■Reduced effectiveness of EPS
The effectiveness of EPS is reduced to prevent the system from overheating when
there is frequent steering input over an extended period of time. The steering wheel
may feel heavy as a result. Should this occur, refrain from excessive steering input or
stop the vehicle and turn the engine off. The system should return to normal about
10 minutes.
■GS460: VGRS is disabled in the following situations
●During stopping or the steering wheel has been moved for a long time while
driving at lower speeds.
●After the engine is restarted at less than -22°F (-30°C).
CAUTION
Any of the following conditions may result in an accident which could cause death or
serious injury:
■The ABS does not operate effectively when
●The limits of tire gripping performance have been exceeded.
●The vehicle hydroplanes while driving at high speed on a wet or slick road.
■Stopping distance when the ABS is operating will exceed that of normal condi-
tions
The ABS is not designed to shorten the vehicle’s stopping distance. Always main-
tain a safe distance from the vehicle in front of you in the following situations.
●When driving on dirt, gravel or snow-covered roads
●When driving with tire chains
●When driving over bumps in the road
●When driving over roads with potholes or roads with uneven roads
■TRAC may not operate effectively when
Directional control and power may not be achievable while driving on slippery road
surfaces, even if the TRAC is operating. 
Do not drive the vehicle in conditions where stability and power may be lost.

PCS (Pre-Collision System)
: If equipped
When the radar sensor detects that a frontal collision is highly likely or
even unavoidable, safety systems such as the brakes and seat belts are
automatically engaged to lessen impact and injuries to occupants as well as
vehicle damage.
■Pre-collision seat belts (front seats only)
If the pre-collision sensor detects that a collision is unavoidable, the pre-
collision system will retract the seat belt before the collision occurs.
The same will happen if the driver makes an emergency braking or loses
control of the vehicle. (P. 6 5 )
■Pre-collision brake assist
Applies greater braking force in relation to how strongly the brake pedal is
depressed.
■Pre-collision braking
When there is a high possibility of a frontal collision, the system warns the
driver using a warning light, warning display and buzzer. If the system
determines that a collision is unavoidable, the brakes are automatically
applied to reduce the collision speed. Pre-collision braking can be dis-
abled using the pre-collision braking off button.
■AVS (if equipped)
If the system determines that the collision is unavoidable, the operation of
AV S (P. 199) helps prevent the vehicle front from going down when
hard brakes are applied.

■DVD video disc information
●DVD video discs
Digital Versatile Disc that holds video. DVD video discs have adopted
“MPEG2”, one of the world standards of digital compression technologies. The
picture data is compressed by 1/40 on average and stored. Variable rate
encoding technology in which the volume of data assigned to the picture is
changed depending on the picture format has also been adopted. Audio data is
stored using PCM and Dolby digital, which enables higher quality of sound. Fur-
thermore, multi-angle and multi-language features will also help you enjoy the
more advanced technology of DVD video.
●Viewer restrictions
This feature limits what can be viewed in conformity with the level of restrictions
of the country. The level of restrictions varies depending on the DVD video disc.
Some DVD video discs cannot be played at all, or violent scenes are skipped or
replaced with other scenes.
Level 1: DVD video discs for children can be played.
Level 2-7: DVD video discs for children and G-rated movies can be played.
Level 8: All types of DVD video discs can be played.
●Multi-angle option
You can enjoy the same scene from different angles.
●Multi-language option
You can select the subtitle and audio languages.
●Region codes
The region codes are found on DVD players and DVD discs. If a DVD video
disc does not have the same region code as the DVD player, you cannot play
the disc on that DVD player. (P. 2 9 8 )

■CD-R and CD-RW discs
●CD-R/CD-RW discs that have not been subject to the “finalizing process” (a
process that allows discs to be played on a conventional CD player) cannot be
played.
●It may not be possible to play CD-R/CD-RW discs recorded on a music CD
recorder or a personal computer because of disc characteristics, scratches or
dirt on the disc, or dirt, condensation, etc. on the lens of the unit.
●It may not be possible to play discs recorded on a personal computer depend-
ing on the application settings and the environment. Record with the correct
format. (For details, contact the appropriate application manufacturers of the
applications.)
●CD-R/CD-RW discs may be damaged by direct exposure to sunlight, high
temperatures or other storage conditions. The unit may be unable to play dam-
aged discs.
●If you insert a CD-RW disc into the MP3/WMA player, playback will begin
more slowly than with a conventional CD or CD-R disc.
●Recordings on CD-R/CD-RW cannot be played using the DDCD (Double
Density CD) system.
CAUTION
■DVD video precaution
Conversational speech on some DVDs is recorded at a low volume to emphasize
the impact of sound effects. If you adjust the volume assuming that the conversa-
tions represent the maximum volume level that the DVD will play, you may be star-
tled by louder sound effects or when you change to a different audio source.
Loud sounds may have a significant impact on the human body or pose a driving
hazard. Keep this in mind when you adjust the volume.
