■To prevent an accident
Ensure that both side doors are prop-
erly closed while driving the vehicle. Failure to do so may result in a door
opening and an occupant being
thrown out of the vehicle, resulting in death or serious injury.
■When opening or closing a door
Check the surroundings of the vehicle
such as whether the vehicle is on an
incline, whether there is enough space for a door to open and whether
a strong wind is blowing. When open-
ing or closing the door, hold the door handle tightly to prepare for any
unpredictable movement.
■Side window open/close function
linked to door operation
Do not hold the upper edge of the side window when you close the door.
Otherwise, your fingers or hand may

1063-2. Opening, closing and locking the doors and trunk
Trunk
The trunk can be opened using
the trunk opener switch, entry
function or wireless remote
control.
WA R N I N G
Observe the following precautions.
Failure to do so may result in death or
serious injury.
■Before driving
●Make sure that the trunk lid is closed before driving. If not fully
closed, while driving, it may open
unexpectedly, hit near-by objects, or luggage may fall out, possibly
leading to an accident.
Also, exhaust gasses may enter the vehicle, possibly leading to death or
a serious health hazard.
●Do not allow children to play in the
trunk.
If a child is accidentally locked in the trunk, they could suffer from
heat exhaustion, suffocation or
other injuries.
●Do not allow a child to open or
close the trunk lid. Doing so may cause the trunk lid to
open unexpectedly, or cause the
child’s hands, head, or neck to be caught by the closing trunk lid.
■Important points while driving
Never let anyone sit in the trunk. In
the event of sudden braking or a colli-
sion, they are susceptible to death or serious injury.
■Using the trunk
Observe the following precautions.
Failure to do so may cause parts of
the body to be caught, resulting in serious injury.
●Remove any heavy loads, such as snow and ice, from the trunk lid
before opening it. Failure to do so
may cause the trunk lid to suddenly shut again after it is opened.
●Be careful not to come into contact with the exhaust gasses when
opening or closing the trunk. If the
engine is running, there is a risk of being burned by the exhaust
gasses.
●When opening or closing the trunk
lid, thoroughly check to make sure
the surrounding area is safe.
●If anyone is in the vicinity, make
sure they are safe and let them know that the trunk is about to open
or close.
●Use caution when opening or clos-
ing the trunk lid in windy weather as
it may move abruptly in strong wind.
●The trunk lid may suddenly shut if it
is not opened fully. It is more diffi- cult to open or close the trunk lid on
an incline than on a level surface,
so beware of the trunk lid unexpect- edly opening or closing by itself.
Make sure that the trunk lid is fully
open and secure before using the trunk.

1123-2. Opening, closing and locking the doors and trunk
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 recep-
tion conditions, it may be detected by
the antenna outside the cabin and the doors will become lockable from the
outside, possibly trapping the elec-
tronic key inside the vehicle.
●As long as the electronic key is within
the effective range, the doors may be locked or unlocked by anyone. How-
ever, 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 possible to start
the engine 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 effective range. (The doors will automatically be locked after
approximately 30 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 pos-
sibility 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 sen-
sor while wearing gloves may prevent
lock or unlock operation.
●Vehicles without a double locking sys-
tem: When the lock operation is per-
formed using the lock sensor, recognition signals will be shown up to
three consecutive times. After this, no
recognition signals will be given.
●If the door handle becomes wet while
the electronic key is within the effec- tive range, the door may lock and
unlock repeatedly. In this case, follow
the following correction procedures to
wash the vehicle:
• Place the electronic key in a location 2 m (6 ft.) or more away from the vehi-
cle. (Take care to ensure that the key
is not stolen.) • Set the electronic key to battery-sav-
ing mode to disable the smart entry &
start system. ( P. 1 1 1 )
●If the electronic key is inside the vehi-
cle and a door handle becomes wet during a car wash, a message may be
shown on the multi-information dis-
play and a buzzer will sound outside the vehicle. To turn off the alarm, lock
both side doors.
●The lock sensor may not work prop-
erly if it comes into contact with ice,
snow, mud, etc. Clean the lock sensor and attempt to operate it again.
●A sudden handle operation or a han-dle operation immediately after enter-
ing 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.
●Unlocking the vehicle may take more
time if another electronic key is within the effective range.
■When the vehicle is not driven for
extended periods
●To prevent theft of the vehicle, do not
leave the electronic key within 2 m (6
ft.) of the vehicle.
●The smart entry & start system can be
deactivated in advance. ( P. 1 1 3 )
●Setting the electronic key to bat-
tery-saving mode helps to reduce key battery depletion. ( P. 1 1 1 )
■To operate the system properly
●Make sure to carry the electronic key
when operating th e system. Do not get the electronic key too close to the
vehicle when operating the system
from the outside of the vehicle.
Depending on the position and holding
condition of the electronic key, the key may not be detected correctly and the

