When trouble arises
Connect the jumper cables according to the following procedure:Connect a positive jumper cable clamp to the positive (+) batte ry
terminal on your vehicle.
Connect the clamp on the other end of the positive cable to the
positive (+) battery termi nal on the second vehicle.
Connect a negative cable clamp to the negative (-) battery term i-
nal on the s econd vehicle.
Connect the clamp at the other e nd of the negative cable to a
solid, stationary, unpainted meta llic point away from the battery
and any moving parts, as shown in the illustration.
Start the engine of the second v ehicle. Increase the engine speed
slightly and maintain at that lev el for approximately 5 minutes to
recharge the batter y of your vehicle.
Open and close any of the doors of your vehicle with the engine
switch off.
Maintain the engine speed of the second vehicle and turn the
engine switch to IGNITION ON mode, then start the vehicle's
engine.

4647-2. Steps to take in an emergency
■Starting the engine when t he battery is discharged
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 running
at a low speed for an extended period, such as in heavy traffic .
■ When the battery is r emoved or discharged
● Information stored in the ECU is cleared. When the battery is d epleted, have
the vehicle inspected at your Toyota dealer.
● Some systems may require initialization. ( P. 505)
■ When removing the battery terminals
When the battery terminals are removed, the information stored in the ECU is
cleared. Before removing the battery terminals, contact 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 t ime, the battery may
discharge, and the engine may be unable to start. (The battery recharges
automatically during driving.)
■ When recharging or replacing the battery
●In some cases, it may not be possible to unlock the doors using the smart
key system when the battery is discharged. Use the wireless rem ote 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 switch mode is memorized by the vehicle. When the ba ttery is
reconnected, the system will return to the mode it was in befor e the battery
was discharged. Before disconnecting the battery, turn the engine switch off.
If you are unsure what mode the engine switch was in before the battery dis-
charged, be especially careful when reconnecting the battery.
■ When replacing the battery
●Use a battery that conforms to European regulations.
● Use a battery that the case size is same as the previous one (L N3), 20 hour
rate capacity (20HR) is equivalent (70Ah) or greater, and perfo rmance rating
(CCA) is equivalent (603A) or greater.
• If the sizes differ, the battery cannot be properly secured.
• If the 20 hour rate capacity is low, even if the time period w here the vehi-
cle is not used is a short time, the battery may discharge and the engine
may not be able to start.
● For details, consult your Toyota dealer.

When trouble arises
WARNING
■When removing the battery terminals
Always remove the negative (-) terminal first. If the positive (+) terminal con-
tacts any metal in the surrounding area when the positive (+) terminal is
removed, a spark may occur, leading to a fire in addition to el ectrical shocks
and death or serious injury.
■ Avoiding battery fires or explosions
Observe the following precautions to prevent accidentally ignit ing the flam-
mable gas that may be emitted from the 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 in tended 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 fla me near
the battery.
■ Battery precautions
The battery contains poisonous and corrosive acidic electrolyte , while
related parts contain lead and lead compounds. Observe the foll owing pre-
cautions when handling the battery:
● When working with the battery, always wear safety glasses and t ake care
not to allow any battery fluids (acid) to come into contact wit h skin, clothing
or the vehicle body.
● Do not lean over the battery.
● In the event that 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 medica l attention
can be received.
● Always wash your hands after handling the battery support, term inals, and
other battery-related parts.
● Do not allow children near the battery.
NOTICE
■When handling jumper cables
When connecting the jumper cables, ensure that they do not beco me entan-
gled in the cooling fan or engine drive belt.

4667-2. Steps to take in an emergency

tem, and then stop the engine.
If you see steam:
Carefully lift the hood after the steam subsides.
If you do not see steam:
Carefully lift the hood.
After the engine has cooled
down sufficiently, inspect the
hoses and radiator core (radia-
tor) for any leaks. Radiator
Cooling fan
If a large amount of coolant leaks,
immediately contact your Toyota
dealer.
If your vehicle overheats
The following may indicate that your vehicle is overheating.
● The needle of the engine c oolant temperature gauge (P. 90)
enters the red zone or a loss of engine power is experienced. ( For
example, the vehicle s peed does not increase.)
● “Engine Coolant Temp High Stop in a Safe Place See Owner’s
Manual” is shown on the mult i-information display.
● Steam comes out from under the hood.

When trouble arises
The coolant level is satisfactory if it is between the “F” and “L” lines
on the reservoir.
Reservoir
“F” line
“L” line
Radiator cap
Add coolant if necessary.
Water can be used in an emer-
gency if coolant is unavailable.
Start the engine and turn the ai r conditioning system on to check
that the radiator cooling fan operates and to check for coolant leaks
from the radiator or hoses.
The fan operates when the air conditioning system is turned on immedi-
ately after a cold start. Confirm that the fan is operating by checking the fan
sound and air flow. If it is difficult to check these, turn the air conditioning
system on and off repeatedly. (The fan may not operate in freez ing tem-
peratures.)
If the fan is not operating:
Stop the engine immediately and contact your Toyota dealer.
If the fan is operating:
Have the vehicle ins pected at the nearest Toyota dealer.

WARNING
■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 ho od 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 cause the hands or clot hing to be
caught, resulting in serious injury.
● Do not loosen the radiator cap and the coolant reservoir cap wh ile the
engine and radiator are hot.
High temperature steam or coolant could spray out.
NOTICE
■ When adding engine coolant
Wait until the engine has cooled down before adding engine cool ant.
When adding coolant, do so slowly. 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 sa nd or dust
etc.).
● Do not use any coolant additives.
