To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
3. Plug it into a normal, grounded 110-volt AC outlet.
/1 CAUTION.
Plugging the cord into an ungrounded outlet
codd 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
110-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.
E 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 retailer
in the area where you’ll be parking your
vehicle. The retailer can give you the best advice for that
particular area.

Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel (see
“Fuel” in the Index).
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, misfiring, 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,
have your retailer or qualified service center check the
vehicle. Your retailer has the proper test equipment and
diagnostic tools to fix any mechanical or electrical
problems that may have developed.
Oil Pressure Warning Light
If you have a low engine oil
pressure problem, this light
will stay on after you start
your engine,
or come on
and you will
hear a chime
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.
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 the en-gine is
running. If it doesn’t come on with the ignition on,
you may have a problem with the fuse or bulb. Have
it fixed right away.

Check Oil Light
Don’t keep ariving 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.
I NOTICE:
Damage to your engine from neglected oil
your warranty.
1 problems can be costly and is not covered by
/ OIL
This light will come on
briefly when you start
your vehicle.
If the light comes on and you hear a chime or stays on
after starting your vehicle, your engine oil level should
be checked.
Prior to checking the oil level, be sure your vehicle has
been shut
off for several minutes and is on a level
surface. Check the oil level on your dipstick and bring
it
to the proper level. See “Engine Oil” in the Index.
NOTE: A false CHECK OIL light may be generated
when parking on steep grades.
The oil level monitoring system only checks oil level
during the brief period between key on
and engine
crank.
It does not monitor engine oil level when the
engine is running. Additionally, an oil level check is
only performed if the engine has been turned
off for a
considerable period
of time allowing the oil normally in
circulation to drain back into the oil pan.

Tires: They are vitally important to a safe,
trouble-free trip.
Is the tread good enough for
long-distance driving? Are the tires
all inflated to the
recommended pressure?
Weather Forecasts: What’s the weather outlook
along your route? Should you delay your trip a
short
time to avoid a major storm system?
Maps: Do you have up-to-date maps?

Cooling System
When you decide it’s safe to lift the hood, here’s what
you’ll see:
A Coolant Surge Tank with Pressure Cap
B. Electric Engine Cooling Fans

Ik I
/!II CAUTION:
An electric engine cooling fan under the hood can
start up even when the engine is not runnimg
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,
don’t
do anytlung else until it cools down.

Checking Things Under the Hood
An electric fan under the hood can start up and
injure you even when the engine is not running.
Keep hands, clothing and tools away from any
underhood electric fan.
Things that burn can get on
hot engine parts and
start a fire. These include liquids like gasoline,
oil, coolant, brake fluid, windshield washer and
other fluids, and plastic or rubber. You or others
could be burned. Be careful not
to drop or spill
things that will burn onto a hot engine.
Hood Release
The following sections tell you how to check fluids,
lubricants
and important parts under the hood.
To
open the hood, first pull
the
HOOD release handle
inside the vehicle.

Engine Oil
CHECK
OIL
If the CHECK OIL light
on the instrument panel
comes on, it means you
need to check your engine
oil level right away.
For more information, see “Check Oil Light” in the
Index.
You should check your engine oil level regularly;
this is an added reminder.
It’s a good idea to check your engine
oil every time you
get fuel.
In order to get an accurate reading, the oil must
be warm and the vehicle must be on level ground. The engine
yellow and
fi-ont
of the oil
dipstick is
located on the engine.
Turn off the engine and give the oil a few minutes to
drain back into the oil pan.
If you don’t, the oil dipstick
might not show the actual level.

Checking Engine Oil
Pull out the dipstick and clean it with a paper towel or
cloth, then push it back in all the way. Remove it again,
keeping the tip down, and check the level.
When to Add Engine Oil
If the oil is at or below the ADD line, then you’ll need
to add at least one
quart of oil. But you must use the
right kind.
This part explains what kind of oil to use. For
crankcase capacity, see “Capacities and Specifications”
in the Index.
NOTICE: - . -.
. ~~i ~ - ~~
Don’t add too much oil. If your engine has so
much oil that the oil level gets above the upper
mark that shows the proper operating range,
your engine could be damaged.
