●The buzzer sounds intermittently
when the hybrid battery (traction
battery) remains without charging
while the shift leve r is in N, or the
remaining charge amount drops
below a certain level. If the
remaining charge amount drops
further, the buzzer sounds contin-
uously.
●When a warning message is
shown on the multi-information
display and the buzzer sounds,
follow the instructions displayed
on the screen to p erform trouble-
shooting.

■Updating the history data
Update the latest fuel consumption
by selecting “Upda te” to measure
the current fuel consumption again.
■Resetting the data
The fuel consumption data can be

■Cruising range
Displays the estimated maximum
distance that can be driven with the
quantity of fuel remaining.
This distance is computed based on
your average fuel consumption. As
a result, the actual distance that can
be driven may differ from that dis-

When using Eco drive mode, the
torque corresponding to the
accelerator pedal depression
amount can be generated more
smoothly than it is in normal
conditions. In addition, the oper-
ation of the air conditioning sys-
tem (heating/cooling) will be
minimized, improving the fuel
economy. (P.334)
The Eco-friendly driving is pos-
sible by keeping the indicator of
Hybrid System Indicator within
Eco area. ( P.98, 102)
Shift the shift lever to D when
stopped at a traffic light, or driv-
ing in heavy traffic etc. Shift the
shift lever to P when parking.
When using the N position,
there is no positive effect on fuel
consumption. In the N position,
the gasoline engine operates but electricity cannot be gener-
ated. Also, when using the air
conditioning system, etc., the
hybrid battery (traction battery)
power is consumed.

Drive your vehicle smoothly.
Avoid abrupt acceleration and
deceleration. Gradual accel-
eration and deceleration will
make more effective use of
the electric motor (traction
motor) without having to use
gasoline engine power.
 Avoid repeated acceleration.
Repeated acceleration con-
sumes hybrid battery (trac-
tion battery) power, resulting
in poor fuel consumption. Bat-
tery power can be restored by
driving with the accelerator
pedal slightly released.
Make sure to operate the brakes
gently and in a timely manner. A
greater amount of electrical
energy can be regenerated
when slowing down.
Repeated acceleration and
deceleration, as well as long
waits at traffic lights, will lead to
bad fuel economy. Check traffic

reports before leaving and avoid
delays as much as possible.
When driving in a traffic jam,
gently release the brake pedal
to allow the vehicle to move for-
ward slightly while avoiding
overuse of the accelerator
pedal. Doing so can help control
excessive gasoline consump-
tion.
Control and maintain the vehicle
at a constant speed. Before
stopping at a toll booth or simi-
lar, allow plenty of time to
release the accelerator and gen-
tly apply the brakes. A greater
amount of electrical energy can
be regenerated when slowing
down.
Use the air conditioning only
when necessary. Doing so can
help reduce excessive gasoline
consumption.
In summer: When the ambient
temperature is high, use the
recirculated air mode. Doing so
will help to reduce the burden on
the air conditioning system and
reduce fuel consumption as
well.
In winter: Because the gasoline
engine will not automatically cut
out until it and the interior of the
vehicle are warm, it will con-sume fuel. Also, fuel consump-
tion can be improved by
avoiding overuse of the heater.
Make sure to check the tire infla-
tion pressure frequently.
Improper tire inflation pressure
can cause poor fuel economy.
Also, as snow tires can cause
large amounts of friction, their
use on dry roads can lead to
poor fuel economy. Use tires
that are appropriate for the sea-
son.
Carrying heavy luggage will lead
to poor fuel economy. Avoid car-
rying unnecessary luggage.
Installing a large roof rack will
also cause poor fuel economy.
Since the gasoline engine starts
up and cuts out automatically
when cold, warming up the
engine is unnecessary. More-
over, frequently driving short
distances will cause the engine
to repeatedly warm up, which
can lead to excess fuel con-
sumption.

3505-1. Using the air conditioning system and defogger
switch.
■Defogging the rear window
and outside rear view mir-
rors (if equipped), and de-
icing windshield wipers (if
equipped)
Defoggers are used to defog the
rear window and to remove rain-
drops, dew and frost from the
outside rear view mirrors (if
equipped).
The windshield wiper de-icer is
used to prevent ice from building
up on the windshield and wiper
blades.
Press the rear window defog-
ger/outside rear view mirror
defoggers /windshield wiper de-
icer switch.
The defoggers and windshield
wiper de-icer will automatically turn
off after 15 minutes.
When the rear window defog-
ger/outside rear v iew mirror defog-
gers /windshield wiper de-icer
switch is on, the indicator illumi-
nates on the switch.
■Eco air conditioning mode
The air conditioning is controlled
with low fuel consumption priori-
tized such as reducing fan
speed, etc.
Select the eco air conditioning
mode switch on the control
screen. ( P.352)
When the eco air conditioning
mode is on, the indicator illumi-
nates on the eco air conditioning mode switch.
■Fogging up of the windows
●The windows will
easily fog up
when the humidity in the vehicle is
high. Turning “A/C” switch on will
dehumidify the air from the outlets
and defog the windshield effec-
tively.
●If you turn “A/C” switch off, the
windows may fog up more easily.
●The windows may fog up if the
recirculated air mode is used.
■When driving on dusty roads
Close all windows. If dust thrown up
by the vehicle is still drawn into the
vehicle after closing the windows, it
is recommended that the air intake
mode be set to outside air mode
and the fan speed to any setting
except off.
■Outside/recirculated air mode
●Setting to the recirculated air
mode temporarily is recom-
mended in preventing dirty air
from entering the vehicle interior
and helping to c ool the vehicle
when the outside air temperature
is high.
●Outside/recirculated air mode may
automatically switch depending on
the temperature setting or the
inside temperature.
■When the outside temperature
exceeds 75°F (24°C) and the air
conditioning system is on
●In order to reduce the air condi-
tioning power consumption, the air
conditioning system may switch to
recirculated air mode automati-
cally. This may also reduce fuel
consumption.
●Recirculated air mode is selected
as a default mode when the power
switch is turned to ON.
●It is possible to switch to outside
air mode at any time by pressing
the outside/recirculated air mode
