If the vehicle is left in ACCESSORY mode for more than 20 minutes or IGNITION ON

switch will automatically turn off. However, this function cannot entirely prevent battery
discharge. Do not leave the vehicle with the engine switch in ACCESSORY or IGNI-
TION ON mode for long periods of time when the engine is not running.

Steering lock
■
After turning the engine switch off and opening and closing the doors, the steering wheel
will be locked due to the steering lock function. Operating the engine switch again auto-
matically cancels the steering lock.

■
"Steering Lock active" will be displayed on the
multi-information display.
Check that the shift lever is in P. Press the
engine switch while turning the steering wheel
left and right.
Steering lock motor overheating prevention
■
To prevent the steering lock motor from overheating, operation of the motor may be sus-
pended if the engine is turned on and off repeatedly in a short period of time. In this case,
refrain from operating the engine switch. After about 10 seconds, the steering lock
motor will resume functioning.
