radio antenna TOYOTA COROLLA HATCHBACK 2021 Owners Manual (in English)

1103-2. Opening, closing and locking the doors
COROLLA H/B_U• Cigarette boxes that have alumi-
num foil inside
• Metallic wallets or bags
• Coins
• Hand warmers made of metal
• Media such as CDs and DVDs
●When other wireless keys (that
emit radio waves) are being used
nearby
●When carrying the electronic key
together with the following devices
that emit radio waves
• Another vehicle’s electronic key or
a wireless key that emits radio
waves
• Personal computers or personal
digital assistants (PDAs)
• Digital audio players
• Portable game systems
●If window tint with a metallic con-
tent or metallic objects are
attached to the rear window
●When the electronic key is placed
near a battery charger or elec-
tronic devices
●When the vehicle is parked in a
pay parking spot where radio
waves are emitted
If the doors cannot be
locked/unlocked using the smart key
system, lock/unlock the doors by
performing any of the following:
●Bring the electronic key close to
either front door handle and oper-
ate the entry function.
●Operate the wireless remote con-
trol.
If the doors cannot be
locked/unlocked using the above
methods, use the mechanical key.
(  P.504)
If the engine cannot be started using
the smart key system, refer to
P.505.
■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 on the instru- ment panel, luggage cover 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 conditions, 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.

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.

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, some common reception
problems that probably do not
indicate a problem with the radio
are 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
audio/visual system:
• Be careful not to spill beverages over the audio/visual system.
