MULTI DISPLACEMENT SYSTEM (MDS) - 5.7L
Engine Only
This feature offers improved fuel economy by shutting
off four of the engine’s eight cylinders during light load
and cruise conditions. The system is automatic with no
driver inputs or additional driving skills required.
NOTE:The MDS system may take some time to return
to full functionality after a battery disconnect.
TRACTION CONTROL SYSTEM (TCS) — IF
EQUIPPED
WARNING!
The Traction Control System (TCS) cannot prevent
the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded. The
TCS cannot prevent accidents, including those re-
sulting from excessive speed in turns, or hydroplan-
ing. Only a safe, attentive, and skillful driver can
prevent accidents. The capabilities of a TCS-
equipped vehicle must never be exploited in a reck-
less or dangerous manner, which could jeopardize
the user’s safety or the safety of others.
The Traction Control System (TCS) Indicator
Light, located in the instrument cluster, starts
to flash as soon as the tires lose traction and the
wheels begin to spin. This indicates that the
TCS is active. If the indicator light begins to flash during

CAUTION!
If the vehicle is towed with the front axle raised, the
engine must be shut off (key in the ignition switch to
the OFF/LOCK or ACC position). Otherwise, the ESP
will immediately be engaged and will apply the rear
wheel brakes.
Synchronizing ESP
The malfunction indicator light for the ESP is
combined with BAS indicator. If the power
supply is interrupted (battery disconnected or
discharged), the ESP/BAS malfunction indica-
tor light may illuminate with the engine running. If this
should occur, turn the steering wheel completely to the
left and then to the right. The ESP/BAS malfunction
indicator light should go out.
ESP/BAS Malfunction Indicator and ESP/TCS
Indicator Lights
The malfunction indicator light for the ESP is
combined with the BAS indicator. The yellow
ESP/BAS malfunction indicator light and the
yellow ESP/TCS indicator light in the instru-
ment cluster both come on when the ignition switch is
turned to the “ON” position. They should go out with the
engine running.
The system will turn the ESP/BAS malfunction indicator
light on continuously while the engine running if it
detects a malfunction in either the ESP or the BAS or
both. If the light remains on after several ignition cycles,
and you have driven the vehicle several miles at speeds
greater than 30 mph (48 km/h), and the ESP is synchro-
nized (refer to Synchronizing ESP), see your authorized
dealer as soon as possible to have the problem diagnosed
and corrected.

HAZARD WARNING FLASHER
The hazard flasher switch is located in the center of the
instrument panel below the center air outlets.
To engage the Hazard Warning Flashers, depress the
switch on the instrument panel. When the Hazard Warn-
ing Switch is activated, all directional turn signals will
flash on and off to warn oncoming traffic of an emer-
gency. Push the switch a second time to turn off the
flashers.This is an emergency warning system and it should not
be used when the vehicle is in motion. Use it when your
vehicle is disabled and it is creating a safety hazard for
other motorists.
When you must leave the vehicle to seek assistance, the
Hazard Warning Flashers will continue to operate even
though the ignition switch is OFF.
NOTE:With extended use, the Hazard Warning Flash-
ers may wear down your battery.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate ac-
tion.
•On the highways — Slow down.
•In city traffic — While stopped, put transmission in
neutral, but do not increase engine idle speed.

JUMP-STARTING PROCEDURES
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 hurt by the fan.
•Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic transmis-
sion cannot be started this way. Unburned fuel could
enter the catalytic converter and once the engine has
started, ignite and damage the converter and vehicle. If
the vehicle has a discharged battery, booster cables may
be used to obtain a start from another vehicle. This type
of start can be dangerous if done improperly, so follow
this procedure carefully.
•Battery fluid is a corrosive acid solution; do not allow
battery fluid to contact eyes, skin, or clothing. Don’t lean
over battery when attaching clamps or allow the clamps to
touch each other. If acid splashes in eyes or on skin, flush
contaminated area immediately with large quantities of
water.
•A battery generates hydrogen gas, which is flammable
and explosive. Keep flame or spark away from the vent
holes.
•Do not use a booster battery or any other booster source
with an output that exceeds 12 volts.
•The battery in this vehicle has a vent hose that should not
be disconnected and should only be replaced with a
battery of the same type (vented).
NOTE:The battery is stored under an access cover in
the trunk. Remote battery terminals are located in the
engine compartment for jump-starting.
1. Wear eye protection and remove any metal jewelry
such as watchbands or bracelets that might make an
inadvertent electrical contact.
2. When boost is provided by a battery in another
vehicle, park that vehicle within booster cable reach, but
do not allow the vehicles to touch one another.
WARNING!
Do not permit vehicles to touch each other as this
could establish a ground connection and personal
injury could result.
3. Set the parking brake, place the automatic transmis-
sion in PARK, and turn the ignition switch to the OFF (or
LOCK) position on both vehicles.
4. Turn off the heater, radio, and all unnecessary electri-
cal loads.

