Tire Pressure Monitoring System (TPMS)
Warning Light
The warning light switches on and a message is
displayed to indicate that the tire pressure is
lower than the recommended value and/or
that slow pressure loss is occurring. In these
cases, optimal tire duration and fuel consumption may not
be guaranteed.
Should one or more tires be in the condition mentioned
previously, the display will show the indications
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 TPMS that illuminates a low tire pressure
telltale when one or more of your tires is significantly
underinflated. 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
pressure. Driving on a significantly underinflated tire
causes the tire to overheat and can lead to tire failure.
Underinflation also reduces fuel efficiency and tire tread
life, and may affect the vehicle’s handling and stopping
ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver’s responsibility to
maintain correct tire pressure, even if underinflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is not
operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale. When the
system detects a malfunction, the telltale will flash for
approximately one minute and then remain continuously
illuminated. This sequence will continue upon subsequent
vehicle 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 replacement or
alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the TPMS
malfunction 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
Úpage 252.
Towing Hook Breakdown Warning Light —
If Equipped
This light illuminates when there is a failure
with the tow hook. Contact an authorized
dealer for service.
YELLOW INDICATOR LIGHTS
4WD Low Indicator Light — If Equipped
This light alerts the driver that the vehicle is in
the 4WD 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 increased torque at the wheels
Úpage 129.
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.
CAUTION!
The TPMS has been optimized for the original
equipment 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 equipment 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 dealer to have your
sensor function checked.

122STARTING AND OPERATING
COLD WEATHER OPERATION
(B
ELOW –22°F OR −30°C)
To ensure reliable starting at these temperatures, use of
an externally powered electric engine block heater
(available from an authorized dealer) is recommended.
AFTER STARTING
The idle speed is controlled automatically, and it will
decrease as the engine warms up.
TURBOCHARGER “COOL DOWN” —
3.0L E
NGINE ONLY
The 3.0L engine is equipped with an after-run pump to
cool the turbocharger after the engine is shut off.
Depending on the type of driving and the amount of cargo,
the pump will run for up to 20 minutes after the engine
has been shut off to circulate coolant through the
turbocharger. Although the pump is rubber-mounted for
quiet operation, it is normal to hear it running during this
time.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine, and permits
quicker starts in cold weather. Connect the cord to a
standard 110-115 Volt AC electrical outlet with a
grounded, three-wire extension cord.
The engine block heater must be plugged in at least one
hour to have an adequate warming effect on the engine. The engine block heater cord is coiled and strapped right
behind the engine air cleaner filter assembly from the
manufacturer.
ENGINE BREAK-IN RECOMMENDATIONS
An initial break-in period is recommended for the
powertrain (engine, transmission, axle, etc.) in your
vehicle. Adhering to the following guidelines will contribute
to improved longevity, fuel economy, and performance.
Drive moderately during the first 100 miles (160 km).
After that, for the first 500 miles (800 km), avoid long
periods at constant speed. Varying speed, engine RPM,
and throttle position is desirable.
Avoid high performance, severe off-road, and towing for
the first 500 miles (800 km).
NOTE:A new engine may consume some oil during its first few
thousand miles (km) of operation. This should be
considered a normal part of the break-in and not inter -
preted as a problem. For engines not equipped with an oil
level sensor, please check your oil level frequently during
the break-in period. Add manufacturer-approved oil as
required
Úpage 376.
PARKING BRAKE
ELECTRIC PARK BRAKE (EPB)
Your vehicle is equipped with an EPB that offers simple
operation, and some additional features that make the
parking brake more convenient and useful.
The parking brake is primarily intended to prevent the
vehicle from rolling while parked. Before leaving the
vehicle, make sure that the parking brake is applied. Also,
be certain to leave the transmission in PARK.
You can engage the parking brake in two ways:
 Manually, by applying the EPB switch.
 Automatically, by enabling the Auto Park Brake feature
in the customer programmable features section of the
Uconnect settings.
WARNING!
Remember to disconnect the engine block heater cord
before driving. Damage to the 110-115 Volt electrical
cord could cause electrocution.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil in
the engine or damage may result. ONLY USE OILS THAT
ARE API APPROVED

STARTING AND OPERATING139
(Continued)
USING CRUISE CONTROL ON HILLS
The transmission may downshift on hills to maintain the
vehicle set speed.
The Cruise Control system maintains speed up and down
hills. A slight speed change on moderate hills is normal.
On steep hills, a greater speed loss or gain may occur so it
may be preferable to drive without Cruise Control.
To Resume Speed
To resume a previously set speed, push the RES button
and release. Resume can be used at any speed above
20 mph (32 km/h).
To Deactivate
A tap on the brake pedal, pushing the CANC button, or
normal brake pressure while slowing the vehicle will
deactivate the Cruise Control system without erasing the
set speed from memory. The following conditions will also deactivate the Cruise
Control without erasing the set speed from memory:

