● Do not use more than one compact spare tire simultaneously.
● Replace the compact spare tire with a standard tire as soon as possible.
● Avoid sudden acceleration, abrupt steering, sudden braking and shifting
operations that cause sudden engine braking.
■ When storing the compact spare tire
Be careful not to catch fingers or other body parts between the compact
spare tire and the body of the vehicle.
■ After using the tools and jack
Before driving, make sure all the tools and jack are securely in place in their
storage location to reduce the possibility of personal injury during a collision

Connect the jumper cables according to the following procedure.
Connect a positive jumper cable clamp to the exclusive jump start-
ing terminal on your vehicle.
Connect the clamp on the other end of the positive cable to the pos-
itive (+) battery terminal on the second vehicle.
Connect a negative cable clamp to the negative (-) battery terminal
on the second vehicle.
Connect the clamp at the other end of the negative cable to a solid,
stationary, unpainted metallic point away from the exclusive jump
starting terminal and any moving parts as shown in the illustration.
Start the engine of the second vehicle. Increase the engine speed
slightly and maintain it 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 is in the “LOCK” position (vehicles without a smart entry &
start system) or off (vehicles with a smart entry & start system).

Maintain the engine speed of the second vehicle and start the
hybrid system of your vehicle by turning the power switch to “ON”
position (vehicles without a smart entry & start system) or ON mode
(vehicles with a smart entry & start system).
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.
Close the exclusive jump starting terminal cover, and reinstall the
fuse box cover to its original position.
When installing, first hook the fuse box cover onto the two rear
tabs.
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.
■ 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 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 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 hybrid system may be unable to start. (The
12-volt battery recharges automatically while the hybrid system is operating.)

If your vehicle overheats
●The high engine coolant temperature warning light (P. 404)
comes on or flashes, or a loss of hybrid system power is experi-
enced. (For example, the vehicle speed does not increase.)
● If the hybrid system overheat warning light (P. 408) comes on.
● Steam comes out from under the hood.
■If the high engine coolant temperature warning light comes on
or flashes
Stop the vehicle in a safe place and turn off the air conditioning
system, and then stop the hybrid system.
If you see steam:
Carefully lift the hood after the steam subsides.
If you do not see steam:
Carefully lift the hood.
After the hybrid system has
cooled down sufficiently,
inspect the hoses and radia-
tor core (radiator) for any
leaks.

Stop the hybrid system and contact any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional.
If the warning light goes off:
Have the vehicle inspected at the nearest authorized Toyota dealer
or repairer, or another duly qualified and equipped professional.
WARNING
■ To prevent an accident or injury when inspecting under the hood of
your vehicle
● 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, caus-
ing serious injuries such as burns.
● Check that the “READY” indicator is off.
● On hybrid vehicles, the gasoline engine may automatically start, or the
cooling fan may suddenly operate even if the gasoline engine stops. Do
not touch or approach rotating parts such as the fan, which may lead to fin-
gers or clothing (especially a tie, a scarf or a muffler) getting caught,
resulting in serious injury.
● Do not loosen the coolant reservoir cap while the hybrid system and radia-
tor are hot.
Serious injuries, such as burns, may result from hot coolant and steam
released under pressure.

NOTICE
■When adding engine/power control unit coolant
Wait until the hybrid system has cooled down before adding engine/power
control unit coolant.
When adding coolant, do so slowly. Adding cool coolant to a hot hybrid sys-
tem too quickly can cause damage to the hybrid system.
■ 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 any coolant additives.
