Universal Home Remote System
Operation (With One Triangular LED)
Your vehicle may have the Universal Home
Remote System. If there is one triangular Light
Emitting Diode (LED) above the Universal
Home Remote buttons, follow the instructions
below. If your vehicle has three round LED above
the Universal Home Remote buttons, follow the
instructions under Universal Home Remote System
Operation (With three round LED).
Do not use the Universal Home Remote with any
garage door opener that does not have the stop
and reverse feature. This includes any garage door
opener model manufactured before April 1, 1982.
If you have a newer garage door opener with rolling
codes, please be sure to follow Steps 6 through 8 to
complete the programming of your Universal Home
Remote Transmitter.Read the instructions completely before attempting
to program the Universal Home Remote.
Because of the steps involved, it may be helpful to
have another person available to assist you in
the programming steps.
Keep the original hand-held transmitter for use in
other vehicles as well as for future Universal
Home Remote programming. It is also
recommended that upon the sale of the vehicle,
the programmed Universal Home Remote buttons
should be erased for security purposes. See
“Erasing Universal Home Remote Buttons” later in
this section or, for assistance, seeCustomer
Assistance Offices on page 482.
Be sure that people and objects are clear of the
garage door or gate operator you are
programming. When programming a garage door,
it is advised to park outside of the garage.
It is recommended that a new battery be installed
in your hand-held transmitter for quicker and
more accurate transmission of the radio-frequency
signal.

When it is dark enough outside, the DRL will turn
off and the vehicle’s headlamps and parking
lamps will turn on. The other lamps that come on
with the headlamps will also come on.
When it is bright enough outside, the headlamps
will go off and the DRL will come on.
To idle the vehicle with the DRL off, turn the
exterior lamp control off and then do one of the
following:
Turn the exterior lamp control to the parking
lamp position.
Turn the exterior lamp control to the
headlamp position.
Turn the exterior lamp control from AUTO to
off and back to AUTO.
This feature is not available for vehicles rst sold
in Canada.
To turn off the automatic headlamp feature when it
is dark outside, move the exterior lamp control
to the parking lamp position. The parking lamps
remain on and the headlamps turn off. The
fog lamps also go on if they were on previously.
As with any vehicle, the regular headlamp system
should be turned on when needed.
Fog Lamps
If your vehicle has fog
lamps, the button is
located in the center of
the exterior lamps
control on the left side
of the steering column.
Press the fog lamps button to turn the lamps
on or off.
While the high-beam headlamps are on, the fog
lamps are off.
Some localities have laws that require the
headlamps to be on along with the fog lamps.
Exterior Lighting Battery Saver
If the parking lamps or headlamps have been left
on after the ignition has been turned to off, the
exterior lamps will turn off after about 10 minutes.
This protects the battery from being drained.
Use the exterior lamp control to turn the lamps
back on, if they are still needed.
160

Perimeter Lighting
Perimeter lighting provides a period of exterior
vehicle lighting. Perimeter lighting activates when
the key is removed from the ignition or the vehicle is
unlocked using the Remote Keyless Entry (RKE)
transmitter. The amount of time the exterior lamps
will remain on can be programmed using the Driver
Information Center (DIC). See “EXIT LIGHT
DELAY” underDIC Vehicle Personalization on
page 229for additional information.
Overhead Console Reading Lamps
Your vehicle may have reading lamps located
on the overhead console. Press the lens to turn
them on and off.
Rear Assist Handle Reading Lamps
Your vehicle may have reading lamps located
near the rear assist handles. Press the lens to turn
them on and off.
Electric Power Management
The vehicle has Electric Power Management (EPM)
that estimates the battery’s temperature and state
of charge. It then adjusts the voltage for best
performance and extended life of the battery.
When the battery’s state of charge is low, the
voltage is raised slightly to quickly put the charge
back in. When the state of charge is high, the
voltage is lowered slightly to prevent overcharging.
If the vehicle has a voltmeter gage or voltage
display on the Driver Information Center (DIC), you
may see the voltage move up or down. This is
normal. If there is a problem, an alert will be
displayed.
The battery can be discharged at idle if the
electrical loads are very high. This is true for all
vehicles. This is because the generator (alternator)
may not be spinning fast enough at idle to
produce all the power that is needed for very high
electrical loads.
163

