EMISSIONS CONTROL SYSTEM MAINTENANCE
The Scheduled Maintenance services listed in bold type
must be done at the times or mileages specified to ensure
the continued proper functioning of the emission control
system. These, and all other maintenance services in-
cluded in this manual, should be done to provide best
vehicle performance and reliability. More frequent main-
tenance may be needed for vehicles in severe operating
conditions, such as dusty areas and very short trip
driving.
Inspection and service should also be done any time a
malfunction is suspected.
NOTE: Maintenance, replacement, or repair of the emis-
sions control devices and systems on your vehicle may be
performed by any automotive repair establishment or
individual using any automotive part that has been
certified pursuant to U.S. EPA or, in the State of Califor-
nia, California Air Resources Board regulations.
MAINTENANCE SCHEDULE
The oil change indicator system will remind you that it is
time to take your vehicle in for scheduled maintenance.
On Non-EVIC equipped vehicles “CHANgE OIL” will
flash in the instrument cluster odometer and a single
chime will sound, indicating that an oil change is neces-
sary.
Based on engine operation conditions the oil change
indicator message will illuminate, this means that service
is required for your vehicle. Have your vehicle serviced
as soon as possible, within the next 500 mi (805 km).
NOTE:
• The oil change indicator message will not monitor the
time since the last oil change. Change your vehicles oil
if it has been 6 months since your last oil change even
if the oil change indicator message is NOT illumi-
nated.