using the same number as on your
license plate or other simple codes.
●To use 0 as a digit, press the trunk
opener switch 10 times.
●If a mistake is made during registra-
tion, unlock the doors or trunk using
the wireless remote control to cancel registration. Then perform registra-
tion again, starting from step 1. How-
ever, if the mistake was made in step 10 , a buzzer will sound and step 10
can be performed again.
●To clear the PIN code, perform the
registration procedure and enter
22222.
●After registering a new PIN code,
make sure to check that the doors can be unlocked using the code.
●If the smart entry & start system has
been disabled using the wireless
remote control method, the PIN code for the PIN code smart entry cannot
be cleared. ( P.114)
●In the following cases, perform the
PIN code registration procedure
again. • If the PIN code has been forgotten.
• When you wish to change the PIN
code.
●Make sure to change the PIN code
periodically.
●If the vehicle has been loaned to
another person, make sure that the PIN code has not been changed or
cleared. If the PIN code has been
changed or cleared, perform PIN code registration again.
■Unlocking method
●If an electronic key is within a detec-tion area, operation of the smart entry
will be given priority.
●If a mistake is made while entering the
PIN code, wait 5 seconds or more
before performing the procedure again.
●If the incorrect PIN code is entered 5 times consecutively, a buzzer will
sound for approximately 2 seconds
and operation will not be possible for 5 minutes.

1344-1. Before driving
WA R N I N G
●Vehicles with an automatic trans-
mission: Be careful not to shift the
shift lever with the accelerator pedal depressed. Shifting the shift
lever to a gear other than P or N
may lead to unexpected rapid acceleration of the vehicle that may
cause an accident and result in
death or serious injury.
●Do not place items in the shift
lever's surrounding area. It may
cause incorrect operation.
●If the shift boot is pulled out during
cleaning, return it to its previous position. If the shift boot is left
pulled out, the shift lever may
become difficult to operate.
■If you hear a squealing or scrap-
ing noise (brake pad wear indica- tors)
Have the brake pads checked and
replaced by any authorized Toyota retailer or Toyota authorized repairer,
or any reliable repairer as soon as
possible. Rotor damage may result if the pads are not replaced when
needed.
It is dangerous to drive the vehicle when the wear limits of the brake
pads and/or those of the brake discs
are exceeded.
■When the vehicle is stopped
●Do not race the engine. If the vehicle is in any gear other
than P (automatic transmission) or
N, the vehicle may accelerate sud- denly and unexpectedly, causing an
accident.
●Vehicles with an automatic trans-
mission: In order to prevent acci-
dents due to the vehicle rolling away, always keep depressing the
brake pedal while the engine is run-
ning, and apply the parking brake as necessary.
●If the vehicle is stopped on an incline, in order to prevent acci-
dents caused by the vehicle rolling
forward or backward, always depress the brake pedal and
securely apply the parking brake as
needed.
●Avoid revving or racing the engine.
Running the engine at high speed while the vehicle is stopped may
cause the exhaust system to over-
heat, which could result in a fire if combustible material is nearby.
■When the vehicle is parked
●Do not leave glasses, cigarette
lighters, spray cans, or soft drink
cans in the vehicle when it is in the sun.
Doing so may result in the follow-
ing:
• Gas may leak from a cigarette
lighter or spray can, and may lead
to a fire.
• The temperature inside the vehicle
may cause the plastic lenses and plastic material of glasses to
deform or crack.
• Soft drink cans may fracture, caus-
ing the contents to spray over the
interior of the vehicle, and may also cause a short circuit in the vehicle’s
electrical components.
●Do not leave cigarette lighters in the
vehicle. If a cigarette lighter is in a
place such as the glove box or on the floor, it may be lit accidentally
when luggage is loaded or the seat
is adjusted, causing a fire.
●Do not attach adh esive discs to the
windshield or windows. Do not
place containers such as air fresh- eners on the instrument panel or
dashboard. Adhesive discs or con-
tainers may act as lenses, causing a fire in the vehicle.

