WARNING!
In a collision, people riding in these
areas are more likely to be seriously
injured or killed.
• Do not allow people to ride in any area of
your vehicle that is not equipped with
seats and seat belts.
• Be sure everyone in your vehicle is in a
seat and using a seat belt properly.
Exhaust Gas
WARNING!
Exhaust gases can injure or kill. They con-
tain carbon monoxide (CO), which is col-
orless and odorless. Breathing it can make
you unconscious and can eventually poi-
son 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.
WARNING!
• If you are required to drive with the
trunk/liftgate/rear doors open, make sure
that all windows are closed and the cli-
mate control BLOWER switch is set at
high speed. DO NOT use the recircula-
tion mode.
• If it is necessary to sit in a parked vehicle
with the engine running, adjust your
heating or cooling controls to force out-
side air into the vehicle. Set the blower
at high speed.
The best protection against carbon monoxide
entry into the vehicle body is a properly main-
tained 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 ar-
eas for broken, damaged, deteriorated, or
mispositioned parts. Open seams or loose
connections could permit exhaust fumes to
seep into the passenger compartment. Inaddition, inspect the exhaust system each
time the vehicle is raised for lubrication or oil
change. Replace as required.
Safety Checks You Should Make Inside
The Vehicle
Seat Belts
Inspect the seat belt system periodically,
checking for cuts, frays, and loose parts.
Damaged parts must be replaced immedi-
ately. Do not disassemble or modify the sys-
tem.
Front seat belt assemblies must be replaced
after a collision. Rear seat belt assemblies
must be replaced after a collision if they have
been damaged (i.e., bent retractor, torn web-
bing, etc.). If there is any question regarding
seat belt or retractor condition, replace the
seat belt.
Air Bag Warning Light
The Air Bag warning lightwill turn on for
four to eight seconds as a bulb check when
the ignition switch is first turned to ON/RUN.
If the light is either not on during starting,
stays on, or turns on while driving, have the

placing the transmission in PARK. This sys-
tem also locks the transmission in PARK
whenever the ignition is in the OFF mode.
NOTE:
The transmission is NOT locked in PARK
when the ignition is in the ACC mode (even
though the engine will be off). Ensure that
the transmission is in PARK, and the ignition
isOFF(not in ACC mode) before exiting the
vehicle.
Brake/Transmission Shift Interlock
System
This vehicle is equipped with a Brake Trans-
mission Shift Interlock system (BTSI) that
holds the transmission gear selector in PARK
unless the brakes are applied. To shift the
transmission out of PARK, the engine must
be running and the brake pedal must be
pressed. The brake pedal must also be
pressed to shift from NEUTRAL into DRIVE or
REVERSE when the vehicle is stopped or
moving at low speeds.
Fuel Economy (ECO) Mode
The Fuel Economy (ECO) mode can improve

gaged, the vehicle control systems will
change the following:
• The transmission will upshift sooner and
downshift later.
• The overall driving performance will be
more conservative.
• Vehicles with Quadra-Lift air suspension
will operate in "Aero" mode over a broader
speed range. Refer to the section on
Quadra-Lift for further information.
• In SRT models, the transmission will
launch (from a stop) in second gear, and
the torque converter clutch may engage at
lower engine speeds and remain on longer.
• Some ECO mode functions may be tempo-
rarily inhibited based on temperature and
other factors.
Active Noise Cancellation — If Equipped
Your vehicle is equipped with an Active Noise
Cancellation System. This system uses four
microphones embedded in the headliner to
detect undesirable exhaust noise, which

Enabling And Disabling ParkSense
ParkSense can be enabled and disabled with
the ParkSense switch.
When the ParkSense switch is
pushed to disable the system, the
instrument cluster will display the
“PARKSENSE OFF” message for
approximately five seconds. When the gear
selector is moved to REVERSE and the sys-
tem is disabled, the instrument cluster dis-
play will display the “PARKSENSE OFF”
message for as long as the vehicle is in
REVERSE.
Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” in
your Owner’s Manual for further information.
The ParkSense switch LED will be on when
ParkSense is disabled or requires service.
The ParkSense switch LED will be off when
the system is enabled. If the ParkSenseswitch is pushed, and the system requires
service, the ParkSense switch LED will blink
momentarily, and then the LED will be on.
ParkSense System Usage Precautions
NOTE:
• Ensure that the rear bumper is free of snow,
ice, mud, dirt and debris to keep the
ParkSense system operating properly.
• Jackhammers, large trucks, and other vi-
brations could affect the performance of
ParkSense.
• When you turn ParkSense off, the instru-
ment cluster will display “PARKSENSE
OFF.” Furthermore, once you turn
ParkSense off, it remains off until you turn
it on again, even if you cycle the ignition.
• When you move the gear selector to the
REVERSE position and ParkSense is
turned off, the instrument cluster display
will display “PARKSENSE OFF” message
for as long as the vehicle is in REVERSE.
• ParkSense, when on, will reduce the vol-
ume of the radio when it is sounding a tone.• Clean the ParkSense sensors regularly, tak-
ing care not to scratch or damage them.
The sensors must not be covered with ice,
snow, slush, mud, dirt or debris. Failure to
do so can result in the system not working
properly. The ParkSense system might not
detect an obstacle behind the fascia/
bumper, or it could provide a false indica-
tion that an obstacle is behind the fascia/
bumper.
• Use the ParkSense switch to turn the
ParkSense system off if objects such as
bicycle carriers, trailer hitches, etc. are
placed within 12 inches (30 cm) from the
rear fascia/bumper. Failure to do so can
result in the system misinterpreting a close
object as a sensor problem, causing the
“PARKSENSE UNAVAILABLE SERVICE
REQUIRED” message to be displayed in
the instrument cluster display.
• ParkSense should be disabled when the
liftgate is in the open position and the
vehicle is in REVERSE. An open liftgate
could provide a false indication that an
obstacle is behind the vehicle.
