PRIUS_U (OM47668U) U.S.A.
■Conditions in which the gasoline engine may not stop
The gasoline engine starts and stops automatically. However, the followings
are examples of conditions under which the engine may not stop automati-
cally:
● The gasoline engine is warming up.
● The hybrid battery (traction battery) is being charged.
● The hybrid battery (traction battery) temperature is low or high.
● The temperature setting of the air conditioning system is high.
■ Charging the battery
● As the gasoline engine or regenerative brake charges the hybrid battery
(traction battery), the battery does not need to be charged from an
outside source. However, if the vehicle is left parked for a long time the
hybrid battery will slowly discharge. For this reason, be sure to drive \
the
vehicle at least once every several months for at least 30 minutes or 10
miles (16 km). If the hybrid battery becomes fully discharged and you are
unable to jump-start the vehicle with the 12 volt battery, contact your
Toyota dealer.
● If the shift lever is in “N”, the hybrid battery (traction battery) will not be
charged. When driving in heavy traffic, operate the vehicle with the shift
lever in “D” or “B” to avoid discharging the battery.
■ After the 12 volt battery has disch arged or has been changed or
removed
The gasoline engine may not stop even if the vehicle is running on the hybrid
battery (traction battery). If this continues for a few days, contact your Toyota
dealer.

High voltage componentsTake care when handling the hybrid sy stem, as it contains a high volt-
age system (about 650 V at maximum) as well as parts that become
extremely hot when the hybrid system is operating. Obey the caution
