Maintaining Your Air Bag System
WARNING!
•Modifications to any part of the air bag system could
cause it to fail when you need it. You could be
injured if the air bag system is not there to protect
you. Do not modify the components or wiring, in-
cluding adding any kind of badges or stickers to the
steering wheel hub trim cover or the upper passenger
side of the instrument panel. Do not modify the front
bumper, vehicle body structure, or add aftermarket
side steps or running boards.
• It is dangerous to try to repair any part of the air bag
system yourself. Be sure to tell anyone who works on
your vehicle that it has an air bag system.
• Do not attempt to modify any part of your air bag
system. The air bag may inflate accidentally or may
not function properly if modifications are made.
Take your vehicle to an authorized dealer for any air
bag system service. If your seat, including your trim
cover and cushion, needs to be serviced in any way
(including removal or loosening/tightening of seat
attachment bolts), take the vehicle to an authorized

WARNING! (Continued)
dealer. Only manufacturer approved seat accessories
may be used. If it is necessary to modify the air bag
system for persons with disabilities, contact an au-
thorized dealer.
Event Data Recorder (EDR)
This vehicle is equipped with an event data recorder
(EDR). The main purpose of an EDR is to record, in certain
crash or near crash-like situations, such as an air bag
deployment or hitting a road obstacle, data that will assist
in understanding how a vehicle’s systems performed. The
EDR is designed to record data related to vehicle dynamics
and safety systems for a short period of time, typically 30
seconds or less. The EDR in this vehicle is designed to
record such data as:
•How various systems in your vehicle were operating;
• Whether or not the driver and passenger safety belts
were buckled/fastened;
• How far (if at all) the driver was depressing the accel-
erator and/or brake pedal; and,
• How fast the vehicle was traveling.5
SAFETY 179

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
immediately. Do not disassemble or modify the system.
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 system inspected at your authorized dealer as
soon as possible. After the bulb check, this light will
illuminate with a single chime when a fault with the Air
Bag System has been detected. It will stay on until the
fault is removed. If the light comes on intermittently or
remains on while driving, have your authorized dealer
service the vehicle immediately.
Refer to “Occupant Restraint Systems” in “Safety” for
further information.
Defroster
Check operation by selecting the defrost mode and place
the blower control on high speed. You should be able to
feel the air directed against the windshield. See your
authorized dealer for service if your defroster is inoper-
able.
Floor Mat Safety Information
Always use floor mats designed to fit your vehicle. Only
use a floor mat that does not interfere with the operation of
the accelerator, brake or clutch pedals. Only use a floor mat
that is securely attached using the floor mat fasteners so it
cannot slip out of position and interfere with the accelera-
tor, brake or clutch pedals or impair safe operation of your
vehicle in other ways.
WARNING!
An improperly attached, damaged, folded, or stacked
floor mat, or damaged floor mat fasteners may cause
your floor mat to interfere with the accelerator, brake,

WARNING!(Continued)
be in a vehicle unattended is dangerous for a number
of reasons. A child or others could be seriously or
fatally injured. Children should be warned not to
touch the parking brake, brake pedal or the gear
selector.
• When exiting the vehicle, always make sure the
keyless ignition node is in the OFF mode, remove the
key fob from the vehicle and lock the vehicle.
• Do not leave the key fob in or near the vehicle or in
a location accessible to children, and do not leave the
ignition of a vehicle equipped with Keyless Enter-
N-Go in the ACC or ON/RUN mode. A child could
operate power windows, other controls, or move the
vehicle.
• Be sure the parking brake is fully disengaged before
driving; failure to do so can lead to brake failure and
a collision.
• Always fully apply the parking brake when leaving
your vehicle, or it may roll and cause damage or
injury. Also be certain to leave the transmission in
PARK. Failure to do so may allow the vehicle to roll
and cause damage or injury.
CAUTION!
If the Brake Warning Light remains on with the park-
ing brake released, a brake system malfunction is
indicated. Have the brake system serviced by an au-
thorized dealer immediately.
MANUAL TRANSMISSION — IF EQUIPPED
Six-Speed Manual Transmission
WARNING!
You or others could be injured if you leave the vehicle
unattended without having the park brake fully ap-
plied. The park brake should always be applied when
the driver is not in the vehicle, especially on an incline.
CAUTION!
• Never drive with your foot resting on the clutch
pedal, or try to hold the vehicle on a hill with the
clutch pedal partially engaged, as this will cause
abnormal wear on the clutch. Refer to “Electronic

