158STARTING AND OPERATING
NOTE:
The driver is always responsible for controlling the
vehicle, responsible for any surrounding objects, and
must intervene as required.
 The system is provided to assist the driver and not to
substitute the driver.
 During a semi-automatic maneuver, if the driver
touches the steering wheel after being instructed to
remove their hands from the steering wheel, the
system will cancel, and the driver will be required to
manually complete the parking maneuver.
 The system may not work in all conditions
(e.g. environmental conditions such as heavy rain,
snow, etc., or if searching for a parking space that has
surfaces that will absorb the ultrasonic sensor waves).
 New vehicles from the dealership must have at least
30 miles (48 km) accumulated before the ParkSense
Active Park Assist system is fully calibrated and
performs accurately. This is due to the system’s
dynamic vehicle calibration to improve the perfor -
mance of the feature.
 The driver must control the vehicle’s brakes. The auto -
matic emergency braking feature is NOT intended to
substitute for the driver during REVERSE maneuvers.ENABLING AND DISABLING THE

160STARTING AND OPERATING
The system may then instruct the driver to wait for steering
to complete before then instructing to check surroundings
and move backward.

Move Backward Into Parallel Parking Space
Move Backward Into Perpendicular Parking Space

The system may instruct several more gear shifts
(DRIVE and REVERSE), with hands off of the steering
wheel, before instructing the driver to check surroundings
and complete the parking maneuver. When the vehicle is in the parking position, the maneuver
is complete and the driver will be instructed to check the
vehicle's parking position, then shift the vehicle into PARK.
The message "Active ParkSense Complete - Check Parking
Position" will be displayed momentarily.
NOTE:

It is the driver's responsibility to use the brake and
accelerator during the semi-automatic parking
maneuver.
 It is the driver's responsibility to use the brake and stop
the vehicle. The driver should check their surroundings
and be prepared to stop the vehicle either when
instructed to, or when driver intervention is required.
 When the system instructs the driver to remove their
hands from the steering wheel, the driver should check
their surroundings and begin to back up slowly.
 The ParkSense Active Park Assist system will allow a
maximum of eight shifts between DRIVE and REVERSE.
If the maneuver cannot be completed within eight
shifts, the system will cancel and the instrument
cluster display will instruct the driver to complete the
maneuver manually.
 The system will cancel the maneuver if the vehicle
speed exceeds 5 mph (7 km/h) during active steering
guidance into the parking space. The system will
provide a warning to the driver at 3 mph (5 km/h) that
tells them to slow down. The driver is then responsible
for completing the maneuver if the system is canceled.
 If the system is canceled during the maneuver for any
reason, the driver must take control of the vehicle.
WARNING!
Drivers must be careful when performing parallel or
perpendicular parking maneuvers even when using the
ParkSense Active Park Assist system. Always check
carefully behind and in front of your vehicle, look
behind and in front of you, and be sure to check for
pedestrians, animals, other vehicles, obstructions, and
blind spots before backing up and moving forward. You
are responsible for safety and must continue to pay
attention to your surroundings. Failure to do so can
result in serious injury or death.
CAUTION!
The ParkSense Active Park Assist system is only a
parking aid and it is unable to recognize every
obstacle, including small obstacles. Parking curbs
might be temporarily detected or not detected at all.
Obstacles located above or below the sensors’ field
of view will not be detected when they are in close
proximity.
 The vehicle must be driven slowly when using the
ParkSense Active Park Assist system in order to be
able to stop in time when an obstacle is detected.
It is recommended that the driver looks over his/her
shoulders when using the ParkSense Active Park
Assist system.

