■ When “Check entry & start system.” is displayed on the multi-informa- 
tion display 
The system may be malfunctioning. Have the vehicle inspected by any autho- 
rized Toyota retailer or Toyota authorized repairer, or any reliable repairer 
immediately. 
■ Battery-saving function 
The battery-saving function will be activated in order to prevent the electronic 
key battery and the vehicle battery from being discharged while the vehicle is
not in operation for a long time. 
● In the following situations, the smart entry & start system may take some 
time to unlock the doors. 
• The electronic key has been left in an area of approximately 2 m (6 ft.) of 
the outside of the vehicle for 10 minutes or longer. 
• The smart entry & start system has not been used for 5 days or longer. 
● If the smart entry & start system has not been used for 14 days or longer, 
the doors cannot be unlocked at any doors except the driver’s door.  
In this case, take hold of the driver’s door handle, or use the wireless remote 
control or the mechanical key, to unlock the doors. 
■ Electronic key battery-saving function 
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.

■ 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. 356) 
● 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 pers onal digital assistants (PDAs) 
• Digital audio players
• Portable game systems 
● 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

Operation of each component

■ 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 w hen 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 or floor, or in 
the door pockets, glove box, accessory box of the instrument 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 out side, 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.)

2686-3. Do-it-yourself maintenance
YARIS_GRMN_OM_Europe_OM52J40E
■Before recharging 
When recharging, the battery produces hydrogen gas which is flammable and 
explosive. Therefore, observe  the following before recharging: 
● If recharging with the battery installed on the vehicle, be sure to disconnect 
the ground cable. 
● Make sure the power switch on the charger is off when connecting and dis- 
connecting the charger cables to the battery. 
■ After recharging/reconnecting the battery 
● Unlocking the doors using the smart entry & start system may not be possi- 
ble immediately after reconnecting the battery. If this happens, use the wire- 
less remote control or the mechanical key to lock/unlock the doors. 
● Start the engine with the engine switch in ACCESSORY mode. The engine 
may not start with the engine switch turned off. However, the engine will 
operate normally from the second attempt. 
● The engine switch mode is recorded by the vehicle. If the battery is recon- 
nected, the vehicle will return the engine switch mode to the status it was in 
before the battery was disconnected. Make sure to turn off the engine 
before disconnect the battery. Take extra care when connecting the battery
if the engine switch mode prior to discharge is unknown. 
If the engine will not start even after multiple attempts, contact any authorized 
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
WARNING
■ Chemicals in the battery
