detection function, preventing the func-
tion from operating properly:
• Pedestrians who are bending forward or squatting
• Pedestrians who are lying down
• Pedestrians who are running
• Pedestrians who suddenly enter the detection area
• People riding a bicycle, skateboard, or other light vehicle
• Pedestrians wearing oversized clothing such as a rain coat, long skirt, etc., making
their silhouette obscure
• Pedestrians whose body is partially hid- den by an object, such as a cart or
umbrella
• Pedestrians which are obscured by dark- ness, such as at night
●In some situations, such as the following,
pedestrians may not be detected by the
rear camera detection function, prevent-
ing the function from operating properly:
• When backing up in inclement weather (rain, snow, fog, etc.)
• When the rear camera is obscured (dirt,
snow, ice, etc. are attached) or scratched
• When a very bright light, such as the sun, or the headlights of another vehicle,
shines directly into the rear camera
• When backing up in a place where the surrounding brightness changes sud-
denly, such as at the entrance or exit of a
garage or underground parking lot
• When backing up in a dim environment
such as during dusk or in an underground
parking lot
●Even though there are no pedestrians in
the detection area, some objects, such as
the following, may be detected, possibly
causing the rear camera detection func-
tion to operate.
• Three dimensional objects, such as a
pole, traffic cone, fence, or parked vehi-
cle
• Moving objects, such as a car or motor-
cycle
• Objects moving toward your vehicle when backing up, such as flags or pud-
dles (or airborne matter, such as smoke,
steam, rain, or snow)
• Cobblestone or gravel roads, tram rails,
road repairs, white lines, pedestrian
crossings or fallen leaves on the road • Metal covers (gratings), such as those
used for drainage ditches
• Objects reflected in a puddle or on a wet road surface
• The roadside or bumps on the road
•Shadows on the road
●In some situations, such as the following,
the rear camera detection function may
operate even though there are no pedes-
trians in the detection area.
• When backing up toward the roadside or a bump on the road
• If the vehicle is signif icantly tilted, such as
when carrying a heavy load
• When backing up toward an
incline/decline
• If the suspension has been modified or tires of a size othe r than specified are
installed
• If the rear of the vehicle is raised or low- ered due to the carried load
• If an electronic component, such as a
backlit license plate is installed near the
rear camera
• If a bumper protector, such as an addi-
tional trim strip, is installed to the rear
bumper
• If the orientation of the rear camera has
been changed due to a collision or other
impact, or removal and installation
• If a towing eyelet is in stalled to the rear of
the vehicle
• When water is flowing over the rear cam- era lens
• When the rear camera is obscured (dirt,
snow, ice, etc. are at tached) or scratched
• If there is a flashing light in the detection
area, such as the emergency flashers of
another vehicle
●Situations in which the rear camera
detection function may be difficult to
notice
• The buzzer may be difficult to hear if the surrounding area is noisy, the volume of
the audio system volume is high, the air
conditioning system is being used, etc.
• If the temperature in the cabin is extremely high or low, the Center Display
may not operate correctly.

