■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 of f, check that the indicator on the power
switch and the “READY” indicator are off.
When the hybrid system is operating, 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 fa n, which may lead to fingers or clothing
(especially a tie, a scarf or a muffler) ge tting caught, resulting in serious injury.
●Do not loosen the radiator cap or the co olant reservoir cap while the hybrid system
and radiator are hot. High temperature steam or coolant could spray out.
NOTICE
■When adding engine/power control unit coolant
Add coolant slowly after the hybrid system has cooled down sufficiently. Adding cool
coolant to a hot hybrid system 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.

Remove the mud, snow or sand from around the front wheels.
Place wood, stones or some other material under the front wheels to help pro-
vide traction.
Restart the hybrid system.
Shift the shift lever to D or R and release the parking brake. Then, while exer-
cising caution, depress the accelerator pedal.

Press to turn off TRAC. ( P. 2 7 3 )
WA R N I N G
■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 vehicl es, objects or people. The vehicle may also
lunge forward or lunge back suddenly as it becomes free. Use extreme caution.
■When shifting the shift lever
Be careful not to shift the shift lever with the accelerator pedal depressed.
This may lead to unexpected rapid accelerati on of the vehicle that may cause an acci-
dent resulting in death or serious injury.
