NOTETo meet government regulations and promote cleaner air,
your vehicle is equipped with an onboard diagnostic sys-
tem (OBD). The engine electronic control module that
controls OBD functions stores various data (especially
about the exhaust emissions). This data will be erased if
the battery cable is disconnected, which could make a
rapid diagnosis difficult. Do not disconnect the battery
cable when the engine malfunction indicator (“SERVICE
ENGINE SOON” or “Check engine light”) is on.

and emission-control.
Do not reuse them by cleaning or regapping. Change them at
the mileage listed in the “WARRANTY AND MAINTE-
NANCE MANUAL”. NOTEUse the spark plugs listed under “Engine specifications”

plugs could cause engine damage, performance problems
or radio noise.
