TECHNICAL SPECIFICATIONS
IDENTIFICATION DATA
Vehicle Identification Number
The Vehicle Identification Number (VIN) is found
on the left front corner of the instrument panel,
visible through the windshield. This number
also appears on the vehicle frame etched on
right hand center rail, as well as the Automobile
Information Disclosure Label affixed to a
window on your vehicle, the vehicle registration
and title.
Vehicle Identification Number
NOTE:
It is illegal to remove or alter the VIN.BRAKE SYSTEM
If power assist is lost for any reason (for
example, repeated brake applications with the
engine off), the brakes will still function.
However, you will experience a substantial
increase in braking effort to stop the vehicle.
If either the front or rear hydraulic system loses
normal braking capability, the remaining
system will still function with some loss of
overall braking effectiveness. This will be
evident by increased pedal travel during appli
-
cation, greater pedal force required to slow or
stop, and activation of the “Brake Warning
Light” and/or the “ABS Warning Light” during
brake use.
Hydraulic Brake Assist — If Equipped
The brake system power assist is provided by a
hydro-boost unit which shares fluid with the
power steering system. You may experience
some clicking or hissing noises from the
hydro-boost system during hard braking condi -
tions.
NOTE:
Under cold temperatures, pedal effort will be
higher than normal until the power steering fluid
reaches operating temperature.
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.

Torque Specifications
**Use only authorized dealer recommended
lug nuts/bolts and clean or remove any dirt or
oil before tightening.
Inspect the wheel mounting surface prior to
mounting the tire and remove any corrosion or
loose particles.
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 hex and the washer.
Ensure that the socket is fully engaged on the
lug nut/bolt (do not insert it half way).

Oil Interface Location

Do not oil wheel studs. For chrome wheels, do
not substitute with chrome plated wheel nuts.

Wheel Mounting Surface
Retighten the wheel nuts in the same sequence
to the torques listed in the table. Go through the
sequence a second time to verify that specific
torque has been achieved. Retighten to specifi
-
cations after 25 miles (40 km) and check the
lug nut/bolt torque to be sure that all the lug
nuts/bolts are properly seated against the
wheel.

8/10 Lug Nuts/Bolts Torque Patterns

It is recommended that wheel stud nuts be kept
torqued to specifications at all times. Torque
wheel stud nuts to specifications at each lubri -
cation interval.

TECHNICAL SPECIFICATIONS399
All wheel nuts should be tightened occasionally
to eliminate the possibility of wheel studs being
sheared or the bolt holes in the wheels
becoming elongated. This is especially
important during the first few hundred miles/
kilometers of operation to allow the wheel nuts
to become properly set. All wheel nuts should
first be firmly seated against the wheel. The
wheel nuts should then be tightened to recom -
mended torque. Tighten the wheel nuts to final
torque in increments. Progress around the bolt
circle, tightening the wheel nut opposite to the
wheel nut just previously tightened until final
torque is achieved.FUEL REQUIREMENTS — GAS ENGINE
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
emissions regulations and provide
satisfactory fuel economy and perfor -
mance 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 perfor -
mance 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 dealer immediately. Use of
gasoline 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.
Reformulated Gasoline
Many areas of the country require the use of
cleaner burning gasoline referred to as “Refor
-
mulated Gasoline”. Reformulated gasoline
contains oxygenates and are specifically
blended to reduce vehicle emissions and
improve air quality.
The use of reformulated gasoline is recom -
mended. Properly blended reformulated gaso -
line will provide improved performance and
durability of engine and fuel system compo -
nents.
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.
