The Virtual Engine Sound System gen‐
erates 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 located
on the bottom of the rear seats. The air intake cools down the hybrid bat‐
tery. When the hybrid battery air in‐
take is blocked, the hybrid battery may be overheated. Do not obstruct the air
intake with any other objects.
Plug-in Hybrid Vehicle
0+')1-
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 in‐
take is blocked, the high-voltage bat‐ tery may be overheated and the vehicle
performance may become limited and
set a hybrid warning lamp. Do not ob‐ struct the air intake with any other ob‐
jects.
WARNING
nAir Intake
•Blocking the air intake behind therear seats may damage the HEVbattery.
•Do not allow any water into the airintake even when cleaning. If anywater enters the air intake, theHybrid battery may cause an elec‐tric shock which can cause seriousinjury or death due to electrocu‐tion.
If an accident occurs
• Avoid the engine compartment.
• Avoid any orange or high voltage wires, cables, or components.
• Assume that a high voltage compo‐ nent is exposed and move away fromthe vehicle as promptly as possible.
• Refer to L

1. Gasohol containing more than 10%ethanol.
2. Gasoline or gasohol containing methanol.
3. Leaded fuel or leaded gasohol.
CAUTION
Never use gasohol which containsmethanol. Discontinue use of anygasohol product which impairs driva‐bility.
Other fuels
Using fuels such as - Silicone (Si) contained fuel,
- MMT (Manganese, Mn) contained
fuel,
- Ferrocene (Fe) contained fuel, and
- Other metalic additives contained
fuels, may cause vehicle and engine
damage or cause plugging, misfiring,
poor acceleration, engine stalling, catalyst melting, abnormal corrosion,
life cycle reduction, etc.
Also, the Malfunction Indicator Lamp
(MIL) may illuminate.
NOTICE

ing MTBE (Methyl Tertiary Butyl Ether) over 15.0% vol. (Oxygen Content 2.7%
weight) in your vehicle.
Fuel containing MTBE over 15.0% vol.
(Oxygen Content 2.7% weight) may re‐ duce vehicle performance and produce
vapor lock or hard starting.
CAUTION
Your New Vehicle Limited Warrantymay not cover damage to the fuelsystem and any performance prob‐lems that are caused by the use offuels containing methanol or fuelscontaining MTBE (Methyl TertiaryButyl Ether) over 15.0% vol. (OxygenContent 2.7% weight.)
Do not use methanol
Fuels containing methanol (wood alco‐ hol) should not be used in your vehicle.
