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 fully
until the vehicle has been lowered. Failure
to follow this warning may result in per-
sonal injury.
FUEL REQUIREMENTS —
GASOLINE ENGINES
3.6L Engine
These engines are designed to meet all emis-
sions regulations and provide excellent fuel
economy and performance when using high-
quality unleaded gasoline with a minimum
Research Octane Number (RON) of 91.
Light spark knock at low engine speeds is not
harmful to your engine. However, continued
heavy spark knock at high speeds can cause
damage, and immediate service is required.
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 may help improve fuel
economy, reduce emissions, and maintain
vehicle performance.
Poor quality gasoline can cause problems
such as hard starting, stalling and stumble. If
you experience these problems, try another
brand of gasoline before considering service
for the vehicle.
5.7L Engine
Theses engines are designed to meet all
emissions regulations and provide satisfac-
tory fuel economy and performance when
using high-quality unleaded gasoline having
an Research Octane Number (RON) of 91 to
95. The manufacturer recommends the use
of a 95 Research Octane Number for opti-
mum performance.
Light spark knock at low engine speeds is not
harmful to your engine. However, continued
heavy spark knock at high speeds can cause
damage, and immediate service is required.
Poor quality gasoline can cause problems
such as hard starting, stalling, and hesita-tions. If you experience these symptoms, try
another brand of gasoline before considering
service for the vehicle.
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 may help improve fuel
economy, reduce emissions, and maintain
vehicle performance.
Poor quality gasoline can cause problems
such as hard starting, stalling and stumble. If
you experience these problems, try another
brand of gasoline before considering service
for the vehicle.
6.2L/6.4L Engine
Your vehicle is designed to meet all emissions
regulations and provide excellent fuel
economy and performance when using high-
quality unleaded gasoline having an Re-
search Octane Number (RON) of 98 or
higher. The manufacturer recommends the
use of 98 Research Octane Number (RON) or
higher for optimum performance.Light spark knock at low engine speeds is not
harmful to your engine. However, continued
heavy spark knock at high speeds can cause
damage and immediate service is required.
Poor quality gasoline can cause problems
such as hard starting, stalling, and hesita-
tions. If you experience these symptoms, try
another brand of gasoline before considering
service for the vehicle.
Methanol
(Methyl) is used in a variety of concentrations
when blended with unleaded gasoline. You
may find fuels containing 3% or more metha-
nol along with other alcohols called cosol-
vents. Problems that result from using
methanol/gasoline are not the responsibility
of the manufacturer. While MTBE is an oxy-
genate made from Methanol, it does not have
the negative effects of Methanol.
WARNING!
Do not use gasolines containing Methanol.
Use of these blends may result in starting
and drivability problems and may damage
critical fuel system components.

Carbon Monoxide Warnings
WARNING!
Carbon monoxide (CO) in exhaust gases is
deadly. Follow the precautions below to
prevent carbon monoxide poisoning:
• Do not inhale exhaust gases. They con-
tain carbon monoxide, a colorless and
odorless gas, which can kill. Never run
the engine in a closed area, such as a
garage, and never sit in a parked vehicle
with the engine running for an extended
period. If the vehicle is stopped in an
open area with the engine running for
WARNING!
more than a short period, adjust the
ventilation system to force fresh, outside
air into the vehicle.
• Guard against carbon monoxide with
proper maintenance. Have the exhaust
system inspected every time the vehicle
is raised. Have any abnormal conditions
repaired promptly. Until repaired, drive
with all side windows fully open.
FUEL REQUIREMENTS –
DIESEL ENGINE
Use good quality diesel fuel from a reputable
supplier. If the outside temperature is very
low, the diesel fuel thickens due to the for-
mation of paraffin clots with consequent de-
fective operation of the fuel supply system. In
order to avoid these problems different types
of fuel are distributed according to the sea-
son: summer type, winter type and arctic type
(cold/mountain areas).This vehicle must only
use premium diesel fuel that meets the require-
ments of EN 590. Biodiesel blends up to 7% that
meet EN 590 may also be used.
275

WARNING!
Do not use alcohol or gasoline as a fuel
blending agent. They can be unstable un-
der certain conditions and hazardous or
explosive when mixed with diesel fuel.
Diesel fuel is seldom completely free of wa-
ter. To prevent fuel system trouble, drain the
accumulated water from the fuel/water sepa-
rator using the fuel/water separator drain pro-
vided on the fuel filter housing. If you buygood quality fuel and follow the cold weather
advice above, fuel conditioners should not be
required in your vehicle. If available in your
area, a high cetane “premium” diesel fuel
may offer improved cold-starting and
warm-up performance.
CAUTION!
If the “Water in Fuel Indicator Light” re-
mains on, DO NOT START engine before
