⬛Stopping the engine
As you usually would when stopping the engine, set the shift lever to P for con-
tinuously variable transmission vehicles , and set it to N for manual transmis-
sion vehicles, then press the engine switch.
⬛Replacing the battery
The method to start the engine descri bed here is a temporary workaround. We
recommend that you replace dead batteries immediately. ( ➞P. 344)
⬛Changing the engine switch mode
In step c of “Starting the engine ”, if you press the engine switch by releasing
your foot from the clutch pedal for manual transmission vehicles and from the
brake pedal for continuously variable tr ansmission vehicles, the engine will not
start. Instead, the mode changes each time you press the switch. (➞P. 185)
⬛If the electronic key does not work properly
Check whether the electronic key is set to battery-saving mode. If the mode is
set, cancel it ( ➞P. 125)

If the vehicle battery is discharged
If the battery is discharged, you can start the engine by following the
steps below.
You can also call your Toyota deal er or a qualified repair shop.
If you have a booster cable and a second vehicle with a 12 V battery, you
can start your vehicle by following the steps below.
a Open the cover of the positive (+) battery terminal
Hold down the claw and open it.
bConnect the jumper cables accord ing to the following procedure:
a Connect a positive jumper cable clamp to the positive (+) battery ter-
minal on your vehicle.
b Connect the clamp on the other end of the positive cable to the pos-
itive (+) battery terminal on the second vehicle.
c Connect a negative cable clamp to the negative (-) battery terminal
on the second vehicle.

▶1KR-VET engine
c Start the engine of the second ve hicle. Increase the engine speed
slightly and maintain at that level for approximately 5 minutes to
recharge the battery of your vehicle.
d Maintain the engine speed of the second vehicle and turn the engine
switch to “ON”.
e Once the vehicle’s engine has started, remove the jumper cables in the
exact reverse order from which they were connected.
f Close the cover of the positive (+) battery terminal
Even if you are able to start the engine, have the vehicle inspected at your
Toyota dealer as soon as possible.
⬛Starting the engine when the battery is discharged
For this vehicle, the engine c annot be started by push-starting.
⬛If the vehicle battery is discharged
The data stored in the comp uter will be erased. If your vehicle’s battery dis-
charges, have the vehicle insp ected at your Toyota dealer.
⬛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 auto-
matically during driving)

⬛When your battery is discharged/removed (vehicles with key-free system)
⚫You may not be able to unlock the vehicle doors using the key-free system
immediately after battery discharge. In such cases, lock and unlock the
doors using the wireless remote control or emergency key.
⚫The vehicle engine may not start on the first try after battery discharge. This
is to be expected, and the engine will start properly on the second try
onward.
⚫The vehicle consistently keeps track of its engine switch mode. Even after a
discharged battery is removed, the en gine mode returns to the state before
removing the battery. Please remove the battery after turning the engine
switch “OFF”.
If you are not sure of the engine swit ch mode prior to battery discharge, be
especially careful when connecting the battery.
WARNING
⬛Avoiding battery fires or explosions
Observe the following precautions to prev ent the fire and sparks to be gener-
ated as these may ignite the flammab le gas emitted from the battery of the
second vehicle and cause an explosion:
⚫Make sure each jumper cable is connec ted 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 jump er cable connected to the “+” terminal
to come into contact with any other pa rts 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 li ghters or allow open flame near the
battery
⚫Do not use or charge the battery when the battery level is lower than the
LOWER LEVEL displayed on the side of the battery
⬛Battery precautions
The battery contains poisonous and corr osive acid electrolyte, while related
parts contain lead and lead compounds. Observe the following precautions
when handling the battery:
⚫When working with the battery, always wear safety glasses and take care not
to allow any battery fluids (acid) to co me into contact with skin, clothing or
the vehicle body
⚫Keep your face and head away from the battery as much as possible

⚫In the event that battery fluid comes into contact with the skin or eyes,
immediately wash the affected area with plenty of water and seek medical
attention
Place a wet sponge or cloth over the affected area until medical attention
can be received
⚫If you accidentally swallow electrolyte
Drink a large quantity of water or milk. Get emergency medical attention
immediately.
⚫Always wash your hands after handling the battery and other peripheral

Tighten them securely. If the nuts loosen while driving, it may cause a short cir-
cuit and result in a fire.
⬛To prevent damage to the vehicle
Do not start the vehicle by pushing or pulling it.
The catalytic converter may overheat and cause a fire.
NOTICE
⬛To prevent battery discharge
⚫Turn off the lights and air conditioning system when the engine is not run-
ning.
⚫If you stop for a long time due to a traffic jam or other situations, turn off
unnecessary electrical components.

If your vehicle overheats
The following may indicate that your vehicle is overheating:
⚫High coolant temperat ure warning light (➞P. 379) is flashing or lit in red
⚫Vehicles with TFT color multi-information display: “Engine Coolant
Temp High” warning message ( ➞P. 387) is displayed
⚫A loss of engine power is experienced (the vehicle cannot reach
higher speeds, etc.)
⚫Steam comes out from th e engine compartment
Measures to take
⬛The high coolant temperature warn ing light is flashing or lit
a Stop the vehicle in a safe place an d turn OFF the air conditioning sys-
tem, and then stop the engine
b If you see steam:
After making sure that the steam has stopped, carefully lift the hood
If you do not see steam:
Carefully lift the hood
c After the engine has cooled
down sufficiently, inspect the
hoses and radiator core (radiat-
ing part) for any leaks

b Radiator
If a large amount of coolant has leaked,
immediately contact your Toyota
dealer.
d Check that the amount of coolant

eAdd coolant if necessary
Water can be used in an emergency if
coolant is unavailable.
fStart the engine and turn the air co nditioning system on to check that
the radiator cooling fan operates and to check again for coolant leaks
from the radiator core or hoses
The fan operates when the air conditioning system is turned on immediately after a
cold start. Confirm that the fan is operat ing by checking the fan sound and air flow.
If it is difficult to check them, turn the air conditioning system ON and OFF repeat-
edly.
(The fan may not operate in freezing temperatures)
g If the fan is not operating:
Stop the engine immediately and contact your Toyota dealer
If the fan is operating:
Have the vehicle inspected at the nearest Toyota dealer
WARNING
⬛Before taking measures
Do not remove the radiator cap if the coolant is hot. The radiator cap is under
the pressure of the coolant. Therefore, steam or hot water may spurt out of it,
causing serious injury such as burns.
⬛To prevent an accident or injury 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 (especially a tie, a scarf or a muffler) away from the
fan and belts. Failure to do so may caus e the hands or clothing to be caught,
resulting in serious injury.
⚫Do not loosen the radiator cap an d the coolant reservoir cap while the
engine and radiator are hot. High te mperature steam or coolant could spray
out.
