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.233) 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.)
●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 vehicl es 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

■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
