radar cruise control and provides
the required assistance by operat-
ing the steering wheel to keep the
vehicle in its current lane.
When dynamic radar cruise control is
not operating, the lane centering func-
tion does not operate.
In situations where the white (yellow)
lane lines are difficult to see or are not
visible, such as when in a traffic jam,
this function will operate to help follow a
preceding vehicle by monitoring the
position of the preceding vehicle.
■Changing the lane centering
function ON/OFF condition
The lane centering function turns
ON/OFF each time the LTA switch
is pressed.
The LTA settings state is displayed on
the multi-information display when the
LTA switch is pressed.

■Hands off steering wheel warning
In the following situations, a warning
message urging the driver to hold the
steering wheel and the symbol shown in
the illustration are displayed on the
multi-information display to warn the
driver. The warning stops when the sys-
tem determines that the driver holds the
steering wheel. Always keep your hands
on the steering wheel when using this
system, regardless of warnings.
●When the system determines that the
driver is driving without holding the
steering wheel while the system is
operating
If the driver continues to keep their
hands off of the steering wheel, the
buzzer sounds, the driver is warned and
the function is temporarily canceled.
This warning also operates in the same
way when the driver continuously oper-
ates the steering wheel only a small
amount.
The buzzer also sounds even if the alert
type is set to steering wheel vibration.
●When the system determines that the
vehicle may not turn and instead
depart from its lane on a curve while
the lane centering function is operat-
ing.
Depending on the vehicle condition and
road conditions, the warning may not
operate. Also, if the system determines
that the vehicle is driving around a
curve, warnings will occur earlier than
during straight-lane driving.
●When the system determines that the
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 driver is warned.
Each time the buzzer sounds, the con-
tinuing time of the buzzer becomes lon-
ger.
The buzzer also sounds even if the alert
type is set to steering wheel vibration.
■Vehicle sway warning function
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 the illustration are simultane-
ously displayed on the multi-information
display.
Depending on the vehicle and road con-
ditions, the warning may not operate.
■Warning message
If the following warning message is dis-
played on the multi-information display
and the LTA indicator illuminates in
orange, follow the appropriate trouble-
shooting procedure. Also, if a different
warning message is displayed, follow
the instructions displayed on the screen.

4-5. Using the driving support systems
This mode employs a radar to detect the presence of vehicles up to approx-
imately 100 m (328 ft.) ahead, determines the current vehicle-to-vehicle fol-
lowing distance, and operates to maintain a suitable following distance from
the vehicle ahead. The desired vehicle-to-vehicle distance can also be set
by operating the vehicle-to-vehicle 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 cruising 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 deceler-
ates your vehicle. When a greater reduction in vehicle speed is necessary, the sys-
tem 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 vehi-
cle-to-vehicle distance set by the driver. Approach warning warns you when the sys-
tem cannot decelerate sufficiently to prevent your vehicle from closing in on the
vehicle ahead.
When the turn signal lever is operated and your vehicle moves to an overtaking lane
while driving at 80 km/h (50 mph) or more, the vehicle will accelerate to help to over-
take a passing vehicle.
The system’s identification of what is an overtaking lane may be determined solely
based on the location of the steering wheel in the vehicle (left side driver position

●Motorcycles traveling in the same lane
●When water or snow thrown up by the
surrounding vehicles hinders the
detecting of the sensor
●When your vehicle is pointing
upwards (caused by a heavy load in
the luggage compartment, etc.)
●Preceding vehicle has an extremely
high ground clearance
■Conditions under which the vehi-
cle-to-vehicle distance control
mode may not function correctly
In the case of the following conditions,
operate the brake pedal (or accelerator
pedal, depending on the situation) as
necessary.
As the sensor may not be able to cor-
rectly detect vehicles ahead, the system
may not operate properly.
●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 decel-
erates suddenly
●When driving on a road surrounded by
a structure, such as in a tunnel or on a
bridge
●While the vehicle speed is decreasing

accelerates by depressing the accel-
erator pedal

before the engine is restarted and
drive force is generated. When
drive force is generated, the main-
tained brake force is automatically
canceled.
zThis function operates on flat
surfaces as well as steep
inclines.
zSound may be generated from
the brake system, but this does
not indicate a malfunction.
zBrake pedal response may
change and vibration may occur,
but this does not indicate a mal-
function.
■Points for use
●If the engine switch is pressed when
the engine is stopped by the Stop &
Start system, the engine will not be

engine starting procedure. (→ P.158,
159)
●When the engine is being restarted by
the Stop & Start system, the power
outlets may be temporarily unusable,
but this does not indicate a malfunc-
tion.
●Installation and removal of electrical
components and wireless devices
may affect the Stop & Start system.
Contact any authorized Toyota retailer
or Toyota authorized repairer, or any
reliable repairer for details.
●When stopping the vehicle for a lon-
ger period of time, turn the engine
switch off to stop the engine com-
pletely.
