Electronic Stability Control
In full on mode the TCS system enhances directional
control and stability of the vehicle under various driving
conditions. The ESC corrects for oversteering and under-
steering the vehicle by applying the brake of the appropri-
ate wheel. Engine power may also be reduced to assist in
counteracting the condition of oversteer or understeer and
help the vehicle maintain the desired path.
In full on mode ESC utilizes sensors in the vehicle to
determine the path that the driver intends to steer the
vehicle and compares it to the actual path of the vehicle.
When the actual path does not match the intended path,
the ESC applies the brake of the appropriate wheel to assist
in counteracting the condition of oversteer or understeer.
•Oversteer – when the vehicle is turning more than
appropriate for the steering wheel position.
• Understeer – when the vehicle is turning less than
appropriate for the steering wheel position.
WARNING!
The Electronic Stability Control System (ESC) cannot
prevent the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded by
prevailing road conditions. ESC cannot prevent all
accidents, including those resulting from excessive
speed in turns, driving on very slippery surfaces, or
hydroplaning. ESC also cannot prevent accidents re-
sulting from loss of vehicle control due to inappropri-
ate driver input for the conditions. Only a safe, atten-
tive, and skillful driver can prevent accidents. The
capabilities of an ESC equipped vehicle must never be
exploited in a reckless or dangerous manner which
could jeopardize the user ’s safety or the safety of
others.

Electronic Stability Control (ESC) Operating Modes
The ESC system may have five available operating modes:
ESC On
This is the normal operating mode for the ESC system.
Whenever the vehicle is started, the ESC system will be in
this mode. The ESC On mode should be used for most
driving situations. The ESC should only be turned OFF for
specific reasons as noted in the following paragraphs.
ESC Full Off
The ESC Off mode is intended for off-highway or off-road
use only and should not be used on any public roadways.In this mode, all TCS and ESC stability features are turned
OFF. To enter the “Full Off” mode, push and hold the
“ESC” switch for five seconds while the vehicle is stopped
with the engine running. After five seconds, a chime will
sound, the “ESC OFF” telltale will illuminate, and the “ESC
OFF” will display in the vehicle cluster (left of the odom-
eter). The “ESC OFF” message may appear in the instru-
ment cluster display. Refer to “Instrument Cluster Display”
in “Understanding Your Instrument Panel” for further
information. To turn ESC ON again, momentarily push the
“ESC” switch.
WARNING!
With the ESC switched OFF, the enhanced vehicle sta-
bility offered by ESC is unavailable. In an emergency
evasive maneuver, the ESC system will not engage to
assist in maintaining stability. The “Full Off” ESC mode
is intended for off-highway or off-road only.
Sport Mode — If Equipped
Sport mode has reduced traction control and reduced
stability control. To enter the “Sport Mode” mode, push the
“ESC” switch once (located on the steering wheel). The
“ESC OFF” telltale will illuminate, and the “ESC SPORT”

Your Instrument Panel” for further information.
WARNING!
When in Sport Mode, the TCS functionality of ESC,
(except for the limited slip feature described in the
TCS section), has been disabled, the “ESC Sport Light”
will illuminate, and the “ESC SPORT” message will
display in the vehicle cluster. When in Sport Mode, the
engine power reduction feature of TCS is disabled, and
the enhanced vehicle stability offered by the ESC
system is reduced.
Track Mode — If Equipped
Track Mode has no traction control and has reduced
stability control. To enter the “Track Mode” mode, push the
“ESC” switch twice. The “ESC OFF” telltale will illuminate,
and the “ESC TRACK” message will display in the vehicle
cluster (left of the odometer). Refer to “Instrument Cluster
Display” in “Understanding Your Instrument Panel” for

WARNING!
When in Track Mode, the TCS functionality of ESC,
(except for the limited slip feature described in the
TCS section), has been disabled, the “ESC Track Light”
will illuminate, and the “ESC TRACK” message will
display in the vehicle cluster. When in Track Mode, the
engine power reduction feature of TCS is disabled, and
the enhanced vehicle stability offered by the ESC
system is greatly reduced. Track Mode is intended for
off-highway or off-road only.
Rain Mode
Rain mode offers increased traction control and stability
control for low traction conditions such as wet roads, dry
roads during cold temperatures, or when the driver wants
enhanced stability due to lack of familiarity or experience
with the vehicle’s response. To enter the “Rain Mode”
mode, push the “ESC” switch three times. The “ESC Rain
Light” will illuminate, and the “ESC RAIN” message will
display in the vehicle cluster (left of the odometer). Refer to

