The car was significantly upgraded for 2003 (concurrently with the discontinuation of the Continental), & the engines received a boost in power, with the addition of variable valve timing of the intake camshafts, & an electronic throttle controller & accelerator pedal, replacing the traditional mechanical cable-linked system. The exterior received a slight facelift, with HID headlamps, & a revised trunklid with new taillights. One notable addition was the electronic push-button parking brake, similar to the BMW E65 7 Series, replacing the traditional center console mounted hand lever (or foot pedal); another was a touch-screen DVD satellite navigation map system with a THX-certified sound system, the first in an automobile. Limited special edition LSE versions were also available, with revised fascia, body panels, wheels, all red tail lights, & exhaust tailpipe treatments.

Earlier LS models had a mechanical engine cooling fan that was operated with a hydraulic clutch, because the electrical charging system did not have sufficient capacity to carry the additional load of an electric fan. This was changed in the 2003-2006 models, when the fan was switched to an electric one as a result of an improved alternator design.

The 2003-2006 GPS navigation system uses a DVD player mounted in the trunk (under the package tray) to contain the map data.

For the 2006 model year, the LS received a minor facelift, which resembled the LSE fascia & body treatments used in previous model years. The V6-powered model was dropped from the lineup due to poor sales volume. As a result of this change in the lineup, the base MSRP for the Lincoln LS increased from roughly $32,000 in 2004 to $39,945, moving the LS from the entry-level luxury segment into the mid-luxury segment.

The Lincoln LS has received very high marks in occupant protection. The Insurance Institute for Highway Safety has rated the LS as a ''Best Pick'' with a perfect score in their frontal offset crash test. The National Highway Traffic Safety Administration gave the LS almost perfect scores in its side impact & rollover tests. In fact, CNBC rated the LS as “one of the five safest cars of all time.”
