System is controlled by setting the
desired temperature.
1. Press the AUTO button.
The modes, fan speeds, air intake
and air-conditioning will be controlled
automatically by the temperature set-
ting you select.2. Turn the temperature control knob
to the desired temperature. If the
temperature is set to the lowest set-
ting (Lo), the air conditioning sys-
tem will operate continuously. After
the interior has cooled sufficiently,
adjust the knob to a higher temper-
ature set point whenever possible.
To turn the automatic operation off,
select any function of the following:

For your convenience and to improve
the efficiency of the climate control,
use the AUTO button and set the
temperature to 72°F (22°C).
Information
In some situations, the air conditioning
system is used to control the tempera-
ture of the high voltage battery. This
may occur when the outside ambient
air temperature is high or when the
vehicle is charging. If this occurs, you
may hear sounds from operation of the
A/C compressor and/or cooling fan.
Also, when the outside ambient tem-
perature is high, the A/C performance
in the cabin may be reduced while
driving due to operation of the cooling
system for the high voltage battery.

Air conditioning system operation
tips
If the vehicle has been parked in
direct sunlight during hot weather,
open the windows for a short time
to let the hot air inside the vehicle
escape.
After sufficient cooling has been
achieved, switch back from recircu-
lation mode to fresh mode.
To help decrease the humidity
inside the vehicle on rainy or humid
days, operate the air conditioning
system with the windows and sun-
roof closed. It is useful to operate the air condi-
tioning system periodically through-
out the year. Turn on the A/C sys-
tem at least once a month for a few
minutes to maintain system pres-
sure and help optimize A/C per-
formance.
Note that if you operate the air con-
ditioner to cool your vehicle with
the mode set to or when
the outside relative humidity is
high, moisture may collect on the
outer surface of the windshield
glass causing the windshield to fog
up on the outside and limit your
visibility.
If this occurs, use the windshield
wipers to clear the glass. In addi-
tion, change the mode selection
knob or button on the climate con-
trol system to the mode to
redirect cooling air away from the
windshield.

while defrosting or defogging, set the
mode to the floor-defrost position.
Before driving, clear all snow and
ice from the windshield, rear win-
dow, side view mirrors, and all side
windows.
Clear all snow and ice from the hood
and air inlet in the cowl grill to
improve heater and defroster effi-
ciency and to reduce the probability
of fogging up the inside of the wind-
shield.To Defog Inside Windshield

Do not let ice and snow accu-
mulate underneath
Under some conditions, snow and
ice can build up under the fenders
and interfere with the steering. When
driving in severe winter conditions
where this may happen, you should
periodically check underneath the
car to be sure the movement of the
front wheels and the steering com-
ponents is not obstructed.
Don't place foreign objects or
materials in the motor compart-
ment
Placement of foreign object or mate-
rials which prevent cooling of the
vehicle, in the motor compartment,
may cause a failure. The manufactur-
er is not responsible for the damage
caused by such placement.
To keep locks from freezing
To keep the locks from freezing,
squirt an approved de-icer fluid or
glycerine into the key opening. If a
lock is covered with ice, squirt it with
an approved de-icing fluid to remove
the ice. If the lock is frozen internally,
you may be able to thaw it out by
using a heated key. Handle the heat-
ed key with care to avoid injury.
