When driving
■Rain drop sensor
■If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the wind-
shield washer fluid reservoir.
■In extremely hot or cold weather
The system will turn off if the windshield gets extremely hot (at more than 176 F
[80 C]) or cold (at less than 14 F [-10C]).
■Customization
Settings (e.g. drip prevention function) can be changed. ( P. 500)
CAUTION
■Caution regarding the use of windshield wipers in “AUTO” mode
The windshield wipers may operate unexpectedly if the sensor is touched or the
windshield is subject to vibration in “AUT O” mode. Take care that your fingers or
anything else do not become caught in the windshield wipers.
NOTICE
■When the windshield is dry
Do not use the wipers, as they may damage the windshield.

When driving
●In the following situations, the intuitive parking assist may not function correctly,
possibly leading to an accident.
• There is ice, snow or mud on the sensors. (Wiping the sensors will resolve this problem.)
• The sensor area is frozen. (Thawing the area will resolve this problem.) 
In especially cold weather, if a sensor is frozen the screen may show an abnor-
mal display, or obstacles may not be detected.
• The vehicle angle is especially wide.
• In harsh sunlight or intense cold weather.
• When driving on bumpy, sloped or gravel roads, or over grass.
• If there is something producing ultrasonic waves nearby, such as another vehicle’s horn, motorcycle engine nois e, air braking sound from heavy-duty
vehicles, or another vehicle using the intuitive parking assist.
• In heavy rain, or if water is splashed on the sensors.
• If a commercial fender pole or radio antenna is installed.
• If towing eyelet is installed on your vehicle.
• If moving towards a high curb or a curb corner.
• Objects such as signs may cause the detection distance to shorten.
• The area directly under the bumpers is not detected. 
Objects lower than the sensor s or thin stakes etc. may be detected initially,
but as they draw closer, they may cease to be detected.
• If obstacles draw too close to the sensor.
■Obstacles that may not be detected correctly
The following obstacles may not be detected.
• Thin objects such as wire, fencing or rope.
• Objects that absorb sound waves, such as cotton or snow.
• Objects with sharp corners.
• Objects where the upper section projects out over the lower section.
•Low objects.

2-5. Driving information
Cargo and luggage
Capacity and distribution
Cargo capacity depends on the total weight of the occupants.
(Cargo capacity) = (Total load capa city) — (T
otal weight of occupants)
Steps for Determining Correct Load Limit—
(1) Locate the statement “The combined weight of occupants and car
go should never exceed XXX kg or XXX lbs.” on your vehicle’s
placard.
(2) Determine the combined weight of the driv
er and passengers that
will be riding in your vehicle.
(3) Subtract the combined weight of the driv
er and passengers from
XXX kg or XXX lbs.
(4) The resulting figure equals the av ailable amount of car
go and lug-
gage load capacity.
For example, if the “XXX” amount equals 1400 lbs. and ther
e will be
five 150 lb passengers in your vehicl e, the amount of available cargo
and luggage load capacity is 650 lbs. (1400 - 750 (5 150) = 650
lbs.)
(5) Determine the combined weight of luggage and car
go being
loaded on the vehicle.
That weight may not safely exceed the available cargo and luggage
load capacity calculated in Step 4.
Take notice of the following informat ion about storage precautions, cargo
capacity and load.
● Stow cargo and luggage in the trunk whenever possible. Be sure
all items are secured in place.
● Be car
eful to keep the vehicle level. Placing the weight as far for-
ward as possible helps maintain vehicle balance.
● F
or better fuel economy, do not carry unnecessary weight.
