Security System Manual Override
The vehicle security alarm will not arm if you
lock the doors using the manual door lock
plunger.
PREMIUM VEHICLE
SECURITY ALARM — IF
EQUIPPED
The premium vehicle security alarm system
monitors the doors, hood latch, and liftgate
for unauthorized entry and the ignition switch
for unauthorized operation. The system also
includes a dual function intrusion sensor and
vehicle tilt sensor. The intrusion sensor moni-
tors the vehicle interior for motion. The ve-
hicle tilt sensor monitors the vehicle for any
tilting actions (tow away, tire removal, ferry
transport, etc). A siren with battery backup
which senses interruptions of power and
communications is also included.
If a perimeter violation triggers the security
system, the siren will sound for 29 seconds
and the exterior lights will flash followed byapproximately five seconds of no activity.
This will continue for eight cycles if no action
is taken to disarm the system.
To Arm The System
Follow these steps to arm the security alarm:
1. Remove the key from the ignition system,
refer to "Starting The Engine" in "Starting
And Operating" in your Owner’s manual
for further information.
• For vehicles equipped with Keyless
Enter-N-Go — Passive Entry, make
sure the vehicle ignition system is
"OFF."
• For vehicles not equipped with Keyless
Enter-N-Go — Passive Entry, make
sure the vehicle ignition system is
"OFF" and the key is physically re-
moved from the ignition.
2. Perform one of the following methods to
lock the vehicle:
• Push lock on the interior power door
lock switch with the driver and/or pas-
senger door open.• Push the lock button on the exterior
passive entry door handle with a key
fob available in the same exterior zone,
refer to "Doors" in "Getting To Know
Your Vehicle" in your Owner’s Manua
for further information.
• Push the lock button on the key fob.
3. If any doors are open, close them.
NOTE:
• Once the security system is armed, it re-
mains in that state until you disarm it by
following either of the disarming proce-
dures described. If a power loss occurs
after arming the system, you must disarm
the system after restoring power to prevent
alarm activation.
• The ultrasonic intrusion sensor (motion de-
tector) actively monitors your vehicle every
time you arm the security system. If you
prefer, you can turn off the ultrasonic intru-
sion sensor when arming the security sys-
tem. To do so, push the lock button on the
key fob five times within five seconds of
arming the system (while the Vehicle Secu-
rity Light is flashing rapidly).

To Disarm The System
The vehicle security alarm can be disarmed
using any of the following methods:
• Push the unlock button on the key fob.
• Grasp the passive entry door handle to
unlock the door, refer to "Doors" in "Getting
To Know Your Vehicle" in your Owner’s
Manual for further information).
• Cycle the vehicle ignition system out of the
OFF position.
– For vehicles equipped with Keyless
Enter-N-Go — Passive Entry, push the
Start/Stop ignition button (requires at
least one valid key fob in the vehicle).
– For vehicles not equipped with Keyless
Enter-N-Go — Passive Entry, insert a
valid Integrated Vehicle Key into the
ignition switch and turn the key to the
ON position.
NOTE:
• The driver's door key cylinder and the lift-
gate button on the key fob cannot arm or
disarm the vehicle security alarm.
• The vehicle security alarm remains armed
during power liftgate entry. Pushing theliftgate button will not disarm the vehicle
security alarm. If someone enters the ve-
hicle through the liftgate and opens any
door the alarm will sound.
• When the vehicle security alarm is armed,
the interior power door lock switches will
not unlock the doors.
• The ultrasonic intrusion sensor (motion de-
tector) actively monitors your vehicle every
time you arm the security system. If you
prefer, you can turn off the ultrasonic intru-
sion sensor when arming the security sys-
tem. To do so, push the lock button on the
key fob five times within five seconds of
arming the system (while the vehicle secu-
rity light is flashing rapidly).
The vehicle security alarm is designed to
protect your vehicle; however, you can create
conditions where the system will give you a
false alarm. If one of the previously described
arming sequences has occurred, the vehicle
security alarm will arm regardless of whether
you are in the vehicle or not. If you remain in
the vehicle and open a door, the alarm will
sound. If this occurs, disarm the vehicle
security alarm.If the vehicle security alarm is armed and the
battery becomes disconnected, the vehicle
security alarm will remain armed when the
battery is reconnected; the exterior lights will
flash, the horn will sound. If this occurs,
disarm the vehicle security alarm.

