WARNING! Exhaust fumes from the engine contain
carbon monoxide, a colorless and odorless
gas. Do not breathe the engine exhaust gas.
A poorly maintained, damaged or corroded exhaust
system can allow carbon monoxide to enter
the cab. Entry of carbon monoxide into the
cab is also possible from other vehicles nearby.
Failure to properly maintain your vehicle could
cause carbon monoxide to enter the cab and
cause serious illness.
CAUTION: 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. Failure to repair the source of the exhaust
fumes may lead to personal harm.
PART 8: MAINTENANCE AND SERVICE
NOTE: Keep the engine exhaust system and the
vehicle’s cab ventilation system properly maintained.
It is recommended that the vehicle’s
exhaust system and cab be inspected:
• By a competent technician every 15,000 miles/
24,000 km
• Whenever a change is noticed in the sound of
the exhaust system
• Whenever the exhaust system, underbody, or
cab is damaged
NOTE: Use only an exact replacement DPF in exhaust
systems. Using a noncompliant DPF as a replacement
could violate these standards and also
void the emission system’s warranty.
