OPERATING INSTRUCTIONS
In colder climates where the temperatures are often below freezing,
sufficient warm-up for turbocharged engines is especially important. Chilled
external oil lines leading to the turbocharger will slow the oil flow until the
oil warms, reducing oil available for the bearings. Watch the engine oil
temperature or pressure gauge for a warming trend before increasing
engine idle speed (rpm).
Continue the engine warm-up until the coolant temperature reaches at
least 54°C. At this temperature, you can use partial throttle. Wait until the
coolant temperature is at least 71°C before operating at full throttle. See
Transmission Warm-Up, page 113.
Exhaust fumes from the engine contain carbon monoxide, a colourless
and odourless gas. Do not breathe the engine exhaust gas. A poorly
maintained, damaged or corroded exhaust system can allow carbon
monoxide to enter the cab or sleeper.
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/sleeper and cause serious illness.
Never idle your vehicle for prolonged periods of time if you sense that
exhaust fumes are entering the cab or sleeper. Investigate the cause of the
fumes and correct the problem as soon as possible. If the vehicle must be
driven under these conditions, drive only with the windows open. Failure
to repair the source of the exhaust fumes may lead to personal harm.
Keep the engine exhaust system and the vehicle’s cab/sleeper ventilation
system properly maintained. It is recommended that the vehicle’s exhaust
system and cab/sleeper be inspected:
• By a competent technician every 10,000km.
• Whenever a change is noticed in the sound of the exhaust system.
• Whenever the exhaust system, underbody, cab or sleeper is
damaged.
