Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts and
cracks. Inspect sidewalls for cuts, cracks, and bulges. Check
the wheel bolts for tightness. Check the tires (including
spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight parking for
fuel, coolant, oil, or other fluid leaks. Also, if gasoline fumes
are detected or if fuel, or brake fluid leaks are suspected, the
cause should be located and corrected immediately.

FUEL REQUIREMENTS
3.6L Engine
Do not use E-85 flex fuel or ethanol blends greater than 15%
in this engine. These engines are designed to meet all emissions
regulations and provide optimum fuel economy and
performance when using high quality unleaded
“Regular” gasoline having a posted octane number of 87 as
specified by the (R+M)/2 method. The use of higher octane
“Premium” gasoline is not required, as it will not provide
any benefit over “Regular” gasoline in these engines.
WARNING!
To avoid the risk of forcing the vehicle off the jack, do
not tighten the lug nuts/bolts fully until the vehicle has
been lowered. Failure to follow this warning may result
in personal injury.
