■Using the automatic mode
Fan speed is adjusted automatically according to the temperature setting and ambi-
ent conditions. As a result, the following may occur:
●The system may switch automatically to recirculated air mode when the coolest
temperature setting is selected when the ambient temperature is high.
●Immediately after is pressed, the fan may stop for a while until warm or
cool air is ready to flow.
●Cool air may flow to the area around the upper body when the heater is on.
■Switching between outside air and recirculated air modes
Recirculated air mode or outside air mode may be automatically switched to in
accordance with the temperature se tting and the inside temperature.
■Using the system in outside air mode
As hot air from the hood grilles may flow through the air outlets, it is recommended
that the air conditioning system be turned on while outside air mode is used.
■Using the system in recirculated air mode
The windows will fog up more easily if recirculated air mode is used.
■When is selected for the air outlets used
For your driving comfort, air flowing to th e feet may be warmer than air flowing to
the upper body depending on the temperature setting.
■When the outside air temperature approaches 32 F (0C)
The air conditioning system may not operate even when
is pressed.
■Air conditioning odors
●During use, various odors from inside and outside the vehicle may enter into
and accumulate in the air conditioning sy stem. This may then cause odor to be
emitted from the vents.
●To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air mode
prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short period of time
immediately after the air conditioning system is started in automatic mode.

■To prevent the windshield from fogging up
Do not use
during cool air operation in extremely humid weather. The differ-
ence between the temperature of the outside air and that of the windshield can
cause the outer surface of the windshield to fog up, blocking your vision.
NOTICE
■To prevent battery discharge
Do not leave the air conditioning system on longer than necessary when the engine
is stopped.

Maintenance and care
CAUTION
The engine compartment contains many mechanisms and fluids that may move sud-
denly, become hot, or become electrically energized. To avoid death or serious injury,
observe the following precautions:
■When working on the engine compartment
●Keep hands, clothing, and tools away from the moving fan and engine drive belt.
●Be careful not to touch the engine, exhaust manifold, etc. right after driving as
they may be hot. Oil and other fluids may also be hot.
●Do not leave anything that may burn easily, such as paper or rags, in the engine
compartment.
●Do not smoke, cause sparks or expose an open flame to fuel. Fuel fumes are flam-
mable.
■When working near the electric cooling fan
Be sure the ignition switch is in the “LOCK” position.
With the ignition on, the electric cooling fan may automatically start to run if the air
conditioning is on. ( P. 2 6 1 )
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from getting
in the eyes.
NOTICE
■If you remove the air cleaner filters
Driving with the air cleaner filters remo ved may cause excessive engine wear due
to dirt in the air. Also a backfire could cause a fire in the engine compartment.
