Your vehicle has an engine coolant temperature
gage. With the ignition turned to ON, this gage
shows the engine coolant temperature.
If the gage pointer moves into the red area, your
engine is too hot. It means that your engine
coolant has overheated.
If you have been operating your vehicle under
normal driving conditions, you should pull off the
road, stop your vehicle and turn off the engine
as soon as possible.
SeeEngine Overheating on page 290.
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 acceptablelevels 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:Modi cations made to the engine,
transaxle, exhaust, intake, or fuel system
of your vehicle or replacement tires that do not
match your vehicle’s original tires can affect
your vehicle’s emission controls and may
cause this light to come on. Modi cations 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 264.

If the engine oil
pressure light comes
on, check the engine oil
level right away.
The oil pressure light is on the instrument panel
cluster for sedans. SeeOil Pressure Light on
page 169. For hatchbacks, the oil pressure light is
on the Secondary Information Center (SIC).
SeeOil Pressure Light on page 184. You should
check the engine oil level regularly; this is an
added reminder.

Checking Coolant
The engine coolant surge tank is located in the rear
of the engine compartment on the driver’s side of
the vehicle. SeeEngine Compartment Overview on
page 276for more information on location.
{CAUTION:
Turning the surge tank pressure cap when
the engine and radiator are hot can allow
steam and scalding liquids to blow out
and burn you badly. Never turn the surge
tank pressure cap — even a little — when
the engine and radiator are hot.
To check the engine coolant, the vehicle must be
on a level surface. When your engine is cold,
the coolant level should be between the
Maximum (A) and Minimum (B) marks on the
coolant surge tank. The level rises at engine
operation temperature and drops again when the
engine cools down.

{CAUTION:
An electric engine cooling fan under the
hood can start up even when the engine
is not running and can injure you. Keep
hands, clothing, and tools away from any
underhood electric fan.
If the coolant inside the coolant surge tank is
boiling, do not do anything else until it cools down.
To check the engine coolant, the vehicle should
be parked on a level surface. Make sure that
the air conditioning is turned off.
The coolant level should be between the Minimum
and Maximum marks on the coolant surge tank
when the engine is cool. If it is not, you may have
a leak at the pressure cap or in the radiator
hoses, heater hoses, radiator, water pump, or
somewhere else in the cooling system.
{CAUTION:
Heater and radiator hoses, and other
engine parts, can be very hot. Do not
touch them. If you do, you can be burned.
Do not run the engine if there is a leak. If
you run the engine, it could lose all
coolant. That could cause an engine re,
and you could be burned. Get any leak
xed before you drive the vehicle.
If there seems to be no leak, with the engine on,
check to see if the electric engine cooling fan
is running. If the engine is overheating, the
fan should be running. If it is not, your vehicle
needs service.
Notice:Engine damage from running your
engine without coolant is not covered by your
warranty.