264SAFETY
Electronic Roll Mitigation (ERM)
The ERM 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, striking objects or other vehicles.
Electronic Stability Control (ESC)
ESC 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 counteract these
conditions. Engine power may also be reduced to help the
vehicle maintain the desired path.
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.
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.
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 begins 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!
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 rollovers, especially those that involve leaving the
roadway or striking objects or other vehicles. 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.
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 conditions. ESC cannot prevent accidents,
including those resulting from excessive speed in
turns, driving on very slippery surfaces, or hydro -
planing. ESC also cannot prevent accidents resulting
from loss of vehicle control due to inappropriate
driver input for the conditions. Only a safe, attentive,
and skillful driver can prevent accidents. The capabil -
ities of an ESC equipped vehicle must never be
exploited in a reckless or dangerous manner which
could jeopardize the user’s safety or the safety of
others.
 Vehicle modifications, or failure to properly maintain
your vehicle, may change the handling characteris -
tics 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.

Driver Override
The driver may override SSC activation with throttle or
brake application at any time.
Deactivating SSC
SSC will be deactivated but remain available if any of the
following conditions occur:
The driver overrides SSC set speed with throttle or
brake application.
 The vehicle speed exceeds 20 mph (32 km/h) but
remains below 40 mph (64 km/h).
 The vehicle is shifted into PARK.
Disabling SSC
SSC will deactivate and be disabled if any of the following
conditions occur:
 The driver pushes the SSC switch.
 The driveline is shifted out of the 4WD Low.
 The parking brake is applied.
 The driver door opens.
 The vehicle is driven greater than 20 mph (32 km/h)
for greater than 70 seconds.
 The vehicle is driven greater than 40 mph (64 km/h).
SSC will exist immediately. Feedback To The Driver
The instrument cluster has an SSC icon and the SSC
switch has a lamp which offers feedback to the driver
about the state SSC is in.

The cluster icon and switch lamp will illuminate and
remain on solid when SSC is enabled or activated.
These are the normal operating conditions for SSC.
 The cluster icon and switch lamp will flash for several
seconds then extinguish when the driver pushes the
SSC switch but enabled conditions are not met.
 The cluster icon and switch lamp will flash for several
seconds then extinguish when SSC disables due to
excess speed.
 The cluster icon and switch lamp will flash then extin -
guish when SSC deactivates due to overheated brakes.
Traction Control System (TCS)
The TCS monitors the amount of wheel spin of each of the
driven wheels. If wheel spin is detected, the TCS may apply
brake pressure to the spinning wheel(s) and/or reduce
engine power to provide enhanced acceleration and
stability. A feature of the TCS, Brake Limited Differential (BLD)
functions similarly to a limited slip differential and controls
the wheel spin across a driven axle. If one wheel on a
driven axle is spinning faster than the other, the system
will apply the brake of the spinning wheel. This will allow
more engine torque to be applied to the wheel that is not
spinning. BLD may remain enabled even if TCS and
Electronic Stability Control (ESC) are in reduced modes.
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.
NOTE:TSC cannot stop all trailers from swaying. Always use
caution when towing a trailer and follow the trailer tongue
weight recommendations
Úpage 173.
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!
SSC is only intended to assist the driver in controlling
vehicle speed when driving in off road conditions. The
driver must remain attentive to the driving conditions
and is responsible for maintaining a safe vehicle speed.
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) —
I
F EQUIPPED
BSM uses two radar sensors, located inside the taillights,
to detect highway licensable vehicles (automobiles,
trucks, motorcycles, etc.) that enter the blind spot zones
from the rear/front/side of the vehicle.

