Turn and Lane-Change Signals
An arrow on the instrument
panel cluster ashes in the
direction of the turn or
lane change.
Move the lever all the way up or down to signal a turn.
Raise or lower the lever for less than one second
until the arrow starts to ash to signal a lane change.
This causes the turn signals to automatically ash three
times. It will ash six times if tow-haul mode is active.
Holding the turn signal lever for more than one second
will cause the turn signals to ash until you release
the lever.
The lever returns to its starting position whenever it is
released.

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. See
Instrument Panel Brightness on page 3-18.
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 3-74.
The regular headlamp system can be turned on when
needed.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.

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.
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

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.

Compass Zone
The zone is set to zone eight upon leaving the factory.
Your dealer/retailer will set the correct zone for your
location.
Under certain circumstances, such as during a long
distance cross-country trip or moving to a new state or
province, it will be necessary to compensate for
compass variance by resetting the zone through the
DIC if the zone is not set correctly.
Compass variance is the difference between the earth’s
magnetic north and true geographic north. If the
compass is not set to the zone where you live, the
compass may give false readings. The compass must
be set to the variance zone in which the vehicle is
traveling.
