302 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

1.Fuel Gauge
• The pointer shows the level of fuel in the fuel tank
when the ignition switch is in the ON/RUN position.
• The fuel pump symbol
points to the side of the
vehicle where the fuel filler door is located.
2. Speedometer
• Indicates vehicle speed.
3. Tachometer
• Indicates the engine speed in revolutions per minute
(RPM x 1000).
CAUTION!
Do not operate the engine with the tachometer
pointer in the red area. Engine damage will occur. 4.
Temperature Gauge
• The temperature gauge shows engine coolant tem-
perature. Any reading within the normal range indi-
cates that the engine cooling system is operating
satisfactorily.
• The gauge pointer will likely indicate a higher tem-
perature when driving in hot weather, up mountain
grades, or when towing a trailer. It should not be
allowed to exceed the upper limits of the normal
operating range.
CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge reads
“H” pull over and stop the vehicle. Idle the vehicle
with the air conditioner turned off until the pointer
drops back into the normal range. If the pointer

remains on the “H”, turn the engine off immediately
and call an authorized dealer for service.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer
for service if your vehicle overheats. If you decide to
look under the hood yourself, see “Maintaining Your
Vehicle”. Follow the warnings under the Cooling
System Pressure Cap paragraph.
5. Odometer / Trip Odometer Display Area
• The odometer display shows the total distance the
vehicle has been driven. The trip odometer shows individual trip mileage. Refer to “Odometer/Trip
Odometer/ECO (Fuel Saver Indicator) Button” for
further information.
• U.S. Federal regulations require that upon transfer of
vehicle ownership, the seller certify to the purchaser
the correct mileage that the vehicle has been driven.
If your odometer needs to be repaired or serviced,
the repair technician should leave the odometer
reading the same as it was before the repair or
service. If they cannot do so, then the odometer must
be set at zero, and a sticker must be placed in the
door jamb stating what the mileage was before the
repair or service. It is a good idea for you to make a
record of the odometer reading before the repair/
service, so that you can be sure that it is properly
reset, or that the door jamb sticker is accurate if the
odometer must be reset at zero.

Vehicle Odometer Messages
If the vehicle is equipped with the optional Electronic
Vehicle Information Center (EVIC) in the instrument
cluster, all messages will display in the EVIC. Refer to
“Electronic Vehicle Information Center — If Equipped”
in this section for further information.
When the appropriate conditions exist, the following
odometer messages will display:•ECO
• door
• gATE
• LoW tirE
• HOTOIL
• gASCAP
• noFUSE
• CHAngE OILCAUTION!
Continuous driving with the Transmission Tempera-
ture “HOTOIL” Warning message illuminated will
eventually cause severe transmission damage or
transmission failure.
WARNING!
If the Transmission Temperature “HOTOIL” Warn-
ing message is illuminated and you continue operat-
ing the vehicle, in some circumstances you could
cause the fluid to boil over, come in contact with hot
engine or exhaust components and cause a fire.
6. Software Telltales

Red Telltale Indicator Lights
Charging System Warning Light
Red TelltaleLight What It Means
Charging System Warning Light
This light shows the status of the electrical charging system. If the light stays on or comes
on while driving, turn off some of the vehicle’s nonessential electrical devices or increase
engine speed (if at idle). If the charging system light remains on, it means that the vehicle is
experiencing a problem with the charging system. Obtain SERVICE IMMEDIATELY. See an
authorized dealer.
If jump starting is required, refer to “Jump Starting Procedures” in “What To Do In Emer-
gencies.”4

Oil Pressure Warning Light
Red TelltaleLight What It Means
Oil Pressure Warning Light
This light indicates low engine oil pressure. If the light turns on while driving, stop the ve-
hicle and shut off the engine as soon as possible. A chime will sound when this light turns
on.
Do not operate the vehicle until the cause is corrected. This light does not indicate how
much oil is in the engine. The engine oil level must be checked under the hood.

Coolant Temperature Warning Light
Red TelltaleLight What It Means
Coolant Temperature Warning Light
This light warns of an overheated engine condition. If the light turns on while driving,
safely pull over and stop the vehicle. If the A/C system is on, turn it off. Also, shift the
transmission into NEUTRAL and idle the vehicle. If the temperature reading does not return
to normal, turn the engine off immediately and call for service.
NOTE:
As the coolant temperature gauge approaches
H,this indicator will illuminate and a single
chime will sound. Further overheating will cause the temperature gauge to pass H.In this
case, a continuous chime will sound until the engine is allowed to cool or the 4 minutes du-
ration is expired, whichever come first.

Electronic Throttle Control (ETC) Warning Light
Red TelltaleLight What It Means
Electronic Throttle Control (ETC) Warning Light
This light informs you of a problem with the Electronic Throttle Control (ETC) system. If a
problem is detected while the engine is running, the light will either stay on or flash de-
pending on the nature of the problem. Cycle the ignition key when the vehicle is safely and
completely stopped and the transmission is placed in the PARK position. The light should
turn off. If the light remains on with the engine running, your vehicle will usually be driv-
able; however, see an authorized dealer for service as soon as possible.
If the light continues to flash when the engine is running, immediate service is required and
you may experience reduced performance, an elevated/rough idle, or engine stall and your
vehicle may require towing. The light will come on when the ignition is first turned to ON/
RUN and remain on briefly as a bulb check. If the light does not come on during starting,
have the system checked by an authorized dealer.

Engine Check/Malfunction Indicator Light (MIL)
Yellow TelltaleLight What It Means
Engine Check/Malfunction Indicator Light (MIL)
The Engine Check/Malfunction Indicator Light (MIL) is a part of an Onboard Diagnostic
System called OBD II that monitors engine and automatic transmission control systems. The
light will illuminate when the ignition is in the ON position before engine start. If the bulb
does not come on when turning the key from OFF to ON/RUN, have the condition checked
promptly.
Certain conditions, such as a loose or missing gas cap, poor quality fuel, etc., may illuminate
the light after engine start. The vehicle should be serviced if the light stays on through sev-
eral typical driving styles. In most situations, the vehicle will drive normally and will not
require towing.
When the engine is running, the MIL may flash to alert serious conditions that could lead to
immediate loss of power or severe catalytic converter damage. The vehicle should be ser-
viced as soon as possible if this occurs.
326 UNDERSTANDING YOUR INSTRUMENT PANEL

CAUTION!
Prolonged driving with the Malfunction Indicator
Light (MIL) on could cause damage to the engine
control system. It also could affect fuel economy and
driveability. If the MIL is flashing, severe catalytic
converter damage and power loss will soon occur.
Immediate service is required.
WARNING!
A malfunctioning catalytic converter, as referenced
above, can reach higher temperatures than in normal
operating conditions. This can cause a fire if you drive
slowly or park over flammable substances such as dry
plants, wood, cardboard, etc. This could result in death
or serious injury to the driver, occupants or others.
