1. PRECAUTIONS WHEN USING THE HAND-HELD TESTER
a. When troubleshooting the smart key system using the hand-held tester with the engine switch off, connect the hand-held tester to the vehicle and repeat turning any of the courtesy light switches on and off until communication between the tester and the vehicle begins (the interval between ON and OFF should be less than 1.5 sec.).
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 apply a strong impact.
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.

b. Precautions for entry unlock function:
- If the door handle is touched with gloved hands, the response may be delayed.
- Make sure that the doors are unlocked by the entry unlock function before puling on the door handle to open the doors.
- The doors may not be unlocked if the key is suddenly brought up to the vehicle or the door handle is lightly touched. If the doors cannot be unlocked, the door unlock operation will be repeated 4 times. At this time, the door may not be unlocked with the door handle being pulled for some mechanical reason. Be sure to put the handle back to the original position if the door cannot be opened by puling on the handle.
- If the key is brought too close to the transmitter on the outside of the vehicle, the door may not be unlocked because the key cannot react to the strong radio wave output from the transmitter.
- If the key is within the detection area outside of the vehicle, the door can be unlocked even when anyone other than the person who is 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's door detection area outside of the vehicle, the door will be unlocked when anyone who is carrying the key holds the driver's door handle. However, if any door handles other than that of the driver's door is held, the doors will not be unlocked.)
- If the door is not opened after the door unlock operation, the door automatically locks after approximately 30 seconds.
- If a large amount of water is applied to the door handle, because of a car wash or heavy rain, with the key in the detection area outside of the vehicle, the antenna built into the outside handle will react to unlock the door. However, the door will be locked again after approximately 30 seconds if the door is not opened.
- 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 entry lock function:
- Be sure to firmly push the lock switch on the door handle. The door may not lock if it is lightly pushed.
- If the key is brought too close to the vehicle, such as to the windows or door handle, the entry lock function may not operate. Furthermore, the key left alarm may sound and the entry unlock will not be permitted. In this case, move the key away from the vehicle and perform the entry lock operation. Then, perform the entry unlock operation again.
- Do not touch the lock switch while opening or closing the door. If the lock switch is pushed with the key carried while opening or closing the door, the door ajar alarm will sound (peeping sound for 10 seconds to the outside of the vehicle).
- Be sure to carry the key. The key left prevention function may not operate if the key is on the instrument panel, rear tray or floor, or in the glove box, resulting in key confinement.
- If the door is locked with the operation linked to the key, wireless operation or manual operation while the key is in the action areas of the cabin or luggage compartment, the entry unlock will not be permitted. If the wireless door lock operation is performed near the window or outside handle, the entry unlock may not be performed. In this case, perform the wireless door unlock operation to unlock the door.
- Entry lock will not be permitted for 3 seconds after the door lock operation (including entry lock and wireless operation).

d. Precautions for the push button start function:
- Before starting the engine, firmly depress the brake pedal until the indicator of the engine switch lights up in green.
- The power source condition (OFF, ACC, ON) is always stored in the vehicle. After the battery is removed and reinstalled, the power source condition before battery removal will be restored. Be sure to turn the engine switch off before disconnecting the cable from the battery terminal. Be careful when the power source condition before the battery becomes dead cannot be confirmed.
- After the battery is removed and reinstalled, be sure to wait 10 seconds or more before engine start. The engine may not start immediately after the battery is reinstalled.
- If the key is held over the engine switch to start the engine because the key battery has died, the following warning will sound:

1. Driver's door open -> close:
- Warning to inform that the P position power remains on
- Warning to inform that any of power for the shift positions other than P remains on

2. Doors other than the driver's door open -> close:
- Warning to inform that any of the passengers is carrying the key out of the vehicle

HINT: These warnings will sound because whether the key is in the cabin or not cannot be determined. They do not indicate system malfunctions.

e. Precautions for the function to prevent key confirmation in the luggage compartment:
- Do not place the key in the luggage compartment.
If the luggage compartment is closed with the key in it when all the doors are locked, the alarm the inform key confinement will operate (peeping sound for 2 seconds to the 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.
- If the luggage compartment 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 and take out the key.
- The alarm may erroneously operate in the following conditions. If you can confirm that you carry the key or 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 wireless operation to open the luggage compartment.

1. The key is brought into the cabin after the luggage compartment is opened, then the luggage compartment is closed.

2. The luggage compartment is closed by the person who is carrying the key.
- If the alarm operates when the luggage compartment is closed with all the doors locked, the key must be in the cabin or luggage compartment. Check the cabin and luggage compartment to find the key.
- If the luggage compartment is closed with the key in it when all the doors are locked, the alarm will sound and the luggage compartment can be opened. This may cause vehicle theft.
- Do not open or close the luggage compartment 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 can be opened, causing vehicle theft.

f. Precautions for the battery built into the key and the vehicle battery:
- When the door is being locked, the vehicle battery is used to transmit a radio wave. 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 (For the cancellation, see customize parameters.
- When the door is being locked with the key in the action area of the door 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)).

g. Precautions for the smart unlock mode switching function:
- Do not perform the smart unlock mode switching within a 1 m (3.3 ft) area around the vehicle.
- The smart unlock mode switching may not be performed within 5 seconds after the previous switching. Wait 5 seconds or more before performing the next switching.

h. Precautions for the steering lock function:
- If the vehicle skids for some reason such as engine stall, do not open the doors until the vehicle completely stops safely. If any of the doors is opened during vehicle skid, the steering lock may operate.
- If the engine start and stop are repeated in a short interval, the engine may not be started. Wait 10 seconds or more and then start the engine.
- Be careful when the battery is dead because the steering lock does not operate at this time.
- After replacing the steering lock assembly, open and close the driver's door. The engine may not start if the driver's door is not opened and closed.
