CONTROLS AND INSTRUMENTS
Warm-Up Switch
V
This switch is used to allow engine coolant
to warm up faster at low temperatures to
increase the efficiency of the heater and/or
the defroster, or to increase the efficiency
of the heater while the vehicle is parked.
Start the engine and press the warm-up
switch. The warm-up system indicator light
on the instrument panel comes on and the
engine warms up faster.
After the engine has warmed up, press the
switch again to turn the warm-up system to
the "OFF" position. The indicator light goes
out.
NOTE
The warm-up system does not
operate even if the warm-up switch
is pressed when it is sufficiently
warm, the engine is warm enough or
the vehicle is already being driven.
If your vehicle is equipped with an
idling control knob, increasing the
engine speed to 1,000 r/min or
above using the knob deactivates
the warm-up system, in this case
the system then does not work even
if the warm-up switch is pressed and
the warm-up system indicator light
comes on.