WARNING!
During power operation, personal injury or
cargo damage may occur. Ensure the lift-
gate travel path is clear. Make sure the
liftgate is closed and latched before driv-
ing away.NOTE:
• The liftgate will not power open or close if
the gear selector is in gear or the vehicle
speed is above 0 mph (0 km/h).
• If anything obstructs the power liftgate
while it is closing or opening, the liftgate
will automatically reverse to the closed or
open position, provided it meets sufficient
resistance.
• There are pinch sensors attached to the
side of the liftgate opening. Light pressure
anywhere along these strips will cause the
liftgate to return to the open position.
• If the power liftgate encounters multiple
obstructions within the same cycle, the
system will automatically stop. If this oc-
curs, the liftgate must be opened or closed
manually.
• The power liftgate will not operate in tem-
peratures below −22° F (−30° C) or tem-
peratures about 150° F (65° C). Be sure to
remove any buildup of snow or ice from the
liftgate before pushing any of the power
liftgate switches.• If the liftgate is left open for an extended
period of time, the liftgate may need to be
closed manually to reset power liftgate
functionality.
• Gas props support the liftgate in the open
position. However, because the gas pres-
sure drops with temperature, it may be
necessary to assist the props when opening
the liftgate in cold weather.
• Before driving off, check the instrument
cluster for a liftgate or door open message
or warning indicator. Failure to do this
could result in unintentionally leaving the
liftgate open while driving.
• If your liftgate is power closing and you put
the vehicle in gear, the liftgate will continue
to power close. However, vehicle movement
may result in a detection of an obstruction.
• If the electronic liftgate release handle is
pushed with the power liftgate is opening,
the liftgate motor will disengage to allow
manual operation.
• If the electronic liftgate release handle is
pushed while the power liftgate is closing,
the liftgate will reverse to the full open
position.

flash for approximately one minute and then
remain continuously illuminated. This se-
quence will continue upon subsequent ve-
hicle start-ups as long as the malfunction
exists. When the malfunction indicator is
illuminated, the system may not be able to
detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of
reasons, including the installation of replace-
ment or alternate tires or wheels on the ve-
hicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunc-
tion telltale after replacing one or more tires
or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels
allow the TPMS to continue to function
properly.
CAUTION!
The TPMS has been optimized for the
original equipment tires and wheels.

market wheels can cause sensor damage.
Using aftermarket tire sealants may cause
the Tire Pressure Monitoring System
(TPMS) sensor to become inoperable. Af-
ter using an aftermarket tire sealant it is
recommended that you take your vehicle
to your authorized dealer to have your
sensor function checked.
— Towing Hook Breakdown Warning

This light illuminates when there is a failure
with the tow hook. Contact your authorized
dealer for service.
— Vehicle Security Warning Light
This telltale will illuminate when the vehicle
security alarm system has detected an at-
tempt was made to break into the vehicle.
Yellow Indicator Lights
— 4WD Lock Indicator Light
This light alerts the driver that the vehicle is
in the four-wheel drive LOCK mode. The front
and rear driveshafts are mechanically locked
together, forcing the front and rear wheels to
rotate at the same speed.
Refer to “Four-Wheel Drive Operation” in
“Starting And Operating” for further informa-
tion on four-wheel drive operation and proper
use.
— 4WD Low Indicator Light — If
Equipped
This light alerts the driver that the vehicle is
in the four-wheel drive LOW mode. The front
and rear driveshafts are mechanically locked
together forcing the front and rear wheels to
rotate at the same speed. Low range provides
a greater gear reduction ratio to provide in-
creased torque at the wheels.
Refer to “Four-Wheel Drive Operation — If
Equipped” in “Starting And Operating” for
further information on four-wheel drive op-
eration and proper use.

