NOTE
To 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.
Spark plugs
N00940900198
Spark plugs must fire properly for good engine performance
and emission-control.
Do not reuse them by cleaning or regapping. Change them at
the mileage listed in the “WARRANTY AND MAINTE-
NANCE MANUAL”.
Your vehicle may be equipped with iridium tipped spark plugs,
which are identified by marks on the ceramic. They do not
require replacement as frequently as the conventional type
spare plug and will last much longer.NOTE
Use the spark plugs listed under “Engine specifications”
on page 9-8 or plugs that are exactly the same. Other
plugs could cause engine damage, performance problems
or radio noise.

NOTE
At high altitude locations, the idle speed may be higher than the idle speed described in the vehicle emission control informa-
tion label. This is done in order to stabilize the idle speed when the power steering system and other systems operate. It does
not indicate a malfunction.
