Stopping the hybrid system
Set the parking brake, shift the shift position to P and press the “POWER”
switch as you normally do when stopping the hybrid system.
■ Replacing the key battery
As the above procedure is a temporary measure, it is recommended that the
electronic key battery be replaced immediately when the battery is depleted.
(P. 493)
■ Changing “POWER” switch modes
Within 10 seconds of the buzzer sounding, release the brake pedal and
press the “POWER” switch.
The hybrid system does not start and modes will be changed each time the
switch is pressed. ( P. 240)

The coolant level is satisfactory if
it is between the “FULL” and
“LOW ” lines on the reservoir.
Reservoir

Add coolant if necessary.
Water can be used in an emer-
gency if coolant is unavailable.
Start the hybrid system and turn the air conditioning system
on to check that the radiator cooling fans operate and to
check for coolant leaks from the radiator or hoses.
The fans operate when the air conditioning system is turned on
immediately after a cold start. Confirm that the fans are 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 fans may not operate in freezing temperatures.)
If the fans are not operating: Stop the hybrid system im mediately and contact your
Toyota dealer.
If the fans are operating: Have the vehicle inspected at the nearest Toyota dealer.

CAUTION
■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 indicator on the “POWER” switch and the “READY” indica-
tor are off.
● On hybrid vehicles, the gasoline engine may automatically start, or the
cooling fans may suddenly operate even if the gasoline engine stops. Do
not touch or approach rotating parts such as the fans, which may lead to
fingers 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 injury, 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 other than the Toyota genuine or similar
coolant additives

If the vehicle becomes stuck
CAUTION
■When attempting to free a stuck vehicle
If you choose to push the vehicle back and forth to free it, make sure the sur-
rounding area is clear to avoid striki ng other vehicles, objects or people. The
vehicle may also lunge forward or lu nge back suddenly as it becomes free.
Use extreme caution.
■ When changing the shift position
Be careful not to change the shift position with the accelerator pedal
depressed.
Changing the shift position to any positions other than P or N may cause the
vehicle to accelerate abruptly, causing an accident and resulting in death or
serious injury.
Carry out the following procedures if the tires spin or the vehicle
becomes stuck in mud, dirt or snow:
Set the parking brake and shift the shift position to P. Stop
the hybrid system.
Remove the mud, snow or sand from around the stuck tire.
Place wood, stones or some other material under the tires
to help provide traction.
Restart the hybrid system.
Shift the shift position to D or R, release the parking brake
and carefully apply the accelerator to free the vehicle.STEP 1
