Analog Cluster Digital Cluster
The fuel gage shows approximately how much fuel is in
the tank. It works only when the ignition is
in RUN.
On the digital cluster, if the fuel level is within
approximately 2 gallons (7.6 L) of being full, the letter F is
shown. If the fuel level is less than approximately
3 gallons (1 1.4 L) from being empty, the letter E is shown.
If the fuel supply gets down to approximately 3 gallons
(11.4 L), the number “3” will be displayed on the fuel
gage, and the
FUEL LEVEL LOW message will appear
on the Driver Information Center
@IC). (On the analog
fuel gage, the
FUEL LEVEL LOW message will
also appear.)
Here are a few concerns some owners have had about
the fuel gage. All
of these situations are normal and do
not indicate that anything is wrong with the fuel gage:
At the gas station the gas pump shuts off before the
gage reads
E
It takes more (or less) gas to fill the tank than the
gage said. For example, the gage read
8 GALLONS
(30 L), but it took more (or less) than the tank’s
remaining capacity to fill it.

mile-per-gallon (AVG MPG).
You can also display it in
metric units by pressing the ENG MET button.

When AVG MPG is selected, the total distance is
divided by the total fuel used.
When the INST button (Instantaneous Fuel Economy) is
selected, you will see what the fuel economy is at that
instant. The computer takes a new reading twice every
second. It will show economy up to
70 miles-per-gallon
(or
2 L per 100 km).
To reset the average fuel economy, press the INFORMATION button until the AVG MPG is
displayed on the Driver Information Center (DIC). Press and hold the
RESET button until both the fuel data
center and DIC display reads
0.0.
Digital Cluster
For vehicles equipped with an analog cluster (not shown), fuel data can be obtained by pressing the
INFO button. See “Analog Control Buttons’’ later
in this section.
The fuel data panel tells you all you need to know about
the fuel economy and how far you can travel with the
he1 remaining. The
RANGE display shows how far the computer thinks
you can travel with the fuel that is in the tank. The
computer does not know what driving conditions will be
like for the rest of your trip,
so the range is estimated
based on the recent fuel economy. Therefore,
the range
reading may change as your driving habits change. Going from city to highway driving may increase the
range reading.
If the range display shows
LO, you should stop for fuel
as soon as possible.

DIC Messages
These messages will appear if there is a problem sensed
in one of your vehicle’s systems. Vehicles that are first
sold in Canada will have a number after each message.
This number helps to identify the message which is only
displayed in English.
APPLY BRAKE TO SHIFT - 46: This message will
appear
if your vehicle is in PARK (P) for about 15
seconds and the brake is not pressed in. To remove this
message from the Driver Information Center (DIC)
display, hold the
OFF and the blue (cooler) buttons on
the digital cluster control panel for about five seconds.
On the analog climate control panel, press the
OFF
button (next to the MODE button) and the down arrow
on the PASS TEMP button for about five seconds. Hold
the same two buttons to display the message again.
BATTERY NOT CHARGING - 7: This message will
appear if the battery is not.being charged. Have the

warning light is on, follow the directions in that part.
CHECK COOLANT LEVEL - 2: This message
will appear when there is a low level of engine coolant.
Have the cooling system serviced by a technician as
soon as possible.
CHECK FUEL GAUGE - 39: This message will
appear when the
fuel supply is less than 4 gallons
(15.2 L) and the display is turned off (digital clusters
only).
A single chime will also sound when this message
is displayed.
CHECK GAS CAP - 61: This message will appear if
the gas cap has not been fully tightened.
You should
recheck your gas cap to ensure that it’s fully tightened.
CHECK OIL LEVEL - 36: For correct operation of
the low oil sensing system, your vehicle should be on a
level surface. A false
CHECK OIL LEVEL message
may appear if the vehicle is parked on grades. The oil
level sensing system does not check for actual oil level
if the engine has been off for a short period of time, and
the oil level is never sensed while the engine is running.
If the
CHECK OIL LEVEL message appears, and your
vehicle has been parked on level ground with the engine
off for at least 30 minutes, the oil level should be
checked by observing the oil dipstick. Prior to checking
the oil level, be sure the engine has been
off for five minutes and your vehicle is on a level surface. Then
check the dipstick and add oil if necessary. See “Engine
Oil’’
in the Index.
CHECK WASHER FLUID - 25: This message will
appear for several seconds indicating that
you need
washer solvent.

appear for a few seconds when you select a speed at
which to cruise.
DOOR A JAR - 141: A door other than the driver’s
door is open or ajar when this message appears. The
vehicle’s engine must be running and the transaxle not
in PARK (P) for this message to display. A chime will
also sound when the vehicle’s speed
is greater than
5 mph (8 km/h).
DRIVER DOOR A JAR - 140: This message will
display when the vehicle is being shifted out of
PARK (P) with the engine running to signal that the
driver’s door is open or ajar.
A chime will also sound
when the vehicle’s speed is greater than
5 mph (8 km/h).
ENGINE COOLANT HOT, IDLE ENGINE - 44:
This message will appear when the engine coolant
temperature is over
248 “F (1 26 O C). To avoid added
strain on a hot engine, turn off the climate control

driving it again. Severe engine damage can result from
an overheated engine. See “Engine Overheating”
in
the Index.

when the engine coolant becomes hotter than the normal
operating temperature.
To avoid added strain on a hot
engine, the
air conditioning compressor is automatically
turned
off so that air conditioned air is not delivered. If
