Vehicle Damage Warnings
Also, in this book you will find these notices:
Notice:These mean there is something that could
damage your vehicle.
A notice will tell you about something that can damage
your vehicle. Many times, this damage would not be
covered by your warranty, and it could be costly. But the
notice will tell you what to do to help avoid the
damage.
When you read other manuals, you might see CAUTION
and NOTICE warnings in different colors or in different
words.
You’ll also see warning labels on your vehicle. They use
the same words, CAUTION or NOTICE.
Vehicle Symbols
Your vehicle has components and labels that use
symbols instead of text. Symbols, used on your vehicle,
are shown along with the text describing the operation
or information relating to a specific component, control,
message, gage or indicator.
If you need help figuring out a specific name of a
component, gage or indicator, reference the following
topics:
•Seats and Restraint Systems in Section 1
•Features and Controls in Section 2
•Instrument Panel Overview in Section 3
•Climate Controls in Section 3
•Warning Lights, Gages and Indicators in Section 3
•Audio System(s) in Section 3
•Engine Compartment Overview in Section 5

Lockout Protection
Lockout protection is intended to provide additional
security and convenience. While any door is open and
the key is in the ignition, the doors cannot be locked
by using the power door locks.
To override this feature, while the key is in the ignition
and any door is open, press and hold down the
power door lock switch for three seconds.
This feature cannot guarantee that you will never be
locked out of your vehicle. If the key is not in the ignition,
or if you use the manual door lock or the remote
keyless entry transmitter, you could still lock your key
inside your vehicle. Always remember to take your
key with you.
Leaving Your Vehicle
If you are leaving your 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. When closing the trunk
lid, push the truck lid in the center to ensure that the lock
fully latches.
{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 “Climate Control
System” in the Index.
If you have air outlets on or under the
instrument panel, open them all the way.
See “Engine Exhaust” in the Index.
2-11

Running Your Engine While You
Are Parked
It is better not to park with the engine running. But if
you ever have to, here are some things to know.
{CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust into
your vehicle. See the earlier Caution under
Engine Exhaust on page 2-27.
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even if
the climate control fan is at the highest setting.
One place this can happen is a garage.
Exhaust — with CO — can come in easily.
NEVER park in a garage with the engine
running.
Another closed-in place can be a blizzard. See
Winter Driving on page 4-23.
{CAUTION:
It can be dangerous to get out of your vehicle
if the shift lever is not fully in PARK (P) with
the parking brake rmly set. Your vehicle can
roll. Do not leave your vehicle when the engine
is running unless you have to. If you have left
the engine running, the vehicle can move
suddenly. You or others could be injured. To
be sure your vehicle will not move, even when
you are on fairly level ground, always set your
parking brake and move the shift lever to
PARK (P).
Follow the proper steps to be sure your vehicle will not
move. SeeShifting Into Park (P) on page 2-24.
If you are parking on a hill and if you are pulling a
trailer, also seeTowing a Trailer on page 4-38.

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, turn the right knob to
select one of the following:
H(Vent):This mode directs air to the instrument
panel outlets.
)(Bi-Level):This mode directs half of the air to the
instrument panel outlets, and then directs most of
the remaining air to the floor outlets. Some air may be
directed toward the side windows.
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.
3-18

Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
(moisture) condensing on the cool window glass. This
can be minimized if the climate control system is used
properly. There are two modes to choose from to clear
fog or frost from your windshield. Use the defog mode to
clear the windows of fog or moisture and warm the
passengers. Use the defrost mode to remove fog or frost
from the windshield more quickly.
Turn the right knob to select the defog or defrost mode.
-(Defog):This mode directs half of the air to the
windshield and half to the floor outlets with a small
amount directed to the side windows. When you select
this mode, the system turns off recirculation
automatically and runs the air-conditioning compressor
unless the outside temperature is at or below freezing.
The recirculation mode cannot be selected while in
the defog mode. Do not drive the vehicle until all the
windows are clear.
1(Defrost):This mode directs most of the air to the
windshield with some air directed to the floor vents.
In this mode, the system will automatically force outside
air into your vehicle and run the air-conditioning
compressor. Recirculation cannot be selected while in
the defrost mode.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
defogger on or off. An indicator light in the button
will come on to let your know that the rear window
defogger is activated. Be sure to clear as much snow
from the rear window as possible.
The rear window defogger will turn off approximately
10 minutes after the button is pressed. If turned on
again, the defogger will only run for approximately
five minutes before turning off. The defogger can also
be turned off by pressing the button again or by turning
off the engine.
Notice:Don’t use anything sharp on the inside of
the rear window. If you do, you could cut or damage
the warming grid, and the repairs wouldn’t be
covered by your warranty. Do not attach a temporary
vehicle license, tape, a decal or anything similar
to the defogger grid.
3-20

Treadwear
The treadwear grade is a comparative rating based on
the wear rate of the tire when tested under controlled
conditions on a specified government test course.
For example, a tire graded 150 would wear one and
a half (1.5) times as well on the government course as
a tire graded 100. The relative performance of tires
depends upon the actual conditions of their use,
however, and may depart significantly from the norm
due to variations in driving habits, service practices and
differences in road characteristics and climate.
Traction – AA, A, B, C
The traction grades, from highest to lowest, are AA, A,
B, and C. Those grades represent the tire’s ability
to stop on wet pavement as measured under controlled
conditions on specified government test surfaces of
asphalt and concrete. A tire marked C may have poor
traction performance. Warning: The traction grade
assigned to this tire is based on straight-ahead braking
traction tests, and does not include acceleration,
cornering, hydroplaning, or peak traction characteristics.
Temperature – A, B, C
The temperature grades are A (the highest), B, and C,
representing the tire’s resistance to the generation
of heat and its ability to dissipate heat when tested
under controlled conditions on a specified indoor
laboratory test wheel. Sustained high temperature can
cause the material of the tire to degenerate and
reduce tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds to a
level of performance which all passenger car tires must
meet under the Federal Motor Vehicle Safety Standard
No. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the
minimum required by law.
Warning: The temperature grade for this tire is
established for a tire that is properly inflated and not
overloaded. Excessive speed, underinflation, or
excessive loading, either separately or in combination,
can cause heat buildup and possible tire failure.
