HEATING AND AIR
CONDITIONING SYSTEM
If your vehicle has the above
system, here is how it works.
1. Air Temperature Selector
Use this to change the temper-
ature of the air coming
through the system.
Turn the temperature knob
clockwise for warmer air or
anti-clockwise for cooler air.
2. Fan Speed Selector
Use this to change the fan
speed.
There are four fan speed set-
tings:
1 , 2 , 3 and 4 .
Turn the knob to the right to
increase fan speed, or to the
left to decrease fan speed.
Turning the Fan Speed Selec-
tor all the way to the left turns
the system off. However, out-
side air still comes into the ve-
hicle when it is moving.
