When the headlamps are turned on while the vehicle is
on, the headlamps turn off automatically 10 minutes
after the ignition is turned off. When the headlamps are
turned on while the vehicle 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.
Push the turn signal/multifunction lever toward the
instrument panel to change the headlamps from low
beam to high beam.
Headlamps on Reminder
If a door is open, a reminder chime will sound when the
headlamps or parking lamps are manually turned on
and the 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/OFF 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 3-67.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the
day. 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 P (Park).
The light sensor determines it is daytime.
When the DRL are on, only the DRL lamps will be on.
The taillamps, sidemarker, instrument panel lights,
and other lamps will not be on.
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 P (Park) position, before the DRL lamps can
be turned off.
3-15

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 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. Do not cover this sensor or the
system 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 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 3-17.
Fog Lamps
If your vehicle has fog lamps you can use them for
better vision in foggy or misty conditions. Your parking
lamps and/or low-beam headlamps must be on for
your fog lamps to work.
The fog lamp button is located on the left side of your
instrument panel.
#(Fog Lamps):Press the button to turn the fog lamps
on. An indicator light will glow near the button when
the fog lamps are on. Press the button again to
turn them off.
Remember, fog lamps alone will not give off as much
light as your headlamps. Never use your fog lamps
in the dark without turning on the headlamps.

When the Light Flashes First and Then is
On Steady
This indicates that there could be a problem with the
Tire Pressure Monitor System. The light ashes
for about a minute and stays on steady for the remainder
of the ignition cycle. This sequence repeats with
every ignition cycle. SeeTire Pressure Monitor System
on page 5-64for more information.
Malfunction Indicator Lamp
Check Engine Light
A computer system called OBD II (On-Board
Diagnostics-Second Generation) monitors operation of
the fuel, ignition, and emission control systems. It
ensures that emissions are at acceptable levels for the
life of the vehicle, helping to produce a cleaner
environment.
This light should come on
when the ignition is on, but
the engine is not running,
as a check to show it
is working. If it does not,
have the vehicle serviced
by your dealer/retailer.If the check engine light comes on and stays on, while
the engine is running, this indicates that there is an
OBD II problem and service is required.
Malfunctions often are indicated by the system before
any problem is apparent. Being aware of the light
can prevent more serious damage to the vehicle. This
system assists the service technician in correctly
diagnosing any malfunction.
Notice:If the vehicle is continually driven with this
light on, after a while, the emission controls
might not work as well, the vehicle’s fuel economy
might not be as good, and the engine might not
run as smoothly. This could lead to costly repairs
that might not be covered by the vehicle warranty.
Notice:Modications made to the engine,
transmission, exhaust, intake, or fuel system of the
vehicle or the replacement of the original tires
with other than those of the same Tire Performance
Criteria (TPC) can affect the vehicle’s emission
controls and can cause this light to come on.
Modications to these systems could lead to costly
repairs not covered by the vehicle warranty. This
could also result in a failure to pass a required
Emission Inspection/Maintenance test. See
Accessories and Modifications on page 5-3.

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

Trip Odometer
Press the trip odometer reset stem until TRIP displays.
This display shows the current distance traveled in
either miles (mi) or kilometers (km) since the last reset
for the trip odometer.
The trip odometer can be reset to zero by pressing and
holding the trip odometer reset stem while the trip
odometer is displayed.
The trip odometer has a feature called the retro-active
reset. This can be used to set the trip odometer to
the number of miles (kilometers) driven since the ignition
was last turned on. This can be used if the trip
odometer is not reset at the beginning of the trip.
To use the retro-active reset feature, press and hold the
trip odometer reset stem for at least four seconds.
The trip odometer will display the number of miles (mi)
or kilometers (km) driven since the ignition was last
turned on and the vehicle was moving. Once the vehicle
begins moving, the trip odometer will accumulate
mileage. For example, if the vehicle was driven 5 miles
(8 km) before it is started again, and then the
retro-active reset feature is activated, the display will
show 5 miles (8 km). As the vehicle begins moving, the
display will then increase to 5.1 miles (8.2 km),
5.2 miles (8.4 km), etc.
Transmission Temperature
Press the trip odometer reset stem until TRANS TEMP
displays. This display shows the temperature of the
automatic transmission uid in either degrees
Fahrenheit (°F) or degrees Celsius (°C).
Trailer Gain and Output
On vehicles with the Integrated Trailer Brake Control
(ITBC) system, the trailer brake display appears in the
DIC. Press the trip odometer reset stem until TRAILER
GAIN and OUTPUT display.
TRAILER GAIN shows the trailer gain setting. This
setting can be adjusted from 0.0 to 10.0 with either a
trailer connected or disconnected. To adjust this setting,

underTowing a Trailer on page 4-47for more
information.
TRANSMISSION HOT IDLE ENGINE
Notice:If you drive your vehicle while the
transmission uid is overheating and the
transmission temperature warning is displayed on
the instrument panel cluster and/or DIC, you
can damage the transmission. This could lead to
costly repairs that would not be covered by
your warranty. Do not drive your vehicle with
overheated transmission uid or while the
transmission temperature warning is displayed.
This message displays along with a sound if the
transmission uid in the vehicle gets hot. Driving with
the transmission uid temperature high can cause
damage to the vehicle. Stop the vehicle and let it idle to
allow the transmission to cool. This message clears
and the chime stops when the uid temperature reaches
