CLIMATE CONTROL SYSTEM
Manual heating and air conditioning system
Fan speed control
Controls the volume of
air circulated in the
vehicle.
Temperature control knob
Controls the
temperature of the
airflow inside the
vehicle.
Mode selector control
Controls the direction
of the airflow to the
inside of the vehicle.
The air conditioning compressor will operate in all
modes except VENT and FLR. However, the air
conditioning will only function if the outside
temperature is about 10ÉC (50ÉF) or above.
Since the air conditioner removes considerable
moisture from the air during operation, it is normal
if clear water drips on the ground under the air
conditioner drain while the system is working and
even after you have stopped the vehicle.

Under normal conditions, your vehicle's climate
control system should be left in any position other
than MAX A/C or OFF when the vehicle is parked.
This allows the vehicle to ªbreatheº through the
outside air inlet duct.
²MAX A/C-Uses recirculated air to cool the vehicle.
MAX A/C is noisier than NORM A/C but more
economical and will cool the inside of the vehicle
faster. Airflow will be from the instrument panel
registers. This mode can also be used to reduce
undesirable odors from entering the vehicle.
²NORM A/C-Uses outside air to cool the vehicle. It
is quieter than MAX A/C but not as economical.
Airflow will be from the instrument panel
registers.
²VENT-Distributes outside air through the
instrument panel registers. However, the air will
not be cooled below the outside temperature
because the air conditioning does not operate in
this mode.
²OFF-Outside air is shut out and the fan will not
operate. For short periods of time only, use this
mode to prevent undesirable odors from entering
the vehicle.
²FLR-Allows for maximum heating by distributing
outside air through the floor ducts. However, the
air will not be cooled below the outside
temperature because the air conditioning does not
operate in this mode.
²MIX-Distributes outside air through the
windshield defroster ducts and the floor ducts.
Heating and air conditioning capabilities are
provided in this mode. For added customer
comfort, when the temperature control knob is
anywhere in between the full hot and full cold
positions, the air distributed through the floor
ducts will be slightly warmer than the air sent to
the windshield defroster ducts. If the temperature

is about 10ÉC (50ÉF) or higher, the air conditioner
will automatically dehumidify the air to reduce
fogging.
²
-Distributes outside air through the
windshield defroster ducts. It can be used to clear
ice or fog from the windshield. If the temperature is
about 10ÉC (50ÉF) or higher, the air conditioner will
automatically dehumidify the air to reduce fogging.
Operating tips
²In humid weather, selectbefore driving. This
will prevent your windshield from fogging. After a
few minutes, select any desired position.
²To reduce humidity buildup inside the vehicle,
don't drive with the climate control system in the
OFF position.
²Don't put objects under the front seat that will
interfere with the airflow to the back seats.
²Remove any snow,
ice or leaves from
the air intake area
(at the bottom of
the windshield).
²
If your vehicle has been parked with the windows
closed during hot weather, the air conditioner will do
a much faster job of cooling if you drive for two or
three minutes with the windows open. This will force
most of the hot, stale air out of the vehicle. Then
operate your air conditioner as you would normally.
²When placing objects on top of your instrument
panel, be careful to not place them over the
defroster outlets. These objects can block airflow
and reduce your ability to see through your
windshield. Also, avoid placing small objects on top
of your instrument panel. These objects can fall
down into the defroster outlets and block airflow
and possibly damage your climate control system.

about tire grades exactly as the government has
written it.
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 one-half (1 1/2) 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.
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

Tires that are larger or smaller than your vehicle's
original tires may also affect the accuracy of your
speedometer.
SNOW TIRES AND CHAINS
Driving too fast for conditions creates the
possibility of loss of vehicle control. Driving
at very high speeds for extended periods of time
may result in damage to vehicle components.
Snow tires must be the same size and grade
as the tires you currently have on your
vehicle.
The tires on your vehicle have all weather treads to
provide traction in rain and snow. However, in some
climates, you may need to use snow tires and
chains. Use chains on the tires only in an emergency
or if the law requires them.
Follow these guidelines when using snow tires and
chains:
²Chains may damage aluminum wheels.
²Use only Cable Type chains with size P225/55R16
or 245/45ZR17 tires. Use of SAE Class S chains
may damage vehicle.
²SAE Class S chains may be used on P205/65R15
tires.
²Install chains securely, verifying that the chains do
not touch any wiring, brake lines or fuel lines.
²Drive cautiously. If you hear the chains rub or
bang against your vehicle, stop and re-tighten the
chains. If this does not work, remove the chains
to prevent damage to your vehicle.
²If possible, avoid fully loading your vehicle.
²Remove the tire chains when they are no longer
needed. Do not use tire chains on dry roads.
