Safety information for children
●It is recommended that children sit in the rear seats to avoid acci-
dental contact with the shift lever, wiper switch etc.
● Use the sliding door child-protector lock or the window lock switch
to avoid children opening the door while driving or operating the
power window accidentally. ( P. 125, 183)
● Do not let small children operate equipment which may catch or
pinch body parts, such as the power window, hood, back door,
seats etc.
Observe the following precautions when children are in the vehi-
cle.
Use a child restraint system appropriate for the child, until the
child becomes large enough to properly wear the vehicle’s seat
belt.
WARNING
Never leave children unattended in the vehicle, and never allow children to
have or use the key.
Children may be able to start the vehicle or shift the vehicle into neutral.
There is also a danger that children may injure themselves by playing with
the windows, the moon roof (if equipped) or other features of the vehicle. In
addition, heat build-up or extremely cold temperatures inside the vehicle
can be fatal to children.

Exhaust gas precautions
Harmful substance to the human body is included in exhaust
gases if inhaled.
WARNING
Exhaust gases include harmful carbon monoxide (CO), which is colorless and
odorless. Observe the following precautions.
Failure to do so may cause exhaust gases enter the vehicle and may lead to
an accident caused by light-headedness, or may lead to death or a serious
health hazard.
■Important points while driving
● Keep the back door closed.
● If you smell exhaust gases in the vehicle even when the back door is
closed, open the windows and have the vehicle inspected at your Toyota
dealer as soon as possible.
■ When parking
● If the vehicle is in a poorly ventilated area or a closed area, such as a
garage, stop the engine.
● Do not leave the vehicle with the engine on for a long time.
If such a situation cannot be avoided, park the vehicle in an open space
and ensure that exhaust fumes do not enter the vehicle interior.
● Do not leave the engine running in an area with snow build-up, or where it
is snowing. If snowbanks build up around the vehicle while the engine is
running, exhaust gases may collect and enter the vehicle.
■ Exhaust pipe
The exhaust system needs to be checked periodically. If there is a hole or
crack caused by corrosion, damage to a joint or abnormal exhaust noise, be
sure to have the vehicle inspected and repaired by your Toyota dealer.

WARNING
■To prevent an accident
Observe the following precautions while driving.
Failure to do so may cause a door to open unexpectedly and an occupant to
fall out of the vehicle, resulting in death or serious injury.
● Ensure that all doors are properly closed and locked.
● Set the sliding door child-protector locks when children are seated in the
vehicle.
● Do not operate the inside handle of the doors while driving.
■ When children are in the vehicle
Observe the following precautions.
Failure to do so may result in death or serious injury.
● Do not leave children alone in the vehicle.
If a child is accidentally locked in the vehicle, they could have heat
exhaustion or other injuries.
● Do not allow a child to open or close the sliding door.
Doing so may cause the sliding door to move unexpectedly, or cause the
child’s hands, head, or neck to be caught by the moving sliding door.
■ Operating the sliding doors
Observe the following precautions.
Failure to do so may cause parts of the body to be caught, resulting in death
or serious injury.
● When opening or closing a sliding door, thoroughly check to make sure the
surrounding area is safe.
● When opening or closing the sliding doors with windows open, keep all
body parts clear of the windows.
● If anyone is in the vicinity, make sure they are safe and let them know that
the sliding door is about to open or close.
● Do not leave the sliding door at half-opened position because the sliding
door is not latched at this position. The sliding door may move unexpect-
edly on an incline.

3-2. Opening, closing and locking the doors
■Battery-saving function
In the following circumstances, the entry function is disabled in order to pre-
vent the vehicle battery from discharging and the electronic key battery from
discharging.
●When the entry function has not been used for 5 days or more
● When the electronic key has been left within approximately 6 ft. (2 m) of the
vehicle for 10 minutes or more
● If the entry function has not been used for 14 days or more, the vehicle can-
not be unlocked by a door other than the driver’s door. To unlock the vehicle,
grip the driver’s door handle or use the wireless remote control or the
mechanical key.
The system will resume operation when...
● The vehicle is locked using the lock sensor when carrying the electronic key
on your person.
● The vehicle is locked/unlocked using the wireless remote control. ( P. 1 1 1 )
● The vehicle is locked/unlocked using the mechanical key. ( P. 581)
■ Conditions affecting operation
P. 1 1 9
■ Notes for the entry function
●Even when the electronic key is within the effective range (detection areas),
the system may not operate properly in the following cases.
• The electronic key is too close to the window or outside door handle, near
the ground, or in a high place when the doors are locked or unlocked.
• The electronic key is on the instrument panel, floor or in the 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 recep-
tion conditions, it may be detected by the antenna outside 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 elec-
tronic key can be used to unlock the vehicle.
● 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 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 possibility that the door may not be
unlocked by the smart key system. (Use the wireless remote control to
unlock the doors.)
● If power slide door is unable to operate due to prohibition by the power slid-
ing door main switch, the door unlock and open operation will not be per-
formed. ( P. 124)
