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 discon-
nect the ground cable.
Make sure the power switch on the charger is off when connecting and
disconnecting the charger cables to the battery.
After recharging/reconnecting the battery (vehicles with a smart entry
& start system)
Unlocking the doors using the smart entry & start system may not be
possible immediately after reconnecting the battery. If this happens, use
the wireless remote control or the mechanical key to lock/unlock the
doors.
Start the engine with the “ENGINE START STOP” switch in ACCES-
SORY mode. The engine may not start with the “ENGINE START STOP”
switch turned off. However, the engine will operate normally from the sec-
ond attempt.
The “ENGINE START STOP” switch mode is recorded by the vehicle. If
the battery is reconnected, the vehicle will return the “ENGINE START
STOP” switch mode to the status it was in before the battery was discon-
nected. Make sure to turn off the engine before disconnect the battery.
Take extra care when connecting the battery if the “ENGINE START
STOP” switch mode prior to discharge is unknown.
If the engine will not start even after multiple attempts, contact any autho-
rized Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional.

5-2. Steps to take in an emergency
When trouble arises
YARIS_F (including HV)_WE_52C79E
If the electronic key does not operate properly
Unlocking and locking the doors
Use the mechanical key (P. 66)
in order to perform the following
operations:
Unlocks all the doors
Locks all the doors
Starting the hybrid system (hybrid vehicle)
Vehicles with a hybrid transmission
Ensure that the shift lever is in P and firmly depress the brake
pedal.
: If equipped
If communication between the electronic key and vehicle is inter-
rupted (P. 78) 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 (except hybrid vehicle) or hybrid system
(hybrid vehicle) can be started by following the procedure below.

623 5-2. Steps to take in an emergency
When trouble arises
YARIS_F (including HV)_WE_52C79E
Stopping the engine (except hybrid vehicle)
Vehicles with a Multidrive: Shift the shift lever to P and press the “ENGINE
START STOP” switch as you normally do when stopping the engine.
Except vehicles with a Multidrive: Shift the shift lever to N and press the
“ENGINE START STOP” switch as you normally do when stopping the
engine.
Stopping the hybrid system (hybrid vehicle)
Shift the shift lever to P and press the “POWER” switch as you normally do
when stopping the hybrid system.
Replacing the key battery
As the above procedure is a temporary measure, it is recommended that the
electronic key battery be replaced immediately when the battery is depleted.
(P. 505)
If the doors cannot be locked or unlocked by the smart entry & start
system
Lock and unlock the doors by the mechanical key or wireless remote control.
When the electronic key does not work properly
Make sure that the smart entry & start system has not been deactivated in
the customization setting. If it is off, turn the function on.
(Customizable features P. 682)

628 5-2. Steps to take in an emergency
YARIS_F (including HV)_WE_52C79E
Starting the engine when the battery is discharged (vehicles with a
Multidrive)
The engine cannot be started by push-starting.
To prevent battery discharge
Turn off the headlights and the audio system while the engine is off.
Turn off any unnecessary electrical components when the vehicle is run-
ning at a low speed for an extended period, such as in heavy traffic.
Charging the battery
The electricity stored in the battery will discharge gradually even when the
vehicle is not in use, due to natural discharge and the draining effects of cer-
tain electrical appliances. If the vehicle is left for a long time, the battery may
discharge, and the engine may be unable to start. (The battery recharges
automatically during driving.)
Precautions when the battery is discharged (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.
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.
The “ENGINE START STOP” switch mode is memorized by the vehicle.
When the battery is reconnected, the system will return to the mode it
was in before the battery was discharged. Before disconnecting the bat-
tery, turn the “ENGINE START STOP” switch off.
If you are unsure what mode the “ENGINE START STOP” switch was in
before the battery discharged, be especially careful when reconnecting
the battery.
