Lockout Protection
If your vehicle is equipped with remote keyless entry,
you have lockout protection. This feature stops the
power door locks from locking when the keys are in the
ignition and the door is open.
If the power door lock switch is pressed when a door is
open and the key is in the ignition, all the doors will
lock and the driver's door will unlock.
Leaving Your Vehicle
If you are leaving the vehicle, open your door and set
the locks from the inside. Then get out and close
the door.
Trunk
To unlock the trunk from the outside, insert the key and
turn the trunk lock cylinder or use the remote keyless
entry transmitter if your vehicle has one.
When closing the trunk, close from the center to ensure
it fully latches. Although you may use one hand to
unlock the trunk, it is recommended that two hands on
the upper surface be used to close the trunk.
{CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You can't see or smell
CO. It can cause unconsciousness and even
death. If you must drive with the trunk lid open
or if electrical wiring or other cable
connections must pass through the seal
between the body and the trunk lid:
·Make sure all other windows are shut.
·Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. See ªClimate Control
Systemº in the Index.
·If you have air outlets on or under the
instrument panel, open them all the way.

Accessory Power Outlets
The accessory power outlet can be used to connect
electrical equipment such as a cellular phone or
CB radio.
The accessory power outlet is located on the lower
console on the passenger's side.
To use the outlet, remove the cover. When not in use,
always cover the outlet with the protective cap.
Notice:When using an accessory power outlet,
maximum electrical load must not exceed ®ve amps.
Always turn off any electrical equipment when not
in use. Leaving electrical equipment on for extended
periods will drain your battery.
Certain electrical accessories may not be compatible
with the accessory power outlet and could result
in blown vehicle or adapter fuses. If you experience a
problem, see your dealer for additional information
on the accessory power outlet.
Notice:Adding some electrical equipment to your
vehicle can damage it or keep other things from
working as they should. This wouldn't be covered by
your warranty. Check with your dealer before
adding electrical equipment, and never use anything
that exceeds the amperage rating.When adding electrical equipment, be sure to follow the
installation instructions included with the equipment.
Notice:Power outlets are designed for accessory
plugs only. Do not hang any type of accessory
or accessory bracket from the plug. Improper use of
the power outlet can cause damage not covered
by your warranty.

Climate Controls
Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle.
Operation
To change the current mode, select one of the following:
H(Vent):This mode directs air to the instrument
panel outlets.
)(Bi-Level):This mode directs approximately half of
the air to the instrument panel outlets, and then
directs the remaining air to the ¯oor outlets. Cooler air is
directed to the upper outlets and warmer air to the
¯oor outlets.
6(Floor):This mode directs most of the air to the
¯oor outlets and outboard outlets (for the side windows)
with some air directed to the windshield.
The right knob can also be used to select defrost mode.
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.
In any setting other than off, the fan will run continuously
with the ignition on. The fan must be turned on to run
the air conditioning compressor.
9(Off):To turn the fan off, turn the knob all the way
counterclockwise to the off position.
h(Recirculate):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.
An indicator light will come on in this mode. The
air-conditioning compressor also comes on. Operation in
this mode during periods of high humidity and cool
outside temperatures may result in increased window
fogging. If window fogging is experienced, select
the defrost mode.

Enhanced Traction System
Active Light
When your Enhanced Traction System is limiting wheel
spin, this light will come on. Slippery road conditions
may exist if the Enhanced Traction System active light
comes on, so adjust your driving accordingly.
This light may also come on when the anti-lock brake
system is active.
The light will stay on for a few seconds after the
Enhanced Traction System stops limiting wheel spin.
The Enhanced Traction System active light also comes
on brie¯y when you turn the ignition key to RUN. If
the light doesn't come on then, have it ®xed so it will be
there to tell you when the system is active.
Engine Coolant Temperature Gage
Your vehicle is equipped with one of these gages. With
the ignition in RUN, 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. The CHECK GAGES light should come on
if this condition exists. See
Check Gages Warning
Light on page 3-34for more information. If you have
been operating your vehicle under normal conditions,
you should pull off the road, stop your vehicle and turn
off the engine as soon as possible.

