When trouble arises
cannot be started, contact your Toy-
ota dealer.
■Stopping the EV system
Shift the shift position to P, set the
parking brake and press the power
switch as you no rmally do when
stopping the EV system.
■Replacing the key battery
As the above proc edure is a tempo-
rary measure, it is recommended
that the electronic key battery be
replaced immediate ly when the bat-
tery is depleted. ( P.497)
■Alarm
If a door is unlocked using the
mechanical key when the alarm sys-
tem is set, the alarm may be trig-
gered. ( P. 6 9 )
■Changing power switch modes
Release the brake pedal and press
the power switch in step 3 above.
The EV system does not start and
modes will be cha nged each time
the switch is pressed. ( P.234)
If you have a set of jumper (or
booster) cables and a second
vehicle with a 12-volt battery,
you can jump start your vehicle
by following the steps below.
1Confirm that the electronic
key is being carried.
When connecting the jumper (or
booster) cables, depending on the
situation, the alarm may activate
and the doors locked. ( P. 7 0 )
2 Open the hood ( P.462).
3 Open the positive (+) battery
terminal cover.
While pressing on the claw, open
the cover as shown in the illustra-
If the 12-volt batter y is
discharged
The following procedures
may be used to start the EV
system if the vehicle’s 12-
volt battery is discharged.
You can also call your Toy-
ota dealer or a qualified
repair shop.

5 Start the engine of the sec-
ond vehicle. Increase the
engine speed slightly and
maintain at that level for approximately 5 minutes to
recharge the 12-volt battery
of your vehicle.

When trouble arises
6 Open and close any of the
doors of your vehicle with the
power switch OFF.
7 Maintain the engine speed of
the second vehicle and start
the EV system of your vehi-
cle by turning the power
switch to ON.
8 Make sure the “READY” indi-
cator comes on. If the indica-
tor light does not come on,
contact your Toyota dealer.
9 Once the EV system has
started, remove the jumper
cables in the exact reverse
order from which they were
connected.
10 Close the positive (+) battery
terminal cover.
Once the EV system starts,
have the vehicle inspected at
your Toyota dealer as soon as
possible.
■Starting the EV system when
the 12-volt battery is dis-
charged
The EV system cannot be started by
push-starting.
■To prevent 12-volt battery dis-
charge
●Turn off the headlights, the air
conditioning system, the audio
system, etc. while the EV system
is off.
●Turn off any unnecessary electri-
cal components when the vehicle
is running at a low speed for an
extended period, such as in heavy
traffic.
■Charging the 12-volt battery
The electricity stored in the 12-volt
battery will discha rge gradually even
when the vehicle i s not in use, due
to natural dischar ge and the drain-
ing effects of certain electrical appli-
ances. If the vehicle is left for a long
time, the 12-volt battery may dis-
charge, and the EV system may be
unable to start. (The 12-volt battery
recharges automatically while the
EV system is operating.)
■When the 12-volt battery is
removed or discharged
●Information stored in the ECU is
cleared. When the 12-volt battery
is depleted, have the vehicle
inspected at your Toyota dealer.
●In some cases, it may not be pos-
sible to unlock the doors using the
smart key system when the 12-
volt battery is discharged. Use the
wireless remote c ontrol or the
mechanical key to lock or unlock
the doors.
●The EV system may not start on
the first attempt a fter the 12-volt
battery has recharged but will start
normally after the second attempt.
This is not a malfunction.
●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 discharged. Before discon-
necting the 12-volt battery, turn
the power switch off.
If you are unsure what mode the
power switch was in before the
12-volt battery discharged, be
especially careful when recon-
necting the 12-volt battery.
●If the 12-volt battery discharges, it
may not be possible to shift the
shift position to o ther positions. In
this case, the vehicle cannot be
towed without lifting both front
wheels because the front wheels
will be locked.
●The power back door (if equipped)

5448-2. Steps to take in an emergency
Owners Manual_USA_M42C01_enmust be initialized. (
P.181)
■When replacing the 12-volt bat-
tery
●Use a 12-volt battery that con-
forms to European regulations.
●Use a 12-volt battery that the case
size is same as the previous one
(LN1), 20 hour rate capacity
(20HR) is equiva lent (45Ah) or
greater, and performance rating
(CCA) is equivalent (286A) or
greater.
• If the sizes differ, the 12-volt bat- tery cannot be properly secured.
• If an improper 12- volt battery is
used, battery performance may
decrease and the EV system may
not be able to restart.
• If the 20 hour rate capacity is low,
even if the time period where the
vehicle is not used is a short time,
the 12-volt battery may discharge
and EV system may not be able to
start.
For details, consult your Toyota
dealer.
WARNING
■When removing the 12-volt
battery terminals
Always remove the negative (-)
terminal first. If the positive (+) ter-
minal contacts any metal in the
surrounding area when the posi-
tive (+) terminal is removed, a
spark may occur, l eading to a fire
in addition to electrical shocks
and death or serious injury.
■Avoiding 12-volt battery fires
or explosions
Observe the following precautions
to prevent accidentally igniting the
flammable gas that may be emit-
ted from the 12-volt battery:
●Make sure each jumper cable is
connected to the correct termi-
nal and that it is not unintention-
ally in contact with any other
than the intended terminal.
●Do not allow the other end of
the jumper cable connected to
the “+” terminal 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 lighter s or allow open
flame near the 1 2-volt battery.
■12-volt battery precautions
The 12-volt battery contains poi-
sonous and corrosive acidic elec-
trolyte, while related parts contain
lead and lead compounds.
Observe the following precautions
when handling the 12-volt battery:
●When working with the 12-volt
battery, always wear safety
glasses and take care not to
allow any battery fluids (acid) to
come into contact with skin,
clothing or the vehicle body.
●Do not lean over the 12-volt bat-
tery.
●In the event that battery fluid
(acid) comes into contact with
the skin or eyes, immediately
wash the affected area with
water and seek medical atten-
tion.
Place a wet sponge or cloth
over the affected area until
medical attention can be
received.
●Always wash your hands after
handling the 12-volt battery and
other battery-related parts.
●Do not allow children near the
12-volt battery.

the hold down cl amp, the bat-
tery fluid (acid) may leak.
●For information regarding bat-
tery replacement, contact your
Toyota dealer.

occur when water or any other
type of coolant is used, so never
use any other fluid. When there is
no “Toyota Genuine Traction Bat-
tery Coolant”, immediately contact
your Toyota dealer.
