When adjusting the temperature, start with a driver
temperature of 73 _ F (23 _ C) until you determine
your comfort zone. If you choose 60 _ F (16 _ C), the
system will remain at maximum cooling and will not
automatically adjust fan speed or air delivery. If you
choose 90 _ F (32 _ C), the system will remain at
maximum heating and will not automatically adjust fan
speed or air delivery. Choosing either maximum setting
will not cause the system to heat or cool any faster.
Turning the knob past either maximum setting has no
effect on the operation of the system.
Passenger Temperature Offset
The PASSENGER knob changes the temperature on the
passenger's side of the vehicle. When the knob is in the
12 o'clock position, the passenger's temperature is the
same as the driver's. Turn the knob clockwise for warmer
air on the passenger's side, counterclockwise for cooler air.
set temperature is set at 60 _ F (16 _ C) or

If the driver
90 _ F (32 _ C), turning the passenger knob has no effect
because the system is locked at a maximum setting.

set Automatic Operation
Press the AUTO button to place the entire system in the
automatic mode. After a five
current settings, only the word AUTO and the outside
temperature will be shown on the digital display unless
you are in full cold 60 _ F (16 _ C) or full hot 90 _ F
(32 _ C), then the word AUTO will not display. The
system will operate to achieve your comfort set
temperature as quickly as possible. The AUTO control
system works best with the windows up and the
removable roof installed or the convertible top up.
A Typical Cold Weather Example:
Your vehicle has been parked outside overnight in cold
weather below 32 _ F (0 _ C) and you have set the
driver temperature at 73 _ F (23 _ C) and have selected
the AUTO mode. The system will automatically adjust
the temperature output to maximum heating. The fan
will start at a low speed. This is to avoid blowing cold
air into the vehicle. The length of the delay depends on
the amount of time since the engine was last started, the
outside temperature and the engine coolant temperature.
As the coolant warms up, the fan speed will gradually
increase. Air will flow to the floor with some air to
the windshield to prevent fogging under most
normal conditions.
