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.

If the vehicle batter y is discharged (except hybrid vehicle)
The following procedures may be used to start the engine if the vehi-
cle's battery is discharged.
You can also call any authorized Toyota dealer or repairer, or another
duly qualified and equipped professional.
If you have a set of jumper (or booster) cables and a second vehi-
cle with a 12-volt battery, you can jump start your vehicle by follow-
ing the steps below.
Open the hood. (P. 462)
Connect the jumper cables according to the following pro-
cedure:
1KR-FE engine
Connect a positive jumper cable clamp to the positive (+) battery
terminal on your vehicle.
Connect the clamp on the other end of the positive cable to the
positive (+) battery terminal on the second vehicle.
Connect a negative cable clamp to the negative (-) battery termi-
nal on the second vehicle.
Connect the clamp at the other end of the negative cable to a
solid, stationary, unpainted metallic point away from the battery
and any moving parts as shown in the illustration.

If the vehicle’s 12-volt batter y is discharged (hybrid vehicle)
The following procedures may be used to start the hybrid system if
the vehicle’s 12-volt battery is discharged.
You can also call any authorized Toyota dealer or repairer, or another
duly qualified and equipped professional.
If you have a set of jumper (or booster) cables and a second vehi-
cle with a 12-volt battery, you can jump start your vehicle by follow-
ing the steps below.
Remove the 12-volt battery cover. (P. 487)
Connect the jumper cables according to the following procedure:
Connect a positive jumper cable clamp to the positive (+) battery
terminal on your vehicle.
Connect the clamp on the other end of the positive cable to the
positive (+) battery terminal on the second vehicle.
Connect a negative cable clamp to the negative (-) battery termi-
nal on the second vehicle.
Connect the clamp at the other end of the negative cable to the
negative (-) battery terminal on your vehicle as shown in the
illustration.
Do not hold the negative cable together with negative (-) battery termi-
nal by the jumper cable clamp when you connect to the negative (-)
battery terminal.
Start the engine of the second vehicle. Increase the engine
speed slightly and maintain that level for approximately 5
minutes to recharge the 12-volt battery of your vehicle.

Starting the hybrid system when the 12-volt battery is discharged
The hybrid system cannot be started by push-starting.
To prevent 12-volt battery discharge
Turn off the headlights and the audio system while the hybrid system 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.
Precautions when the 12-volt battery is discharged
In some cases, it may not be possible to unlock the doors using the smart
entry & start system immediately after the 12-volt battery has been dis-
connected and reconnected. Use the wireless remote control or the
mechanical key to lock or unlock the doors.
Open and close any of the doors of your vehicle with the
engine switch (vehicles without an electronic key) or
“POWER” switch (vehicles with an electronic key) off.
Maintain the engine speed of the second vehicle and start
the hybrid system of your vehicle by turning the engine
switch (vehicles without an electronic key) to “ON” position
or “POWER” switch (vehicles with an electronic key) to ON
mode.
Make sure the “READY” indicator comes on. If the indicator
does not come on, contact any authorized Toyota dealer or
repairer, or another duly qualified and equipped profes-
sional.
Once the hybrid system has started, remove the jumper
cables in the exact reverse order from which they were con-
nected.
Once the hybrid system starts, have the vehicle inspected at any
authorized Toyota dealer or repairer, or another duly qualified and
equipped professional as soon as possible.

When trouble arises
YARIS_F (including HV)_WE_52C79E
The hybrid system may not start on the first attempt after the 12-volt bat-
tery has recharged but will start normally after the second attempt. This is
not a malfunction.
Vehicles with an electronic key: The “POWER” switch mode is memo-
rized by the vehicle. When the 12-volt battery is reconnected, the system
will return to the mode it was in before the 12-volt battery was dis-
charged. Before disconnecting the 12-volt battery, turn the “POWER”
switch off.
If the “POWER” switch was in ACCESSORY or ON mode before the 12-
volt battery was discharged, the audio system and/or air conditioning
system may operate when the 12-volt battery is reconnected.
Charging the 12-volt battery
The electricity stored in the 12-volt battery will discharge gradually even
when the vehicle is not in use, due to natural discharge and the draining
effects of certain electrical appliances. If the vehicle is left for a long time, the
12-volt battery may discharge, and the hybrid system may be unable to start.
(The 12-volt battery recharges automatically while the hybrid system is oper-
ating.)
CAUTION
Avoiding 12-volt battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flam-
mable gas that may be emitted from the 12-volt battery:
Make sure each jumper cable is connected to the correct terminal and that
it is not unintentionally in contact with anything other than the intended ter-
minal.
Do not allow the other end of the jumper cable connected to the “+” termi-
nal to come into contact with any other parts or metal surfaces in the area,
such as brackets or unpainted metal.
Do not allow the + and - clamps of the jumper cables to come into contact
with each other.
Do not smoke, use matches, cigarette lighters or allow open flame near
the 12-volt battery.
