Driving
■Steering assist function/lane
centering function
●Depending on the vehicle speed,
lane departure situation, road con-
ditions, etc., the driver may not
feel the function is operating or
the function may not operate at
all.
●The steering control of the func-
tion is overridden by the driver’s
steering wheel operation.
●Do not attempt to test the opera-
tion of the steering assist function.
■Lane departure alert function
●The warning buzzer may be diffi-
cult to hear due to external noise,
audio playback, etc. Also, it may
be difficult to feel steering wheel
vibrations due to the road condi-
tions, etc.
●It may not be possi ble for the sys-
tem to determine i f there is a dan-
ger of a collision with a vehicle in
an adjacent lane.
●Do not attempt to test the opera-
tion of the lane departure alert
function.
■Hands off steering wheel warn-
ing
In the following situations, a warning
message urging the driver to hold
the steering wheel and the symbol
shown in the illustration are dis-
played on the multi-information dis-
play 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 hold-
ing 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 can-
celed. This warning also operates in
the same way when the driver con-
tinuously operates the steering
wheel only a s mall amount.
The buzzer also sounds even if the
alert type is set to .
●When the system determines that
the vehicle may deviate from the
lane while driving around a curve
while the lane centering function is
operating.
Depending on the vehicle condition
and road conditions, the warning
may not operate. Also, if the system
determines that the vehicle is driv-
ing around a curve, warnings will
occur earlier than during straight-
lane driving.
●When the system determines that
the driver is driving without hold-
ing the steering wheel while the
steering wheel assi st of the steer-
ing assist function is operating.
If the driver continues to keep their
hands off of the steering wheel and
the steering wheel assist is operat-
ing, the buzzer sounds and the
driver is warned. Each time the
buzzer sounds, the continuing time
of the buzzer becomes longer.
The buzzer also sounds even if the

Driving
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 runni ng ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle s peed is nec-
essary, 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 driver.
Approach warning warns you when the system cannot decelerate suffi-
ciently to prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you st ops, your vehicle will also stop (vehicle is
stopped by system control). Afte r the vehicle ahead starts off, pressing the
“+RES” switch or depressing the accelerator pedal (start-off operation) will
resume follow-up cruising. If the start-off operation is not pe rformed, system
control continues to keep your vehicle stopped.
When the turn signal lever is ope rated and your vehicle moves to an over-
taking lane while driving at 50 mph (80 km/h) or more, the vehi cle will accel-
erate to help to overt ake 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 versus right side driver position.) If the vehi cle is driven to a
region where the overtaking lane is on a different side from wh ere the vehi-
cle is normally driven, the vehicle may accelerate when the tur n signal lever
is operated in the opposite direction to the overtaking lane (e .g., if the driver
normally operates the vehicle in a region where the overtaking lane is to the
right but then drives to a region where the overtaking lane is to the left, the

●When the vehicle is towing a
trailer or during emergency tow-
ing.
●When the vehicle is lifted up,
except in the following cases.
• When using a Toyota official lift kit up to 4 in. (101 mm), including tire
height. Aftermarket lift kits may

■Conditions under which the
vehicle-to-vehicle distance con-
trol mode may not function cor-
rectly
In the case of the following condi-
tions, operate the brake pedal (or
accelerator pedal, depending on the
situation) as necessary.
As the sensor may not be able to
correctly detect vehicles ahead, the

your position in t he lane is unsta-
ble
●When the vehicle ahead of you
decelerates suddenly