FUEL REQUIREMENTS
8.4L Engine
The 8.4L engine is designed to meet all
emissions regulations, provide optimal
fuel economy and performance when
using high-quality unleaded “Pre-
mium” 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 in 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 your dealer immedi-
ately. 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.
Poor quality gasoline can cause problems such as hard
starting, stalling, and hesitations. If you experience these
symptoms, try another brand of gasoline before consider-
ing service for the vehicle.
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 specifi-
cally blended to reduce vehicle emissions and improve air
quality.
The use of reformulated gasoline is recommended. Prop-
erly blended reformulated gasoline will provide improved
performance and durability of engine and fuel system
components.
Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline with oxygen-
ates such as ethanol.
CAUTION!
DO NOT use gasoline containing methanol or gasoline
containing more than 10% ethanol (E-10). Use of these
blends may result in starting and drivability problems,
damage critical fuel system components, cause emis-
sions to exceed the applicable standard, and/or cause
the “Malfunction Indicator Light” to illuminate. Please
5
STARTING AND OPERATING 235

CAUTION!(Continued)
observe pump labels as they should clearly communi-
cate if a fuel contains greater than 10% ethanol (E-10).
Problems that result from using gasoline containing more
than 10% ethanol (E-10) or gasoline containing methanol
are not the responsibility of the manufacturer and may
void or not be covered under New Vehicle Limited War-
ranty.
E-85 Usage In Non-Flex Fuel Vehicles
Non-Flex Fuel Vehicles (FFV) are compatible with gasoline
containing up to 10% ethanol (E-10). Gasoline with higher
ethanol content may void the New Vehicle Limited War-
ranty.
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.
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. Gaso-
line 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.
236 STARTING AND OPERATING

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 Gaso-
line contains a higher level of detergents
to further aide in minimizing engine
and fuel system deposits. When avail-
able, 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 dia-
phragm materials.
Fuel System Cautions
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 perfor-
mance and damage the emissions 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 your 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 metha-
nol. Fuel system damage or vehicle performance
problems resulting from the use of such fuels or
additives is not the responsibility of the manufac-
turer and may void or not be covered under the New
Vehicle Limited Warranty.

NOTE:Intentional tampering with the emissions control
system can result in civil penalties being assessed against
you.
Carbon Monoxide Warnings
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon mon-
oxide 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 main-
tenance. Have the exhaust system inspected every
time the vehicle is raised. Have any abnormal condi-
tions repaired promptly. Until repaired, drive with
all side windows fully open.
ADDING FUEL
1. Push the fuel filler door release switch (located in the driver’s door map pocket).
2. Open the fuel filler door.
NOTE: In certain cold conditions, ice may prevent the fuel
door from opening. If this occurs, lightly push on the fuel
door to break the ice buildup and re-release the fuel door
using the inside release button. Do not pry on the door.
3. There is no fuel filler cap. A flapper door inside the pipe seals the system.
4. Insert the fuel nozzle fully into the filler pipe – the nozzle opens and holds the flapper door while refuel-
ing.
NOTE: Only the correct size nozzle opens the latches
allowing the flapper door to open.
5. Fill the vehicle with fuel – when the fuel nozzle “clicks” or shuts off the fuel tank is full.
6. Remove the fuel nozzle and close the fuel door.
238 STARTING AND OPERATING

NOTE:A funnel is provided (located in the trunk in the
spare tire area) to open the flapper door to allow for
emergency refueling with a gas can.
CAUTION!
To avoid fuel spillage and overfilling, do not “top off”
the fuel tank after filling.
WARNING!
• Never have any smoking materials lit in or near the
vehicle when the fuel door is open or the tank is
being filled.
• Never add fuel when the engine is running. This is
in violation of most state and federal fire regulations
and may cause the “Malfunction Indicator Light” to
turn on.
• A fire may result if fuel is pumped into a portable
container that is inside of a vehicle. You could be
burned. Always place fuel containers on the ground
while filling.
Emergency Fuel Filler Door Release
If you are unable to open the fuel filler door, use the fuel
filler door emergency release procedure by following the
proceeding steps.
1. Open the liftgate.
2. Locate the carpet access door (on the right side inner trim panel of the trunk).