4-6.Driving tips
When using Eco drive mode, the
torque corresponding to the accelera-
tor pedal depression amount can be
generated more smoothly than it is in
normal conditions. In addition, the
operation of the air conditioning sys-
tem (heating/cooling) will be mini-
mized, improving the fuel economy.
( P.212)
The Eco-friendly driving is possible by
keeping the indicate of Hybrid System
Indicator within Eco area. ( P.77)
Shift the shift lever to D when stopped
at a traffic light, or driving in heavy traf-
fic etc. Shift the shift lever to P when
parking. When using the N, there is no
positive effect on fuel consumption. In
the N, the gasoline engine operates
but electricity cannot be generated.
Also, when using the air conditioning
system, etc., the hybrid battery (trac-
tion battery) power is consumed. 
Drive your vehicle smoothly. Avoid
abrupt acceleration and decelera-
tion. Gradual acceleration and
deceleration will make more effec-
tive use of the electric motor (trac-
tion motor) without having to use
gasoline engine power.
 Avoid repeated acceleration.
Repeated acceleration consumes
hybrid battery (traction battery)
power, resulting in poor fuel con-
sumption. Battery power can be
restored by driving with the acceler-
ator pedal slightly released.
Make sure to operate the brakes gently
and in a timely manner. A greater
amount of electrical energy can be
regenerated when slowing down.
Repeated acceleration and decelera-
tion, as well as long waits at traffic
lights, will lead to bad fuel economy.
Check traffic reports before leaving
and avoid delays as much as possible.
When driving in a traffic jam, gently
release the brake pedal to allow the
vehicle to move forward slightly while
avoiding overuse of the accelerator
pedal. Doing so can help control
excessive gasoline consumption.
Hybrid vehicle driving tips
For economical and ecological
driving, pay attention to the follow-
ing points:
Using Eco drive mode
Use of Hybrid System Indicator
Shift lever operation
Accelerator pedal/brake pedal
operation
When braking
Delays

2524-6. Driving tips
Control and maintain the vehicle at a
constant speed. 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
regenerated when slowing down.
Use the air conditioning only when
necessary. Doing so can help reduce
excessive gasoline consumption.
In summer: When the ambient tem-
perature is high, use the recirculated
air mode. Doing so will help to reduce
the burden on the air conditioning sys-
tem and reduce fuel consumption as
well.
In winter: Because the gasoline engine
will not automatically cut out until it and
the interior of the vehicle are warm, it
will consume fuel. Also, fuel consump-
tion can be improved by avoiding over-
use of the heater.
Make sure to check the tire inflation
pressure frequently. Improper tire infla-
tion pressure can cause poor fuel
economy.
Also, as snow tires can cause large
amounts of friction, their use on dry
roads can lead to poor fuel economy.
Use tires that are appropriate for the
season. Carrying heavy luggage will lead to
poor fuel economy. Avoid carrying
unnecessary luggage.
Installing a large
roof rack will also cause poor fuel
economy.
Since the gasoline engine starts up and
cuts out automatically when cold,
warming up the engine is unnecessary.
Moreover, frequently driving short dis-
tances will cause the engine to repeat-
edly warm up, which can lead to excess
fuel consumption.

■Defogging the windshield
Defoggers are used to defog the wind-
shield and front side windows.
Press the windshield defogger switch.
Set the outside/reci rculated air mode
switch to outside air mode if the recircu-
lated air mode is used. (It may switch auto-
matically.)
To defog the windshield and the side win-
dows early, turn the air flow and tempera-
ture up.
To return to the previous mode, press the
windshield defogger switch again when the
windshield is defogged.
■Defogging the rear window and
outside rear view mirrors
Defoggers are used to defog the rear
window, and to remove raindrops, dew
and frost from the outside rear view
mirrors.
Press the rear window and outside rear
view mirror defoggers switch.
The defoggers will automatically turn off
after 15 minutes.
■When the outside temperature exceeds
75°F (24°C) and the air conditioning
system is on
●In order to reduce the air conditioning
power consumption, the air conditioning
system may switch to recirculated air
mode automatically. This may also
reduce fuel consumption.
●Recirculated air mode is selected as a
default mode when the power switch is
turned to ON mode.
●It is possible to switch to outside air mode
at any time by pressing the outside/recir-
culated air mode switch.
■Fogging up of the windows
The windows will easily fog up when the
humidity in the vehicle is high. Turning “A/C”
on will dehumidify the air from the outlets
and defog the windshield effectively.
●If you turn “A/C” off, the windows may fog
up more easily.
●The windows may fog up if the recircu-
lated air mode is used.
■When driving on dusty roads
Close all windows. If dust thrown up by the
vehicle is still drawn into the vehicle after
closing the windows, it is recommended
that the air intake mode be set to outside air
mode and the fan speed to any setting
except off.
■Outside/recirculated air mode
●Setting to the recirculated air mode tem-
porarily is recommended in preventing