Vehicle parking brake is applied
 Stability event occurs
 Gear selector is moved out of DRIVE
 Engine overspeed occurs
Pushing the on/off button or placing the ignition in the OFF
position, will also erase the set speed from memory.
ADAPTIVE CRUISE CONTROL (ACC)
Adaptive Cruise Control (ACC) increases the driving
convenience provided by Cruise Control while traveling on
highways and major roadways. However, it is not a safety
system and not designed to prevent collisions. The Cruise
Control function performs differently
Úpage 138.
ACC will allow you to keep Cruise Control engaged in light
to moderate traffic conditions without the constant need
to reset your Cruise Control. ACC utilizes a radar sensor
and a forward facing camera designed to detect a vehicle
directly ahead of you.
NOTE:
 If the ACC sensor detects a vehicle ahead, ACC will
apply limited braking or acceleration (not to exceed the
original set speed) automatically to maintain a preset
following distance, while matching the speed of the
vehicle ahead. 
Any chassis/suspension or tire size modifications to
the vehicle will affect the performance of the Adaptive
Cruise Control and Forward Collision Warning system.
 In vehicles NOT equipped with the Active Driving Assist
system, Fixed Speed Cruise Control (ACC not enabled)
will not detect vehicles directly ahead of you. Always be
aware of the feature selected
Úpage 382.
WARNING!
Cruise Control can be dangerous where the system
cannot maintain a constant speed. Your vehicle could
go too fast for the conditions, and you could lose control
and have an accident. Do not use Cruise Control in
heavy traffic or on roads that are winding, icy,
snow-covered or slippery.
WARNING!
 Adaptive Cruise Control (ACC) is a convenience
system. It is not a substitute for active driver involve -
ment. It is always the driver’s responsibility to be
attentive of road, traffic, and weather conditions,
vehicle speed, distance to the vehicle ahead and,
most importantly, brake operation to ensure safe
operation of the vehicle under all road conditions.
Your complete attention is always required while
driving to maintain safe control of your vehicle.
Failure to follow these warnings can result in a colli -
sion and death or serious personal injury.
 The ACC system:
 Does not react to pedestrians, oncoming vehi -
cles, and stationary objects (e.g., a stopped
vehicle in a traffic jam or a disabled vehicle).
 Cannot take street, traffic, and weather condi -
tions into account, and may be limited upon
adverse sight distance conditions.

23_WS_OM_EN_USC_t.book Page 139

STARTING AND OPERATING143
Setting The Following Distance In ACC
The specified following distance for ACC can be set by
varying the distance setting between four bars (longest),
three bars (long), two bars (medium) and one bar (short).
Using this distance setting and the vehicle speed, ACC
calculates and sets the distance to the vehicle ahead. This
distance setting appears in the instrument cluster display.

Distance Settings

To increase the distance setting, push the Distance
Increase button and release. Each time the button is
pushed, the distance setting increases by one bar (longer). To decrease the distance setting, push the Distance
Decrease button and release. Each time the button is
pushed, the distance setting decreases by one bar
(shorter).
If there is no vehicle ahead, the vehicle will maintain the
set speed. If a slower moving vehicle is detected in the
same lane, the instrument cluster display will show the
ACC Set With Target Detected Indicator Light, and the
system will adjust the vehicle speed automatically to
maintain the distance setting, regardless of the set speed.
The vehicle will then maintain the set distance until:

The vehicle ahead accelerates to a speed above the
set speed.
 The vehicle ahead moves out of your lane or view of the
sensor.
 The distance setting is changed.
 The system disengages
Úpage 141.
The maximum braking applied by ACC is limited; however,
the driver can always apply the brakes manually, if
necessary.
NOTE:The brake lights will illuminate whenever the ACC system
applies the brakes. A Proximity Warning will alert the driver if ACC predicts that
its maximum braking level is not sufficient to maintain the
set distance. If this occurs, a visual alert “BRAKE!” will
flash in the instrument cluster display and a chime will
sound while ACC continues to apply its maximum braking
capacity.
NOTE:The “BRAKE!” screen in the instrument cluster display is a
warning for the driver to take action and does not neces
-
sarily mean that the Forward Collision Warning system is
applying the brakes autonomously.
Overtake Aid
When driving with Adaptive Cruise Control (ACC) engaged
and following a vehicle, the system will provide an
additional acceleration up to the ACC set speed to assist
in passing the vehicle. This additional acceleration is
triggered when the driver utilizes the left turn signal and
will only be active when passing on the left side.
ACC Operation At Stop
If the ACC system brings your vehicle to a standstill while
following a vehicle ahead, your vehicle will resume motion,
without any driver interaction, if the vehicle ahead starts
moving within two seconds of your vehicle coming to a
standstill.
If the vehicle in front does not start moving within two
seconds of your vehicle coming to a standstill, the driver
will either have to push the RES (resume) button, or apply
the accelerator pedal to reengage the ACC to the existing
set speed.
1 — Longest Distance Setting (Four Bars)
2 — Medium Distance Setting (Two Bars)
3 — Long Distance Setting (Three Bars)
4 — Short Distance Setting (One Bar)

