In this case, the speed limit signs dis-
played on the multi-information display
and navigation system display may dif-
fer.
In the following situations, the RSA
system will output a warning to
notify the driver.
 If the vehicle speed exceeds the
speed warning threshold of the
speed limit sign displayed on the
display, the sign display will be
emphasized and a buzzer will
sound.
 When the RSA system detects a
no-entry sign and determines
that the vehicle has entered the
no-entry area based on the map
information of the navigation sys-
tem, the no-entry sign displayed
on the multi-information display
will flash and a buzzer will
sound. (Vehicles with a naviga-
tion system)

Dynamic radar cruise
control
This dynamic radar cruise con-
trol detects the presence of
vehicles ahead, determines the
current vehicle-to -vehicle dis-
tance, and operates to main-
tain a suitable distance from
the vehicle ahead. The desired
vehicle-to-vehicle distance can
be set by operating the vehi-
cle-to-vehicle distance switch.
Use the dynamic radar cruise
control only on highways and
expressways.
WARNING
■For safe use
●Driving safely is solely the responsi- bility of the driver. Do not overly rely
on this system, and pay careful attention to the surrounding condi-tions in order to ensure safe driving.
●The dynamic radar cruise control provides driving assistance to
reduce the driver’s burden. How- ever, there are limitations to the assistance provided. Read the fol-
lowing items carefully. Do not overly rely on this system and always drive carefully.
Conditions under which the system may not operate correctly: P.313
●Set the speed appropriately accord- ing to the speed limit, traffic flow,
road conditions, weather condi- tions, etc. The driver is responsible for confirming the set speed.

5-4. Using the driving support systems
The actual vehicle-to-vehicle distance
varies in accordance with the vehicle
speed. Also, when the vehicle is
stopped by system control, it will be
stopped at a certain distance from the
preceding vehicle, depending on the
situation, regardless of the setting.
■Operating conditions
●D shift position is selected.
●The desired set speed can be set when the vehicle speed is approxi-
mately 30 km/h (20 mph) or more. (If the vehicle speed is set while driving at below approximately 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
As with normal driving, acceleration can
be performed by depressing the acceler-
ator pedal. After accelerating, the vehi- cle will return to the set vehicle speed. However, while in vehicle-to-vehicle dis-
tance control mode, the vehicle speed may decrease to below the set vehicle speed in order to maintain the distance
from the preceding vehicle.
■When the vehicle is stopped by system control during follow-up cruising
●When the “RES” switch is pressed while the vehicle is stopped by system
control, if the preceding vehicle starts off within approximately 3 seconds, follow-up cruising will resume.
●If the preceding vehicle starts off within approximately 3 seconds of the
vehicle being stopped by system con- trol, follow-up cruising will resume.
■Automatic cancelation of vehicle-to-vehicle distance control mode
In the following situations, vehicle-to- vehicle distance control mode will be canceled automatically:
●When the brake control or output restriction control of a driving support
system operates (For example: Pre- Collision System, drive-start control)
●When the parking brake has been operated
●When the vehicle is stopped by sys-tem control on a steep incline
●When any of the following are detected while the vehicle is stopped by system control:
• The driver’s seat belt is unfastened • The driver’s door is opened• Approximately 3 minutes have
elapsed since the vehicle was stopped
The parking brake may be actived auto-
matically.
The shift position may automatically change to P. ( P.250)

■Preceding vehicles that the sensor
may not detect correctly
In the following situations, depending on the conditions, if the system cannot pro-
vide sufficient deceleration or accelera- tion is necessary, operate the brake pedal or accelerator pedal.
As the sensor may not be able to cor- rectly detect these types of vehicles, the approach warning ( P.313) may not
operate.
●When a vehicle cuts in front of your
vehicle or changes lanes away from your vehicle extremely slowly or quickly
●When changing lanes
●When a preceding vehicle is driving at a low speed
●When a vehicle is stopped in the same lane as the vehicle
●When a motorcycle is traveling in the same lane as the vehicle
■Conditions under which the system may not operate correctly
In the following situations, operate the brake pedal (or accelerator pedal, depending on the situation) as neces-
sary.
As the sensor may not be able to cor- rectly detect a vehicle, the system may
not operate properly.
●When a preceding vehicle brakes sud-
denly
●When changing lanes at low speeds,
such as in a traffic jam
In situations where the vehicle
approaches a preceding vehicle
and the system cannot provide suf-
ficient deceleration, such as if a
vehicle cuts in front of the vehicle, a
warning display will flash and a
buzzer will sound to alert the driver.
Depress the brake pedal to ensure
appropriate vehicle-to-vehicle dis-
tance.
■Warnings may not occur when
In the following situations, the
warning may not operate even
though the vehicle-to-vehicle dis-
tance is short.
 When the preceding vehicle is
traveling at the same speed or
faster than your vehicle
 When the preceding vehicle is
traveling at an extremely low
speed
 Immediately after the vehicle
speed has been set
 When the accelerator pedal is
depressed
When a curve is detected, the vehi-
cle speed will begin being reduced.
When the curve ends, the vehicle
speed reduction will end.
Depending on the situation, the vehicle
speed will then return to the set vehicle
speed.
In situations where vehicle-to-vehicle
distance control needs to operate, such
as when a preceding vehicle cuts in
front of your vehicle, the curve speed
reduction function will be canceled.
