two- to three-second following interval behind
another vehicle in the same lane. If you are
within a two-second following interval and closing
on the vehicle ahead, a warning tone will also
sound.
11.
The red alert light illuminates, along with the yel-
low and orange alert lights, when you are less
than one second behind a vehicle. If the vehicle
ahead is opening the interval, no tone will sound.
If you are closing the interval, double tones will
sound. Within a 1/2-second or less following in-
terval, opening or closing, the tones will repeat
twice per second.
12.
If a stationary vehicle or object, or an object
moving at least 20 percent slower than your ve-
hicle is detected within 220 feet (67 meters) and
within three seconds, all three alert lights will illu-
minate and the double tones will sound. This
warning overrides all others and is not affected
by the range control knob setting.
IMPORTANT: The detection range will be re-
duced during a sharp turn.
13.
If your vehicle is traveling less than 5 mph
(8 km/h) and an object is detected less than 15
feet (4.5 meters) in front of your vehicle and the
closing rate is less than 2 mph (3 km/h) but more
than 1/2 mph (1 km/h), the yellow alert light will
illuminate and a low-frequency double tone will
sound.
NOTE: All warnings apply only to objects within
the maximum detection range and in your lane.
Proximity alert tones and vehicle-closing one- to
two-second following interval tones are config-
ured items. All tones are disabled in sharp turns
or when the brakes are applied. If the configura-
tion permits, the three-second alert level may be
adjusted with the range control knob. A single
low-frequency tone sounds when a system fail-
ure is detected. A medium-frequency tone
sounds when the volume control level is
changed. Successful downloading of Vehicle
Information Management System (VIMS) data
will cause a double tone to sound. Unsuccessful
downloading will cause a low-frequency tone to
sound.
14.
A failure of the optional side sensor(s) will cause
a continuous red light on the side sensor display
to appear.
EVT–300 Side Sensor Display
1.
The yellow indicator light illuminates continuously
when no vehicle is detected by the side sen-
sor(s). See Fig. 2.46.
2.
The ambient light sensor senses lighting condi-
tions and automatically adjusts the intensity of
indicator and alert lights.
3.
The red alert light illuminates when objects are
detected by the side sensor(s). If the right turn
signal is activated and the side sensor detects
an object, the red alert light will illuminate and
the DDU speaker will sound a high-frequency
double tone. This tone is sounded only once per
activation of the turn signal. The red light will
also illuminate and stay on if a failure of the side
sensor is detected. If objects are temporarily un-
able to be detected during heavy rain, both the
red and yellow lights will illuminate.
