5-10 Switches and controls
CAUTION
Racing the engine immediately after it has
started causes excessive wear of cylinders and
pistons, leading to engine malfunction. Be sure
to warm up the engine to operating temperature
before full load operation according to the pro-
cedures described here.
NOTE:
Idling the engine for long time wastes fuel, and is
therefore detrimental to environmental protection
and resource conservation. So shut down the
engine whenever you leave the vehicle, even for a
short period.
If you start to drive immediately after starting the
engine (while the engine is still cold), you will
encounter the following problems:
• In a cold region, the extreme coldness of the
engine will cause poor ignition of fuel, making
the engine prone to knocking.
You may encounter any or all of the following condi-
tions. They are due to the actions particular to the
oxidation catalyst inside the diesel particulate filter
(DPF) and do not indicate any abnormalities.
• White smoke from the exhaust pipe when set-
ting the vehicle in motion after idling the engine
for a relatively long-time or when accelerating
the vehicle.
• White smoke from the exhaust pipe when the
vehicle starts off immediately after the engine is
started.
• The exhaust smells irritating (with a vinegar-like
odor).
