knob to the highest temperature
setting and the fan control knob to
the highest fan speed. Select the
front defrost button on the climate
control display. After the engine
warm-up period, warm air will be
directed to the front windshield.

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.
If the engine temperature is still
cold after starting, then a brief
engine warm up period may be
required for the vented air flow to
become warm or hot.Manual Climate Control System

Auto Defogging System
(if equipped)
Auto defogging helps reduce the
possibility of fogging up the inside of
the windshield by automatically
sensing the moisture that accumu-
lates on inside the windshield.
The auto defogging system operates
when the heater or air conditioning is
on.When the Auto Defogging
System operates, the indi-
cator will illuminate.
If a high amount of humidity is
detected in the vehicle, the Auto
Defogging System will be enabled.
The following steps will be performed
automatically:
Step 1 : Outside air position
Step 2 : Operating the air condition-
ing
Step 3 : Blowing air toward the wind-
shield
Step 4 : Increasing air flow toward
the windshield
If the air conditioning is off or recircu-
lated air position is manually select-
ed while Auto Defogging System is
ON, the "ADS OFF" symbol will blink
3 times to signal that the manual
operation has been canceled.
To cancel or reset the
Auto Defogging System
Press the front windshield defroster
button for 3 seconds when the igni-
tion switch is in the ON position.
When the Auto Defogging System is
canceled, the ADS OFF symbol will
blink 3 times and ADS OFF will be
