This can happen if you have recently replaced the battery
or if the battery has run down. The diagnostic system is
designed to evaluate critical emission control systems
during normal driving. This can 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 dealer/retailer can prepare the vehicle for
inspection.
Oil Pressure Light
If your vehicle has low
engine oil pressure, this
light will stay on after
you start your engine,
or come on when you
are driving.
This indicates that your engine is not receiving enough
oil. The engine could be low on oil, or could have
some other oil problem. Have it fixed immediately
by your dealer/retailer.The oil light could also come on in three other situations:
•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. The light will go out when you turn the
ignition on. If it does not come on with the ignition
on, you may have a problem with the fuse or bulb.
Have it fixed right away.
•If you make a hard stop, the light may come on for a
moment. This is normal.
{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.
Notice:Lack of proper engine oil maintenance
may damage the engine. The repairs would not
be covered by your warranty. Always follow
the maintenance schedule in this manual for
changing engine oil.

Before Leaving on a Long Trip
To prepare your vehicle for a long trip, consider having
it serviced by your dealer/retailer before departing.
Things to check on your own include:
•Windshield Washer Fluid:Reservoir full?
Windows clean — inside and outside?
•Wiper Blades:In good shape?
•Fuel, Engine Oil, Other Fluids:All levels checked?
•Lamps:Do they all work and are lenses clean?
•Tires:Are treads good? Are tires inflated to
recommended pressure?
•Weather and Maps:Safe to travel?
Have up-to-date maps?
Highway Hypnosis
Always be alert and pay attention to your surroundings
while driving. If you become tired or sleepy, find a
safe place to park your vehicle and rest.
Other driving tips include:
•Keep the vehicle well ventilated.
•Keep interior temperature cool.
•Keep your eyes moving — scan the road ahead
and to the sides.
•Check the rearview mirror and vehicle
instruments often.
Hill and Mountain Roads
Driving on steep hills or through mountains is different
than driving on flat or rolling terrain. Tips for driving
in these conditions include:
•Keep your vehicle serviced and in good shape.
•Check all fluid levels and brakes, tires, cooling
system, and transmission.
•Going down steep or long hills, shift to a lower gear.
{CAUTION:
If you do not shift down, the brakes could
get so hot that they would not work well.
You would then have poor braking or even
none going down a hill. You could crash.
Shift down to let the engine assist the brakes
on a steep downhill slope.

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 3-39.
For hatchbacks, the oil pressure light is on the
Secondary Information Center (SIC). SeeOil Pressure
Light on page 3-52. You should check the engine
oil level regularly; this is an added reminder.

{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 the engine
without coolant is not covered by the warranty.
