WARNING
●Assisting the driver to judge
proper following distance
The dynamic radar cruise control
determines whether the following
distance 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 judgement.
Therefore, it is absolutely neces-
sary for the driver to remain vigi-
lant 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
does not include functions which
will prevent or avoid collisions
with vehicles ahead of your vehi-
cle. Therefore, if there is ever any
possibility of dange r, 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
Do not use dynamic radar cruise
control in any of the following situ-
ations. Doing so may result in
inappropriate speed control and
could cause an accident resulting
in death or serious injury.
●Roads where there are pedes-
trians, 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
highways
●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
●During emergency towing
●When an approach warning
buzzer is heard often

■Shift position selection (vehi-
cles with a manual transmis-
sion)
Select a shift position according to
the vehicle speed. If the engine
speed is too high or too low, control
may be automatically canceled.
■Automatic cancelation of vehi-
cle-to-vehicle distance control
mode
Vehicle-to-vehicle distance control
mode is automatically canceled in
the following situations.
●Actual vehicle speed falls below
approximately 16 mph (25 km/h).
●VSC is activated.
●TRAC is activated for a period of
time.
●When the VSC or TRAC system is
turned off.
●The sensor cannot detect cor-
rectly because it is covered in
some way.
●Pre-collision brakin g is activated.
●Vehicles with a manual transmis-
sion: When the shift lever is in N
or the clutch pedal is depressed
for a certain amount of time or
more.
If vehicle-to-vehicle distance control
mode is automatically canceled for
any reasons other than the above,
there may be a malfunction in the
system. Contact your Toyota dealer.
■Automatic cancelation of con-
stant speed control mode
Constant speed control mode is
automatically canceled in the follow-
ing situations:
●Actual vehicle speed is more than
approximately 10 mph (16 km/h)
below the set vehicle speed.
●Actual vehicle speed falls below
approximately 20 mph (30 km/h).
●VSC is activated.
●TRAC is activated for a period of
time.
●When the VSC or TRAC system is
turned off.
●Pre-collision braking is activated.
●Vehicles with a manual transmis-
sion: When the shift lever is in N
or the clutch pedal is depressed
for a certain amount of time or
more.
If constant speed control mode is
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
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 di splay, read the
message and follow the instructions.
(  P.185, 490)
■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 these types of vehi-
cles, the approach warning
(  P.229) 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,

2324-5. Using the driving support systems

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
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
decreasing to the set speed after
the vehicle accelerates by
depressing the accelerator pedal

BSM (Blind Spot Moni-
tor)*
The Blind Spot Monitor is a
system that uses rear side
radar sensors installed on
the inner side of the rear
bumper on the left and right
side to assist the driver in
confirming safety when
changing lanes.
WARNING
■Cautions regarding the use of
the system
The driver is solely responsible for
safe driving. A lways drive safely,
taking care to observe your sur-
roundings.
The Blind Spot Monitor is a sup-
plementary function which alerts
the driver that a vehicle is in a
blind spot of the outside rear view
mirrors or is approaching rapidly
from behind into a blind spot. Do
not overly rely on the Blind Spot
Monitor. As the function cannot
judge if it is safe to change lanes,
over reliance could lead to an
accident resulting in death or seri-
ous injury.
As the system may not function
correctly under certain condi-
tions, the driver’s own visual con-
firmation of safety is necessary.
