CAUTION!
Overfilling or underfilling will cause oil aeration or
loss of oil pressure. This could damage your engine.
Checking Oil Level — 5.7L Engine
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 overnight.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Maintain
the oil level in the “SAFE” range. Adding 1.0 quart (1.0L)
of oil when the reading is at the bottom of the “SAFE”
range will result in an oil level at the top of the “SAFE”
range on these engines.

American Petroleum Institute (API) Engine Oil
Identification Symbol
This symbol means that the oil has
been certified by the American
Petroleum Institute (API). The
manufacture only recommends
API Certified engine oils.
Engine Oil Viscosity (SAE Grade) — 2.7L and 5.7L
Engines
SAE 5W-20 engine oil is recommended for all operating
temperatures. This engine oil improves low temperature
starting and vehicle fuel economy.
The engine oil filler cap also shows the recommended
engine oil viscosity for your engine. For information on
engine oil filler cap location, refer to the “Engine Com-
partment” illustration in this section.
NOTE:Vehicles equipped with a 5.7L engine must use
SAE 5W-20 oil. Failure to do so may result in improper
operation of the Multiple Displacement System (MDS).
Refer to “Multi Displacement System” under “Starting
and Operating” for details.
In areas where these grades are not generally available,
higher SAE grades may be used. Lubricants that have
both an SAE grade number and the API Certification
Symbol or ACEA category shown on the container
should be used.
Lubricants that do not have both the engine oil certifica-
tion mark and the correct SAE viscosity grade number
should not be used.

Engine Air Cleaner Filter
For normal driving conditions, inspect and replace the
engine air cleaner filter at the intervals shown on Sched-
ule “A.” For vehicles driven frequently in dusty or under
severe conditions, inspect and replace the engine air
cleaner filter at the intervals shown on Schedule “B.”
WARNING!
The air induction system (air cleaner, hoses, etc) can
provide a measure of protection in the case of engine
backfire. Do not remove the air induction system (air
cleaner, hoses, etc) unless such removal is necessary
for repair or maintenance. Make sure that no one is
near the engine compartment before starting the
vehicle with the air induction system (air cleaner,
hoses, etc) removed. Failure to do so can result in
serious personal injury.
Fuel Filter
A plugged fuel filter can cause stalling, limit the speed at
which a vehicle can be driven or cause hard starting.
Should an excessive amount of dirt accumulate in the
fuel tank, filter replacement may be necessary. See your
local dealer for service.
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.

Insure 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
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 insure they are properly installed and fully connected.
See your authorized dealer for service.
Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically.
Suggested service intervals can be found in the “Mainte-
nance Schedule” in this manual.
WARNING!
Riding the brakes can lead to brake failure and
possibly an accident. Driving with your foot resting
or riding on the brake pedal can result in abnormally
high brake temperatures, excessive lining wear, and
possible brake damage. You wouldn’t have your full
braking capacity in an emergency.
Brake and Power Steering Hoses
When the vehicle is serviced for scheduled maintenance,
inspect surface of hoses and nylon tubing for evidence of
heat and mechanical damage. Hard and brittle rubber,
cracking, tears, cuts, abrasion, and excessive swelling
indicate deterioration of the rubber. Particular attention
should be made to examining those hose surfaces nearest
to high heat sources, such as the exhaust manifold.

At Each Stop for Fuel
•
Check the engine oil level about 5 minutes after a fully
warmed engine is shut off. Checking the oil level while
the vehicle is on level ground will improve the accu-
racy of the oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.
•Check the windshield washer solvent and add if
required.
Once a Month
•
Check tire pressure and look for unusual wear or
damage.
•Inspect the battery, and clean, and tighten the termi-
nals as required.
•Check the fluid levels of coolant reservoir and brake
master cylinder, and add as needed.
•Check all lights and all other electrical items for correct
operation.
•Check rubber seals on each side of the radiator for
proper fit.
At Each Oil Change
•
Change the engine oil filter.
•Inspect the exhaust system.
•Inspect the brake hoses.
•Inspect the CV joints and front and rear suspension
components.
•Check the coolant level, hoses, and clamps.
