When trouble arises
Start the engine of the second vehicle. Increase the engine speed
slightly and maintain at that level for approximately 5 minutes to
recharge the 12-volt battery of your vehicle.
Open and close any of the doors of your vehicle with the engine
switch off.
Vehicles without a smart entry & start system:
Maintain the engine speed of the second vehicle and turn the
engine switch to the “ON” position, then start the vehicle's engine.
Vehicles with a smart entry & start system:
Maintain the engine speed of the second vehicle and turn the
engine switch to IGNITION ON mode, then start the vehicle's
engine.
Once the vehicle’s engine has started, remove the jumper cables in
the exact reverse order from which they were connected.
Once the engine starts, have the vehicle inspected at any authorized
Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional as soon as possible.
Starting the engine when the 12-volt battery is discharged
The engine cannot be started by push-starting.
To prevent 12-volt 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 running
at a low speed for an extended period, such as in heavy traffic.
When the 12-volt battery is removed or discharged (vehicles with an
alarm)
Make sure that the key is not inside the vehicle when recharging or replacing
the battery. The key may be locked in the vehicle if the alarm is activated.
(P. 105)
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 engine may be unable to start. (The 12-volt
battery recharges automatically during driving.)

6787-2. Steps to take in an emergency
UK_AURIS/AURIS_HV_EE (OM12E33E)When recharging or replacing the 12-volt battery
Vehicles with an alarm: Make sure the key is not inside the vehicle when
recharging or replacing the 12-volt battery to prevent the doors from being
locked with the key left inside the vehicle when the alarm operates.
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 12-volt battery has
recharged but will start normally after the second attempt. This is not a mal-
function.
The engine switch mode is memorized by the vehicle. When the 12-volt bat-
tery is reconnected, the system will return to the mode it was in before the
12-volt battery was discharged. Before disconnecting the 12-volt battery,
turn the engine switch off.
If you are unsure what mode the engine switch was in before the 12-volt
battery discharged, be especially careful when reconnecting the 12-volt bat-
tery.
CAUTION
Avoiding 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 any other than the intended terminal.
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.

When trouble arises
CAUTION
12-volt battery precautions
The 12-volt battery contains poisonous and corrosive acidic electrolyte,
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 12-volt battery fluids (acid) to come into contact
with skin, clothing or the vehicle body.
Do not lean over the 12-volt battery.
In the event that 12-volt battery fluid comes into contact with the skin or
eyes, immediately wash the affected area with water and seek medical
attention.
Place a wet sponge or cloth over the affected area until medical attention
can be received.
Always wash your hands after handling the battery support, terminals, and
other 12-volt battery-related parts.
Do not allow children near the 12-volt battery.
NOTICE
When handling jumper cables
When connecting the jumper cables, ensure that they do not become entan-
gled in the cooling fans or engine drive belt.

When trouble arises
Connect the jumper cables according to the following procedure:
Positive (+) battery terminal on your vehicle
Positive (+) battery terminal on the second vehicle
Negative (-) battery terminal on the second vehicle
Negative (-) battery terminal on your vehicle
Start the engine of the second vehicle. Increase the engine speed
slightly and maintain at that level for approximately 5 minutes to
recharge the 12-volt battery of your vehicle.
Open and close any of the doors of your vehicle with the power
switch off.
Maintain the engine speed of the second vehicle and start the
hybrid system of your vehicle by turning the power switch 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 professional.
Once the hybrid system has started, remove the jumper cables in
the exact reverse order from which they were connected.
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.3

When trouble arises
Stop the vehicle in a safe place and turn off the air conditioning sys-
tem.
Check to see if steam is coming out from under the hood.
If you see steam:
Stop the engine. Carefully lift the hood after the steam subsides and
then restart the engine.
If you do not see steam:
Leave the engine running and carefully lift the hood.
Check to see if the cooling fan is operating.
If the fan is operating:
Wait until the temperature of the engine (shown on the instrument
panel) begins to fall and then stop the engine.
If the fan is not operating:
Stop the engine immediately and call any authorized Toyota dealer
or repairer, or another duly qualified and equipped professional.
After the engine has cooled
down sufficiently, check the
engine coolant level and
inspect the radiator core (radia-
tor) for any leaks.
Add engine coolant if neces-
sary.
Water can be used in an emer-
gency if engine coolant is unavail-
able. (P. 709)

Have the vehicle inspected at the nearest any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional
as soon as possible.
Overheating
If you observe the following, your vehicle may be overheating:
Vehicles without a multi-information display: The high engine coolant tem-
perature warning light comes on or a loss of power is experienced.
Vehicles with a multi-information display: The high engine coolant tempera-
ture gauge enters the red zone or a loss of power is experienced.
Steam comes out from under the hood.
CAUTION
When inspecting under the hood of your vehicle
Observe the following precautions.
Failure to do so may result in serious injury such as burns.
If steam is seen coming from under the hood, do not open the hood until
the steam has subsided. The engine compartment may be very hot.
Keep hands and clothing away from the fans, etc. while the engine is oper-
ating.
Do not loosen the coolant reservoir cap while the engine and radiator are
hot.
NOTICE
When adding engine coolant
Add coolant slowly after the engine has cooled down sufficiently. Adding
cool coolant to a hot engine too quickly can cause damage to the engine.
To prevent damage to the cooling system
Observe the following precautions:
Avoid contaminating the coolant with foreign matter (such as sand or dust
etc.).
Do not use commercially available coolant additives.
