YARIS_F_OM_Europe_OM52A54E■Electronic key battery-saving function
■Conditions affecting operation
The smart entry & start 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 entry & start system, wireless remote control
and engine immobilizer system from operating properly.
(Ways of coping: P. 631)
●When the electronic key battery is depleted
●Near a TV tower, electric power plant, gas station, radio station, large dis-
play, airport or other facility 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 contact with, or is covered by the following
metallic objects
• Cards to which aluminum foil is attached
• Cigarette boxes that have aluminum 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
• Portable radio, cellular phone, cordless phone or other wireless commu-
nication device
• Another vehicle’s electronic key or a wireless key that emits radio waves
• Personal computers or personal digital assistants (PDAs)
• Digital audio players
• Portable game systems When battery-saving mode is set, battery
depletion is minimized by stopping the
electronic key from receiving radio waves.
Press twice while pressing and hold-
ing . Confirm that the electronic key
indicator flashes 4 times.
While the battery-saving mode is set, the
smart entry & start system cannot be
used. To cancel the function, press any of
the electronic key buttons.

Operation of each component
YARIS_F_OM_Europe_OM52A54E●If window tint with a metallic content or metallic objects are attached to the
rear window
●When the electronic key is placed near a battery charger or electronic
devices
■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 near the ground or in a high place, or too close to
the rear bumper center when the back door is opened.
• The electronic key is on the instrument panel, luggage cover (if equipped)
or floor, or in the door pockets, glove box, accessory box of the instru-
ment panel, or in/near the front cup holder 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.
●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 if a large amount of water splashes on the door han-
dle, such as in the rain or in a car wash when the electronic key is within the
effective range. (The door 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 possibility 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 sensor while wearing gloves may prevent
lock or unlock operation.
●When the lock operation is performed using the lock sensor, recognition sig-
nals will be shown up to two 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 that 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
vehicle. (Take care to ensure that the key is not stolen.)
• Set the electronic key to battery-saving mode to disable the smart entry &
start system. (→P. 170)

■If the engine does not start
The engine immobilizer system may not have been deactivated. ( P. 85)
Contact any authorized Toyota retailer or Toyota authorized repairer, or any
reliable repairer.
■ When the steering lock cannot be released
■ Key reminder function
A buzzer sounds if the driver’s door is opened while the engine switch is in
the “LOCK” or “ACC” position to remind you to remove the key.
When starting the engine, the engine
switch may seem stuck in the “LOCK”
position. To free it, turn the key while turn-
ing the steering wheel slightly left and
right.
WARNING
■ When starting the engine
Always start the engine while sitting in the driver’s seat. Do not depress the
accelerator pedal while starting the engine under any circumstances.
Doing so may cause an accident resulting in death or serious injury.
■ Caution when driving
Do not turn the engine switch to the “LOCK” position while driving. If, in an
emergency, you must turn the engine off while the vehicle is moving, turn
the engine switch only to the “ACC” pos ition to stop the engine. An accident
may result if the engine is stopped while driving. ( P. 569)
NOTICE
■To prevent battery discharge
Do not leave the engine switch in the “ACC” or “ON” position for long peri-
ods of time without the engine running.
■ When starting the engine
● Do not crank the engine for more than 30 seconds at a time. This may
overheat the starter and wiring system.
● Do not race a cold engine.
● If the engine becomes difficult to start or stalls frequently, have your vehi-
cle checked by any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer immediately.

■Auto power off function
Vehicles with a Multidrive
If the vehicle is left in ACCESSORY or IGNITION ON mode (the engine is
not running) for more than an hour with the shift lever in P, the engine
switch will automatically turn off. However, this function cannot entirely pre-
vent battery discharge. Do not leave the vehicle with the engine switch in
ACCESSORY or IGNITION ON mode for long periods of time when the
engine is not running.
Vehicles with a manual transmission
If the vehicle is left in ACCESSORY or IGNITION ON mode (the engine is
not running) for more than an hour, the engine switch will automatically turn
off. However, this function cannot entirely prevent battery discharge. Do not
leave the vehicle with the engine switch in ACCESSORY or IGNITION ON
mode for long periods of time when the engine is not running.

a frontal collision with a vehicle is high.
Each function is operational at the following speeds:
●Pre-crash warning:
• Vehicle speed is approximately 15 to 140 km/h (10 to 85 mph).
• The relative speed between your vehicle and a preceding vehicle is
approximately 15 km/h (10 mph) or more.

• The relative speed between your vehicle and a preceding vehicle is
approximately 30 km/h (20 mph) or more.
●Pre-crash braking:
• Vehicle speed is approximately 10 to 80 km/h (7 to 50 mph).
• The relative speed between your vehicle and a preceding vehicle is
approximately 10 km/h (7 mph) or more.

vehicle has not been driven for a certain amount of time
●If the shift lever is in R
●If VSC is disabled (only the pre-crash warning function will be operational)
■Cancelation of the pre-crash braking
●If either of the following occur while the pre-crash braking function is operat-
ing, it will be canceled:
• The accelerator pedal is depressed strongly.
• The steering wheel is turned sharply or abruptly.
●If the vehicle is stopped by the operation of the pre-crash braking function,
the operation of the pre-crash braking function will be canceled after the
vehicle has been stopped for approximately 2 seconds.
