g.

The wireless door lock control operational area differs depending on the
situation.

i.

The operational area differs depending on the user and the ways the
transmitter is held.
In certain areas, the remote control function will only operate partially
for the operational area, which will be reduced due to the vehicle body shape
and the influence of the surrounding environment.
Since the transmitter uses faint radio waves, strong radio waves or
noise in the frequency used by the transmitter may reduce the operational
area and the remote control may not function.
When the battery is weakened, the operational area is reduced and the
remote control may not function.

ii.
iii.
iv.

HINT:
If the door control transmitter has been left in a place that is exposed to
direct sunlight, such as on the instrument panel, it may cause the battery to
be weakened or cause other related problems.

•

Register the recognition code when replacing the door control
transmitter or the door control receiver.
Add mode is used to register new recognition codes while still

retaining codes already registered. This mode is used when a new
transmitter is added. If the number of registered codes exceeds 4, the
previously registered codes will be erased in order, starting from the
first registered code.
Rewrite mode is used to erase all the previously registered
recognition codes in order to register all-new recognition codes. This
mode is used when the transmitter or the door control receiver is
replaced with a new one.
Confirmation mode is used to confirm how many recognition codes
have already been registered before another recognition code is
registered.
Prohibition mode is used to erase all the registered codes and disable
the wireless door lock function.
This mode is used when the transmitter is lost.
All the following registration procedures must be performed in order.

order to register new recognition codes. This mode is used when the transmitter
or the door control receiver is replaced with a new one.
Confirmation Mode is used to confirm how many recognition codes have already
been registered before any additional recognition codes are registered.

Prohibition Mode is used to erase all the registered codes and disable the wireless
door lock function. This mode is used when the transmitters are lost.

z In Confirmation Mode, LOCK-UNLOCK operation will occur once for each
recognition code that has been registered. For example, if 2 recognition codes
have been registered, the LOCK-UNLOCK operation will occur twice.
z In Confirmation Mode, if no recognition codes have been registered, LOCKUNLOCK operation will occur 11 times.
z If Confirmation Mode or Prohibition Mode is selected, the operation ends after
the response to the selected mode is completed.
g. Register a new recognition code (Add Mode or Rewrite Mode) in accordance with the
following procedure.
i. Within 45 seconds of Add Mode or Rewrite Mode being selected, press the LOCK and
