Starting System: Service Precautions

2UR-FSE STARTING: SMART ACCESS SYSTEM WITH PUSH-BUTTON START: PRECAUTION

1. PRECAUTIONS FOR PUSH-BUTTON START FUNCTION:

(a) Before starting the hybrid control system, firmly depress the brake pedal until the indicator in the power switch turns green.

(b) The power source mode (OFF, ON (ACC), ON (IG), ON (READY)) is always retained in memory by the vehicle. If the battery is disconnected, the power source mode that was present before the disconnection will be restored after the battery is reconnected. Be sure to turn the power switch OFF before disconnecting the cable from the negative battery terminal. Be careful if the power source mode with a discharged battery is not known.

(c) After the battery is reconnected, be sure to wait 10 seconds or more before attempting to start the hybrid control system. The hybrid control system may not start immediately after the battery is reconnected.

(d) If the LEXUS mark of the key or card key is touched to the power switch to start the hybrid control system when the key or card key battery is depleted or affected by wave noise, etc., the following warnings will sound:

(1) Driver's door open -> closed

An exit warning will sound if the shift lever is in a position other than P and the power source is in a mode other than OFF.

An exit warning will sound if the shift lever is in the P position and the power source is in a mode other than OFF.

(2) Doors other than the driver door open -> closed

A warning will sound to indicate that the key or card key has been taken out of the vehicle.

These warnings will sound because it is not possible for the vehicle to determine if the key or card key is present in the vehicle (due to the depleted key battery). These warnings do not indicate system malfunctions.
