Cleaning the System
The radar can become blocked by snow, ice, or dirt.
If so, you may need to turn off the engine and clean
the lens. See “Cleaning the System” underAdaptive
Cruise Control on page 3-19.
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 and hold the turn signal lever toward you to
use. When you do, the following will occur:
If the headlamps are either off or in the Daytime
Running Lamps (DRL) mode, the high-beam
headlamps will turn on. They will stay on as long
as you hold the lever there. Release the lever
to turn them off.
If the headlamps are on high beam, they will switch
to low beam. To return to high beam, push the
lever away from you.
Windshield Wipers
You control the windshield wipers by turning the band
with the wiper symbol on it.
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.
N(Delay):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.
6(Low Speed):For steady wiping at low speed,
turn the band away from you to the rst solid band
past the delay settings.
1(High Speed):For high-speed wiping, turn
the band further, to the second solid band past the
delay settings.
9(Off):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 are frozen to the windshield,
carefully loosen or thaw them. If your blades do become
worn or damaged, replace with 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.
Your vehicle is equipped with wiper-activated
headlamps. After the windshield wipers have been on
for approximately six seconds, the headlamps will
automatically turn on. SeeWiper Activated Headlamps
on page 3-34for more information.

Rainsense™ II Wipers
If your vehicle has this feature, the moisture sensor is
mounted on the interior side of the windshield behind the
rearview mirror. It is used to automatically operate the
wipers by monitoring the amount of moisture build-up
on the windshield. Wipes occur as needed to clear
the windshield depending on 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 Rainsense™ II wipers operate in a
delay mode as well as a continuous low or high speed
as needed. 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™ II system is activated.
The Rainsense™ II system can be activated by turning
the wiper band to one of the ve sensitivity levels
indicated on the wiper stalk. The position closest to off is
the lowest sensitivity setting, level one. This allows more
rain or snow to collect on the windshield between wipes.Turning the wiper band away from you to higher
sensitivity levels increases the sensitivity of the system
and frequency of wipes. The highest sensitivity setting,
level ve is closest to low. A single wipe will occur each
time you turn the wiper stalk to a higher sensitivity level
to indicate that the sensitivity level has been increased.
Notice:Going through an automatic car wash with
the wipers on can damage them. Turn the wipers
off when going through an automatic car wash.
The mist and wash cycles operate as normal and
are not affected by the Rainsense™ II function. The
Rainsense™ II system can be overridden at any time by
manually turning the wiper band to low or high speed.
When Rainsense™ II is active, the headlamps will
turn on automatically. The headlamps will turn off
again once the wipers turn off if it is light enough
outside. If it is dark, they will remain on. SeeWiper
Activated Headlamps on page 3-34for more information.
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
{CAUTION:
In freezing weather, do not use your washer
until the windshield is warmed. Otherwise the
washer uid can form ice on the windshield,
blocking your vision.
J(Washer Fluid):Press and release this paddle,
located at the top of the turn signal/multifunction lever,
to spray washer uid on the windshield. The wipers
will clear the windshield and either stop or return to your
preset speed. For more washer cycles, press and
hold the paddle.
_(Heated Washer Fluid):If your vehicle is equipped,
the heated windshield washer uid system may be
used to help clear ice, snow, tree sap, or bugs from
your windshield. Sliding the switch on the turn signal/
multifunction lever to this position and then releasing
it will activate the heated windshield washer uid system.
This activation will initiate four heated wash/wipe cycles.
The rst heated wash/wipe cycle may take up to
40 seconds to occur, depending on outside temperature.
After the rst wash/wipe cycle, it may take up to
20 seconds for each of the remaining cycles. The heated
windshield washer uid system may be turned off at any
time by sliding the switch on the turn signal/multifunction
lever to this position again.
When the heated windshield washer uid system is
activated under certain outside temperature conditions,
steam may ow out of the washer nozzles for a short
period of time before washer uid is sprayed. This is a
normal condition.
A message will be displayed on the Driver Information
Center (DIC) when the washer uid is low. SeeDIC
Warnings and Messages on page 3-76.