A high electrical load occurs when several of the
following loads are on: headlamps, high beams,
fog lamps, rear window defogger, climate
control fan at high speed, heated seats, engine
cooling fans, trailer loads, and loads plugged into
accessory power outlets.
EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s
output and the vehicle’s electrical needs. It
can increase engine idle speed to generate more
power, whenever needed. It can temporarily
reduce the power demands of some accessories.
Normally, these actions occur in steps or levels,
without being noticeable. In rare cases at the
highest levels of corrective action, this action may
be noticeable to the driver. If so, the Driver
Information Center (DIC) message might display
Battery Saver Active. If this message is displayed,
it is recommended that the driver reduce the
electrical loads as much as possible. See
DIC Warnings and Messages on page 208.Battery Run-Down Protection
This helps prevent the vehicle’s battery from
draining in case the interior courtesy lamps,
reading lamps, trunk lamp, underhood lamp, glove
box lamps, or sun visor vanity lamps, if equipped,
are accidently left on. If any of these lamps
are left on while the ignition is off, they will
automatically turn off after 10 minutes. The lamps
will not come back on again until one of the
following occurs:
The ignition is turned on.
The interior lamps control is turned off, then to
door or on.
Ultrasonic Rear Parking
Assist (URPA)
Your vehicle may be equipped with Ultrasonic Rear
Parking Assist (URPA). URPA is designed to help
you park while in REVERSE (R) and operates only
at speeds less than 3 mph (5 km/h). URPA can help
you avoid colliding with objects such as parked
vehicles. The system can detect objects 5 feet
(1.5 m) behind your vehicle and tell you how close
those objects are to your rear bumper.
164

Accessory Power Outlet(s)
The accessory power outlets enable power
electrical equipment such as a cellular telephone
or a CB radio to be used inside the vehicle.
Your vehicle has 12-volt outlets. One outlet is
located on the center console below the climate
controls. There may be another outlet located
inside the center storage console or in the ip and
fold console.
Open the cover to use the outlet. Be sure to close
the cover when the outlet is not in use.
Notice:Adding any electrical equipment to
your vehicle may damage it or keep other
components from working as they should. The
repairs would not be covered by your warranty.
Do not use equipment exceeding maximum
amperage rating of 20 amperes. Check with
your dealer before adding electrical equipment.Certain power accessory plugs may not be
compatible to the power accessory outlet and
could result in blown vehicle or adapter fuses.
If you experience a problem, see your dealer.
Notice:Improper use of the power outlet can
cause damage not covered by your warranty.
Do not hang any type of accessory or
accessory bracket from the plug because the
power outlets are designed for accessory
power plugs only.
Notice:Leaving electrical equipment plugged
in for an extended period of time while the
vehicle is off will drain the battery. Power is
always supplied to the outlets. Always unplug
electrical equipment when not in use and
do not plug in equipment that exceeds
the maximum 20 ampere rating.
When adding electrical equipment, be sure to
follow the proper installation instructions included
with the equipment.
167

SeePassenger Sensing System on page 75for
more on this, including important safety
information.
If, after several seconds, all status indicator lights
remain on, or if there are no lights at all, there
may be a problem with the lights or the passenger
sensing system. See your dealer for service.
{CAUTION:
If the off indicator and the airbag
readiness light ever come on together, it
means that something may be wrong with
the airbag system. If this ever happens,
have the vehicle serviced promptly,
because an adult-size person sitting in the
right front passenger seat may not have
the protection of the frontal airbag. See
Airbag Readiness Light on page 182.
Charging System Light
This light comes on
briey when the ignition
is turned on, as a
check to show that it is
working. Then it
should go out.
If it stays on, or comes on while the vehicle is being
driven, a chime will sound and there may be a
problem with the charging system. It could indicate
that the vehicle has a loose accessory belt or
another electrical problem. Have it checked right
away. Driving while this light is on could drain the
battery and result in the engine suddenly stopping.
If the vehicle must be driven a short distance with
the light on, be certain to turn off all unnecessary
electrical loads, such as the radio, heater fan,
air conditioning fan, and heated seats.
185

Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel.
SeeGasoline Octane on page 343. Poor fuel
quality will cause your engine not to run as
efficiently as designed. You may notice this as
stalling after start-up, stalling when you put
the vehicle into gear, misring, hesitation on
acceleration, or stumbling on acceleration. (These
conditions may go away once the engine is
warmed up.) This will be detected by the system
and cause the light to turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at
least one full tank of the proper fuel to turn the
light off.
If none of the above steps have made the light
turn off, your dealer can check the vehicle.
Your dealer has the proper test equipment and
diagnostic tools to x any mechanical or electrical
problems that may have developed.Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have
or may begin programs to inspect the emission
control equipment on your vehicle. Failure to pass
this inspection could prevent you from getting a
vehicle registration.
Here are some things you need to know to help
your vehicle pass an inspection:
Your vehicle will not pass this inspection if the
check engine light is on or not working properly.
Your vehicle will not pass this inspection if
the OBD (on-board diagnostic) system determines
that critical emission control systems have not
been completely diagnosed by the system.
The vehicle would be considered not ready for
inspection. This can happen if you have recently
replaced your battery or if your battery has
run down. The diagnostic system is designed to
evaluate critical emission control systems
during normal driving. This may take several days
of routine driving. If you have done this and
your vehicle still does not pass the inspection for
lack of OBD system readiness, your dealer
can prepare the vehicle for inspection.
193

The DIC on the uplevel vehicle also allows some
features to be customized or personalized.
SeeDIC Vehicle Personalization on page 229for
more information.
DIC Operation and Displays
The DIC has different modes which can be
accessed by pressing the DIC buttons located on
the center of the instrument panel. Depending
on whether your vehicle has the base level
or uplevel DIC, the buttons and modes available
will differ.
The buttons on the base level vehicle are the
trip/odometer and English/Metric buttons.
The buttons on the uplevel vehicle are the trip/
odometer, fuel, gages, set/reset, and option
buttons.
The button functions are detailed in the
following pages.
DIC Buttons
TRIP/ODO (Trip/Odometer):Press this button on
the base level vehicle to display the odometer
and trip distance.
Press this button on the uplevel vehicle to display
the odometer, trip distance, time elapsed, and

Fuel Menu Items (Uplevel Only)
.
(Fuel):Press this button to scroll through the
following menu items:
Fuel Range
Press the fuel button until FUEL RANGE displays.
This mode shows the approximate number of
remaining miles or kilometers the vehicle can be
driven without refueling.
Fuel range is based on several factors, including
distance traveled, fuel used, fuel capacity, etc.
This estimate will change if driving conditions
change. For example, if driving in traffic and
making frequent stops, this mode may read
one number, but if the vehicle is driven on a
freeway, the number may change even though the
same amount of fuel is in the fuel tank. This is
because different driving conditions produce
different fuel economies. Generally, freeway
driving produces better fuel economy than city
driving. Fuel range cannot be reset.
If your vehicle is low on fuel, FUEL RANGE LOW
will display followed by the LOW FUEL message.
See “LOW FUEL” underDIC Warnings and
Messages on page 208for more information.
Average Fuel Economy
Press the fuel button until AVG ECONOMY
displays. This mode shows the approximate
average miles per gallon (mpg) or liters per
100 kilometers (L/100 km). This number is
calculated based on the number of mpg (L/100 km)
recorded since the last time this menu item was
reset. To reset AVG ECONOMY, press and hold
the set/reset button. The display will return to zero.
Gages Menu Items (Uplevel Only)
