NOTICE
■
When encountering flooded roads
Do not drive on a road that has flooded after heavy rain etc. Doing so may
cause the following serious damage to the vehicle:
● Engine stalling
● Short in electrical components
● Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be
sure to have your Toyota dealer check the following:
● Brake function
● Changes in quantity and quality of engine oil, transmission fluid for the
hybrid system, etc.
● Lubricant condition for the bearings and suspension joints (where possi-
ble), and the function of all joints, bearings, etc.
If the P position control system is damaged by flooding, it may not be possi-
ble to shift the shift position to P, or from P to other positions. When the shift
position cannot be changed from P to any other position, the front wheels
will lock, and you will be unable to tow the vehicle with the front wheels on
the ground, as the front wheels may be locked. In this case, transport the
vehicle with both front wheels or all four wheels lifted.

CAUTION
■When the sensor may not be corr ectly detecting the vehicle ahead
Apply the brakes as necessary when any of the following types of vehicles
are in front of you.
As the sensor may not be able to correctly detect these types of vehicles,
the approach warning ( P. 279) will not be activated, and a fatal or serious
accident may result.
● Vehicles that cut in suddenly
● Vehicles traveling at low speeds
● Vehicles that are not moving
● Vehicles with small rear ends (trailers with no load on board etc.)
● Motorcycles traveling in the same lane
■ Conditions under which the vehicle -to-vehicle distance control may
not function correctly
Apply the brakes as necessary in the following conditions as the radar sen-
sor may not be able to correctly detect vehicles ahead, and a fatal or serious
accident may result:
● When water or snow thrown up by the surrounding vehicles hinders the
functioning of the sensor
● When your vehicle is pointing upwards (caused by a heavy load in the lug-
gage compartment etc.)
● When the road curves or when the lanes are narrow
● When steering wheel operation or your position in the lane is unstable
● When the vehicle ahead of you decelerates suddenly

warning
* given via the steering wheel.

control mode of the cruise control ( P. 272) is set with vehicle
speed above approximately 45 mph (72 km/h) and while the
lane departure warning function is active.
• When the lane keeping assist function is active, a slight steering torque will be applied, to help the driver maintain the vehicle
inside the lane.
The lane keeping assist function will be temporarily canceled if the steer-
ing wheel is not operated, or if you continue driving with your hands

■No-handed driving warning
If the steering wheel is not operated for approximately 15 seconds on a
straight road or approximately 5 seconds on a curve, the buzzer will beep
twice, indicators on the multi-information display will flash, and the lane
keeping assist function will be temporarily canceled. If you drive the vehicle
with your hands lightly touching the steering wheel, this may also be
detected as no-handed driving.
■ After the vehicle has been parked in the sun
The LKA system functions may not be available and a warning message
(P. 520) will be displayed for a while after driving has started. In such
cases, turn the LKA system off and turn it on again after normal temperature
returns. When the temperature in the cabin decreases and the temperature
around the camera sensor ( P. 289) becomes suitable for its operation, the
functions will begin to operate.
■ If there are lane markers on only one side of the vehicle
The lane keeping assist function will not operate. Also, the lane departure
warning will not operate for the side on which lane markers could not be rec-
ognized.
■ Conditions in which the function may not operate correctly
In the following conditions, the LKA system functions may not operate, or it
may not be possible to ensure adequate performance. Also, the camera
sensor may be unable to recognize lane lines causing the lane departure
warning function to operate incorrectly, or the lane keeping assist function
may not operate properly. However, this does not indicate a malfunction.
● When driving through an area with no lane markers, such as a tollbooth,
a crossing or before a ticket checkpoint
● When driving on a sharp curve
● When lanes are extremely narrow or extremely wide
● When the vehicle leans to one side an unusual amount due to a heavy
load or improper tire inflation pressure
● When the following distance between your vehicle and the vehicle ahead
is extremely short
