1384-2. Opening, closing and locking the doors and trunk
Owners Manual_USA_M62064_en
●Electronic keys that will not be
used for long periods of time can
be set to the battery-saving mode
in advance.
■Conditions affecting operation
The smart key system uses weak
radio waves. In the following situa-
tions, the communication between
the electronic key and the vehicle
may be affected, preventing the
smart key system, wireless remote
control and immobilizer system from
operating properly. (Ways of coping:
 P.482)
●When the electronic key battery is
depleted
●Near a TV tower, electric power
plant, gas station , radio station,
large display, airpo rt or other facil-
ity that generates strong radio
waves or electrical noise
●When carrying a portable radio,
cellular phone, cordless phone or
other wireless communication
device
●When the electronic key is in con-
tact with, or is covered by the fol-
lowing metallic objects
• Cards to which al uminum foil is
attached
• 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 electronic key or a wire- less key that emits radio waves
• Personal computers or personal digital assistants (PDAs)
• Digital audio players
• Portable game systems
●If window tint wit h 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.
■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 fuel cell sys-
tem is started or power 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 doors 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

*: Vehicles with Toyota Teammate
Advanced Drive, r efer to “Toyota
Teammate Advanced Drive
OWNER’S MANUAL”.
While driving on a road with
clear white (yellow) lane lines,
the LTA system warns the driver
if the vehicle may deviate from
the current lane or course
*, and
also can slightly operate the
steering wheel to help avoid
deviation from the lane or
course
*. Also, while the dynamic
radar cruise control with full-
speed range is operating, this
system will operate the steering
wheel to maintain the vehicle’s
lane position.
The LTA system recognizes
white (yellow) lane lines or a
course
* using the front camera.
Additionally, it detects preceding
vehicles using the front camera
and radar.

■Lane departure alert func-
tion
When the system determines
that the vehicle might depart
from its lane or course
*, a warn-
ing is displayed on the multi-

alert the driver.
When the warning buzzer sounds
or the steering wheel vibrates,
check the area around your vehicle
and carefully operate the steering
wheel to move the vehicle back to
the center of the lane.
Vehicle with BSM: When the sys-
tem determines that the vehicle

alert will operate e ven if the turn
signals are operating.
*: Boundary between asphalt and the side of the road, such as
grass, soil, or a curb
■Steering assist function
When the system determines
that the vehicle might depart
from its lane or course
*, the sys-
tem provides assistance as nec-
essary by operating the steering
wheel in small amounts for a
short period of time to keep the
vehicle in its lane.
Vehicle with BSM: When the sys-
tem determines that the vehicle
might depart from its lane and that
the possibility of a collision with an
overtaking vehicle in the adjacent
lane is high, the steering assist
function will operate even if the turn
signals are operating.

*: Compatible portable devices and the wireless charger contain
charging coils. The charging coil
inside the wireless charger can move within the area around the
center of the charging tray.
When the charging coil inside a
portable device is detected within
the charging area, the charging
coil in the wirel
ess charger will
move near the other coil and
charging will begin. If the
charging coil inside the portable
device is moved out of the
charging area, charging will be
stopped automatically.
Additionally, if 2 or more portable
devices are placed on the
charging tray at t he same time,
each charging coil may not be
detected correctly and charging
may not be possible.
■Using the wireless charger
1 Press the power supply
switch of the wireless char-
ger.
Switches on and off with each
press of the power supply switch.
When turned on, the operation indi-
cator light (green) comes on.
Even with the fuel cell system off,
the on/off state of the power supply
switch is memorized.

Depending on the portable device,
its charging coil may not be in the
center of the device. In this case,
place the portable device so that its
charging coil is centered in the
charging area.
While charging, the operation indi-
cator light (orang e) will be illumi-
nated.
If charging does not begin, move
the portable device as close to the
center of the charging area as pos-
sible.
If charging is not performed, the
operation indicator light will slowly
illuminate in gr een and orange
alternatively and a sound of
charging coil operation may be
heard repeatedly.
When charging is complete, the
operation indicator light (green)
comes on.
■Recharging function
 When charging is complete
and after a fixed time in the
charge suspension state,
charging restarts.
 If a portable device is moved
significantly within the
charging area, the charging
coil may disconnect and
charging may temporarily be
stopped. However, if a
charging coil is detected within the charging area, the
charging coil inside the wire-
less charger will move near
the other coil and charging
will resume.
■Lighting conditions of oper-
ation indicator light
*1: While in standby, charging power
is not output. If a metal object is
placed on the charging tray in
this state, the object will not heat
up.
*2: Depending on the portable device, there are cases where
the operation indicator light will
continue being lit up orange even
after the charging is complete.

Maintenance and care
●To protect the paint from damage,
make sure to obs erve the follow-
ing precautions.
• Do not use acidi c, alkaline or
abrasive detergent
• Do not use hard brushes
• Do not use det ergent on the
wheels when they are hot, such
as after driving or parking in hot
weather
■Brake pads and calipers
Rust may form if the vehicle is
parked with wet brake pads or disc
rotors, causing them to stick. Before
parking the vehicle after it is
washed, drive slow ly and apply the
brakes several times to dry the
parts.
■Bumpers
Do not scrub with abrasive cleaners.
■Front side windows water-
repellent coating
●The following precautions can
extend the effectiveness of the
water-repellent coating.
• Remove any dirt, etc. from the front side windows regularly.
• Do not allow dirt and dust to accu- mulate on the windows for a long
period.
Clean the windows with a soft,
damp cloth as soon as possible.
• Do not use wax or glass cleaners
that contain abrasives when
cleaning the windows.
• Do not use any metallic objects to
remove condensation build up.
■Plated portions
If dirt cannot be removed, clean the
parts as follows:
●Use a soft cloth dampened with an
approximately 5% solution of neu-
tral detergent and water to clean
the dirt off.
●Wipe the surface with a dry, soft
cloth to remove any remaining
moisture.
●To remove oily deposits, use alco-
hol wet wipes or a similar product.
■Roof film (vehicles with elec-
tronic sunshade)
●Dirt like bird droppings and oil
should be cleaned off with a neu-
tral detergent immediately.
●When something was attached on
the film and its mark remains. The
small mark can be recovered by
dryer heating.
●Do not apply any films on the film.
●Do not use wax that contains
abrasives.
●In case of the film repair, please
request at your Toyota dealer.
