GENERAL INFORMATION ON
RADIO FREQUENCIES
This device complies with Part 15 of the
FCC Rules and with Industry Canada
license-exempt RSS standard(s).
Operation is subject to the following two
conditions: (1) This device may not cause
harmful interference, and (2) This device
must accept any interference received,
including interference that may cause
undesired operation.
WARNING: Changes or
modifications not expressively approved
by the party responsible for compliance
could void the user's authority to operate
the equipment. The term "IC:" before the
radio certification number only signifies
that Industry Canada technical
specifications were met.
The typical operating range for your
transmitter is approximately
33 ft (10 m).
Vehicles with the remote start feature will
have a greater range.
One of the following could cause a
decrease in operating range:
• Weather conditions.
• Nearby radio towers.
• Structures around the vehicle.
• Other vehicles parked next to your
vehicle.
The radio frequency used by your remote
control can also be used by other radio
transmitters, for example amateur radios,
medical equipment, wireless headphones,
wireless remote controls, cell phones,
battery chargers and alarm systems. If the
frequencies are jammed, you will not be
able to use your remote control. You can
lock and unlock the doors with the key.
Note: Make sure to lock your vehicle before
leaving it unattended. Note:
If you are in range, the remote control
will operate if you press any button
unintentionally.
Note: The remote control contains sensitive
electrical components. Exposure to moisture
or impact may cause permanent damage.
Intelligent Access
(If Equipped)
The system uses a radio frequency signal
to communicate with your vehicle and
authorize your vehicle to unlock when one
of the following conditions are met:
• You activate the front exterior door
handle switch.
• You press the luggage compartment
button.
• You press a button on the transmitter.
If excessive radio frequency interference
is present in the area or if the transmitter
battery is low, you may need to
mechanically unlock your door. You can
use the mechanical key blade in your
intelligent access key to open the driver
door in this situation. See
Remote
Control (page 55).
REMOTE CONTROL
(IF EQUIPPED)
Integrated Keyhead Transmitter
Use the key blade to start your vehicle and
unlock or lock the driver door from outside
your vehicle. The integrated keyhead
transmitter functions as a programmed
ignition key that operates all the locks and
starts your vehicle, as well as a remote
control.

that Industry Canada technical
specifications were met.
This equipment complies with FCC
radiation exposure limits set forth for an
uncontrolled environment. End Users must
follow the specific operating instructions
for satisfying RF exposure compliance. This
transmitter must be at least
8 in (20 cm)
from the user and must not be co-located
or operating in conjunction with any other
antenna or transmitter.
The term “IC:” before the

Operation is subject to:
• This device may not cause interference.
• This device must accept any
interference, including interference that
may cause undesired operation of the
device.
Note: The charging performance may be
affected if your device is in a case. It may be
necessary to remove the case to wirelessly
charge your device.
The system supports one Qi wireless
charging compatible device on the
charging area.
Keep the charging area clean and remove
foreign objects prior to charging a device.
Do not place items with a magnetic strip,
for example passports, parking tickets or
credit cards, near the charging area when
charging a device. Damage may occur to
the magnetic strip. Do not place metal objects, for example
remote controls, coins and candy
wrappers, on or near the charging area
when charging a device. Metal objects may
heat up and degrade the charging
performance.
Note:
The rate of charge, or charging power,
is controlled by the device. During charging,
the device and the charger may heat up, this
is normal. If the battery gets hotter than
usual, the charger may stop charging. The charging area is on the
center console or lower
instrument panel.
See Center
Console (page 171).
You can charge a device if the vehicle is
on, when in accessory mode, or anytime
SYNC is on.
To begin charging, place the device on the
center of the charging surface with the
charging side down. The charging stops
after your device reaches a full charge.
Note: If the system detects a foreign object
or if the device is misaligned on the charging
area, a message appears in the display.
Note: Software and firmware updates may
affect device compatibility, including the
use of unofficial software or firmware. You
should verify charging functionality with your
specific devices when in your vehicle. Description

As an added safety feature, your vehicle
has been equipped with a Tire Pressure
Monitoring System (TPMS) that
illuminates a low tire pressure 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 pressure. Driving on a
significantly under-inflated tire causes the
tire to overheat and can lead to tire failure.
Under-inflation 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 under-inflation
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 flashes for
approximately one minute and then
remains continuously illuminated. This
sequence continues 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.
This device complies with Part 15 of the
FCC Rules and with Industry Canada
license-exempt RSS standard(s).
Operation is subject to the following two
conditions:
•
This device may not cause harmful
interference.
• This device must accept any
interference received, including
interference that may cause undesired
operation.
Note: Changes or modifications not
expressively approved by the party
responsible for compliance could void the
user's authority to operate the equipment.
The term "IC" before the radio certification
number only signifies that Industry Canada
technical specifications were met.

TECHNICAL SPECIFICATIONS
Wheel Lug Nut Torque Specifications
WARNING: When you install a wheel, always remove any corrosion, dirt or foreign
materials present on the mounting surfaces of the wheel or the surface of the wheel
hub, brake drum or brake disc that contacts the wheel. Make sure to secure any fasteners
that attach the rotor to the hub so they do not interfere with the mounting surfaces of
the wheel. Installing wheels without correct metal-to-metal contact at the wheel
mounting surfaces can cause the wheel nuts to loosen and the wheel to come off while
your vehicle is in motion, resulting in loss of vehicle control, personal injury or death. lb.ft (Nm)

On vehicles equipped with single rear wheels, retighten the lug nuts to the specified torque
at 100 mi (160 km) after any wheel disturbance, such as tire rotation, changing a flat tire,
or wheel removal.
On vehicles equipped with dual rear wheels, retighten the wheel lug nuts to the specified
torque at
100 mi (160 km), and again at 500 mi (800 km) of new vehicle operation and
after any wheel disturbance, such as tire rotation, changing a flat tire, or wheel removal.
It is important to follow the proper wheel mounting and lug nut torque procedures. Wheel pilot bore