WA R N I N G
●Do not leave a door or window
open if the curved glass is coated
with a metallized film such as a sil- ver-colored one. Reflected sunlight
may cause the glass to act as a
lens, causing a fire.
●Always apply the parking brake,
shift the shift lever to P (vehicles
with an automatic transmission), stop the engine and lock the vehi-
cle.
Do not leave the vehicle unat- tended while the engine is running.
If the vehicle is parked with the shift
lever in P but the parking brake is not set, the vehicl e may start to
move, possibly leading to an acci-
dent.
●Do not touch the exhaust pipes
while the engine is running or immediately after turning the engine
off.
Doing so may cause burns.
■When taking a nap in the vehicle
Always turn the engine off. Otherwise, if you accidentally move the shift lever
or depress the accelerator pedal, this
could cause an accident or fire due to engine overheating. Additionally, if the
vehicle is parked in a poorly ventilated
area, exhaust gases may collect and enter the vehicle, leading to death or
a serious health hazard.
■When braking
●When the brakes are wet, drive
more cautiously. Braking distance increases when
the brakes are wet, and this may
cause one side of the vehicle to brake differently than the other
side. Also, the parking brake may
not securely hold the vehicle.
●If the brake booster device does not operate, do not follow other vehi-
cles closely and avoid hills or sharp
turns that require braking. In this case, braking is still possible,
but the brake pedal should be
depressed more firmly than usual. Also, the braking distance will
increase. Have your brakes fixed
immediately.
●Do not pump the brake pedal if the
engine stalls. Each push on the brake pedal uses
up the reserve for the
power-assisted brakes.
●The brake system consists of 2 indi-
vidual hydraulic systems; if one of the systems fails, the other will still
operate. In this case, the brake
pedal should be depressed more firmly than usual and the braking
distance will increase. Have your
brakes fixed immediately.
■If the vehicle becomes stuck
Do not spin the wheels excessively when any of the tires is up in the air,
or the vehicle is stuck in sand, mud,
etc. This may damage the driveline components or propel the vehicle for-
ward or backward, causing an acci-
dent.
NOTICE
■Pre-driving check
Trapping small animals in the cooling
fan and belts of the engine may result
in a malfunction. Check that no small animal enters the engine compart-
ment and under the vehicle before
starting the engine.

1384-1. Before driving
WA R N I N G
●Do not place cargo or luggage in or
on the following locations as the
item may get under the clutch (manual transmission), brake or
accelerator pedal and prevent the
pedals from being depressed prop- erly, block the driver’s vision, or hit
the driver or passengers, causing
an accident:
• At the feet of the driver
• On the front passenger or rear
seats (when stacking items)
• On the package tray
• On the instrument panel
• On the dashboard
●Secure all items in the occupant
compartment, as they may shift and injure someone during sudden
braking, sudden swerving or an
accident.
■Load and distribution
●Do not overload your vehicle.
●Do not apply loads unevenly.
Improper loading may cause deteri- oration of steering or braking con-
trol which may cause death or
serious injury.
Trailer towing
Toyota does not recommend
towing a trailer with your vehi-
cle. Toyota also does not rec-
ommend the installation of a
tow hitch or the use of a tow
hitch carrier for a wheelchair,
scooter, bicycle, etc. Your vehi-
cle is not designed for trailer
towing or for the use of tow
hitch mounted carriers.
