Rainsense™ II Wipers
If your vehicle has this feature, the moisture sensor is
mounted on the interior of the windshield below the
rearview mirror and is used to automatically operate
the wipers. This system operates by monitoring
the amount of moisture build-up on the windshield.
Wipes occur as needed to clear the windshield
depending on the driving conditions and the sensitivity
setting. In light rain or snow, fewer wipes will occur.
In heavy rain or snow, wipes will occur more frequently.
The system will operate in the delay, low speed and
high speed modes. If the system is left on for long
periods of time, occasional wipes may occur without
any moisture on the windshield. This is normal and
indicates that the Rainsense™ system is active.
The Rainsense™ system is activated by turning the
wiper control band to one of the ve sensitivity levels
within the delay area. The delay position closest to
OFF/MIST is the lowest sensitivity setting, level
one. This allows more rain or snow to collect on the
windshield between wipes. You can increase the
sensitivity of the system and the frequency of wipes by
turning the wiper control band away from you to thehigher sensitivity levels. The highest sensitivity setting,
level ve, is closest to the LO position. A single wipe
will occur each time you turn the wiper control band to a
higher sensitivity level to indicate that the sensitivity
level has been increased.
The windshield wipers also remain in a “high park”
position (the wipers are stopped on the windshield and
are not in the normal park position), even when the
ignition is turned off.
Notice:If you do not turn off the windshield wipers
when driving through an automatic car wash, you
could damage the wipers. Always turn off the
windshield wipers before entering an automatic
car wash.
The MIST and wash cycles operate as normal and
are not affected by the moisture-sensing function.
The system can be overridden at any time by manually
turning the wiper band 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.

If your vehicle is in cruise control when the optional
traction control system begins to limit wheel spin, the
cruise control will automatically disengage. SeeTraction
Control System (TCS) on page 4-9. 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 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. Move the cruise control
switch to ON.
2. Get up to the speed you want.
3. Push in the SET button at the end of the turn signal
lever and release it. The CRUISE light on the
instrument panel cluster will come on.
4. Take your foot off the accelerator pedal.
3-10

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 brake takes you out of cruise control.
Many drivers nd this to be too much trouble and do not
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. The CRUISE light
will also go out.
Erasing Speed Memory
When you turn off the cruise control or the ignition, your
cruise control set speed memory is erased.
Exterior Lamps
This control, located to the
left of the steering column,
operates the following
systems:
Headlamps
Taillamps
Parking Lamps
License Lamps
Sidemarker Lamps
Instrument Panel Lights
Interior Courtesy Lamps
3-12

OFF:Pushing the exterior lamps control all the way in
turns off all lamps and lights.
Parking Lamps:Pulling the exterior lamps control out
to the rst position turns on the parking lamps,
license plate lamps, the sidemarker lamps and the
instrument panel lights.
Headlamps:Pulling the exterior lamps control out to
the second position turns on the headlamps, together
with the previously listed lamps and lights.
For information on the interior lights, seeInterior Lamps
on page 3-15.
Headlamps On Reminder
If you leave the exterior lamp control on, remove the
key from the ignition and open the driver’s door, you will
hear a continuous warning chime. The chime will turn
off when the lamps are turned off.
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. Fully functional daytime
running lamps are required on all vehicles rst sold
in Canada.
A light sensor on top of the instrument panel monitors
the exterior light level for the operation of DRL and
Twilight Sentinel
®, so be sure it is not covered.
The DRL system will make your high-beam headlamps
come on at reduced brightness in daylight when the
following conditions are met:
The ignition is on.
The exterior lamps control is off.
The transaxle is not in PARK (P).
When DRL are on, only your high-beam headlamps will
be on. The parking lamps, taillamps, sidemarker and
other lamps will not be on. Your instrument panel will not
be lit up either.
3-13

When it is dark enough outside, your high-beam
headlamps will change to low-beam headlamps at full
brightness. The other lamps that turn on with your
headlamps will also turn on. When it is bright enough
outside, the regular lamps will turn off, and your
high-beam headlamps change to the reduced brightness
of DRL.
To idle your vehicle with the DRL off, shift the transaxle
into PARK (P). The DRL will stay off until you shift
out of PARK (P).
To turn off all exterior lighting at night when you are
parked, turn off the exterior lamp control and slide the
Twilight Sentinel
®control all the way to the left.
When released, the control will return to the Twilight
Sentinel
®minimum delay position and the lights will
turn off.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Cornering Lamps
The cornering lamps come on when the headlamps or
parking lamps are on and you signal a turn with the
multifunction lever. They provide more light for
cornering.
Twilight Sentinel®
Twilight Sentinel®turns
your headlamps on and off
by sensing how dark it
is outside.
To operate this feature, slide the control to any position
to vary the lamp time-out.
You can set the delay time from only a few seconds to
three minutes. If you move the control all the way to MAX,
your lamps will remain on for three minutes after you turn
off your engine. If you move the control almost all the way
in the other direction, so it is just on, the lamps will go off
quickly when you turn off your engine. Sliding the control
to OFF, turns off the Twilight Sentinel
®feature.
Light Sensor
Your Twilight Sentinel®and DRL work with the light
sensor on top of the instrument panel. Do not cover it
up. If you do, it will sense “dark” and the headlamps will
come on.
3-14

