YARIS_F (including HV)_WE_52D27E
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. 501)

625 5-2. Steps to take in an emergency
When trouble arises
YARIS_F (including HV)_WE_52D27E
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.

When trouble arises

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.
