ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated Onboard
Diagnostic system called OBD II. This system monitors the
performance of the emissions, engine, and transmission
control systems. When these systems are operating prop-
erly, your vehicle will provide excellent performance and
fuel economy, as well as engine emissions well within
current government regulations.
If any of these systems require service, the OBD II system
will turn on the Malfunction Indicator Light (MIL). It will
also store diagnostic codes and other information to assist
your service technician in making repairs. Although your
vehicle will usually be drivable and not need towing, see
an authorized dealer for service as soon as possible.
CAUTION!
•Prolonged driving with the MIL on could cause
further damage to the emission control system. It
could also affect fuel economy and driveability. The
vehicle must be serviced before any emissions tests
can be performed.
• If the MIL is flashing while the vehicle is running,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.
Onboard Diagnostic System (OBD II) Cybersecurity
Your vehicle is required to have an Onboard Diagnostic
system (OBD II) and a connection port to allow access to
information related to the performance of your emissions
controls. Authorized service technicians may need to ac-
cess this information to assist with the diagnosis and
service of your vehicle and emissions system.
WARNING!
• ONLY an authorized service technician should con-
nect equipment to the OBD II connection port in
order to read the VIN, diagnose, or service your
vehicle.
• If unauthorized equipment is connected to the OBD
II connection port, such as a driver-behavior tracking
device, it may:
• Be possible that vehicle systems, including safety
related systems, could be impaired or a loss of
vehicle control could occur that may result in an
accident involving serious injury or death.
• Access, or allow others to access, information
stored in your vehicle systems, including personal
information.
170 GETTING TO KNOW YOUR INSTRUMENT PANEL

For vehicles not equipped with an instrument cluster
display, perform the following steps:
1. Center the steering wheel (front wheels pointingstraight forward).
2. Shift the transmission into PARK.
3. Apply the parking brake.
4. Start the engine.
5. Rotate the steering wheel slightly more than one-half turn to the left.
6. Push the “ESC Off” button located in the lower switch bank below the climate control four times within 20
seconds. The “ESC Off Indicator Light” should turn on
and turn off two times.
7. Rotate the steering wheel back to center and then an additional slightly more than one-half turn to the right.
8. Turn the ignition to the OFF mode and then back to ON. If the sequence was completed properly, the “ESC Off
Indicator Light” will blink several times to confirm HSA
is disabled.
9. Repeat these steps if you want to return this feature to its previous setting.Towing With HSA
HSA will also provide assistance to mitigate roll back while
towing a trailer.
WARNING!
•If you use a trailer brake controller with your trailer,
the trailer brakes may be activated and deactivated
with the brake switch. If so, there may not be enough
brake pressure to hold both the vehicle and the
trailer on a hill when the brake pedal is released. In
order to avoid rolling down an incline while resum-
ing acceleration, manually activate the trailer brake
or apply more vehicle brake pressure prior to releas-
ing the brake pedal.
• HSA is not a parking brake. Always apply the
parking brake fully when exiting your vehicle. Also,
be certain to place the transmission in PARK.
• Failure to follow these warnings can result in a
collision or serious personal injury.
178 SAFETY

