ON position. For a limited ELST, the

position.

checking the mirror and headlight heaters if
the engine is on). A limited ELST will test
only the legal driving lights.

fob.

brake is released or the ignition switch is

minute test duration has elapsed.
Heating and Air
Conditioning
This vehicle's heating and air conditioning
system operates in four distinct modes:
manual, automatic, semi-automatic, and
maximum defrost. Each mode provides the
driver with the greatest level of comfort and
convenience.
The recommended mode for all conditions
that do not require windshield defrosting is
the automatic mode. This mode is capable
of maintaining cab comfort under various
driving conditions without driver interaction.
The cab heater and air conditioner controls
are located together in the center of the
dash just to the right of the steering
column. The sleeper heater and air
conditioner controls are located in the
sleeper cabinet.
