2. If the engine does not start after 5-10 seconds,
especially in very cold weather (below 0°F or−18°C),
it could be ooded with too much gasoline. Try
pushing the accelerator pedal all the way to the oor
and holding it there as you hold the key in START for
up to a maximum of 15 seconds. Wait at least
15 seconds between each try, to allow the cranking
motor to cool down. When the engine starts, let go of
the key and accelerator. If the vehicle starts briey
but then stops again, repeat these steps. This clears
the extra gasoline from the engine. Do not race the
engine immediately after starting it. Operate the
engine and transmission gently until the oil warms up
and lubricates all moving parts.
Notice:The engine is designed to work with the
electronics in the vehicle. If you add electrical parts
or accessories, you could change the way the
engine operates. Before adding electrical equipment,
check with your dealer/retailer. If you do not, the
engine might not perform properly. Any resulting
damage would not be covered by the vehicle
warranty.Engine Coolant Heater
The engine coolant heater can provide easier starting
and better fuel economy during engine warm-up in cold
weather conditions at or below 0°F (−18°C). Vehicles
with an engine coolant heater should be plugged
in at least four hours before starting. Some models have
an internal thermostat in the cord which will prevent
engine coolant heater operation at temperatures above
0°F (−18°C).
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. The
cord is attached to the underside of the diagonal
brace, which is located above the engine air
cleaner/lter assembly.
3. Plug it into a normal, grounded 110-volt AC outlet.
2-24

{CAUTION:
Plugging the cord into an ungrounded outlet could
cause an electrical shock. Also, the wrong kind of
extension cord could overheat and cause a re.
You could be seriously injured. Plug the cord into
a properly grounded three-prong 110-volt AC
outlet. If the cord will not reach, use a heavy-duty
three-prong extension cord rated for at least
15 amps.
4. Before starting the engine, be sure to unplug and
store the cord as it was before to keep it away
from moving engine parts, and prevent damage.
The length of time the heater should be plugged in
depends on several factors. Ask a dealer/retailer in the
area where you will be parking the vehicle for the
best advice on this.
Active Fuel Management™
The vehicle’s V8 engine may have Active Fuel
Management™. This system allows the engine to
operate on either all or half of its cylinders, depending
on driving conditions.
When less power is required, such as cruising at a
constant vehicle speed, the system will operate in the
half cylinder mode, allowing the vehicle to achieve better
fuel economy. When greater power is required, such
as accelerating from a stop, passing, or merging onto a
freeway, the system will maintain full-cylinder operation.

mode helps to prevent the air inside the vehicle from
becoming stale. After ve minutes recirculate will allow
some outside air into the vehicle.
)(Bi-Level):Air is divided between the instrument
panel and oor outlets. Some air may be directed toward
the windshield. Slightly cooler air is directed to the
instrument panel outlets and warmer air is directed
to the oor outlets.
6(Floor):Air is directed to the oor outlets, with
some air directed toward the side window outlets and
windshield.
In this mode, the system automatically uses outside air.
The air conditioning compressor will be engaged unless
the outside temperature is 40°F (4°C) or below.

h(Recirculate):Press to turn the recirculation mode
on. An indicator light comes on to show that recirculation
is on. This mode recirculates and helps to quickly heat or
cool the air inside the vehicle. It can be used to prevent
the outside air and odors from entering the vehicle.
Operation in this mode during periods of high humidity
and cool outside temperatures may result in increased
window fogging. If window fogging is experienced, select
the defrost mode. To prevent the air inside the vehicle
from becoming stale, after ve minutes recirculation lets
some outside air into the vehicle.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.

The outside air temperature automatically appears in
the bottom right corner of the uplevel DIC display when
viewing the trip/odometer screens, fuel screens and
some of the gages screens. If the outside air temperature
is at or below 37°F (3°C), the temperature reading will
toggle between displaying the outside temperature and
the word ICE for two minutes. If there is a problem with
the system that controls the temperature display, the
letters OC (open circuit) or SC (short circuit) will appear
on the display. If this occurs, have the vehicle serviced
by your dealer/retailer.
The uplevel DIC also allows some features to be
customized or personalized. SeeDIC Vehicle
Personalization on page 3-74for more information.
DIC Operation and Displays
The DIC has different modes which can be accessed by
pressing the DIC buttons located on the center of the
instrument panel. Depending on whether your vehicle
has the base level or uplevel DIC, the buttons and
modes available will differ.
The base level buttons are the trip/odometer and
English/Metric buttons.
The uplevel buttons are the trip/odometer, fuel, gages,
set/reset, and option buttons.
The button functions are detailed in the following pages.
DIC Buttons
TRIP/ODO (Trip/Odometer):For vehicles with the
base level DIC, press this button to display the odometer
and trip distance.
For vehicles with the uplevel DIC, press this button
to display the odometer, trip distance, time elapsed,
and average speed.