NOTE:
•The “ESC Activation/Malfunction Indicator Light” and
the “ESC OFF Indicator Light” come on momentarily
each time the ignition is turned ON.
• Each time the ignition is turned ON, the ESC system will
be on even if it was turned off previously.
• The ESC system will make buzzing or clicking sounds
when it is active. This is normal; the sounds will stop
when ESC becomes inactive following the maneuver
that caused the ESC activation.
The “ESC OFF Indicator Light” indicates the
customer has elected to have the Electronic Sta-
bility Control (ESC) in a reduced mode.
Electronic Roll Mitigation (ERM)
This system anticipates the potential for wheel lift by
monitoring the driver ’s steering wheel input and the speed
of the vehicle. When ERM determines that the rate of
change of the steering wheel angle and vehicle’s speed are
sufficient to potentially cause wheel lift, it then applies the
appropriate brake and may also reduce engine power to
lessen the chance that wheel lift will occur. ERM can only
reduce the chance of wheel lift occurring during severe or evasive driving maneuvers; it cannot prevent wheel lift
due to other factors, such as road conditions, leaving the
roadway, or striking objects or other vehicles.
WARNING!
Many factors, such as vehicle loading, road conditions
and driving conditions, influence the chance that
wheel lift or rollover may occur. ERM cannot prevent
all wheel lift or roll overs, especially those that involve
leaving the roadway or striking objects or other ve-
hicles. The capabilities of an ERM-equipped vehicle
must never be exploited in a reckless or dangerous
manner which could jeopardize the user’s safety or the
safety of others.
Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize an excessively
swaying trailer and will take the appropriate actions to
attempt to stop the sway. TSC will become active automati-
cally once an excessively swaying trailer is recognized.
Note that TSC cannot stop all trailers from swaying.
Always use caution when towing a trailer and follow the
trailer tongue weight recommendations. Refer to “Trailer
Towing” in “Starting And Operating” for more informa-
tion. When TSC is functioning, the “ESC Activation/

AUXILIARY DRIVING SYSTEMS
Blind Spot Monitoring (BSM) — If Equipped
The Blind Spot Monitoring (BSM) system uses two radar
sensors, located inside the rear bumper fascia, to detect
highway licensable vehicles (automobiles, trucks, motor-
cycles, etc.) that enter the blind spot zones from the
rear/front/side of the vehicle.
When the vehicle is started, the BSM warning light will be
momentarily illuminated in both outside rear view mirrorsto let the driver know that the system is operational. The
BSM system sensors operate when the vehicle is in any
forward gear or REVERSE.
The BSM detection zone covers approximately one lane on
both sides of the vehicle 12 ft (3.8 m). The zone length starts
at the side of the vehicle, near the B-Pillar, and extends
approximately 10 ft (3 m) beyond the rear bumper of the
vehicle. The BSM system monitors the detection zones on
both sides of the vehicle when the vehicle speed has
reached approximately 6 mph (10 km/h) or higher and will
alert the driver of vehicles in these areas.
NOTE:
•
The BSM system DOES NOT alert the driver about
rapidly approaching vehicles that are outside the detec-
tion zones.
• The BSM system detection zone DOES NOT change if
your vehicle is towing a trailer. Therefore, visually verify
the adjacent lane is clear for both your vehicle and trailer
before making a lane change. If the trailer or other object
(i.e., bicycle, sports equipment) extends beyond the side
of your vehicle, this may result in random false detec-
tions on the trailer, and false chimes when the turn
signal is used. Refer to “Uconnect Settings” in “Multi-
media” for more information.

262 STARTING AND OPERATING

WARNING!
Do not coast in NEUTRAL and never turn off the
ignition to coast down a hill. These are unsafe practices
that limit your response to changing traffic or road
conditions. You might lose control of the vehicle and
have a collision.
CAUTION!
Towing the vehicle, coasting, or driving for any other
reason with the transmission in NEUTRAL can cause
severe transmission damage.
Refer to “Recreational Towing” in “Starting And Op-
erating” and “Towing A Disabled Vehicle” in “In Case
Of Emergency” for further information.
DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and downshifts,
and the best fuel economy. The transmission automatically
upshifts through all forward gears. The DRIVE position
provides optimum driving characteristics under all normal
operating conditions. When frequent transmission shifting occurs (such as when
operating the vehicle under heavy loading conditions, in
hilly terrain, traveling into strong head winds, or while
towing a heavy trailer), use the AutoStick shift control
(refer to AutoStick in this section for further information) to
select a lower gear. Under these conditions, using a lower
gear will improve performance and extend transmission
life by reducing excessive shifting and heat buildup.
During cold temperatures, transmission operation may be
modified depending on engine and transmission tempera-
ture as well as vehicle speed. This feature improves warm
up time of the engine and transmission to achieve maxi-
mum efficiency. Engagement of the torque converter clutch
is inhibited until the transmission fluid is warm. Normal
operation will resume once the transmission temperature
has risen to a suitable level.
Manual (M)
The MANUAL (M, +/-) position (beside the DRIVE posi-
tion) enables full manual control of transmission shifting
(also known as AutoStick mode; refer to “AutoStick” in this
section for further information). Toggling the gear selector
forward (-) or rearward (+) while in the MANUAL

