NOTE:
• When you start driving, be sure to turn OFF the
switch to deactivate the warm-up system.
• The warm-up system is used to make the
engine warm up more quickly and to make the
heater work more effectively when the vehicle is
stationary on cold days.
When the warm-up system is turned ON, the
engine’s idling speed automatically increases
and the exhaust brake operates. As a result, the
coolant warms up more quickly.
CAUTION
• Be sure to set the engine idling control vol-
ume to the AUTO position during driving.
If you drive with the engine speed raised by
the volume, abrupt starting or premature
wear of the clutch may occur.
• Turn the engine idling control volume gently,
as forcing it could damage the internal
mechanism.
• If the idling speed is set too low using man-
ual control, the engine may become exces-
sively noisy. Make sure the idling speed is
correct.
NOTE:
If the engine speed is raised by the engine idling
control volume with the Warm-up switch set to the
ON position, a black smoke may be produced.
Before turning ON the Warm-up switch, be sure to
set the engine idling control volume to the AUTO
position.
Automatic control
The engine is warmed up with the speed being
automatically controlled according to the engine
coolant temperature. (The engine speed automati-
cally decreases as the coolant temperature rises.)
Manual control
Turn the knob counterclockwise to reduce the
engine speed.
Turn it clockwise to increase the engine speed.
The engine idling control volume should normally
be placed in the automatic control position.
Engine idling control volume
WARNING
Do not increase the engine speed using the
engine idling control volume and then drive
the vehicle; it will be impossible to control
the vehicle’s speed using the accelerator
pedal.
