1-4. Hybrid system
■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.377) 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 5.8 L [1.6 gal., 1.3 Imp. gal.] [vehicles without rear wiper] or 6.3 L [1.7 gal., 1.4 Imp. gal.]
[vehicles with rear wiper] when the vehi- cle 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.
●Do not touch the high voltage parts, cables and connectors.
