tomer service line. Some services require im-
mediate response selection. In some instances,
that may be too quick for use of the Uconnect
Phone.
When calling a number with your Uconnect
Phone that normally requires you to enter in a
touch-tone sequence on your mobile phone
keypad, you can push the Voice Command
button and say the sequence you wish to
enter, followed by the word “Send.” For ex-
ample, if required to enter your PIN followed
with a pound, (3746#),youcanpush the
Voice Command
button and say, “3746#
Send.” Saying a number, or sequence of num-
bers, followed by “Send,” is also to be used for
navigating through an automated customer ser-
vice center menu structure, and to leave a
number on a pager.
You can also send stored Uconnect phonebook
entries as tones for fast and easy access to
voice mail and pager entries. To use this fea-
ture, dial the number you wish to call and then
push the Voice Command
button and say
“Send.” The system will prompt you to enter the
name or number and say the name of the
phonebook entry you wish to send. TheUconnect Phone will then send the correspond-
ing phone number associated with the phone-
book entry, as tones over the phone.
NOTE:
•You may not hear all of the tones due to
mobile phone network configurations.
This is normal.
•Some paging and voice mail systems
have system time out settings that are too
short and may not allow the use of this
feature.
Barge In — Overriding Prompts
The “Voice Command” button can be used
when you wish to skip part of a prompt and
issue your voice command immediately. For
example, if a prompt is asking “Would you like to
pair a phone, clear a...,” you could push the
Voice Command
button and say, “Pair a
Phone” to select that option without having to
listen to the rest of the voice prompt.Turning Confirmation Prompts ON/OFF
Turning confirmation prompts off will stop the
system from confirming your choices (e.g., the
Uconnect Phone will not repeat a phone num-
ber before you dial it).
1. Push the Phone
button to begin.
2. After the “Ready” prompt and the following
beep, say one of the following:
•“Setup Confirmation Prompts On”
•“Setup Confirmation Prompts Off”
Phone And Network Status Indicators
If available on the radio and/or on a premium
display such as the instrument panel cluster,
and supported by your mobile phone, the
Uconnect Phone will provide notification to in-
form you of your phone and network status
when you are attempting to make a phone call
using Uconnect Phone. The status is given for
network signal strength, phone battery strength,
etc.

Yellow Telltale Indicator Lights
Engine Check/Malfunction Indicator Light (MIL)
Yellow Telltale Light What It Means
Engine Check/Malfunction Indicator Light (MIL)The Engine Check/Malfunction Indicator Light (MIL) is a part of an Onboard Diagnostic System called OBD II that monitors en-
gine and automatic transmission control systems. The light will illuminate when the ignition is in the ON position before engine
start. If the bulb does not come on when turning the key from OFF to ON/RUN, have the condition checked promptly.
Certain conditions, such as a loose or missing gas cap, poor quality fuel, etc., may illuminate the light after engine start.
The vehicle should be serviced if the light stays on through several typical driving styles. In most situations, the vehicle will
drive normally and will not require towing.
When the engine is running, the MIL may flash to alert serious conditions that could lead to immediate loss of power or
severe catalytic converter damage. The vehicle should be serviced as soon as possible if this occurs.
CAUTION!
Prolonged driving with the Malfunction Indicator
Light (MIL) on could cause damage to the engine
control system. It also could affect fuel economy
and driveability. If the MIL is flashing, severe
catalytic converter damage and power loss will
soon occur. Immediate service is required.
WARNING!
A malfunctioning catalytic converter, as ref-
erenced above, can reach higher tempera-
tures than in normal operating conditions.
This can cause a fire if you drive slowly or

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 Operating” and “Towing A Dis-
abled Vehicle” in “What To Do In Emergen-
cies” for further information.
DRIVE (D)
This range should be used for most city and
highway driving. It provides the smoothest up-
shifts and downshifts, and the best fuel
economy. The transmission automatically up-
shifts through underdrive first, second, third,
and fourth gears, direct fifth gear and overdrive
sixth gear. The DRIVE position provides opti-
mum 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, travel-
ing into strong head winds, or while towing
heavy trailers), use the AutoStick shift control(refer to “AutoStick (Six-Speed Automatic
Transmission)” in this section for further infor-
mation) 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.
If the transmission temperature exceeds normal
operating limits, the transmission controller will
modify the transmission shift schedule and ex-
pand the range of torque converter clutch en-
gagement. This is done to prevent transmission
damage due to overheating. If the transmission
becomes extremely hot, the “Transmission
Temperature Warning Light” may illuminate and
the transmission may operate differently until
the transmission cools down.
During very cold temperatures (-4°F [-20°C] or
below), transmission operation may be modified
depending on engine and transmission tem-
perature as well as vehicle speed. Normal op-
eration will resume once the transmission tem-
perature has risen to a suitable level.
Transmission Limp Home Mode
Transmission function is monitored electroni-
cally for abnormal conditions. If a condition isdetected that could result in transmission dam-
age, Transmission Limp Home Mode is acti-
vated. In this mode, the transmission remains in
fourth gear regardless of which forward gear is
selected. PARK, REVERSE, and NEUTRAL will
continue to operate. The Malfunction Indicator
Light (MIL) may be illuminated. Limp Home
Mode allows the vehicle to be driven to an
authorized dealer for service without damaging
the transmission.
In the event of a momentary problem, the
transmission can be reset to regain all forward
gears by performing the following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK.
3. Turn the ignition switch to the LOCK/OFF
position.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the
problem is no longer detected, the transmis-
sion will return to normal operation.

