can be opened. In order to pre-
vent theft, take all electronic keys
with you when leaving the vehicle.
●If the electronic key is put in the
trunk with all the doors locked, the
key may not be detected depend-
ing on the location of the key and
the surrounding radio wave condi-
tions. In this case, the key con-
finement prevention function
cannot be activated, causing the
doors to lock when the trunk is
closed. Make sure to check where
the key is before closing the trunk.
●The key confinement prevention
function cannot be activated if any
one of the doors is unlocked. In
this case, open the trunk using the
trunk opener.
■Internal trunk release lever
The trunk lid can be opened by pull-
ing up the glow-in-the-dark lever
located on the inside of the trunk lid.
The lever will continue to glow for
some time after the trunk lid is
closed.
■If the smart key system or the
wireless remote control does
not operate properly (if
equipped)
Replace the key battery with a new
one if it is depleted. ( P.458)

■Note for the entry function
●Even when the electronic key is
within the effective range (detec-
tion areas), the system may not
operate properly in the following
cases:
• The electronic key is too close to the window or outside door han-
dle, near the ground, or in a high
place when the doors are locked
or unlocked.
• The electronic key is near the ground or in a high place, or too
close to the center of the rear
bumper when the trunk is opened.
• The electronic key is on the instru- ment panel, rear package tray or
floor, or in the door pockets or
glove box when the engine is
started or engine switch modes
are changed.
●Do not leave the electronic key on
top of the instrument panel or near
the door pockets when exiting the
vehicle. Depending on the radio
wave reception co nditions, it may
be detected by the antenna out-
side the cabin and the door will
become lockable from the outside,
possibly trapping the electronic
key inside the vehicle.
●As long as the electronic key is
within the effective range, the
doors may be locked or unlocked
by anyone. However, only the
doors detecting the electronic key
can be used to unlock the vehicle.
●Even if the electronic key is not
inside the vehicle, it may be possi-
ble to start the engine if the elec-
tronic key is near the window.
●The doors may unlock or lock if a
large amount of water splashes on
the door handle, such as in the
rain or in a car wash when the
electronic key is within the effec-
tive range. (The doors will auto-
matically be locked after
approximately 60 seconds if the
doors are not opened and closed.)
●If the wireless remote control is
used to lock the doors when the
electronic key is near the vehicle,
there is a possibilit y that the door
may not be unlocked by the entry
function. (Use the wireless remote
control to unlock the doors.)
●Touching the door lock or unlock
sensor while wearing gloves may
prevent lock or unlock operation.
●When the lock operation is per-
formed using the lock sensor, rec-
ognition signals will be shown up
to two consecutive times. After
this, no recognition signals will be
given.
●If the door handle becomes wet
while the electronic key is within
the effective range, the door may
lock and unlock repeatedly. In that
case, follow the following correc-
tion procedures to wash the vehi-
cle:
• Place the electronic key in a loca-
tion 6 ft. (2 m) or more away from
the vehicle. (Take care to ensure
that the key is not stolen.)
• Set the electronic key to bat- tery-saving mode to disable the
smart key system. ( P.113)
●If the electronic key is inside the
vehicle and a door handle
becomes wet during a car wash, a
message may be shown on the
multi-information display and a
buzzer will sound outside the vehi-
cle. To turn off the alarm, lock all
the doors.
●The lock sensor may not work
properly if it co mes into contact
with ice, snow, mud, etc. Clean
the lock sensor and attempt to
operate it again.
●A sudden handle operation or a
handle operation immediately
after entering the effective range
may prevent the doors from being
unlocked. Touch the door unlock
sensor and check that the doors
are unlocked before pulling the
door handle again.

WARNING
■Caution regarding interfer-
ence with electronic devices
●People with implantable car-
diac pacemakers, cardiac
resynchronization ther-
apy-pacemakers or implantable
cardioverter defib rillators should
keep away from the smart key
system antennas. ( P. 1 1 1 )
The radio waves may affect the
operation of such devices. If
necessary, the entry function
can be disabled. Ask your Toy-
ota dealer for details, such as
the frequency of radio waves
and timing of the emitted radio
waves. Then, consult your doc-
tor to see if you should disable
the entry function.
●Users of any electrical medical
device other than implantable
cardiac pacemakers, cardiac
resynchronization ther-
apy-pacemakers or implantable
cardioverter defi brillators should
consult the manufacturer of the
device for information about its
operation under the influence of
radio waves.
Radio waves could have unex-
pected effects on the operation
of such medical devices.
Ask your Toyota dealer for details
on disabling the entry function.

3245-10. Tips for operating the audio/visual system
COROLLA_U
5-10.Tips for operating the audio/visual system
The use of a cellular phone inside or
near the vehicle may cause a noise
from the speakers of the
audio/visual system which you are
listening to. However, this does not
indicate a malfunction.
Usually, a problem with radio
reception does not mean there
is a problem with the radio  it
is just the normal result of condi-
tions outside the vehicle.
For example, nearby buildings
and terrain can interfere with FM
reception. Power lines or phone
wires can interfere with AM sig-
nals. And of course, radio sig-
nals have a limited range. The
farther the vehicle is from a sta-
tion, the weaker its signal will
be. In addition, reception condi-
tions change constantly as the
vehicle moves.
Here are some common recep-
tion problems that may not indi-
cate a problem with the radio as
described.
■FM
Fading and drifting stations:
Generally, the effective range of FM is about 25 miles (40 km).
Once outside this range, you
may notice fading and drifting,
which increase with the distance
from the radio transmitter. They
are often accompanied by dis-
tortion.
Multi-path: FM signals are
reflective, making it possible for
2 signals to reach the vehicle’s
antenna at the same time. If this
happens, the signals will cancel
each other out, causing a
momentary flutter or loss of
reception.
Static and fluttering: These
occur when signals are blocked
by buildings, trees or other large
objects. Increasing the bass
level may reduce static and flut-
tering.
Station swapping: If the FM sig-
nal being listened to is inter-
rupted or weakened, and there
is another strong station nearby
on the FM band, the radio may
tune in the second station until
the original signal can be picked
up again.
■AM
Fading: AM broadcasts are
reflected by the upper atmo-
sphere  especially at night.
These reflected signals can
interfere with those received
directly from the radio station,
causing the radio station to
sound alternately strong and
weak.

To avoid damage to the
