■ Warning messages and buzzers for
dynamic radar cruise control with
full-speed range
Warning messages and buzzers are used to
indicate a system malfunction or to inform
the driver of the need for caution while driv-
ing. If a warning message is shown on the
multi-information display, read the message
and follow the instructions.
■ When the sensor may not be correctly
detecting the vehicle ahead
In the case of the following and depending
on the conditions, operate the brake pedal
when deceleration of the system is insuffi-
cient or operate the accelerator pedal
when acceleration is required.
As the sensor may not be able to correctly
detect these types of vehicles, the approach
warning (→P.256) 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 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 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 nec-
essary.
As the sensor may not be able to correctly
detect vehicles ahead, the system may not
operate properly.
● When driving around a curve, on a nar-
row road, or on a bridge, in a tunnel, etc.,
where there are objects on the roadside
● When steering wheel operation or your
position in the lane is unstable
● When the vehicle ahead of you deceler-
ates suddenly
● While the vehicle speed is decreasing to
the set speed after the vehicle acceler-
ates by depressing the accelerator pedal.