eliminate undesirable upshifts and downshifts, and im-
prove overall vehicle performance. This system can also
provide you with more control during passing, city driv-
ing, cold slippery conditions, mountain driving, trailer
towing, and many other situations.
Operation
To activate AutoStick mode, move the gear selector into the
MANUAL (M) position (beside the DRIVE position), or tap
one of the shift paddles on the steering wheel (if equipped).
Tapping the (-) shift paddle (if equipped) to enter
AutoStick mode will downshift the transmission to the
next lower gear, while tapping (+) to enter AutoStick mode
will retain the current gear. The current transmission gear
will be displayed in the instrument cluster. In AutoStick
mode, you can use the gear selector (in the MANUAL
position), or the shift paddles (if equipped), to manually
shift the transmission. Tapping the gear selector forward (-)
while in the MANUAL (M) position, or tapping the (-) shift
paddle (if equipped), will downshift the transmission to
the next lower gear. Tapping the selector rearward (+) (or
tapping the (+) shift paddle, if equipped) will command an
upshift.NOTE:
The shift paddles (if equipped) may be disabled (or
re-enabled, as desired) using the Uconnect Personal Set-
tings.
In AutoStick mode, the transmission will shift up or down
when (+/-) is manually selected by the driver, unless an
engine lugging or overspeed condition would result. It will
remain in the selected gear until another upshift or down-
shift is chosen, except as described below.
• The transmission will automatically downshift as the
vehicle slows (to prevent engine lugging) and will
display the current gear.
• The transmission will automatically downshift to first
gear when coming to a stop. After a stop, the driver
should manually upshift (+) the transmission as the
vehicle is accelerated.
• You can start out, from a stop, in first or second gear.
Tapping (+) at a stop will allow starting in second gear.
Starting out in second gear can be helpful in snowy or
icy conditions.
• If a requested downshift would cause the engine to
over-speed, that shift will not occur.
• The system will ignore attempts to upshift at too low of
a vehicle speed.
6
STARTING AND OPERATING 281

When operating your vehicle in LOW RANGE, the engine
speed is approximately three times that of the AWD AUTO
position at a given road speed. Take care not to overspeed
the engine and do not exceed 25 mph (40 km/h).
Proper operation of all-wheel drive vehicles depends on
tires of equal size, type and circumference on each wheel.
Any difference in tire size can cause damage to the transfer
case.
Because all-wheel drive provides improved traction, there
is a tendency to exceed safe turning and stopping speeds.
Do not go faster than road conditions permit.
For additional information on the appropriate use of each
transfer case mode position, see the information below:
AWD Auto
All-Wheel Drive Auto Range – This range sends power to
the rear wheels. The all-wheel drive system will be auto-
matically engaged when the vehicle senses a loss of trac-
tion. Additional traction for varying road conditions.LOW Range
All-Wheel Drive Low Range – This range provides low
speed all-wheel drive. Locks the front and rear driveshafts
together forcing the front and rear wheels to rotate at the
same speed. Additional traction and maximum pulling
power for loose, slippery road surfaces only. Do not exceed
25 mph (40 km/h).
NEUTRAL (N)
NEUTRAL – This range disengages both the front and rear
driveshafts from the powertrain. To be used for flat towing
behind another vehicle. Refer to “Recreational Towing” in
“Starting And Operating” for further information.
WARNING!
You or others could be injured or killed if you leave the
vehicle unattended with the transfer case in the NEU-
TRAL position without first fully engaging the park-
ing brake. The transfer case NEUTRAL position disen-
gages both the front and rear drive shafts from the
powertrain and will allow the vehicle to roll, even if
the transmission is in PARK. The parking brake
should always be applied when the driver is not in the
vehicle.
