1. Turn off the engine. I
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.
In very cold weather,
0°F (- I 8OC) 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.

3. Plug it into a normal, grounded 1 IO-volt AC outlet.
1 A
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
110-volt
AC outlet. If the cord won’t reach, use a
heavy-duty three-prong extension cord rated for
at least 15 amps.

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 the OFF position, 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 the
OFF position for an extended period for any reason, it is
recommended that
you disconnect the battery cable from
the battery
to prevent discharging your battery.

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 (I ~ - -:
This gage shows the engine
coolant temperature. If the
gage pointer moves into
the red area your engine is
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.

The CHECK GAGES light
will come on briefly when

If
the light comes on and stays on while you are driving,
check your coolant temperature and engine oil pressure

Before using your vehicle’s air conditioning, open the
windows to clear the vehicle
of hot air. This reduces the
time it takes for your vehicle to cool down. Then keep
your windows closed for the air conditioner to work at
its best.
You can use
MAX A/C with the temperature knob in the
blue area when it’s really hot outside and you need to
cool the inside air quickly. MAX A/C lets in only a little
air from the outside.
If you first use MAX A/C, you can then use A/C with
the temperature knob in the blue area, as soon as
the
vehicle has cooled down, so outside air will be going
through your vehicle.
If your vehicle has rear air conditioning, setting
it on LO
may enhance front A/C performance by allowing
trapped refrigerant in rear lines
to circulate.
When the air conditioning, DEFROST or
BLEND is on,
you may notice
a slight increase or decrease in engine
speed, due to compressor operation. This is normal
because the system is designed
to cycle the compressor
on and off
to keep the desired temperature. On
cold days,
use HEATER with the temperature knob
in the red area. Outside air will be brought in through
the floor outlets. The heater works best
if you keep your
windows closed while using it.
If you
use the optional engine coolant heater before
starting your engine, your heating system will produce
warmer air faster to heat the passenger compartment in
cold weather. See “Engine Coolant Heater”
in the Index.
Ventilation Tips
Keep the hood and front air inlet free of ice, snow, or
any other obstruction (such as leaves). The heater
and defroster will work far better, reducing the
chance
of fogging the inside of your windows.
When you enter a vehicle in cold weather, turn the
blower fan to HI for a few moments before driving
off. This helps clear the intake ducts
of snow and
moisture, and reduces the chance of fogging the
inside
of your windows.
0 Keep the air path under the front seats clear of objects.
This helps air to circulate throughout your vehicle.
Your vehicle has air vents in the center and
on the sides
of your instrument panel.

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.
lhrn 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 kdh) 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 tumine
the engine off. If you do get the overheat warning, see
“Engine Overheating”
in the Index.
