When using Eco drive mode, the
torque corresponding to the accelera-
tor pedal depression amount can be
generated more smoothly than it is in
normal conditions. In addition, the
operation of the air conditioning sys-
tem (heating/cooling) will be mini-
mized, improving the fuel economy.

Shift the shift lever to D when stopped
at a traffic light, or driving in heavy traf-
fic etc. Shift the shift lever to P when
parking. When using the N, there is no
positive effect on fuel consumption. In
the N, the gasoline engine operates
but electricity cannot be generated.
Also, when using the air conditioning
system, etc., the hybrid battery (trac-
tion battery) power is consumed.



Drive your vehicle smoothly. Avoid
abrupt acceleration and decelera-
tion. Gradual acceleration and
deceleration will make more effec-
tive use of the electric motor (trac-
tion motor) without having to use
gasoline engine power.



Avoid repeated acceleration.
Repeated acceleration consumes
hybrid battery (traction battery)
power, resulting in poor fuel con-
sumption. Battery power can be
restored by driving with the acceler-
ator pedal slightly released.

Make sure to operate the brakes gen-
tly and in a timely manner. A greater
amount of electrical energy can be
regenerated when slowing down.

Repeated acceleration and decelera-
tion, 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 forward slightly while
avoiding overuse of the accelerator
pedal. Doing so can help control
excessive gasoline consumption.

4-6. Driving tips

Driving

Control and maintain the vehicle at a
constant speed. Before stopping at a
toll booth or similar, allow plenty of
time to release the accelerator and
gently 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 tem-
perature is high, use the recirculated
air mode. Doing so will help to reduce
the burden on the air conditioning sys-
tem 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 consume fuel. Also, fuel consump-
tion can be improved by avoiding
overuse of the heater.

Make sure to check the tire inflation
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
season.

Carrying heavy luggage will lead to
poor fuel economy. Avoid carrying
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.
Moreover, frequently driving short dis-
tances will cause the engine to repeat-
edly warm up, which can lead to excess
fuel consumption.

Ventilation and air conditioning odors

●

To let fresh air in, set the air conditioning

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.

●

ring, the start timing of the blower may be

delayed for a short period of time imme-

diately after the air conditioning system is

started in automatic mode.

●

When parking, the system automatically

switches to fresh air intake mode to

encourage better air circulation through-

out the vehicle, helping to reduce odors

that occur when starting the vehicle.

WARNING

■

To prevent the windshield from fog-

ging up

Do not use the windshield defogger

switch during cool air operation in

extremely humid weather. The difference

between the temperature of the outside

air and that of the windshield can cause

the outer surface of the windshield to fog

up, blocking your vision.

■

When the outside rear view mirror

defoggers are operating

Do not touch the outside rear view mir-

ror surfaces, as they can become very

hot and burn you.

even when the heater is on due to sunlight.

■

Windshield fog detection function

When automatic mode is set, the humidity

sensor detects fog on the windshield and

controls the air conditioning system to pre-

vent fog.

■

Automatic mode for air intake control

In automatic mode, the system detects

exhaust gas and other pollutants and auto-

matically switches between outside air and

recirculated air modes.
When the dehumidification function is off,

and the fan is operating, turning automatic

mode on will activate the dehumidification

function. The next time the dehumidification

function is turned off, the automatic mode

for switching between outside air and recir-

culated air modes is canceled.

This function automatically controls the
air conditioning airflow so that priority
is given to the front seats. When the
front passenger seat is not occupied,
airflow may switch to only the driver’s
seat. Unnecessary air conditioning is
suppressed, contributing to increased
fuel efficiency.
Front seat concentrated airflow mode
operates in the following situations.



No passengers are detected in the
rear seats



The windshield defogger is not
operating

While operating, the indicator on the
switch will turn on.
