Normal mode/Customized mode
Normal mode and customized mode ar e selected by pressing the driving
mode select switch. Each time the switch is pressed, the driving mode
changes between normal mode and customized mode. When customized
mode is selected, the “CUSTOMIZE” indicator will be illuminated.
When Eco drive mode or sport mode is se lected, pressing the switch changes the driving mode to normal mode.
• Normal mode
Provides an optimal balance of fuel economy, quietness, and dynamic per-
formance. Suitable for city driving.
• Customized mode
Allows you to drive with the following functions set to your preferred set-
tings.
Customized mode settings can on ly be changed on the drive mode
customization display of the audio system screen.

Eco drive mode
Helps the driver accelerate in an eco-fr iendly manner and improve fuel econ-
omy through moderate throttle charact eristics and by controlling the opera-
tion of the air conditioning system (heating/cooling).
When not in Eco drive mode, if the driving mode select switch is turned to the left, the
Eco drive mode indicator will come on.
Sport mode
•SPORT S mode
Controls the hybrid system to prov ide quick, powerful acceleration. This
mode is suitable for when agile drivin g response is desired, such as when
driving on roads with many curves.
When not in sport mode and the driving mode select switch is turned to the right, the “SPORT” indicator comes on, and the hy brid system indicator changes to the
tachometer. ( P. 105)
•SPORT S+ mode
Helps to ensure steering performanc e and driving stability by simultane-
ously controlling the steering and suspension in addition to the hybrid sys-
tem. Suitable for sportier driving.
When in SPORT S mode, if the driving mode select switch is turned to the right, the “SPORT S+” indicator will come on.

■Operation of the air conditioning system in Eco drive mode
Eco drive mode controls the heating/cooling operations and fan speed of the air condi-
tioning system to enhance fuel efficiency. To improve air conditioning performance, adjust the fan speed or turn off Eco drive mode.
■Automatic deactivation of sport mode and customized mode
If the power switch is turned off after driv ing in sport mode or customized mode, the drive mode will be changed to normal mode.
■Driving mode pop-up display (veh icles with a 10.3-inch display)
When the driving mode is changed, the sele cted driving mode will be temporarily dis- played on the side display. ( P. 464)

4-6. 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, im proving the fuel economy. (P. 348)
◆Use of Hybrid System Indicator
The Eco-friendly driving is possible by keeping the indicator needle (except F
SPORT models) or bar display (F SPOR T models) of Hybrid System Indicator
within the Eco area. ( P. 109)
◆Shift lever operation
Shift the shift lever to D wh en 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 genera ted. Also, when using the air conditioning system,
etc., the hybrid battery (tractio n battery) power is consumed.
◆Accelerator pedal/brake pedal operation
●Drive your vehicle smoothly. Avoid abrupt acceleration and deceleration.
Gradual acceleration and deceleration will make more effective use of the
electric motor (traction motor) withou t 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 regenerated when slowing down.
Hybrid vehicle driving tips
For economical and ecological driving, pay attention to the following points:

◆Delays
Repeated acceleration and deceleration, as well as long waits at traffic lights,
will lead to bad fuel economy. Check tr affic reports before leaving and avoid
delays as much as possible. When drivin g in a traffic jam, gently release the
brake pedal to allow the vehicle to move forward slightly while avoiding over-
use of the accelerator pedal. Doing so can help control excessive gasoline
consumption.
◆Highway driving
Control and maintain the vehicle at a co nstant speed. Before stopping at a toll
booth or similar, allow plenty of ti me to release the accelerator and gently
apply the brakes. A greater amount of electrical energy can be regenerated
when slowing down.
◆Air conditioning
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 consume fuel. Also, fuel con-
sumption can be improved by av oiding overuse of the heater.
◆Checking tire inflation pressure
Make sure to check the tire inflation pr essure frequently. Improper tire infla-
tion pressure can caus e poor fuel economy.
Also, as snow tires can cause large amou nts of friction, their use on dry roads
can lead to poor fuel economy. Use ti res that are appropriate for the season.
◆Luggage
Carrying heavy luggage will lead to poor fuel economy. Avoid carrying
unnecessary luggage. Installing a large roof rack will also cause poor fuel
economy.
