Self-correcting.)
Cold Start Valve re-located.
New Lighting of instrument panel. (3W halogen bulb.)
Warning Lamp for"Check Engine". (Emission control parts of fuel injection
system and ignition system.)
New Ignition System. (EZ 116K)
Lighter Weight Final Drive Housing.
Aluminum Differential Cover.
New Steering Wheel.
Blackpainted Steel Wheel.
New Full-sized Hub Cap.
Rear Seat Belts Unlock from top of clip.
Child Seat Attachment points added.
Rear Head Rests.
Right Hand Side Mirror is convex.
New Rear Seat Back Rest in Wagon.
Hope some of this may be helpful.

| My Haynes manual only covers through 1988 models. Apparently there
| were significant changes made in 1989. Mine is an 89 Volvo GL
| sedan....was wondering how much of the info in my 82-88 Haynes manual
| is valid also for 89. Particularly the electrical system?
