1. PRECAUTIONS FOR USERS WITH PACEMAKERS
(a) Weak electric waves are emitted from the key. If a pacemaker is being used, read the pacemaker
instruction manual before using the smart key system.
If implanted pacemakers or cardioverter defibrillators are being used, make sure they are not
brought near the electrical key antenna and electrical key oscillator. The electric waves may
If electric devices (for medical purposes) other than an implantable pacemaker or implantable
cardioverter defibrillator are used, confirm with the manufacturer if electric waves affect their
operation. Electric waves may affect the electric devices.
The smart key system can be set so that it does not operate. Refer to Key Cancel for more
2. PRECAUTIONS FOR SMART KEY SYSTEM AND KEY
(a) The smart key system does not operate in the following situations. If it does not operate at all, check that
the following is not the cause.
(1) The key cancel operation has been performed.
(2) There is no key battery.
(Key indicator does not blink when key switches are pressed).
(b) The key must be in the possession of the user.
(A requirement of the smart key system. This is to make sure the user maintains a habit of carrying the
(c) As the key only emits weak electric waves, if any of the following conditions are met, the detection area ofthe key may become smaller or the key may become undetectable.
In this case, remove the cause or unlock the door using the mechanical key.
(1) The battery is depleted.
(2) There are TV towers, electric power plants, broadcasting stations, gas stations or other areas of strong
electric wave output nearby.
(3) Wireless products such as cell phones, etc. are carried with the key.
(4) The key is covered by or in contact with metal.
(5) Electric wave type keyless entry systems are being operated nearby.
(6) The key is placed near high-voltage, electric noise emitting equipment.
(7) Film with some metallic content is stuck to the back glass.
(d) Even if the key is in the vehicle exterior key detection area, the key may not operate properly due to the
vehicle body design.
(e) Even if the key is in the vehicle exterior key detection area, the key may not be properly detected if the
key is near a window, a door handle or the center of a bumper.
(f) Even if the key is in the vehicle interior key detection area, the key may not be properly detected if the key
is on the instrument panel, on the rear tray, in the glove box, on the floor, in a cup holder, etc.
(g) Depending on the way the key is held, the key may not operate properly.
4. 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.
(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
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
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 60 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 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
(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 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, in a cup holder, or in the glove box,
etc. the key reminder function may not operate and the key may be locked in the vehicle. Always carry
(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 doors from being unlocked by the
door oscillator (vehicle exterior) without the knowledge of the user. 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.
(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 the entry ignition function:
(1) To start the engine, first depress the (brake pedal) firmly until the engine switch indicator illuminates
(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
(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 turn the engine switch off before disconnecting the
battery cable. 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.
(e) 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:
Near the center of the tuner
Too close to the ground or in a high place
(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 built-in
battery. The life of the battery is approximately 1 to 2 years depending on the usage conditions. Also, if
the key is in contact with a cell phone while the user walks around (by putting them together into a
pocket, etc.), the battery may significantly deplete. 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 and using battery power, 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
(3) In order to communicate with the vehicle, the key is constantly checking for signals. Therefore if the key is in contact with a cell phone while the user walks around (by putting them together into a pocket,
etc.), the battery may significantly deplete.
(4) The key receives radio waves at approximately 134 kHz. If the key continuously receives strong,
identical frequency waves, this may drain the key battery. Store the key at least 1 m (3.28 ft.) from
TVs, personal computers, chargers for cell phone, etc. or other electrical products.
(5) When the door is being locked, the vehicle battery is used to transmit radio waves. The battery may be
fully depleted 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.
(6) 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.)).
(7) 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.
(8) When the battery is fully depleted and the engine does not start even after recharging, perform the
following: 1) move the shift lever to P; 2) turn the engine switch off; and 3) open and close the driver
door. Then start the engine.
(9) When starting the engine system after the removal and installation of the vehicle battery, first perform
the following: 1) open and close the driver door; and 2) wait 10 seconds or more. When an engine
system start is attempted after the above procedures, the engine system will not start. However, this is
not a malfunction. The engine system will start normally starting from the second attempt.
5. PRECAUTION FOR ECU AGGREGATION BOX
If the ECU aggregation box (certification ECU) and/or steering lock actuator (steering lock ECU) are
replaced, open and close the driver side door to record the current steering lock position into the
certification ECU. If this is not performed, the engine may not start.
