6. Locate in the garage, the garage door opener
receiver (motor-head unit). Locate the ªLearnº
or ªSmartº button. This can usually be found where
the hanging antenna wire is attached to the
motor-head unit.
7. Firmly press and release the ªLearnº or ªSmartº
button. The name and color of the button may
vary by manufacturer.
You will have 30 seconds to start Step 8.
8. Return to the vehicle. Firmly press and hold the
programmed HomeLink
žbutton for two seconds,
then release. Repeat the press/hold/release
sequence a second time, and depending on the
brand of the garage door opener (or other rolling
code device), repeat this sequence a third time
to complete the programming.
HomeLink
žshould now activate your rolling-code
equipped device.
To program the remaining two HomeLink
žbuttons,
begin with Step 2 of ªProgramming HomeLinkž.º Do not
repeat Step 1.
Gate Operator and Canadian
Programming
Canadian radio-frequency laws require transmitter
signals to ªtime outº or quit after several seconds of
transmission. This may not be long enough for
HomeLink
žto pick up the signal during programming.
Similarly, some U.S. gate operators are manufactured to
ªtime outº in the same manner.
If you live in Canada, or you are having difficulty
programming a gate operator by using the
ªProgramming HomeLink
žº procedures (regardless of
where you live), replace Step 3 under ªProgramming
HomeLink
žº with the following:
Continue to press and hold the HomeLink
žbutton while
you press and release every two seconds (cycle)
your hand-held transmitter until the frequency signal has
been successfully accepted by HomeLink
ž. The
indicator light will ¯ash slowly at ®rst and then rapidly.
Proceed with Step 4 under ªProgramming HomeLink
žº
to complete.
2-49

Using HomeLinkž
Press and hold the appropriate HomeLinkžbutton for at
least half of a second. The indicator light will come
on while the signal is being transmitted.
Erasing HomeLinkžButtons
To erase programming from the three buttons do the
following:
1. Press and hold down the two outside buttons until
the indicator light begins to ¯ash, after 20 seconds.
2. Release both buttons. Do not hold for longer than
30 seconds.
HomeLink
žis now in the train (learning) mode and can
be programmed at any time beginning with Step 2
under ªProgramming HomeLink
ž.º
Individual buttons can not be erased, but they can be
reprogrammed. See ªReprogramming a Single
HomeLink

To program a device to HomeLinkžusing a HomeLinkž
button previously trained, follow these steps:
1. Press and hold the desired HomeLink
žbutton.
Do not release the button.
2. The indicator light will begin to ¯ash after
20 seconds. While still holding the HomeLink
ž
button, proceed with Step 2 under ªProgramming
HomeLinkž.º
Resetting Defaults
To reset HomeLinkžto default settings do the following:
1. Hold down the two outside buttons for about
20 seconds until the indicator light begins to ¯ash.
2. Continue to hold both buttons until the HomeLink

Headlamp High/Low-Beam Changer
To change the headlamps from low to high beam, push
the lever toward the instrument panel. To return to
low-beam headlamps, pull the multifunction lever toward
you. Then release it.
When the high beams are
on, this indicator light on
the instrument panel
cluster will also be on.
Flash-to-Pass
This feature lets you use your high-beam headlamps to
signal a driver in front of you that you want to pass.
It works even if your headlamps are in the automatic
position.
To use it, pull the turn signal lever toward you, then
release it.
If your headlamps are in the automatic position or on
low beam, your high-beam headlamps will turn on.
They'll stay on as long as you hold the lever toward you.
The high-beam indicator on the instrument panel
cluster will come on. Release the lever to return to
normal operation.
Windshield Wipers
8
(Mist):For a single wiping cycle, turn the band to
mist. Hold it there until the wipers start. Then let go.
The wipers will stop after one wipe. If you want
more wipes, hold the band on mist longer.
9(Off):To stop the wipers, move the band to off.
N(Windshield Wipers):Turn the band to control the
windshield wipers.
You can set the wiper speed for a long or short delay
between wipes. This can be very useful in light rain
or snow. Turn the band to choose the delay time. The
closer to the top of the lever, the shorter the delay.
For steady wiping at low speed, turn the band away from
you to the ®rst solid band past the delay settings. For
high-speed wiping, turn the band further, to the second
solid band past the delay settings. To stop the wipers,
move the band to off.
Be sure to clear ice and snow from the wiper blades
before using them. If they're frozen to the windshield,
carefully loosen or thaw them. If your blades do become
worn or damaged, get new blades or blade inserts.

Setting Cruise Control
1. Move the cruise control switch to on.
2. Get up to the speed you want.
3. Press the set button at the end of the lever and
release it.
4. Take your foot off the accelerator pedal.
The accelerator pedal will not go down.
The cruise light on the
instrument panel cluster
will come on when
the cruise control is
engaged.
Resuming a Set Speed
Suppose you set your cruise control at a desired speed
and then you apply the brake. This, of course, shuts
off the cruise control. But you don't need to reset it.Once you're going about 25 mph (40 km/h) or more, you
can move the cruise control switch brie¯y from on to
resume/accelerate.
You'll go right back up to your chosen speed and stay
there.
If you hold the switch at resume/accelerate, the vehicle
will keep going faster until you release the switch or
apply the brake. So unless you want to go faster, don't
hold the switch at resume/accelerate.
Increasing Speed While Using Cruise
Control
There are two ways to go to a higher speed:
·Use the accelerator pedal to get to the higher
speed. Press the button at the end of the lever, then
release the button and the accelerator pedal.
You'll now cruise at the higher speed.
·Move the cruise switch from on to
resume/accelerate. Hold it there until you get up to
the speed you want, and then release the switch.
To increase your speed in very small amounts,
move the switch brie¯y to resume/accelerate. Each
time you do this, your vehicle will go about
1 mph (1.6 km/h) faster.
3-12

