The first generation (J100) was introduced in the late 1990s, evolving into the J200 platform for later models, which was also sold as the Chevrolet Optra, Suzuki Forenza, and Vauxhall/Opel Astra in other markets. This manual covers the primary production run of the Lacetti.

Platform Sharing:

The J200 platform, on which many of these Lacetti models are based, was also utilized for the Chevrolet Optra and Suzuki Forenza, indicating shared componentry and service procedures.

Production Period:

The Daewoo Lacetti was produced from 1997 through the mid-2000s, with its lineage continuing under the Chevrolet brand after GM's acquisition of Daewoo.

🏆 Awards & Recognition
