Section 2 Features and Controls

Engine Coolant Heater
Your vehicle may have this feature. In very cold
weather, 0°F (−18°C) or colder, the engine coolant
heater can provide 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. At temperatures
above 32°F (0°C), use of the coolant heater is not
required.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The engine coolant heater cord is located in
front of the coolant surge tank on the passenger’s
side. SeeEngine Compartment Overview on
page 5-12for more information on location.
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 re. You could be seriously
injured. Plug the cord into a properly grounded
three-prong 110-volt AC outlet. If the cord will
not 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 do not, 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 will be parking
your vehicle. The dealer can give you the best advice
for that particular area.

A(Floor):This mode directs most of the air to the
floor outlets with some air directed to the side window
outlets.
The right knob can also be used to select defog or
defrost modes. Information on defogging and defrosting
can be found later in this section.
9(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the fan speed.
The fan must be on to run the air-conditioning
compressor.
:(Outside Air):Press this button to turn the
outside air mode on or off. When this mode is on,
outside air will circulate throughout your vehicle. When
the button is pressed, an indicator light in the button
will come on to let you know that it is activated.
The outside air mode can be used with all modes, but it
cannot be used with the recirculation mode. Pressing
this button will cancel the recirculation mode.
?(Recirculation):This mode keeps outside air
from coming in the vehicle. It can be used to prevent
outside air and odors from entering your vehicle or
to help heat or cool the air inside your vehicle more
quickly. Press this button to turn the recirculation mode
on or off. When the button is pressed, an indicator
light in the button will come on to let you know that it is
activated. The air-conditioning compressor comeson. The recirculation mode can be used with vent,
bi-level, or floor modes, but it cannot be used with the
defog or defrost modes. Pressing this button will
cancel the outside air mode. When you switch to the
defog or defrost modes the system will automatically
move from recirculation to outside air. When you move
the mode knob back to another mode, the system
will move back into recirculation. When the car is turned
off and back on the system will default to outside air
automatically.
Temperature Control:Turn the center knob clockwise
or counterclockwise to increase or decrease the
temperature inside your vehicle.
When it’s cold outside 0°F (−18°C) or lower, use the
engine coolant heater, if equipped, to provide warmer air
faster to your vehicle. An engine coolant heater warms
the coolant that the engine uses to provide heat to
warm the inside of your vehicle. For more information,
seeEngine Coolant Heater on page 2-18.#A/C (Air Conditioning):Press this button to turn
the air-conditioning system on or off. When A/C is
pressed, an indicator light in the button will come on to
let you know that air conditioning is activated.
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for your vehicle to cool down. It also helps
the system to operate more efficiently.

Engine Coolant Temperature Gage
This gage shows the
engine coolant
temperature.
If the gage pointer moves into the red area, the light
comes on and you hear a chime, your engine is too hot!
It means that your engine coolant has overheated.
If you have been operating your vehicle under normal
driving conditions, you should pull off the road, stop your
vehicle and turn off the engine as soon as possible.
SeeEngine Overheating on page 5-22.
Low Coolant Warning Light
This light comes on briefly
when you turn your ignition
to ON.
If this light comes on and stays on, the coolant level in
your vehicle is low. SeeEngine Coolant on page 5-18.
If the light is on along with an overheat warning,
you may have a serious overheating problem, see
Engine Coolant Temperature Gage on page 3-29.
Notice:If you operate the engine without coolant
or fail to maintain the cooling system properly,
you could damage the engine. The repairs would not
be covered by your warranty. Always follow the
maintenance schedule in this manual for
maintaining your cooling system. SeeCooling
System on page 5-24for more information.
SeeEngine Overheating on page 5-22for information
on what to do. Your vehicle should be serviced as soon
as possible.

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
is important to check occasionally to be sure the trailer
bulbs are still working.
Driving On Grades
Notice:Do not tow on steep continuous grades
exceeding 6 miles (9.6 km). Extended, higher
than normal engine and transaxle temperatures
may result and damage your vehicle. Frequent stops
are very important to allow the engine and transaxle
to cool.
Reduce speed and shift to a lower gearbeforeyou start
down a long or steep downgrade. If you do not shift
down, you might have to use your brakes so much that
they would get hot and no longer work well.
Pay attention to the engine coolant gage. If the indicator
is in the red area, turn off the air conditioning to
reduce engine load. SeeEngine Overheating on
page 5-22.
Parking on Hills
{CAUTION:
You really should not park your vehicle, with a
trailer attached, on a hill. If something goes
wrong, your rig could start to move. People
can be injured, and both your vehicle and the
trailer can be damaged.
But if you ever have to park your rig on a hill, here is
how to do it:
1. Apply your regular brakes, but do not shift into
PARK (P) yet.
2. Have someone place chocks under the trailer
wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then apply your
parking brake and shift into PARK (P).
5. Release the regular brakes.

Checking Things Under
the Hood
{CAUTION:
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.
{CAUTION:
Things that burn can get on hot engine parts
and start a re. These include liquids like fuel,
oil, coolant, brake uid, windshield washer and
other uids, 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
To open the hood, do the following:
1. Pull the hood release
handle located inside
the vehicle to the left of
the parking brake.
