Climate Control System
(OPTION)
Your vehicle's heater and air conditioner
work best if you keep your windows
closed. Your vehicle also has flow-
through ventilation, described later in
this section, to bring outside air into
your vehicle.
If you have the optional engine block
heater and use it during cold weather,
0°F (-18°C) or lower, your heating
system will more quickly provide heat
because the engine coolant is already
warmed. See the Index under Engine
Block Heater.
OFT: Press to turn the system
off. Press
any climate control setting to turn the
system on.
:
Slide the lever to the right to
increase fan speed, to the left to
decrease fan speed.
Temperature Control Lever: Slide the
lever to the right for warmer, heated air;
slide it to the left for cooled air.
Air Conditioner
When the temperature outside is above
freezing, the air conditioner compressor
will automatically condition the air
when you press RECIRC (the
AIC
indicator light will glow), MIX or DEF
(the AIC indicator light will not glow).
Press AIC (the AIC indicator light will
glow) to condition the air when you
press UPPER, BI-LEV or
LOWER.
To turn off the air conditioner
compressor in these settings, press AIC
again (the indicator light will go off).
Each time you turn on the ignition, the
air conditioner will default to the setting
you had selected before last turning off
the ignition.
When the air conditioner compressor is
on, you may sometimes notice slight
changes in your vehicle's engine
performance and power. This is normal,
because the system is designed to help
fuel economy while it maintains the
desired cooling level.
The air conditioner removes moisture
from the air, so you may sometimes
notice water dripping from under your
vehicle when it is idling or after it has
been turned off. This is normal.
On very hot days, your vehicle will cool
down more quickly and economically if
you open the windows long enough to
let hot inside air escape. For all settings,
adjust the temperature control lever and
fan
speed as desired.
