IDENTIFICATION DATA
Vehicle Identification Number
The Vehicle Identification Number (VIN) is found on a
label located on the left front corner of the instrument panel
pad, visible from outside of the vehicle through the wind-
shield. This number also is stamped on the right front floor,
behind the right front seat. Move the right front seat
forward to allow better viewing of the stamped VIN. This
number also appears on the Automobile Information Dis-
closure Label affixed to a window on your vehicle. Save
this label for a convenient record of your vehicle identifi-
cation number and optional equipment.

450 TECHNICAL SPECIFICATIONS

NOTE:It is illegal to remove or alter the VIN.
BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic brake sys-
tems. If either of the two hydraulic systems loses normal
capability, the remaining system will still function. How-
ever, there will be some loss of overall braking effective-
ness. You may notice increased pedal travel during appli-
cation, greater pedal force required to slow or stop, and
potential activation of the Brake Warning Light. In the event power assist is lost for any reason (i.e.,
repeated brake applications with the engine off) the brakes
will still function. However, the effort required to brake the
vehicle will be much greater than that required with the
power system operating.
NOTE:
Due to the performance nature of our brake sys-
tems, some noise is to be expected.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to ensure that
the wheel is properly mounted to the vehicle. Any time a
wheel has been removed and reinstalled on the vehicle, the
lug nuts/bolts should be torqued using a properly cali-
brated torque wrench using a high quality six sided (hex)
deep wall socket.

TECHNICAL SPECIFICATIONS 451

Inspect the wheel mounting surface prior to mounting the
tire and remove any corrosion or loose particles.
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 half
way).
NOTE:If in doubt about the correct tightness, have them
checked with a torque wrench by your authorized dealer or
service station. 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.
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.

FUEL REQUIREMENTS
6.4L Engine
Do not use E-85 flex fuel or ethanol blends greater than
15% in this engine.This engine is designed to meet all emis-
sion regulations, provide optimal fuel
economy and performance when using
high-quality unleaded “Premium” gaso-
line having a posted octane number of
91 as specified by the (R+M)/2 method.
The use of 91 or higher octane “Pre-
mium” gasoline is required for in this engine.
While operating on gasoline with the required octane
number, 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 immedi-
ately. Use of gasoline with a lower than recommended
octane number 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 consider-
ing service for the vehicle.
Reformulated Gasoline
Many areas of the country require the use of cleaner burning
gasoline referred to as “Reformulated Gasoline”. Reformu-
lated gasoline contains oxygenates and are specifically
blended to reduce vehicle emissions and improve air quality.
The use of reformulated gasoline is recommended. Prop-
erly blended reformulated gasoline will provide improved
performance and durability of engine and fuel system
components.
Materials Added To Fuel
Besides using unleaded gasoline with the proper octane
rating, gasolines that contain detergents, corrosion and
stability additives are recommended. Using gasolines that
have these additives will help improve fuel economy,
reduce emissions, and maintain vehicle performance.
Designated TOP TIER Detergent Gaso-
line contains a higher level of detergents
to further aide in minimizing engine
and fuel system deposits. When avail-
able, the usage of TOP TIER Detergent
gasoline is recommended. Visit
www.toptiergas.com for a list of TOP
TIER Detergent Gasoline Retailers.

TECHNICAL SPECIFICATIONS 453

Indiscriminate use of fuel system cleaning agents should be
avoided. Many of these materials intended for gum and
varnish removal may contain active solvents or similar
ingredients. These can harm fuel system gasket and dia-
phragm materials.
Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline with oxygen-
ates such as ethanol.
CAUTION!
DO NOT use E-85, gasoline containing methanol, or
gasoline containing more than 15% ethanol (E-15). Use
of these blends may result in starting and drivability
problems, damage critical fuel system components,
cause emissions to exceed the applicable standard,
and/or cause the “Malfunction Indicator Light” to
illuminate. Please observe pump labels as they should
clearly communicate if a fuel contains greater than 15%
ethanol (E-15).
Problems that result from using gasoline containing more than
15% ethanol (E-15) or gasoline containing methanol are not the
responsibility of the manufacturer and may void or not be
covered under New Vehicle Limited Warranty.
Do Not Use E-85 In Non-Flex Fuel Vehicles
Non-Flex Fuel Vehicles (FFV) are compatible with gasoline
containing up to 15% ethanol (E-15). Use of gasoline with
higher ethanol content may void the New Vehicle Limited
Warranty.
If a Non-FFV vehicle is inadvertently fueled with E-85 fuel,
the engine will have some or all of these symptoms:
•Operate in a lean mode.
• OBD II “Malfunction Indicator Light” on.
• Poor engine performance.
• Poor cold start and cold drivability.
• Increased risk for fuel system component corrosion.
CNG And LP Fuel System Modifications
Modifications that allow the engine to run on compressed
natural gas (CNG) or liquid propane (LP) may result in
damage to the engine, emissions, and fuel system compo-
nents. Problems that result from running CNG or LP are
not the responsibility of the manufacturer and may void or
not be covered under the New Vehicle Limited Warranty.
454 TECHNICAL SPECIFICATIONS

MMT In Gasoline
Methylcyclopentadienyl Manganese Tricarbonyl (MMT) is
a manganese-containing metallic additive that is blended
into some gasoline to increase octane. Gasoline blended
with MMT provides no performance advantage beyond
gasoline of the same octane number without MMT. Gaso-
line blended with MMT reduces spark plug life and
reduces emissions system performance in some vehicles.
The manufacturer recommends that gasoline without
MMT be used in your vehicle. The MMT content of
gasoline may not be indicated on the gasoline pump;
therefore, you should ask your gasoline retailer whether
the gasoline contains MMT. MMT is prohibited in Federal
and California reformulated gasoline.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle’s
performance:
•The use of leaded gasoline is prohibited by Federal
law. Using leaded gasoline can impair engine perfor-
mance and damage the emissions control system.
(Continued)
CAUTION! (Continued)
•An out-of-tune engine or certain fuel or ignition
malfunctions can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune or
malfunctioning and may require immediate service.
Contact an authorized dealer for service assistance.
• The use of fuel additives, which are now being sold
as octane enhancers, is not recommended. Most of
these products contain high concentrations of metha-
nol. Fuel system damage or vehicle performance
problems resulting from the use of such fuels or
additives is not the responsibility of the manufac-
turer and may void or not be covered under the New
Vehicle Limited Warranty.
NOTE: Intentional tampering with the emissions control
system can result in civil penalties being assessed against
you.
