When driving
■
Operation of the air conditio ning system in Eco drive mode
Eco drive mode controls the heating/cooling operations and fan speed of the
air conditioning system to enhance fuel efficiency. ( P. 242) To improve air
conditioning performance, adjust the temperature setting or fan speed, or
turn off Eco drive mode.
■ When in heavy traffic
If the shift lever is in N, the hybrid battery (traction battery) will not be
charged. To help prevent the battery from discharging, avoid putting the shift
lever in N for an extended period of time.
■ If the shift lever cannot be shifted from P
P. 471
CAUTION
■When driving on slippery road surfaces
Do not accelerate or shift gears suddenly.
Sudden changes in engine braking may cause the vehicle to spin or skid,
resulting in an accident.

■“ECO Score”
Hybrid battery (traction battery) charge level display
EV drive indicator lamp
Illuminates when only the electric motor is used to drive the vehicle
Hybrid System Indicator
Hybrid System Indicator represents the hybrid system power output and
regenerative charging. ( P. 195)
Eco driving conditions display
Driving conditions are displayed in 5 stages and divided into 3 categories:
start, cruise and stop. Every time the vehicle is stopped, the score is dis-
played. (Every time the vehicle is accelerated the score that was last dis-
played is reset. Accumulative scores are not calculated.)

When driving
Hybrid System Indicator
Charge area
Shows energy regeneration* status. Regenerated energy will be used to
charge the hybrid battery (traction battery).
*: When used in this manual, “regeneration” refers to the conversion ofenergy created by the movement of the vehicle into electrical energy.
Hybrid Eco area
Shows that gasoline engine power is not being used very often.
The gasoline engine will automatically stop and restart under various con-
ditions.
Eco area
Shows that the vehicle is being driven in an Eco-friendly manner.
Power area
Shows that the driving power is more than the upper limit of Eco driving.
(during full power driving etc.)
Keeping the indicator within Eco area can help Eco-friendly driving.

200 2-2. Instrument cluster
■The clock is displayed when
Vehicles without a smart key system
The engine switch is in the “ON” position.
Vehicles with a smart key system
The “POWER” switch is in ON mode.
■ Eco score
●As the accelerator pedal is not depressed, the driven distance using
cruise control (if equipped) is not included in the eco score.
● As the eco score evaluation differs according to driving conditions and
environmental factors, in some cases it may not be linked to fuel con-
sumption.
■ Eco savings
●Fuel cost and savings should be used as a guide only.
● Depending on refueling methods, driving conditions and environmental
factors, the actual and displayed fuel costs may differ.
● In some cases, fuel cost and savings may not be linked to the eco score
evaluation.
■ When disconnecting and reconnect ing 12-volt battery terminals
The following information data will be reset:
● Clock
● Past record (aside from the top 3 results)
● Average fuel consumption
● Cruising range
● Average vehicle speed
● Driving time
● EV driving rate/EV driven distance
Additionally, some displays may return to their default settings.
■ Liquid crystal display
Small spots or light spots may appear on the display. This phenomenon is
characteristic of liquid crystal displays, and there is no problem continuing to
use the display.

204 2-3. Operating the lights and wipers
■Daytime running light system
●To make your vehicle more visible to other drivers, the headlights turn on
automatically (at a reduced intensity) whenever the hybrid system is
started and the parking brake is released. Daytime running lights are not
designed for use at night.
For type A: Daytime running lights can be turned off by operating the
switch.
● Compared to turning on the headlights, the daytime running light system
offers greater durability and consumes less electricity, so it can help
improve fuel economy.
■ Light reminder buzzer
Vehicles without a smart key system
A buzzer sounds when the engine switch is turned to the “LOCK” or “ACC”
position and the driver's door is opened while the lights are turned on.
Vehicles with a smart key system
A buzzer sounds when the “POWER” switch is turned off or turned to
ACCESSORY mode and the driver's door is opened while the lights are
turned on.
■ Battery-saving function
In the following conditions, the remaining lights will go off automatically after
20 minutes in order to prevent the vehicle battery from being discharged:
●The headlights and/or tail lights are on.
● The engine switch is turned to the “ACC” or “LOCK” position (vehicles
without a smart key system) or the “P OWER” switch is turned to ACCES-
SORY mode or turned off (vehicles with a smart key system).
This function will be canceled in any of the following situations:
● When the engine switch is turned to the “ON” position (vehicles without a
smart key system) or the “POWER” switch is turned to ON mode (vehi-
cles with a smart key system).
● When the light switch is operated.
● When the door is opened or closed.

Winter driving tips
Carry out the necessary preparations and inspections before driving
the vehicle in winter. Always drive the vehicle in a manner appropri-
ate to the prevailing weather conditions.
■ Pre-winter preparations
●Use fluids that are appropriate to the prevailing outside tem-
peratures.
• Engine oil
• Engine/power control unit coolant
• Washer fluid
● Have a service technician inspec t the condition of the 12-volt
battery.
● Have the vehicle fitted with four snow tires or purchase a set
of tire chains for the front tires.
Ensure that all tires are the same size and brand, and that chains
match the size of the tires.
■Before driving the vehicle
Perform the following according to the driving conditions:
●Do not try to forcibly open a window or move a wiper that is
frozen. Pour warm water over the frozen area to melt the ice.
Wipe away the water immediately to prevent it from freezing.
● To ensure proper operation of th e climate control system fan,
remove any snow that has accumulated on the air inlet vents
in front of the windshield.
● Check for and remove any excess ice or snow that may have
accumulated on the exterior li ghts, vehicle's roof, chassis,
around the tires or on the brakes.
● Remove any snow or mud from the bottom of your shoes
before getting in the vehicle.

■ When operating the steering switches
P. 186
CAUTION
■To prevent the windshield from fogging up
Do not use 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.
NOTICE
■To prevent 12-volt battery discharge
Do not leave the air conditioning system on longer than necessary when the
hybrid system is off.

Scanning radio stations
■ Scanning the preset radio stations
Press and hold until you hear a beep.
Preset stations will be played for 5 seconds each.
When the desired station is reached, press again.
■ Scanning all the radio stations within range
Press .
All the stations with reception will be played for 5 seconds each.
When the desired station is reached, press again.
■ When the 12-volt battery is disconnected
Preset stations are erased.
■ Reception sensitivity
●Maintaining perfect radio reception at all times is difficult due to the con-
tinually changing position of the antenna when driving, differences in sig-
nal strength and surrounding objects, such as trains, transmitters, etc.
● When is used, automatic station selection may not be possi-
ble.
● The radio antenna is mounted on the rear roof. The antenna can be
removed from the base by turning it.
NOTICE
■To prevent damage, remove the antenna in the following cases.
●The antenna will touch the ceiling of a garage.
● A car cover will be put on the roof.
