Select and press the “ENTER” button.
If the screen does not appear, select and
press the “ENTER” button.
Best past fuel consumption
Average fuel consumption
Displays the average fuel consump-
tion between each reset of the total
average fuel consumption on the
multi-information display.
When resetting, if the total average
fuel consumption is better than the
best past fuel consumption, the best
past fuel consumption will be
updated.
These images are examples only, and may vary slightly from actual conditions.
■Resetting the consumption data
Selecting on the screen will reset the average fuel consump-
tion. Selecting on the screen will reset the past records.
Selecting will confirm resetting of all the data (except cruising range).
■Cruising range
Displays the estimated maximum distance that can be driven with the quantity of
fuel remaining.
This distance is computed based on your average fuel consumption.
As a result, the actual distance that can be driven may differ from that displayed.

Hybrid vehicle driving tips
For economical and ecological driving, pay attention to the following
points:
■Using Eco Mode
When using Eco mode, the torque corre sponding to the accelerator pedal
depression amount can be generated more smoothly than it is in normal
conditions. In addition, the operation of the air conditioning system will be
minimized, improving the fuel economy.
( → P. 1 5 5 )
■Use of Hybrid System Indicator
The environmentally-friendly driving is possible by keeping the indicate of
Hybrid System Indicator within Eco area. ( →P. 1 6 4 )
■When braking the vehicle
Make sure to operate the brakes gently and in good time. A greater
amount of electrical energy can be retained when slowing down.
■Delays
Repeated acceleration and deceleration, as well as long waits at traffic
lights, will lead to bad fuel consumption. Check traffic reports before leav-
ing and avoid delays as much as po ssible. When encountering a delay,
gently release the brake pedal to allow the vehicle to move forward slightly
while avoiding overuse of the accelera tor pedal. Doing so can help control
excessive gasoline consumption.
■ Highway driving
Control your speed and keep at a constant speed. Also, 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
retained when slowing down.

■Air conditioning
Use the air conditioning only when necessary. Doing so can help control
excessive gasoline consumption.
In summer: In high temperatures, use the recirculated air mode. Doing so
will help to reduce the burden on the air conditioner and reduce fuel con-
sumption as well.
In winter: Because the gasoline engine will not automatically cut out until
the gasoline engine and the interior of the vehicle are warm, it will con-
sume fuel. Also, fuel consumption can be improved by avoiding overuse of
the heater.
■ Checking tire inflation pressure
Make sure to check the tire inflation pressure frequently. Improper tire
inflation pressure can cause poor fuel consumption.
Also, as snow tires can cause large amounts of friction, their use on dry
roads can lead to poor fuel consumption. Use a tire that is appropriate for
the season.
■Luggage
Carrying heavy luggage can lead to poor fuel consumption. Avoid carry-
ing unnecessary luggage. Installing a large roof rack can also cause poor
fuel consumption.
■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
distances will cause the engine to repeatedly warm up, which can lead to
poor fuel consumption.

■ Total distance/Total average fuel consumption
Displays the total distance and average fuel consumption since the last
reset.
Press the “ENTER” switch for 1 second or more when the total distance and
the average fuel consumption is displayed.
“Past Record” screen on the navigation system (if equipped) will also be
reset. ( →P. 3 6 )
■Current fuel consumption/Average fuel consumption after refueling
Displays the instant fuel consumption and average fuel consumption
after refueling.
■ Cruising range
Displays the estimated maximum distan ce that can be driven with the
quantity of fuel remaining.
• This distance is computed based on your average fuel consumption. As a result, the actual distance that can be driven may differ from that dis-
played.
• When only a small amount of fuel is added to the tank, the display may not be updated.

■Outside temperature display
In the following situations, the correct outside temperature may not be displayed, or
the display may take longer than normal to change.
●When stopped, or driving at low speeds (less than 15 mph [25 km/h])
●When the outside temperature has changed suddenly (at the entrance/exit of a
garage, tunnel, etc.)
■When disconnecting and reconnecting battery terminals
The following information will be reset:
●Total distance/Total average fuel consumption
●Average fuel consumption after refueling
●Cruising range
●Average vehicle speed
■Customization
Settings (e.g. available languages) can be changed.
(Customizable features →P. 5 74 )
CAUTION
■Caution while driving
When operating the electronic feature control while driving, take extra notice of the
vehicle’s surrounding area.
NOTICE
■The multi-information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal informa-
tion display. At extremely low temperatures, the information display monitor may
respond slowly, and display changes may be delayed.
