ately 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 con-
ditioning system on and off repeatedly. (The fans may not operate in
freezing temperatures.)

WARNING
■ 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 hood until
the steam has subsided. The engine compartment may be very hot.
● After the hybrid system has been turned off, check that the indicator on the
power switch and the “READY” indicator are off.
When the hybrid system is operating, the gasoline engine may automati-
cally 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 radia-
tor are hot.
High temperature steam or coolant could spray out.

If the vehicle becomes stuck
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.
Carry out the following procedures if the tires spin or the vehicle
becomes stuck in mud, dirt or snow:
WARNING
■ When attempting to free a stuck vehicle
If you choose to push the vehicle back and forth to free it, make sure the
surrounding 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.
NOTICE
■To avoid damage to the hybrid transmission and other components
●Avoid spinning the wheels and depressing the accelerator pedal more
than necessary.
● If the vehicle remains stuck even after these procedures are performed,
the vehicle may require towing to be freed.
