Engine Coolant Temperature Gage
This gage shows the engine coolant temperature.
If the gage pointer moves towards the “H”
(United States) or the shaded in thermostat
(Canada), it means that your engine coolant has
overheated. If you have been operating your
vehicle under normal driving conditions, you should
pull off the road, stop your vehicle and turn off
the engine as soon as possible.
SeeEngine Overheating on page 323for more
information.
Tire Pressure Light
This light comes on
briey when you turn
the ignition to RUN.
This light will also come on when one or more of
your tires are signicantly underinated.
A CHECK TIRE PRESSURE message in the
Driver Information Center (DIC) will accompany
the light. SeeDIC Warnings and Messages
on page 199for more information.
Stop and check your tires as soon as it is safe to
do so. If underinated, inate to the proper
pressure. SeeTires on page 351for more
information.

Fuel Gage
When the ignition is on, the fuel gage tells you
about how much fuel you have remaining.
Here are four things that some owners ask about.
None of these show a problem with your fuel gage:
At the gas station, the gas pump shuts off
before the gage reads full.
It takes a little more or less fuel to ll up than
the gage indicated. For example, the gage may
have indicated the tank was half full, but it
actually took a little more or less than half the
tank’s capacity to ll the tank.
The gage moves a little when you turn a corner
or speed up.
The gage doesn’t go back to empty when you
turn off the ignition.
Driver Information Center (DIC)
Your vehicle has a Driver Information Center (DIC).
All messages will appear in the DIC display
located below the speedometer in the instrument
panel cluster. The DIC buttons are located on
the instrument panel, to the right of the instrument
panel cluster.
The DIC comes on when the ignition is on. After a
short delay, the DIC will display the information
that was last displayed before the engine was
turned off.
The DIC displays trip, fuel, and vehicle system
information, and warning messages if a system
problem is detected. The bottom line of the
DIC shows the shift lever position indicator. See
Automatic Transaxle Operation on page 116
for more information.

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 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.If your vehicle is low on fuel, the FUEL LEVEL
LOW message will be displayed. See “FUEL
LEVEL LOW” underDIC Warnings and Messages
on page 199for more information.
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. The display will return to zero.

scroll through the following menu items:
Oil Life
Press the vehicle information button until OIL LIFE
REMAINING displays. This display shows an
estimate of the oil’s remaining useful life. If you
see 99% OIL LIFE REMAINING on the display,
that means 99% of the current oil life remains.
The engine oil life system will alert you to change
the oil on a schedule consistent with your
driving conditions.
When the remaining oil life is low, the CHANGE
ENGINE OIL SOON message will appear on the
display. See “CHANGE ENGINE OIL SOON”
underDIC Warnings and Messages on page 199.
You should change the oil as soon as possible.
SeeEngine Oil on page 310. In addition to the
engine oil life system monitoring the oil life,
additional maintenance is recommended in the
Maintenance Schedule in this manual. See
Scheduled Maintenance on page 408for 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 314.
