■ 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 immobilizer system from operating properly.
(Ways of coping: P. 747)
● 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 devices
• Another 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
● When parking at a meter

C-HR_OM_Europe_OM10528E
● 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 sensor while wearing gloves may delay or prevent
lock operation. Remove the gloves and touch the lock sensor again.
● 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. 173)
● If the electronic key is inside the vehicle and a door handle becomes wet
during a car wash, a message may be shown on the multi-information dis-
play and a buzzer will sound outside the vehicle. To turn off the alarm, lock
all the doors.
● The lock sensor may not work properly if it comes into contact with ice,
snow, mud, etc. Clean the lock sensor and attempt to operate it again.
● A sudden approach to the effective range or door handle may prevent the
doors from being unlocked. In this case, return the door handle to the origi-
nal position and check that the doors unlock before pulling the door handle
again.
● If there is another electronic key in the detection area, it may take slightly
longer to unlock the doors after the door handle is gripped.
● Fingernails may scrape against the door during operation of the door han-
dle. Be careful not to injure fingernails or damage the surface of the door.

Operation of each component
C-HR_OM_Europe_OM10528E
■ When the vehicle is not driven for extended periods
● To prevent theft of the vehicle, do not leave the electronic key within 2 m
(6 ft.) of the vehicle.
● The smart entry & start system can be deactivated in advance. (P. 776)
■ 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 may not operate.)
■ If the smart entry & start system does not operate properly
● Locking and unlocking the doors: Use the mechanical key. (P. 747)
● Starting the engine: P. 748
■ Customization
Settings (e. g. smart entry & start system) can be changed.
(Customizable features: P. 776)
■ If the smart entry & start system has been deactivated in a customized
setting
● Locking and unlocking the doors:
Use the wireless remote control or mechanical key. ( P. 156, 747)
● Starting the engine and changing engine switch modes: P. 748
● Stopping the engine: P. 237

Maintenance and care
C-HR_OM_Europe_OM10528E
■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 (vehicles with a smart entry &
start system)
● The engine may not start. Follow the procedure below to initialize the sys-
tem.
Shift the shift lever to P (Multi drive) or N (manual transmission).
Open and close any of the doors.
Restart the engine.
● 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 disconnecting the battery. Take extra care when connecting the bat-
tery if the engine switch mode prior to discharge is unknown.
If the system will not start even after multiple attempts at all methods above,
contact any authorized Toyota retailer or Toyota authorized repairer, or any
reliable repairer.

● Batteries can be purchased at any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer, local electrical appliance shops
or camera stores.
● Replace only with the same or equivalent type recommended by the manu-
facturer.
● Dispose of used batteries according to local laws.
■ If the key battery is depleted
The following symptoms may occur:

If the electronic key does not operate properly
(vehicles with a smart entry & start system)
Use the mechanical key ( P. 146) in order to perform the following
operations:
Locks all the doors
Closes the windows (turn and
hold)*
Unlocks all the doors
Opens the windows (turn and
hold)*
*: These settings must be custom-

If communication between the electronic key and vehicle is
interrupted ( P. 174) or the electronic key cannot be used
because the battery is depleted, the smart entry & start system
and wireless remote control cannot be used. In such cases, the
doors can be opened and the engine can be started by following
the procedure below.

■ When recharging or replacing the battery
● Vehicles with a smart entry & start system: In some cases, it may not be
possible to unlock the doors using the smart entry & start system when the
battery is discharged. Use the wireless remote control or the mechanical
key to lock or unlock the doors.
● Vehicles with a smart entry & start system: The engine may not start on the
first attempt after the battery has recharged but will start normally after the
second attempt. This is not a malfunction.
● Vehicles with a smart entry & start system: The engine switch mode is mem-
orized by the vehicle. When the battery is reconnected, the system will
return to the mode it was in before the battery was discharged. Before dis-
connecting the battery, turn the engine switch off.
If you are unsure what mode the engine switch was in before the battery dis-
charged, be especially careful when reconnecting the battery.
● Vehicles with a Stop & Start system: For a while after the battery terminals
have been disconnected or reconnected, for a while after the battery has
been replaced, the Stop & Start system may not automatically stop the
engine for approximately 5 to 60 minutes.
■ When exchanging the battery (vehicles with a Stop & Start system)
Use a battery specified for use with the Stop & Start system and equivalent to
a genuine battery. If an unsupported battery is used, Stop & Start system
functions may be restricted to protect the battery.
Also, battery performance may decrease and the engine may not be able to
restart. Contact any authorized Toyota retailer or Toyota authorized repairer,
or any reliable repairer for details.