Low Coolant Warning Light
This light comes on brie¯y
when you turn your
ignition on.
If this light comes on and stays on, the coolant level in
your vehicle is low. 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:Damage to your engine from neglected
coolant problems can be costly and is not covered
by your warranty.
See
Engine Coolant on page 5-22for information on
what to do. Your vehicle should be serviced as soon as
possible.
Malfunction Indicator Lamp
Check Engine Light
Your vehicle is equipped with a computer which
monitors operation of the fuel, ignition and emission
control systems.
This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for the
life of the vehicle, helping to produce a cleaner
environment. The CHECK ENGINE light comes on to
indicate that there is a problem and service is required.
Malfunctions often will be indicated by the system
before any problem is apparent. This may prevent more
serious damage to your vehicle. This system is also
designed to assist your service technician in correctly
diagnosing any malfunction.

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 gear
beforeyou 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 transaxle overheating.
Pay attention to the engine coolant gage. If the indicator
is in the red area, turn off the air conditioning to
reduce engine load. See
Engine Overheating on
page 5-25.
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's
how to do it:
1. Apply your regular brakes, but don't shift into
PARK (P) yet. When parking uphill, turn your wheels
away from the curb. When parking downhill, turn
your wheels into the curb.
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 then shift to PARK (P).
5. Release the regular brakes.
4-39

When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
·start your engine,
·shift into a gear, and
·release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the
chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you're
pulling a trailer. SeePart A: Scheduled Maintenance
Services on page 6-4for more on this. Things that are
especially important in trailer operation are automatic
transaxle ¯uid (don't over®ll), engine oil, drive belt,
cooling system and brake system.
Each of these is covered in this manual, and the Index
will help you ®nd them quickly. If you're trailering,
it's a good idea to review this information before you
start your trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. SeeEngine Overheating on
page 5-25.
Towing a Trailer (Manual Transaxle)
Do not tow a trailer if your vehicle is equipped with a
manual transaxle.

Engine Coolant
The cooling system in your vehicle is ®lled with
DEX-COOLžengine coolant. This coolant is designed
to remain in your vehicle for 5 years or 150,000 miles
(240 000 km), whichever occurs ®rst, if you add
only DEX-COOL
žextended life coolant.
The following explains your cooling system and how to
add coolant when it is low. If you have a problem
with engine overheating, see
Engine Overheating on
page 5-25.
A 50/50 mixture of clean, drinkable water and
DEX-COOL
žcoolant will:
·Give freezing protection down to-34ÉF (-37ÉC).
·Give boiling protection up to 265ÉF (129ÉC).
·Protect against rust and corrosion.
·Help keep the proper engine temperature.
·Let the warning lights and gages work as they
should.
Notice:When adding coolant, it is important that
you use only DEX-COOLž(silicate-free) coolant.
If coolant other than DEX-COOLžis added to
the system, premature engine, heater core or
radiator corrosion may result. In addition, the engine
coolant will require change sooner Ð at 30,000 miles
(50,000 km) or 24 months, whichever occurs ®rst.
Damage caused by the use of coolant other
than DEX-COOL
žis not covered by your new vehicle
warranty.
What to Use
Use a mixture of one-halfclean, drinkable waterand
one-half DEX-COOLžcoolant which won't damage
aluminum parts. If you use this coolant mixture,
you don't need to add anything else.
{CAUTION:
Adding only plain water to your cooling
system can be dangerous. Plain water, or
some other liquid such as alcohol, can boil
before the proper coolant mixture will.
CAUTION: (Continued)
5-22

The vehicle must be on a level surface. When your
engine is cold, the coolant level should be at the FULL
COLD mark.
If the low coolant light
comes on and stays on, it
means you're low on
engine coolant. See
Low
Coolant Warning Light
on page 3-30
.
Adding Coolant
If you need more coolant, add the proper DEX-COOLž
coolant mixtureat the surge tank, but only when the
engine is cool. If the surge tank is empty, a special ®ll
procedure is necessary. See
Engine Overheating
on page 5-25for instructions on ªHow to Add Coolant to
the Coolant Surge Tank.º
{CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it will burn if the engine parts are hot
enough. Don't spill coolant on a hot engine.
When replacing the pressure cap, make sure it is
hand-tight.
Coolant Surge Tank Pressure Cap
Notice:Your pressure cap is a pressure-type
cap and must be tightly installed to prevent coolant
loss and possible engine damage from overheating.
See ªCapacities and Speci®cationsº for more
information.
