CAUTION!
²If this light illuminates and the engine oil level is
not low, have your vehicle checked at an autho-
rized dealer.
²This warning light does not indicate the amount
of oil in the crankcase. This must be determined
by checking the oil level with the dipstick while
the engine is turned off.
Malfunction indicator light
(SERVICE ENGINE SOON)
This light is part of an onboard diagnostic
(OBD) system which monitors the emis-
sions, engine and automatic transaxle con-
trol systems. If a problem is detected in one
of these systems, this light may illuminate. Although
your vehicle will usually be drivable and not need
towing, have the system checked as soon as possible at an
authorized dealer.
This light will also illuminate for a few seconds, when the
ignition key is turned to the ªONº position. If it does not
go off after a few seconds, take the vehicle to an autho-
rized dealer.

ENGINE COOLANT
To check the coolant level
The coolant reserve system provides a quick visual
method for determining the coolant level. When the
engine is cold, the level of the coolant in the reserve tank
should be between the FULL and LOW marks. The
radiator normally remains completely full so there is no
need to remove the radiator cap except for checking the
coolant freeze point or replacing the antifreeze coolant.
To add coolant
Use DaimlerChrysler Genuine Coolant or an equivalent.
Genuine Coolant provides excellent protection against
corrosion and rust formation of all metals, including
aluminum, and prevents clogs in the radiator, heater,
cylinder head, engine block, etc.
If frequent coolant additions are required, or if the level
in the reserve tank does not drop when the engine cools,
the system should be pressure-tested for leaks. Take your
vehicle to an authorized dealer for inspection of the
cooling system.
CAUTION!
²Do not use alcohol or methanol anti-freeze or any
engine coolants mixed with alcohol or methanol
anti-freeze. The use of an improper anti-freeze can
cause corrosion of aluminum components.
²When additional coolant is needed to maintain
the proper level, a minimum of 50% concentration
of ethylene-glycol antifreeze in water should be
added to the reserve tank. Do not overfill. A
higher concentration (not to exceed 60%) should
be used if a lower freezing point is required. The
concentration level can be checked using instru-
ments available at automotive supply stores, or
can be done by your authorized dealer or service
station. Use only high quality ethylene-glycol
antifreeze coolant formulated to prevent corrosion
of all cooling system metals.
²Do not top off with water only. Water by itself
reduces the rust-protective and anti-freeze quali-
ties of the coolant and has a lower boiling point. It
can also cause damage to the cooling system if it
should freeze. Do not use tap water, as it may
cause corrosion and rust formation.
