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 R/A. 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 to R/A
briey. Each time you do this, your vehicle will go
about 1 mph (1.6 km/h) faster.
Reducing Speed While Using
Cruise Control
There are two ways to reduce your speed while using
cruise control:
Press the button at the end of the lever until you
reach the lower speed you want, then release it.
To slow down in very small amounts, press the
button briey. 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 two ways to turn off the cruise control:
Step lightly on the brake pedal.
Move the cruise switch to OFF.
Erasing Speed Memory
When you turn off the cruise control or the ignition,
your cruise control set speed memory is erased.

Exterior Lamps
The exterior lamp control is located on the driver’s side
of the instrument panel.
The exterior lamp control has three positions:
9(Off):Turning the control to this position turns off
all lamps except the Daytime Running Lamps (DRL).
;(Parking Lamps):Turning the control to this
position turns on the parking lamps, together with
the following:
Sidemarker Lamps
Taillamps
License Plate Lamps
Instrument Panel Lights
Ashtray Lamp
O(Headlamps):Turning the control to this position
turns on the headlamps, together with the previously
listed lamps and lights.
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 dim.
Your vehicle is equipped with a light sensor on the
top of the instrument panel in the defroster grille.
Be sure it is not covered, or the system will be on
whenever the ignition is on.
The system may also turn on your headlamps when
driving through a parking garage, heavy overcast
weather or a tunnel. This is normal.
3-12

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.
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.
You may be able to turn off your automatic headlamp
system. See “Daytime Running Lamps (DRL)” later
in this section for more information.
As with any vehicle, you should turn on the regular
headlamps when you need them.
Lamps On Reminder
A reminder tone will sound when your headlamps or
parking lamps are manually turned on and your ignition
is in OFF, LOCK or ACCESSORY. To disable the
tone, turn the instrument panel brightness thumbwheel
all the way down. In the automatic mode, the
headlamps turn off once the ignition key is in OFF.
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 a reduced brightness when the following conditions
are met:
The ignition is on,
the exterior lamp control is off.
the automatic transmission is not in PARK (P),
the light sensor determines it is daytime and
the parking brake is released.
When the DRL are on, only your DRL lamps will be on.
The taillamps, sidemarker and other lamps won’t be
on. Your instrument panel won’t be lit up either.
When it begins to get dark, the automatic headlamp
system will switch from DRL to the headlamps or the last
chosen headlamp setting that was used.
3-13

To idle your vehicle with the DRL off, put the
transmission in PARK (P). The DRL will stay off
until you shift out of PARK (P).

reading and glove box lights if they are left on for more
than 20 minutes when the ignition is off. This will
keep your battery from running down.

to return to normal operation:
Shut off all lamps and close all doors, or
turn the ignition key to RUN.

Defogging and Defrosting
Turn the right knob to select the defog or defrost mode.
-(Blend):With this setting, the outside air comes
out of both the oor and defroster outlets. Adjust
the temperature knob for warmer or cooler air. The air
conditioning compressor may operate in this setting
to dehumidfy the air.
1(Defrost):This setting operates the defroster. Most
of the air comes out near the windshield, with some
going to the oor outlets and front side windows. The air
conditioning compressor may operate in this setting to
dehumidify the air.
The bi-level setting is useful for cold weather with a
large number of passengers or very humid conditions to
help keep the windshield clear. Use defrost to remove
fog or ice from the windshield quickly in extremely
cold conditions. The temperature knob should be in the
red area and the fan control toward high.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
The rear window defogger will only work when the
ignition is in RUN.
Press this button to turn
the rear window defogger
on or off. Be sure to
clear as much snow from
the window as possible.
The rear window defogger will turn off several minutes
after the button is pressed. If turned on again, the
defogger will run for several more minutes before turning
off. The defogger can also be turned off by pressing
the button again or by turning off the engine.

Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows AIR BAG or the air bag symbol.
The system checks the air bag’s electrical system
for malfunctions. The light tells you if there is an
electrical problem. The system check includes the air
bag sensor, the air bag modules, the wiring and
the crash sensing and diagnostic module. For more
information on the air bag system, seeAir Bag System
on page 1-62.
This light will come on when you start your vehicle,
and it will ash for a few seconds. Then the light should
go out. This means the system is ready.If the air bag readiness light stays on after you start the
vehicle or comes on when you are driving, your air
bag system may not work properly. Have your vehicle
serviced right away.
{CAUTION:
If the air bag readiness light stays on after you
start your vehicle, it means the air bag system
may not be working properly. The air bags in
your vehicle may not inate in a crash, or they
could even inate without a crash. To help avoid
injury to yourself or others, have your vehicle
serviced right away if the air bag readiness light
stays on after you start your vehicle.
The air bag readiness light should ash for a few
seconds when you turn the ignition key to RUN. If the
light doesn’t come on then, have it xed so it will
be ready to warn you if there is a problem. United States
