2-37 Flash-To-Pass
This feature lets you use the high-beam headlamps to
signal the driver in front of you that you want to pass.
Pull the turn signal lever toward you briefly to
flash
-to-pass. When you do:

If the headlamps are either off or in the Daytime
Running Lamps (DRL) mode, the high
-beam
headlamps will turn on. They'll stay on as long as
you hold the lever there. Release the lever to turn
them off.

If the headlamps are on low beam, they will remain
active and the high beam will also illuminate until
you release the lever.
Windshield Wipers
You can control the windshield wipers by moving the
lever with the wiper symbol on it. This lever is located
on the right side of your steering column. For
information on wiper
-activated headlamp operation,
refer to ªWiper
-Activated Headlampsº in the Index.
LO or HI: Move the lever up to LO for steady wiping
at a slow speed. Move the lever higher to HI for steady
wiping at a high speed.

INT (DELAY): Move the lever up to the INT position,
then turn the INT ADJ band, which is located on the
lever, to adjust the delay time. The higher you turn the
INT ADJ band, the more frequent the wipers
will operate.
OFF: Lower the lever to its resting position (OFF) to
turn off the wipers.
MIST: Pull the lever down once and release it for a
single wipe cycle. For more cycles, hold the lever down
in the MIST position longer.
To wash the windshield, press the button located at the
tip of the lever.
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 the blades do become
damaged, get new blades or blade inserts.
Heavy snow or ice can overload the wiper motor. A
circuit breaker will stop the motor until it cools. Clear
away snow or ice to prevent an overload.Rainsense
Wipers (If Equipped)
The moisture sensor is mounted on the passenger's
interior side of the windshield behind the rearview
mirror and is used to automatically operate the wipers
by monitoring the amount of moisture that is on
the windshield.
The Rainsense system can be activated by moving the
wiper stalk up to the INT position and turning the INT
ADJ band to one of five sensitivity settings. The bottom
INT ADJ position is the lowest sensitivity setting. This
allows more water to collect on the windshield between
wipes. Turning the INT ADJ band to the other INT ADJ
settings increases the sensitivity of the system and the
frequency of wipes. A single wipe will occur each time
you turn the INT ADJ band to a higher sensitivity
setting. An initial wipe occurs when you turn the
ignition on as a reminder that Rainsense is active. The
windshield wipers also remain in a ªhigh parkº position,
even when the ignition is turned off.
The Rainsense wipers operate in a delay mode as well as
a continuous low or high speed depending on the
amount of moisture and the sensitivity setting. The
MIST and ªwashº cycles operate as normal and are not
affected by the Rainsense function.

2-39
NOTICE:
The wipers must be turned off when going
through a car wash to avoid damage.
It is important to note that the Rainsense wiping feature
(INT ADJ) can be overridden at any time by manually
changing the wiper control to LO or HI speed.
NOTICE:
Do not place stickers or other items on the
exterior glass surface directly in front of the
moisture sensor. Doing this could cause the
moisture sensor to malfunction.
Windshield Washer
The windshield washer has both a ªdemandº mode and a
ªprogrammedº mode, depending on the amount of
windshield washer fluid you need.
CAUTION:
In freezing weather, don't use your washer until
the windshield is warmed. Otherwise the washer
fluid can form ice on the windshield, blocking
your vision.
To spray washer fluid on the windshield in the
programmed mode, press and release the button on the
tip of the lever. The washer will provide a measured
amount of fluid to the windshield and the wiper will
either stop or return to your original wiping speed. To
spray washer fluid on the windshield in the demand
mode, press and hold the button until you have enough
fluid, and the wipers will either stop or return to your
original wiping speed.
CHECK WASHER FLUID will be displayed on the DIC
when the washer fluid reaches a low level.

2-40 Cruise Control
The cruise control lever is
located on the lower right
side of the steering column.
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 help on long trips. Cruise
control does not work at speeds below about 25 mph
(40 km/h). When cruise control is on, you will see a
telltale labeled CRUISE in the instrument cluster.
Cruise control shuts off when you apply your brakes.CAUTION:

Cruise control can be dangerous where you
can't drive safely at a steady speed. So,
don't 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. Don't
use cruise control on slippery roads.
If your vehicle is in cruise control when the traction
control system begins to limit wheel spin, the cruise
control will automatically disengage. (See ªTraction
Control Systemº in the Index.) When road conditions
allow you to safely use it again, you may turn the cruise
control back on.

