Cruise Control
With cruise control, you can maintain a speed of about
25 mph (40 km/h) or more without keeping your foot
on the accelerator. This can really help on long
trips. Cruise control does not work at speeds below
about 25 mph (40 km/h).
When you apply your brakes, the cruise control
shuts off.
{CAUTION:
Cruise control can be dangerous where you
can not drive safely at a steady speed. So, do
not use your cruise control on winding roads
or in heavy traffic.
Cruise control can be dangerous on slippery
roads. On such roads, fast changes in tire
traction can cause needless wheel spinning,
and you could lose control. Do not use cruise
control on slippery roads.If your vehicle is in cruise control when the traction
control system (option) begins to limit wheel spin, the
cruise control will automatically disengage. SeeTraction
Control System (TCS) (3800 V6 Engine) on page 4-8.
When road conditions allow you to safely use it
again, you may turn the cruise control back on.
Setting Cruise Control
The cruise control ON/OFF switch is located at the end
of the multifunction lever.
{CAUTION:
If you leave your cruise control on when you
are not using cruise, you might hit a button
and go into cruise when you do not want to.
You could be startled and even lose control.
Keep the cruise control switch off until you
want to use cruise control.
1. Slide the cruise control ON lever, on the turn signal
lever, to the right to turn it on.
2. Get up to the speed you want.

?(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 help heat or
cool the air inside your vehicle more quickly. Press this
button to turn the recirculation mode on. When the button
is pressed, an indicator light will come on.
You may have to set the instrument panel brightness
control to the highest setting during the day to see the
indicator lamp.
The recirculation mode cannot be used with outside
air modes.
D or P (Temperature Control):Slide the levers
marked D (Driver) or P (Passenger) to increase or
decrease the temperature on the driver’s side or
the passenger’s side of the vehicle.
#(Air Conditioning):Press this button to turn the
air conditioning system on or off. When A/C is pressed,
an indicator light will come on to let you know that
the air conditioning has been activated.
You may have to set the instrument panel brightness
control to the highest setting during the day to see
the indicator lamp.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, do the following:
1. Select the vent mode.
2. Select the recirculation mode.
3. Select A/C.
4. Select the coolest temperature for both zones.
5. Select the highest fan speeds.
Using these settings together for long periods of time
may cause the air inside of your vehicle to become
too dry. To prevent this from happening, after the
air inside of 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.

Defogging and Defrosting
Fog on the inside of the 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 or frost from your windshield. Use the defog
mode to clear the windows of fog or moisture and warm
the passengers. Use the defrost mode to remove fog
or frost from the windshield more quickly.
Turn the right knob clockwise to select the defog or
defrost mode.
-(Defog):This mode directs air equally to 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 below 40°F (4°C). The recirculation mode cannot
be selected while in the defog mode.
Do not drive the vehicle until all the windows are clear.
0(Defrost):This mode directs half of the air to the
windshield and side window vents and half to the oor
vents. In this mode, the system will automatically force
outside air into your vehicle. The recirculation mode
cannot be selected while in the defog mode. The air
conditioning compressor will run automatically in this
setting, unless the outside temperature is below
40°F (4°C).
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 from the rear window.
<:The rear window defogger will turn off
approximately 20 minutes after the button is pressed.
If turned on again, the defogger will run for the
same amount of time. The defogger can also be turned
off by pressing the button again or by turning off the
engine.
Do not drive the vehicle until all the windows are clear.
If your vehicle has heated outside rearview mirrors,
the mirrors will heat to help clear fog or frost from the
surface of the mirror when the rear window defog button
is pressed.
Notice:Don’t use anything sharp on the inside of
the rear window. If you do, you could cut or damage
the warming grid, and the repairs wouldn’t be
covered by your warranty. Do not attach a temporary
vehicle license, tape, a decal or anything similar
to the defogger grid.

Passenger Compartment Air Filter
Your vehicle may be equipped with a passenger
compartment particulate air lter. It is located
underneath the hood just below the windshield wiper
arm on the passenger’s side of the vehicle, underneath
the air inlet grille.
The lter traps most of the pollen from air entering the
Climate Control System. Like your engine’s air
cleaner/lter, it may need to be changed periodically to
insure system performance. For information on how
often to change the passenger compartment air
lter, seeScheduled Maintenance on page 6-4.
To change the passenger compartment air lter, use the
following steps:
1. Turn off the ignition when the windshield wipers are
in the up position.
2. Raise the vehicle hood.
3. Disconnect the windshield washer pump hose from
the fender rail and air inlet grille.
4. Peel back the hood weatherstrip from the
passenger’s side of the vehicle halfway to center.5. Remove the air inlet grille retainers.
6. Remove the air inlet grille.
7. Remove the air deector grille in the compartment.
8. Remove the old passenger compartment air
lter.
9. Reverse the steps to install the new air lter.
For the type of lter to use, seeNormal Maintenance
Replacement Parts on page 6-13.

Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that something
is wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention
to your warning lights and gages could also save
you or others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions. As you
will see in the details on the next few pages, some
warning lights come on briey when you start the engine
just to let you know they’re working. If you are familiar
with this section, you should not be alarmed when
this happens.Gages can indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages
and warning lights work together to let you know when
there’s a problem with your vehicle.
When one of the warning lights comes on and stays
on when you are driving, or when one of the gages
shows there may be a problem, check the section that
tells you what to do about it. Please follow this
manual’s advice. Waiting to do repairs can be
costly – and even dangerous. So please get to know
your warning lights and gages. They’re a big help.
Your vehicle may also have a Driver Information
Center (DIC) that works along with the warning lights
and gages. SeeDriver Information Center (DIC)
on page 3-52.

Instrument Panel Cluster
Your instrument panel cluster is designed to let you know at a glance how your vehicle is running. You’ll know how
fast you’re going, about how much fuel is in your tank and many other things you need to drive safely and
economically.

Your vehicle may have a
tachometer that displays
the engine speed in
thousands of revolutions
per minute (rpm).
Notice:If you operate the engine with the
tachometer in the shaded warning area, your vehicle
could be damaged, and the damages would not
be covered by your warranty. Do not operate
the engine with the tachometer in the shaded
warning area.
Safety Belt Reminder Light
When the key is turned to ON, a chime will come on for
about several seconds to remind people to fasten
their safety belts, unless the driver’s safety belt is
already buckled.
The safety belt light will
also come on and stay on
for several seconds, then it
will ash for several more.
