Warning Light
The warning light switches on and a

Should one or more tires be in the condition
mentioned above, the display will show the indi -
cations corresponding to each tire. Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. If your
vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation
pressure label, you should determine the
proper tire inflation pressure for those tires.
As an added safety feature, your vehicle has
been equipped with a Tire Pressure Monitoring
System (TPMS) that illuminates a low tire pres
-
sure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when
the low tire pressure telltale illuminates, you
should stop and check your tires as soon as
possible, and inflate them to the proper pres -
sure. Driving on a significantly under-inflated
CAUTION!
Do not continue driving with one or more flat
tires as handling may be compromised. Stop
the vehicle, avoiding sharp braking and
steering. If a tire puncture occurs, repair
immediately using the dedicated tire repair
kit and contact an authorized dealer as soon
as possible.

ESC Operating Modes
NOTE:
Depending upon model and mode of operation,
the ESC system may have multiple operating
modes. ESC On
This is the normal operating mode for the ESC.
Whenever the vehicle is started, the ESC system
will be in this mode. This mode should be used
for most driving conditions. Alternate ESC
modes should only be used for specific reasons
as noted in the following paragraphs.
Partial Off
The “Partial Off” mode is intended for times
when a more spirited driving experience is
desired. This mode may modify TCS and ESC
thresholds for activation, which allows for more
wheel spin than normally allowed. This mode
may be useful if the vehicle becomes stuck.
To enter the “Partial Off” mode, momentarily
push the “ESC OFF” switch and the “ESC OFF
Indicator Light” will illuminate. To turn the ESC
on again, momentarily push the “ESC OFF”
switch and the “ESC OFF Indicator Light” will
turn off.
NOTE:
For vehicles with multiple partial ESC modes, a
momentary button push will toggle the ESC
mode. Multiple momentary button pushes may
be required to return to ESC On.
Full Off — If Equipped
This mode is intended for off-highway or
off-road use only and should not be used on any
public roadways. In this mode, TCS and ESC
features are turned off. To enter the “Full Off”
mode, push and hold the “ESC OFF” switch for
five seconds while the vehicle is stopped with
the engine running. After five seconds, a chime
will sound, the “ESC OFF Indicator Light” will illu
-
minate, and the “ESC OFF” message will display
in the instrument cluster. To turn ESC on again,
momentarily push the “ESC OFF” switch.
Vehicle modifications, or failure to properly
maintain your vehicle, may change the
handling characteristics of your vehicle,
and may negatively affect the performance
of the ESC system. Changes to the steering
system, suspension, braking system, tire
type and size or wheel size may adversely
affect ESC performance. Improperly
inflated and unevenly worn tires may also
degrade ESC performance. Any vehicle
modification or poor vehicle maintenance
that reduces the effectiveness of the ESC
system can increase the risk of loss of
vehicle control, vehicle rollover, personal
injury and death.
WARNING! (Continued)WARNING!
When in “Partial Off” mode, the TCS func -
tionality of ESC, (except for the limited slip
feature described in the TCS section), has
been disabled and the “ESC Off Indicator
Light” will be illuminated. When in “Partial
Off” mode, the engine power reduction
feature of TCS is disabled, and the
enhanced vehicle stability offered by the
ESC system is reduced.
Trailer Sway Control (TSC) is disabled when
the ESC system is in the “Partial Off” mode.

Disabling And Enabling HSA
This feature can be turned on or turned off. To
change the current setting, proceed as follows:
If disabling HSA using your instrument cluster
display, refer to “Instrument Cluster Display”
in “Getting To Know Your Instrument Panel”
for further information.
If disabling HSA using Uconnect Settings,
refer to “Uconnect Settings” in “Multimedia”
for further information.
For vehicles not equipped with an instrument
cluster display, perform the following steps:

1. Center the steering wheel (front wheels pointing straight 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. Place the ignition in 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 pres -
sure 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 resuming acceleration, manually acti -
vate the trailer brake or apply more vehicle
brake pressure prior to releasing 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 trans -
mission in PARK.
Failure to follow these warnings can result
in a collision or serious personal injury.

Modes Of Operation
Three selectable modes of operation are avail -
able in the Uconnect System.
Refer to “Uconnect Settings” in “Multimedia”
for further information.
Blind Spot Alert Lights Only
When operating in Blind Spot Alert mode, the
BSM system will provide a visual alert in the
appropriate side view mirror based on a
detected object. However, when the system is
operating in Rear Cross Path (RCP) mode, the
system will respond with both visual and
audible alerts when a detected object is
present. Whenever an audible alert is
requested, the radio is muted.
Blind Spot Alert Lights/Chime
When operating in Blind Spot Alert Lights/
Chime mode, 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
present 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
audible alerts will be issued. In addition to the
audible alert the radio (if on) will also be muted. NOTE:
Whenever an audible alert is requested by the
BSM system, the radio is also muted.
When the system is in RCP, the system shall
respond with both visual and audible alerts
when a detected object is present. Whenever
an audible alert is requested, the radio is also
muted. Turn/hazard signal status is ignored;
the RCP state always requests the chime.
Blind Spot Alert Off
When the BSM system is turned off there will be
no visual or audible alerts from either the BSM
or RCP systems.
NOTE:
The BSM system will store the current operating
mode when the vehicle is shut off. Each time
the vehicle is started the previously stored
mode will be recalled and used.
Trailer Merge Assist
NOTE:
When Trailer Merge Assist is activated, Rear
Cross Path is disabled.
NOTE:
When a trailer with an electric brake is
connected to the vehicle, the instrument cluster
display will provide a menu to allow a selection
of the trailer type. There will be two options
provided: Conventional and Goose/Fifth Wheel.
Goose/Fifth Wheel Trailer is incompatible and
when selected, the BSM system will disable
until the trailer is disconnected. If the wrong
option is selected, the system can be reset by
either disconnecting and reconnecting the
trailer harness connector or disabling then
re-enabling the Blind Spot Monitoring System in
the customer settings in the Uconnect. This will
prompt the trailer selection menu again to allow
for the correct selection.
Trailer Merge Assist is a function of the Blind
Spot Monitoring (BSM) system that extends the
blind spot zone to work while pulling a trailer.
Trailer Merge Assist consists of three sub func
-
tions:Automatic Trailer Detection
Trailer Length Detection
Trailer Merge Warning
