Dolby Surround Pro Logic II
Dolby Surround Pro Logic II is a further development of the previous version of the system and provides enhanced
sound quality. The improved sound is particularly apparent to passengers in the rear seat.
Dolby Surround Pro Logic II, together with a center speaker in the dashboard, offers you a sound experience very
close to a live performance. The normal left-right stereo channels are divided to left-center -right. In addition, surround
sound is produced by the rear speakers. This surround sound mirrors the ambience of a concert hall.

Three-way catalytic converter
Three-way catalytic converter - general information
Keep your engine properly tuned. Certain engine malfunctions, particularly involving the electrical, fuel or distributor
ignition systems, may cause unusually high three-way catalytic converter temperatures. Do not continue to operate your
vehicle if you detect engine misfire, noticeable loss of power or other unusual operating conditions, such as engine
overheating or backfiring. A properly tuned engine will help avoid malfunctions that could damage the three-way
catalytic converter.
Do not park your vehicle over combustible materials, such as grass or leaves, which can come into contact with the
hot exhaust system and cause such materials to ignite under certain wind and weather conditions.
Excessive starter cranking (in excess of one minute), or an intermittently firing or flooded engine can cause three-way
catalytic converter or exhaust system overheating.
