Safe Usage Of The Uconnect System
The Uconnect system is a sophisticated electronic
device. Do not let young children use the system.
 Permanent hearing loss may occur if you play your
music or sound system at loud volumes. Exercise
caution when setting the volume on the system.
 Keep drinks, rain and other sources of moisture away
from the system. Besides damage to the system,
moisture can cause electric shocks as with any
electronic device.
NOTE:Many features of this system are speed dependent.
For your own safety, it is not possible to use some of the
touchscreen features while the vehicle is in motion.
Care And Maintenance
Do not press the touchscreen with any hard or sharp
objects (pen, USB stick, jewelry, etc.), which could
scratch the surface.
 Do not spray any liquid or chemicals directly on the
screen! Use a clean and dry microfiber lens cleaning
cloth in order to clean the touchscreen.
 If necessary, use a lint-free cloth dampened with a
cleaning solution, such as isopropyl alcohol or an
isopropyl alcohol and water solution ratio of 50:50. Be
sure to follow the solvent manufacturer's precautions
and directions

UCONNECT MODES
STEERING WHEEL AUDIO CONTROLS
The remote sound system controls are located on the rear
surface of the steering wheel at the three and nine o’clock
positions.

Remote Sound System Controls

The right-hand control is a rocker-type switch with a push
button in the center and controls the volume and mode of
the sound system. Pushing the top of the rocker switch will
increase the volume, and pushing the bottom of the rocker
switch will decrease the volume. Pushing the right-hand control’s center button will make
the radio switch between the various modes available
(AM/FM/SXM or Media, etc.).
The left-hand control is a rocker-type switch with a push
button in the center. The function of the left-hand control
is different depending on which mode you are in.
The following describes the left-hand control operation in
each mode:
Radio Operation
Pushing the top of the switch will seek up for the next
available station and pushing the bottom of the switch will
seek down for the next available station.
The button located in the center of the left-hand control
will tune to the next preset station that you have
programmed in the radio presets.
Media Mode
Pushing the top of the switch skips to the next track on the
selected media (AUX/USB/Bluetooth®). Pushing the
switch up twice will go forward two tracks. Pushing the
bottom switch goes to the beginning of the current track,
or the beginning of the previous track if it is within eight
seconds after the current track begins to play. Double
pressing the bottom button switch will skip to the previous
track if it is after eight seconds into the current track.

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 the
previously mentioned 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.
ESC Operating Modes
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
This mode may be useful if the vehicle becomes stuck.
This mode may modify TCS and ESC thresholds for
activation, which allows for more wheel spin than normally
allowed.
To enter the “Partial Off” mode, momentarily push the ESC
OFF button and the ESC OFF Indicator Light will illuminate.
To turn the ESC on again, momentarily push the ESC OFF
button and the ESC OFF Indicator Light will turn off.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.
WARNING!
When in “Partial Off” mode, the TCS functionality 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.

(Continued)
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 253 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.
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 tire pressure warning
(TPMS Warning Light) illuminates, you must 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
Úpage 284.
NOTE:
 The TPMS is not intended to replace normal tire care
and maintenance or to provide warning of a tire failure
or condition.
 The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure, unless your vehicle
is equipped with a Tire Fill Alert (TFA) system.
 Driving on a significantly underinflated tire causes the
tire to overheat and can lead to tire failure. Underinfla -
tion also reduces fuel efficiency and tire tread life, and
may affect the vehicle’s handling and stopping ability.
 The TPMS is not a substitute for proper tire mainte -
nance, and it is the driver’s responsibility to maintain
correct tire pressure using an accurate tire pressure
gauge, even if underinflation has not reached the level
to trigger illumination of the TPMS Warning Light.
 Seasonal temperature changes will affect tire pres -
sure, and the TPMS will monitor the actual tire pres -
sure in the tire.
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.
The TPMS sensor is not designed for use on after -
market wheels and may contribute to a poor overall
system performance or sensor damage. Customers
are encouraged to use Original Equipment Manufac -
turer (OEM) wheels to ensure proper TPMS feature
operation.
 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.
 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.
CAUTION!

NOTE:Vehicles with the front passenger seat deleted will not be
equipped with the Seat Belt Buckle Switch, Seat Belt
Pretensioner, Supplemental Seat Mounted Side Airbag,
and Seat Track Position Sensors for the front passenger.
All passenger occupants within the vehicle must be in a
seat equipped with a Seat Belt System and Head Restraint
for the safety of the passenger.
If the front passenger and/or rear seats have been
removed do not ride in those areas.
Air Bag Warning Light
The Occupant Restraint Controller (ORC)
monitors the readiness of the electronic parts
of the air bag system whenever the ignition
switch is in the START or ON/RUN position. If
the ignition switch is in the OFF position or in the ACC
position, the air bag system is not on and the air bags will
not inflate.
The ORC contains a backup power supply system that may
deploy the air bag system even if the battery loses power
or it becomes disconnected prior to deployment. The ORC turns on the Air Bag Warning Light in the
instrument panel for approximately four to eight seconds
for a self-check when the ignition switch is first in the ON/
RUN position. After the self-check, the Air Bag Warning
Light will turn off. If the ORC detects a malfunction in any
part of the system, it turns on the Air Bag Warning Light,
either momentarily or continuously. A single chime will
sound to alert you if the light comes on again after initial
startup.
The ORC also includes diagnostics that will illuminate the
instrument panel Air Bag Warning Light if a malfunction is
detected that could affect the air bag system. The
diagnostics also record the nature of the malfunction.
While the air bag system is designed to be maintenance
free, if any of the following occurs, have an authorized
dealer service the air bag system immediately.

The Air Bag Warning Light does not come on during the
four to eight seconds when the ignition switch is first in
the ON/RUN position.
 The Air Bag Warning Light remains on after the four to
eight-second interval.
 The Air Bag Warning Light comes on intermittently or
remains on while driving.
NOTE:If the speedometer, tachometer, or any engine related
gauges are not working, the Occupant Restraint Controller
(ORC) may also be disabled. In this condition the air bags
may not be ready to inflate for your protection. Have an
authorized dealer service the air bag system immediately.
Redundant Air Bag Warning Light
If a fault with the Air Bag Warning Light is
detected, which could affect the Supplemental
Restraint System (SRS), the Redundant Air Bag
Warning Light will illuminate on the instrument
panel. The Redundant Air Bag Warning Light will stay on
until the fault is cleared. In addition, a single chime will
sound to alert you that the Redundant Air Bag Warning
Light has come on and a fault has been detected. If the
Redundant Air Bag Warning Light comes on intermittently
or remains on while driving have an authorized dealer
service the vehicle immediately
Úpage 63.
WARNING!
Ignoring the Air Bag Warning Light in your instrument
panel could mean you won’t have the air bag system to
protect you in a collision. If the light does not come on
as a bulb check when the ignition is first turned on,
stays on after you start the vehicle, or if it comes on as
you drive, have an authorized dealer service the air bag
system immediately.
