Known issues on the 2004 Optra. One owner complaint is on record for this model year, and it concerns the exterior lighting. Lamp circuits are among the more tedious faults to chase on any car, since the failure can sit in a bulb, a socket, a ground, a switch or a splice, and this manual carries the wiring diagrams and circuit tests that separate those possibilities. The rest of the book handles the twin-cam four, its fuel and cooling systems, the transmission, the brakes and the suspension, with torque values and clearances given throughout.
