Stopping the hybrid system
Set the parking brake, shift the shift position to P and press the “POWER”

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” indi-
cator are 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
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 radi-
ator 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 commercially available 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 striking other vehicles, objects or people. The
vehicle may also lunge forward or lunge 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 parkingSTEP1
