■Running out of fuel
When the vehicle has run out of fuel and the hybrid system cannot be started,
refuel the vehicle with at least enough gasoline to make the low fuel level warn-ing light ( P.442) go off. If there is only
a small amount of fuel, the hybrid sys- tem may not be able to start. (The stan-dard amount of fuel is about 6.3 L [1.7
gal., 1.4 Imp. gal.] when the vehicle is on a level surface. This value may vary when the vehicle is on a slope. Add
extra fuel when the vehicle is inclined.)
■Electromagnetic waves
●High voltage parts and cables on
hybrid vehicles incorporate electro- magnetic shielding, and therefore emit approximately the same amount of
electromagnetic waves as conven- tional gasoline powered vehicles or home electronic appliances.
●Your vehicle may cause sound inter-ference in some third party-produced
radio parts.
■Hybrid battery (traction battery)
The hybrid battery (traction battery) has
a limited service life. The lifespan of the hybrid battery (traction battery) can change in accordance with driving style
and driving conditions.
■Starting the hybrid system in an extremely cold environment
When the hybrid battery (traction bat-
tery) is extremely cold (below approxi- mately -30°C [-22°F]) under the influence of the outside temperature, it
may not be possible to start the hybrid system. In this case, try to start the hybrid system again after the tempera-
ture of the hybrid battery increases due to the outside temperature increase etc.
■Declaration of conformity
This model conforms to hydrogen emis-
sions according to regulation ECE100
(Battery electric vehicle safety).
WARNING
■High voltage precautions
This vehicle has high voltage DC and AC systems as well as a 12-volt sys-tem. DC and AC high voltage is very
dangerous and can cause severe burns and electric shock that may result in death or serious injury.
●Never touch, disassemble, remove or replace the high voltage parts,
cables or their connectors.
●The hybrid system will become hot
after starting as the system uses high voltage. Be careful of both the high voltage and the high tempera-
ture, and always obey the warning labels attached to the vehicle.
●Never try to open the service plug access hole located under the left side of the rear seat. The service
plug is used only when the vehicle is serviced and is subject to high voltage.
■Road accident cautions
Observe the following precautions to
reduce the risk of death or serious injury:
●Pull your vehicle off the road, apply the parking brake, shift the shift lever to P, and turn the hybrid sys-
tem off.

reduce the risk of accidents. Failure to do so may result in a loss of vehicle control and cause death or
serious injury.
●Use tires of the size specified.
●Maintain the recommended level of air pressure.
●Do not drive at speeds in excess of the speed limit or the speed limit specified for the snow tires being
used.
●Use snow tires on all, not just some
wheels.
■Driving with tire chains
Observe the following precautions to reduce the risk of accidents.Failure to do so may result in the vehi-
cle being unable to be driven safely, and may cause death or serious injury.
●Do not drive in excess of the speed limit specified for the tire chains
being used, or 50 km/h (30 mph), whichever is lower.
●Avoid driving on bumpy road sur-faces or over potholes.
●Avoid sudden acceleration, abrupt steering, sudden braking and shift-ing operations that cause sudden
engine braking.
●Slow down sufficiently before enter-
ing a curve to ensure that vehicle control is maintained.
●Do not use LTA (Lane Tracing Assist) system. (if equipped)
NOTICE
■Repairing or replacing snow tires

Maintenance and care
WARNING
●Keep hands, clothing and tools away from the moving fan.
●Be careful not to touch the engine, power control unit, radiator, exhaust
manifold, etc. right after driving as they may be hot. Oil and other flu-ids may also be hot.
●Do not leave anything that may burn easily, such as paper and
rags, in the engine compartment.
●Do not smoke, cause sparks or
expose an open flame to fuel or 12- volt battery. Fuel and 12-volt battery fumes are flammable.
●Be extremely cautious when work-ing on the 12-volt battery. It con-
tains poisonous and corrosive sulfuric acid.
●Take care because brake fluid can harm your hands or eyes and dam-age painted surfaces. If fluid gets
on your hands or in your eyes, flush the affected area with clean water immediately.
If you still experience discomfort, consult a doctor.
■When working near the electric cooling fan or radiator grille
Be sure the power switch is OFF.
With the power switch in ON, the electric cooling fan may automatically start to run if the air conditioning is on
and/or the coolant temperature is high. ( P.393)
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc.
from getting in your eyes.
NOTICE
■If you remove the air cleaner fil- ter
Driving with the air cleaner filter removed may cause excessive engine wear due to dirt in the air.
■If the fluid level is low or high
It is normal for the brake fluid level to
go down slightly as the brake pads wear or when the fluid level in the accumulator is high.
If the reservoir needs frequent refill- ing, it may indicate a serious problem.
