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.

METHOD OF STARTING
CAUTION:
Start condition of on board self-diagnosis
ICC system OFF
DCA system OFF
Vehicle speed 0 km/h (0 MPH)
1. Turn the ignition switch OFF.
2. Start the engine.
3. Wait for 5 seconds after starting the engine. Push up the RESUME/ACCELERATE switch 5 times and push down the
SET/COAST switch 5 times within 10 seconds.
NOTE:
If the above operation cannot be performed within 10 seconds
after waiting for 5 seconds after starting the engine, repeat the
procedure from step 1.
4. The DTC is displayed on the set vehicle speed indicator (1) on the ICC system display on the information display when the on board self-diagnosis starts. Refer to DAS-38, "
DTC Index".

WHEN THE ON BOARD SELF-DIAGNOSIS DOES NOT START
If the on board self-diagnosis does not start, check the following items.
HOW TO ERASE ON BOARD SELF-DIAGNOSIS
1. Turn the ignition switch OFF.
2. Start the engine, and then start the on board self-diagnosis.
3. Press the CANCEL switch 5 times, and then press the DIS-
TANCE switch 5 times under the condition that the on board
self-diagnosis starts.
NOTE:
Complete the operation within 10 seconds after pressing the
CANCEL switch first.
If the operation is not completed within 10 seconds, repeat the procedure from step 1.
4. DTC 55 is displayed after erasing. NOTE:
DTCs for existing malfunction can not be erased.
5. Turn ignition switch OFF, and finish the diagnosis.
