less than one second until the arrow starts to ash.
This will cause the turn signals to automatically
ash three times. It will ash six times if the
tow-haul mode is active. Holding the turn signal
lever for more than one second will cause the turn
signals to ash until you release the lever. The lever
will return by itself when it is released.

Driver’s Side Temperature Knob
The driver’s side knob is used to adjust the
temperature of the air coming through the system
on the driver’s side. The temperature can be
adjusted even if the system is turned off. This is
possible since outside air will always ow through
the system as the vehicle is moving forward
unless it is set to recirculation mode. See
“Recirculation” later in this section.
Turn the knob counterclockwise or clockwise to
lower or increase the cabin temperature. The
display will show the temperature setting
decreasing or increasing and an arrow pointing to
the driver will be displayed under and to the
left of the temperature setting.
Passenger’s Side Temperature Knob
The passenger’s side knob can be used to change
the temperature of the air coming through the
system on the passenger’s side of the vehicle. The
temperature can be adjusted even if the system
is turned off. This is possible since outside air will
always ow through the system as the vehicle
is moving forward unless it is set to recirculation
mode. See “Recirculation” later in this section.
Turn the knob counterclockwise or clockwise
to lower or increase the cabin temperature. The
display will show the temperature setting
decreasing or increasing and an arrow pointing to
the passenger will be displayed under and to
the right of the temperature setting.
The passenger’s temperature setting can be set to
match the driver’s temperature setting by pressing
and holding the AUTO button for four seconds. Both

Automatic Operation
AUTO (Automatic):When automatic operation is
active the system will control the inside
temperature, the air delivery, and the fan speed.
Use the steps below to place the entire system in
automatic mode:
1. Press the AUTO button.
When AUTO is selected, the display will
change to show the current driver’s set
temperature, delivery mode and fan speed.
Press the AUTO button again within
ve seconds to display the passenger’s set
temperature.
If the driver and passenger’s temperature
settings are not the same, the opposite side
temperature setting will be displayed for
an additional ve seconds. To make the
passenger’s temperature the same as
the driver’s press and hold the AUTO button
for about four seconds.
When auto is selected, the air conditioning
operation and air inlet will be automatically
controlled. The air conditioning compressor will
run when the outside temperature is over about
40°F (4°C). The air inlet will normally be set to
outside air. If it’s hot outside, the air inlet mayautomatically switch to recirculate inside air to
help quickly cool down your vehicle. The light
on the button will illuminate in recirculation.
2. Set the driver’s and passenger’s temperature.
To nd your comfort setting, start with a 74°F
(23°C) temperature setting and allow about
20 minutes for the system to regulate. Turn the
driver’s or passenger’s side temperature knob
to adjust the temperature setting as necessary.
If you choose the temperature setting of 60°F
(15°C) the system will remain at the maximum
cooling setting. If you choose the temperature
setting of 90°F (32°C) the system will remain at
the maximum heat setting. Choosing either
maximum setting will not cause the vehicle to
heat or cool any faster.
Be careful not to cover the sensor located on
the top of the instrument panel near the
windshield. This sensor regulates air
temperature based on sun load, and also
turns on your headlamps.
To avoid blowing cold air in cold weather, the
system will delay turning on the fan until
warm air is available. The length of delay
depends on the engine coolant temperature.
Pressing the fan switch will override this delay
and change the fan to a selected speed.

Pressing this button also cancels the auto
recirculation feature. To resume the auto
recirculation function, press the AUTO button.
Each time the vehicle is started, the system will
revert to the auto recirculation function.
If you select recirculation while in defrost, defog or
oor, the light in the button will ash and then go out
to let you know that this is not allowed. This is
normal and helps to prevent fogging.
When the weather is cool or damp, operating the
system in recirculation for extended periods of time
may cause fogging of the vehicle’s windows. To
clear the fog, select either defog or front defrost.
You may also notice that the A/C compressor will
run while in recirculation mode. This is normal and
helps to prevent fogging.
9(Off):Press this button to turn off the entire
climate control system. Outside air will still enter the
vehicle, and will be directed to the oor. This
direction can be changed by pressing the mode
button. The temperature can also be adjusted using
either temperature knob. Press the up or down
arrows on the fan switch, the defrost button, the
AUTO button, or the air conditioning button to turn
the system on when it is off.
