COMPONENTS OF THE HYBRID/PLUG-IN HYBRID VEHICLE (CONT.)
Safety plugSome Special Features of the
Hybrid Vehicle.
Hybrid vehicles sound different than
gasoline engine vehicles. When the
hybrid system operates, you may
hear a sound from the hybrid battery
system behind the rear seat. If you
apply the accelerator pedal rapidly,
you may hear a sound. When you
apply the brake pedal, you may hear
a sound from the regenerative brake
system. When the hybrid system is
turned off or on, you may hear a
sound in the engine compartment. If
you depress the brake pedal repeat-
edly when the hybrid system is
turned on, you may hear a sound in
the engine compartment. None of
these sounds indicate a problem.
They are characteristics of hybrid
vehicles.
When the hybrid system is turned on,
the engine may run. This does not
indicate a malfunction. If the “ ”
symbol is on, the hybrid system is
operating. Even if the gasoline engine
is off, you can operate the vehicle.The HEV system may emit electromag-
netic waves which can affect the per-
formance of electronic devices appli-
ances, such as laptop computers,
which are not part of the vehicle design.
If you park the vehicle for a long time,
the hybrid system will discharge. You
need to drive the vehicle several times
per month to maintain a charge.
When you start the hybrid system in
the "P" transmission position, the
“ ” symbol is illuminated in the
cluster. The driver can drive the vehi-
cle even if the engine is stopped.

procedure in service manual.
WARNING- Turning off HEV system
When you leave the vehicle, you
should turn off the hybrid sys-
tem. If you depress the accelera-
tor pedal by mistake and the vehi-
cle is not in the "P" position, the
vehicle will accelerate. This may
result in serious injury or death.

(VESS)
The Virtual Engine Sound System
generates a simulated engine sound
for pedestrians to hear the 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 at the bottom the rear seats.
The air intake cools down the hybrid
battery.
When the hybrid battery air intake is
blocked, the hybrid battery may over-
heat. 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 overheat and the vehicle
performance may become limited
and set a hybrid warning lamp. Do
not obstruct the air intake with any
other objects.OJFHQ015005

Avoid the engine compartment.
Avoid making contact with anyorange or high voltage wires,
cables, or components.
Assume that a high voltage com- ponent is exposed and move away
from the vehicle as promptly as
possible.
Refer to Chapter 6 for towing infor- mation.
✽ ✽ NOTICE
• If a small scale fire occurs, use a
fire extinguisher rated ABC or BC
for electrical fires.
If it is impossible to extinguish the
fire in the early stage, remain a
safe distance from the vehicle and
immediately call 911. Also, advise
them that a hybrid vehicle is
involved.
If the fire spreads to the high volt-
age battery, large amount of water
is needed to put out the fire.
Using small amount of water or
fire extinguishers not meant for
electrical fires could cause serious
injury or death from electrical
shocks.
• If you need towing, refer to chap- ter 6.WARNING - Air Intake
Blocking the air intake behind the rear seats may damage
the HEV battery.
Do not allow any water to enter cleaning. If any water
enters the air intake, the
Hybrid battery may cause an
electric shock which can
cause serious injury or death
due to electrocution.