Cruise Control
With cruise control, you can maintain a speed of
approximately 25 mph (40 km/h) or more without
keeping your foot on the accelerator. This is helpful 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 cruise light on the instrument
panel cluster.
When you apply your brakes, the cruise control
shuts off.
{CAUTION:
Cruise control can be dangerous where you
cannot 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 excessive wheel slip, 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 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.
3-16

The cruise control buttons
are located on left side of
the steering wheel.
I(On):This position activates the system.
+ RES (Resume/Accelerate):Press this button to
make the vehicle accelerate or resume to a previously
set speed.
–SET (Set):Press this button to set the speed.
[(Cancel):Press this button to cancel cruise control.
Cruise control will not work if your parking brake is
set, or if the master cylinder brake uid level is low.
If you apply your brakes, the cruise control will shut off.The cruise light on the instrument panel cluster will
come on after the cruise control has been set to
the desired speed.
1. Press the cruise control button.
2. Get up to the speed you want.
3. Press the SET button located on the steering wheel
and release it.
4. Take your foot off the accelerator.
Resuming a Set Speed
Suppose you set your cruise control at a desired speed
and then you apply the brake. This shuts off the
cruise control. But you do not need to reset it.
Once the vehicle is traveling approximately
25 mph (40 km/h) or more, you can press the
RES (resume/accelerate) button to return to your
desired preset speed. The cruise light will be displayed
again.
The vehicle will return to and stay at your preset speed.
If you press and hold the RES button, the vehicle
speed will increase until you release the button or apply
the brake. Unless you want to go faster, do not press
and hold the RES button.
3-17

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 SET button, then release the
button and the accelerator pedal. You will
now cruise at the higher speed.
Press the RES button. Hold it there until you get up
to the speed that you want, and then release the
button. To increase your speed in very small
amounts, briey press the RES button and then
release it. Each time you do this, your vehicle will
speed up approximately 1 mph (1.6 km/h).
The accelerate feature will only work after you have set
the cruise control speed by pressing the SET button.
Reducing Speed While Using Cruise
Control
There are two ways to reduce your speed while using
cruise control:
Press the SET button until you reach the lower
speed you want, then release it.
To slow down in very small amounts, push the SET
button briey. Each time you do this, the vehicle will
slow down approximately 1 mph (1.6 km/h).
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.
3-18

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. Applying the
brake or shifting into a lower gear will take you out
of cruise control. If you need to apply the brake or shift
to a lower gear due to the grade of the downhill
slope, you may not want to attempt to use your cruise
control feature.
Ending Cruise Control
To turn off the cruise control, step lightly on the brake
pedal, or press the cancel button on the steering wheel.
Erasing Speed Memory
When you turn off the cruise control or the ignition, your
cruise control set speed memory is erased.

3-19

Adaptive Cruise Control is an enhancement to traditional
cruise control. It allows you to keep cruise control
engaged in moderate traffic conditions without having to
constantly reset your cruise control. Adaptive Cruise
Control uses radar to detect a vehicle directly ahead in
your path, within a distance of 330 ft (100 m), and
operates at speeds above 25 mph (40 km/h). When it is
engaged by the driver, the system can apply limited
braking or acceleration of the vehicle automatically to
maintain a selected follow distance to the vehicle
ahead. Braking is limited to 0.25 g’s (2.45 m/sec2) of
deceleration, which is comparable to moderate
application of the vehicle’s brakes. To disengage
Adaptive Cruise Control, apply the brake. If no vehicle
is in your path, your vehicle will react like traditional
cruise control.
{CAUTION:
Adaptive Cruise Control will not apply hard
braking or bring the vehicle to a complete
stop. It will not respond to stopped vehicles,
pedestrians or animals. When you are
approaching a vehicle or object, Adaptive
Cruise Control may not have time to slow your
vehicle enough to avoid a collision. Your
complete attention is always required while
driving and you should be ready to take action
and apply the brakes. For more information,
seeDefensive Driving on page 4-2.
