Ultrasonic Rear Parking Assist
(URPA) (Option)
Ultrasonic Rear Parking Assist can help you to
determine how close an object is to your rear bumper
within a given area, making parking easier.
The URPA display is
located inside the vehicle,
above the rear window.
It has three color
-coded
lights that can be seen
through the rearview mirror
or by turning around.
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 shifting into REVERSE (R) and an
object is detected, one of the following will occur:

2-119
A chime will sound the first time an object is detected.
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 flash red, indicating that there is a problem.
The light will also flash 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 flash until the trailer or the object is
removed and your vehicle is driven forward at least
15 mph (25 km/h). It may also flash 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 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 flash
red, see your dealer. It may also flash 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. For
cleaning instructions, see ªCleaning Your Vehicleº in
the Index.

Outside Temperature Display
The outside temperature is always displayed when your
vehicle is running. You can change it from Fahrenheit to
Celsius by pressing the ENG/MET (English/metric)
button on the left side of the instrument panel cluster.
The outside temperature sensor is located near the front
grille. The sensor can be affected by road or engine heat
during idling, slow driving or when the engine is first
started after a short trip. In order to ensure proper
automatic climate control operation, the outside air
temperature display may not update as quickly as
expected. This is to allow the air surrounding the outside
temperature sensor to be as close to the actual outside
conditions as possible. This is determined by how much
time has elapsed since the vehicle has been turned off
and by vehicle speed.
Mode Button
Press the MODE button to deliver air through the floor,
middle or windshield outlets. The system will stay in the
selected mode until the MODE button is pressed again.
Press the up or down arrow to cycle through the
available modes.Automatic Operation
When the system is set for automatic operation, sensors
will control the air delivery mode. Air will come from
the floor, middle or windshield outlets. The fan speed
will vary as the system maintains the selected
temperature setting.
Be careful not to put anything over the solar sensor
located in the middle of the instrument panel near the
windshield. This sensor is used by the automatic system
to regulate temperature.
To find your comfort zone, start with the 75
F (24
C)
setting and allow about 30 minutes for the system to
regulate. Turn the knob to adjust the temperature if
necessary. If you choose 60
F (16
C), the system will
remain at that maximum cooling setting and will not
regulate fan speed. If you choose the temperature of
90
F (32
C), the system will remain at that maximum
heating setting and will not regulate fan speed. Choosing
either maximum setting will not cause the system to heat
or cool any faster.

3-6 Electronic Solar Sensor
The sensor monitors the sun's solar radiation and is
located on top of the instrument panel near the
windshield. The ECC panel uses this information to
automatically make the necessary temperature and
airflow adjustments to maintain your comfort.
Air Conditioning
On hot days, open the windows long enough to let hot
inside air escape. This reduces the time it takes for your
vehicle to cool down. Then keep your windows closed
for the air conditioner to work its best.
Press the AUTO button or the TEMP knob to turn the
system on. The system will cool and dehumidify the air
inside the vehicle. Also while in the AUTO mode, the
system will use recirculation as necessary to cool the air.
You may also need to adjust the interior temperature and
the fan speed as needed.
Heating
Press the MODE button to select heater. Adjust the
interior temperature to a comfortable level and if the fan
speed needs adjusting, press the up or down arrow.
Outside air will be brought in and sent through the floor,
air conditioning or bi
-level outlets (depending on the
condition). The heater works best if you keep your
windows closed while using it.

When to Check
Check your tires once a month or more.
Don't forget your compact spare tire. It should be
at 60 psi (420 kPa).
How to Check
Use a good quality pocket
-type gage to check tire
pressure. You can't tell if your tires are properly inflated
simply by looking at them. Radial tires may look
properly inflated even when they're underinflated.
Be sure to put the valve caps back on the valve
stems. They help prevent leaks by keeping out dirt
and moisture.
Tire Pressure Monitor (TPM) System
(If Equipped)
The Tire Pressure Monitor (TPM) system uses radio
and sensor technology to check tire pressure levels.
Sensors, mounted on each road wheel, transmit tire
pressure readings to a receiver located in the trunk.
Tire pressure status and tire pressure warnings are
shown on the Driver Information Center (DIC) display.
See ªDriver Information Center (DIC)º in the Index
for details regarding DIC controls and displays.
The system operates on a radio frequency subject to
Federal Communications Commission (FCC) Rules
and with Industry and Science Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) this device may not cause harmful interference,
and (2) this device must accept any interference
received, including interference that may cause
undesired operation.
This device complies with RSS
-210 of Industry
and Science Canada. Operation is subject to the
following two conditions: (1) this device may not
cause interference, and (2) this device must accept any
interference received, including interference that may
cause undesired operation of the device.

