EMISSIONS TESTING
In some localities, it may be or will become a legal
requirement to ensure that all emissions components and
systems are functioning properly as a part of the test
procedure. The test center accomplishes this by checking
the On Board Diagnostic System system (OBD) with an
electronic scan tool. If your vehicle has recently been
serviced, the OBD system may have been reset to a9not
ready9condition because the OBD system has not had
sufficient time since the servicing to reconfirm that
emissions components are operating properly. In most
cases, a reasonable mix and amount of normal city and
highway driving and at least one overnight-off period
will be required to prepare your vehicle for this check;
however your DaimlerChrysler Motors Corporation
dealer has the equipment and procedures required to
make certain that the OBD system of your vehicle is
ready for the required testing.
ONBOARD DIAGNOSTIC SYSTEM (OBD II)
To meet new government regulations and promote
cleaner air, your vehicle is equipped with a sophisticated
onboard diagnostic system called OBD II. This systemmonitors the performance of the emissions, engine, and
automatic transaxle control systems. When these systems
are operating properly, your vehicle will provide excel-
lent performance and fuel economy, as well as engine
emissions well within current government regulations.
If any of these systems require service, the
OBD II system will turn on the Malfunction
Indicator Light. It will also store diagnostic
codes and other information to assist your
service technician in making repairs. Al-
though your vehicle will usually be driveable and not
need towing, see your dealer for service as soon as
possible.
CAUTION!
Prolonged driving with the light on could cause
further damage to the emission control system. It
could also affect fuel economy and driveability. The
vehicle must be serviced before any state emissions
tests can be performed.

Spark plugs
Spark plugs must fire properly to assure proper engine
performance and emission-control.
Do not reuse spark plugs by cleaning or regapping. Spark
plugs should be replaced at the mileage specified on the
scheduled maintenance chart.
Your vehicle may be equipped with standard type spark
plugs or iridium tipped ones. Iridium tipped spark plugs
are identified by blue marks on the ceramic. They do notrequire replacement as frequently as the conventional
type spark plug and are designed to last much longer.
NOTE: Use the recommended or equivalent spark plugs
listed under ªEngine specificationsº on page 361.
Use of non-recommended plugs will cause engine dam-
age, loss of performance or radio noise.
Ignition cables
The ignition cables should be kept clean, properly con-
nected, and fully seated. Terminals should be fully seated
and should not be removed from the distributor or coil
towers unless they are damaged or cable testing indicates
high resistance or broken insulation. Cracked, damaged,
or faulty cables must be replaced.
Distributor cap and rotor
Check the distributor cap and rotor to maintain proper
function and good emission control.