Interior Lamps
Instrument Panel Brightness
Adjust the instrument panel light brightness by turning
the exterior lamps control.
Courtesy Lamps
When any door is opened, several lamps go on.
They make it easy for you to enter and leave your vehicle.
You can also turn these lamps on by turning the exterior
lamps control clockwise all the way past the normal stop.
Entry Lighting
When you open either front door or press the unlock
button on the remote keyless entry transmitter, the lamps
inside your vehicle will turn on. These lamps will turn off
after about 40 seconds. These lamps will also turn off if
you start the engine or activate the power door locks.
Delayed Entry Lighting
When you open the door, the interior lamps will come on.
When you close the door with the ignition off, the interior
lamps will stay on for 25 seconds or until the ignition is
turned to an on position. Locking the doors with thepower door lock switch will override the delayed entry
lighting feature and the lamps will turn off right away.
Using the remote keyless entry transmitter to lock the
door will not cancel delayed lighting.
Theater Dimming
This feature allows for a three to ve-second fade out of
the courtesy lamps instead of immediate turn off.
Delayed Exit Lighting
With this feature, the interior lamps will come on for
25 seconds after you remove the key from the ignition.
This will give you time to nd the door handle or
lock switches.
Parade Dimming
This feature prohibits the dimming of your instrument
panel displays during daylight while your headlamps are
on. This feature operates with the light sensor for the
Twilight Sentinel
®and is fully automatic. When the light
sensor reads darkness outside, you will be able to
dim your instrument panel displays once again.

Glove Box Lamp
When you open the glove box, a lamp will come on
inside the glove box. This will automatically turn off when
the glove box is closed.
Battery Rundown Protection
This feature shuts off all lamps that are left on for more
than 10 minutes when the ignition is off. This will keep
your battery from running down.
Head-Up Display (HUD)
{CAUTION:
If the HUD image is too bright, or too high in
your eld of view, it may take you more time to
see things you need to see when it is dark
outside. Be sure to keep the HUD image dim
and placed low in your eld of view.
If your vehicle is equipped with the Head-Up Display
(HUD), you can see some of the driver information that
appears on your instrument panel cluster.The information may be displayed in English or metric
units and appears as a reection in the windshield.
The HUD consists of the following information:
Speedometer Reading
Turn Signal Indicators
High-Beam Headlamp Indicator
CHECK GAGES Message
The HUD shows these images when they are lighted on
the instrument panel cluster.
3-18

Be sure to continue scanning your displays, controls
and driving environment just as you would in a vehicle
without HUD. If you never look at your instrument
panel, you may not see something important, such as a
warning light.
Notice:If you try to use the HUD image as a
parking aid, you may misjudge the distance and
damage your vehicle. Do not use the HUD image as
a parking aid.
The HUD controls are
located in the overhead
console.1. Start your engine and slide the HUD dimmer switch
all the way up.
The brightness of the HUD image is determined by
whether the headlamps are on or off, and where
you have the HUD dimmer switch set.
2. Adjust the seat to a comfortable driving position.
Keep pressing the top arrow on the image height
adjuster to raise the image as far as possible.
3. Keep pressing the bottom arrow on the image
height adjuster to move the image as low as
possible, while still keeping it in full view.
4. Slide the dimmer switch downward until the HUD
image is no brighter than necessary.
To turn the HUD display off, slide the dimmer switch all
the way down.
If the sun comes out, the sky becomes cloudy, or if you
turn your headlamps on, you may need to adjust the
HUD brightness using the dimmer switch. Polarized
sunglasses could make the HUD image harder to see.
To change the display from English to metric units,
push the ENG/MET button located to the left of
the steering column.
3-19

Care of the HUD
Clean the inside of the windshield as necessary to
remove any dirt or lm that reduces the sharpness or
clarity of the HUD image.
To clean the HUD lens, spray household glass cleaner
on a soft, clean cloth. Gently wipe and dry the HUD
lens. Do not spray cleaner directly on the lens to avoid
cleaner leaking inside the unit.
If You Can’t See The HUD Image When
the Ignition is On
If the ignition is on and you can’t see the HUD image,
check to see if:
The headlamps are on.
Something is covering the HUD unit.
The HUD dimmer control is adjusted properly.
The HUD image is adjusted to the proper height.
A fuse is blown. SeeFuses and Circuit Breakers on
page 5-99.
Keep in mind that your windshield is part of the HUD
system. If you ever have to have your windshield
replaced, be sure to get one that is designed for HUD
or your HUD image may look blurred or out of focus.
Ultrasonic Rear Parking Assist
(URPA)
Your vehicle may be equipped with Ultrasonic Rear
Parking Assist (URPA). URPA is designed to help you
park while in REVERSE (R) and operates only at
speeds less than 3 mph (5 km/h). URPA can help you
avoid colliding with objects such as parked vehicles.
The system can detect objects 5 feet (1.5 m) behind
your vehicle and tell you how close those objects are to
your rear bumper.
The URPA display is located inside the vehicle, above
the rear window. It has three color-coded lights that can
be seen through the rearview mirror.
{CAUTION:
Even with the Ultrasonic Rear Park Assist
system, the driver must check carefully before
backing up. The system does not operate above
typical backing speeds of 3 mph (5 km/h) while