Rear Detection Zones

When the vehicle is started, the BSM Warning Light will
momentarily illuminate in both outside rearview mirrors to
let the driver know that the system is operational. The
BSM system sensors operate when the vehicle is in any
forward gear and enters standby mode when the vehicle is
in PARK. The BSM detection zone covers approximately one lane
width on both sides of the vehicle 12 ft (3.8 m). The zone
length starts at the outside rearview mirror and extends
approximately 10 ft (3 m) beyond the rear fascia/bumper
of the vehicle. The BSM system monitors the detection
zones on both sides of the vehicle when the vehicle speed
reaches 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
detection zones.
 BSM may experience dropouts (blinking on and off) of
the side mirror warning indicator lights when a motor -
cycle or any small object remains at the side of the
vehicle for extended periods of time (more than a
couple of seconds).
The BSM system can become blocked if snow, ice, mud, or
other road contaminations accumulate on the rear fascia/
bumper where the radar sensors are located. The system
may also detect blockage if the vehicle is operated in
areas with extremely low radar returns such as a desert or
parallel to a large elevation drop. If blockage is detected,
a “Blind Spot Temporarily Unavailable, Wipe Rear
Corners” message will display in the cluster, both mirror
lights will illuminate, and BSM and RCP alerts will not
occur. This is normal operation. The system will
automatically recover and resume function when the
condition clears. To minimize system blockage, do not
block the area of the rear fascia/bumper where the radar
sensors are located with foreign objects (bumper stickers,
bicycle racks, etc.) and keep it clear of road
contaminations.

Radar Sensor Locations

If the system detects degraded performance due to
contamination or foreign objects, a message will warn you
of a blocked sensor and the warning indicators in side
view mirrors will be on. The warning indicators will remain
illuminated until blockage clearing conditions are met.
First clear the taillights around the sensors of the
blockage. After removing the blockage, the following
procedure can be used to reset the system:
Cycle the ignition from ON to OFF and then back ON.
If the blockage message is still present after cycling the
ignition and driving in traffic, check again for a blockage.
The system may also detect a blockage if the vehicle is
operated in areas with extremely low radar returns such as
a desert or parallel to a large elevation drop.

272SAFETY
When RCP is on and the vehicle is in REVERSE (R), the
driver is alerted using both the visual and audible alarms,
including reducing the radio volume.
NOTE:In a parking lot situation, oncoming vehicles can be
blocked 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.
Blind Spot Modes
Blind Spot has three selectable modes of operation that
are available in the Uconnect system.
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, RCP, or Trailer
Merge Assist 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 — If Equipped
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.
NOTE:When Trailer Merge Assist is activated, Rear Cross Path is
disabled.
Trailer Merge Assist consists of three sub functions:

Automatic Trailer Detection
 Trailer Length Detection
 Trailer Merge Warning

Blind Spot Zones With Trailer Merge Assist

WARNING!
Rear Cross Path Detection (RCP) is not a backup aid
system. It is intended to be used to help a driver detect
an oncoming vehicle in a parking lot situation. Drivers
must be careful when backing up, even when using
RCP. Always check carefully behind your vehicle, look
behind you, and be sure to check for pedestrians,
animals, other vehicles, obstructions, and blind spots
before backing up. Failure to do so can result in serious
injury or death.

SAFETY273
Automatic Trailer Detection
There are two modes of operation for the detection of the
trailer length:
Automatic Mode — When “Auto Mode” is selected, the
system will use the blind spot sensors to automatically
determine the presence and length of a trailer. The
presence of a trailer will be detected using the blind
spot radar within 90 seconds of forward movement of
the vehicle. The vehicle must be moving above 6 mph
(10 km/h) to activate the feature. Once the trailer has
been detected, the system will default to the maximum
blind spot zone until the length has been verified. You
will see “Auto” in the instrument panel cluster .
 Maximum Mode — When “Max Mode” is selected, the
system will default to the maximum blind spot zone
regardless of what size trailer is attached .
NOTE:Selected setting is stored when the ignition is placed in the
OFF position. To change this setting, it must be selected
through the Uconnect Settings
Úpage 191.
Trailer Length Detection
Once the trailer presence has been established, the trailer
length will be established (by making a 90 degree turn)
and then the trailer length category (example 10-20 ft
(3 m to 6 m)) will be displayed. This can take up to
30 seconds after completing the turn.
NOTE:During the same ignition cycle, if the vehicle is at a
standstill for a minimum of 90 seconds, a new “trailer
detection request” is enabled by the system once the
vehicle resumes motion.
The maximum trailer length supported by the Trailer
Merge Assist feature is 39.5 ft (12 m). Trailer length is
considered the forward most portion of the trailer hitch to
the rearward most portion of the body, fascia/bumper, or
ramp of the trailer.
The maximum width supported by the Trailer Merge Assist
feature is 8.5 ft (2.59 m). Trailer width is measured at the
widest portion of the trailer and may include wheels, tires,
finders, or rails.
NOTE:Fifth wheel or gooseneck trailers are not supported by
Trailer Merge Assist.
NOTE:The ability to detect a trailer may be degraded in crowded
or busy environments. Busy parking lots, narrow areas
surrounded with trees, or any other crowded area may
prevent the radar sensors from being able to adequately
detect the trailer. The system will try to detect a trailer at
every ignition cycle or 90 seconds of standstill.

