NOTE:
Idling the engine for a long time wastes fuel. It
wastes natural resources and causes air pollution.
Shut down the engine whenever you leave the vehi-
cle, even for a short period.
If the engine has been idling for a relatively long
time, the muffler may give off white smoke during
acceleration. This is a normal effect of the catalytic
converter. 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-weather area, the cold engine will
cause the fuel to ignite poorly, and the engine
may knock.
• If the idle speed is too low, the engine will be
abnormally noisy. Be sure to return the idle
speed to the appropriate value.
With the engine idle control turned to the automatic
control position, the engine’s idle speed is adjusted
automatically. To make the engine warm up more
quickly, take the following steps:
1. After the engine starts, turn ON the engine
warm-up switch . The exhaust brake indi-
cator will illuminate, the engine speed will
start to increase, and the exhaust brake will
operate.
NOTE:
Before turning ON the engine warm-up switch, be
sure to set the engine idle control to the AUTO posi-
tion. Black smoke may be produced if the engine
warm-up switch is turned ON with the engine idle
speed raised.
2. Continue to let the engine warm up until the
needle on the coolant temperature gauge starts
to move.
When the coolant temperature rises sufficiently,
the engine warm-up process stops automatically
and the exhaust brake indicator goes out.
3. Turn OFF the engine warm-up switch.
