Driver Information
iii
WABCO
Maintenance Manual MM-1306 (Revised 08-18)
WARNING
If the driver accelerates to a faster speed than the one set to
overtake a vehicle, OnGuard™ CMS will return to the last
stored speed once the driver removes his/her foot from the
accelerator pedal. The driver must be aware of the last stored
speed to make sure that the vehicle can remain in control or
deactivate the system. Failure to do so can result in serious
personal injury or death, and/or severe property damage.
WARNING
OnGuard™ CMS may take a few moments to adjust to the
selected speed. Adjust the speed as necessary to
accommodate the current road, traffic and weather conditions.
Use care to avoid dramatic acceleration or deceleration of the
vehicle which can lead to a loss of control. Serious personal
injury or death, and/or severe property damage can result.
WARNING
Using the “Resume” option will return the vehicle to the last
stored set speed. It is the driver’s responsibility to be aware of
what the last stored speed is and ensure it is safe and legal for
the current road, traffic and weather conditions. Failure to do
so can result in serious personal injury or death, and/or severe
property damage.
System Functions and Miscellaneous
Information
WARNING
Always keep the path of the radar clear of obstructions. Snowy
and muddy conditions can cause the radar to become blocked
or debris to get between the fascia and radar. Always remove
snow, mud or other debris from the front of the fascia and
between the fascia and radar immediately to ensure proper
radar operation. Do not allow the installation of bumpers,
shields, deflectors, guards or other such items in front of the
radar area. Do not allow items to block the radar or 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
The OnGuard™ CMS requires time to recognize an object or
potential obstacle. An object moving at a speed of
approximately 20 mph or more may not be recognized in
enough time to produce a warning or brake the vehicle. Never
wait for the OnGuard™ CMS to intervene when a potentially
hazardous situation arises. The driver must always monitor
traffic and apply the brakes, if needed, to avoid a crash.
Failure to do so can result in serious personal injury or death,
and/or severe property damage.
System Malfunction Information
WARNING
Do not allow the fascia to become blocked by any foreign
matter (dirt, snow, ice, stickers etc.), otherwise a system fault
will occur and the OnGuard™ CMS will be disabled. If the
system becomes disabled, immediately inspect the
OnGuard™ CMS fascia for a blockage and correct it as
necessary. Whether or not the radar is working correctly, it is
the driver’s responsibility to apply the brakes when necessary
to maintain vehicle control. Failure to do so can result in
serious personal injury or death, and/or severe property
damage.
WARNING
If the OnGuard™ CMS is not correctly tracking vehicles that
are in your lane or is tracking vehicles that are not in your lane,
this may be due to radar operational issues. Typically, these
are radar operational issues that can result from the following
problems:
앫
Debris (dirt, snow, ice) on the radar fascia or between the
fascia and the radar sensor. This must be removed.
앫
A loose radar sensor or one that is not tightly secured on
the mounting bracket.
앫
The radar sensor may be too close to or actually contacting
the bumper as mounted. There should be at least 1/4 inch
of clearance between the fascia, radar sensor or bracket
and the bumper.
앫
Radar interference from other radar sources or strong radar
reflections.
