Best past fuel consumption
Average fuel consumption
Displays the average fuel consump -
tion between each reset of the total
av
erage fuel consumption on the
multi-information display.
When resetting, if the total average
fuel consu
mption 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 th at 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 corresponding 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 ge ntly 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 consumpt ion. Check traffic reports before leav -
ing and avoid delays as much as possible. When encountering a delay,
gentl
y release the brake pedal to allow the vehicle to move forward slightly
while avoiding overuse of the accelerato r 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 r
ecirculated 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 impr
oved by avoiding overuse of
the heater.
■ Checking tire inflation pressure
Make sure to check the tire inflatio n 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
r
oads can lead to poor fuel consumptio n. 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 la r
ge 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.

Using the mechanical key
To take out the mechanical key:
Electronic keys: Slide the release
le
ver and take the key out.
Card key: Press the lock release
button and tak
e the key out.
The mechanical key can only be
inserted in one direction, as the key
only has grooves on one side. If the
key cannot be inserted in a lock
cylinder, turn it over and re-attempt
to insert it.
After using the mechanical key,
stor
e it in the electronic key. Carry
the mechanical key together with
the electronic key. If the electronic
key battery is depleted or the entry

you will need the mechanical key. 
(  P. 5 3 3 )
■Card key
●The mechanical key that is stored inside the card key should be used only if a
problem arises, such as when the card key does not operate properly.
●If it is difficult to take out the mechanical key, push down the lock release button
using a pen tip etc. If it is still difficult to pull it out, use a coin etc.
●To store the mechanical key in the card
