CAUTION!
• Failure to properly maintain your vehicle or
perform repairs and service when necessary
could result in more costly repairs, damage
to other components or negatively impact
vehicle performance. Immediately have po-
tential malfunctions examined by an autho-
rized dealer or qualified repair center.
• Your vehicle has been built with improved
fluids that protect the performance and
durability of your vehicle and also allow
extended maintenance intervals. Do not
use chemical flushes in these components
as the chemicals can damage your engine,
transmission, power steering or air condi-
tioning. Such damage is not covered by
the New Vehicle Limited Warranty. If a
flush is needed because of component
malfunction, use only the specified fluid for
the flushing procedure.
Engine Oil – Gasoline Engines
Checking Oil Level
To assure proper lubrication of your vehicle's
engine, the engine oil must be maintained at the
correct level. The best time to check the engine
oil level is about five minutes after a fully
warmed up 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 level
range. Adding 1 U.S. Quart (0.95L) of oil when
the level is at the bottom of the SAFE range will
result in the level being at the top of the SAFE
range.
CAUTION!
Overfilling or underfilling the crankcase will
cause aeration or loss of oil pressure. This
could damage your engine.
Change Engine Oil
Refer to the "Maintenance Schedule" for the
proper maintenance intervals.
