Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel (see
ªFuelº in the Index). Poor fuel quality will cause your
engine not to run as efficiently as designed. You may
notice this as stalling after start
-up, stalling when you
put the vehicle into gear, misfiring, hesitation on
acceleration or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)
This will be detected by the system and cause the light
to turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at least one
full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn off,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools to fix any mechanical or electrical
problems that may have developed.
Engine Oil Pressure Gage
The engine oil pressure
gage shows the engine oil
pressure in psi (pounds per
square inch) or kPa
(kilopascals) when the
engine is running.
Oil pressure should be 20 to 80 psi (140 to 550 kPa).
(In certain situations such as long, extended idles on hot
days, it could read as low as 6 psi (40 kPa) and still be
considered normal.) It may vary with engine speed,
outside temperature and oil viscosity, but readings above
the shaded area show the normal operating range.
Readings in the shaded area tell you that the engine is
low on oil, or that you might have some other oil
problem. See ªEngine Oilº in the Index.
The engine oil pressure can also be displayed using the
GAGES button on the Driver Information Center (DIC).
See ªDriver Information Centerº in the Index.

CAUTION:
Don't keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches fire. You or others could be burned.
Check your oil as soon as possible and have your
vehicle serviced.
NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.
Security Light
This light comes on to
remind you to arm your
theft
-deterrent system. If it
comes on and stays on when
your ignition is on, there
may be a problem with your
theft
-deterrent system.
See ªUniversal Theft
-Deterrentº and ªPASS-Key
Systemº in the Index.
Check Gages Warning Light
This light will come on
briefly when you are
starting the engine. If the
light comes on and stays on
while you are driving, check
your gages to see if they are
in the warning areas.

2-87
This light can come on for the following reasons:

Low Oil Pressure

High Coolant Temperature

High or Low Battery Voltage

Low Fuel Level
Fuel Gage
Your fuel gage tells you
about how much fuel you
have left when the ignition
is on.
When the needle approaches the red zone, RESERVE
FUEL will appear on the Driver Information Center
(DIC) display. When the needle approaches the
ªE,º LOW FUEL will appear on the display. At this
time, you still have a little fuel left, but you should get
more soon.Press RESET to acknowledge a DIC message(s).
Pressing RESET will also turn off a DIC message but
the LOW FUEL message will come on again in 10
minutes if you have not added fuel to the vehicle.
Here are four things that some owners ask about. All
these things 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 FULL (F).

It takes more (or less) fuel to fill up than the gage
reads. For example, the gage reads half full, but it
took more (or less) than half of the tank's capacity to
fill it.

The gage pointer may move while cornering, braking
or speeding up.

The gage may not indicate EMPTY (E) when the
ignition is turned off.

The information may be displayed in English or metric
units and appears as an image focused out toward the
front of your vehicle. The HUD consists of the
following information:

Speedometer

Turn Signal Indicators

High
-Beam Indicator Symbol

Tachometer

Temperature, Oil and Fuel Gages

Shift Light (Performance SHIFT Light)
This light is used for performance driving to indicate
that the vehicle's best performance level has been
reached to shift the transmission into the next higher
gear. The SHIFT light will display at an engine
speed of about 5,750 rpm, just prior to reaching the
engine fuel cut
-off mode. To better understand the
vehicle's power curves, see ªCapacities and
Specificationsº in the Index.

Check Gages IconThere are five HUD selections that you can choose to
view in the HUD display. By pressing and holding the
PAGE button, you can scroll through these pages in the
following order:

Speed Only

Speed and Gage

When you have chosen the desired HUD display, release
the PAGE button.
Gages can be scrolled through by tapping the PAGE
button (only when a gage is displayed). The gages
shown are:

Oil Pressure

Coolant Temperature

Fuel Level
The selections that you choose will remain in the HUD
display until they are changed.

Driver Information Center (DIC)
The Driver Information Center (DIC) will display
information about how your vehicle is functioning, as well
as warning messages if a system problem is detected. The
DIC display area is located in the instrument cluster below
the speedometer and tachometer, directly above the
steering column.
The following buttons are on the DIC control panel which
is located to the right of the instrument panel cluster.
1 FUEL: Press this button to display fuel information
such as fuel economy and range.
2 GAGES: Use this button to display gage information
like oil pressure and temperature, coolant temperature,
transmission fluid temperature, battery voltage and
front/rear tire pressures.
3 TRIP: Use this button to display your total and trip
miles, the elapsed time function, your average speed and
the engine oil life.
4 OPTIONS: This button allows you to choose personal
options that are available on your vehicle, depending on
the options your vehicle is equipped with, such as
security, door locks, easy entry seats and language.
5 E/M: Use this button to change the display between
English and metric units.
RESET: This button, used along with the other buttons,
will reset system functions and turn off or acknowledge
messages on the Driver Information Center (DIC).
At the top of the DIC control buttons is a light sensor.
Be sure not to block the sensor or your lighting
functions may be disrupted.

The average fuel economy is viewed as a long-term
approximation of your overall driving conditions. If you
press RESET in this mode while you're driving, the
system will begin figuring fuel economy from that point
in time.
Press FUEL again to display instantaneous fuel
economy, such as:

INST. 20.1 MPG or

INST. 5.3 L/100 km
Press FUEL again to display the range, such as:

RANGE 20 MI or

RANGE 32 km
The range calculates the remaining distance you can
drive without refueling. It's based on fuel economy and
the fuel remaining in the tank.
If the range is lower than 30 miles (48 km), the display
will read RANGE LOW.
The fuel economy data used to determine fuel range is
an average of recent driving conditions. As your driving
conditions change, this data is gradually updated.
Resetting the fuel range causes the fuel economy data to
be updated immediately. Press RESET to reset the
fuel range.2 GAGES
The GAGES button allows you to scroll through the
functions listed below when you press it.
Press the GAGE button to display the oil pressure,
such as:

OIL PRESSURE 40 PSI or

OIL PRESSURE 276 kPa

Press the GAGE button again to display the oil
temperature, such as:

OIL TEMP 234 F or

OIL TEMP 112 C
Press the GAGE button again to display the coolant
temperature, such as:

COOLANT TEMP 123 F or

COOLANT TEMP 51 C
Press the GAGE button again to display the transmission
fluid temperature (automatic transmission only),
such as:

TRANS FLUID 123 F or

TRANS FLUID 51 C
Press the GAGE button again to display the battery
voltage, such as:

BATTERY VOLTS 13.5
Press the GAGE button again to display the tire pressure
for the front tires (left and right), such as:

FRONT L34 R33 PSI or

FRONT L234 R228 kPaPress the GAGE button again to display the tire pressure
for the rear tires (left and right), such as:

REAR L34 R33 PSI or

REAR L234 R228 kPa
Note that tire pressure is not available until the vehicle
has reached a speed of 15 mph (24 km/h) or more.
3 TRIP
The TRIP button allows you to scroll through the
functions listed below when you press it.
