Enhanced Accident Response System
In the event of an impact, if the communication network
remains intact, and the power remains intact, depending
on the nature of the event, the ORC will determine
whether to have the Enhanced Accident Response Sys-
tem perform the following functions:
•Cut off fuel to the engine.
• Flash hazard lights as long as the battery has power or
until the hazard light button is pressed. The hazard
lights can be deactivated by pressing the hazard light
button.
• Turn on the interior lights, which remain on as long as
the battery has power.
• Unlock the power door locks.
Enhanced Accident Response System Reset
Procedure
In order to reset the Enhanced Accident Response System
functions after an event, the ignition must be changed
from the START or ON/RUN position to the OFF posi-
tion. Carefully check the vehicle for fuel leaks in the
engine compartment and on the ground near the engine
compartment and fuel tank before resetting the system
and starting the engine.
Air Bag Warning Light
The air bags must be ready to inflate for your
protection in a collision. The Occupant Re-
straint Controller (ORC) monitors the internal
circuits and interconnecting wiring associated
with air bag system electrical components.
The ORC monitors the readiness of the electronic parts of
the air bag system whenever the ignition is placed in the
2

START or ON/RUN position. If the ignition is in the OFF
position or in the ACC position, the air bag system is not
on and the air bags will not inflate.
The ORC contains a backup power supply system that
may deploy the air bags even if the battery loses power or
it becomes disconnected prior to deployment.
The ORC turns on the Air Bag Warning Light in the
instrument panel for approximately four to eight seconds
for a self-check when the ignition is first placed in the
ON/RUN position. After the self-check, the Air Bag
Warning Light will turn off. If the ORC detects a mal-
function in any part of the system, it turns on the Air Bag
Warning Light, either momentarily or continuously. A
single chime will sound to alert you if the light comes on
again after initial startup.
The ORC also includes diagnostics that will illuminate
the instrument panel Air Bag Warning Light if a malfunc-
tion is detected that could affect the air bag system. Thediagnostics also record the nature of the malfunction.
While the air bag system is designed to be maintenance
free, if any of the following occurs, have an authorized
dealer service the air bag system immediately.
•
The Air Bag Warning Light does not come on during
the four to eight seconds when the ignition is first
placed in the ON/RUN position.
• The Air Bag Warning Light remains on after the four to
eight-second interval.
• The Air Bag Warning Light comes on intermittently or
remains on while driving.
NOTE: If the speedometer, tachometer, or any engine
related gauges are not working, the Occupant Restraint
Controller (ORC) may also be disabled. In this condition
the air bags may not be ready to inflate for your protec-
tion. Have an authorized dealer service the air bag
system immediately.

WARNING!
•The top tether anchorages are not visible until the
gap panel is folded down. Do not use the visible
cargo tie down hooks, located on the floor behind
the seats, to attach a child restraint tether anchor.
• An incorrectly anchored tether strap could lead to
increased head motion and possible injury to the
child. Use only the anchorage position directly
behind the child seat to secure a child restraint top
tether strap.
• If your vehicle is equipped with a split rear seat,
make sure the tether strap does not slip into the
opening between the seatbacks as you remove
slack in the strap.
Transporting Pets
Air Bags deploying in the front seat could harm your pet.
An unrestrained pet will be thrown about and possibly
injured, or injure a passenger during panic braking or in
a collision.
Pets should be restrained in the rear seat in pet harnesses
or pet carriers that are secured by seat belts.
ENGINE BREAK-IN RECOMMENDATIONS
The following tips will be helpful in obtaining optimum
performance and maximum durability for your new SRT
Vehicle.
Despite modern technology and World Class manufac-
turing methods, the moving parts of the vehicle must still
wear in with each other. This wearing in occurs mainly
during the first 500 miles (805 km) and continues through
the first oil change interval.

