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)
2
(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.

DIC Warnings and Messages
Messages are displayed on the uplevel DIC to notify the
driver that the status of the vehicle has changed and that
some action may be needed by the driver to correct the
condition. Multiple messages may appear one after
another.
Some messages may not require immediate action,
but you can press any of the uplevel DIC buttons to
acknowledge that you received the message and
clear it from the DIC display.
Some messages cannot be cleared from the DIC
display because they are more urgent. These messages
require action before they can be cleared.
If there are any active warning messages when the
vehicle is turned off, two chimes sound and the DIC goes
into a reminder mode. The reminder mode displays any
active message. If there are multiple messages, the DIC
displays each message for ve seconds. After each
active message is displayed once, the reminder mode
turns off.
You should take any messages that appear on the
display seriously and remember that clearing the
messages will only make the messages disappear,
not correct the problem.
The following are the possible messages that can be
displayed and some information about them.
A/C OFF FOR ENGINE PROTECTION
This message displays when the engine coolant
becomes hotter than the normal operating temperature.
SeeEngine Coolant Temperature Gage on page 3-38.
To avoid added strain on a hot engine, the air
conditioning compressor is automatically turned off.
When the coolant temperature returns to normal, the
air conditioning compressor turns back on. You can
continue to drive your vehicle.
This message comes on while the ignition is in ON/RUN.
Press any of the DIC buttons to acknowledge this
warning message and to clear it from the screen.
This message continues to display for two seconds

when the engine is turned on. If this message continues
to appear, have the system repaired by your dealer/
retailer as soon as possible to avoid damage to the
engine.

Light on page 3-47. Check the fuel cap to ensure that it is
on properly. The diagnostic system can determine if the
fuel cap has been left off or improperly installed. A loose
or missing fuel cap allows fuel to evaporate into the
atmosphere. A few driving trips with the cap properly
installed should turn this message off. SeeFilling the

(TPMS), this message displays when the pressure in one
or more of the vehicle’s tires needs to be checked. This
message also displays LEFT FRONT, RIGHT FRONT,
LEFT REAR, or RIGHT REAR to indicate which tire
needs to be checked. You can receive more than one tire
pressure message at a time. To read the other messages
that may have been sent at the same time, press the
set/reset button. If a tire pressure message appears on
the DIC, stop as soon as you can. Have the tire pressures
checked and set to those shown on the Tire Loading
Information label. SeeTires on page 5-54,Loading the
Vehicle on page 4-20, andInflation - Tire Pressure on
