and one
amber light will be lit;
·at 40 inches (1.0 m) both amber lights will be lit;
·at 20 inches (0.5 m) a continuous chime will
sound and all three lights (amber/amber/red) will
be lit; and
·at 1 foot (0.3 m) a continuous chime will sound and
all three lights (amber/amber/red) will ¯ash.
URPA can detect objects 3 inches (7.6 cm) and wider,
and at least 10 inches (25.4 cm) tall, but it cannot detect
objects that are above trunk level. In order for the
rear sensors to recognize an object, it must be within
operating range.If the URPA system is not functioning properly, the
display will ¯ash red, indicating that there is a problem.
The light will also ¯ash red while driving if a trailer is
attached to your vehicle, or a bicycle or object is on the
back of, or hanging out of your trunk. The light will
continue to ¯ash until the trailer or the object is
removed and your vehicle is driven forward at least
15 mph (25 km/h).
It may also ¯ash red if the ultrasonic sensors are not
kept clean. So be sure to keep your rear bumper free of
mud, dirt, snow, ice and slush or materials such as
paint or the system may not work properly. If after
cleaning the rear bumper and driving forward at least
15 mph (25 km/h), the display continues to ¯ash red, see
your dealer. For cleaning instructions, see
Cleaning
the Outside of Your Vehicle on page 5-86.
It may also ¯ash red if your vehicle is moving in
REVERSE (R) at a speed greater than 3 mph (5 km/h).
Other conditions that may affect system performance
include things like the vibrations from a jackhammer or
the compression of air brakes on a very large truck.
As always, drivers should use care when backing up a
vehicle. Always look behind you, being sure to check
for other vehicles, obstructions and blind spots.
3-25

When your vehicle is ®rst started, the display will show
the driver's temperature setting, the fan speed and
the air delivery mode.
When the ENG/MET (English/metric) button on the
Driver Information Center (DIC) is pressed, the display
will show readings in Fahrenheit or Celsius. Use the
ENG/MET button to toggle between them.
Manual Operation
SMODET:Pressing the MODE switch and changing
the mode cancels automatic operation and places the
system in manual mode. Press AUTO to return to
automatic operation.
To change the current mode, select one of the following:
G(Vent):This mode directs air to the instrument
panel outlets.
+(Bi-Level):This mode directs approximately half of
the air to the instrument panel outlets, and then
directs most of the remaining air to the ¯oor outlets.
Some air may be directed toward the windshield.
In automatic operation, cooler air is directed to the upper
outlets and warmer air to the ¯oor outlets.
8(Floor):This mode directs most of the air to the
¯oor outlets with some air directed to the outboard
outlets (for the side windows) a little air directed to the
windshield.
The MODE switch can also be used to select the
¯oor/defog mode. Information on defogging and
defrosting can be found later in this section.
y9z(Fan):Press this switch to increase or
decrease the fan speed. Pressing this switch cancels
automatic operation and places the system in manual
mode. Press AUTO to return to automatic operation.
If the air¯ow seems low when the fan speed is at
the highest setting, the passenger compartment air ®lter
may need to be replaced. For more information, see
Passenger Compartment Air Filter on page 3-35andPart A: Scheduled Maintenance Services on
page 6-4.
?(Recirculation):This mode keeps outside air
from coming in the vehicle. It can be used to prevent
outside air and odors from entering your vehicle or
to help heat or cool the air inside your vehicle more
quickly. Press this button to turn the recirculation mode
on or off. When the button is pressed, an indicator
light will come on. The air-conditioning compressor also
comes on.
3-29