There is also a retroactive trip odometer function that
performs the following for each trip odometer:
If the vehicle’s speed has exceeded 3 mph (5 km/h)
during the current ignition cycle, this function will
set the trip odometer to the distance driven
during the current ignition cycle.
If the vehicle’s speed has not exceeded 3 mph
(5 km/h), this function will set the trip odometer
to the distance driven during the previous ignition
cycle plus the distance driven during the current
ignition cycle.
Press and hold the set/reset button on vehicles with
the uplevel DIC or the trip/odometer button on vehicles
with the base level DIC for three seconds, then release
the button. The retroactive trip odometer value will be set
into the currently displayed trip odometer.
Time Elapsed (Uplevel Only)
Press the trip/odometer button until TIME ELAPSED :00
displays. This mode is like a stopwatch, in that you can
clock the time it takes to get from one point to another.
Each of the elds for the hours, minutes, and seconds
are two numeric digits.Once TIME ELAPSED :00 is displayed, press the
set/reset button on vehicles with the uplevel DIC to start
the timing feature. Press the set/reset button again to
stop it. If you will be starting and stopping your vehicle,
during a trip for instance, the TIME ELAPSED feature will
automatically start timing where it left off when you last
stopped. To reset it, press and hold the set/reset button
for about 1.5 seconds. The display will return to zero.
Press the trip/odometer button to exit from the TIME
ELAPSED display.
Average Speed (Uplevel Only)
Press the trip/odometer button until AVERAGE SPEED

Fuel Menu Items (Uplevel Only)
.
(Fuel):Press this button to scroll through the
following menu items:
Fuel Range
Press the fuel button until FUEL RANGE displays.
This mode shows the approximate number of remaining
miles or kilometers the vehicle can be driven without
refueling.
Fuel range is based on several factors, including
distance traveled, fuel used, fuel capacity, etc.
This estimate will change if driving conditions change.
For example, if driving in traffic and making frequent
stops, this mode 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.
If your vehicle is low on fuel, FUEL RANGE LOW will
display followed by the LOW FUEL message. See “LOW
FUEL” underDIC Warnings and Messages on page 3-56
for more information.
Average Fuel Economy
Press the fuel button until AVG ECONOMY displays.
This mode 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. The display will return to zero.
Gages Menu Items (Uplevel Only)

(Gages):Press this button to scroll through the
following menu items:
Battery
Press the gages button until BATTERY displays.
This mode shows the current battery voltage.
Your vehicle’s charging system regulates voltage based
on the state of the battery. The battery voltage may
uctuate when viewing this information on the DIC.
This is normal.
If there is a problem with the battery charging system,
a DIC message will display. SeeDIC Warnings and
Messages on page 3-56for more information.
SeeElectric Power Management on page 3-18for more
information.
3-51

Oil Life
Press the gages button until OIL LIFE displays. This
mode shows an estimate of the oil’s remaining useful
life. If you see OIL LIFE 99% on the display, that means
99% of the current oil life remains. The engine oil life
system will alert you to change your oil on a schedule
consistent with your driving conditions.
When the remaining oil life is low, the CHANGE OIL
SOON message will appear on the display. You should
change your oil as soon as possible. SeeEngine Oil
on page 5-15. In addition to the engine oil life system
monitoring the oil life, additional maintenance is
recommended in the Maintenance Schedule in this
manual. SeeScheduled Maintenance on page 6-4
for more information.
Remember, you must reset the OIL LIFE yourself after
each oil change. It will not reset itself. Also, be careful not
to reset the OIL LIFE accidentally at any time other than
when the oil has just been changed. It cannot be reset
accurately until the next oil change. To reset the engine
oil life system, seeEngine Oil Life System on page 5-18.
The display will show 100% when the system is reset.
Tire Pressure
On vehicles with the Tire Pressure Monitor System
(TPMS), press the gages button until FRONT TIRE
PRESSURE displays. This mode shows the pressure
for the front tires. To view the pressure for the rear
tires, press the gages button again until REAR TIRE
PRESSURE displays. The tire pressure will be shown in
either pounds per square inch (psi) or kilopascals (kPa).
If a low tire pressure condition is detected by the
system while driving, a message advising you to check
the pressure in a specic tire will appear in the display.
SeeInflation - Tire Pressure on page 5-61andDIC
Warnings and Messages on page 3-56for more
information.
If the tire pressure display shows dashes or blanks
instead of a value, there may be a problem with
your vehicle. If this consistently occurs, see your
dealer/retailer for service.
