There are a great many online sites to help people looking for car manuals, and Suzuki Esteem owners are no exception. A good first place to look would be suzuki-forums.com/suzuki-esteem, where fellow Esteem drivers might be able to help.
Other sites deal with car manuals in general, such as ownersmanualsforcars.com, workshop-manuals.com/suzuki, and calameo.com/books, the latter of which offers downloadable PDFs of Suzuki Esteem repair manuals.
Elsewhere, if you can't locate a manual and need advice on repairing your Suzuki Esteem, try posting a question at fixya.com or 2carpros.com, both are advice sites for car-related problems.
YouTube can also provide a few tips on car repairs, including for the Suzuki Esteem, as this user can show you. If you leave a comment under the film, perhaps another driver will answer and help you out:
