OPERATION CHECK
1. NOTICES WHEN CHECKING
(a) Wireless door lock/unlock function:
The wireless door lock control function operates only when the following conditions
are met:
(b) The operational area of the wireless transmitter differs depending on the
situation.
- The operational area differs depending on the user, the way the transmitter
is held and the location.
- In certain areas, the operational area will be reduced due to the vehicle
body shape and the influence of the surrounding environment.
- The weak electric waves from the transmitter may be affected if the
area has strong electric waves or noise. The operational area of the transmitter
may be reduced or the transmitter may not function.
- When the battery weakens, the operational area is reduced or the transmitter
may not function.
HINT:
The battery may weaken or other problems may occur if one of the following
occurs: 1) the transmitter has had prolonged exposure to direct sunlight,
such as on the instrument panel; or 2) the transmitter is placed within
1 m (3.28 ft) of electrical products, such as TVs, computers, cordless phones,
cell phone recharger stands (with the cell phone recharging), etc.

(c) Check the chattering prevention function:
- If a switch is pressed, check that the corresponding operation is performed
only once. If the switch is held down, check that the corresponding operation
occurs only once and does not repeatedly activate. Lastly, if a switch is
pressed at 1 second intervals, check that the corresponding operation activates
once for every press of the switch.

- When the lock switch is pressed, check that the hazard warning lights
flash once and the buzzer sounds once simultaneously with the locking operation
of all the doors.
- When the unlock switch is pressed once, check that the hazard warning
lights flash twice and the buzzer sounds twice simultaneously with the unlocking
operation of the driver side door.
(e) Check the automatic lock function:

- If the key is in the vehicle, check that the doors cannot be locked
by the lock switch. However, this does not apply when the system is in recognition

position) for 60 seconds by the theft alarm function when the panic switch
is held down for 0.8 seconds or more. Also, check that the horn stops sounding
and the lights stop flashing when any switch of the transmitter is pressed.
