< SYMPTOM DIAGNOSIS >
NORMAL OPERATING CONDITION
RELATED TO AUDIO
 The majority of the audio malfunctions are the result of outside causes (bad CD, electromagnetic interfer-
ence, etc.). Check the symptoms below to diagnose the malfunction.
 The vehicle itself can be a source of noise if noise prevention parts or electrical equipment is malfunctioning.
Check if noise is caused and/or changed by engine speed, ignition switch turned to each position, and oper-
ation of each piece of electrical equipment, and then determine the cause.
NOTE:
 CD-R is not guaranteed to play because they can c ontain compressed audio (MP3, WMA, AAC, M4A) or
could be incorrectly mastered by the customer on a computer.
 Check if the CDs carry the Compact Disc Logo. If not, the disc is not mastered to the “red book” Compact
Disc Standard and may not play.
Noise resulting from variations in field strength, such as fading noise and multi-path noise, or external noise from trains and other
sources, is not a malfunction.
NOTE:
 Fading noise: This noise occurs because of variations in the field strength in a narrow range due to mountains or buildings bl ocking
the signal.
 Multi-path noise: This noise results from a time difference between the broadcast waves directly from the station arriving at the
antenna and the waves reflected by mountains or buildings.
RELATED TO DVD
The system consistently selects
the wrong voicetag 1. Ensure that the phone book entry name requested matches what was originally stored. This
can be confirmed by using the “List Names” command.
2. Replace one of the names being confused with a new name.
Symptom Solution
Symptom Cause and Counter measure
Cannot play Check if the CD was
inserted correctly.
Check if the CD is scratched or dirty.
Check if there is condensation inside the player, and if there is, wait until the condensation is gone
(about 1 hour) before using the player.
If there is a temperature increase error, the player will play correctly after it returns to the normal
temperature.
If there is a mixture of music CD files (CD-DA data) and MP3/WMA/AAC/M4A files on a CD, only
the music CD files (CD-DA data) will be played.
Files with extensions other than “.MP3”, “.WMA”, “AAC”, “.M4A”, “.mp3”, “.wma”, “.aac” or “.m4a”
cannot be played. In addition, the character codes and number of characters for folder names and
file names should be in compliance with the specifications.
Check if the disc or the file is generated in an irregular format, This may occur depending on the
variation or the setting of MP3/WMA/AAC/M4A writing applications or other text editing applica-
tions.
Check if the finalization process, such as session close and disc close, is done for the disc.
Check if the CD is protected by copyright.
Disks recorded in live file system format are not supported. (For Microsoft Windows Vista, check
the settings.)
Poor sound quality Check if the CD is scratched or dirty.
It takes a relatively long time before
the music starts playing. If there are many folder or file levels on the MP3/WMA/AAC/M4A CD, or if it is a multisession disc,
some time may be required before the music starts playing.
Music cuts off or skips The writing software and hardware combination might not match, or the writing speed, writing
depth, writing width might not match the specifications. Try using the slowest writing speed.
Skipping with high bit rate files Skipping may occur with large quantities if data such as for high bit rate data.
Move immediately to the next song
when playing When a non-MP3/WMA/AAC/M4A file has been given an extension of “.MP3”, “.WMA”, “AAC”,
“.M4A” “.mp3”, “.wma”, “.aac” or “.m4a”, or when play is prohibited by copyright protection, the
player will skip to the next song.
The songs do not play back in the
desired order. The playback order is the order in which the files were written by the software, so the files might
not play in the desired order.

rning/Lane Departure PreventionINFOID:0000000006223714
LANE CAMERA UNIT HANDLING
To keep the proper operation of the LDW/LDP systems and prevent a system malfunction, be sure to observe
the following:
 Always keep the windshield clean.
 Do not attach a sticker (including transparent materi al) or install an accessory near the lane camera unit.
 Do not place reflective materials, such as white paper or a mirror, on the instrument panel. The reflection of
sunlight may adversely affect the lane camera unit capability of detecting the lane markers.
 Do not strike or damage the areas around the lane camera unit.
 Do not touch the camera lens.
 Do not remove the screw located on the lane camera unit.
LANE DEPARTURE WARNING (LDW)
 LDW system is only a warning device to inform the dr iver of a potential unintended lane departure. It will not
steer the vehicle or prevent loss of cont rol. It is the driver’s responsibility to stay alert, drive safely, keep the
vehicle in the traveling lane, and be in control of the vehicle at all times.
 LDW system will not operate at speeds below approximat ely 70 km/h (45 MPH) or if it cannot detect lane
markers.
 Excessive noise will interfere with the warning chime sound, and the chime may not be heard.
 LDW system may not function properly under the following conditions:
- On roads where there are multiple parallel lane marker s; lane markers that are faded or not painted clearly;
yellow painted lane markers; non-standard lane markers; or lane markers covered with water, dirt or snow,
etc.
- On roads where the discontinued lane markers are still detectable.
- On roads where there are sharp curves.
- On roads where there are sharply c ontrasting objects, such as shadows, snow, water, wheel ruts, seams or
lines remaining after road repairs. (The LDW syst em could detect these items as lane markers.)
- On roads where the traveling lane merges or separates.
- When the vehicle's traveling direction does not align with the lane marker.
- When traveling close to other vehicle in front of the vehicle, which obstructs the lane camera unit detection
range.
- When rain, snow or dirt adheres to the wi ndshield in front of the lane camera unit.
- When the headlights are not bright due to dirt on the lens or if the aiming is not adjusted properly.
- When strong light enters the lane camera uni t. (For example, the light directly shines on the front of the vehi-
cle at sunrise or sunset.)
- When a sudden change in brightness occurs. (For exampl e, when the vehicle enters or exits a tunnel or
under a bridge.)
LANE DEPARTURE PREVENTION (LDP)
 LDP system will not steer the vehicle or prevent loss of control. It is the driver’s responsibility to stay alert,
drive safely, keep the vehicle in the traveling lane, and be in control of vehicle at all times.
 LDP system is primarily intended for use on well-dev eloped freeways or highways. It may not detect the lane
markers in certain roads, weather or driving conditions.
 Using the LDP system under some conditions of road, lane marker or weather, or when driver change lanes
without using the turn signal could lead to an unexpect ed system operation. In such conditions, driver needs
to correct the vehicle's direction with dr iver's steering operation to avoid accidents.
 When the LDP system is operating, avoid excessive or sudden steering maneuvers. Otherwise, driver could
lose control of the vehicle.
 The LDP system will not operate at speeds below approxim ately 70 km/h (45 MPH) or if it cannot detect lane
markers.
 The LDP system may not function properly under the following conditions, and do not use the LDP system:
- During bad weather (rain, fog, snow, wind, etc.).
- When driving on slippery roads, such as on ice or snow, etc.
- When driving off-road such as on sand or rock, etc.
- When driving on winding or uneven roads.
- When there is a lane closure due to road repairs.
- When driving in a makeshift lane.
- When driving on roads where the lane width is too narrow.

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.
