specifically for vehicles of the
same model and model year as
your vehicle. Fix them securely
in place onto the carpet.
1Insert the retaining hooks
(clips) into the floor mat eye-
lets.
2 Turn the upper knob of each
retaining hook (clip) to secure
the floor mats in place.
Always align the marks . The shape of the retaining hooks
(clips) may differ from that shown in
the illustration.
Before driving
Observe the following
before starting off in the
vehicle to ensure safety of
driving.
Installing floor mats
WARNING
Observe the following precau-
tions.
Failure to do so may cause the
driver’s floor mat to slip, possibly
interfering with t
he pedals while
driving. An unexpectedly high
speed may result or it may
become difficult to stop the vehi-
cle. This could lead to an acci-
dent, resulting in death or serious
injury.
■When installing the driver’s
floor mat
●Do not use floor mats designed
for other models or different
model year vehicles, even if
they are Toyota Genuine floor
mats.
●Only use floor mats designed
for the driver’s seat.
●Always install the floor mat
securely using the retaining
hooks (clips) provided.
●Do not use two or more floor
mats on top of each other.
●Do not place the floor mat bot-
tom-side up or upside-down.

671-2. Child safety
Owners Manual_USA_M0C052_en
1
For safety and security
WARNING
●When installing a child restraint
system in the rear center seat,
adjust both seat cushions to the
same position and align both
seatbacks at the same angle.
Otherwise, the child restraint
system cannot be securely
restrained and t his may cause
death or serious injuries in the
event of sudden braking, sud-
den swerving or an accident.
●If the seat is adjusted, reconfirm
the security of the child restraint
system.
■When installing a booster
seat
To prevent the belt from going into
ALR lock mode, do not fully
extend the shoulder belt. ALR
mode causes the belt to tighten
only. This could cause injury or
discomfort to the child. ( P.31,
33)
■Do not use a seat belt
extender
If a seat belt extender is used
when installing a child restraint
system, the seat belt will not
securely hold the child restraint
system, which could cause death
or serious injury to the child or
other passengers in the event of
sudden braking, sudden swerv-
ing or an accident.

■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.527)
●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 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.
■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.
• The electronic key is on the instru- ment panel, or floor, or in the door
pockets or glove box when the
hybrid system 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
doors detecting the electronic key
can be used to unlock the vehicle.
●Even if the electro nic key is not
inside the vehicle, it may be possi-
ble to start the hybrid system if the
electronic 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

1313-2. Opening, closing and locking the doors and tailgate

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 possib ility that the door
may not be unlocke d by the entry
function. (Use the wireless remote
control to unloc k the doors.)
●Touching the door lock sensor
while wearing gloves may delay or
prevent lock operation.
●When the lock op eration is per-
formed using the lock sensor, rec-
ognition signals will be shown up
to two consecutive times. After
this, no recogniti on signals will be
given.
●If the door handle becomes wet
while the electronic key is within
the effective ran ge, the door may
lock and unlock repeatedly. In this
case, follow the fo llowing 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 battery-
saving mode to disable the smart
key system. ( P.129)
●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-informatio n 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 com es into contact
with ice, snow, mud, etc. Clean
the lock sensor and attempt to
operate it again.
●A sudden approach to the effec-
tive range or door handle may pre-
vent the doors from being
unlocked. In this case, return the
door handle to the original position
and check that the doors unlock
before pulling the door handle again.
●If there is another electronic key in
the detection area, it may take
slightly longer to unlock the doors
after the door handle is gripped.
■When the vehicle is not driven
for extended periods
●To prevent theft of
the vehicle, do
not leave the electronic key within
6 ft. (2 m) of the vehicle.
●The smart key system can be
