4-6.Driving tips
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.308)
Eco-friendly driving is possible
by keeping the Hybrid System
Indicator within the Eco area.
( P. 8 8 )
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 N, there is no posi-
tive effect on fuel consumption.
In N, the gasoline engine oper-
ates but electricity cannot be
generated. 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.

Driving
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.

■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 air mode switch.
■Fogging up of the windows
●The windows will easily fog up
when the humidity in the vehicle is
high. Turning “A/C” on will dehu-

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 r ecirculated 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.
■Operation of the air condition-
ing system in Eco drive mode
●In Eco drive mode, the air condi-
tioning system is controlled as fol-
lows to prioritize fuel efficiency:
• Engine speed and compressor operation controlled to restrict
heating/cooling capacity
• Fan speed restr icted when auto-
matic mode is selected
●To improve air co nditioning perfor-
mance, perform the following
operations:
• Adjust the fan speed
• Turn off Eco drive mode ( P.308)
■When the outside temperature
is low
The dehumidification function may
not operate even when the “A/C”
switch is pressed.
■Ventilation and air conditioning
odors
●To let fresh air in, set the air condi-
tioning system to the outside air
mode.
●During use, various odors from
inside and outside the vehicle may enter into and accumulate 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 out-
side air mode prior to turning the
vehicle off.
• The start timing of the blower may
be delayed for a short period of
time immediately after the air con-
ditioning system is started in auto-
matic mode.
●When parking, the system auto-
matically switches to outside air
mode to encourage better air cir-
culation throughout the vehicle,
helping to reduce odors that occur
when starting the vehicle.
