Outside Air Temperature Sensor
This sensor is located in the air intake under the front
bumper of the vehicle. Information from this sensor
is used for the outside air temperature readings shown
on the digital display for the automatic climate
control system.
If the outside temperature goes up, the displayed
temperature will not change until:
The vehicle’s speed is above 20 mph (32 km/h) for
one and a half minutes.
The vehicle’s speed is above 45 mph (72 km/h) for
one minute.
These delays help prevent false readings. If the
temperature goes down, the outside temperature display
is updated immediately.
If the vehicle has been turned off for more than three
hours, the current outside temperature will be shown
when you start the vehicle. If it has been turned off for
less than three hours, the temperature will be recalled
from the previous vehicle operation.
Inside Temperature Sensor
This sensor is located to the left of the ignition switch.
The automatic climate control system uses this sensor to
receive information, so if you block or cover it, the
system will not function properly.
Air Conditioning
On very hot days, the vehicle will cool down more
quickly and economically if you open the windows long
enough to let hot inside air escape. Then keep the
windows closed in order to allow the air conditioning to
work best. Maximum cooling will occur when the
recirculate setting is operating, airflow direction is in the
upper mode, and the temperature control knob
(on a manual climate control system) is turned all the
way to the blue area. These settings will be selected
by the Automatic Electronic Dual Climate Control
System if operating in AUTO when maximum cooling
is required.
When the air conditioning is on, you may sometimes
notice slight changes in the vehicle’s engine
performance and power. This is normal. The system is
designed to help fuel economy while maintaining the
desired cooling level.
