■ Steering lock function
● After turning the power switch off and
opening and closing the doors, the steer-
ing wheel will be locked due to the steer-
ing lock function. Operating the power
switch again automatically cancels the
steering lock.
● When the steering lock cannot be
released, “Push Power Switch While
Turning Steering Wheel in Either Direc-
tion” will be displayed on the multi-infor-
mation display.
Press the power switch shortly and firmly
while turning the steering wheel left and
right.
● To prevent the steering lock motor from
overheating, the motor may be sus-
pended if the hybrid system is turned on
and off repeatedly in a short period of
time. In this case, refrain from operating
the power switch. After about 10 sec-
onds, the steering lock motor will resume
functioning.