144STARTING AND OPERATING
NOTE:
If your vehicle is at a standstill for longer than two
seconds, the system will hold brake pressure for up to
10 minutes. If no driver action is taken after the
10 minutes, the Electric Park Brake will be applied and
the ACC system will cancel.
 While ACC is holding your vehicle at a standstill (or the
vehicle is traveling below 3 mph (5 km/h), and the
driver seat belt is unbuckled or the driver door is
opened, the Electric Park Brake will be applied and the
ACC system will cancel.
Display Warnings And Maintenance
“WIPE FRONT RADAR SENSOR IN FRONT OF
VEHICLE” WARNING
The “ACC Unavailable Wipe Front Radar Sensor” warning
will display and a chime will sound when conditions
temporarily limit system performance.
This most often occurs at times of poor visibility, such as
in snow or heavy rain. The ACC system may also become
temporarily blinded due to obstructions, such as mud, dirt
or ice. In these cases, the instrument cluster display will
display this message and the system will deactivate. This message can sometimes be displayed while driving in
highly reflective areas (i.e. ice and snow, or tunnels with
reflective tiles). The ACC system will recover after the
vehicle has left these areas. Under rare conditions, when
the radar is not tracking any vehicles or objects in its path
this warning may temporarily occur.
NOTE:If the “ACC Unavailable Wipe Front Radar Sensor” warning
is active, Fixed Speed Cruise Control is still available.
If weather conditions are not a factor, the driver should
examine the sensor. It may require cleaning or removal of
an obstruction. The sensor is located in the center of the
vehicle behind the lower grille.
To keep the ACC System operating properly, it is important
to note the following maintenance items:

Always keep the sensor clean. Carefully wipe the
sensor lens with a soft cloth. Be cautious not to
damage the sensor lens.
 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
malfunction. 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 Unavailable Wipe Front Radar Sensor”
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 an
authorized dealer.
 Installing a snowplow, front-end protector, an after -
market grille or modifying the grille is not recom -
mended. Doing so may block the sensor and inhibit
ACC operation.
“CLEAN FRONT WINDSHIELD” WARNING
The “ACC Limited Functionality Clean Front Windshield”
warning will display, and a chime will sound when
conditions temporarily limit system performance. This
most often occurs at times of poor visibility, such as in
snow or heavy rain and fog. The ACC system may also
become temporarily blinded due to obstructions, such as
mud, dirt, or ice on windshield and fog on the inside of
glass. In these cases, the instrument cluster display will
read “ACC Limited Functionality Clean Front Windshield”
and the system will have degraded performance.
This message can sometimes be displayed while driving in
adverse weather conditions. The ACC system will recover
after the vehicle has left these areas. Under rare
conditions, when the camera is not tracking any vehicles
or objects in its path this warning may temporarily occur.
WARNING!
When the ACC system is resumed, the driver must
ensure that there are no pedestrians, vehicles or
objects in the path of the vehicle. Failure to follow these
warnings can result in a collision and death or serious
personal injury.

