CAUTION: If the Malfunction Indicator Lamp (MIL), Check Engine or Service Engine Soon light is flashing,
immediate service is required; see on-board diagnostics system section.
MATERIALS ADDED TO FUEL
All gasoline sold in the United States and Canada are required to contain effective detergent additives. Use of addi-
tional detergents or other additives is not needed under normal conditions.
FUEL SYSTEM CAUTIONS
CAUTION: Follow these guidelines to maintain your vehicle’s performance:
•
The use of leaded gas is prohibited by Federal law. Using leaded gasoline can impair engine performance,
damage the emission control system, and could result in loss of warranty coverage.
•
An out-of-tune engine, or certain fuel or ignition malfunctions, can cause the catalytic converter to overheat. If
you notice a pungent burning odor or some light smoke, your engine may be out of tune or malfunctioning and
may require immediate service. Contact your dealer for service assistance.
•
When pulling a heavy load or driving a fully loaded vehicle when the humidity is low and the temperature is
high, use a premium unleaded fuel to help prevent spark knock. If spark knock persists, lighten the load, or
engine piston damage may result.
•
The use of fuel additives which are now being sold as octane enhancers is not recommended. Most of these
products contain high concentrations of methanol. Fuel system damage or vehicle performance problems
resulting from the use of such fuels or additives is not the responsibility of DaimlerChrysler Corporation and
may not be covered under the new vehicle warranty.
NOTE: Intentional tampering with emissions control systems can result in civil penalties being assessed
against you.
ENGINE COOLANT
WARNING: ANTIFREEZE IS AN ETHYLENE GLYCOL BASE COOLANT AND IS HARMFUL IF SWALLOWED OR
INHALED. IF SWALLOWED, DRINK TWO GLASSES OF WATER AND INDUCE VOMITING. IF INHALED, MOVE
TO FRESH AIR AREA. SEEK MEDICAL ATTENTION IMMEDIATELY. DO NOT STORE IN OPEN OR UNMARKED
CONTAINERS. WASH SKIN AND CLOTHING THOROUGHLY AFTER COMING IN CONTACT WITH ETHYLENE
GLYCOL. KEEP OUT OF REACH OF CHILDREN. DISPOSE OF GLYCOL BASE COOLANT PROPERLY, CON-
TACT YOUR DEALER OR GOVERNMENT AGENCY FOR LOCATION OF COLLECTION CENTER IN YOUR
AREA.
WARNING: DO NOT OPEN A COOLING SYSTEM WHEN THE ENGINE IS AT OPERATING TEMPERATURE OR
HOT UNDER PRESSURE, PERSONAL INJURY CAN RESULT. AVOID RADIATOR COOLING FAN WHEN
ENGINE COMPARTMENT RELATED SERVICE IS PERFORMED, PERSONAL INJURY CAN RESULT.
CAUTION: Use of Propylene Glycol based coolants is not recommended, as they provide less freeze pro-
tection and less corrosion protection.
The cooling system is designed around the coolant. The coolant must accept heat from engine metal, in the cylinder
head area near the exhaust valves and engine block. Then coolant carries the heat to the radiator where the tube/
fin radiator can transfer the heat to the air.
The use of aluminum cylinder blocks, cylinder heads, and water pumps requires special corrosion protection.
Mopar
T
Antifreeze/Coolant, 5 Year/100,000 Mile Formula (MS-9769), or the equivalent ethylene glycol base coolant
with organic corrosion inhibitors (called HOAT, for Hybrid Organic Additive Technology) is recommended. This cool-
ant offers the best engine cooling without corrosion when mixed with 50% Ethylene Glycol and 50% distilled water
to obtain a freeze point of -37°C (-35°F). If it loses color or becomes contaminated, drain, flush, and replace with
fresh properly mixed coolant solution.
CAUTION: Do not use coolant additives that are claimed to improve engine cooling.