WARNING!
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.
Electronic Stability Control (ESC)
This system enhances directional control and
stability of the vehicle under various driving
conditions. ESC corrects for oversteering or
understeering of the vehicle by applying the
brake of the appropriate wheel(s) to assist in
counteracting the oversteer or understeer
condition. Engine power may also be reduced
to help the vehicle maintain the desired path.
ESC uses sensors in the vehicle to determine
the vehicle path intended by the driver and
compares it to the actual path of the vehicle.
When the actual path does not match the
intended path, ESC applies the brake of the
appropriate wheel to assist in counteracting
the oversteer or understeer condition.
• Oversteer — when the vehicle is turning
more than appropriate for the steering
wheel position.• Understeer — when the vehicle is turning
less than appropriate for the steering wheel
position.
The “ESC Activation/Malfunction Indicator
Light” located in the instrument cluster will
start to flash as soon as the ESC system
becomes active. The “ESC Activation/
Malfunction Indicator Light” also flashes
when the TCS is active. If the “ESC
Activation/Malfunction Indicator Light” be-
gins to flash during acceleration, ease up on
the accelerator and apply as little throttle as
possible. Be sure to adapt your speed and
driving to the prevailing road conditions.
WARNING!
•Electronic Stability Control (ESC) cannot
prevent the natural laws of physics from
acting on the vehicle, nor can it increase
the traction afforded by prevailing road con-
ditions. ESC cannot prevent accidents, in-
cluding those resulting from excessive
speed in turns, driving on very slippery
surfaces, or hydroplaning. ESC also cannot
prevent accidents resulting from loss of
WARNING!
vehicle control due to inappropriate driver
input for the conditions. Only a safe, atten-
tive, and skillful driver can prevent acci-
dents. The capabilities of an ESC equipped
vehicle must never be exploited in a reck-
less or dangerous manner which could jeop-
ardize the user’s safety or the safety of
others.
• Vehicle modifications, or failure to prop-
erly maintain your vehicle, may change
the handling characteristics of your ve-
hicle, and may negatively affect the per-
formance of the ESC system. Changes to
the steering system, suspension, brak-
ing system, tire type and size or wheel
size may adversely affect ESC perfor-
mance. Improperly inflated and un-
evenly worn tires may also degrade ESC
performance. Any vehicle modification
or poor vehicle maintenance that re-
duces the effectiveness of the ESC sys-
tem can increase the risk of loss of
vehicle control, vehicle rollover, per-
sonal injury and death.

Rain Brake Support (RBS)
Rain Brake Support may improve braking
performance in wet conditions. It will periodi-
cally apply a small amount of brake pressure
to remove any water buildup on the front
brake rotors. It functions when the wind-
shield wipers are in LO or HI speed. When
Rain Brake Support is active, there is no
notification to the driver and no driver inter-
action is required.
Ready Alert Braking (RAB)
Ready Alert Braking may reduce the time
required to reach full braking during emer-
gency braking situations. It anticipates when
an emergency braking situation may occur by
monitoring how fast the throttle is released by
the driver. The EBC will prepare the brake
system for a panic stop.
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 automatically
once an excessively swaying trailer is recog-
nized.NOTE:
TSC cannot stop all trailers from swaying.
Always use caution when towing a trailer and
follow the trailer tongue weight recommenda-
tions. Refer to “Trailer Towing” in “Starting
And Operating” for further information.
When TSC is functioning, the “ESC
Activation/Malfunction Indicator Light” will
flash, the engine power may be reduced and
you may feel the brakes being applied to
individual wheels to attempt to stop the
trailer from swaying. TSC is disabled when
the ESC system is in the “Partial Off” or “Full
Off” modes.
WARNING!
If TSC activates while driving, slow the
vehicle down, stop at the nearest safe
location, and adjust the trailer load to
eliminate trailer sway.
AUXILIARY DRIVING
SYSTEMS
Blind Spot Monitoring (BSM) — If
Equipped
The Blind Spot Monitoring (BSM) system
uses two radar-based sensors, located inside
the rear bumper fascia, to detect highway
licensable vehicles (automobiles, trucks, mo-
torcycles, etc.) that enter the blind spot
zones from the rear/front/side of the vehicle.
Rear Detection Zones
85