TEMP (Driver's Temperature Knob):Press this knob
to turn the climate control system on or off. Turn this
knob clockwise or counterclockwise to manually
increase or decrease the temperature inside your
vehicle.
TEMP (Passenger's Temperature Knob):Press this
knob to turn the passengers' climate control system
controls on or off. Turn this knob to manually increase
or decrease the temperature for the front passenger.
If the passenger's climate controls are turned off,
the driver's temperature knob will control the
temperature for the entire vehicle.
A/C (Air Conditioning):Press this button to override
the automatic system and turn the air-conditioning
system on or off. When in AUTO the air-conditioning
compressor will come on automatically, as necessary.
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for your vehicle to cool down. It also helps
the system to operate more efficiently.For quick cool down on hot days:
1. Select the vent mode.
2. Select the recirculation mode.
3. Select A/C.
4. Select the coolest temperature.
5. Select the highest fan speed.
6. Open all outlets.
Using these settings together for long periods of time
may cause the air inside your vehicle to become too dry.
To prevent this from happening, after the air in your
vehicle has cooled, turn the recirculation mode off.
The air-conditioning system removes moisture from the
air, so you may sometimes notice a small amount of
water dripping underneath your vehicle while idling
or after turning off the engine. This is normal.
If your vehicle has the memory option, it can be used to
recall your climate control settings. For more information,
see
Climate Controls Personalization on page 3-36.
3-30

Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
(moisture) condensing on the cool window glass. This
can be minimized if the climate control system is
used properly. There are two modes to clear fog from
your windshield. Use the ¯oor/defog mode to clear
the windows of fog or moisture and warm the
passengers. Use the defrost mode (FRONT) to remove
fog or frost from the windshield more quickly.
SMODET:Press this switch until ¯oor/defog
appears on the display.
/(Floor/Defog):This mode directs the air equally
between the windshield and the ¯oor outlets. When you
select this mode, the system turns off recirculation
and runs the air-conditioning compressor unless
the outside temperature is at or below freezing. The
recirculation mode cannot be selected while in the
¯oor/defog mode.
1FRONT (Defrost):Pressing FRONT directs most of
the air to the windshield and the side window outlets, with
some air directed to the ¯oor outlets. In this mode, the
system will automatically turn off recirculation and run the
air-conditioning compressor, unless the outside
temperature is at or below freezing. Recirculation cannot
be selected while in the defrost mode. Do not drive the
vehicle until all the windows are clear.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
The rear window defogger will only work when the
ignition is in ON.
=REAR:Press this button to turn the rear window
defogger on or off. Be sure to clear as much snow from
the rear window as possible.
The rear window defogger will turn off approximately 10
minutes after the button is pressed. If turned on
again, the defogger will only run for approximately ®ve
minutes before turning off. The defogger can also
be turned off by pressing the button again or by turning
off the engine.
The heated outside rearview mirrors will heat to help
clear fog or frost from the surface of the mirror when the
REAR button is pressed.
Notice:Don't use a razor blade or something else
sharp on the inside of the rear window. If you
do, you could cut or damage the defogger and the
repairs would not be covered by your warranty.
Do not attach a temporary vehicle license, tape, a
decal or anything similar to the defogger grid.

This light should come on, as a check to show you it is
working, when the ignition is on and the engine is
not running. If the light does not come on, have it
repaired. This light will also come on during a
malfunction in one of two ways:
·Light FlashingÐ A mis®re condition has been
detected. A mis®re increases vehicle emissions
and may damage the emission control system on
your vehicle. Diagnosis and service may be
required.
·Light On SteadyÐ An emission control system
malfunction has been detected on your vehicle.
Diagnosis and service may be required.
If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
·Reducing vehicle speed.
·Avoiding hard accelerations.
·Avoiding steep uphill grades.
·If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible.
If the light stops ¯ashing and remains on steady, see ªIf
the Light Is On Steadyº following.If the light continues to ¯ash, when it is safe to do so,
stop the vehicle.Find a safe place to park your vehicle.
Turn the key off, wait at least 10 seconds and restart
the engine. If the light remains on steady, see ªIf
the Light Is On Steadyº following. If the light is still
¯ashing, follow the previous steps, and see your dealer
for service as soon as possible.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully install
the cap. See
Filling Your Tank on page 5-6. The
diagnostic system can determine if the fuel cap has
been left off or improperly installed. A loose or missing
fuel cap will allow fuel to evaporate into the atmosphere.
A few driving trips with the cap properly installed
should turn the light off.
Did you just drive through a deep puddle of water?
If so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out. A few driving trips should turn the light off.

