WARNING!
Do not attempt jump starting if the battery
is frozen. It could rupture or explode and
cause personal injury.
CAUTION!
Do not use a portable battery booster pack
or any other booster source with a system
voltage greater than 12 Volts or damage to
the battery, starter motor, alternator or
electrical system may occur.
NOTE:
When using a portable battery booster pack,

tions and precautions.
Preparations For Jump Start
The battery in your vehicle is located under
the passenger's front seat. There are remote
terminals located under the hood to assist in
jump starting.WARNING!
• Take care to avoid the radiator cooling
fan whenever the hood is raised. It can
start anytime the ignition switch is ON.
You can be injured by moving fan
blades.
WARNING!
• Remove any metal jewelry such as rings,
watch bands and bracelets that could
make an inadvertent electrical contact.
You could be seriously injured.
• Batteries contain sulfuric acid that can
burn your skin or eyes and generate
hydrogen gas which is flammable and
explosive. Keep open flames or sparks
away from the battery.
NOTE:
Be sure that the disconnected cable ends do
not touch each other, or either vehicle, until
properly connected for jump starting.
1. Apply the parking brake, shift the auto-
matic transmission into PARK and turn
the ignition OFF.
2. Turn off the heater, radio, and all unnec-
essary electrical accessories.
3. Remove the protective cover over the re-
mote positive(+)battery post. Pull up-
ward on the cover to remove it.

4. If using another vehicle to jump start the
battery, park the vehicle within the jumper
cables reach, apply the parking brake and
make sure the ignition is OFF.
WARNING!
Do not allow vehicles to touch each other
as this could establish a ground connec-
tion and personal injury could result.
Jump Starting Procedure
WARNING!
Failure to follow this jump starting proce-
dure could result in personal injury or
property damage due to battery explosion.
CAUTION!
Failure to follow these procedures could
result in damage to the charging system of
the booster vehicle or the discharged ve-
hicle.NOTE:
Make sure at all times that unused ends of
jumper cables are not contacting each other
or either vehicle while making connections.
Connecting The Jumper Cables
1. Connect the positive(+)end of the jumper
cable to the remote positive(+)post of the
discharged vehicle.
2. Connect the opposite end of the positive
(+)jumper cable to the positive(+)post of
the booster battery.

WARNING!
personal injury. Only use the specific
ground point, do not use any other exposed
metal parts.
5. Start the engine in the vehicle that has the
booster battery, let the engine idle a few
minutes, and then start the engine in the
vehicle with the discharged battery.
CAUTION!
Do not run the booster vehicle engine
above 2,000 rpm since it provides no
charging benefit, wastes fuel, and can
damage booster vehicle engine.

WARNING!
boiling point. This may cause it to boil
unexpectedly during hard or prolonged
braking, resulting in sudden brake fail-
ure. This could result in a collision.
• Overfilling the brake fluid reservoir can
result in spilling brake fluid on hot en-
gine parts, causing the brake fluid to
catch fire. Brake fluid can also damage
painted and vinyl surfaces, care should
be taken to avoid its contact with these
surfaces.
• Do not allow petroleum based fluid to
contaminate the brake fluid. Brake seal
components could be damaged, causing
partial or complete brake failure. This
could result in a collision.
Automatic Transmission
Fluid Level Check
The fluid level is preset at the factory and
does not require adjustment under normal
operating conditions. Routine fluid level
checks are not required; therefore the trans-
mission has no dipstick. An authorized dealercan check your transmission fluid level using
special service tools. If you notice fluid leak-
age or transmission malfunction, visit an au-
thorized dealer immediately to have the
transmission fluid level checked. Operating
the vehicle with an improper fluid level can
cause severe transmission damage.
CAUTION!
If a transmission fluid leak occurs, visit an
authorized dealer immediately. Severe
transmission damage may occur. An au-
thorized dealer has the proper tools to
adjust the fluid level accurately.
Maintenance-Free Battery
Your vehicle is equipped with a maintenance-
free battery. You will never have to add water,
nor is periodic maintenance required.
WARNING!
• Using the battery with low fluid will
irreparably damage the battery and may
cause an explosion.
WARNING!
• When performing any operation on the
battery or near it, always protect your
eyes with special goggles.
• Batteries contain substances which are
very dangerous for the environment. For
battery replacement, contact an autho-
rized dealership.
• Battery fluid is a corrosive acid solution
and can burn or even blind you. Do not
allow battery fluid to contact your eyes,
skin, or clothing. Do not lean over a
battery when attaching clamps. If acid
splashes in eyes or on skin, flush the
area immediately with large amounts of
water. Refer to “Jump Starting Proce-
dure” in “In Case Of Emergency” for
further information.
• Battery gas is flammable and explosive.
Keep flame or sparks away from the
battery. Do not use a booster battery or
any other booster source with an output
greater than 12 Volts. Do not allow cable
clamps to touch each other.
SERVICING AND MAINTENANCE

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

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.
Ethanol
The manufacturer recommends that your ve-
hicle be operated on fuel containing no more
than 15% ethanol. Purchasing your fuel from
a reputable supplier may reduce the risk of
exceeding this 15% limit and/or of receiving
fuel with abnormal properties. It should also
be noted that an increase in fuel consump-
tion should be expected when using ethanol-
blended fuels, due to the lower energy con-
tent of ethanol. Problems that result from
using methanol/gasoline or E-85 ethanol
blends are not the responsibility of the
manufacturer.
CAUTION!
Use of fuel with Ethanol content higher
than 15% may result in engine malfunc-
tion, starting and operating difficulties,
and materials degradation. These adverse
effects could result in permanent damage
to your vehicle.
