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 re-
moved and reinstalled on the vehicle, the lug
nuts/bolts should be torqued using a properly
calibrated torque wrench using a high quality
six sided (hex) deep wall socket.

**Use only your authorized dealer recom-
mended 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.
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.

the vehicle from resting on the ground with
the body or chassis after touching the wedge
with its lowest and most projecting parts
(usually the underbody), because this would
highly reduce wheel grip.
The wheels, without a suitable grip to the
ground, will not have sufficient hold to move
the vehicle, and will surge.
The higher the ground clearance, the wider
the breakover angle. Always bear in mind that
the higher the ground clearance, the lower
the stability, due to a higher center of gravity
which reduces the side rollover angle.WHEELS
Refer to the Tire Placard label located on the
door sill of the vehicle or to the Registration
Document for the tire size and pressure.
Refer to “Tires” in “Servicing and Mainte-
nance” for further information.

CAUTION!
Do not load your vehicle any heavier than
the GVWR or the maximum front and rear
GAWR. If you do, parts on your vehicle can
break, or it can change the way your ve-
hicle handles. This could cause you to lose
control. Also overloading can shorten the
life of your vehicle. Never exceed the maxi-
mum combined vehicle load value: the
maximum towable load is only allowed if it
does not exceed the maximum combined
vehicle load.
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

Reformulated Gasoline
Many areas of the country require the use of
cleaner burning gasoline referred to as “Re-
formulated Gasoline”. Reformulated gaso-
line contains oxygenates and are specifically
blended to reduce vehicle emissions and im-
prove air quality.
The use of reformulated gasoline is recom-
mended. Properly blended reformulated
gasoline will provide improved performance
and durability of engine and fuel system
components.
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.
Materials Added To Fuel
Indiscriminate use of fuel system cleaning
agents should be avoided. Many of these
materials intended for gum and varnish re-
moval may contain active solvents or similar
ingredients. These can harm fuel system gas-
ket and diaphragm materials.
Fuel Icon Identification Compliant To
EN16942
The following symbols make it easier to rec-
ognize the correct type of fuel to be used on
your vehicle. Before proceeding with the sup-
ply, check the symbols placed inside the fuel
filler flap (if present) and compare them with
the symbol on the fuel pump (if present).

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.TECHNICAL SPECIFICATIONS