23_WS_OM_EN_USC_t.book Page 144

148STARTING AND OPERATING
Speed Limit Exceeded
When the vehicle’s speed exceeds the displayed speed
limit by 3 mph (5 km/h), the speed limit sign on the
instrument cluster display will show a red outline to alert
the driver.ACTIVE DRIVING ASSIST SYSTEM —
IF EQUIPPED
OPERATION
The Active Driving Assist (ADA) system is combined with
the Adaptive Cruise Control (ACC) system, and centers the
vehicle in the driving lane while traveling at speeds up to
90 mph (145 km/h).
For ACC system operating instructions and system
limitations, see
Úpage 139.
NOTE:
The driver should always obey traffic laws and speed
limits. Never drive above applicable speed limit restric -
tions.
 The driver can override ADA at any time by braking,
accelerating, or steering the vehicle.
Just like ACC, ADA will maintain a set speed as long as the
set distance between your vehicle and the vehicle in front
is maintained. ADA will also keep your vehicle centered
between the lane lines, and monitor for other vehicles in
adjacent lanes by utilizing the Blind Spot Monitoring
sensors.
Two types of Active Driving Assist systems are available:
 Base ADA system
 Hands-Free ADA system
Base Active Driving Assist System — If Equipped
The Base ADA system uses sensors within the steering
wheel to measure driver attentiveness, and requires that
the driver have their hands on the steering wheel at all
times. The system will generally aim to keep the vehicle centered
in the lane, but when the driver turns the steering wheel
(e.g. to move farther away from a large vehicle in an
adjacent lane) the system will reduce its control and enter
"co-steering" mode. While in co-steering mode, the system
will provide reduced assistance and allow the driver to
control the path of the vehicle. Once the driver stops
providing input to the steering wheel, the system will
require a few seconds to fully resume lane centering
assistance, especially during curves.
Hands-Free Active Driving Assist System — If Equipped
The Hands-Free ADA system uses sensors within the
steering wheel and a driver monitoring camera located on
top of the steering column to monitor driver attentiveness.
The Hands-Free ADA system allows the driver to remove
their hands from the steering wheel when engaged, but
requires that the driver continue to pay attention to the
road.
The Hands-Free ADA system will also change lanes when
a turn signal is activated if the adjacent lane in the
direction indicated is clear of another vehicle, and lane
markings are detected (noted by a dashed line in the
direction of the available lane change). The system uses
sensors, including Blind Spot Monitoring (BSM) sensors,
to determine if a lane change is possible. If the assisted
lane change is in progress, a green arrow will appear. If a
lane change is requested but the direction indicated is not
possible, a yellow arrow will appear. Once conditions are
clear, the arrow will turn green and the assisted lane
change will begin.
CAUTION!

Functionality may be limited or the system may not
work if the sensor is obstructed.
 The system may have limited operation or not work at
all in weather conditions such as heavy rain, hail, and
thick fog. Strong light contrasts can influence the
recognition capability of the sensor.
 The area surrounding the sensor must not be
covered with stickers or any other object.
 Do not tamper or perform any operations in the area
of the windshield glass directly surrounding the
sensor.
 Clean foreign matters such as bird droppings,
insects, snow or ice on the windshield. Use specific
detergents and clean cloths to avoid scratching the
windshield.

23_WS_OM_EN_USC_t.book Page 148

STARTING AND OPERATING149
(Continued)
Additionally, Hands-Free ADA will slow the vehicle down
when approaching and going through sharp curves.

Assisted Lane Change (Green Left Arrow)

Extended Auto Resume
If equipped with Hands-Free ADA and the system brings
your vehicle to a stop while following the vehicle ahead,
your vehicle will automatically resume driving without
driver input when the path in front of the vehicle is clear
and the driver is attentive. The path in front of the vehicle
is determined to be clear based on the forward facing
camera, front radars, and front ultrasonic sensors. If the vehicle in front does not start moving after
10 minutes, the Electric Park Brake (EPB) will be applied
and the system will cancel.
NOTE:

The Hands-Free Active Driving Assist system is only
available on approved compatible roadways and
requires an active subscription through the Uconnect
Connected Services package. If the ADA on/off button
is pushed without an active subscription, the instru -
ment cluster display will show the message “Active
Driving Assist Unavailable Update Subscription”. Refer
to the Uconnect Owner’s Manual Supplement for
further information.
 If previously disabled, activating the Hands-Free Active
Driving Assist system will also activate the Forward
Collision Warning and Pedestrian Emergency Braking
systems
Úpage 250.
 If the vehicle is equipped with the Uconnect Connected
Services package, additional data may be collected
through the Connected Services system. This includes
information about the vehicle’s operation, a collision
involving the vehicle, the use of the vehicle and its
features, and in certain situations, the location and
approximate GPS speed of the vehicle. Refer to the
Uconnect Owner’s Manual Supplement for Terms and
Conditions and Privacy Statements. 
The driver monitoring camera may record images of the
driver during certain crash, or near crash-like situa -
tions. To retrieve the images recorded by the camera,
special equipment is required and access to the
vehicle or the camera is needed.
 Vehicle data may be read from the Hands-Free ADA
system with special equipment and access to the
vehicle or the Event Data Recorder (EDR).WARNING!
The driver is always responsible for determining if a
lane change is safe. Failure to follow this warning can
result in a collision and death or serious personal
injury.
WARNING!
The Active Driving Assist (ADA) system is a convenience
system. It is not a substitute for active driver
involvement. It is always the driver’s responsibility to be
attentive of road traffic, weather conditions, vehicle
speed, distance to the vehicle ahead, position in the
lane compared to other vehicles, and brake operation
to ensure safe operation of the vehicle under all road
conditions. Your complete attention is always required
while driving to maintain safe control of your vehicle.
Failure to follow these warnings can result in a collision
and death or serious personal injury.
Some states and local laws may require hands to be
kept on the steering wheel at all times. For vehicles
equipped with the Hands-Free ADA system, ONLY
remove your hands from the steering wheel if the
Hands-Free system is engaged, it is safe to do so, and it
is permitted by state and local laws.4
