AIR CONDITIONING SYSTEM
256
When the auxiliary heater is switched on or off, white
smoke and a faint odor may come from the exhaust
under the floor. If the auxiliary heater is used in
extremely cold conditions, steam may escape from the
exhaust. This is normal.
To turn off the auxiliary heater, do the following:
• Press the auxiliary heater switch once
more.
• Stop the engine.
After switching off the auxiliary heater, you can
hear a sound from the engine compartment for
about 2 minutes. This means that the electric fans
are operating to cool the auxiliary heater parts and
does not indicate a malfunction.
WARNING
• Do not touch the auxiliary heater or
its exhaust pipe when they are hot.
You could burn yourself.
After approximately 2 minutes, the fans will stop and
the auxiliary heater will switch off completely.
• Do not place any flammable objects,
such as fuel, near the auxiliary heater
or its exhaust pipe.
We recommend that you do not switch on the
auxiliary heater before 10 minutes after it has been
switched off. Otherwise, noise may be heard when
the heater is turned on.
This could cause a fire.
The auxiliary heater must be switched off
before refuelling.
NOTICE
u Do not use the wrong fuels, as this could
cause noise when the heater is turned on,
corrosion or a shorter service life of the
auxiliary heater. (Details - see "Fuel" on
page 281 in Chapter 2)
u Do not switch the auxiliary heater on and off
repeatedly within 5-minute intervals, this
could shorten the service life of the auxiliary
heater. If you must repeatedly turn the
engine on and off at short intervals (such
as on supply trips, etc.), turn off the auxiliary
heater switch.
