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 injury such as burns.
With a hybrid vehicle, there are times when the gasoline engine automati-
cally starts to run or the cooling fans suddenly start to operate. Do not
touch or approach the rotating parts of the belt or fans. Doing so may lead
to fingers, clothes or tools getting caught, resulting in an accidental 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.

If the vehicle becomes stuck
When changing the shift position
Depress the brake pedal and ensure that the vehicle has stopped com-
pletely before changing the shift position. Failure to do so could cause the
rejection function to be activated, canceling the shift position change, or
causing the shift position to change to N automatically.
CAUTION
When attempting to free a stuck vehicle
If you choose to rock the vehicle back and forth to free it, make sure the sur-
rounding area is clear, to avoid striking other vehicles, objects or persons.
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.
This may lead to unexpected rapid acceleration of the vehicle that may
cause an accident and result 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, change the shift position to P and
stop the hybrid system.
Remove the mud, snow, or sand from around the stuck tire.
Place wood, stones or some other material to help provide
traction under the tires.
Restart the hybrid system.
Make sure to change the shift position to D or R, release
the parking brake, and then carefully apply the accelerator
to free the vehicle.STEP1

If your vehicle has to be stopped in an emergency
Only in an emergency, such as if it becomes impossible to stop the
vehicle in the normal way, stop the vehicle using the following pro-
cedure:
Steadily step on the brake pedal with both feet and firmly
depress it.
Do not pump the brake pedal repeatedly as this will increase the
effort required to slow the vehicle.
Change the shift position to N.
If the shift position can be changed to N
After slowing down, stop the vehicle in a safe place by the
road.
Stop the hybrid system.
If the shift position cannot be changed to N
Keep depressing the brake pedal with both feet to reduce
vehicle speed as much as possible.
Stop the hybrid system by
pressing and holding the
“POWER” switch for 3 consec-
utive seconds or more.
Stop the vehicle in a safe place by the road.
