OPERATING INSTRUCTIONS
Do not drive with visibility reduced by fog condensation or frost on
the windscreen. Your view may be obscured which may result in
death, personal injury, equipment or property damage. For clear
visibility and safe driving it is extremely important for you to follow
the instructions pertaining to the function and use of the ventilation/
heating and defogging/defrosting system. If in doubt, consult your
dealer. Maximum heating output and fast defrosting can be obtained
only after the engine has reached operating temperature.
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. 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, resulting in death or personal injury.
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 open.
Failure to repair the source of the exhaust fumes may result in death,
personal injury, equipment or property damage.
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 10,000 kilometers
• whenever a change is noticed in the sound of the exhaust system
• whenever the exhaust system, underbody or cab is damaged
To allow for proper operation of the vehicle ventilation system, keep the
inlet grille at the base of the windscreen clear of snow, ice, leaves and
other obstructions at all times.
Do not stay in the vehicle with the engine running or idling for more than
10 minutes with the vehicle’s heater and A/C ventilation system in RECIRC
or at LOW FAN SPEED. Even with the ventilation system on, running
the engine while parked or stopped for prolonged periods of time is not
recommended.
