OnGuard
™
Collision Safety
System
Meritor WABCO OnGuard is a forward-looking radar-
based safety system. The system includes forward
collision warning, adaptive cruise control (ACC), and
collision mitigation.
OnGuard equipped vehicles have antilock brakes
(ABS) and automatic traction control (ATC), and ei-
ther roll stability control (RSC) or electronic stability
control (ESC). These systems work together to en-
hance control of the vehicle. Depending on the situa-
tion, any of these features may apply throttle control,
engine brakes, and/or service brakes, as needed.
The front-looking antenna assembly transmits radar
signals to, and receives them back from, objects
ahead of the vehicle. To be detected, vehicles must
be within the radar field of view and provide a sur-
face area that can reflect the radar. The distance,
speed, and angle of the vehicle ahead is calculated,
and the driver is warned of potentially dangerous
situations. The system also warns of stationary ob-
jects to alert the driver of potential obstructions
ahead in their lane.

The Meritor WABCO OnGuard
™
Collision Safety
System is intended solely as an aid for an alert
and conscientious professional driver. It is not
intended to be relied upon to operate a vehicle.
Use the system in conjunction with rearview mir-
rors and other instruments to safely operate the
vehicle. Operate a vehicle equipped with the On-
Guard in the same safe manner as if the CWS
were not present.
The OnGuard Collision Safety System is not a
substitute for safe, normal driving procedures,
nor will it compensate for any driver impairment
such as drugs, alcohol, or fatigue.
Failure to drive safely and use the system prop-
erly could result in personal injury and/or death
and severe property damage.
System Limitations
The OnGuard Collision Safety System may provide
little or no warning of hazards such as pedestrians,
animals, oncoming vehicles, or cross traffic.
OnGuard CMS only brakes for lead vehicles located
directly in front of your vehicle, and does not operate
when vehicle speed is less than 15 mph (25 km/h).
Due to these limitations, the system:
•
will not react and alert the operator to objects
crossing in front of the vehicle or oncoming
traffic;
•
should not be relied on to track lead vehicles
when traveling through a severe curve in the
road. Because of this, ACC is not recom-
mended for use on winding roads;
•
will alert, but not actively brake, on stationary
objects;
•
should not be relied upon to track smaller ob-
jects like motorcycles, mopeds, bicycles, or
pedestrians;
•
should not be relied on to alert drivers to ve-
hicles in an adjacent lane.
OnGuard Display Unit
The OnGuard system controls are located in the dis-
play unit. The display provides visual and audible
warnings and messages, as well as verification of
correct system operation and faults. Menu selections