STARTING AND OPERATING 215

NOTE:In cases where the instrument cluster message
indicates the transmission may not re-engage after engine
shutdown, perform this procedure only in a desired loca-
tion (preferably, at an authorized dealer).
1. Stop the vehicle.
2. Shift the transmission into PARK, if possible. If not, shift the transmission to NEUTRAL.
3. Push and hold the ignition switch until the engine turns OFF.
4. Wait approximately 30 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no longer detected, the transmission will return to normal
operation.
NOTE: Even if the transmission can be reset, we recom-
mend that you visit an authorized dealer at your earliest
possible convenience. An authorized dealer has diagnostic
equipment to assess the condition of your transmission.
If the transmission cannot be reset, authorized dealer
service is required.AutoStick
AutoStick is a driver-interactive transmission feature pro-
viding manual shift control, giving you more control of the
vehicle. AutoStick allows you to maximize engine braking,
eliminate undesirable upshifts and downshifts, and im-
prove overall vehicle performance.
This system can also provide you with more control during
passing, city driving, cold slippery conditions, mountain
driving, and many other situations.

STARTING AND OPERATING 227

8. Rotors that pulsate during track use should be replaced.Resurfacing of the rotors is not recommended, as it
removes mass from the rotor, reducing its thermal
capacity. Resurfacing also thins the rotor cheek, making
it less robust and increasing the likelihood of pulsation
in further track use.
FUEL SAVER TECHNOLOGY 6.4L ONLY — IF
EQUIPPED
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: This system may take some time to return to full
functionality after a battery disconnect.
HYDRAULIC POWER STEERING — IF EQUIPPED
The hydraulic power steering system is sport tuned and
will give you good vehicle response and increased ease of
maneuverability in tight spaces. The system will provide
mechanical steering capability if power assist is lost. If for some reason the power assist is interrupted, it will
still be possible to steer your vehicle. Under these condi-
tions, you will observe a substantial increase in steering
effort, especially at very low vehicle speeds and during
parking maneuvers.
NOTE:
•
Increased noise levels at the end of the steering wheel
travel are considered normal and do not indicate that
there is a problem with the power steering system.
• Upon initial start-up in cold weather, the power steering
pump may make noise for a short amount of time. This
is due to the cold, thick fluid in the steering system. This
noise should be considered normal, and it does not in
any way damage the steering system.
WARNING!
Continued operation with reduced power steering as-
sist could pose a safety risk to yourself and others.
Service should be obtained as soon as possible.
6
STARTING AND OPERATING 235

CAUTION!
Prolonged operation of the steering system at the end
of the steering wheel travel will increase the steering
fluid temperature and it should be avoided when
possible. Damage to the power steering pump may
occur.
Power Steering Fluid Check
Checking the power steering fluid level at a defined service
interval is not required. The fluid should be checked at
every oil change if a leak is suspected, abnormal noises are
apparent, and/or the system is not functioning as antici-
pated. Coordinate inspection efforts through an authorized
dealer.
WARNING!
Fluid level should be checked on a level surface and
with the engine off to prevent injury from moving
parts and to ensure accurate fluid level reading. Do not
overfill. Use only manufacturer’s recommended power
steering fluid.
CAUTION!
Do not use chemical flushes in your power steering
system as the chemicals can damage your power steer-
ing components. Such damage is not covered by the
New Vehicle Limited Warranty.
If necessary, add fluid to restore to the proper indicated
level. With a clean cloth, wipe any spilled fluid from all
surfaces. Refer to “Fluids And Lubricants” in “Technical
Specifications” for further information.
ELECTRIC POWER STEERING — IF EQUIPPED
The electric power steering system will give you good
vehicle response and increased ease of maneuverability in
tight spaces. The system will vary its assist to provide light
efforts while parking and good feel while driving. If the
electric steering system experiences a fault that prevents it
from providing assist, you will still have the ability to steer
the vehicle manually.
Alternate electric power steering efforts can be selected
through the Uconnect System. Refer to “Drive Modes” in
this section for further information.
236 STARTING AND OPERATING

