Smart Key System (for Entry Function)
THEFT DETERRENT / KEYLESS ENTRY: SMART KEY SYSTEM (for Entry Function): PRECAUTION
1. PRECAUTIONS WHEN USING TECHSTREAM
(a) When troubleshooting the smart key system using the Techstream with the engine switch off, connect the Techstream to the vehicle and repeat turning any of the courtesy light switches on and off until communication between the Techstream and the vehicle begins (the interval between ON and OFF should be less than 1.5 seconds).
(b) After DTCs are all cleared, check if the trouble occurs again 6 seconds after the engine switch is turned on (IG).
2. PRECAUTIONS FOR EACH FUNCTION
(a) 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.
(6) If a key is lost, delete all registered key ID codes and then reregister the remaining keys.
(b) 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 of the handle when performing the unlock function.
(2) If the backside of the handle is 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 (smart key ECU assembly) orders the main body ECU (instrument panel junction block) 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 electrical key 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 60 seconds.
(8) If a large amount of water is applied to the door handle due to a car wash or heavy rain, the key being within the vehicle exterior detection area may cause the doors to be unlocked.
However, the doors will be locked again after approximately 60 seconds if a door is not opened.
(9) If the key of the smart key system is used while it is being carried with the key of another smart key system, the time before the entry unlock operation will become longer than usual. This is not a malfunction.
(c) Precautions for the entry lock function:
(1) When performing the entry lock operation, firmly press the lock switch on the outside door handle.
If the lock switch is pressed too quickly or lightly, the entry lock may not operate.
(2) Signals output from the indoor electrical key antenna may leak through the window. Also, if the key is too close to a door electrical key oscillator, the electrical key oscillator output signals are too strong and the key cannot respond. As a result, when the key is near the vehicle (window, door handle), the entry lock function may not operate. Also, the key reminder warning buzzer may sound and the entry unlock operation may stop functioning. In this situation, move the key away from the vehicle (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 a door.
If the lock switch is pressed when opening or closing a 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, 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.
(d) Precautions for luggage compartment door entry function:
Even if the key is within the outside electrical key oscillator (luggage compartment) detection area, the luggage compartment door cannot be opened if the key is in the following areas:
* Near the center of the bumper
* Too close to the ground or in a high place
(e) Precautions for the function to prevent key confinement in the luggage compartment:
(1) Do not place the key in the luggage compartment.
If the luggage compartment door is closed with the key in it when all the doors are locked, the alarm to indicate key confinement will operate (beeping sound for 2 seconds outside of the vehicle). However, the alarm may not operate for some reason relating to the key location (near the spare tire or the side of the luggage compartment), the key condition (covered with metal or near metal), or ambient radio waves.
(2) If the luggage compartment door is closed with the key in it when any of the doors is unlocked or open, the key confinement prevention function will not operate. In this case, use the luggage compartment opener in the cabin to open the luggage compartment door and take out the key.
(3) The alarm may erroneously operate in the following conditions. If you can confirm that you are carrying the key or that the key is in the cabin, there is no problem. The entry luggage compartment open function may not operate if the alarm erroneously operates. In this case, use the luggage compartment opener in the cabin or perform a wireless operation to open the luggage compartment door.
- The key is brought into the cabin after the luggage compartment door is opened, and then the luggage compartment door is closed.
- The luggage compartment door is closed by the person who is carrying the key.
(4) If the alarm operates when the luggage compartment door is closed with all the doors locked, the key is in the cabin or luggage compartment. Check the cabin and luggage compartment to find the key.
(5) If the luggage compartment door is closed with the key in it when all the doors are locked, the alarm will sound and the luggage compartment door can be opened. This may increase the risk of the vehicle being stolen.
(6) Do not open or close the luggage compartment door after all the doors are locked if you want to keep the spare keys in the cabin. As a result, the alarm may sound and the luggage compartment door can be opened. This may increase the risk of the vehicle being stolen.
(f) Precautions for the battery built into the key and the vehicle battery:
(1) The key is constantly checking for signals from the vehicle, which requires power from the key's built-in battery. The life of the battery is approximately 1 to 2 years depending on the usage conditions. Be sure to replace the battery when its power is low. When replacing the battery, do not touch the inner circuit board or other inner parts.
(2) The key is constantly checking for signals from the vehicle using battery power to determine whether the key is being used or not. Even if the user is carrying 2 keys and only 1 key is used, both keys will consume battery power.
(3) The key receives radio waves at approximately 314 MHz. If the key continuously receives strong, identical frequency waves, the key's battery may be drained. Store the key at least 1 m (3.3 ft.) away from TVs, personal computers, or other electrical products.
(4) When a 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 smart key system.
(5) When a 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.)).
(6) 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.
(g) Precautions for the entry unlock mode switching function:
(1) Use the entry unlock mode switching function within a 1 m (3.3 ft.) area around the vehicle.
(2) The entry unlock mode switching function cannot be used within 5 seconds of the previous mode change. Wait 5 seconds or more before performing a mode change.
