Programming Universal Home
Remote—Fixed Code
For questions or help programming
the Universal Home Remote
System, call 1-866-572-2728 or
go to www.learcar2u.com.
Most garage door openers sold
before 1996 are Fixed Code units.
Programming a garage door opener
involves time-sensitive actions, so
read the entire procedure before
starting. Otherwise, the device will
time out and the procedure will have
to be repeated.
To program up to three devices:
1. To verify that the garage door
opener is a Fixed Code unit,
remove the battery cover on the
hand-held transmitter supplied
by the manufacturer of the
garage door opener motor.
If there is a row of dip switches
similar to the graphic above,
the garage door opener is a
Fixed Code unit. If you do not
see a row of dip switches,
return to the previous section for
Programming Universal Home
Remote —Rolling Code. Your hand-held transmitter
can have between 8 to 12 dip
switches depending on the
brand of transmitter.
The garage door opener receiver
(motor head unit) could also
have a row of dip switches that
can be used when programming
the Universal Home Remote.
If the total number of switches
on the motor head and
hand-held transmitter are
different, or if the dip switch
settings are different, use the
dip switch settings on the
motor head unit to program
the Universal Home Remote.
The motor head dip switch
settings can also be used when
the original hand-held transmitter
is not available.

The exterior lamps control has four
positions:
O(Off):Turns off the automatic
headlamps and Daytime Running
Lamps (DRL). Turn the headlamp
control to the off position again to
turn the automatic headlamps or
DRL back on.
For vehicles first sold in Canada,
the off position will only work when
the vehicle is shifted into P (Park).
AUTO (Automatic): Automatically
turns on the headlamps at normal
brightness, together with the
following:
.Parking Lamps
.Instrument Panel Lights
.Taillamps
.License Plate Lamps
.Roof Marker Lamps
(If Equipped) When the vehicle is turned off and
the headlamps are in AUTO, the
headlamps may automatically
remain on for a set time. The time of
the delay can be changed using the
DIC. See
Driver Information Center
(DIC) on page 5‑32
;(Parking Lamps): Turns on
the parking lamps together with the
following:
.Instrument Panel Lights
.Taillamps
.License Plate Lamps
.Roof Marker Lamps
(If Equipped)
2(Headlamps): Turns on the

following:
.Parking Lamps
.Instrument Panel Lights
.Taillamps
.License Plate Lamps
.Roof Marker Lamps
(If Equipped)
When the headlamps are turned
on while the vehicle is on, the
headlamps turn off automatically
10 minutes after the ignition is
turned off. When the headlamps are
turned on while the vehicle is off,
the headlamps will stay on for
10 minutes before automatically
turning off to prevent the battery
from being drained. Turn the
headlamp control to off and then
back to the headlamp on position to
make the headlamps stay on for an
additional 10 minutes.
Push the turn signal/multifunction
lever toward the instrument panel to
change the headlamps from low
beam to high beam.

Reading Lamps
For vehicles with reading lamps,
they are located on the overhead
console.
To turn on the reading lamps, press
the button located next to each
lamp. To turn them off, press the
button again.
The vehicle may also have reading
lamps in other locations. To turn the
lamps on or off, press the button
located next to the lamp.
If the vehicle has a DVD Rear Seat
Entertainment (RSE) system, press
the lamp lenses to turn the lamps
on or off.
The lamps are fixed and cannot be
adjusted.
Lighting Features
Entry Lighting
The vehicle has an illuminated
entry feature.
When the doors are opened, the
dome lamps will come on if the
dome override button is in the
extended position. If the dome
override button is pressed in, the
lamps will not come on.
Exit Lighting
The interior lamps come on when
the key is removed from the ignition.
They turn off automatically in
20 seconds. The lights do not come
on if the dome override button is
pressed in.
Battery Load
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 bring the charge back up.
When the state of charge is high,
the voltage is lowered slightly to
prevent overcharging. If the vehicle
has a voltmeter gauge or a 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 of
the power needed for very high
electrical loads.
A high electrical load occurs when
several of the following are on,
such as: 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, a DIC message might
be displayed, such as BATTERY
SAVER ACTIVE, BATTERY
VOLTAGE LOW, or LOW BATTERY.
If one of these messages displays,
it is recommended that the driver
reduce the electrical loads as much
as possible. See
Driver Information
Center (DIC) on page 5‑32.Battery Power Protection
This feature shuts off the dome and
reading lamps, if they are left on for
more than 10 minutes after the
ignition is turned off. The cargo
lamp shuts off after 20 minutes.
This prevents the battery from
running down.

Infotainment System 7-15
XM™Satellite Radio Service
XM Satellite Radio Service gives
digital radio reception from coast to
coast in the 48 contiguous United
States, and in Canada. Just as
with FM, tall buildings or hills can
interfere with satellite radio signals,
causing the sound to fade in and
out. In addition, traveling or standing
under heavy foliage, bridges,
garages, or tunnels may cause loss
of the XM signal for a period of time.
Cellular Phone Usage
Cellular phone usage may cause
interference with the vehicle's radio.
This interference may occur when
making or receiving phone calls,
charging the phone's battery,
or simply having the phone on. This interference causes an
increased level of static while
listening to the radio. If static is
received while listening to the radio,
unplug the cellular phone and
turn it off.
Fixed Mast Antenna
The fixed mast antenna can
withstand most car washes without
being damaged as long as it is
securely attached to the base.
If the mast becomes slightly bent,
straighten it out by hand. If the mast
is badly bent, replace it.
Occasionally check to make sure
the antenna is tightened to its base.
If tightening is required, tighten
by hand until fully seated plus
one quarter turn.
Satellite Radio Antenna
The XM Satellite Radio antenna is
located on the roof of the vehicle.
Keep the antenna clear of
obstructions for clear radio
reception.
If the vehicle has a sunroof, the
performance of the XM system
(if equipped) may be affected if the
sunroof is open.

device, such as a portable audio
player. If a portable audio player is
not connected, “No Aux Input
Device” displays. If a disc is in both
the DVD slot and the CD slot,
the DVD/CD AUX button cycles
between the two sources and does
not indicate “No Aux Input Device.” If a front auxiliary device is
connected, the DVD/CD AUX
button cycles through all available
options, such as: DVD slot, CD slot,
front auxiliary, and rear auxiliary
(if available). See