6-49
Changes or modifications to this system by other than an
authorized service facility could void authorization to
use this equipment.
If the TPM system detects low tire pressure, below
24 psi (165 kPa), or high tire pressure, above 36 psi
(248 kPa), a message, CHECK TIRE PRESSURE, will
appear on the Driver Information Center (DIC) display.
By pressing the INFO button, the DIC screen will show
which tire(s) has the low or high pressure condition.
See ªInflation
-- Tire Pressureº in the Index for
information regarding correct tire inflation. If a tire is
low, you should stop as soon as possible and check all
your tires for damage. If a tire is flat, see ªIf a Tire
Goes Flatº in the Index.
NOTICE:
Do not use a tire sealant if your vehicle is equipped
with Tire Pressure Monitors. The liquid sealant
can damage the tire pressure monitor sensors.
Once a low or high tire pressure condition is detected,
the TPM system will display the CHECK TIRE
MESSAGE each time the engine is started, until the
tire(s) are set to the correct inflation pressure. The Certification/Tire Label, which is located on the
rear edge of the driver's side rear door, shows the
correct inflation pressure for the tires on your vehicle.
The TPM system also allows the driver to check the
air pressure status of each road tire using the Driver
Information Center (DIC). Each tire's air pressure will be
listed individually, in the following order: LF (left front
or driver's side front tire), RF (right front or passenger's
side front tire), RR (right rear or passenger's side
rear tire) and LR (left rear or driver's side rear tire).
See ªInflation
-- Tire Pressureº in the Index for
information regarding correct tire inflation. Also, see
ªDriver Information Center (DIC)º in the Index for
information on the DIC controls and displays.
If the DIC display doesn't show tire pressures or the
SERVICE TPM SYSTEM message appears, see your
dealer for service. The TPM system may not work
properly while the compact spare tire is installed.
Anytime you replace one or more tires or rotate your
tires the TPM system will need to be reset. A special
tool is needed to reset the sensor identification codes.
See your dealer for service.
The TPM system can alert you about a low or high
tire pressure condition, but it doesn't replace normal
tire maintenance. See ªTiresº in the Index.

6-50 Tire Inspection and Rotation
Tires should be rotated every 6,000 to 8,000 miles
(10 000 to 13 000 km). Any time you notice unusual
wear, rotate your tires as soon as possible and check
wheel alignment. Also check for damaged tires or
wheels. See ªWhen It's Time for New Tiresº and
ªWheel Replacementº later in this section for
more information.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The first
rotation is the most important. See ªScheduled
Maintenance Servicesº in the Maintenance Schedule
booklet for scheduled rotation intervals.
When rotating your tires, always use the correct rotation
pattern shown here.Don't include the compact spare tire in your tire rotation.
After the tires have been rotated, adjust the front and
rear inflation pressures as shown on the Tire
-Loading
Information label. Vehicles equipped with the Tire
Pressure Monitor (TPM) system will need to have the
sensors reset after a tire rotation is performed. A special
tool is needed to reset the sensor identification codes.
See your dealer for service. Make certain that all wheel
nuts are properly tightened. See ªWheel Nut Torqueº
in the Index.
CAUTION:
Rust or dirt on a wheel, or on the parts to which
it is fastened, can make wheel nuts become loose
after a time. The wheel could come off and cause
an accident. When you change a wheel, remove
any rust or dirt from places where the wheel
attaches to the vehicle. In an emergency,
you can use a cloth or a paper towel to do this;
but be sure to use a scraper or wire brush later,
if you need to, to get all the rust or dirt off.
See ªChanging a Flat Tireº in the Index.
