■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 4 7
• Conditions under which the vehi-
cle-to-vehicle distance control mode may not function correctly:
P. 2 4 8
●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.

2404-5. 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

4-5. Using the driving support systems
Driving
This mode employs a radar to detect the presence of vehicles up to approx-
imately 100 m (328 ft.) ahead, determines the current vehicle-to-vehicle fol-
lowing distance, and operates to maintain a suitable following distance from
the vehicle ahead. The desired vehicle-to-vehicle distance can also be set
by operating the vehicle-to -vehicle distance switch.
When driving on downhill slopes, the vehicle-to-vehicle distance may become
shorter.
Example of const ant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver.
Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed appears
When a vehicle is de tected running ahead of you, the system automatically deceler-
ates your vehicle. When a greater reduction in vehicle speed is necessary, the sys-
tem applies the brakes (the stop lights will come on at this time). The system will
respond to changes in the speed of the vehicle ahead in order to maintain the vehi-
cle-to-vehicle distance set by the driver. Approach warning warns you when the sys-
tem cannot decelerate sufficiently to prevent your vehicle from closing in on the
vehicle ahead.
When the turn signal lever is operated and your vehicle moves to an overtaking lane
while driving at 80 km/h (50 mph) or more, the vehicle will accelerate to help to over-
take a passing vehicle.
The system’s identificat ion of what is an overtaking lane may be determined solely
based on the location of the steering wheel in the vehicle (left side driver position
versus right side driver position.) If the v ehicle is driven to a region where the over-
Driving in vehicle-to-vehicle distance control mode

2424-5. 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.245)
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.

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-

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.200, 480)
■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.244) 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

2484-5. Using the driving support systems
the luggage compartment, etc.)
●Preceding vehicle has an extremely
high ground clearance
■Conditions under which the vehi-
cle-to-vehicle distance control
mode may not function correctly
In the case of the following conditions,
operate the brake pedal (or accelerator
pedal, depending on the situation) as necessary.
As the sensor may not be able to cor-
rectly 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 unstable
●When the vehicle ahead of you decel-
erates suddenly
●When driving on a road surrounded 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 depr essing the accel-
erator pedal