Setting Cruise Control
CAUTION:
If you leave your cruise control switch on when
you're not using cruise, you might hit a button
and go into cruise when you don't want to. You
could be startled and even lose control. Keep the
cruise control switch off until you want to use it.
1. Press the button at the end of the lever to turn on
the system.
2. Accelerate to the speed you want.
3. Move the lever down once to SET/CST. The
CRUISE telltale will come on.
4. Remove your foot from the accelerator pedal.
Resuming a Set Speed
Setting the cruise control at a desired speed and then
applying the brake will end the cruise function.Once you're going about 25 mph (40 km/h) or more,
you can move the cruise control lever up to RES/ACC
(Resume/Accelerate) briefly to reset. This returns you to
your desired preset speed. The CRUISE telltale will
come on.
If you hold the lever at RES/ACC more than half a
second, the vehicle will accelerate until you release the
lever or apply the brake. So unless you want to go faster,
don't hold the lever at RES/ACC.
Increasing Speed While Using Cruise Control
There are two ways to go to a higher speed:

Use the accelerator pedal to go to a higher speed.
Move the cruise lever to SET/CST and then release
the lever and the accelerator pedal. You'll now cruise
at the higher speed.

Move the lever up to RES/ACC. Hold it there until
you reach a desired speed and then release the lever.
To increase your speed in very small amounts, move
the lever up to RES/ACC one second at a time. Each
time you do this, your vehicle will go about 1 mph
(1.6 km/h) faster.
The accelerate feature will only work after you have set
the cruise control speed by moving the cruise lever
down to SET/CST.

2-42
Reducing Speed While Using Cruise Control
There are two ways to reduce your speed while using
cruise control:

Move the cruise lever down to SET/CST and hold it
there until you reach a desired lower speed, then
release it.

To slow down in very small amounts, move the
cruise lever to SET/CST briefly. Each time you do
this, you'll go 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 have 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 brakes
or downshifting into FIRST (1) takes you out of cruise
control. Many drivers find this to be too much trouble
and don't use cruise control on steep hills.
Ending Cruise Control
There are three ways to end cruise control:

Step lightly on the brake pedal.

Press the button at the end of the cruise lever.

Pull the cruise lever (CANCEL) toward you.
Erasing Speed Memory
The cruise control set speed memory is erased when you
turn off the cruise control or the ignition.

Exterior Lamps
The control on the left
side of the instrument
panel controls these
lamp systems:

Parking Lamps

Headlamps

Taillamps

Sidemarker Lamps

License Plate Lamp

Underhood Lamp

Fog Lamps (STS Only)

Instrument Panel Lights

Interior Courtesy Lamps
Instrument panel backlighting will dim only when it is
dark outside.
Parking Lamps
Turn the exterior lamps control knob once clockwise to
turn on the parking lamps, taillamps, sidemarker lamps,
license plate lamp and underhood lamp. Turn the control
counterclockwise to turn these lamps off. The parking
brake indicator light will be on if the parking lamps
are on.
Headlamps
The control for the headlamps is on the left side of the
instrument panel. Turn the exterior lamps control knob
all the way clockwise to turn the headlamps on. Turn the
control knob all the way counterclockwise to turn the
headlamps off.
Wiper
-Activated Headlamps
This feature turns on the headlamps and parking lamps
after the windshield wipers have been in use for
approximately six seconds.
To operate the wiper
-activated headlamps, the Twilight
Sentinel must be on. If the wiper-activated headlamps
are on and the ignition key is turned to ACC, the
wiper
-activated headlamps will continue. When you
turn the key to OFF or ACC, the wiper
-activated
headlamps will immediately turn off.

yellowblue
2-44
The wiper-activated headlamps will turn off if you turn
off the Twilight Sentinel or the windshield wipers. If
turned off by deactivating the Twilight Sentinel, a
HEADLAMPS SUGGESTED message will be
displayed on the Driver's Information Center (DIC).
Lamps On Reminder
You will hear a warning chime if you open the driver's
door while leaving the lamps on and the exterior lamps
control is activated. An exception to this is when you're
using Twilight Sentinel or if the ignition is on.
Daytime Running Lamps
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.
The DRL system will make the high
-beam headlamps
come on at reduced brightness when:

the ignition is on,

the headlamp switch is off and

the transaxle is not in PARK (P).When DRL are on, only your high
-beam headlamps (at
reduced brightness) will be on. No other exterior lamps
such as the parking lamps, taillamps, etc. will be on
when the DRL are being used. Your instrument panel
won't be lit up either.
When the Twilight Sentinel
 switch is on and it's dark
enough outside, the high
-beam headlamps (at reduced
intensity) will turn off and normal low
-beam headlamp
operation will occur. When the Twilight Sentinel switch
is on and it's bright enough outside, the regular lamps
will go off, and the high
-beam headlamps at reduced
brightness will take over.
If it's dark outside and the Twilight Sentinel control is
off, a HEADLAMPS SUGGESTED message will
display on the Driver's Information Center (DIC). This
message informs the driver that turning on the exterior
lamps is recommended even though the DRL are still
illuminated. It has become dark enough outside to
require the headlamps and/or other exterior lamps.
Turning on the Twilight Sentinel or the headlamps will
deactivate the DRL and remove the HEADLAMPS
SUGGESTED message. If the parking lamps or the fog
lamps were turned on instead, the DRL will still
deactivate and the HEADLAMPS SUGGESTED
message will continue to be displayed.
