ENGINE MAINTENANCE
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. Failure to repair the
source of the exhaust fumes may lead to
death, personal injury or serious illness.
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.
• Whenever a change is noticed in the sound of the
exhaust system.
• Whenever the exhaust system, underbody, cab or
sleeper is damaged.
Engine Lubrication
Proper engine lubrication depends on ambient temperature
and where the vehicle will be operated. Use the recommended
oil for the weather conditions outside.
