Key reminder alarm
If you push the lock button on the outside door handle
with an electronic key left in the vehicle, an alarm sounds

the electronic key.
INFORMATION
 Do not put an electronic key on the instrument panel,
rear package tray or floor, or in the glove box or

a certain distance away from the window or outside
door handle and then push the lock button again.
 If the electronic key is left in the vehicle, attempting
to lock the door by pushing in the lock button located
in the inside door handle and closing the door will
unlock all the doors and activate the alarm for 2

22UNLOCKING THE DOOR(S) WITH ENTRY FUNCTION
G11032
When you take hold the back side of the outside door
handle on the driver’s door carrying an electronic key, the
driver’s door will be unlocked. When you take hold the
back
side of the outside door handle except on the driver’s
door, carrying an electronic key, all the doors will be
unlocked. At this time, two beeps will sound and turn
signal lights flash twice.
When you get close to your vehicle (about 1 m (3 ft.) from each
outside door handle), and are carrying the electronic key, the
electronic code emitted from the key is automatically checked
to determine if it corresponds to the registered ID code for the
vehicle. After this, the outer foot lights come on. (For outer foot
lights, see “Outer foot lights” on page 208.)
You can select the doors to be unlocked. For details, see
“Changing the doors to be unlocked” on page 23. When the door(s) is(are) unlock

for 15 seconds if the interior light switch is in the “DOOR”
position. However, the interior lights go out when you push the
power door lock switch in the lock position or select the engine
switch in “ACC” or “IG− ON” mode. For further information, see
“Interior lights” on page 98.
You have 30 seconds to open a door after operating the
unlocking function. If a door is not opened by then, all the doors
will be automatically locked again.
INFORMATION
 When unlocking the door(s), be sure to take hold of
the back side of the outside door handle firmly as
shown in the illustration. Taking hold of the handle
with a gloved hand might cause a delay in unlocking
or may not unlock.
 When you take hold of the handle to unlock the

been unlocked. If the turn signal lights flash twice,
two beeps sound outside the vehicle, the doors are
unlocked. At this time, you can pull the outside door
handle to open the door. If you quickly move closer
to the vehicle or pull the outside door handle quickly,
the doors might not unlock. If you cannot open the
door by pulling the outside door handle at this time,
push it back to the original position and then pull it
out again.

 If a large amount of water is applied to the outside
door handle during heavy rain or a car wash, and
someone carrying an electronic key is near the

all the doors will be unlocked.
INFORMATION
If you get in the vehicle from the driver’s door using an

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.

KEYS AND DOORS
26BATTERY 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.

of the electronic key about 10 mm (0.4 in.) over the engine
