2) Check that all doors are closed and ignition key is
not inserted in ignition key cylinder.
3) While pushing ignition knob switch (1) of steering
lock unit, check if ignition knob switch can be turned
from its lock position.
If key indicator light (2) in combination meter lights in
blue and ignition knob switch can be turned from its
lock position in this check, keyless engine start

If key indicator light in combination meter lights in red
and ignition knob switch cannot be turned from its
lock position in this check, go to “Keyless Start
System Check”.
NOTE
Pushing ignition knob switch for 5 seconds
or longer causes function to protect steering
lock releasing solenoid against heat to work.
Then steering lock unit stops energizing
solenoid, preventing ignition knob switch
from turning. At the same time, key indicator
light in combination meter turns off. In such
case, take your hand off from ignition knob
switch once and operate it again.
