Maintenance Manual MM-1306 (Revised 08-18)
OnGuard™ CMS is designed to detect and track common size
automobiles and trucks with metal surfaces. It is not designed
to detect smaller objects such as pedestrians, narrow
vehicles, motorcycles, mopeds, bicycles, or similar sized
items. It also cannot detect vehicles of unusual shape or with
limited metal surfaces, such as recreational vehicles,
horse-drawn buggies, or logging trailers. The OnGuard™
system may provide little or no warning of these objects in the
vehicle’s path. It is the driver’s responsibility to be aware of
these objects and apply the brakes as necessary to avoid an
accident.
It is always the driver’s responsibility to apply the brakes, if
needed, to avoid an accident. Never wait for an OnGuard™
CMS warning before applying the brakes. Failure to apply the
brakes when needed can result in serious personal injury, or
death, and/or severe property damage.
System-Function Information
WARNING
Once the driver applies the brake, the OnGuard™ CMS will be
disabled and no longer provide braking intervention. It is the
driver’s responsibility to maintain a safe speed and distance
from other vehicles and brake as necessary to maintain
vehicle control. Failure to apply the brakes when necessary
can result in serious personal injury or death, and/or severe
property damage.
WARNING
The driver is responsible for selecting a safe and legal speed
setting that is appropriate for the traffic, road surface and
weather conditions. Adjust the speed setting as necessary
when driving in reduced visibility or potentially slick
conditions. Driving with the OnGuard™ CMS at a speed that is
inappropriate for following a vehicle safely can lead to an
accident. Serious personal injury or death, and/or severe
property damage can result.
WARNING
While the OnGuard™ CMS is in System/Radar Alignment
mode, the system will not track vehicles or operate. Make sure
that the Service Alignment procedure is completed before
releasing the vehicle from service. Failure to do so can result
in serious personal injury or death, and/or severe property
damage.
WARNING
If a potential collision is developing and the driver does not
take action to decelerate the vehicle, the OnGuard™ CMS
sounds an alert, automatically de-throttles the engine, and
sends a message to the ABS ECU requesting foundation brake
application to provide up to 0.35g of braking power. (For
information about the ABS system, refer to the latest ABS
maintenance manual available from Literature On Demand at
www.wabco-auto.com.) The driver must still apply the brakes
to provide additional braking force to help avoid an accident.
Failure to apply the brakes when necessary can result in
serious personal injury or death, and/or severe property
damage.
WARNING
Do not allow the installation of bumpers, cattle guards or other
such items in front of the radar area. If the radar is blocked,
the OnGuard™ CMS will have limited or no functionality, which
can lead to an accident. Serious personal injury or death, and/
or severe property damage can result.
WARNING
OnGuard™ CMS automatically becomes active once the
vehicle reaches a speed of 15 mph (24 kph). It does not
provide warning and braking functionality below 15 mph (24
kph). It is the driver’s responsibility, at all times, to use safe
driving techniques, be alert, maintain a proper distance
between vehicles and brake the vehicle, if needed, to avoid a
collision. Never wait for OnGuard™ CMS to provide a warning
or braking before applying the brakes. Failure to do so can
result in serious personal injury or death, and/or severe
property damage.
WARNING
OnGuard™ CMS may initiate forward collision warnings or in
seldom cases unwanted or inappropriate acceleration or
deceleration. In such cases, the driver has to either deactivate
or override the system as necessary to maintain proper vehicle
control. Failure to do so can result in serious personal injury or
death, and/or severe property damage.
