Security feature
If a door is not opened within approximately 30 seconds after the vehicle is
unlocked, the security feature automatically locks the vehicle again.
To operate the system properly
Make sure to carry the electronic key when operating the 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 system may not operate properly.
(The alarm may go off accidentally, or the door lock prevention function may
not operate.)
If the smart entry & start system does not operate properly
Locking and unlocking the doors: Use the mechanical key. (P. 619)
Starting the engine (except hybrid vehicle) or the hybrid system (hybrid
vehicle): P. 619
Electronic key battery depletion
The standard battery life is 1 to 2 years.
If the battery becomes low, an alarm will sound in the cabin when the
engine (except hybrid vehicle) or the hybrid system (hybrid vehicle)
stops. (P. 575)
As the electronic key always receives radio waves, the battery will
become depleted even if the electronic key is not used. The following
symptoms indicate that the electronic key battery may be depleted.
Replace the battery when necessary. (P. 505)
• The smart entry & start system or the wireless remote control does not
operate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.
To avoid serious deterioration, do not leave the electronic key within 1 m
(3 ft.) of the following electrical appliances that produce a magnetic field:
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Recharging cellular phones or cordless phones
• Glass top ranges

areas), the system may not operate properly.
For example, the electronic key is on the instrument panel, luggage
cover, floor or in the glove box when the hybrid system is started or
“POWER” switch modes are changed.
Even if the electronic key is not inside the vehicle, it may be possible to
start the hybrid system if the electronic key is near the window.
To operate the system properly
Make sure to carry the electronic key when operating the system.
Depending on the position and holding condition of the electronic key, the
key may not be detected correctly and the system may not operate properly.
(The alarm may go off accidentally, or the door lock prevention may not func-
tion.)

CAUTION
Caution regarding interference with electronic devices
People with implanted pacemakers or cardiac defibrillators should keep
away from the push-button start system antennas. (P. 95)
The radio waves may affect the operation of such devices. If necessary,
the push-button start system can be disabled. Ask any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional for
details, such as the frequency of radio waves and timing of emitting the
radio waves. Then, consult your doctor to see if you should disable the
push-button start system.
Users of any electrical medical device other than implanted pacemakers
and implanted cardiac defibrillators should consult the manufacturer of the
device for information about its operation under the influence of radio
waves. Radio waves could have unexpected effects on the operation of
such medical devices.
Ask any authorized Toyota dealer or repairer, or another duly qualified and
equipped professional for details on disabling the push-button start system.

When driving
YARIS_F (including HV)_WE_52C79E
Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability
of the correct fuel. (P. 660)
For efficient use (Hybrid vehicle)
Shift the shift lever to D when driving.
In the N position, the gasoline engine operates but electricity cannot be
generated. The hybrid battery (traction battery) will discharge, requiring
unnecessary engine power to recharge.
Drive your vehicle smoothly.
Avoid abrupt acceleration and deceleration. Gradual acceleration and
deceleration will make more effective use of the electric motor (traction
motor) without having to use gasoline engine power.
Avoid repeated acceleration.
Repeated acceleration consumes hybrid battery (traction battery) power,
resulting in poor acceleration. Battery power can be restored by driving
with the accelerator pedal slightly released.
Shift the shift lever to P when parking.
In the N position, the hybrid battery (traction battery) does not recharge.
Leaving the shift lever in the N position for an extended period of time
may discharge the hybrid battery. The vehicle cannot run if the hybrid
battery is discharged.

CAUTION
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” position to stop the engine. An accident may
result if the engine is stopped while driving. (P. 650)
NOTICE
To prevent battery discharge
Do not leave the engine switch in the “ACC” or “ON” position for long periods
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 dealer or repairer, or another duly
qualified and equipped professional immediately.
