7. PRECAUTIONS WHEN INSPECTING SMART KEY SYSTEM (for Entry Function)

(a) General precautions for the smart key system (for Entry Function):

(1) Always carry the electrical key transmitter.

(b) Under the following conditions, the key detection area may be reduced or the electrical key transmitter may be unable to be properly detected. This is due to the weak electromagnetic waves used for key detection.

(1) The battery is depleted.

(2) There are TV towers, electric power plants, broadcasting stations, gas stations or other facilities that generate strong electric waves nearby.

(3) Wireless communication devices, such as walkie-talkies, cell phones, cordless telephones, digital audio players, portable game systems, etc., are carried together with the electrical key transmitter.

(4) The electrical key transmitter is covered by or in contact with objects made of metal, such as coins, certain types of cards, etc.

(5) Film with some metallic content is applied to the rear window glass.

(6) Electric wave-type keyless entry systems are being operated nearby.

(7) An electrical key transmitter from another vehicle is nearby.

(8) The electrical key transmitter is placed near equipment that generates high-voltage or electrical noise.

(c) Operating range of the smart key system (for Entry Function):

(1) Due to the body shape, there are some areas in which proper system operation is difficult.

(2) Even if the electrical key transmitter is in the vehicle exterior key detection area, the electrical key transmitter may not be properly detected if the electrical key transmitter is near a window, a door handle or the center of the bumper.

(3) Even if the electrical key transmitter is in the vehicle interior key detection area, the electrical key transmitter may not be properly detected if it is on the instrument panel, in the glove box or on the floor.

(4) Depending on the way the electrical key transmitter is held, the electrical key transmitter may not operate properly.

(d) As weak electric waves are emitted from the electrical key transmitter, if a pacemaker is being used, be sure to read the pacemaker instruction manual.

(e) The smart key system (for Entry Function) will not operate under the following conditions.

(1) The procedures to cancel the smart key system (for Entry Function) are performed.

(2) There is no transmitter battery (the LED of the electrical key transmitter does not blink when a key switch is pressed).

8. PRECAUTIONS FOR ENTRY UNLOCK FUNCTION

(a) When performing an entry unlock operation, be sure to touch the backside of the front door outside handle assembly (touch sensor).

(b) If the front door outside handle assembly is touched while wearing gloves, etc., the response of the system may be delayed.

(c) When performing an entry unlock operation, confirm that the door has unlocked, and then pull the front door outside handle assembly to open the door.

(d) If the vehicle is approached quickly or the front door outside handle assembly is operated quickly, the door may not unlock. In this case, the system automatically performs the door unlock operation 4 times. However, if the front door outside handle assembly is being pulled at this time, the door may not unlock for mechanical reasons. If the door does not open when the front door outside handle assembly is pulled once, return the front door outside handle assembly to its original position. Then the door can be unlocked.

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