821-4. Hybrid system
*: This function can only be used in
the mainland U.S.A. It cannot be
used in other states and territo-
ries, including Alaska and Hawaii.
This system operates based on
the driving situation and traffic
information to enhance fuel
economy.
For details about Predictive effi-
cient drive, refer to “NAVIGA-
TION AND MULTIMEDIA
SYSTEM OWNER’S MANUAL”.
■Predictive deceleration sup-
port
 When the vehicle approaches
to predictive deceleration sup-
port points registered in the
navigation system, the “Refer-
ence operation range” ( ) of
the ECO Accelerator Guid-
ance ( P.108) on the multi-
information display will be
turned off to encourage the
driver to reduce excessive
acceleration.
 The engine braking force will be increased according to the
driving conditions to more effi-
ciently charge the hybrid bat-
tery (traction battery) after the
accelerator pedal is released.
■Predictive SOC control
The following types of control
are performed based on data
such as road and traffic informa-
tion during route guidance by
the navigation system to help
ensure that the vehicle effi-
ciently uses electricity.
 When there is a long downhill
slope along the route, the sys-
tem reduces the hybrid bat-
tery (traction battery) level
before reaching the slope to
help ensure charging capacity
for regenerative braking while
traveling downhill.
 When traffic congestion is
predicted along the route, the
system helps ensure a certain
battery level before reaching
congested roads to reduce
the frequency of starting the
engine to charge the hybrid
battery (traction battery) due
to low battery levels.

■AUTO mode can be used when
The power switch is in ON.
■Daytime running light system
●Vehicles without projector head-
lights (type A): The daytime run-
ning lights illuminate using the
same lights as the low beam
headlights and illu minate dimmer
than the low beam headlights.
●Vehicles without projector head-
lights (type B): The daytime run-
ning lights illuminate using the
same lights as the parking lights
and illuminate brighter than the
parking lights.
●Vehicles with projector headlights:
The daytime runn ing lights illumi-
nate using the same lights as the
parking lights and illuminate
brighter than the parking lights.
●To make your vehicle more visible
to other drivers during daytime
driving, the daytime running lights
turn on automatically when all of
the following conditions are met.
(The daytime running lights are
not designed for use at night.)
• The hybrid system is operating
• The parking brake is released
• The headlight switch is in the
or
* position
• The fog lights are not illuminated
*: When the surroundings are bright
The daytime running lights remain
on after they illumi nate, even if the
parking brake is set again.
●For the U.S.A.: Daytime running
lights can be turned off by operat-
ing the switch.
●Compared to turning on the head-
lights, the daytime running light
system offers greater durability
and consumes less electricity, so
it can help improve fuel economy.

 Confirm the type of fuel.
■Fuel types
 P.528
■Fuel tank opening for unleaded
gasoline
To help prevent incorrect fueling,
your vehicle has a fuel tank opening
that only accommodates the spe-
cial nozzle on unle aded fuel pumps.
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 several seconds
until the vehicle is ready 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,
touch an unpainted metal sur-
face to discharge any static
electricity. It is important to dis-
charge static electricity before
refueling because sparks result-
ing from static electricity can
cause fuel vapors to ignite while
refueling.
●Always hold the grips on the
fuel tank cap and turn it slowly
to remove it.
A whooshing sound may be
heard when the f uel tank cap is
loosened. 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 possible igni-
tion hazard.

Interior features
switch.
■Operation of the air condition-
ing system in Eco drive mode
●In Eco drive mode, the air condi-
tioning system is controlled as fol-
lows to prioritize fuel efficiency:
• Engine speed and compressor operation controlled to restrict
heating/cooling capacity
• Fan speed restr icted when auto-
matic mode is selected
●To improve air conditioning perfor-
mance, perform the following
operations:
• Adjust the fan speed
• Turn off Eco drive mode ( P.333)
• Turn off Eco air conditioning mode
●When the driving mode is set to
Eco driving mode, the Eco air con-
ditioning mode will be turned on
automatically. Even in this case,
the Eco air conditioning mode can
be turned off by pressing the Eco
air conditioning mode switch.
■When the outside temperature
falls to nearly 32°F (0°C)
The dehumidification function may
not operate even when “A/C” switch
is pressed.
■Ventilation and air conditioning
odors
●To let fresh air in, set the air condi-
tioning system to the outside air
mode.
●During use, various odors from
inside and outside the vehicle may
enter into and a ccumulate 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 out-
side 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 con-
ditioning system is started in auto- matic mode.
●When parking, the system auto-
matically switches to outside air
mode to encourage better air cir-
culation throughout the vehicle,
helping to reduce odors that occur
when starting the vehicle.
