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 208for 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. See
DIC Warnings and Messages on page 208for
more information.
SeeElectric Power Management on page 163for
more information.

Tire Pressure
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 or high tire pressure condition is detected
by the system while driving, a message advising
you to check the pressure in a speci c tire
will appear in the display. SeeIn ation - Tire
Pressure on page 409andDIC Warnings
and Messages on page 208for more information.
If the tire pressure display shows dashes
instead of a value, there may be a problem with
your vehicle. If this consistently occurs, see
your dealer for service.
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. See
Engine Oil on page 353. 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 462for 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 356. The display will show 100%
when the system is reset.

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 DIC buttons
on the uplevel vehicle 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 189. 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
RUN. Press any of the DIC buttons to acknowledge
this warning message and to clear it from the
screen.

power is reduced. Reduced engine power can
affect the vehicle’s ability to accelerate. If this
message is on, but there is no reduction in
performance, proceed to your destination. The
performance may be reduced the next time the
vehicle is driven. The vehicle may be driven at a
reduced speed while this message is on, but
acceleration and speed may be reduced. Anytime
this message stays on, the vehicle should be taken
to your dealer for service as soon as possible.
This message displays and a chime sounds only
when the ignition is in RUN. Press any of the
DIC buttons to acknowledge this message and to
clear it from the screen.
This message continues to display for two seconds
if it has not been acknowledged when the engine is
turned off. It also re-displays for two seconds if the
message has been acknowledged, but the
condition still exists when the engine is turned off.
If the condition still exists, the message re-appears
when the engine is turned on.

This message displays when your vehicle is in
an overheated engine operating mode. This
operating mode allows your vehicle to be driven to
a safe place in an emergency. In this mode,
you will notice a signi cant loss in power and
engine performance. SeeOverheated Engine
Protection Operating Mode on page 370for more
information. Anytime this message is on, the
vehicle should be taken to your dealer for service
as soon as possible.

when the ignition is in RUN. Press any of the
DIC buttons to acknowledge this message and to
clear it from the screen.
