**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.
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).
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 seated against the wheel.

FUEL REQUIREMENTS
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
excellent fuel economy and
performance when using high-quality
unleaded “Regular” gasoline having an
octane rating of 87 as specified by the
(R+M)/2 method. The use of higher octane
“Premium” gasoline will not provide any benefit
over “Regular” gasoline in these engines.
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 an authorized 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.
5.7L ENGINE (WITH AUTOMATIC
T
RANSMISSION)
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 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 an authorized 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.
5.7L ENGINE (WITH MANUAL
T
RANSMISSION)
Do not use E-85 flex fuel or ethanol blends
greater than 15% in this engine.
This engine is designed to meet all
emission regulations, provide optimal
fuel economy and performance when
using high-quality unleaded
“Premium” gasoline having a posted
octane number of 91 as specified by the
(R+M)/2 method. The use of 91 or higher
octane “Premium” gasoline is required for
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 an authorized dealer
immediately. 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.

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.

296TECHNICAL 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. 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 CAUTIONSNOTE:
Intentional tampering with the emissions
control system can result in civil penalties being
assessed against you.
CARBON MONOXIDE WARNINGS
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 emissions control system.
An out-of-tune engine or certain fuel or igni -
tion 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 malfunc -
tioning 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 methanol.
Fuel system damage or vehicle perfor -
mance problems resulting from the use of
such fuels or additives is not the responsi -
bility of the manufacturer and may void or
not be covered under the New Vehicle
Limited Warranty.
WARNING!
Carbon monoxide (CO) in exhaust gases is
deadly. Follow the precautions below to
prevent carbon monoxide poisoning:
Do not inhale exhaust gases. They contain
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 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.
