Most electrical power circuits in the sedan, station wagon, and hatchback are protected by fuses. High-current loads are routed through relays. These protective components are housed in distribution boxes located within the engine compartment and the passenger compartment.
The diagram information applies to the first-generation Chevrolet Lacetti (J200), spanning model years 2004 through 2013.
The distribution box covers feature the fuse layout, amperage ratings, and schematic symbols for the protected circuits.
Engine Compartment
The fuse block is located on the left side of the engine compartment, between the coolant reservoir and the battery. Remove the protective cover to gain access.

Auxiliary Relay Modules
To access these modules, open the coin box and remove the two retaining screws using a screwdriver.
Next, carefully disengage the three retaining clips to detach the lower instrument panel trim.
Then, press the release latch to disconnect the hood release handle and completely remove the lower trim panel. The relays are mounted on a bracket attached to the dashboard frame.
The relay modules are now accessible.
Under-Dash Relay Diagram
Component identification: 1 - Battery saver control module; 2 - Turn signal flasher; 3 - Rear fog lamp relay; 4 - Starter interrupt relay (for vehicles with automatic transmission). Depending on the vehicle trim level, a BLOWER RELAY (HVAC blower motor relay) and a DRL RELAY (Daytime Running Lamps relay) may also be installed in this location.
