HANDLING PRECAUTION
Precautions for Blind Spot WarningINFOID:0000000006223856
SIDE RADAR HANDLING
 Side radar for BSW system is located inside the rear bumper.
 Always keep the rear bumper near the side radar clean.
 Do not attach a sticker (including transparent material), install an accessory or paintwork near the side radar.
 Do not strike or damage the areas around the side radar.
 Do not strike, damage, and scratch the side radar, especially the vent seal (gray circular) area, under repair.
PRECAUTIONS FOR BLIND SPOT WARNING
 The BSW system is not a replacement for proper driving procedure and are not designed to prevent contact
with vehicles or objects. When changing lanes, always us e the side and rear mirrors and turn and look in the
direction driver will move to ensure it is safe to change lanes. Never rely solely on the BSW system.
 The BSW system may not provide a warning for v ehicles that pass through the detection zone quickly.
 Do not use the BSW system when towing a trai ler because the system may not function properly.
 Excessive noise (e.g. audio system volume, open vehicle window) will interfere with the chime sound, and it may not be heard.
 The side radar may not be able to detect and activate BSW when certain objects are present such as:
- Pedestrians, bicycles, animals.
- Several types of vehicles such as motorcycles.
- Oncoming vehicles.
- Vehicles remaining in the detection z one when driver accelerate from a stop.
- A vehicle merging into an adjacent lane at a speed approximately the same as vehicle.
- A vehicle approaching rapidly from behind.
- A vehicle which vehicle overtakes rapidly.
 Severe weather or road spray conditions may reduce t he ability of the side radar to detect other vehicles.
 The side radar detection zone is designed based on a standard lane width. When driving in a wider lane, the
side radar may not detect vehicles in an adjacent lane. When driving in a narrow lane, the side radar may
detect vehicles driving two lanes away.
 The side radar are designed to ignore most stationary objects, however objects such as guardrails, walls,
foliage and parked vehicles may occasionally be det ected. This is a normal operating condition.

Insulates where slight movement is present. Ideal for instrument panel applications.
SILICONE GREASE
Used in place of UHMW tape that is be visible or does not fit. Will only last a few months.
SILICONE SPRAY
Used when grease cannot be applied.
DUCT TAPE
Used to eliminate movement.
CONFIRM THE REPAIR
Confirm that the cause of a noise is repaired by test driving the vehicle. Operate the vehicle under the same
conditions as when the noise originally occurred. Refer to the notes on the Diagnostic Worksheet.
Inspection ProcedureINFOID:0000000006226060
Refer to Table of Contents for specific component removal and installation information.
INSTRUMENT PANEL
Most incidents are caused by contact and movement between:
1. Cluster lid A and instrument panel
2. Acrylic lens and combination meter housing
3. Instrument panel to front pillar garnish
4. Instrument panel to windshield
5. Instrument panel mounting pins
6. Wiring harnesses behind the combination meter
7. A/C defroster duct and duct joint
These incidents can usually be located by tapping or moving the components to duplicate the noise or by
pressing on the components while driving to stop the noi se. Most of these incidents can be repaired by apply-
ing felt cloth tape or silicon spray (in hard to reach areas). Urethane pads can be used to insulate wiring har-
ness.
CAUTION:
Do not use silicone spray to isolate a squeak or ra ttle. If you saturate the area with silicone, you will
not be able to recheck the repair.
CENTER CONSOLE
Components to pay attention to include:
1. Shifter assembly cover to finisher
2. A/C control unit and cluster lid C
3. Wiring harnesses behind audio and A/C control unit
The instrument panel repair and isolation pr ocedures also apply to the center console.
DOORS
Pay attention to the:
1. Finisher and inner panel making a slapping noise
2. Inside handle escutcheon to door finisher
3. Wiring harnesses tapping
4. Door striker out of alignment causing a popping noise on starts and stops
Tapping or moving the components or pressing on them while driving to duplicate the conditions can isolate
many of these incidents. You can usually insulate the areas with felt cloth tape or insulator foam blocks to
repair the noise.
TRUNK
Trunk noises are often caused by a loose jack or loose items put into the trunk by the owner.
In addition look for:
1. Trunk lid dumpers out of adjustment
2. Trunk lid striker out of adjustment
3. Trunk lid torsion bars knocking together
4. A loose license plate or bracket
