• When driving near a TV tower, broad-
casting station, electric power plant, or 
other location where  strong radio waves 
or electrical noise may be present
■Situations in which the system may not 
operate properly
●In some situations such as the following, a 
vehicle may not be detected by the radar 
sensor and camera sensor, preventing 
the system from operating properly:
• If an oncoming vehicle is approaching  your vehicle
• If a vehicle ahead is a motorcycle or bicy-

• When approaching the side or front of a  vehicle
• If a preceding vehicle has a small rear  end, such as an unloaded truck
• If a preceding vehicle has a low rear end, 
such as a low bed trailer
• If a vehicle ahead is carrying a load which  protrudes past its rear bumper
• If a vehicle ahead has extremely high  ground clearance
• If a vehicle ahead is irregularly shaped,  such as a tractor or side car
• If the sun or other light is shining directly 
on a vehicle ahead
• If a vehicle cuts in front of your vehicle or  emerges from beside a vehicle
• If a vehicle ahead makes an abrupt  maneuver (such as sudden swerving, 
acceleration or deceleration)
• When suddenly cutting behind a preced- ing vehicle
• When a vehicle ahead is not directly in  front of your vehicle
• When driving in incl ement weather such 
as heavy rain, fog, snow or a sandstorm

shines directly into the camera sensor
• When the surrounding area is dim, such 
as at dawn or dusk, or while at night or in 
a tunnel
• After the engine  has 
started the vehicle has not been driven 
for a certain amount of time
• While making a left/r ight turn and for a

2124-5. Using the driving support systems
●Motorcycles traveling in the same lane
●When water or snow thrown up by the 
surrounding vehicles hinders the detect-
ing 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 vehicle-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 nec-
essary. 
As the sensor may not be able to correctly 
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 deceler-
ates 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 acceler-
ates by depressing the accelerator pedal
