The ignition switch is equipped with an anti-theft steering lock device. The ignition lock is designed so that the ignition switch position cannot be switched to OFF until the shift selector is moved to the P (Park) position (CVT) or N (Neutral) position (MT). When the ignition switch cannot be pushed toward the OFF position, proceed as follows: 1. Move the shift selector into the P (Park) position (CVT) or N (Neutral) position (MT). 2. Push the ignition switch. The ignition switch position will change to the ON position. 3. Push the ignition switch again to the OFF position. The shift selector can be moved from the P (Park) position if the ignition switch is in the ON position and the brake pedal is depressed. In order for the steering wheel to be locked, it must be turned about 1/8 of a right or left turn from the straight-up position. To lock the steering wheel, push the ignition switch to the LOCK position. To unlock the steering wheel, push the ignition switch while slightly turning the steering wheel right and left. If the battery of the vehicle is discharged, the push-button ignition switch cannot be turned from the LOCK position. Some indicators and warnings for operation are displayed on the vehicle information display. See "Vehicle information display" in the "Instruments and controls" section. ACC has a battery saver feature that will turn the ignition switch to the OFF position after 1 hour under the following conditions: ● all doors are closed. ● shift selector is in P (Park). The battery saver feature will be cancelled if any of the following occur: ● any door is opened. ● shift selector is moved out of the P (Park). ● ignition switch changes position.
