SAFETY 289
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.
• ALWAYS make sure objects cannot fall or slide into the
driver’s side floor area when the vehicle is moving.
Objects can become trapped under accelerator, brake,
or clutch pedals and could cause a loss of vehicle
control.
• NEVER place any objects under the floor mat (e.g., towels, keys, etc.). These objects could change the posi -
tion of the floor mat and may cause interference with
the accelerator, brake, or clutch pedals.
• If the vehicle carpet has been removed and re-installed, always properly attach carpet to the floor and check the
floor mat fasteners are secure to the vehicle carpet.
Fully depress each pedal to check for interference with
the accelerator, brake, or clutch pedals then re-install
the floor mats.
• It is recommended to only use mild soap and water to clean your floor mats. After cleaning, always check
your floor mat has been properly installed and is
secured to your vehicle using the floor mat fasteners by
lightly pulling mat.

NOTE:
Dual wheels are flat mounted, center piloted. The lug nuts
are a two-piece assembly. When the tires are being rotated or
replaced, clean these lug nuts and add two drops of oil at the
interface between the lug nut/bolt and the washer. Do not
oil wheel studs.
Two-Piece Lug Nut
Inspect the wheel mounting surface prior to mounting the
tire and remove any corrosion or loose particles.
Wheel Mounting Surface
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).

TECHNICAL SPECIFICATIONS 567
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 And Five Lug Nuts/Bolts Torque PatternFUEL REQUIREMENTS
6.4L Engine
Do not use E-85 flex fuel or ethanol blends greater than 15%
in this engine. This engines is designed to meet all emissions regu -
lations and provide satisfactory fuel economy and
performance when using high quality unleaded
gasoline having a posted octane number range of 87 to 89 as
specified by the (R+M)/2 method. The use of 89 octane
“Plus” gasoline is recommended for optimum performance
and fuel economy.
While operating on gasoline with an octane number of 87,
hearing a light knocking sound from the engine is not a cause
for concern. However, if the engine is heard making a heavy
knocking sound, see your dealer immediately. Use of gaso -
line with an octane number lower than 87 can cause engine
failure and may void or not be covered by the New Vehicle
Limited Warranty.
Poor quality gasoline can cause problems such as hard
starting, stalling, and hesitations. If you experience these
symptoms, try another brand of gasoline before considering
service for the vehicle.
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.8
