pped with an emission-
control system that me
ets all the requirements

da. The emission-con-
trol system is made of:  a positive crankcase ventilation system  an evaporative emission-control system  an exhaust emission-control system

done at the time or
mileage specified in the “WARRANTY AND MAINTENANCE MANUAL”. These, and all the other “general” mainte-nance services listed in this manual, need to be performed to keep your vehicle running properly and reliably.You should also have an inspection and ser- vice any time you
suspect a malfunction.

Emission-control system maintenance
NOTE
 To meet government
regulations and pro-
mote cleaner air, your
vehicle is equipped
with an onboard diagnostic system (OBD).The engine electroni
c control module that
controls OBD functions
stores various data
(especially about th
e exhaust emissions).
This data will be erased if the battery cable is disconnected, which c
ould make a rapid
diagnosis difficult.
Do not disconnect the
battery cable when the engine malfunction indicator (“SERVIC
E ENGINE SOON” or
“Check engine light”) is ON.