CHECK TIRE PRESSURE ± 144:This message is
displayed when the Tire Pressure Monitor (TPM) system
detects a low or high tire pressure condition in one or
more of the road tires. By pressing the INFO button
up or down, the DIC display will show which tire or tires
do not have the correct in¯ation pressure. A ªLOW
TIREº condition exists when the tire's air pressure is
under 25 psi (172 kPa) and a ªHIGH TIREº condition
exists when the tire's air pressure is above 38 psi
(262 kPa). The system will display the air pressure, the
tire location (LF, RF, RR or LR) and if the air pressure
is low or high. The tire pressure information is available
in English or metric measurements. For example, a
driver's side front tire that is low may be shown
as: 22 PSI LF TIRE LOW.
The correct tire in¯ation pressure should be set to those
shown on the Tire Loading-Information Label, located
on the rear edge of the driver's door. For more
information regarding proper tire in¯ation, see
In¯ation -- Tire Pressure on page 5-64. If a tire is low,
you should stop as soon as possible and inspect
your tire(s) for damage. If a tire is ¯at, see
If a Tire Goes
Flat on page 5-73.Once the TPM system detects the low or high tire
pressure condition, the message CHECK TIRE
PRESSURE will be displayed whenever you start the
engine. To remove or clear the CHECK TIRE
PRESSURE message, you will need to set the tire(s) to
the proper tire pressure. See
In¯ation -- Tire Pressure
on page 5-64.
{CAUTION:
When the CHECK TIRE PRESSURE message is
displayed on the Driver Information Center and
the tire pressure is low, your vehicle's
handling capabilities will be reduced during
severe maneuvers. If you drive too fast, you
could lose control of your vehicle. You or
others could be injured. Don't drive over 55
mph (90 km/h) when the tire pressure is low.
Drive cautiously and correct the tire pressure
as soon as you can.

CHECK WASHER FLUID ± 25:This message means
that your vehicle is low on windshield washer ¯uid.
See
Windshield Washer Fluid on page 5-39.
DRIVER DOOR AJAR ± 140:This message will
display anytime the key is in ON, the transaxle is not in
PARK (P) and the driver's door is open or ajar. A
chime will sound when the vehicle's speed is greater
than 3 mph (4.8 km/h).
DRIVE NO. X (1 OR 2):This message will be displayed
with the key in ON and while entering FEATURE
PROGRAMMING, but only if the vehicle is equipped
with memory seats. The message will show which driver
is activating the personalization feature. It will only
stay on for ®ve seconds. This message can be
customized for you by your dealer.
ENGINE COOLANT HOT, IDLE ENGINE ± 44:This
message will appear when the engine coolant
temperature is over 262ÉF (128ÉC). Stop and allow your
vehicle to idle in PARK (P) until it cools down and the
message is removed. Do not increase engine speed
above a normal idle. If it does not cool down, turn off the
engine and have it serviced before driving it again.
Severe engine damage can result from an overheated
engine. See
Engine Overheating on page 5-28.ENGINE HOT±AC OFF ± 16:This message displays
when the engine coolant becomes hotter than the normal
operating temperature. To avoid added strain on a hot
engine, the air conditioning compressor is automatically
turned off. When the coolant temperature returns to
normal, the A/C operation will automatically resume. You
can continue to drive your vehicle. If this message
continues to appear, have the system repaired as soon
as possible to avoid compressor damage.
ENGINE OVERHEATED, STOP ENGINE ± 42:This
message will appear when the engine has overheated.
Stop and turn the engine off immediately to avoid
severe engine damage. See
Engine Overheating on
page 5-28. A multiple chime will also sound when this
message is displayed.
ENGINE POWER REDUCED ± 41:This message
informs you that the vehicle is reducing engine power
because the transaxle is being placed in gear under
conditions that may cause damage to the vehicle's
engine, transaxle or ability to accelerate.
FUEL LEVEL LOW ± 11:This message serves as a
warning that the fuel level in the tank is critically
low. Stop for fuel soon. A single chime will sound when
this message is displayed.
