1998-2004 Cadillac Seville: Year-to-Year Changes

1999 Cadillac Seville: Front seats that give back massage were new this year, but little else changed on Cadillac's sport luxury sedan. The optional system used "rolling" lumbar bolsters that massaged the lower back of a front-seat occupant in 10-minute cycles. Either the SLS or STS model could have Cadillac's optional "adaptive" front seats, with internal air bladders that continuously adjusted to the passenger's body contours. This year's version was heated.

2000 Cadillac Seville: Both engines now ran on regular fuel, not premium. Both Seville models also gained a revised version of GM's OnStar emergency communications/assistance system. The Continuously Variable Road Sensing Suspension now selectively varied shock absorber firmness for both up and down wheel motions, working with StabiliTrak to minimize body lean and front-end "plow" in turns. The StabiliTrak system could now briefly increase steering effort when needed, and brake the front wheels to recover from a 4-wheel-drift type of skid. A new front-seat sensor could deactivate passenger airbags when the presence of a child--or no occupant--was detected. New options included an onboard navigation system and Ultrasonic Rear Parking Assist, which warned of obstacles while the car was backing up.

2001 Cadillac Seville: Seville got an optional e-mail system and auto-reversing power front windows. SLS versions were upgraded with the monochrome appearance introduced at midyear on the short-lived TX7 variant.

2002 Cadillac Seville: A new DVD navigation system with voice recognition was added this year. Newly standard were heated seats and a rear-obstacle-warning system. Added during the 2002 model year was a satellite radio that played commercial-free programs for a monthly fee.

2003 Cadillac Seville: Appearance alterations include a body-color grille for the SLS and standard chrome wheels for the STS. The SLS also gains a standard driver-seat memory and, like the STS, now comes with a power tilt/telescoping steering wheel. Rain-sensing windshield wipers are newly standard for STS.

2004 Cadillac Seville: During the sedan's last model year, the '04 300-hp sporty Seville STS model was dropped to make way for the all-new 2005 STS.
