■ 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.

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.

When the TRAC/VSC/ABS/hill-start assist control systems are
operatingThe slip indicator light will flash
while the TRAC/VSC/ABS/hill-
start assist control systems are
operating.
The stop lights and high mounted
stoplight turn on when the hill-
start assist control system is

■Sounds and vibrations caused by the ABS, brake assist, TRAC and
VSC systems
●A sound may be heard from the engine compartment when the hybrid
system is started or just after the vehicle begins to move, if the brake
pedal is depressed forcefully or repeatedly, or 1 - 2 minuets after the
hybrid system is stopped. This sound does not indicate that a malfunc-
tion has occurred in any of these systems.
● Any of the following conditions may occur when the above systems are
operating. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
■ EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may
be heard. This does not indicate a malfunction.
■ Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from
overheating when there is frequent steering input over an extended period of
time. The steering wheel may feel heavy as a result. Should this occur,
refrain from excessive steering input or stop the vehicle and turn the hybrid
system off. The EPS system should return to normal within 10 minutes.

When driving
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.

Interior features
■Outside/recirculated air mode
●When driving on dusty roads such as tunnels or in heavy traffic, set the
outside/recirculated air mode button to the recirculated air mode. This is
effective in preventing outside air from entering the vehicle interior. Dur-
ing cooling operation, setting the recirculated air mode will also cool the
vehicle interior effectively.
● Outside/recirculated air mode may automatically switch depending on
the temperature setting or the inside temperature.
■ When the outside temperature exceeds 75 F (24C) and the air condi-
tioning system is on
● In order to reduce the air conditioning power consumption, the air condi-
tioning system may switch to recirculated air mode automatically. This
may also reduce fuel consumption.
● Recirculated air mode is selected as a default mode when the engine
switch is turned to the “ON” position (vehicles without a smart key sys-
tem) or the “POWER” switch is turned to ON mode (vehicles with a smart
key system).
● It is possible to switch to outside air mode at any time by pressing
.
■ When the outside temperature falls to nearly 32 F (0 C)
The dehumidification function may not operate even when is
pressed.
■ Air conditioning odors
●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 outside 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 conditioning system is started in automatic
mode.
