2-31 To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The cord is attached to the outside of the underhood
fuse box.
3. Plug it into a normal, grounded 110
-volt AC outlet.
CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the wrong
kind of extension cord could overheat and cause
a fire. You could be seriously injured. Plug the
cord into a properly grounded three
-prong
11 0
-volt AC outlet. If the cord won't reach,
use a heavy
-duty three-prong extension cord
rated for at least 15 amps.
4. Before starting the engine, be sure to unplug
and store the cord as it was before to keep it away
from moving engine parts. If you don't, it could
be damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead of
trying to list everything here, we ask that you contact
your dealer in the area where you'll be parking your
vehicle. The dealer can give you the best advice for that
particular area.

2-79 Speedometer and Odometer
Your speedometer lets you see your speed in both miles
per hour (mph) and kilometers per hour (km/h). Your
odometer shows how far your vehicle has been driven,
in either miles (used in the United States) or kilometers
(used in Canada).
You may wonder what happens if your vehicle needs
a new odometer installed. If possible, the new one has
to be set to the same reading the old one had. If it
can't be, then it's set at zero, but a label on the driver's
door must show the old reading and when the new one
was installed.Trip Odometer
The trip odometer can tell you how far your car has been
driven since you last set the trip odometer to zero.
To set the trip odometer to zero, press the TRIP
OIL/RESET knob on the instrument panel cluster.

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
SERVICE ENGINE SOON or 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, see your dealer or qualified service center
to prepare the vehicle for inspection.
Oil Pressure Gage
3800 V6 Engine 5.7L V8 Engine
This gage tells you if there could be a problem
with your engine oil pressure. The gage shows the
engine oil pressure in psi (pounds per square inch)
or kPa (kilopascals) when the engine is running.
Page 146 of 357
2-89
On the 3800 V6 engine, the oil pressure should be
20 to 120 psi (140 to 827 kPa). On the 5.7L V8 engine,
oil pressure should be 20 to 80 psi (140 to 550 kPa).
In certain situations such as long, extended idles on hot
days, it could read as low as 6 psi (40 kPa) and still
be considered normal. It may vary with engine speed,
outside temperature and oil viscosity, but readings above
the red area show the normal operating range. Readings
in the red area tell you that the engine is low on oil,
or that you might have some other oil problem.
See ªEngine Oilº in the Index.
CAUTION:
Don't keep driving if the oil pressure is low. If you
do, your engine can become so hot that it catches fire.
You or others could be burned. Check your oil as
soon as possible and have your vehicle serviced.
NOTICE:
Damage to your engine from neglected oil problems
can be costly and is not covered by your warranty.

2-90 Low Oil Light
This warning light
should come on briefly
while you are starting your
engine. If the light doesn't
come on, have it repaired.
If the light stays on after starting your engine, your
engine oil level may be too low. You may need to add
oil. See ªEngine Oilº in the Index.
NOTICE:
The oil level monitoring system only checks the
oil level when you are starting your engine. It
does not keep monitoring the level once the
engine is running. Also, the oil level check only
works when the engine has been turned off long
enough for the oil to drain back into the oil pan.
Oil Change Light
This OIL CHANGE light
should come on briefly as
a bulb check when you
start the engine. If the OIL
CHANGE light doesn't
come on, have it serviced.
If the OIL CHANGE light comes on and stays on for
60 seconds after you start the engine, have the oil changed.
For additional information, see ªEngine Oil, When to
Changeº in the Index. After changing the engine oil, the
system must be reset. See ªHow to Reset the Oil Change
Lightº in the Index.
