548 TECHNICAL SPECIFICATIONS
Tighten the lug nuts/bolts in a star pattern until each nut/
bolt has been tightened twice. Ensure that the socket is fully
engaged on the lug nut/bolt (do not insert it halfway).
After 25 miles (40 km), check the lug nut/bolt torque to be
sure that all the lug nuts/bolts are properly seated against
the wheel.Four, Five, And Six Lug Nuts/Bolts Torque Pattern
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.

INSTALLATION OF RADIO TRANSMITTING
EQUIPMENT
Special design considerations are incorporated into this
vehicle’s electronic system to provide immunity to radio
frequency signals. Mobile two-way radios and telephone
equipment must be installed properly by trained person-
nel. The following must be observed during installation.
The positive power connection should be made
directly to the battery and fused as close to the battery as
possible. The negative power connection should be made
to body sheet metal adjacent to the negative battery
connection. This connection should not be fused.
Antennas for two-way radios should be mounted on
the roof or the rear area of the vehicle. Care should be
used in mounting antennas with magnet bases. Magnets
may affect the accuracy or operation of the compass on
vehicles so equipped.
The antenna cable should be as short as practical and
routed away from the vehicle wiring when possible. Use
only fully shielded coaxial cable.
Carefully match the antenna and cable to the radio to
ensure a low Standing Wave Ratio (SWR). Mobile radio equipment with output power greater than
normal may require special precautions.
All installations should be checked for possible

interference between the communications equipment
and the vehicle’s electronic systems.
Operating, servicing and maintain -
ing a passenger vehicle or off-highway
motor vehicle can expose you to chemicals
including engine exhaust, carbon monox -
ide, phthalates, and lead, which are known
to the State of California to cause cancer and
birth defects or other reproductive harm.
To minimize exposure, avoid breathing
exhaust, do not idle the engine except as
necessary, service your vehicle in a
well-ventilated area and wear gloves or
wash your hands frequently when servicing
your vehicle. For more information go to
www.P65Warnings.ca.gov/passenger-vehicle .
