WARNING
■Before using dynamic radar
cruise control with full-speed
range
●Driving safely is the sole responsi -
bility of the driver. Do not rely solely
on the system, and drive safely by always paying careful attention to
your surroundings.
●The dynamic radar cruise control
with full-speed range provides driv -
ing assistance to reduce the driver’s burden. However, there are
limitations to the assistance pro -
vided.
Read the following conditions care -
fully. Do not overly rely on this system
and always drive carefully.

• Conditions under which the vehicle- to-vehicle distance control mode
may not function correctly: →P.387
●Set the speed appropriately
depending on the speed limit, traffic
flow, road conditions, weather con - ditions, etc. The driver is responsi -
ble for checking the set speed.
●Even when the system is function -
ing normally, the condition of the
preceding vehicle as detected by the system may differ from the con -
dition observed by the driver.
Therefore, the dri ver must always remain alert, assess the danger of
each situation and drive safely.
Relying solely on this system or assuming the system ensures
safety while driving can lead to an
accident, resulti ng in death or seri- ous injury.
●Switch the dynamic radar cruise control with full-speed range setting
to off, using the cruise control main
switch when not in use.

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.)

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

■The Dynamic Radar Cruise Control
with Road Sign Assist may not
operate properly when (vehicles with RSA)
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.375), when using this function, make sure to check th e speed limit sign
displayed.
In the following situations, the set speed may not be changed t o the recognized
speed limit by pressi ng 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 spe ed 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 ar e not malfunctions.
■Warning messages and buzzers for
dynamic radar cruise control with full-speed range
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 messa ge and follow the
instructions. ( →P.353, 578)
■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 ope rate 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.383) 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.)

The Blind Spot Monitor is a
system that has 2 functions:
 The BSM (Blind Spot Monitor)
function
Assists the driver in making a
decision when changing lanes
 The RCTA (Rear Crossing
Traffic Alert) function (if
equipped)
Assists the driver when backing
up
These functions use the same
sensors.
WARNING
■Cautions regarding the use of the BSM function
The driver is solely responsible for
safe driving. Alwa ys drive safely, tak- ing care to observe your surround -
ings.
The BSM function is a supplementary 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 BSM func -
tion. As the function cannot judge if it is safe to change lanes, over reliance
could lead to an accident resulting in
death or serious injury.
As the system may not function cor -
rectly under certain conditions, the
driver’s own visual confirmation of safety is necessary.
■Cautions regarding the use of the RCTA function
The driver is solely responsible for
safe driving. Always drive safely, tak- ing care to observe your surround -
ings.
The RCTA function is only a supple - mentary function which alerts the
driver that a vehi cle is approaching
from the right or left at the rear of the vehicle. As the RCTA function may
not function correctly under certain
conditions, the driver’s own visual confirmation of saf ety is necessary.
Over reliance on this function may
lead to an accident resulting death or serious injury.
