Engine Coolant Heater (If Equipped) To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The cord for the engine coolant heater is located on
the driver's side
of the engine compartment and is
attached to the hose for the power steering reservoir.

3. Plug it into a normal, grounded 110-volt AC outlet.
In very cold weather,
0°F (- 18 O C) or colder, the engine
coolant heater can help. You'll get easier starting and
better fuel economy during engine warm-up. Usually,
the coolant heater should be plugged in
a minimum of
four hours prior to starting your vehicle.
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
110-volt
AC outlet. If the cord won't reach, use a
heavy-duty three-prong extension cord rated
for
at least 15 amps.

NOTICE:
Driving with the parking brake on can cause your
rear brakes to overheat. You may have to replace
them, and you could also damage other parts of
your vehicle. Always check to
be sure your parking
brake
is fully released before you drive.
If you are towing a trailer and are parking on any hill,
see “Towing a Trailer” in the Index. That section shows
what to do first to keep the trailer from moving.
Shifting Into PARK (P)
It can be dangerous to get out of your vehicle if
the shift lever is not fully in PARK
(P) with the
parking brake firmly set. Your vehicle can roll.
If
you have left the engine running, the vehicle can
move suddenly. You or others could be injured.
To be sure your vehicle won’t move, even when
you’re on fairly level ground, use the steps that
follow.
If you’re pulling a trailer, see “Towing a
Trailer” in the Index.
1. Hold the brake pedal down with your right foot and
set the parking brake.

Leaving Your Vehicle With the
Engine Running
A CAUTION:
It can be dangerous to leave your vehicle with the
engine running. Your vehicle could move
suddenly if the shift lever is not fully in
PARK (P)
with the parking brake firmly set. And, if you
leave the vehicle with the engine running, it could
overheat and even catch fire. You
or others could
be injured. Don’t leave your vehicle with the
engine running unless you have to.
Torque Lock
If you are parking on a hill and you don’t shift your
transmission into
PARK (P) properly, the weight of the
vehicle may put too much force on the parking pawl in
the transmission. You may find it difficult to pull the
shift lever out of PARK (P). This
is called “torque lock.”
To prevent torque lock, set the parking brake and then
shift into PARK
(P) properly before you leave the
driver’s seat.
To find out how, see “Shifting Into
PARK (P)” in the Index.
When you are ready
to drive, move the shift Tever out of
PARK (P)
before you release the parking brake.
If torque lock does occur, you may need to have another
vehicle push yours a little uphill to take some
of the
pressure from the parking pawl in the transmission,
so
you can pull the shift lever out of PARK (P).

Anti-Lock Brake System Warning Light
ANTI -
LOCK
United States Canada
With
the anti-lock brake system, this light will come on
when you start your engine and may stay on for several
seconds. That’s normal.
If the light stays on, or comes
on when you’re driving,
your vehicle needs service. If the regular brake system
warning light isn’t
on, you still have brakes, but you
don’t have anti-lock brakes. If the regular brake system
warning light is also
on, you don’t have anti-lock brakes
and there’s a problem with your regular brakes. See
“Brake System Warning Light” earlier in this section.
The anti-lock brake system warning light should come
on briefly 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.
Engine Coolant Temperature Gage
This gage shows the engine
gage pointer moves into
the red area your engine is
coolant temperature.
If the
260 too
hot!
It means that your engine coolant has overheated.
If
you have been operating your vehicle under normal
operating conditions,
you should pull off the road, stop
your vehicle, and turn off the engine as soon as possible.
The “Problems on the Road’’ section of this
manual shows what
to do. See “Engine Overheating”
in the Index.

Making Turns
NOTICE:
Making very sharp turns while trailering could cause the trailer to come in contact with the vehicle. Your vehicle could be damaged. Avoid
making very sharp turns while trailering.
When you’re turning with a trailer, make wider turns than
normal.
Do this so your trailer won’t strike soft shoulders,
curbs, road signs, trees or other objects. Avoid jerky or
sudden maneuvers. Signal well
in advance.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have extra
wiring and a heavy-duty turn signal flasher (included in
the optional trailering package).
The arrows on your instrument panel will flash
whenever you signal
a turn or lane change. Properly
hooked up, the trailer lamps will also flash, telling other
drivers you’re about
to turn, change lanes or stop. When towing
a trailer,
the arrows on your instrument
panel
will flash for turns even if the bulbs on the trailer
are burned out. Thus, you may think drivers behind
you are seeing your signal when they are not. It’s
important to check occasionally
to be sure the trailer
bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade. If you don’t shift
down, you might have
to use your brakes so much that
they would get hot and
no longer work well.
On a long uphill grade, shift down and reduce your
speed to around
45 mph (70 km/h) to reduce the
possibility of engine and transmission overheating.
When towing at high altitude on steep uphill grades,
consider the following: Engine coolant will boil at a lower
temperature than at normal altitudes. If you turn your
engine
off immediately after towing at high altitude on
steep uphill grades, your vehicle may show signs similar to
engine overheating.
To avoid this, let the engine run while
parked (preferably
on level ground) with the automatic
transmission
in PARK (P) for a few minutes before turning
the engine off. If you do get
the overheat warning, see
“Engine Overheating” in
the Index.

Rear Towir -
I NOTICE:
Do not tow the vehicle from the rear with loads
approaching rated
GVW as the weight transfer will
cause the front suspension to become overloaded.
NOTICE:
Do not tow with the sling-type equipment or the
rear bumper will be damaged. Use wheel lift
or
car-carrier equipment. Additional ramping may
be required for car-carrier equipment. Use safety
chains and wheel straps.
Towing a vehicle over rough surfaces could
damage a vehicle. To help avoid damage, install
a towing dolly and raise the vehicle until
adequate clearance is obtained between the
ground and/or wheel-lift equipment.
Engine Overheating (Gasoline Engine)
You will find a coolant temperature gage on your vehicle’s
instrument panel.
If you have a diesel engine, you will also
find a low coolant light on your instrument panel.
If your vehicle has a diesel engine, see “Engine
Overheating”
in the Diesel Engine Supplement.
