■Lane departure alert function
When the system determines that
the vehicle might depart from its
lane or course*, a warning is dis-
played on the multi-information dis-
play, and a warning buzzer will
sound to alert the driver.
When the warning buzzer sounds,
check the area around your vehicle and
carefully operate the steering wheel to
move the vehicle back to the center of
the lane.
Vehicle with BSM: When the system
determines that the vehicle might
depart from its lane and that the possi-
bility of a collision with an overtaking
vehicle in the adjacent lane is high, the
lane departure alert will operate even if
the turn signals are operating.

side of the road, such as grass, soil,
or a curb
■Steering assist function
When the system determines that
the vehicle might depart from its
lane or course*, the system pro-
vides assistance as necessary by
operating the steering wheel in
small amounts for a short period of
time to keep the vehicle in its lane.

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

Fine adjustment: Press the switch.
Large adjustment: Press and hold the
switch to change the speed, and
release when the desired speed is
reached.
In the vehicle-to-vehicle distance
control mode, the set speed will be
increased or decreased as follows:
Fine adjustment: By 1 km/h (0.6 mph)*1
or 1 mph (1.6 km/h)*2 each time the
switch is pressed
Large adjustment: Increases or
decreases in 5 km/h (3.1 mph)*1 or 5
mph (8 km/h)*2 increments for as long
as the switch is held
In the constant speed control mode
( →P.188), the set speed will be
increased or decreased as follows:
Fine adjustment: By 1 km/h (0.6 mph)*1
or 1 mph (1.6 km/h)*2 each time the
switch is pressed
Large adjustment: The speed will con-
tinue to change while the switch is held.

matically canceled in the following situa-
tions:
●Actual vehicle speed is more than
approximately 16 km/h (10 mph)
below the set vehicle speed.
●Actual vehicle speed falls below
approximately 30 km/h (20 mph).
●VSC is activated.
●TRC is activated for a period of time.
●When the VSC or TRC system is
turned off.
●Pre-collision braking is activated.
●When the shift lever is in N or the
clutch pedal is depressed for a certain
amount of time or more.
●The parking brake is operated.
If constant speed control mode is auto-
matically canceled for any reasons other
than the above, there may be a malfunc-
tion in the system. Contact any autho-
rized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer.
■The Dynamic Radar Cruise Control
with Road Sign Assist may not
operate properly when
As the Dynamic Radar Cruise Control
with Road Sign Assist may not operate
properly in conditions in which RSA may
not operate or detect correctly
(→P.194), when using this function,
make sure to check the speed limit sign
displayed.
In the following situations, the set speed
may not be changed to the recognized
speed limit by pressing and holding the
“+RES”/“-SET” switch.
●If speed limit information is not avail-
able
●When the recognized speed limit is
the same as the set speed
●When the recognized speed limit is
outside of the speed range that the
dynamic radar cruise control system
can operate
■Brake operation
A brake operation sound may be heard
and the brake pedal response may
change, but these are not malfunctions.
■Warning messages and buzzers for
dynamic radar cruise control
Warning messages and buzzers are
used to indicate a system malfunction or
to inform the driver of the need for cau-
tion while driving. If a warning message
is shown on the multi-information dis-
play, read the message and follow the
instructions. (→P.158, 323)
■When the sensor may not be cor-
rectly detecting the vehicle ahead
In the case of the following and depend-
ing on the conditions, operate the brake
pedal when deceleration of the system
is insufficient or operate the accelerator
pedal when acceleration is required.
As the sensor may not be able to cor-
rectly detect these types of vehicles, the
approach warning (→P.187) may not be
activated.
●Vehicles that cut in suddenly
●Vehicles traveling at low speeds
●Vehicles that are not moving in the
same lane
●Vehicles with small rear ends (trailers
with no load on board, etc.)
●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.)
