Engine Coolant Temperature
Warning Light
The engine coolant
temperature warning
light will come on when
the engine has
overheated.
If this happens you should pull over and seeEngine
Overheating on page 309for more information.
Notice:Driving with the engine coolant
temperature warning light on could cause your
vehicle to overheat. SeeEngine Overheating
on page 309. Your vehicle could be damaged,
and it might not be covered by your warranty.
Never drive with the engine coolant
temperature warning light on.
This light will come on and ash when the
temperature of the automatic transaxle uid is too
high. If this happens you should pull over, shift
into PARK (P) and let the engine idle until the light
goes out.
This light will also come on briey when starting your
vehicle. If it does not, have your vehicle serviced.
Low Coolant Warning Light
This light comes on
briey when you turn
your ignition on.
If this light comes on and stays on, the coolant
level in your vehicle is low. If the light is on along
with an overheat warning, you may have a
serious overheating problem.
Notice:Driving with the low coolant warning
light on could cause your vehicle to overheat.
See “Engine Overheating” underEngine
Coolant on page 306. Your vehicle could be
damaged and the damages might not be
covered by your warranty.
SeeEngine Coolant on page 306for information
on what to do. Your vehicle should be serviced as
soon as possible.

Malfunction Indicator Lamp
Check Engine Light
Your vehicle has a
computer which
monitors operation of
the fuel, ignition,
and emission control
systems.
This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended
to assure that emissions are at acceptable
levels for the life of the vehicle, helping to produce
a cleaner environment. The check engine light
comes on to indicate that there is a problem and
service is required. Malfunctions often will be
indicated by the system before any problem is
apparent. This may prevent more serious damage
to your vehicle. This system is also designed to
assist your service technician in correctly
diagnosing any malfunction.Notice:If you keep driving your vehicle with
this light on, after awhile, the emission controls
might not work as well, your vehicle’s fuel
economy might not be as good, and the engine
might not run as smoothly. This could lead to
costly repairs that might not be covered by your
warranty.
Notice:Modications made to the engine,
transaxle, exhaust, intake, or fuel system
of your vehicle or the replacement of the
original tires with other than those of the same
Tire Performance Criteria (TPC) can affect
your vehicle’s emission controls and may
cause this light to come on. Modications to
these systems could lead to costly repairs not
covered by your warranty. This may also
result in a failure to pass a required Emission
Inspection/Maintenance test. SeeAccessories
and Modifications on page 287.

This light should come on, as a check to show
you it is working, when the ignition is on and the
engine is not running. If the light does not
come on, have it repaired. This light will also
come on during a malfunction in one of two ways:
Light Flashing— A misre condition has
been detected. A misre increases vehicle
emissions and may damage the emission
control system on your vehicle. Diagnosis and
service may be required.
Light On Steady— An emission control
system malfunction has been detected on
your vehicle. Diagnosis and service may be
required.
If the Light Is Flashing
The following may prevent more serious damage
to your vehicle:
Reducing vehicle speed
Avoiding hard accelerations
Avoiding steep uphill grades
If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possibleIf the light stops ashing and remains on steady,
see “If the Light Is On Steady” following.
If the light continues to ash, when it is safe to do
so, stop the vehicle. Find a safe place to park
your vehicle. Turn the key off, wait at least
10 seconds and restart the engine. If the light
remains on steady, see “If the Light Is On Steady”
following. If the light is still ashing, follow the
previous steps, and see your retailer for service as
soon as possible.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully
install the cap. SeeFilling the Tank on page 292.
The diagnostic system can determine if the
fuel cap has been left off or improperly installed.
A loose or missing fuel cap will allow fuel to
evaporate into the atmosphere. A few driving trips
with the cap properly installed should turn the
light off.

Did you just drive through a deep puddle of water?
If so, your electrical system may be wet.
The condition will usually be corrected when the
electrical system dries out. A few driving trips
should turn the light off.
Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel.
SeeGasoline Octane on page 289. 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, misring, 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, your retailer can check the vehicle.
Your retailer has the proper test equipment and
diagnostic tools to x any mechanical or electrical
problems that may have developed.Emissions Inspection and
Maintenance Programs
Some state/provincial and local governments have
or may begin programs to inspect the emission
control equipment on your vehicle. Failure to pass
this inspection could prevent you from getting a
vehicle registration.
Here are some things you need to know in order
to help your vehicle pass an inspection:
Your vehicle will not pass this inspection if the
check engine light is on or not working properly.
Your vehicle will not pass this inspection if
the OBD (on-board diagnostic) system determines
that critical emission control systems have not
been completely diagnosed by the system.
The vehicle would be considered not ready for
inspection. This can happen if you have recently
replaced your battery or if your battery has
run down. The diagnostic system is designed to
evaluate critical emission control systems
during normal driving. This may take several days
of routine driving. If you have done this and
your vehicle still does not pass the inspection for
lack of OBD system readiness, your retailer
can prepare the vehicle for inspection.

Oil Pressure Light
If you have a low
engine oil pressure
problem, this light will
stay on after you
start your engine, or
come on when you
are driving.

enough oil.
The engine could be low on oil, or could have
some other oil problem. Have it xed immediately.
The oil light may also come on when the ignition
is on but the engine is not running, the light
will come on as a test to show you it is working,
but the light will go out when you turn the
ignition to START. If it does not come on with the
ignition on, you may have a problem with the
fuse or bulb. Have it xed right away.{CAUTION:
Do not keep driving if the oil pressure is
low. If you do, your engine can become so
hot that it catches re. You or others could
be burned. Check your oil as soon as
possible and have your vehicle serviced.

Charge/Assist Gage
The CHARGE/ASSIST
gage displays the
charge (current) into
and out of the hybrid
battery.
When the electric motor is performing an
automatic restart of the engine, or when it is
assisting the engine as in a maximum acceleration,
the needle will move to the ASSIST range.
The ASSIST range is on the right side of the gage,
and shows an arrow pointing out of a battery.When the electric motor operates as a generator
to perform regenerative braking while decelerating,
the needle will move to the CHARGE range.
SeeRegenerative Braking on page 121for more
information. The needle will also move into
the CHARGE range if the hybrid control system
deems it is an efficient time to charge the
hybrid battery. The CHARGE range is on the left
side of the gage, and shows an arrow pointing
into a battery.
If the hybrid battery or other hybrid components
are very hot or cold, the CHARGE and ASSIST
functions may be suspended until the component
temperatures are normal.
