WARNING
■ General precautions while driving
Driving under the influence: Never drive your vehicle when unde r the influ-

Defensive driving: Always drive defensively. Anticipate mistake s that other
drivers or pedestrians might make and be ready to avoid acciden ts.
Driver distraction: Always give your full attention to driving. Anything that
distracts the driver, such as adjusting controls, talking on a cellular phone or
reading can result in a collision with resulting death or serio us injury to you,
your occupants or others.
■ General precaution regar ding children’s safety
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 p laying with
the windows, the moon roof, or other features of the vehicle. In addition,
heat build-up or extremely cold temperatures inside the vehicle can be fatal
to children.

Operation of each component
■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 ke y 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, th e 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 contro l 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 contro l. (P. 1 1 1 )
● The vehicle is locked/unlocked using the mechanical key. ( P. 503)

●Even when the electronic key is within the effective range (det ection 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 unl ocked.
• 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 w ave 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, th e 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 splashe s on the
door handle, such as in the rain or in a car wash when the elec tronic key is
within the effective range. (The doors will automatically be lo cked after
approximately 60 seconds if the doors are not opened and closed.)
● If the wireless remote control is used to lock the doors when t he electronic
key is near the vehicle, there is a possibility that the door m ay not be
unlocked by the smart key system. (Use the wireless remote cont rol 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 n ot be per-
formed. ( P. 124)

such medical devices.
Ask your Toyota dealer for details for disabling the entry func tion.

● Start the engine with the engine switch in ACCESSORY mode. The engine
may not start with the engine switch turned off. However, the e ngine will
operate normally from the second attempt.
● The engine switch mode is recorded by the vehicle. If the batte ry is recon-
nected, the vehicle will return the engine switch mode to the s tatus it was in
before the battery was disconnected. Make sure to turn off the engine
before disconnecting the battery. Take extra care when connecti ng the bat-
tery if the engine switch mode prior to discharge is unknown.
If the system will not start even after multiple attempts, cont act your Toyota
