Driving
■Reverse warning buzzer
When shifting into R, a buzzer will sound to inform the driver that the shift
position is in R.
■ Restraining sudden start (Drive-Start Control)
P. 316
■ Automatic P position selection function
●If the power switch is on and the shift position is not already P, completely
stopping the vehicle and pressing the power switch causes the s hift position
to automatically switch to P and the power switch to turn off.
*
● The shift position may also automatically switch to P if one of the following
conditions is detected while the vehicle is stopped by dynamic radar cruise
control with full-speed range.
• Driver’s seat belt is not fastened
• Driver’s door is opened
• Approximately 3 minutes elapse after the vehicle stopped
*: If the power switch is pressed when driving at very low speeds (for exam-
ple, just before the vehicle stops), the shift position may automatically
switch to P. Press the power switch after completely stopping t he vehicle to
prevent unexpected sudden stopping of the vehicle.
■ If the shift position cannot be shifted from P
There is a possibility that the 12-volt battery is discharged. Check the 12-volt
battery in this situation. ( P. 701)
■ About engine braking
When shift position B is selected, releasing the accelerator pe dal will apply
engine braking.
● When the vehicle is driven at high speeds, compared to ordinary gasoline-
fueled vehicles, the engine braking deceleration is felt less t han that of other
vehicles.
● The vehicle can be accelerated even when shift position B is se lected.
If the vehicle is driven continuously in the B position, fuel e fficiency will
become low. Usually, select the D position.
■ After recharging/reconnecting the 12-volt battery

Driving
■Daytime running light system
●The daytime running lights illuminate using the same lights as the head-
lights, and illuminate dimmer than the headlights.
● To make your vehicle more visible to other drivers during dayti me driving,
the daytime running lights turn on automatically when all of the following
conditions are met. (The daytime running lights are not designe d for use at
night.)
• The hybrid system is operating
• The parking brake is released
• The headlight switch is in the (Canada only), , or
* position
*: When the surroundings are bright
The daytime running lights remain on after they illuminate, eve n if the park-
ing brake is set again.
● For the U.S.A.: Daytime running lights can be turned off by ope rating the
switch.
● Compared to turning on the headlights, the daytime running ligh t system
offers greater durability and consumes less electricity, so it can help improve
fuel economy.
■ Headlight control sensor (if equipped)
The sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the
windshield.
Doing so interferes with the sensor
detecting the level of ambient light and
may cause the automatic headlight sys-
tem to malfunction.
Air conditioning operation may also be
interrupted.

5-4. Refueling
Opening the fuel tank cap
●Turn the power switch off and ensure that all the doors and win -
dows are closed.
● Confirm the type of fuel.
■Fuel types
P. 725
■ Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your vehicle has a fuel tank opening that
only accommodates the special nozzle on unleaded fuel pumps.
The fuel tank of your vehicle h as a special structure, which
requires a reduction in fuel tank pressure before refueling. After
the opener switch has been pressed, it will take several second s
until the vehicle is r eady for refueling.

WARNING
■When refueling the vehicle
Observe the following precautions while refueling the vehicle. Failure to do
so may result in death or serious injury.
● After exiting the vehicle and before opening the fuel door, tou ch an
unpainted metal surface to discharge any static electricity. It is important to
discharge static electricity before refueling because sparks re sulting from
static electricity can cause fuel vapors to ignite while refuel ing.
● Always hold the grips on the fuel tank cap and turn it slowly t o remove it.
A whooshing sound may be heard when the fuel tank cap is loosen ed.
Wait until the sound cannot be heard before fully removing the cap. In hot
weather, pressurized fuel may spray out of the filler neck and cause injury.
● Do not allow anyone that has not discharged static electricity from their
body to come close to an open fuel tank.
● Do not inhale vaporized fuel.
Fuel contains substances that are harmful if inhaled.
● Do not smoke while refueling the vehicle.
Doing so may cause the fuel to ignite and cause a fire.
● Do not return to the vehicle or touch any person or object that is statically
charged.
This may cause static electricity to build up, resulting in a p ossible ignition
hazard.
■ When refueling
Observe the following precautions to prevent fuel overflowing f rom the fuel
tank:
● Securely insert the fuel nozzle into the fuel filler neck.
● Stop filling the tank after the fuel nozzle automatically click s off.
● Do not top off the fuel tank.

5-4. Refueling
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
possible, a message will be shown
on the multi-information display in
the instrument cluster to indicate
the progress of the fuel filler door
opener.
Turn the fuel tank cap slowly to
open and hang it on the back of
the fuel filler door.
NOTICE
■Refueling
● Finish refueling within 30 minutes. If more than 30 minutes passes, the
internal valve closes. In this condition, fuel may overflow dur ing the refuel-
ing process.
Press the fuel filler door opener switch again.
● Do not spill fuel during refueling.
Doing so may damage the vehicle, such as causing the emission c ontrol
system to operate abnormally or damaging fuel system components or the
vehicle’s painted surface.

■When the fuel filler door cannot be opened by pressing the insi de switch
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 du e to air being dis-
charged from inside the fuel tank. Therefore, fill the fuel tan k carefully and
slowly. Open the back door and remove the
cover underneath the luggage compart-
ment light.
Pull the lever backward and check that
the fuel lid opens.

5-5. Using the driving support systems
Normal mode
Suitable for normal driving.
When normal mode is selected, the “ECO MODE” and “PWR MODE”
indicators turn off.
Power mode
Suitable for when crisp handling and enhanced accelerator
response are desired, such as when driving on mountainous roads .
When power mode is selected, the “PWR MODE” indicator will illu mi-
nate on the main display.
Eco drive mode
Suitable for driving that impro ves fuel economy by generating
torque in response to accelerator pedal operations more smoothl y
than in normal mode.
When Eco drive mode is selected, the “ECO MODE” indicator will illumi-
nate on the main display.
While the air conditioning is being used, the system automatically
switches to air conditioning eco mode (P. 499, 510), allowing for driv-
ing that leads to even better fuel economy.
■ The driving mode after turning the power switch off
The driving mode will not be changed automatically until the switch is
pressed, even if the power switch is turned off.
