Chrysler Voyager 2001, Operating Information Manual

ONBOARD DIAGNOSTIC SYSTEM
(OBD)
Your vehicle is equipped with a sophisticated
onboard diagnostic system called OBD. This sys-
tem monitors the performance of the emissions,
engine, and automatic transaxle control systems.
When these systems are operating properly, your
vehicle will provide excellent performance and
fuel economy, as well as engine emissions well
within current government regulations.
If any of these systems require service, the OBD
system will turn on the Malfunction Indicator Light.
It will also store diagnostic codes and other infor-
mation to assist your service technician in making
repairs. Although your vehicle will usually be
driveable and not need towing, see your Chrysler
International dealer for service as soon as pos-
sible.
CAUTION!
Prolonged driving with the light on could cause
further damage to the emission control system.
It could also affect fuel economy and driveability.
If the indicator light is flashing, severe catalytic
converter damage and power loss will soon occur.
Immediate service is required.
REPLACEMENT PARTS
Use of genuine Mopar parts for normal/scheduled
maintenance and repairs is highly recommended
to insure the designed performance. Damage or
failures caused by the use of non-Mopar parts for
maintenance and repairs will not be covered by
the Chrysler International warranty.
MAINTENANCE PROCEDURES
Engine Oil Requirements — Gasoline
Engines
Checking Oil Level
To assure proper engine lubrication, the engine oil
must be maintained at the correct level. Check the
oil level at regular intervals, such as every fuel
stop.
The best time to check the engine oil level is about
5 minutes after a fully warmed engine is shut off or
before starting the engine after it has sat over-
night.
Checking the oil while the vehicle is on level
ground will improve the accuracy of the oil level
readings. Maintain the oil level between the MIN
and MAX markings on the dipstick. Adding one
quart (0.95 liters) of oil when the reading is at the
MIN mark will result in a MAX reading on these
engines.
CAUTION!
Overfilling or underfilling will cause oil aeration
or loss of oil pressure. This could damage your
engine.
Change Engine Oil — All Engines
Road conditions and your kind of driving affects
the interval at which your oil should be changed.

(0°C).