When the vehicle is started, the BSM warning
light will momentarily illuminate in both out-
side rear view mirrors to let the driver know
that the system is operational. The BSM
system sensors operate when the vehicle is in
any forward gear or REVERSE and enters
stand-by mode when the vehicle is in PARK.
The BSM detection zone covers approxi-
mately one lane width on both sides of the
vehicle 12 ft (3.8 m). The zone length starts
at the outside mirror and extends approxi-
mately 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 reaches approxi-
mately 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 detection 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 traileror other object (i.e., bicycle, sports equip-
ment) extends beyond the side of your ve-
hicle, this may result in the BSM warning
light remaining illuminated the entire time
the vehicle is in a forward gear. It may be
necessary to deactivate the BSM system
manually to avoid miss-detection. Refer to
“Uconnect Settings” in “Multimedia” in
the Owner’s Manual for further information.
The area on the rear fascia where the radar
sensors are located must remain free of snow,
ice, and dirt/road contamination so that the
BSM system can function properly. Do not
block the area of the rear fascia where the
radar sensors are located with foreign objects
(bumper stickers, bicycle racks, etc.)
The BSM system will provide a visual alert in
the appropriate side view mirror based on a
detected object. If the turn signal is then
activated, and it corresponds to an alert pres-
ent on that side of the vehicle, an audible
chime will also be sounded. Whenever a turn
signal and detected object are present on the
same side at the same time, both the visual
and audio alerts will be issued. In addition to
the audible alert the radio (if on) will also be
muted.The BSM system monitors the detection zone
from three different entry points (side, rear,
front) while driving to see if an alert is nec-
essary. The BSM system will issue an alert
during these types of zone entries.
Entering From The Side
Vehicles that move into your adjacent lanes
from either side of the vehicle.
Entering From The Rear
Vehicles that come up from behind your ve-
hicle on either side and enter the rear detec-
tion zone with a relative speed of less than
30 mph (48 km/h).
BSM Warning Light
SAFETY
86

Overtaking Traffic
If you pass another vehicle slowly with a
relative speed less than 10 mph (16 km/h)
and the vehicle remains in the blind spot for
approximately 1.5 seconds, the warning light
will be illuminated. If the difference in speed
between the two vehicles is greater than
10 mph (16 km/h), the warning light will not
illuminate.
The BSM system is designed not to issue an
alert on stationary objects such as guardrails,
posts, walls, foliage, berms, etc. However,
occasionally the system may alert on such
objects. This is normal operation and your
vehicle does not require service.
The BSM system will not alert you of objects
that are traveling in the opposite direction of
the vehicle in adjacent lanes.NOTE:
The BSM system may experience drop outs
(blinking on and off) in the side mirror LED
icons while a motorcycle, or any small target,
remains behind the front door for an ex-
tended period of time (longer than a couple of
seconds).
WARNING!
The Blind Spot Monitoring system is only
an aid to help detect objects in the blind
spot zones. The BSM system is not de-
signed to detect pedestrians, bicyclists, or
animals. Even if your vehicle is equipped
with the BSM system, always check your
vehicle’s mirrors, glance over your shoul-
der, and use your turn signal before chang-
ing lanes. Failure to do so can result in
serious injury or death.
Rear Cross Path (RCP)
The Rear Cross Path (RCP) feature is in-
tended to aid the driver when backing out of
parking spaces where their vision of oncom-ing vehicles may be blocked. Proceed slowly
and cautiously out of the parking space until
the rear end of the vehicle is exposed. The
RCP system will then have a clear view of the
cross traffic and if an oncoming vehicle is
detected, alert the driver.
RCP monitors the rear detection zones on
both sides of the vehicle, for objects that are
moving toward the side of the vehicle with a
minimum speed of approximately 3 mph
(5 km/h), to objects moving a maximum of
approximately 20 mph (32 km/h), such as in
parking lot situations.
NOTE:
In a parking lot situation, oncoming vehicles
can be obscured by vehicles parked on either
side. If the sensors are blocked by other
structures or vehicles, the system will not be
able to alert the driver.
When RCP is on and the vehicle is in RE-
VERSE, the driver is alerted using both the
visual and audible alarms, including reduc-
ing the radio volume.
