2504-5. Using the driving support systems
The following types of road
signs are recognized.
A non-official or a recently intro-
duced traffic sign may not be recog-
nized.
In the following situations, the
RSA system will alert the driver.
When the vehicle speed
exceeds the speed warning
threshold of the speed limit
sign displayed, the sign dis-
play will be emphasized and a
buzzer will sound.
 When the RSA system recog-
nizes a do not enter sign and
determines that your vehicle
has entered a no-entry area,
the displayed sign will flash
and a buzzer will sound.
Depending on the situation, traf-
fic environment (traffic direction, speed unit) may be detected
incorrectly and a warning dis-
play may not operate properly.
■Setting procedure
 P. 9 4
■Automatic turn-off of RSA sign
display
In the following si tuations, a dis-
played speed limit sign will stop
being displayed automatically:
●A new sign is not recognized for a
certain distance.
●The road changes due to a left or
right turn, etc.
In the following situ ations, do not
enter, stop and yie ld signs will stop
being displayed automatically:
●The system determines that your
vehicle has passed the sign.
●The road changes due to a left or
right turn, etc.
■Conditions in which the func-
tion may not operate or detect
correctly
In the following si tuations, RSA
does not operate normally and may
not recognize signs, display the
incorrect sign, etc. However, this
does not indicate a malfunction.
●The front camera is misaligned
due to a strong impact being
applied to the sensor, etc.
●Dirt, snow, stickers, etc. are on the
windshield near the front camera.

●The dynamic radar cruise con-
trol with full-speed range pro-
vides driving assistance to
reduce the driver’s burden.
However, there are limitations to
the assistance provided.
Read the following conditions
carefully. Do not overly rely on this
system and always drive carefully.
• When the sensor may not be correctly detecting the vehicle
ahead: P. 2 6 0
• Conditions under which the vehicle-to-vehicle distance con-
trol mode may not function cor-
rectly: P. 2 6 1
●Set the speed appropriately
depending on the speed limit,
traffic flow, road conditions,
weather conditions, etc. The
driver is responsible for check-
ing the set speed.
●Even when the system is func-
tioning normally, the condition of
the preceding vehicle as
detected by the system may dif-
fer from the condition observed
by the driver. Therefore, the
driver must always remain alert,
assess the danger of each situ-
ation and drive safely. Relying
solely on this system or assum-
ing the system ensures safety
while driving can lead to an
accident, result ing in death or
serious injury.
●Switch the dynamic radar cruise
control with full-speed range
setting to off, using the cruise
control main switch when not in
use.

2544-5. Using the driving support systems
This mode employs a radar to detect the presence of vehicles up to
approximately 328 ft. (100 m) ahead, determines the current vehicle-
to-vehicle following distance, and operates to maintain a suitable 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, t he vehicle-to-vehicle distance may
become shorter.
Example of constant speed cruising
●When weather conditions are
bad enough that they may pre-
vent the sensors from detecting
correctly (fog, snow, sand-
storm, heavy rain, etc.)
●When there is rain, snow, etc.
on the front surface of the radar
or front camera
●In traffic conditions that require
frequent repeated acceleration
and deceleration
●When your vehicle is towing a
trailer or during emergency tow-
ing
●When an approach warning
buzzer is heard often

automatically canceled for any rea-
sons 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 mal-
functions.
■Warning messages and buzzers
for dynamic radar cruise con-
trol with full-speed range
Warning messages and buzzers are
used to indicate a system malfunc-
tion or to inform the driver of the
need for caution while driving. If a
warning message is shown on the
multi-information display, read the
message and follow the instructions.
(  P.228, 633)
■When the sensor may not be
correctly detecting the vehicle
ahead
In the case of the following and
depending on the conditions, oper-
ate the brake pedal when decelera-
tion of the system is insufficient or
operate the accelerator pedal when
acceleration is required.
As the sensor may not be able to
correctly detect th ese types of vehi-
cles, the approach warning
(  P.258) 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.)

extremely high ground clearance
■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
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 unsta-
ble
●When the vehicle ahead of you
decelerates suddenly
●When driving on a road sur-
rounded by a structure, such as in
a tunnel or on a bridge
●While the vehicle speed is

The Blind Spot Monitor is a
system that has 2 functions:
The BSM (Blind Spot Moni-
tor) function
Assists the driver in making a
decision when changing lanes
 The RCTA (Rear Cross
Traffic Alert) function
Assists the driver when back-

■Cautions regarding the use of
the BSM function
The driver is solely responsible for
safe driving. Always drive safely,
taking care to o bserve your sur-
roundings.
The BSM function is a supple-
mentary function which alerts the
driver that a vehicle is in a blind
spot of the outside rear view mir-
rors or is approaching rapidly from
behind into a blind spot. Do not
overly rely on the BSM function.
As the function cannot judge if it is
safe to change lanes, over reli-
ance could lead to an accident
resulting in death or serious injury.
As the system may not function
correctly under certain condi-
tions, the driver’s own visual con-
firmation of safety is necessary.
WA R N I N G
■Cautions regarding the use of
the RCTA function
The driver is solely responsible for
safe driving. Always drive safely,
taking care to observe your sur-
roundings.
The RCTA function is only a sup-
plementary function which alerts
the driver that a vehicle is
approaching from the right or left
at the rear of the vehicle. As the
RCTA function may not function
correctly under certain condi-
tions, the driver’s own visual con-
firmation of safety is necessary.
Over reliance on this function may
lead to an accident resulting
death or serious injury.
