Rear Window Wiper/Washer
If your vehicle has a rear window washer/wiper,
the button is located on the instrument panel to the
left of the instrument panel cluster.
{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.
Z(Rear Wiper):Press this side of the button to
turn the rear wiper on and off. The wiper speed
cannot be changed.
Y(Wash):Press this button to spray washer uid on
the rear window. Release the button when enough
uid has been sprayed on the window. The rear wiper
will run a few more cycles after it is released. If the
rear wiper function was already on, prior to pressing
the wash button, it will stay on until the wiper button is
pressed again.
5(Delay):Press this side of the button to turn on
delayed wiping.
The rear window washer uses the same uid that is
in the windshield washer reservoir. SeeWindshield
Washer Fluid on page 5-35.

Cruise Control
{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.
With cruise control, a speed of about 25 mph (40 km/h)
or more can be maintained 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, cruise control is turned off.If your vehicle has the StabiliTrak
®system or Traction
Control system (TCS) and begins to limit wheel spin
while you are using cruise control, the cruise control will
automatically disengage. SeeStabiliTrak
®System on
page 4-7orTraction Control System (TCS) on page 4-5.
When road conditions allow you to safely use it again,
you can turn the cruise control back on.
The cruise control buttons
are located on the left side
of the steering wheel.
T(On/Off):This button can both activate and turn
off the system. The indicator light on the button turns
on when cruise control is on and turns off when
cruise control is off.
3-12

+ RES (Resume/Accelerate):Press this button to
make the vehicle accelerate or resume to a previously
set speed.
SET−(Set/Coast):Press this button to set the speed
or make the vehicle decelerate.
[(Cancel):Press this button to cancel cruise control
without erasing the set speed from memory.
Setting Cruise Control
Cruise control will not work if your parking brake is set
or if the master cylinder brake uid level is low.
The cruise control light on the instrument panel cluster
will come on after the cruise control has been set to
the desired speed.
{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. Press the cruise control On/Off button.
2. Get up to the desired speed.
3. Press the SET−button located on the steering
wheel and release it.
4. Take your foot off the accelerator.
3-13

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 you are driving about 25 mph (40 km/h) or
more, press the +RES button on the steering wheel.
The vehicle will return to the previously set speed
and stay there.
Increasing Speed While Using
Cruise Control
To increase the cruise speed while using cruise control:
Press and hold the +RES button on the steering
wheel until the desired speed is reached, then
release it.
To increase vehicle speed in small increments,
press the +RES button. Each time this is done,
the vehicle will go about 1 mph (1.6 km/h) faster.
Reducing Speed While Using
Cruise Control
To reduce the vehicle’s speed while using
cruise control:
Press and hold the SET– button on the
steering wheel until the desired lower
speed is reached, then release it.
To slow down in very small amounts,
press the SET– button on the steering
wheel briey. Each time this is done, the
vehicle will go about 1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase the vehicle’s
speed. When you take your foot off the pedal,
the vehicle will slow down to the previously set
cruise speed.
3-14

Using Cruise Control on Hills
How well your cruise control will work on hills depends
upon the vehicle’s speed, load, and the steepness
of the hills. When going up steep hills, you might
have to step on the accelerator pedal to maintain the
vehicle’s speed. When going downhill, you might have
to brake or shift to a lower gear to keep the vehicle’s
speed down. When the brakes are applied the cruise
control turns off. Many drivers nd this to be too much
trouble and do not 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 on the steering wheel.
Press theTbutton on the steering wheel.
Erasing Speed Memory
The cruise control set speed memory is erased when
the cruise control or the ignition is turned off.
Exterior Lamps
The exterior lamps
control is located on
the instrument panel
to the left of the
steering wheel.
It controls the following systems:
Headlamps
Taillamps
Parking Lamps
License Plate Lamps
Instrument Panel Lights
3-15

The exterior lamps control has four positions:
O(Off):Turn the control to this position to turn off the
automatic headlamps and daytime running lamps (DRL).
Turning the headlamp control to the off position again will
turn the automatic headlamps or DRL back on.
For vehicles rst sold in Canada, the off position will
only work for vehicles that are shifted into the PARK (P)
position.
AUTO (Automatic):Turn the control to this position
to automatically turn on the headlamps at normal
brightness, together with the following:
Parking Lamps
Instrument Panel Lights
Taillamps
License Plate Lamps
;(Parking Lamps):Turn the control to this position to
turn on the parking lamps together with the following:
Instrument Panel Lights
Taillamps
License Plate Lamps
2(Headlamps):Turn the control to this position to
turn on the headlamps together with the following lamps
listed below.
Parking Lamps
Instrument Panel Lights
Taillamps
License Plate Lamps
When the headlamps are turned on while the ignition is
on, the headlamps turn off automatically 10 minutes
after the ignition is turned off. When the headlamps are
turned on while the ignition is off, the headlamps will
stay on for 10 minutes before automatically turning off
to prevent the battery from being drained. Turn the
headlamp control to off and then back to the headlamp
on position to make the headlamps stay on for an
additional 10 minutes.
3-16

Headlamps on Reminder
If a door is open, a reminder chime will sound when
your headlamps or parking lamps are manually turned
on and your key is out of the ignition. To turn off
the chime, turn the headlamp switch to off or AUTO
and then back on, or close and re-open the door.
In the AUTO mode, the headlamps turn off once the
ignition is in LOCK or may remain on until the headlamp
delay ends (if enabled in the DIC). See “Exit Lighting”
underDIC Vehicle Customization (With DIC Buttons)
on page 3-63.
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 come on when the following
conditions are met:
The ignition is on.
The exterior lamps control is in AUTO.
The transmission is not in PARK (P).
The light sensor determines it is daytime.
When the DRL are on, only the DRL lamps will be on.
The taillamps, sidemarker, and other lamps will not
be on. The instrument panel will not be lit up either.
When it begins to get dark, the automatic headlamp
system will switch from DRL to the headlamps.
To turn off the DRL lamps, turn the exterior lamps
control to the OFF position and then release.
For vehicles rst sold in Canada, the transmission
must be in the PARK (P) position, before the
DRL lamps can be turned off.
3-17

Automatic Headlamp System
When it is dark enough outside and the headlamp
switch is in AUTO, the automatic headlamp system will
turn on the headlamps at the normal brightness along
with other lamps such as the taillamps, sidemarker,
parking lamps, roof marker lamps, and the instrument
panel lights. The radio lights will also be dim.
To turn off the automatic headlamp system, turn the
exterior lamps switch to the off position and then
release. For vehicles rst sold in Canada, the
transmission must be in the PARK (P) position, before
the automatic headlamp system can be turned off.
The vehicle has a light sensor located on the top of
the instrument panel. Be sure it is not covered,
or the system will be on whenever the ignition is on.
The system may also turn on the headlamps when
driving through a parking garage, heavy overcast
weather, or a tunnel. This is normal.
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.
If the vehicle is started in a dark garage, the automatic
headlamp system will come on immediately. Once
the vehicle leaves the garage, it takes approximately
one minute for the automatic headlamp system to
change to DRL if it is light outside. During that delay,
the instrument panel cluster may not be as bright
as usual. Make sure the instrument panel brightness
control is in the full bright position. SeeInstrument
Panel Brightness on page 3-18.
Instrument Panel Brightness
D(Instrument Panel Brightness):This feature
controls the brightness of the instrument panel lights
and is located next to the exterior lamp control.
Push the knob to extend out and then it can be turned.
Turn the knob clockwise or counterclockwise to
brighten or dim the instrument panel lights. Turning
the knob to the farthest clockwise position turns
on the dome lamps.
