■Before using dynamic radar  cruise control
●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 
provides driving assistance to  reduce the driver’s burden. How- 
ever, there are limitations to the 
assistance provided. 
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. 2 6 9 
• Conditions under which the vehi- 
cle-to-vehicle distance control  mode may not function correctly: 
P. 2 7 0
●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 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.
●Switch the dynamic radar cruise 
control setting to off, using the  cruise control main switch when not  
in use.
■Cautions 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.
●Assisting the driver to measure fol-lowing distance 
The dynamic radar cruise control is  
only intended to help the driver in  determining the following 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 conditions. 
It is still necessary for driver to pay  
close attention to the vehicle’s 
surroundings. 

2624-5. Using the driving support systems
WA R N I N G
●Assisting the driver to judge proper  
following distance 
The dynamic radar cruise control  determines whether the following dis- 
tance between the driver’s own vehi-
cle 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 vig- ilant 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 vehi- cles ahead of your vehicle. Therefore,  
if there is ever any possibility of dan-
ger, 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 con- 
trol 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.)
●When there is rain, snow, etc. on the front surface of the radar or  
front camera
●In traffic conditions that require fre-
quent repeated acceleration and 
deceleration
●When your vehicle is towing a 
trailer or during emergency towing
●When an approach warning buzzer 
is heard often 

2644-5. Using the driving support systems 
taking lane is on a different side from wher e the vehicle is normally driven, the vehi- 
cle may accelerate when the turn signal lever is operated in the opposite direction to 
the overtaking lane (e.g., if the driver normally operates the vehicle in a region 
where the overtaking lane is to the right but then drives to a region where the over-
taking lane is to the left, the vehicle may accelerate when the right turn signal is acti-
vated).
Example of acceleration 
When there are no longer any precedi ng vehicles driving slower than the  
set speed
The system accelerates until  the set speed is reached. The system then returns to  
constant speed cruising.
1 Press the cruise control main  
switch to activate the cruise con-
trol.
Dynamic radar cruise control indicator  
will come on and a message will be dis-
played on the multi-information display.  Press the switch again to deactivate the  
cruise control. 
If the cruise control main switch is  pressed and held for 1.5 seconds or  
more, the system turns on in constant 
speed control mode. ( P.267)
2Accelerate or decelerate, with  
accelerator pedal operation, to 
the desired vehicle speed (at or 
above approximately 30 km/h  
[20 mph]) and press the “-SET”  
switch to set the speed.
Cruise control “SET” indicator will come  on. 
The vehicle speed at the moment the  
switch is released becomes the set  speed.
To change the set speed, press the  
“+RES” or “-SET” switch until the 
desired set speed is displayed.

Adjusting the set speed 

2664-5. Using the driving support systems
Select a distance from the table  
below. Note that the distances 
shown correspond to a vehicle 
speed of 80 km/h (50 mph). Vehi-
cle-to-vehicle distance 
increases/decrea ses in accord- 
ance with vehicle speed. 
1 Pressing the cancel switch can- 
cels the speed control.
The speed control is also canceled  
when the brake pedal is depressed.
2 Pressing the “+RES” switch  
resumes the cruise control and 
returns vehicle speed to the set  
speed.
However, cruise control does not  
resume when the vehicle speed is 
approximately 25 km/h (16 mph) or 
less.
When your vehicle is too close to a  
vehicle ahead, and sufficient auto-
matic deceleration via the cruise 
control is not poss ible, the display  
will flash and the buzzer will sound 
to alert the driver. An example of 
this would be if another driver cuts 
in front of you wh ile you are follow- 
ing a vehicle. Depress the brake 
pedal to ensure an appropriate 
vehicle-to-vehicle distance.
■Warnings may not occur when 
In the following in stances, warnings  
may not occur even when the vehi-
cle-to-vehicle distance is small.

■Accelerating 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 preceding 
vehicle.
■Shift position selection 
Select a shift positi on according to the  
vehicle speed. If the engine speed is too 
high or too low, control may be automat- ically canceled.
■Automatic cancelation of vehi- 
cle-to-vehicle distance control

■The Dynamic Radar Cruise Control 
with Road Sign Assist may not  operate properly when 
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.279), when using this function,  make sure to check the speed limit sign  
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.
●If speed limit information is not availa-
ble
●When the recognized speed limit is 
the same as the set speed
●When the recognized speed limit is 
outside of the speed 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 are not malfunctions.
■Warning messages and buzzers for 
dynamic radar cruise control 
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.222, 520)
■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 operate 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.266) 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.)
●Motorcycles traveling in the same lane
●When water or snow thrown up by 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.)
