Entry And Start System Precaution

When using the intelligent tester to troubleshoot the LIN communication line: Connect the intelligent tester to the vehicle, and turn a courtesy light switch on and off at 1.5 second intervals until communication between the tester and vehicle begins.

After all DTCs are cleared, check if the trouble occurs again 6 seconds after the engine switch is turned on (IG).

Precautions for the key:
The key is a precision instrument. Be sure to observe the following:

1. Do not drop or strike the key.
   

2. Do not keep the key in a high temperature area for a long time.
   

3. Do not use an ultrasonic washing machine to clean the key.
   

4. Keep the key away from magnets or magnetized items during use.
   

5. Do not attach any stickers to the key.
   

Precautions for the entry unlock function:

1. As the sensor is built into the backside of the outside door handle, the user must touch the backside part of the handle when performing the unlock function.
   

2. If touched with gloved hands, the response of the door may be delayed.
   

3. During the entry unlock operation, if the door handle is pulled before the door unlocks, the unlock function cannot be completed. Confirm that the door has been unlocked before pulling the door handle to open the door.
   

4. Make sure that the doors are unlocked when touching the touch sensor on the outside door handle while the key is being carried.
   If the doors cannot be unlocked, the certification ECU orders each door ECU to perform the door unlock operation 4 times at intervals of 0.75 seconds.
   At this time the door may not be unlocked because the handle is being pulled due to some mechanical reasons.
   Be sure to return the door handle to its original position.
   If the door cannot be opened by pulling the handle, perform the entry unlock operation again.
   

5. If the key is too close to the oscillator on the outside of the vehicle, the door may not be unlocked because the key cannot react to the strong wave output from the transmitter.
   

6. If the key is within the vehicle exterior detection area, the door can be unlocked even when a person other than the person carrying the key holds the door handle.
   However, the doors other than the door that the codes match will not be unlocked.
   (If the key is within the driver side door's detection area outside the vehicle, the doors will be unlocked when the person carrying the key holds the driver side door handle. However, if any door handle other than that of the driver side door is held, the doors will not be unlocked).
   

7. If a door is not opened after the door unlock operation, the doors automatically lock after approximately 30 seconds.
   

8. If a large amount of water is applied to the door handle due to a car wash or heavy rain, and the key is brought within the vehicle exterior detection area, it may cause the doors to be unlocked.
   However, the doors will be locked again after approximately 30 seconds if a door is not opened.
   

9. If the key of the entry and start system is used while it is being carried with the key of another entry and start system, the time before the entry unlock operation will become longer than usual. This is not a malfunction.
   

Precautions for the entry lock function:

1. When performing the entry lock operation, firmly press the lock switch on the outside door handle.
   If pressed too quickly or lightly, the entry lock may not operate.
   

2. It is possible that signals output from the indoor electrical key oscillator may leak through the window. Also, if the key is too close to a door electrical key oscillator, the oscillator output signals are too strong and the key cannot respond. As a result, when the key is near the vehicle interior (window, door handle), the entry lock function may not operate. Also, the warning buzzer may sound and the entry unlock operation may stop functioning. In this situation, move the key away from the vehicle interior (window, door handle), perform the entry lock operation and perform the entry unlock operation.
   

3. Do not touch the lock switch while opening or closing the door.
   If the lock switch is pressed when opening or closing the door while the key is being carried, the door ajar warning buzzer sounds. (Beeps outside the vehicle for 10 seconds.)
   

4. If the key is on the instrument panel, rear package tray or floor, or in the glove box, the key reminder function may not operate and the key may be locked in the vehicle. Always carry the key.
   

5. If the key is outside the vehicle but is very close to a window or door handle (the ECU determines that the key is inside the vehicle) and the transmitter or mechanical key is used to lock the doors (entry lock is not used), entry unlock will not operate. To unlock the doors, perform a wireless door unlock operation. The entry lock function operates in this way to prevent the user from unintentionally unlocking the doors from outside the vehicle. For example, when a user operates the wireless door lock operation from inside the vehicle, radio waves from a door electrical key oscillator may leak into the vehicle interior and the doors may unlock.
   

6. To allow the user enough time to check if the doors are locked after performing a door lock operation (entry lock function or wireless door lock operation), the entry unlock function will not be permitted for 3 seconds after the door lock operation.
   

Precautions for the entry ignition function:

1. To start the engine, first depress the clutch pedal*1 (brake pedal*2) firmly until the engine switch indicator illuminates in green.
   

   HINT:

   *1: for Manual Transaxle

   *2: except Manual Transaxle

2. When operating the engine switch, firmly press the switch. If the switch is pressed too quickly, power source control and engine starting may not operate.
   

3. Do not touch the engine switch with oily hands.
   

4. If the vehicle has been in a hot location for an extended period of time, be careful when touching the engine switch. It may be very hot and lead to burns.
   

5. Take care to avoid spilling beverages on the engine switch. Keep all liquids away from the engine switch.
   

6. The vehicle continually records the power source mode (off, on (ACC), on (IG), start). When the battery cable is disconnected and reconnected, the power source mode will return to the mode it was in before disconnecting the battery cable. Always disconnect the battery cable before turning the power off. When the vehicle battery is fully depleted, power is cut, and the power source mode before the power was cut is unknown, so be extremely careful.
   

7. Do not connect any electronic products to the ACC, IG1 or IG2 coil side wiring, as the vehicle power supply may be unable to be turned on, or other problems may occur.
   

8. After the battery cable has been disconnected and reconnected, the engine will not start on the first attempt. The engine will start normally on the second attempt.
   

9. When starting the engine immediately after reconnecting the battery cable, connect the cable and wait at least 10 seconds before attempting to start the engine. The engine may not start when attempting an engine start immediately after disconnecting and reconnecting the battery cable.
   

10. When the key battery is depleted and the key is held up to the engine switch to start the engine, a warning alarm may sound. This does not indicate actual malfunctions. The alarm under such conditions is caused by the system being unable to determine whether the key is inside the cabin due to the key battery depletion. However, the warning alarm is designed to indicate that the key is being taken out of the cabin by means of the opening and closing of any door other than the driver door.
    

Precautions for back door entry function:
Even if the key is within the door electrical key oscillator (back door) detection area, the back door cannot be opened if the key is in the following areas:

1. Near the center of the tuner
   
2. Too close to the ground or in a high place
   

Precautions for the battery built into the key and the vehicle battery:

1. When the door is being locked, the vehicle battery is used to transmit radio waves. The battery may be dead if the vehicle remains stopped for a long time. If the vehicle is not used for a long time, remove the battery from the vehicle or cancel the entry and start system.
   

2. When the door is being locked with the key in the detection area of a door electrical key oscillator, the battery is used for regular communication between the key and vehicle. If the vehicle is not used, keep the key away from the vehicle (more than 2 m (6.6 ft.)).
   

3. After disconnecting and reconnecting the battery cable, the entry unlock function may not operate. If this occurs, perform a wireless door unlock and lock operation.
