UK_AURIS_HV_EE
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 out-
side 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 16
km (10 miles). If the hybrid battery becomes fully discharged and you are
unable to jump-start the vehicle with the 12-volt battery, contact any
authorized Toyota dealer or repairer, or another duly qualified and
equipped professional.
If the shift position is in N, the hybrid battery (traction battery) will not be
charged. When driving in heavy traffic, operate the vehicle with the shift
position in D or B to avoid discharging the battery.
After the 12-volt battery has discharged 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 any autho-
rized Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional.

Starting the hybrid system when the 12-volt battery is discharged
The hybrid system cannot be started by push-starting.
Avoiding a discharged 12-volt battery
Turn off the headlights and the audio system while the hybrid system is
turned off.
Turn off any unnecessary electrical components when the vehicle is run-
ning at a low speed for an extended period, such as in heavy traffic, etc.
When the 12-volt battery is removed or discharged
If the 12-volt battery is depleted with the shift position in P, it will not be
possible to shift out of P. In this case, the vehicle cannot be towed without
lifting both front wheels because the front wheels are locked by the park-
ing lock. (P. 423)
The hybrid system may not start. (P. 384)
Once the hybrid system has started, remove the jumper
cables in the exact reverse order in which they were con-
nected.
Close the exclusive jump starting terminal cover and rein-
stall the fuse box cover.
Once the hybrid system starts, have the vehicle checked at any
authorized Toyota dealer or repairer, or another duly qualified and
equipped professional, as soon as possible.STEP7

NOTICE
When handling jumper cables
Be careful that the jumper cables do not become tangled in the cooling fan
or any of the belts when connecting or disconnecting them.
Exclusive jump starting terminal precaution
The exclusive jump starting terminal is to be used when charging the 12-volt
battery from another vehicle in an emergency. It cannot be used to jump start
another vehicle.
