TIRES — GENERAL INFORMATION
Tire Pressure
Proper tire inflation pressure is essential to the
safe and satisfactory operation of your vehicle.
Four primary areas are affected by improper tire
pressure:
Safety
Fuel Economy
Tread Wear
Ride Comfort and Vehicle Stability
Safety Both underinflation and overinflation affect the
stability of the vehicle and can produce a feeling of
sluggish response or over responsiveness in the
steering.
NOTE:
Unequal tire pressures from side to side may
cause erratic and unpredictable steering
response.
Unequal tire pressure from side to side may
cause the vehicle to drift left or right.Fuel Economy
Underinflated tires will increase tire rolling
resistance resulting in higher fuel consumption.
Tread Wear
Improper cold tire inflation pressures can cause
abnormal wear patterns and reduced tread life,
resulting in the need for earlier tire replacement.
Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a comfortable
ride. Overinflation produces a jarring and
uncomfortable ride.
Tire Inflation Pressures
The proper cold tire inflation pressure is listed on
the driver's side B-pillar or rear edge of the driver's
side door.
At least once a month:
Check and adjust tire pressure with a good
quality pocket-type pressure gauge. Do not
make a visual judgment when determining
proper inflation. Tires may look properly inflated
even when they are underinflated.
Inspect tires for signs of tire wear or visible
damage.
WARNING!
Improperly inflated tires are dangerous and
can cause collisions.
Underinflation increases tire flexing and can
result in overheating and tire failure.
Overinflation reduces a tire's ability to cushion
shock. Objects on the road and chuckholes
can cause damage that result in tire failure.
Overinflated or underinflated tires can affect
vehicle handling and can fail suddenly,
resulting in loss of vehicle control.
Unequal tire pressures can cause steering
problems. You could lose control of your
vehicle.
Unequal tire pressures from one side of the
vehicle to the other can cause the vehicle to
drift to the right or left.
Always drive with each tire inflated to the
recommended cold tire inflation pressure.
WARNING!

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 half way).
NOTE:If in doubt about the correct tightness, have them
checked with a torque wrench by an 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 tightened.

FUEL REQUIREMENTS
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 a dealer immediately. Use of
gasoline with a lower than recommended octane
number can cause engine failure and may void 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.
3.6L 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
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.
5.7L 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
performance when using high-quality
unleaded gasoline having an octane 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.
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.

304TECHNICAL SPECIFICATIONS
REFORMULATED GASOLINE
Many areas of the country require the use of
cleaner burning gasoline referred to as
“reformulated gasoline”. Reformulated gasoline
contains oxygenates and are specifically blended
to reduce vehicle emissions and improve air
quality.
The use of reformulated gasoline is recommended.
Properly 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 Gasoline
contains a higher level of detergents to
further aide in minimizing engine and
fuel system deposits. When available,
the usage of TOP TIER Detergent Gasoline is
recommended. Visit
www.toptiergas.com for a list
of TOP TIER Detergent Gasoline retailers. 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 diaphragm materials.
GASOLINE/OXYGENATE BLENDS
Some fuel suppliers blend unleaded gasoline with
oxygenates such as ethanol.
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
the New Vehicle Limited Warranty.
DO NOT USE E-85 IN NON-FLEX FUEL
V
EHICLES
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 corro -
sion.
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).

CNG AND LP FUEL SYSTEM
M
ODIFICATIONS
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 components. Problems
that result from running CNG or LP are not the
responsibility of the manufacturer and may void
the New Vehicle Limited Warranty.
METHYLCYCLOPENTADIENYL
M
ANGANESE TRICARBONYL (MMT) IN
G
ASOLINE
MMT is a manganese-containing metallic additive
that is blended into some gasolines to increase
octane. Gasoline blended with MMT provides no
performance advantage beyond gasoline of the
same octane number without MMT. Gasoline
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
NOTE:Intentional tampering with the emissions control
system can result in civil penalties being assessed
against you.
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 performance and damage the emis -
sions control system.
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 autho -
rized dealer for service assistance.
The use of fuel additives, which are now being
sold as octane enhancers, is not recom -
mended. Most of these products contain high
concentrations of methanol. Fuel system
damage or vehicle performance problems
resulting from the use of such fuels or addi -
tives is not the responsibility of the manufac-
turer and may void or not be covered under
the New Vehicle Limited Warranty.
