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 may be equipped with 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 in the Index:
“Engine Compartment Overview’’
“Instrument Panel Overview”
0 “Climate Controls”
“Audio Systems”
Also see
Warning Lights, Gages and Indicators on
page 3-23.

Lockout Protection
Lockout protection is intended to provide enhanced
security and convenience. This feature prevents a driver
who has left the keys in the ignition from locking the
doors, using the power door locks while any door
is open.
To override this feature, when 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 you don’t leave the keys in
the ignition, or
if you use the manual door lock or the
remote keyless entry transmitter, you could still lock your
keys inside your vehicle. Always remember to take
your keys 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

Engine Exhaust
Engine exhaust can kill. It contains the gas
carbon monoxide (CO), which you can’t see
or smell.
It can cause unconsciousness and
death.
You might have exhaust coming in if:
Your exhaust system sounds strange or
Your vehicle gets rusty underneath.
Your vehicle was damaged in a collision.
Your vehicle was damaged when driving
over high points on the road or over road
debris. different.
Repairs weren’t done correctly.
Your vehicle or exhaust system had been
modified improperly.
If you ever suspect exhaust
is coming into
your vehicle:
Drive it only with all the windows down to
Have your vehicle fixed immediately.

CO; and
Running Your Engine While You
Are Parked
It’s better not to park with the engine running. But if you
ever have to, here are some things
to know.
Idling the engine with the climate control
system
off could allow dangerous exhaust into
your vehicle. See the earlier Caution under
“Engine Exhaust.”
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even
if the 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” in the Index.

Climate Controls
Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle.
Operation
Io change the current mode, select one of the following:
2 (Vent): This mode directs air to the instrument
panel outlets.
+2 (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.
(Floor): This mode directs most of the air to the
floor outlets with some air directed to the side windows.
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.
@? (Fan): Turn the left knob clockwise or
counterclockwise to increase or decrease the fan speed.
a (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. The
outside air mode can be used with all modes, but
it cannot be used with the recirculation mode.
(Recirculation): This mode keeps outside air from
coming in the vehicle. It can be used
to prevent outside
cool the air inside your vehicle more quickly. Press this
button to turn the recirculation mode on or
off. The
air-conditioning compressor will come on. The
recirculation mode cannot be used with the outside air
mode. Recirculation is not available when
in the defog or
defrost modes or when the fan
is off.

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.
Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned and balanced
carefully at the factory
to give you the longest tire life
and best overall performance.
Scheduled wheel alignment and wheel balancing are not needed. However,
if you notice unusual tire wear or
your vehicle pulling one way
or the other, the alignment
may need to be reset. If you notice your vehicle
vibrating when driving on a smooth road, your wheels
may need to be rebalanced.