Reducing Speed While Using Cruise
Control
Press the set button at the end of the lever until you
reach the lower speed you want, then release it. Each
time you do this, you'll go about 1 mph (1.6 km/h)
slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase your speed.
When you take your foot off the pedal, your vehicle will
slow down to the cruise control speed you set earlier.
Using Cruise Control on Hills
How well your cruise control will work on hills depends
upon your speed, load and the steepness of the
hills. When going up steep hills, you may want to step
on the accelerator pedal to maintain your speed.
When going downhill, you may have to brake or shift to
a lower gear to keep your speed down. Of course,
applying the brake takes you out of cruise control. Many
drivers ®nd this to be too much trouble and don't use
cruise control on steep hills.
Ending Cruise Control
There are three ways to turn off the cruise control:
·Step lightly on the brake pedal.
·Move the cruise switch to off, or
·Shift the transmission to NEUTRAL (N).
Erasing Speed Memory
When you turn off the cruise control or the ignition, your
cruise control set speed memory is erased.
3-13

Exterior Lamps
Your exterior lamps knob
is located on your
instrument panel to the left
of the steering wheel.
c(Off):Turn the knob to this symbol and release it to
turn off the Daytime Running Lamps (DRL) and the
automatic headlamps. An indicator will illuminate when
the position is selected. This position is not available
for vehicles ®rst sold in Canada.
i(Automatic DRL/AHS):Turning the knob to this
symbol puts the system into automatic headlamp mode.
An indicator will illuminate when the position is
selected.
;(Parking Lamps):Turn the knob to this symbol to
manually turn on the following:
·Parking Lamps
·Sidemarker Lamps
·Taillamps
·License Plate Lamps
·Instrument Panel Lights
2(Headlamps):Turn the knob to this symbol to turn
on all the lamps listed as well as the headlamps.
Automatic Headlamp System
When it is dark enough outside, your Automatic
Headlamp System will turn on your headlamps at the
normal brightness along with other lamps such as
the taillamps, sidemarker, parking lamps and the
instrument panel lights. The radio lights will also be on.
Your vehicle is equipped with a light sensor on the
top of the instrument panel. Be sure it is not covered or
the system will be on whenever the ignition is on.
The system may also turn on your lights when driving
through a parking garage, heavy overcast weather
or a tunnel. This is normal.
3-14

There is a delay in the transition between the daytime
and nighttime operation of the Daytime Running
Lamps (DRL) and the automatic headlamp systems, so
that driving under bridges or bright overhead street
lights does not affect the system. The DRL and
automatic headlamp system will only be affected when
the light sensor sees a change in lighting lasting
longer than the delay.
If you start your vehicle in a dark garage, the automatic
headlamp system will come on immediately. Once
you leave the garage, it will take about one minute for
the automatic headlamp system to change to DRL if it is
light outside. During that delay, your instrument panel
cluster may not be as bright as usual. Make sure
your instrument panel brightness control is in the full
bright position.
To idle your vehicle with the automatic headlamp
system off, set the parking brake while the ignition is off.
Then start your vehicle. The automatic headlamp
system will stay off until you release the parking brake,
shift out of park or turn the exterior lamp control to
the off position as described in ªExterior Lampsº listed
previously.
Lamps On Reminder
A reminder tone will sound when your headlamps or
parking lamps are manually turned on, the driver's door
is open and your ignition is in LOCK or ACCESSORY.To turn the tone off, turn the knob all the way
counterclockwise. In the automatic mode, the headlamps
turn off once the ignition key is in LOCK.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the
day. DRL can be helpful in many different driving
conditions, but they can be especially helpful in the short
periods after dawn and before sunset. Fully functional
daytime running lamps are required on all vehicles
®rst sold in Canada.
The DRL system will make your headlamps come
on at reduced brightness when the following conditions
are met:
·The ignition is on
·the exterior lamps knob is in automatic
headlamp mode
·the light sensor detects daytime light
·the transmission is not in PARK (P)
When the DRL are on, only your headlamps will be on.
The taillamps, sidemarker and other lamps won't be
on. The instrument panel won't be lit up either.
When it begins to get dark, the headlamps will
automatically switch from DRL to the regular headlamps.
3-15

Fog Lamps
Your vehicle may have this feature. Use your fog lamps
for better vision in foggy or misty conditions. Your
ignition must be in RUN for your fog lamps to work.
The fog lamp button is
located on the instrument
panel to the right of
the exterior lamps knob.
Press the button to turn the fog lamps on. Press the
button again to turn them off. A light will glow near the
button while the fog lamps are on. Fog lamps will
turn off whenever your high-beam headlamps are on.
Interior Lamps
Instrument Panel Brightness
Press the knob located
next to the exterior lamps
knob to extend it.
Turn the knob to adjust the instrument panel lights. Turn
the knob all the way up to turn on the interior lamps.
Press the knob back into its stored position when you're
not using it.
