APPENDIX A - RADAR MOUNTING AND INSTALLATION
Appendix A
Mounting the Bendix™ FLR-25™ Radar Sensor

GENERAL

Improper use of the Bendix® Fusion™ system include repositioning from the original production line installation.
Under no circumstances should the radar be removed or repositioned. The assembly shall always be
mounted in the original OEM location. Failure to do so may result in a collision causing property damage,
serious injuries, or death. If this location is not in the center of the vehicle, the mounting offset will need to
be programmed through Bendix® ACom® PRO™ Diagnostic Software.

Vehicle equipment, including bumpers, deer guards, etc., must not infringe upon the
zone used by the radar sensor to emit and receive radar waves. Refer to Appendix
A.3. Failure to comply with this requirement will impair the function of the radar.
Only vehicle OEM-approved covers and/or cover panels may be installed in front
of the radar.
The radar sensor assembly is mounted to the front of the vehicle using a non-adjustable
bracket. When mounting a radar sensor, the wire harness connector must always point
towards the driver's side of the vehicle.

A.1 Vehicle Applications
The radar sensor can be mounted and installed only on vehicles that have the Bendix Fusion system already installed.

A.2 Replacement Parts
Replacement parts exist for the components shown below. Parts are available from any Bendix authorized parts supplier.

Radar Sensor

Radar Bracket
Provide the bracket part number (see label/stamp) when ordering replacements.
Bracket will include three (3) mounting screws and the clinch nuts.

A.2.1 Radar Assembly
This image shows the proper assembly sequence for the radar bracket assembly. Once assembled, the
radar assembly is to be mounted to a defined location at the front of the vehicle with the OEM-approved
cover in place.

Appendix A
Bendix™ FLR-25™ Radar Sensor Mounting Clearance
A.3 Bendix™ FLR-25™ Radar Sensor
Mounting Clearance
CAUTION: Vehicle equipment, including bumpers,
deer guards, etc. should not infringe upon the zone
used by the radar sensor shown in Figure 1 to emit
and receive radar waves. Failure to comply with this
requirement may impair the function of the collision
mitigation system. Bendix recommends to only use
OEM-approved and supplied radar covers with our
radar products. OEM-supplied radar covers have been
tested and approved for radar operation with minimum
degradation or attenuation of the radar signal. Nonapproved radar covers may lead to degradation of the
driver assistance system. To qualify a new radar cover
design, please contact the vehicle OEM.

For proper operation of the FLR-25 Radar Sensor, adhere
to the following guidelines:
•
•

NOTE: Bendix does not certify nor offer warranty on
Bendix® Wingman® systems where system performance
is affected by obstructions of any kind. Furthermore,
Bendix will not certify or approve of any third-party bumper
guards mounted on the front of the vehicle. Bendix does
NOT recommend the removal of an Advanced Driver
Assistance System (ADAS) from a vehicle. This document
gives general guidelines that will work for most vehicles;
exceptions may exist.

The radar sensor assembly should be OEM-installed
on the vehicle following all OEM specifications.
The radar’s field of view must NOT have interference
from any other vehicle components such as bumpers,
cow-catcher bumpers, engine blankets, seasonal
decorations, or any other commonly mounted frontof-vehicle components. The radar signal is emitted
from the front of the sensor with a spreading beam.
The approved OEM-provided radar cover is the only
item that is to be placed in front of the radar. In order
to ensure that no adverse interference is experienced
from bumpers or other nearby vehicle equipment, a
suitable clearance must be maintained around the
radar. This clearance must be maintained regardless if
the vehicle is stationary or in motion. See the diagram
below for a general guide and an example of how to
calculate the zone required. The front of the radar
may not be accessible to measure from; it may be
behind the OEM radar cover. The shaded dark gray
area below is the projected radar cone.

Measure from the raised
surface at the front of the radar

Keep all deer and moose guards,

For proper sensor performance,
the areas in front of and around the

to be kept free of any materials or
objects that may disturb the radar
function.
The only exceptions are
OEM‑approved covers.
