Base / Midline Instrument Cluster Descriptions
1. Tachometer
• Indicates the engine speed in revolutions per minute
(RPM x 1000).
2. Voltmeter
• When the vehicle is in the RUN state, the gauge indi -
cates the electrical system voltage. The pointer should
stay within the normal range if the battery is charged.
If the pointer moves to either extreme left or right and
remains there during normal driving, the electrical
system should be serviced.
3. Instrument Cluster Display
• When the appropriate conditions exist, this display
shows the instrument cluster display messages. Refer
to “Instrument Cluster Display” in “Getting To Know
Your Instrument Panel” for further information. 4. Oil Pressure Gauge
• The pointer should always indicate the oil pressure
when the engine is running. A continuous high or low
reading under normal driving conditions may indicate
a lubrication system malfunction. Immediate service
should be obtained from an authorized dealer.
NOTE:
In vehicles equipped with Stop/Start, an oil pressure indica -
tion of zero is normal during an Autostop.
5. Speedometer
• Indicates vehicle speed.

GETTING TO KNOW YOUR INSTRUMENT PANEL 125
6. Fuel Gauge
• The pointer shows the level of fuel in the fuel tank
when the ignition is in the ON/RUN position.
• The fuel pump symbol points to the side of the
vehicle where the fuel door is located.
7. Temperature Gauge
• The gauge pointer shows engine coolant temperature.
The pointer positioned within the normal range indi -
cates that the engine cooling system is operating satis -
factorily.
• The gauge pointer will likely indicate a higher tempera -
ture 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. 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 “Servicing And Maintenance.” Follow the
warnings under the Cooling System Pressure Cap
paragraph.
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. 3

— Vehicle Security Warning Light — If Equipped
This light will flash at a fast rate for approximately 15
seconds when the vehicle security alarm is arming, and then
will flash slowly until the vehicle is disarmed.
— Engine Coolant Temperature Warning Light
This warning light warns of an overheated engine condition.
If the engine coolant temperature is too high, this indicator
will illuminate and a single chime will sound. If the tempera -
ture reaches the upper limit, a continuous chime will sound
for four minutes or until the engine is able to cool: whichever
comes first.
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.
Refer to “If Your Engine Overheats” in “In Case Of Emer -
gency” for further information. — Battery Charge Warning Light
This warning light will illuminate when the battery is not
charging properly. If it stays on while the engine is running,
there may be a malfunction with the charging system.
Contact an authorized dealer as soon as possible.
This indicates a possible problem with the electrical system
or a related component.
— Oil Pressure Warning Light
This warning light will illuminate to indicate low engine oil
pressure. If the light turns on while driving, stop the vehicle,
shut off the engine as soon as possible, and contact an autho -
rized dealer. 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.
— Oil Temperature Warning Light
This warning light will illuminate to indicate the engine oil
temperature is high. If the light turns on while driving, stop
the vehicle and shut off the engine as soon as possible. Wait
for oil temperature to return to normal levels.

GETTING TO KNOW YOUR INSTRUMENT PANEL 149
— Electronic Throttle Control (ETC) Warning Light
This warning light will illuminate to indicate a problem with
the Electronic Throttle Control (ETC) system. If a problem is
detected while the vehicle is running, the light will either
stay on or flash depending on the nature of the problem.
Cycle the ignition 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
vehicle running, your vehicle will usually be drivable;
however, see an authorized dealer for service as soon as
possible.
NOTE:
This light may turn on if the accelerator and brake pedals are
pressed at the same time.
If the light continues to flash when the vehicle 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 placed in the ON/RUN or
ACC/ON/RUN position 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. — Trailer Brake Disconnected Warning Light
This warning light will illuminate when the Trailer Brake has
been disconnected.
— Transmission Temperature Warning Light — If
Equipped
This warning light will illuminate to warn of a high transmis -
sion fluid temperature. This may occur with strenuous usage
such as trailer towing. If this light turns on, stop the vehicle
and run the engine at idle or slightly faster, with the trans -
mission in PARK or NEUTRAL, until the light turns off.
Once the light turns off, you may continue to drive normally.
WARNING!
If you continue operating the vehicle when the
Transmission Temperature Warning Light is illuminated
you could cause the fluid to boil over, come in contact
with hot engine or exhaust components and cause a fire.
CAUTION!
Continuous driving with the Transmission Temperature
Warning Light illuminated will eventually cause severe
transmission damage or transmission failure. 3
