Hybrid system precautions
The illustration is an example for explanation and may differ from the actual item.
There are air intake vents on the both
sides of the rear seatback for the pur-
pose of cooling the hybrid battery
(traction battery). If the vents become
blocked, the hybrid battery may over-
heat, leading to a reduction in hybrid
battery output.
Take care when handling the hybrid system, as it is a high voltage system
(about 650 V at maximum) as well as contains parts that become extremely
hot when the hybrid system is operating. Obey the warning labels attached to
the vehicle.

4-5. Using the driving support systems
Driving mode select switch
Normal mode/Customized mode
Normal mode and customized mode are 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” or “CUSTOMIZE” indicator will be illumi-
nated.
Press the switch to change the driving mode to normal mode when Eco drive mode or
sport mode is selected.
• Normal mode
For normal driving.
• Customized mode
Allows you to drive with the power train, chassis and air conditioning system func-
tions set to your preferred settings.
Customized mode settings can only be changed on the drive mode customization
display of the Remote Touch screen. ( P. 499)
Eco drive mode
Use Eco drive mode to help achieve low fuel consumption during trips that
involve frequent accelerating.
When not in Eco drive mode and the driving mo de select switch is turned to the left,
the “ECO” or “ECO MODE” indicator comes on in the multi- information display.
The driving modes can be selected to suit driving condition.

Sport mode•SPORT S mode
Assists acceleration response by controlling the transmission and engine.
When not in SPORT S mode and the driving mode select switch is turned to the
right, the “SPORT S” indicator comes on in the multi-information display, and the
Hybrid System Indicator changes to the tachometer. ( P. 9 1 )
•SPORT S+ mode
Helps to ensure steering performanc e and driving stability by simulta-
neously controlling the steering and su spension in addition to the hybrid
system. Suitable for sporty driving.
When in SPORT S mode and the driving mode select switch is turned to the right,
the “SPORT S+” indicator comes on in the multi-information display.
■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, per-
form the following operations:
●Turn off eco air conditioning mode ( P. 2 8 7 )
●Adjust the fan speed ( P. 2 8 6 )
●Turn off Eco drive mode
■Automatic operation of the seat heater during Eco drive mode
Eco drive mode controls the he ating operation and fan speed of the air conditioning sys-
tem to enhance fuel efficiency. If the driving mode select switch is switched to Eco drive
mode in cold temperatures, the seat heater wi ll be automatically operated to assist heat-
ing performance.
■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 (12.3-inch display only)
When the driving mode is changed, the selected driving mode will be temporarily dis-
played on the side display. ( P. 2 8 3 )

4-6. Driving tips
Hybrid vehicle driving tips
◆Using Eco drive mode
When using Eco drive mode, the torque 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 5 6 )
◆Use of Hybrid System Indicator
The Eco-friendly driving is possible by keeping the indicate of Hybrid System
Indicator within Eco area. ( P. 9 0 )
◆Shift lever operation
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, wh en using the air conditioning system,
etc., the hybrid battery (traction 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.
For economical and ecological driving, pay attention to the following points:

Driving
◆Delays
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 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 time 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 th e 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 avoiding overuse of the heater.
◆Checking tire inflation pressure
Make sure to check the tire inflation pressure frequently. Improper tire infla-
tion pressure can cause 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.
◆Warming up before driving
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 repeated ly warm up, which can lead to excess
fuel consumption.
