Automatic Headlamp System
When it is dark enough outside, the automatic headlamp
system turns on the headlamps at the normal brightness,
along with the taillamps, sidemarker, parking 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
it. For vehicles rst sold in Canada, the transmission
must be in the P (Park) position, before the automatic
headlamp system can be turned off.
The 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. Do not cover the
sensor or the headlamps will come 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 is only affected when the light sensor detects 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 bright enough 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 3-20.
To idle the vehicle with the automatic headlamp system
off, turn the control to the off position.
The headlamps will also stay on after you exit the
vehicle. This feature can be programmed using the
Driver Information Center (DIC). SeeDIC Vehicle
Customization (With DIC Buttons) on page 3-75.
The regular headlamp system can be turned on when
needed.

Puddle Lamps
If the vehicle has puddle lamps, they come on when the
unlock button on the Remote Keyless Entry (RKE)
Transmitter is pressed. The lamps time out or turn off
once the engine is started.
Fog Lamps
For vehicles with fog lamps, the control is located next
to the exterior lamps control on the instrument panel,
to the left of the steering column.
The ignition must be in the ON/RUN position for the fog
lamps to come on.
#(Fog Lamps):Press to turn the fog lamps on or off.
A light will come on in the instrument panel cluster.
When the fog lamps are turned on, the parking lamps
automatically turn on.
When the headlamps are changed to high-beam, the
fog lamps also go off. When the high-beam headlamps
are turned off, the fog lamps will come on again.
Some localities have laws that require the headlamps to
be on along with the fog lamps.
Auxiliary Roof-Mounted Lamp
If the 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 overhead console.
When the wiring is connected to an auxiliary roof
mounted lamp, pressing the bottom of the button will
activate the lamp and illuminate an indicator light at
the bottom of this button. Pressing the top of the button
will turn off the roof mounted lamp and indicator.
The emergency roof lamp circuit is fused at 30 amps, so
the total current draw of the attached lamps should be
less than this value. The attachment points for the roof
lamp circuits are two blunt cut wires located above the
overhead console, a dark green switched power wire and
a black ground wire.

Fuel Range
Press the trip/fuel button until FUEL RANGE displays.
This display shows the approximate number of remaining
miles (mi) or kilometers (km) the vehicle can be driven
without refueling. The display will show LOW if the fuel
level is low.
The fuel range estimate is based on an average of the
vehicle’s fuel economy over recent driving history and the
amount of fuel remaining in the fuel tank. This estimate
will change if driving conditions change. For example, if
driving in traffic and making frequent stops, this display
may read one number, but if the vehicle is driven on a
freeway, the number may change even though the same
amount of fuel is in the fuel tank. This is because different
driving conditions produce different fuel economies.
Generally, freeway driving produces better fuel economy
than city driving. Fuel range cannot be reset.
Average Economy
Press the trip/fuel button until AVG ECONOMY displays.
This display shows the approximate average miles per
gallon (mpg) or liters per 100 kilometers (L/100 km).
This number is calculated based on the number of mpg
(L/100 km) recorded since the last time this menu item
was reset. To reset AVG ECONOMY, press and hold the
set/reset button.
Fuel Used
Press the trip/fuel button until FUEL USED displays. This
display shows the number of gallons (gal) or liters (L) of
fuel used since the last reset of this menu item. To reset
the fuel used information, press and hold the set/reset
button while FUEL USED is displayed.
Timer
Press the trip/fuel button until TIMER displays. This
display can be used as a timer.
To start the timer, press the set/reset button while TIMER
is displayed. The display will show the amount of time
that has passed since the timer was last reset, not
including time the ignition is off. Time will continue to be
counted as long as the ignition is on, even if another
display is being shown on the DIC. The timer will record
up to 99 hours, 59 minutes and 59 seconds (99:59:59)
after which the display will return to zero.
To stop the timer, press the set/reset button briey while
TIMER is displayed.
To reset the timer to zero, press and hold the set/reset