Trailer Length Detection

Trailer length will be identified and placed into one of the
following categories:
 Trailer length up to 10 ft (3 m) — Blind spot zone will be
adjusted to 10 ft (3 m) .
 Trailer length between 10 ft to 20 ft
(3 m to 6 m) — Blind spot zone will be adjusted to
20 ft (6 m) .
 Trailer length between 20 ft to 30 ft
(6 m to 9 m) — Blind spot zone will be adjusted to
30 ft (9 m) .
 Trailer length between 30 ft and 39.5 ft
(9 m to 12 m) — Blind spot zone will be adjusted to
Max distance .

274SAFETY
NOTE:Trailer length is determined within +/- 3 ft (1 m) of actual
length. Trailers that are the same size as the category
limit, 10/20/30 ft (3/6/9 m), could be subject to being
placed in the category above or below the correct one.
Trailer Merge Warning
Trailer Merge Warning is the extension of the blind spot
function to cover the length of the trailer, plus a safety
margin, to warn the driver when there is a vehicle in the
adjacent lane. The driver is alerted by the illumination of
the BSM Warning Light located in the outside mirror on the
side the other vehicle is detected on. In addition, an
audible (chime) alert will be heard and radio volume will
be reduced
Úpage 272.
NOTE:
The Trailer Merge Alert system DOES NOT alert the
driver about rapidly approaching vehicles that are
outside the detection zones.
 The Blind Spot Monitoring (BSM) system may experi -
ence drop outs (blinking on and off) of the side mirror
warning indicator lights when a motorcycle or any small
object remains at the side of the vehicle for extended
periods of time (more than a couple of seconds).
 Crowded areas such as parking lots, neighborhoods,
etc. may lead to an increased amount of false alerts.
This is normal operation.
FORWARD COLLISION WARNING (FCW)
W
ITH MITIGATION — IF EQUIPPED
FCW with Mitigation provides the driver with audible
warnings, visual warnings (within the instrument cluster
display), and may apply a brake jerk to warn the driver
when it detects a potential frontal collision. The warnings
and limited braking are intended to provide the driver with
enough time to react, avoid or mitigate the potential
collision.
NOTE:FCW monitors the information from the forward looking
sensors as well as the Electronic Brake Controller (EBC), to
calculate the probability of a forward collision. When the
system determines that a forward collision is probable, the
driver will be provided with audible and visual warnings as
well as a possible brake jerk warning. If the driver does not take action based upon these
progressive warnings, then the system will provide a
limited level of active braking to help slow the vehicle and
mitigate the potential forward collision. If the driver reacts
to the warnings by braking and the system determines
that the driver intends to avoid the collision by braking but
has not applied sufficient brake force, the system will
compensate and provide additional brake force as
required.
If a FCW with Mitigation event begins at a speed below
32 mph (52 km/h), the system may provide the maximum
braking possible to mitigate the potential forward
collision. If the Forward Collision Warning with Mitigation
event stops the vehicle completely, the system will hold
the vehicle at standstill for two seconds and then release
the brakes.

