INFORMATION
If you close the trunk lid while an electronic key is left
in the trunk and all doors are locked, an alarm should
be activated. However, if the electronic key is placed
near the spare tire or at the edge of the trunk, or if the
electronic key is in a metallic bag, the trunk lid might
not be unlocked.
 If you accidentally lock an electronic key in the trunk
when all doors are locked, be aware that anyone can
unlock the trunk by pushing the trunk button.
 Even when the electronic key is outside the trunk, an
alarm still might be activated if the electronic key is
near the trunk. However, if you have the electronic
key, there is no problem.
BATTERY POWER SAVING
If the electronic key is left within the effective range of the
outside of the vehicle for more than 10 minutes without locking
or unlocking the doors, the entry function is disabled.
If the electronic key does not enter the effective range of the
outside of the vehicle for 4 days, the output interval of the
electromagnetic signal is extended. If this situation continues
for 14 days, the entry function is disabled.
To reactivate the entry function properly, perform any of the
following:
(a) Press the lock button on the outside door handle while
carrying the electronic key.
(b) Perform a wireless remote control function.
(c) Insert and turn the mechanical key in the keyhole of the
door.

INFORMATION
To maintain communication with the vehicle,
electronic keys use builtin battery power. The
battery service life is about 1 to 2 years on average.
If battery power becomes insufficient, replace the
battery with a new one.
 The electronic key continually receives
electromagnetic waves, and if it receives strong
electromagnetic waves over a period of time, the
battery can be drastically run down. Therefore, avoid
storing electronic keys near any electrical
appliances.
Here is a list of electrical appliances which may have
adverse effects on the electronic key performance:
TVs, personal computers, cellular phone or cordless
phone recharger units, electric light stands and
fluorescent desk lights
Note that you should always keep such electrical
appliances at least 1 m (3 ft.) away from the electronic
key.
