PRECAUTIONS FOR ENTRY UNLOCK FUNCTION

(a) When unlocking the doors, make sure to grasp the door outside handle assembly, ensuring contact with the sensor on the inner part of the handle. Pull the handle after confirming that the door has unlocked.

(b) If the door outside handle assembly is grasped with gloved hands, unlocking may be delayed or may not occur.

(c) When performing an entry unlock operation, make sure to check that the doors are unlocked before pulling a door outside handle assembly to open a door.

(d) When attempting to open a door suddenly or immediately after entering a vehicle exterior detection area, the door may not unlock. In this case the system automatically performs the door unlock operation 4 times. However, if a door outside handle assembly is being pulled at this time, the door may not unlock due to mechanical reasons. If the door is not unlocked, return the door outside handle to its original position and pull the handle after confirming that the door has unlocked.

(e) If the electrical key transmitter sub-assembly is brought too close to the door outside handle assembly, it may not be possible to unlock the door with the entry unlock function.

(f) After a wireless door lock, manual door lock or key-linked door lock operation is performed with the electrical key transmitter sub-assembly in an interior detection area or near the vehicle, an entry unlock operation cannot be performed. Therefore, when a wireless door lock operation is performed near a window or door handle, the entry unlock may not be able to be operated. To unlock the doors, perform a wireless door unlock operation.
