Known issues on the 1998 S320. The complaint record for the wider 1998 S-Class line holds one entry, and it concerns tires. That makes wheel and tire service, along with the suspension and alignment settings that affect tire wear, a sensible place to start in this manual. The manual gives procedures and specifications for them, and wheel fastening is covered with torque values. The inline-six, the brakes and the body electrical system are covered too, with wiring diagrams and diagnostics.
