WA R N I N G
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When the vehicle is parked
●Do not leave glasses, cigarette lighters, sp
ray cans, or soft drink cans in the vehicle
when it is in the sun.
Doing so may result in the following:
• Gas may leak from a cigarette lighter or spray can, and may lead to a fire.
• The temperature inside the vehicle may cause the plastic lenses and plastic mate- rial of glasses to deform or crack.
• Soft drink cans may fracture, causing the contents to spray over the interior of the vehicle, and may also cause a short circuit in the vehicle’s electrical components.
●Do not leave cigarette lighters in the vehicle. If a cigarette lighter is in a place such as
the glove box or on the floor, it may be lit accidentally when luggage is loaded or the
seat is adjusted, causing a fire.
●Do not attach adhesive discs to the windsh ield or windows. Do not place containers
such as air fresheners on the instrument panel or dashboard. Adhesive discs or con-
tainers may act as lenses, causing a fire in the vehicle.
●Do not leave a door or window open if the curved glass is coated with a metallized
film such as a silver-colored one. Reflected sunlight may cause the glass to act as a
lens, causing a fire.
●Always apply the parking brake, shift the shift position to P, stop the hybrid system and
lock the vehicle.
Do not leave the vehicle unattended while the “READY” indicator is illuminated.
If the vehicle is parked with the shift position in P but the parking brake is not set, the
vehicle may start to move, possibly leading to an accident.
●Do not touch the exhaust pipe while the “R EADY” indicator is illuminated or immedi-
ately after turning the hybrid system off.
Doing so may cause burns.
■When taking a nap in the vehicle
Always turn the hybrid system off. Otherwise, if you accidentally move the shift lever or
depress the accelerator pedal, this could caus e an accident or fire due to hybrid system
overheating. Additionally, if the vehicle is parked in a poorly ventilated area, exhaust
gases may collect and enter the vehicle, lead ing to death or a serious health hazard.

■EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may be heard.
This does not indicate a malfunction.
■Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from overheating
when there is frequent steering input over an extended period of time. The steering
wheel may feel heavy as a result. Should this
occur, refrain from excessive steering input
or stop the vehicle and turn the hybrid system off. The EPS system should return to nor-
mal within 10 minutes.
■Operating conditions of hill-start assist control
When the following four conditions are met, the hill-start assist control will operate:
●The shift position is in a position other than P or N (when starting off forward/backward
on an upward incline).
●The vehicle is stopped.
●The accelerator pedal is not depressed.
●The parking brake is not engaged.
■Automatic system cancelation of hill-start assist control

Hybrid vehicle driving tips
◆Using Eco drive mode
When using Eco drive mode, the torq
ue corresponding to the accelerator
pedal depression amount can be generate d more smoothly than it is in normal
conditions. In addition, the operation of the air conditioning system (heating/
cooling) will be minimized, improving the fuel economy. ( P. 2 3 7 )
◆Use of Hybrid System Indicator
The Eco-friendly driving is possible by keeping the indicator needle of Hybrid
System Indicator within Eco area. ( P. 8 8 )
◆Shift lever operation
Shift the shift position to D when stoppe d at a traffic light, or driving in heavy
traffic etc. Shift the shift position to P when parking. When using the N posi-
tion, there is no positive effect on fuel consumption. In the N position, the gas-
oline engine operates but electricity cannot be generated. Also, when using
the air conditioning system, etc., the hy brid battery (traction battery) power is
consumed.
◆Accelerator pedal/brake pedal operation
●Drive your vehicle smoothly. Avoid ab rupt acceleration and deceleration.
Gradual acceleration and deceleration will make more effective use of the
electric motor (traction motor) wi thout having to use gasoline engine
power.
●Avoid repeated acceleration. Repeated acceleration consumes hybrid bat-
tery (traction battery) power, resulting in poor fuel consumption. Battery
power can be restored by driving with the accelerator pedal slightly
released.
◆When braking
Make sure to operate the brakes gently and in a timely manner. A greater
amount of electrical energy can be retained when slowing down.
For economical and ecological driving, pay attention to the following points:

■Using automatic mode
Fan speed is adjusted automatically accordin g to the temperature setting and the ambi-
ent conditions.
Therefore, the fan may stop for a while until warm or cool air is ready to flow immediately
after the “AUTO” button is pr essed or “AUTO” is selected.
■When the outside temperature exceeds 75 F (24 C) and the air conditioning system
is on
●In order to reduce the air conditioning po wer consumption, the air conditioning system
may switch to recirculated air mode automatically.
This may also reduce fuel consumption.
●Recirculated air mode is selected as a default mode when the power switch is turned to
ON mode.
●It is possible to switch to outside air mode at any time by pressing .
■Fogging up of the windows
●The windows will easily fog up when the humidity in the vehicle is high. Pressing “A/C”
button or selecting “A/C” will dehumidify th e air from the outlets and defog the wind-
shield effectively.
●If you turn “A/C” off, the windows may fog up more easily.
●The windows may fog up if the recirculated air mode is used.
■Outside/recirculated air mode
●When driving on dusty roads such as tunnels or in heavy traffic, set to
the recirculated air mode. This is effective in preventing outside air from entering the
vehicle interior. During cooling operation, setting the recirculated air mode will also
cool the vehicle interior effectively.
●Outside/recirculated air mode may automa tically switch depending on the tempera-
ture setting or the inside temperature.
■When the outside temperature is low
The dehumidification function may not operat e even when “A/C” is pressed or “A/C” is
selected.
■Operation of the air conditioning system in Eco drive mode
●In the Eco drive mode, the air conditioning sy stem is controlled as follows to prioritize
fuel efficiency
• Engine speed and compressor operation controlled to restrict heating/cooling
capacity
• Fan speed restricted when automatic mode is selected
●To improve air conditioning performa nce, perform the following operations
• Adjust the fan speed
• Turn off Eco drive mode
• Customize the air conditioning control of Eco drive mode. (P. 6 0 3 )

■Ventilation and air conditioning odors
●To let fresh air in, set the air conditio ning system to the outside air mode.
●During use, various odors from inside and outside the vehicle may enter into and accu-
mulate in the air conditioning system. This may then cause odor to be emitted from the
vents.
●To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air mode prior to turning the vehicle off.
• The start timing of the blower may be dela yed for a short period of time immediately
after the air conditioning system is started in automatic mode.
