■Fuel types
 P.592
■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.
Opening the fuel tank
cap
Perform the following steps to
open the fuel tank cap:
Before refueling the vehicle
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 surface to dis-
charge any static electricity. It is important to discharge static elec-tricity before refueling because
sparks resulting from static electric- ity 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 fuel 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 stati-
cally charged. This may cause static electricity to build up, result-ing in a possible ignition hazard.
■When refueling
Observe the following precautions to
prevent fuel overflowing from the fuel tank:
●Securely insert the fuel nozzle into
the fuel filler neck.
●Stop filling the tank after the fuel
nozzle automatically clicks off.
●Do not top off the fuel tank.
NOTICE
■Refueling
Do not spill fuel during refueling. Doing so may damage the vehicle,
such as causing the emission control system to operate abnormally or dam-aging fuel system components or the
vehicle’s painted surface.

Driving
■Conditions under which the system
may not function correctly
●The BSM function may not detect
vehicles correctly in the following situ-
ations:
• When the sensor is misaligned due to
a strong impact to the sensor or its
surrounding area
• When mud, snow, ice, a sticker, etc.,
is covering the sensor or surrounding
area on the rear bumper
• When driving on a road surface that is
wet with standing water during bad
weather, such as heavy rain, snow, or
fog
• When multiple vehicles are approach-
ing with only a small gap between
each vehicle
• When the distance between your vehi-
cle and a following vehicle is short
• When there is a significant difference
in speed between your vehicle and
the vehicle that enters the detection
area
• When the difference in speed
between your vehicle and another
vehicle is changing
• When a vehicle enters a detection
area traveling at about the same
speed as your vehicle
• As your vehicle starts from a stop, a
vehicle remains in the detection area
• When driving up and down consecu-
tive steep inclines, such as hills, dips
in the road, etc.
• When driving on roads with sharp
bends, consecutive curves, or uneven
surfaces
• When vehicle lanes are wide, or when
driving on the edge of a lane, and the
vehicle in an adjacent lane is far away
from your vehicle
• When an accessory (such as a bicycle
carrier) is installed to the rear of the
vehicle
• When there is a significant difference
in height between your vehicle and
the vehicle that enters the detection
area
• Immediately after the BSM func-
tion/RCTA function are turned on
• When towing a trailer
●Instances of the BSM function unnec-
essarily detecting a vehicle and/or
object may increase in the following
situations:
• When the sensor is misaligned due to
a strong impact to the sensor or its
surrounding area
• When the distance between your vehi-
cle and a guardrail, wall, etc. that
enters the detection area is short
• When driving up and down consecu-
tive steep inclines, such as hills, dips
in the road, etc.
• When vehicle lanes are narrow, or
when driving on the edge of a lane,
and a vehicle traveling in a lane other
than the adjacent lanes enters the
detection area
• When driving on roads with sharp
bends, consecutive curves, or uneven
surfaces
• When the tires are slipping or spinning
• When the distance between your vehi-
cle and a following vehicle is short
• When an accessory (such as a bicycle
carrier) is installed to the rear of the
vehicle
• When the vehicle throws up water or
snow behind.
■Operation of the RCTA func-
tion
The RCTA function uses radar sen-
sors to detect vehicles approaching
from the right or left at the rear of
the vehicle and alerts the driver of
the presence of such vehicles by
flashing the outside rear view mirror
indicators and sounding a buzzer.

6-1. Using the air conditioning system and defogger
Interior features
●The outside temperature is extremely
low
●When the hybrid system is cool (for
example, after being left for a long time in low temperatures)
■Windshield defogger
When defogging the windshield using
the Remote Air Conditioning System, defogging may be insufficient due to the power being restricted more than during
normal air conditioning operation. Also, the outside of the windshield may fog up due to the outside temperature, humidity
or air conditioning set temperature.
■Using the heater via the Remote Air Conditioning System
●When the outside temperature is low, heating may feel insufficient due to restricted operation of the air condi-
tioning.
●When the outside heat exchanger
becomes frosted over, heating perfor- mance may decline due to automati-cally switching to the frost removal
operation. ( P.432)
■Security feature
Any unlocked doors will be automatically locked when the system is operating.
The emergency flashers flash to indicate that the doors have been locked or the system has been turned off.
■Conditions affecting operation
 P.254
■While the Remote Air Conditioning System is operating
●Depending on the operating condition of the Remote Air Conditioning Sys-tem, the air conditioning compressor
or cooling fan may spin and an operat- ing noise may be heard.However, this does not indicate a mal-
function.
●The air conditioning operation
switches, etc. will not operate while the Remote Air Conditioning System is operating.
■Electronic key battery depletion
 P.232
■When the electronic key battery is fully depleted
 P.511
■Customization
Setting (e.g. Operation using “A/C” on the wireless remote control) can be changed. (Customizable features:
 P.607)
WARNING
■Precautions for the Remote Air Conditioning System
●Do not use the system if people are in the vehicle. Even when the system is in use, the
internal temperature may still reach a high or low level due to features such as the automatic shut-off.
Children and pets left inside the vehicle may suffer heatstroke dehy-dration or hypothermia, or could
result in death or serious injury.
●Depending on the surrounding envi-
ronment, signals from the wireless switch may transmit further than expected. Pay appropriate attention
to the vehicle’s surroundings and use the switch only when neces-sary.
●Do not operate “A/C” on the wire-less remote control if the hood is
open. The air conditioning may operate unintentionally and objects may be drawn into the electrical
cooling fan.
NOTICE
■To prevent the hybrid battery (traction battery) from being dis-charged
Use “A/C” on the wireless remote control only when necessary.
