lock are both on, the door lock operates as follows.
• When shifting the shift lever to any position other than P, all the doors will be
locked.
• If the vehicle is started with all doors locked, the speed- detecting automatic
door lock will not operate.

As the engine needs to be running during customization, ensure that the vehicle is
parked in a place with adequate ventilation. In a closed area such as a garage,
exhaust gases including harmful carbon mo noxide (CO) may collect and enter the
vehicle. This may lead to death or a serious health hazard.
