2-22 Starting Your 4.3L V6, 5.0L V8 or
5.7L V8 Engine
1. With your foot off the accelerator pedal, turn your
ignition key to START. When the engine starts, let
go of the key. The idle speed will go down as your
engine gets warm.
NOTICE:
Holding your key in START for longer than
15 seconds at a time will cause your battery to
be drained much sooner. And the excessive heat
can damage your starter motor. Wait about
15 seconds between each try to help avoid
draining your battery or damaging your starter.
2. If it doesn't start within 10 seconds, hold your key
in START for not more than 10 seconds. Then, push
the accelerator pedal all the way down for five more
seconds, unless it starts sooner.3. If your engine still won't start (or starts but then
stops), wait 15 seconds and start over.
When the engine starts, let go of the key and the
accelerator pedal.
NOTICE:
Your engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way
the engine operates. Before adding electrical
equipment, check with your dealer. If you don't,
your engine might not perform properly.

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.Automatic Transmission Operation
There are several different positions for your shift lever.
Your vehicle is equipped with an automatic
transmission, and it features an electronic shift position
indicator within the instrument cluster. This display
must be powered anytime the shift lever is capable of
being moved out of the PARK (P) position. This means
that if your key is in OFF, but not locked, there will be a
small current drain on your battery which could
discharge your battery over a period of time. If you have
a need to leave your key in the ignition in OFF for an
extended period for any reason, it is recommended that
you disconnect the battery cable from the battery to
prevent discharging your battery.

You can use the DOME OVERRIDE button, located
below the headlamp knob, to set the dome lamps to
automatically come on when a door is open, or to
remain off.
If the DOME OVERRIDE button is pushed in, the dome
lamps will not come on.
If the DOME OVERRIDE button is out, your interior
lamps will work as usual.
If the button is pressed in, the interior lamps will not
come on when any of the vehicle's doors are opened.
This feature is helpful when you want to leave your
door(s) open for an extended period of time and do not
want to run the battery down. The button is located next
to the lamp switch.Reading Lamps (Option)
If your vehicle has reading lamps, press the button next
to the lamp to turn the lamp on or off.

Accessory Power Outlet
You can plug accessory electrical equipment into an
accessory power outlet. Just pull on the outlet cover
to remove it and follow the proper installation
instructions that are included with any electrical
equipment that you install.
The accessory power outlet is located on the passenger's
side of the front storage compartment.
These circuits are protected by a fuse and have
maximum current levels.Certain power accessory plugs may not be compatible to
the power accessory outlet and could result in blown
vehicle or adapter fuses. If you experience a problem,
see your dealer for additional information on the power
accessory plugs.
NOTICE:
When using the accessory power outlet,
maximum electrical load must not exceed
25 amps. Always turn off any electrical
equipment when not in use. Leaving electrical
equipment on for extended periods will drain
your battery.

CAUTION:
If the air bag readiness light stays on after you
start your vehicle, it means the air bag system
may not be working properly. The air bags in
your vehicle may not inflate in a crash, or they
could even inflate without a crash. To help avoid
injury to yourself or others, have your vehicle
serviced right away if the air bag readiness light
stays on after you start your vehicle.
The air bag readiness light should flash for a few
seconds when you turn the ignition key to RUN. If the
light doesn't come on then, have it fixed so it will be
ready to warn you if there is a problem.
Charging System Light
This light should come on
briefly when you turn on the
ignition, before starting the
engine, as a check to show
you it is working.
After the engine starts, the light should go out. If it stays
on or comes on while you are driving, you may have a
problem with your charging system. It could indicate a
problem with the generator drive belt, or some other
charging system problem. Have it checked right away.
Driving while this light is on could drain your battery.
If you must drive a short distance with this light on, it
helps to turn off all your accessories, such as the radio
and air conditioner.

2-57 Voltmeter
When your engine is not
running, but the ignition is
on (in the RUN position),
this gage shows your
battery's state of charge in
DC volts.
When the engine is running, the gage shows the
condition of the charging system. Readings between
the low and high warning zones indicate the normal
operating range.
Readings in the low warning zone may occur when a
large number of electrical accessories are operating in
the vehicle and the engine is left at an idle for an
extended period. This condition is normal since the
charging system is not able to provide full power at
engine idle. As engine speeds are increased, this
condition should correct itself as higher engine speeds
allow the charging system to create maximum power.You can only drive for a short time with the reading in
either warning zone. If you must drive, turn off all
unnecessary accessories.
Readings in either warning zone indicate a possible
problem in the electrical system. Have the vehicle
serviced as soon as possible.
Brake System Warning Light
When the ignition is on, the brake system warning light
will come on when you set your parking brake. The light
will stay on if your parking brake doesn't release fully.
If it stays on after your parking brake is fully released, it
means you have a brake problem.
Your vehicle's hydraulic brake system is divided into
two parts. If one part isn't working, the other part can
still work and stop you. For good braking, though, you
need both parts working well.
If the warning light comes on, there could be a brake
problem. Have your brake system inspected right away.

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.

If this light comes on or flashes while you are driving,
two things may happen.
First, you won't notice any difference in engine
performance, but your tail pipe emissions may increase.
Second, your engine may not run properly or may stall
without warning. If either of these things happen, drive
or tow your vehicle to your dealer for service.
This light should come on when the ignition is on, but
the engine is not running, as a check to show you it is
working. If it does not come on at all, have it repaired.

4-29
Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little faster
than just idle. That is, push the accelerator slightly.
This uses less fuel for the heat that you get and it keeps
the battery (or batteries) charged. You will need a
well
-charged battery (or batteries) to restart the vehicle,
and possibly for signaling later on with your headlamps.
Let the heater run for a while.
If you have a diesel engine, you may have to run it at a
higher speed to get enough heat. Then, shut the engine
off and close the window almost all the way to preserve
the heat. Start the engine again and repeat this only
when you feel really uncomfortable from the cold. But
do it as little as possible. Preserve the fuel as long as you
can. To help keep warm, you can get out of the vehicle
and do some fairly vigorous exercises every half hour or
so until help comes.
Recreational Vehicle Towing
Your vehicle was not designed to be towed with all four
wheels on the ground. If your vehicle must be towed,
see ªTowing Your Vehicleº in the Index.
NOTICE:
Towing your vehicle with all four wheels on the
ground will damage drivetrain components.