WARNING!
Continued operation with reduced assist could pose a
safety risk to yourself and others. Service should be
obtained as soon as possible.If the Steering icon is displayed and the “SER-
VICE POWER STEERING” or the “POWER
STEERING ASSIST OFF – SERVICE SYSTEM”
message is displayed within the instrument clus-
ter, this indicates the vehicle needs to be taken to the dealer
for service. Refer to “Instrument Cluster Display” in “Get-
ting To Know Your Instrument Panel” for further informa-
tion.
NOTE:
• Even if the power steering assistance is no longer
operational, it is still possible to steer the vehicle. Under
these conditions there will be a substantial increase in
steering effort, especially at low speeds and during
parking maneuvers.
• If the condition persists, see your authorized dealer for
service.
SPEED CONTROL — IF EQUIPPED
When engaged, the Speed Control takes over accelerator
operations at speeds greater than 25 mph (40 km/h).
The Speed Control buttons are located on the right side of
the steering wheel.
Speed Control Buttons
1 — On/Off 4 — SET (-)/Decel
2 — SET (+)/Accel 5 — CANC/Cancel
3 — RES/Resume

STARTING AND OPERATING 237

•Do not remove any screws from the sensor. Doing so
could cause an ACC system malfunction or failure and
require a sensor realignment.
• If the sensor or front end of the vehicle is damaged due
to a collision, see your authorized dealer for service.
• Do not attach or install any accessories near the sensor,
including transparent material or aftermarket grilles.
Doing so could cause an ACC system failure or malfunc-
tion.
When the condition that deactivated the system is no
longer present, the system will return to the “Adaptive
Cruise Control Off” state and will resume function by
simply reactivating it.
NOTE:
• If the “ACC/FCW Unavailable Wipe Front Radar Sen-
sor” message occurs frequently (e.g. more than once on
every trip) without any snow, rain, mud, or other
obstruction, have the radar sensor realigned at your
authorized dealer.
• Installing a snow plow, front-end protector, an aftermar-
ket grille or modifying the grille is not recommended.
Doing so may block the sensor and inhibit ACC/FCW
operation.Service ACC/FCW Warning
If the system turns off, and the instrument cluster displays
“ACC/FCW Unavailable Service Required” or “Cruise/
FCW Unavailable Service Required”, there may be an
internal system fault or a temporary malfunction that
limits ACC functionality. Although the vehicle is still
drivable under normal conditions, ACC will be temporar-
ily unavailable. If this occurs, try activating ACC again
later, following an ignition cycle. If the problem persists,
see your authorized dealer.
Precautions While Driving With ACC
In certain driving situations, ACC may have detection
issues. In these cases, ACC may brake late or unexpectedly.
The driver needs to stay alert and may need to intervene.
Towing A Trailer
Towing a trailer is not advised when using ACC.
252 STARTING AND OPERATING

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. Refer to “Instrument Cluster Dis-
play” in “Getting To Know Your Instrument Panel” for
further information. When the gear selector is moved to
REVERSE and the system is disabled, the instrument
cluster display will display the “ParkSense Off” message
for as long as the vehicle is in REVERSE.
The ParkSense switch LED will be on when ParkSense is
disabled or defective. The ParkSense switch LED will be off
when the system is enabled. If the ParkSense switch is
pushed and the system is disabled or requires service, the
ParkSense switch LED will blink momentarily and then the
LED will be on.
Service The ParkSense Rear Park Assist System
During vehicle start up, when the ParkSense Rear Park
Assist System has detected a faulted condition, the instru-
ment cluster will actuate a single chime, once per ignition
cycle and it will display the “PARKSENSE UNAVAILABLE WIPE REAR SENSORS” or “PARKSENSE UNAVAILABLE
SERVICE REQUIRED” message for five seconds. Refer to
“Instrument Cluster Display” in “Getting To Know Your
Instrument Panel” for further information.
When the gear selector is moved to REVERSE and the
system has detected a faulted condition, the instrument
cluster display will display the “PARKSENSE UNAVAIL-
ABLE WIPE REAR SENSORS” or “PARKSENSE UN-
AVAILABLE SERVICE REQUIRED” message for as long as
the vehicle is in REVERSE. Under this condition, ParkSense
will not operate.
If “PARKSENSE UNAVAILABLE WIPE REAR SENSORS”
appears in the instrument cluster display, make sure the
outer surface and the inside of the rear fascia/bumper is
clean and clear of snow, ice, mud, dirt or other obstruction,
and then cycle the ignition. If the message continues to
appear see an authorized dealer.
If “PARKSENSE UNAVAILABLE SERVICE REQUIRED”
