501-1. Hybrid system
■ Checking tire inflation pressure Make sure to check the tire inflation pressure frequently.
Improper tire inflation pressure can cause poor fu el consumption.
Also, as snow tires can cause large amounts of friction, their use on dry
roads 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 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.

Before driving 1-6. Refueling
Opening the fuel tank cap The fuel tank of your vehicle has a special structure, which requires a
reduction in fuel tank pressure before refueling. After the opener switch
has been pressed, it will take severa l seconds until the vehicle is ready for
refueling.
■ Before refueling the vehicle
● Turn the “POWER” switch off and close all the doors and win-
dows.
● Confirm the type of fuel. (  P. 121)
■ Opening the fuel tank cap
Press the opener to open the
fuel filler door. The fuel filler door will open
within about 10 seconds of the
switch being pressed. Before
refueling is poss ible, a message
will be shown on the multi-infor-
mation display in the instrument
cluster to indicate the progress
of the fuel filler door opener.
(  P. 7 5 5 )
Turn the fuel tank cap slowly to
open.STEP 1

Before driving ■
When the fuel filler door cannot be opened by pressing the inside switch
Open the back door and li ft the deck board up. (  P. 6 6 4 )
With a compact spare tire only:
Remove the spare tire cover. (  P. 664)
Remove the 12-volt battery cover. (  P. 664)
Install the 12-volt battery cover using the clips. (  P. 6 6 7 )
Using the lever to open the fuel filler door may not allow for an adequate reduction
in fuel tank pressure before refueling. To prevent fuel from spilling out, turn the cap
slowly when removing it.
During refueling, fuel may spill out from the filler opening due to air being dis-
charged from inside the fuel tank. Therefore, fill the fuel tank carefully and slowly.■

■ Average vehicle speed
Displays the average vehicle speed since the function was reset The function can be reset by pushing the “ENTER” switch for longer than
one second when the average vehicle speed is displayed.
■ 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.
When refueling, turn the “POWER” switch off. If the vehicle is refueled
without turning the “POWER” switch off, the display may not be
updated.
■ Tire inflation pressure
Displays inflation pressure of each tire. There is no correlation between
the order of the displayed values and the tire positions. If the inflation pressure of any tire drops a certain amount below the tire infla-
tion pressure value currently memorized in the system, the displayed values
will be highlighted.
It may take a few minutes to display the tire inflation pressure after the
“POWER” switch is turned to ON mode. It may also take a few minutes to
display the tire inflation pressure after inflation pressure has been adjusted.
If the tire pressure warning light is on or flashing, a message describing the
situation will be displayed.

Cleaning and protecting the vehicle exterior
■
Automatic car washes ●
Before washing the vehicle:
•Fold the mirrors.
• Turn off the power back door system.●

operation. This may prevent the vehicle fr om being cleaned properly or result in
damage to the rear spoiler.
■
High pressure car washes
●
Do not allow the nozzles of the car wash to come within close proximity of the
windows.
●
Before using the car wash, check that the fuel filler door on your vehicle is closed
properly.Perform the following to protect the vehicle and maintain it in prime condi-
tion:
● Working from top to bottom, liber ally apply water to the vehicle
body, wheel wells and underside of the vehicle to remove any dirt
and dust.
● Wash the vehicle body using a sponge or soft cloth, such as a
chamois.
● For hard-to-remove marks, use car wash soap and rinse thor-
oughly with water.
