WARNING
■T o av oi d ma lf u nct i on of the radar
sensor
Observe the following precautions. Otherwise, the radar sensor may not
operate properly, possibly leading to
an accident resulti ng in death or seri- ous injury.
●Keep the radar sensor and the
radar sensor cover clean at all times.
Radar sensor
Radar sensor cover
If the front of the radar sensor or the
front or back of t he radar sensor
cover is dirty or co vered with water
droplets, snow, etc., clean it.
Clean the radar sensor and radar
sensor cover with a soft cloth to avoid
damaging them.
●Do not attach acce ssories, stickers
(including transparent stickers) or
other items to the radar sensor, radar sensor cover or surrounding
area.
●Do not subject the radar sensor or
its surrounding area to a strong
impact. If the radar sensor, front grille, or
front bumper has been subjected to
a strong impact, have the vehicle
inspected by any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.

●Do not disassemble the radar sen - sor.
●Do not modify or paint the radar sensor or radar sensor cover.
●In the following cases, the radar sensor must be recalibrated. Con -
tact any authorized Toyota retailer
or Toyota authorized repairer, or any reliable repairer for details.
• When the radar sensor or front grille are removed and installed, or
replaced
• When the front bumper is replaced
■To avoid malfunction of the front camera
Observe the following precautions.
Otherwise, the front camera may not operate properly, possibly leading to
an accident resulting in death or seri -
ous injury.
●Keep the windshield clean at all
times.
• If the windshield is dirty or covered
with an oily film, water droplets, snow, etc., clean the windshield.
• If a glass coating agent is applied to the windshield, it will still be neces-
sary to use the windshield wipers to
remove water dropl ets, etc. from the area of the windshield in front of
the front camera.
• If the inner side of the windshield
where the front camera is installed
is dirty, contac t any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.

WARNING
●Do not attach objects, such as
stickers, transparent stickers, etc.,
to the outer side of the windshield in front of the fron t camera (shaded
area in the illustration).
From the top of the windshield to
approximately 1 cm (0.4 in.) below
the bottom of the front camera

■Situations in which the system may
not operate properly
●In some situations such as the follow-

the radar sensor and front camera,
preventing the syst em from operating properly:
• When a detectab le object is
approaching your vehicle • When your vehicle or a detectable
object is wobbling
• If a detectable object makes an abrupt maneuver (such as sudden swerving,
acceleration or deceleration)
• When your vehicle approaches a detectable object rapidly
• When a detectabl e object is not
directly in front of your vehicle
• When a detectable object is near a
wall, fence, guardrail, manhole cover, vehicle, steel plate on the road, etc.
• When a detectable object is under a
structure • When part of a detectable object is
hidden by an object, such as large
baggage, an umbrella, or guardrail • When multiple detectable objects are
close together
• If the sun or othe r light is shining directly on a de tectable object
• When a detectable object is a shade
of white and looks extremely bright • When a detectable object appears to
be nearly the same color or brightness
as its surroundings • If a detectable object cuts or suddenly
emerges in front of your vehicle
• When the front of your vehicle is hit by water, snow, dust, etc.
• When a very brigh t light ahead, such

WARNING
■Cautions regarding the driving
assist systems
Observe the following precautions, as there are limitations to the assistance
provided by the syst em. Failure to do
so may cause an accident resulting in death or serious injury.
●Assisting the driver to measure fol -
lowing distance
The dynamic radar cruise control with
full-speed range is only intended to
help the driver in determining the fol -
lowing distance bet ween the driver’s
own vehicle and a designated vehicle
traveling ahead. It is not a mechanism
that allows carele ss or inattentive
driving, and it is not a system that can
assist the driver in low-visibility condi-
tions.
It is still necessary for driver to pay
close attention to the vehicle’s sur -
roundings.
●Assisting the driver to judge proper
following distance
The dynamic radar cruise control with
full-speed range determines whether
the following dist ance between the
driver’s own vehicle and a designated
vehicle traveling ahead is within a set
range. It is not capable of making any
other type of judgemen t. Therefore, it
is absolutely necessary for the driver
to remain vigilant and to determine
whether or not there is a possibility of
danger in any given situation.
●Assisting the driver to operate the vehicle
The dynamic radar cruise control with
full-speed range does not include
functions which will prevent or avoid
collisions with vehi cles ahead of your
vehicle. Therefore, if there is ever any
possibility of danger, the driver must
take immediate and direct control of
the vehicle and act appropriately in
order to ensure the safety of all
involved.
■Situations unsuitable for
dynamic radar cruise control
with full-speed range
Do not use dynamic radar cruise con-
trol with full-speed range in any of the
following situations. Doing so may result in inappropriate speed control
and could cause an accident resulting
in death or serious injury.
●Roads where there are pedestrians,
cyclists, etc.
●In heavy traffic
●On roads with sharp bends
●On winding roads
●On slippery roads, such as those
covered with rain, ice or snow
●On steep downhills, or where there
are sudden changes between sharp
up and down gradients
Vehicle speed may exceed the set
speed when driving down a steep hill.
●At entrances to freeways and high - ways
●When weather conditions are bad
enough that they may prevent the sensors from detecting correctly
(fog, snow, sandstorm, heavy rain,
etc.)

speed limit
Press and hold the “-SET” switch.
Dynamic Radar Cruise Control with
Road Sign Assist can be
enabled/disabled in the screen
on the multi-information display.
( →P.186)
■Dynamic radar cruise control with
full-speed range can be set when
●The shift lever is in D.
●The desired set sp eed can be set
when the vehicle speed is approxi-
mately 30 km/h (20 mph) or more. (However, when the vehicle speed is
set while driving at below approxi -
mately 30 km/h [20 mph], the set speed will be set to approximately 30
km/h [20 mph].)
■Accelerating after setting the vehi -
cle speed
The vehicle can accelerate by operating
the accelerator ped al. After accelerat-
ing, the set speed resumes. However, during vehicle-to-vehicle distance con -
trol mode, the vehicle speed may
decrease below the set speed in order to maintain the distance to the preced -
ing vehicle.
■When the vehicle stops while fol -
low-up cruising
●Pressing the “+RES” switch while the
vehicle ahead stops will resume fol - low-up cruising if the vehicle ahead
starts off within approximately 3 sec -
onds after the sw itch is pressed.
●If the vehicle ahead starts off within 3
seconds after your vehicle stops, fol - low-up cruising will be resumed.
■Automatic cancelation of vehicle-
to-vehicle distance control mode
Vehicle-to-vehicle distance control mode is automatically canceled in the
following situations.
●VSC is activated.
●TRC is activated for a period of time.
●When the VSC or TRC system is
turned off.
●The sensor cannot detect correctly
because it is covered in some way.
●Pre-collision braking is activated.
●The parking brake is operated.
●The vehicle is st opped by system con- trol on a steep incline.
●The following are detected when the vehicle has been stopped by system
control:
• The driver is not wearing a seat belt. • The driver’s door is opened.
• The vehicle has been stopped for
about 3 minutes
If vehicle-to-vehicle distance control
mode is automatically canceled for any
reasons other than the above, there
may be a malfuncti on in the system.
Contact any authoriz ed Toyota retailer
or Toyota authorized repairer, or any
reliable repairer.
■Automatic cancelation of constant
speed control mode
Constant speed control mode is auto -
matically canceled in the following situa -
