In the following situations, if the situation has changed (or the vehicle has
been driven for some time) and the normal operating conditions are
detected, the message will disappear and the system will become opera-
tional.
If the message does not disappear, contact your Toyota dealer.
• When the temperature around the radar sensor is outside of the opera- tional range, such as when the vehicle is in the sun or in an e xtremely
cold environment
• When the front camera cannot detect objects in front of the ve hicle, such
as when driving in the dark, snow, or fog, or when bright lights are shining
into the front camera

• When the surrounding area is dim, such as at dawn or dusk, or
while at
night or in a tunnel, making a detectable object appear to be n early the
same color as its surroundings
• When driving in a place where the surrounding brightness changes sud- denly, such as at the entrance or exit of a tunnel
• After the fuel cell system has started the vehicle has not bee n driven for a
certain amount of time
• While making a left/right turn and for a few seconds after mak ing a left/
right turn
• While driving on a curve and for a few seconds after driving o n a curve
• If your vehicle is skidding
• If the wheels are misaligned
• If a wiper blade is blocking the front camera
• The vehicle is being driven at extremely high speeds
• When driving on a hill
• If the radar sensor or front camera is misaligned
● In some situations such as the following, sufficient braking fo rce may not be
obtained, preventing the system from performing properly:
• If the braking functions cannot operate to their full extent, such as when
the brake parts are extremely cold, extremely hot, or wet
• If the vehicle is not properly maintained (brakes or tires are excessively
worn, improper tire inflation pressure, etc.)
• When the vehicle is being driven on a gravel road or other sli ppery sur-
face
■ If VSC is disabled
●If VSC is disabled ( P. 297), the pre-collision brake assist and pre-collision
braking functions are also disabled.

When the system determines that t he driver is driving without holding the
steering wheel while the steering wheel assist of the steering assist function
is operating.
If the driver continues to keep their hands off of the steering wheel and the
steering wheel assist is operating, the buzzer sounds and the d river is
warned. Each time the buzzer sounds, the continuing time of the buzzer
becomes longer.
■ Vehicle sway warning function
■ Warning message
If the following warning message is displayed on the multi-info rmation display
and the LDA indicator illuminates in yellow, follow the appropr iate trouble-
shooting procedure. Also, if a different warning message is displayed, follow
the instructions displayed on the screen.
● “Lane Departure Alert Malfunction Visit Your Dealer”
The system may not be operating properly. Have the vehicle insp ected by
your Toyota dealer.
● “Lane Departure Alert Unavailable”
The system is temporarily canceled due to a malfunction in a se nsor other
than the front camera. Turn the LDA system off, wait for a little while, and
then turn the LDA system back on.
● ”Lane Departure Alert Unav ailable at Current Speed”
The function cannot be used as the vehicle speed exceeds the LD A opera-
tion range. Drive slower.
● “Lane Departure Alert Unavai lable Below Approx 32MPH”
The LDA system cannot be used as the vehicle speed is less than approxi-
mately 32 mph (50 km/h). Drive the vehicle at approximately 32 mph
(50 km/h) or more.
■ Customization
Function settings can be changed.
(Customizable features: P. 484)
When the system determines that the
vehicle is swaying while the vehicle sway
warning function is operating, a buzzer
sounds and a warning message urging
the driver to rest and the symbol shown in

This mode employs a radar to detect the presence of vehicles up to
approximately 328 ft. (100 m) ahead, determines the current veh icle-
to-vehicle following distance, and operates to maintain a suita ble fol-
lowing distance from the vehicle ahead. The desired vehicle-to- vehi-
cle distance can also be set by operating the vehicle-to-vehicl e
distance switch.
When driving on downhill slopes, the vehicle-to-vehicle distance may
become shorter.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver.
Example of deceleration crui sing and follow-up cruising
When a preceding vehicle driving slower than the set speed
appears
When a vehicle is detected running ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle s peed is
necessary, the system applies the brakes (the stop lights will come on at
this time).
The system will respond to changes in the speed of the vehicle ahead in
order to maintain the vehicle-to-vehicle distance set by the dr iver.
Approach warning warns you when the system cannot decelerate su ffi-
ciently to prevent your vehicle fr om closing in on the vehicle ahead.
When the turn signal lever is operated and your vehicle moves to a left
lane while driving at 50 mph (80 km/h) or more, the vehicle wil l quickly
accelerate to help to overtake a passing vehicle.

increased or decreased as follows:
For U.S.A.
Fine adjustment: By 1 mph (1.6 km/h)
*1 or 1 km/h (0.6 mph)*2 each time
the lever is operated
Large adjustment: Increases or decreases in 1 mph (1.6 km/h)
*1 or 1 km/h
(0.6 mph)
*2 increments for as long as the lever is held
For Canada
Fine adjustment: By 1 mph (1.6 km/h)

(3.1 mph)
*2 increments for as long as the lever is held
In the constant speed control mode ( P. 257), the set speed will be
increased or decreased as follows:
Fine adjustment: By 1 mph (1.6 km/h)*1 or 1 km/h (0.6 mph)*2 each time
the lever is operated
Large adjustment: The speed will continue to change while the l ever is
held.

■Dynamic radar cruise control can be set when
●The shift position is in D.
● Depending on the control mode, this item can be set at the foll owing
speeds.
• Vehicle-to-vehicle distance c ontrol mode: Approximately 20 mph (30 km/h)
or more
• Constant speed control mode: Approximately 20 mph (30 km/h) or more
■ Accelerating after setting the vehicle speed
The vehicle can accelerate by operating the accelerator pedal. After acceler-
ating, the set speed resumes. However, during vehicle-to-vehicl e distance
control mode, the vehicle speed may decrease below the set spee d in order
to maintain the distance to the preceding vehicle.
■ Automatic cancelation of vehicle-to-vehicle distance control mode
Vehicle-to-vehicle distance control mode is automatically cance led in the fol-
lowing situations.
● Actual vehicle speed falls below approximately 16 mph (25 km/h) .
● VSC is activated.
● TRAC is activated for a period of time.
● When the VSC or TRAC system is turned off.
● The sensor cannot detect correctly because it is covered in some way.
● Pre-collision braking is activated.
If vehicle-to-vehicle distance control mode is automatically ca nceled for any
reasons other than the above, there may be a malfunction in the system.
Contact your Toyota dealer.
■ Automatic cancelation of c onstant speed control mode
Constant speed control mode is automatically canceled in the following situa-
tions:
● Actual vehicle speed is more than approximately 10 mph (16 km/h ) below
the set vehicle speed.
● Actual vehicle speed falls below approximately 20 mph (30 km/h) .
● VSC is activated.
● TRAC is activated for a period of time.
● When the VSC or TRAC system is turned off.
● Pre-collision braking is activated.
If constant speed control mode is automatically canceled for any reasons
other than the above, there may be a malfunction in the system. Contact your
Toyota dealer.
■ Brake operation
A brake operation sound may be heard and the brake pedal response may
change, but these are not malfunctions.

■Adjusting the temperature setting
To adjust the temperature set-
ting, touch and slide your finger
up or down on the sensor.
The temperature setting can
also be adjusted by touching on
the sensor.
When the temperature setting is
changed, a buzzer sounds.
If the indicator is turned
off, the system will blow ambient
temperature air or heated air.
The temperature for the driver’s and front passenger’s can be
adjusted separately when:
• The front passenger’s side tem perature setting is touched.
• The air conditioning system switches between individual and synchronized modes each time is touched.
Air outlets and fan speed are automatically adjusted according
to the temperature setting.