It is recommended for the operator to observe the follow-
ing driving behaviors during the new vehicle break-in
period:
0 to 100 miles (0 to 161 km):
•Do not allow the engine to operate at idle for an
extended period of time.
• Depress the accelerator pedal slowly and not more
than halfway to avoid rapid acceleration.
• Avoid aggressive braking.
• Drive with the engine speed less than 3,500 RPM.
• Maintain vehicle speed below 55 mph (88 km/h) and
observe local speed limits. 100 to 300 miles (161 to 483 km):
•
Depress the accelerator pedal slowly and not more
than halfway to avoid rapid acceleration in lower
gears (1st to 3rd gears).
• Avoid aggressive braking.
• Drive with the engine speed less than 5,000 RPM.
• Maintain vehicle speed below 70 mph (112 km/h) and
observe local speed limits.
300 to 500 miles (483 to 805 km):
• Exercise the full engine rpm range, shifting manually
(paddles or gear shift) at higher rpms when possible.
• Do not perform sustained operation with the accelera-
tor pedal at wide open throttle.
• Maintain vehicle speed below 85 mph (136 km/h) and
observe local speed limits.

483 to 805 km (300 to 500 miles):
•Exercise the full engine rpm range, shifting manually
(paddles or gear shift) at higher rpms when possible.
• Do not perform sustained operation with the accelera-
tor pedal at wide open throttle.
• Maintain vehicle speed below 136 km/h (85 mph) and
observe local speed limits.
For the first 1500 mi (2414 km):
• Do not participate in track events, sport driving
schools, or similar activities during the first 1500 mi
(2414 km).
NOTE: Check engine oil with every refueling and add if
necessary. Oil and fuel consumption may be higher
through the first oil change interval. Running the engine
with an oil level below the add mark can cause severe
engine damageSAFETY TIPS
Transporting Passengers
NEVER TRANSPORT PASSENGERS IN THE CARGO
AREA.
WARNING!
• Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build-up may
cause serious injury or death.
• It is extremely dangerous to ride in a cargo area,
inside or outside of a vehicle. In a collision, people
riding in these areas are more likely to be seriously
injured or killed.
•

Exhaust Gas
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO), which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing (CO),
follow these safety tips:
•Do not run the engine in a closed garage or in
confined areas any longer than needed to move
your vehicle in or out of the area.
•
If you are required to drive with the trunk/liftgate/rear
doors open, make sure that all windows are closed and
the climate control BLOWER switch is set at high
speed. DO NOT use the recirculation mode.
• If it is necessary to sit in a parked vehicle with the
engine running, adjust your heating or cooling
WARNING! (Continued)
controls to force outside air into the vehicle. Set the
blower at high speed.
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.
Whenever a change is noticed in the sound of the exhaust
system, when exhaust fumes can be detected inside the
vehicle, or when the underside or rear of the vehicle is
damaged, have a competent mechanic inspect the com-
plete exhaust system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts. Open
seams or loose connections could permit exhaust fumes
to seep into the passenger compartment. In addition,
inspect the exhaust system each time the vehicle is raised
for lubrication or oil change. Replace as required.
110 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks, and bulges.
Check the wheel nuts for tightness. Check the tires
(including spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, power steering fluid (if
equipped), or brake fluid leaks are suspected. The cause
should be located and corrected immediately.

•The engine must be running for the heated seats to
operate.
Vehicles Equipped With Remote Start
On models that are equipped with remote start, the
heated seats can be programmed to come on during a
remote start.
This feature can be programmed through the Uconnect
system. Refer to “Uconnect Settings” in “Understanding
Your Instrument Panel” for further information.
WARNING!
• Persons who are unable to feel pain to the skin
because of advanced age, chronic illness, diabetes,
spinal cord injury, medication, alcohol use, exhaus-
tion or other physical condition must exercise care
when using the seat heater. It may cause burns
(Continued)
WARNING! (Continued)
even at low temperatures, especially if used for
long periods of time.
• Do not place anything on the seat or seatback that
insulates against heat, such as a blanket or cushion.
This may cause the seat heater to overheat. Sitting
in a seat that has been overheated could cause
serious burns due to the increased surface tempera-
ture of the seat.
Rear Heated Seats — If Equipped
On some models, the two rear outboard seats may be
equipped with heated seats. There are two heated seat
switches that allow the rear passengers to operate the
seats independently. The heated seat switches for each
heater are located on the rear of the center console.
