*1: Displayed simultaneously with
speed limit.
*2: Contents not recognized.
*3: If the turn signal indicator is not
operated when changing lanes, the
mark does not display.
In the following situations, the RSA
system will notify the driver.
When the vehicle speed exceeds
the speed notification threshold
of the speed limit sign displayed,
the sign display will be empha-
sized and a buzzer will sound.
When the RSA system recog-
nizes a no-entry sign and detects
that the vehicle has entered a
no-entry area based on the map
information of the navigation sys-
tem, the no-entry sign flashes
and a buzzer will sound. (For
vehicles with navigation system)
If it is detected that your vehicle
is overtaking when a no overtak-
ing sign is displayed on the multi-
information display, the dis-
played sign will flash and a steer-
ing wheel will vibrate.

WARNING
QBefore using dynamic radar
cruise control with full-speed range
ODriving 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.
OThe 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.
• When the sensor may not be cor-
rectly detecting the vehicle ahead: P.342

• Conditions under which the vehicle- to-vehicle distance control mode may not function correctly: P.343
OSet 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.
OEven 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 driver 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, resulting in death or seri- ous injury.
OSwitch the dynamic radar cruise control with full-speed range setting to off, using the cruise control main
switch when not in use.

WARNING
QCautions regarding the driving assist systems
Observe the following precautions, as there are limitations to the assistance provided by the system. Failure to do
so may cause an accident resulting in death or serious injury.
OAssisting 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 between the driver’s
own vehicle and a designated vehicle
traveling ahead. It is not a mechanism
that allows careless 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.
OAssisting the driver to judge proper following distance
The dynamic radar cruise control with
full-speed range 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 necessary for the driver
to remain vigilant and to determine
whether or not there is a possibility of
danger in any given situation.
OAssisting 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 vehicles 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.
QSituations 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.
ORoads where there are pedestrians, cyclists, etc.
OIn heavy traffic
OOn roads with sharp bends
OOn winding roads
OOn slippery roads, such as those covered with rain, ice or snow
OOn 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.
OAt entrances to freeways and high- ways
OWhen weather conditions are bad enough that they may prevent the sensors from detecting correctly
(fog, snow, sandstorm, heavy rain, etc.)

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.184)
When the Dynamic Radar Cruise
Control with Road Sign Assist is
operating, while driving down a hill,
the vehicle speed may exceed the
set speed.
In this case, the displayed set vehi-
cle speed will be highlighted and a
buzzer will sound to alert the driver.
QDynamic radar cruise control with
full-speed range can be set when
OThe shift lever is in D.
OThe desired set speed 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].)
QAccelerating after setting the vehi-
cle speed
The vehicle can accelerate by operating
the accelerator pedal. 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.
QWhen the vehicle stops while fol-
low-up cruising
OPressing 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 switch is pressed.
OIf the vehicle ahead starts off within 3
seconds after your vehicle stops, fol-
low-up cruising will be resumed.
QAutomatic cancelation of vehicle-
to-vehicle distance control mode
Vehicle-to-vehicle distance control
mode is automatically canceled in the
following situations.
OVSC is activated.
OTRC is activated for a period of time.
OWhen the VSC or TRC system is
turned off.
OThe sensor cannot detect correctly
because it is covered in some way.
OWhen the brake control or output
restriction control of a driving support
system operates.
(For example: Pre-Collision System,
Drive-Start Control)
OThe parking brake is operated.
OThe vehicle is stopped by system con-
trol on a steep incline.
OThe 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

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.
OIf speed limit information is not avail-
able
OWhen the recognized speed limit is
the same as the set speed
OWhen the recognized speed limit is
outside of the speed range that the
dynamic radar cruise control system
can operate
QBrake operation
A brake operation sound may be heard
and the brake pedal response may
change, but these are not malfunctions.
QWarning 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 message and follow the
instructions. (P.309, 518)

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
Assists the driver when backing
up
These functions use the same
sensors.
WARNING
QCautions regarding the use of the BSM function
The driver is solely responsible for safe driving. Always 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.
QCautions regarding the use of the RCTA function
There is a limit to the degree of recog-
nition accuracy and control perfor- mance that this system can provide, do not overly rely on this system. The
driver is always responsible for pay- ing attention to the vehicle’s sur-roundings and driving safely.
