Driver's Section Temperature Setting
The temperature displayed on the

temperature set point.
To increase the temperature set point,
press the "+" sign, to decrease the
temperature set point, press the " - "
sign. Temperature range is between
60°F and 82°F (16°C to 28°C). On the
driver’s side only, asking for a
temperature set point above 82°F (28°C)
will keep the coolant valve open and
“FUL” will be displayed.
In case of interior temperature sender
unit failure, the coolant valve will remain
open and three lines “- - - “will be
displayed.
WARNING
Warm temperatures may cause drowsiness and
affect alertness while driving. Keep the
temperature comfortable but not too high.

The temperature displayed on the
passenger's side HVAC control unit is
the actual temperature in the

To increase or decrease the temperature
set point in the passenger's area, press

these buttons will flash the displayed set
point and the word "SET" will highlight.
Temperature range is between 60°F and
82°F (16°C to 28°C).
In case of interior temperature sender

control the temperature by adjusting the
temperature set point above 72°F (22°C)
to heat and below 72°F (22° C) to cool.
NOTE
Upon starting of the vehicle, when the ambient
temperature is very cold and so is the inside of the
vehicle, the HVAC control unit will allow a

passenger’s area set point to help warming up of
the area because some parts of the vehicle like the
seats and the overhead compartments accumulate
cold.
