press the AUTO button. Then set
the desired temperature by pressing
either side of the TEMP button:

temperature f rom its current level to
the set temperature.
When you set the temperature to its
lower limit (57°F/14°C ‘‘ ’’)
or its upper limit (87°F/31°C
‘‘ ’’), the system runs at f ull
cooling or heating only. It does not
regulate the interior temperature.
When the temperature is set
between the lower and upper limits, the system regulates the interior
temperature to the set value.
In cold weather, the f an will not
come on automatically until the
vehicle has been driven f or a short
time and the heater starts to develop
warm air.
Pressing the OFF button shuts the
climate control system of f . Keep the
system of f only f or short periods. To

mal conditions. It should be replaced
every 15,000 miles (24,000 km) if you
drive primarily in urban areas that
have high concentrations of soot in
the air f rom industry and diesel-pow-
ered vehicles. Replace it more of ten