Run Flat Tires — If EquippedRun Flat tires allow you the capability to drive 50
miles (80 km) at 50 mph (80 km/h) after a rapid
loss of inflation pressure. This rapid loss of
inflation is referred to as the Run Flat mode. A
Run Flat mode occurs when the tire inflation
pressure is of/or below 14 psi (96 kPa). Once a
Run Flat tire reaches the run flat mode it has
limited driving capabilities and needs to be
replaced immediately. A Run Flat tire is not
repairable.
It is not recommended driving a vehicle loaded
at full capacity or to tow a trailer while a tire is in
the run flat mode.
See the tire pressure monitoring section for
more information.
Spare Tires — If Equipped
NOTE:
For vehicles equipped with Tire Service Kit
instead of a spare tire, please refer to “Tire
Service Kit” in “What To Do In Emergencies”
for further information.
CAUTION!
Because of the reduced ground clearance,
do not take your vehicle through an auto-
matic car wash with a compact or limited-use
temporary spare installed. Damage to the
vehicle may result.
Spare Tire Matching Original Equipped Tire
And Wheel — If Equipped
Your vehicle may be equipped with a spare tire
and wheel equivalent in look and function to the
original equipment tire and wheel found on the
front or rear axle of your vehicle. This spare tire
may be used in the tire rotation for your vehicle.
If your vehicle has this option, refer to an
authorized tire dealer for the recommended tire
rotation pattern.
Compact Spare Tire — If Equipped
The compact spare is for temporary emergency
use only. You can identify if your vehicle is
equipped with a compact spare by looking at
the spare tire description on the Tire and Load-
ing Information Placard located on the driver’s
side door opening or on the sidewall of the tire.
Compact spare tire descriptions begin with theletter “T” or “S” preceding the size designation.
Example: T145/80D18 103M.
T, S = Temporary Spare Tire
Since this tire has limited tread life, the original
equipment tire should be repaired (or replaced)
and reinstalled on your vehicle at the first op-
portunity.
Do not install a wheel cover or attempt to mount
a conventional tire on the compact spare wheel,
since the wheel is designed specifically for the
compact spare tire. Do not install more than one
compact spare tire and wheel on the vehicle at
any given time.
WARNING!
Compact spares are for temporary emer-
gency use only. With these spares, do not
drive more than 50 mph (80 km/h). Tempo-
rary use spares have limited tread life. When
the tread is worn to the tread wear indicators,
the temporary use spare tire needs to be
replaced. Be sure to follow the warnings,

These indicators are molded into the bottom of
the tread grooves. They will appear as bands
when the tread depth becomes a 1/16 of an inch
(1.6 mm). When the tread is worn to the tread
wear indicators, the tire should be replaced.
Refer to “Replacement Tires” in this section for
further information.
Life Of TireThe service life of a tire is dependent upon
varying factors including, but not limited to:•Driving style.
•Tire pressure - Improper cold tire inflation
pressures can cause uneven wear patterns
to develop across the tire tread. These ab-
normal wear patterns will reduce tread life,
resulting in the need for earlier tire
replacement.
•Distance driven.
•Performance tires, tires with a speed rating of
V or higher, and Summer tires typically have
a reduced tread life. Rotation of these tires
per the vehicle maintenance schedule is
highly recommended.
WARNING!
Tires and the spare tire should be replaced
after six years, regardless of the remaining
tread. Failure to follow this warning can
result in sudden tire failure. You could lose
control and have a collision resulting in seri-
ous injury or death.Keep dismounted tires in a cool, dry place with
as little exposure to light as possible. Protect
tires from contact with oil, grease, and gasoline.
Replacement TiresThe tires on your new vehicle provide a balance
of many characteristics. They should be in-
spected regularly for wear and correct cold tire
inflation pressures. The manufacturer strongly
recommends that you use tires equivalent to the
originals in size, quality and performance when
replacement is needed. Refer to the paragraph
on “Tread Wear Indicator”. Refer to the Tire and
Loading Information placard or the Vehicle Cer-
tification Label for the size designation of your
tire. The Load Index and Speed Symbol for your
tire will be found on the original equipment tire
sidewall. See the Tire Sizing Chart example
found in the “Tire Safety Information” section of
this manual for more information relating to the
Load Index and Speed Symbol of a tire.
It is recommended to replace the two front tires
or two rear tires as a pair. Replacing just one tire
can seriously affect your vehicle’s handling. If

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 emis-
sions, engine, and automatic transmission con-
trol systems. When these systems are operat-
ing properly, your vehicle will provide excellent
performance and fuel economy, as well as
engine emissions well within current govern-
ment regulations.
If any of these systems require service, the
OBD II system will turn on the “Malfunction
Indicator Light” (MIL). It will also store diagnos-
tic codes and other information to assist your
service technician in making repairs. Although
your vehicle will usually be drivable and not
need towing, see your authorized dealer for
service as soon as possible.
CAUTION!
•Prolonged driving with the MIL on could
cause further damage to the emission con-
trol 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 engine is
running, severe catalytic converter dam-
age and power loss will soon occur. Imme-
diate 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. Autho-
rized service technicians may need to access
this information to assist with the diagnosis and
service of your vehicle and emissions system.
WARNING!
•ONLY an authorized service technician
should connect equipment to the OBD II
connection port in order to 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, in-
cluding safety related systems, could be
impaired or a loss of vehicle control
could occur that may result in an acci-
dent involving serious injury or death.
•Access, or allow others to access, infor-
mation stored in your vehicle systems,
including personal information.
For further information, refer to “Cybersecurity”
in the “Understanding Your Instrument Panel”
section.