5. Connect one end of the jumper cable to the remote
jump-start positive battery post(+)in the engine com-
partment. Connect the other end of the same cable to the
positive terminal of the booster battery. Refer to the
following illustration for jump-starting connections.
6. Connect the other cable, first to the negative terminal
of the booster battery andthen to the engine ground (-)
of the vehicle with the discharged battery.Make sure
you have a good contact on the engine ground. Refer to
the following illustration for jump-starting connections.WARNING!
•You should not try to start your vehicle by push-
ing or towing.
•Do not connect the cable to the negative post of
the discharge battery. The resulting electrical
spark could cause the battery to explode.
•During cold weather when temperatures are be-
low freezing point, electrolyte in a discharged
battery may freeze. Do not attempt jump-starting
because the battery could rupture or explode. The
battery temperature must be brought up above
freezing point before attempting jump-start.
7. Start the engine in the vehicle that has the booster
battery. Let the engine idle a few minutes. Then, start the
engine in the vehicle with the discharged battery.
NOTE:For vehicles equipped with ESP, refer toSyn-
chronizing ESPunderElectronic Stability Programin
Section 5 of this manual if the ESP/BAS light (in the
instrument cluster) remains on continuously after start-
ing the engine of the vehicle with the discharged battery.

8. When removing the jumper cables, reverse the above
sequence exactly. Be careful of the moving belts and fan.
WARNING!
Any procedure other than above could result in:
1. Personal injury caused by electrolyte squirting
out the battery vent;
2. Personal injury or property damage due to battery
explosion;
3. Damage to charging system of booster vehicle or
of immobilized vehicle.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand, or snow, it
can often be moved by a rocking motion. Turn your
steering wheel right and left to clear the area around the
front wheels. Then shift back and forth between Reverse
and Drive. Usually the least accelerator pedal pressure to
maintain the rocking motion without spinning the
wheels is most effective.
NOTE:Turn off the Electronic Stability Program (ESP)
— if equipped, or Traction Control System (TCS) — if
equipped before rocking the vehicle. For details, refer to
“Electronic Stability Program,” or “Traction Control Sys-
tem” in this manual.

Loose Fuel Filler Cap
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
“Check Gascap” message will display in the Electronic
Vehicle Information Center (EVIC) — if equipped. If this
occurs, tighten the fuel filler cap properly and press the
odometer reset button to turn off the message. If the
problem continues, the message will appear the next time
the vehicle is started.
A loose, improperly installed, or damaged fuel filler cap
may also turn on the Malfunction Indicator Light (MIL).
EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass
an inspection of your vehicle’s emissions control system.
Failure to pass could prevent vehicle registration.
For states, which have an I/M (Inspection and
Maintenance) requirement, this check verifies the
following: the MIL (Malfunction Indicator Lamp)is functioning and is not on when the engine is running,
and that the OBD (On Board Diagnostic) system is ready
for testing.
Normally, the OBD system will be ready. The OBD
system maynotbe ready if your vehicle was recently
serviced, if you recently had a dead battery, or a battery
replacement. If the OBD system should be determined
not ready for the I/M test, your vehicle may fail the test.
Your vehicle has a simple ignition key actuated test,
which you can use prior to going to the test station. To
check if your vehicle’s OBD system is ready, you must do
the following:
1. Insert your ignition key into the ignition switch.
2. Turn the ignition to the ON position, but do not crank
or start the engine.
3. If you crank or start the engine, you will have to start
this test over.
4. As soon as you turn your key to the ON position, you
will see your MIL symbol come on as part of a normal
bulb check.
