MAINTENANCE PROCEDURES
The pages that follow contain therequiredmaintenance
services determined by the engineers who designed your
vehicle.
Besides the maintenance items for which there are fixed
maintenance intervals, there are other items that should
operate satisfactorily without periodic maintenance.
However, if a malfunction of these items does occur, it
could adversely affect the engine or vehicle performance.
These items should be inspected if a malfunction is
observed or suspected.
ENGINE OIL
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 five
minutes after a fully warmed engine is shut off or before
starting the engine after it has sat overnight.

recommends engine oils that are API certified and meet
the requirements of DaimlerChrysler Material Standard
MS-6395.
American Petroleum Institute (API) Engine Oil
Identification Symbol
This symbol means that the oil has
been certified by the American
Petroleum Institute (API). The
manufacturer only recommends
API Certified engine oils.
Engine Oil Viscosity (SAE Grade) Ð 3.3L & 3.8L
Gasoline Engines
SAE 5W-20 engine oil is recommended for all operating
temperatures. This engine oil improves low temperaturestarting and vehicle fuel economy. Your engine oil filler
cap also shows the recommended engine oil viscosity for
your vehicle.
For information on engine oil filler cap location, refer to
the Engine Compartment illustration in this section.
Lubricants which do not have both, the engine oil certi-
fication mark and the correct SAE viscosity grade num-
ber should not be used.
Engine Oil Viscosity (SAE Grade) Ð 4.0 Liter
Engines
SAE 10W-30engine oil is preferred for all operating
temperatures. The engine oil filler cap also shows the
recommended engine oil viscosity for your vehicle.
Lubricants which DO NOT have both, the engine oil
certification mark and the correct SAE viscosity grade
number should not be used.

CATALYTIC CONVERTER
The catalytic converter requires the use of unleaded fuel
only. Leaded gasoline will destroy the effectiveness of the
catalyst as an emission control device.
Under normal operating conditions, the catalytic con-
verter will not require maintenance. However, it is im-
portant to keep the engine properly tuned to assure
proper catalyst operation and prevent possible catalyst
damage.CAUTION!
Damage to the catalytic converter can result if your
vehicle is not kept in proper operating condition. In
the event of engine malfunction, particularly involv-
ing engine misfire or other apparent loss of perfor-
mance, have your vehicle serviced promptly. Contin-
ued operation of your vehicle with a severe
malfunction could cause the converter to overheat,
resulting in possible damage to the converter and the
vehicle.
NOTE:Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.

²Do not change the thermostat for summer or winter
operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory coolant performance, poor gas
mileage, and increased emissions.
HOSES AND VACUUM/VAPOR HARNESSES
Inspect surfaces of hoses and nylon tubing for evidence
of heat and mechanical damage. Hard or soft spots,
brittle rubber, cracking, tears, cuts, abrasions, and exces-
sive swelling indicate deterioration of the rubber.
Pay particular attention to those hoses nearest to high
heat sources such as the exhaust manifold. Inspect hose
routing to be sure hoses do not come in contact with any
heat source or moving component which may cause heat
damage or mechanical wear.
Ensure nylon tubing in these areas has not melted or
collapsed.Inspect all hose connections such as clamps and cou-
plings to make sure they are secure and no leaks are
present.
Components should be replaced immediately if there is
any evidence of wear or damage that could cause failure.FUEL SYSTEM CONNECTIONS
The Electronic Fuel Injection high-pressure fuel system's
hoses and quick connect fittings have unique material
characteristics that provide adequate sealing and resist
attack by deteriorated gasoline.
You are urged to use only the manufacture specified
hoses with quick connect fittings, or their equivalent in
material and specification, in any fuel system servicing. It
is mandatory to replace any damaged hoses or quick
connect fittings that have been removed during service.
Care should be taken in installing quick connect fittings
to ensure they are properly installed and fully connected.
See your authorized dealer for service.