FCW Message

WARNING!
The Blind Spot Monitoring system is only an aid to help
detect objects in the blind spot zones. The BSM system
is not designed 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 shoulder, and use your turn signal before
changing lanes. Failure to do so can result in serious
injury or death.

23_DT_OM_EN_USC_t.book Page 274

SAFETY277
TIRE PRESSURE MONITORING SYSTEM
(TPMS)
TPMS will warn the driver of a low tire pressure based on
the vehicle recommended cold placard pressure.
NOTE:The TPMS Warning Light will illuminate in the instrument
cluster and a chime will sound when tire pressure is low in
one or more of the four active road tires. In addition, the
instrument cluster will display a graphic showing the
pressure values of each tire with the low tire pressure
values in a different color, or the Uconnect radio will
display a TPMS message; when this occurs you must
increase the tire pressure to the recommended cold
placard pressure in order for the TPMS Warning Light to
turn off.
The tire pressure will vary with temperature by about 1 psi
(7 kPa) for every 12°F (6.5°C). This means that when the
outside temperature decreases, the tire pressure will
decrease. Tire pressure should always be set based on
cold inflation tire pressure. This is defined as the tire
pressure after the vehicle has not been driven for at least
three hours, or driven less than 1 mile (1.6 km) after a
three hour period. The cold tire inflation pressure must not
exceed the maximum inflation pressure molded into the
tire sidewall. The tire pressure will also increase as the
vehicle is driven — this is normal and there should be no
adjustment for this increased pressure.
See
Úpage 370 on how to properly inflate the vehicle’s
tires. The TPMS will warn the driver of a low tire pressure if the
tire pressure falls below the low-pressure warning limit for
any reason, including low temperature effects and natural
pressure loss through the tire
Úpage 402.
The TPMS will continue to warn the driver of low tire
pressure as long as the condition exists, and will not turn
off until the tire pressure is at or above the recommended
cold placard pressure. Once the low TPMS Warning Light
illuminates, increase the tire pressure to the
recommended cold placard pressure in order for the
TPMS Warning Light to turn off. The system will
automatically update and the TPMS Warning Light will turn
off once the system receives the updated tire pressures.
The vehicle may need to be driven for up to 20 minutes
above 15 mph (24 km/h) in order for the TPMS to receive
this information.
NOTE:When filling warm tires, the tire pressure may need to be
increased up to an additional 4 psi (28 kPa) above the
recommended cold placard pressure in order to turn the
TPMS Warning Light off.
For example, your vehicle may have a recommended cold
(parked for more than three hours) placard pressure of
30 psi (207 kPa). If the ambient temperature is 68°F
(20°C) and the measured tire pressure is 27 psi
(186 kPa), a temperature drop to 20°F (-7°C) will
decrease the tire pressure to approximately 23 psi
(158 kPa). This tire pressure is sufficiently low enough
to turn on the TPMS Warning Light. Driving the vehicle may cause the tire pressure to rise to
approximately 27 psi (186 kPa), but the TPMS Warning
Light will still be on. In this situation, the TPMS Warning
Light will turn off only after the tires are inflated to the
vehicle’s recommended cold placard pressure value.
CAUTION!

The TPMS has been optimized for the original equip -
ment tires and wheels. TPMS pressures and warning
have been established for the tire size equipped on
your vehicle. Undesirable system operation or sensor
damage may result when using replacement equip -
ment that is not of the same size, type, and/or style.
Aftermarket wheels can cause sensor damage.
 Using aftermarket tire sealants may cause the Tire
Pressure Monitoring System (TPMS) sensor to
become inoperable. After using an aftermarket tire
sealant it is recommended that you take your vehicle
to an authorized dealership to have your sensor func -
tion checked.
 After inspecting or adjusting the tire pressure always
reinstall the valve stem cap. This will prevent mois -
ture and dirt from entering the valve stem, which
could damage the TPMS sensor.
