WARNING! Exhaust fumes from the engine con-
tain carbon monoxide, a colorless and odorless
gas. A poorly maintained, damaged, or corroded
exhaust system can allow carbon monoxide to
enter the cab or sleeper. Failure to properly
maintain your vehicle could cause carbon mon-
oxide to enter the cab and cause serious ill-
nesses.
WARNING! Never idle your vehicle for prolonged
periods of time if you sense that exhaust fumes
are entering the cab. Investigate the cause of the
fumes and correct it as soon as possible. If the
vehicle must be driven under these conditions,
drive only with the windows slightly open. Fail-
ure to repair the source of the exhaust fumes
may lead to personal harm.
