The Virtual Engine Sound System
generates an engine sound for
pedestrians to hear vehicle while at
low speeds in EV mode.
High Voltage Battery Air Intake
Hybrid battery air intake
The hybrid battery air intake is locat-
ed on bottom the rear seats. The air
intake cools down the hybrid battery.
When the hybrid battery air intake is
blocked, the hybrid battery may be
overheated. Do not obstruct the air
intake with any other objects.
Plug-in Hybrid Vehicle
The high-voltage battery air intake is
located on the left side of the rear
seats. The air intake cools down the
high-voltage battery.
When the high-voltage battery air
intake is blocked, the high-voltage
battery may be overheated and the
vehicle performance may become
limited and set a hybrid warning
lamp. Do not obstruct the air intake
with any other objects.OJFHQ015005

Maintenance
✽
✽NOTICE
If you connect unauthorized elec-
tronic devices to the battery, the bat-
tery may be discharged. Never use
unauthorized devices.
Recharging the battery
Your vehicle has a maintenance-free,
calcium-based battery.
If the battery becomes discharged
in a short time (because, for exam-
ple, the headlamps or interior
lamps were left on while the vehi-
cle was not in use), recharge it by
slow charging (trickle) for 10 hours.
If the battery gradually discharges because of high electric load while
the vehicle is being used, recharge
it at 20-30A for two hours.CALIFORNIA PROPO-
