VORAD VS-400 System
WARNING
The VORAD VS-400 System is intended solely as
an aid for an alert and conscientious professional
driver. It is not intended to be relied upon to op-
erate a vehicle. Use the system in conjunction
with rearview mirrors and other instruments to
safely operate the vehicle. Operate a vehicle
equipped with the VS-400 System in the same
safe manner as if the CWS were not present.
The VS-400 System is not a substitute for safe,
normal driving procedures, nor will it compen-
sate for any driver impairment such as drugs,
alcohol, or fatigue.
The VS-400 System may provide little or no warn-
ing of hazards such as pedestrians, animals, on-
coming vehicles, or cross traffic.
Failure to drive safely and use the system prop-
erly could result in personal injury and/or death
and severe property damage.
The VORAD VS-400 system is an on-board radar
system that monitors traffic conditions, warning the
driver of potentially hazardous driving situations.
The collision warning system (CWS) tracks objects
ahead of the vehicle, warning the driver with visual
and audible indicators whenever following distances
become unsafe.
SmartCruise® adjusts the vehicle’s cruise speed in
order to match the speed of traffic ahead, allowing
the driver to maintain a safe following distance while
cruise control is engaged.
The optional side object detection system warns of
unsafe lane changes by detecting vehicles that may
be difficult to see in adjacent lanes.
The VORAD VS-400 system performs in fog, rain,
snow, dust, smoke, and darkness. The VS-400 sys-
tem becomes active whenever the ignition key is
switched to ON.
Driver Interface Unit
The driver interface unit (DIU) provides visual and
audible alerts, along with system status information.
The DIU also provides an interface for changing sys-
tem settings. Menu selections are made by pressing
the up and down arrow buttons, and the OK button.
See
Fig. 6.1 .
The following warning and indicator lights illuminate
on the DIU:
•
Red: illuminates with the collision alert
•
Yellow: illuminates with 3-, 2-, and 1-second
following distance alerts
•
Orange: illuminates when a system failure oc-
curs
•
Blue: illuminates when information is available
Immediately after the ignition switch is turned to ON,
the DIU initializes a self-test routine. During the ini-
tialization, the VORAD screen displays and all lamps
illuminate for approximately three seconds, along
with a power-up tone. When the initialization is com-
plete, the DIU displays the VS-400 system configura-
tion screen. See
Fig. 6.2 .
Menu Selections
IMPORTANT: The display of a menu item is
overridden whenever conditions require an alert
or collision warning to be displayed.
After initialization, the menu screen is displayed.
Scroll to the desired menu item by pressing an arrow
button, then press the OK button to select the item.
See
Fig. 6.3 . If the driver does not make a selection
within 30 seconds, or the vehicle begins to move, the
DIU reverts to the system status display.
