Shift the transmission to NEUTRAL (N).
Hold the accelerator pedal for 60 seconds or
longer.
Erasing Speed Memory
When you turn off the cruise control or the

erased.
Headlamps
The control on the driver’s side of your instrument
panel operates the headlamps.
221

The headlamp control has four positions:
9(Off):Turn the control to this position to turn
off the Daytime Running Lamps (DRL) and
the automatic headlamps.
AUTO (Automatic):Turn the control to this
position to activate the automatic headlamp mode.
;(Parking Lamps):Turn the control to this
position to turn on the parking lamps, together with
the following:
Sidemarker Lamps
Taillamps
License Plate Lamps
Instrument Panel Lights
Roof Marker Lamps (If the vehicle has them)
5(Headlamps):Turn the control to this position
to turn on the headlamps, together with the
previously listed lamps and lights.Switch the headlamps from high to low-beam by
pushing the turn signal/high-beam lever towards
the instrument panel.
A circuit breaker protects the headlamps. If you
have an electrical overload, the headlamps
will icker on and off. Have your headlamp wiring
checked right away if this happens.
Headlamps on Reminder
A reminder chime will sound when the headlamps
or parking lamps are manually turned on and
your ignition is off and a door is open. To disable
the chime, turn the light 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 DRL are required on all
vehicles rst sold in Canada.
222

The DRL system will come on when the following
conditions are met:
The ignition is on
The exterior lamps control is in AUTO
The light sensor determines it is daytime
When the DRL are on, only your DRL lamps will
be on. The taillamps, sidemarker, and other lamps
will not be on. The instrument panel back
lighting will not be on either.
When it begins to get dark, the automatic
headlamp system will switch from DRL to the
headlamps.
When you turn the headlamp switch off, the
headlamps will go off.
Automatic Headlamp System
When it is dark enough outside, the automatic
headlamp system will turn on the headlamps at the
normal brightness, along with the taillamps,
sidemarker, parking lamps, and the instrument
panel lights. The radio back lighting will also
be dimly lit.
To turn off the automatic headlamp system, turn
the exterior lamps switch to the off position.
Turning off the automatic headlamp system with
the headlamp switch is not available for vehicles
rst sold in Canada.
Your vehicle has a light sensor located on the top
of the instrument panel in the defroster grille
that regulates when the automatic headlamps turn
on. Be sure it is not covered, or the headlamps
will come on whenever the ignition is on.
223

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 detects a change
in lighting lasting longer than the delay.
If you start your vehicle in a dark garage, the
automatic headlamp system will come on
immediately. Once you leave the garage, it will
take approximately one minute for the automatic
headlamp system to change to DRL if it is
bright enough outside. During that delay, your
instrument panel cluster may not be as bright as
usual. Make sure your instrument panel brightness
control is in the full bright position. SeeInstrument
Panel Brightness on page 226.To idle your vehicle with the automatic headlamp
system off, turn the control to the off position.
You may be able to turn off your Automatic
Headlamp System. SeeDaytime Running Lamps
(DRL) on page 222for more information.
Your headlamps will also stay on after you exit the
vehicle. You can program this feature using the
Driver Information Center (DIC). SeeDIC Vehicle
Customization on page 282.
As with any vehicle, you should turn on the
regular headlamp system when needed.
224

Fog Lamps
If your vehicle has fog lamps, use them for better
vision in foggy or misty conditions.
The fog lamp button is
located on the left side
of the instrument
panel.
The parking lamps and/or low-beam headlamps
must be on for the fog lamps to work.
Press the button to turn the fog lamps on or off.
An indicator light will glow in the button when
the fog lamps are on.Remember, fog lamps alone will not give off as
much light as the headlamps. Never use the
fog lamps in the dark without turning on the
headlamps.
The fog lamps will go off whenever the high-beam
headlamps come on. When the high beams go
off, the fog lamps will come on again.
The fog lamps will be cancelled after the ignition is
turned off. If you still want to use the fog lamps
after you restart the vehicle, you will need to press
the fog lamp button again.
Some localities have laws that require the
headlamps to be on along with the fog lamps.
225

Auxiliary Roof Mounted Lamp
If your vehicle has this feature, this button includes
wiring provisions for a dealer or a qualied
service center to install an auxiliary roof lamp.
This button is located
on the center of the
instrument panel near
the climate controls.
When the wiring is connected to an auxiliary roof
mounted lamp, pressing the button will activate
the lamp and illuminate an indicator light near the
button. Pressing the button again will turn off
the roof mounted lamp.
If your vehicle has this button, your vehicle may
have the snow plow prep package. For further
information seeAdding a Snow Plow or Similar
Equipment on page 416.
Instrument Panel Brightness
D(Instrument Panel Brightness):This feature
controls the brightness of the instrument panel
lights.
The thumbwheel for this feature is located next to
the headlamp control.
Move the thumbwheel up to adjust the instrument
panel lights and to return the radio display to
full brightness when the headlamps or parking
lamps are on. To turn on the dome lamps, move
the thumbwheel to the farthest position.
Dome Lamps
The dome lamps come on when a door is opened.
The dome lamps can be turned on by moving
the thumbwheel, located next to the exterior lamps
control, to the farthest position. In this position,
the dome lamps will remain on whether a door is
opened or closed.
226

When AUTO is selected, the air conditioning
operation and air inlet will be automatically
controlled. The air conditioning compressor will
run when the outside temperature is over
about 40°F (4°C). The air inlet will normally be
set to outside air. If it is hot outside, the air
inlet may automatically switch to recirculate
inside air to help quickly cool down your
vehicle. The light on the button will come on in
recirculation.
2. Set the driver’s and passenger’s temperature.
To nd your comfort setting, start with a 74°F
(23°C) temperature setting and allow about
20 minutes for the system to regulate. Turn the
driver’s or passenger’s side temperature
knob to adjust the temperature setting as
necessary. If you choose the temperature
setting of 60°F (15°C) the system will remain
at the maximum cooling setting. If you
choose the temperature setting of 90°F (32°C)
the system will remain at the maximum
heat setting. Choosing either maximum setting
will not cause the vehicle to heat or cool
any faster.Be careful not to cover the solar sensor
located on the top of the instrument panel
near the windshield. This sensor regulates air
temperature based on sun intensity. It also
turns on the headlamps. For more information
on the solar sensor, see “Sensors” later in
this section.
To avoid blowing cold air in cold weather, the
system will delay turning on the fan until
warm air is available. The length of delay
depends on the engine coolant temperature.
Pressing the fan switch will override this delay
and change the fan to a selected speed.
9(Off):Press this button to turn off the entire
climate control system. Outside air will still
enter the vehicle, and will be directed to the oor.
This direction can be changed by pressing the
mode button. The temperature can also be
adjusted using either temperature knob. Press the
up or down arrows on the fan switch, the defrost
button, the AUTO button, or the air conditioning
button to turn the system on when it is off.
