Jeep 2016 CHEROKEE Operating Information Manual - page 329
ONBOARD DIAGNOSTIC
SYSTEM (OBD II)
Your vehicle is equipped with a sophisticated
onboard diagnostic system called OBD II. This
system monitors the performance of the emis-
sions, engine, and automatic transmission con-
trol systems. When these systems are operat-
ing properly, your vehicle will provide excellent
performance and fuel economy, as well as
engine emissions well within current govern-
ment regulations.
If any of these systems require service, the
OBD II system will turn on the “Malfunction
Indicator Light (MIL).” It will also store diagnos-
tic codes and other information to assist your
service technician in making repairs. Although
your vehicle will usually be drivable and not
need towing, see your authorized dealer for
service as soon as possible.
CAUTION!
•
Prolonged driving with the MIL on could
cause further damage to the emission con-
trol system. It could also affect fuel
economy and driveability. The vehicle
must be serviced before any emissions
tests can be performed.
•
If the MIL is flashing, while the engine is
running, severe catalytic converter dam-
age and power loss will soon occur. Imme-
diate service is required.
REPLACEMENT PARTS
Use of genuine MOPAR® parts for normal/
scheduled maintenance and repairs is highly
recommended to ensure the designed perfor-
mance. Damage or failures caused by the use
of non-MOPAR® parts for maintenance and
repairs will not be covered by the New Vehicle
Limited Warranty.
MAINTENANCE PROCEDURES
The pages that follow contain the
required
maintenance services determined by the engi-
neers who designed your vehicle.
Besides those maintenance items specified in
the fixed “Service and Warranty Handbook”,
there are other components which may require
servicing or replacement in the future.
CAUTION!
•
Failure to properly maintain your vehicle or
perform repairs and service when neces-
sary could result in more costly repairs,
damage to other components or negatively
impact vehicle performance. Immediately
have potential malfunctions examined by
an authorized dealer or qualified repair
center.
