HEATER-AIR CONDITIONING CONTROLS<br />
Heater-Air Conditioning Controls<br />
Your heat and air conditioning controls are mounted in the<br />
“D” instrument panel in conventional models. Additionally,<br />
the sleeper compartment may also contain a separate<br />
heating and cooling system with separate controls.<br />
WARNING! Exhaust fumes from the engine<br />
contain carbon monoxide, a colorless and<br />
odorless gas. Do not breathe the engine<br />
exhaust gas. A poorly maintained, damaged, or<br />
corroded exhaust system can allow carbon<br />
monoxide to enter the cab or sleeper. Entry of<br />
carbon monoxide into the cab is also possible<br />
from other vehicles nearby. Failure to properly<br />
maintain your vehicle could cause carbon<br />
monoxide to enter the cab/sleeper and causes<br />
serious illness.<br />
Never idle your vehicle for prolonged periods of<br />
time if you sense that exhaust fumes are entering<br />
the cab or sleeper. Investigate the cause of<br />
the fumes and correct it as soon as possible. If<br />
the vehicle must be driven under these conditions,<br />
drive only with the windows open. Failure<br />
to repair the source of the exhaust fumes may<br />
lead to personal harm.<br />
CONTROLS AND DISPLAY<br />
NOTES:<br />
•Keep the engine exhaust system and the vehicle’s<br />
cab/sleeper ventilation system properly<br />
maintained. It is recommended that the vehicle’s<br />

– Whenever a change is noticed in the sound of<br />
the exhaust system<br />
– Whenever the exhaust system, underbody, cab<br />
or sleeper is damaged<br />
•To allow for proper operation of the vehicle ventilation<br />
system, keep the inlet grille at the base of<br />
the windshield clear of snow, ice, leaves and<br />
other obstructions at all times.<br />
•Do not stay in the vehicle with the engine running<br />
or idling for more than 10 minutes with the vehicle’s<br />
Heater and A/C ventilation system in<br />
RECIRC or at LOW FAN SPEED. Even with the<br />
ventilation system On, running the engine while<br />
parked or stopped for prolonged periods of time is<br />
