326IN CASE OF EMERGENCY
NOTE:The Safehold feature will engage the Electric Park
Brake whenever the driver's door is opened (if the
ignition is ON, transmission is not in PARK, and
brake pedal is released). If you are towing this
vehicle with the ignition in the ON/RUN mode, you
must manually disable the Electric Park Brake
each time the driver's door is opened, by pressing
the brake pedal and then releasing the EPB.
If the key fob is unavailable or the vehicle's battery
is discharged, detailed instructions on shifting the
transmission out of PARK in order to move the
vehicle Úpage 321.
ALL WHEEL DRIVE (AWD) MODELS
FCA US LLC recommends towing your vehicle with
all four wheels OFF the ground using a flatbed.
ENHANCED ACCIDENT RESPONSE SYSTEM
(EARS)
This vehicle is equipped with an Enhanced
Accident Response System.
This feature is a communication network that
takes effect in the event of an impact. Detailed
information can be found on Ú page 272.
EVENT DATA RECORDER (EDR)
This vehicle is equipped with an event data
recorder (EDR). The main purpose of an EDR is to
record data that will assist in understanding how a
vehicle’s systems performed under certain crash
or near crash-like situations, such as an air bag
deployment or hitting a road obstacle. Detailed
information can be found on Úpage 274.
CAUTION!
Do not use sling-type equipment when towing.
Vehicle damage may occur.
When securing the vehicle to a flatbed truck,
do not attach to front or rear suspension
components. Damage to your vehicle may
result from improper towing.
Ensure that the Electric Park Brake is
released, and remains released, while being
towed.
CAUTION!
Towing this vehicle using any other method
can cause severe transmission and/or
transfer case damage.

366SERVICING AND MAINTENANCE
Life Of Tire
The service life of a tire is dependent upon varying
factors including, but not limited to:
Driving style.
Tire pressure - Improper cold tire inflation pres -
sures can cause uneven wear patterns to
develop across the tire tread. These abnormal
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 scheduled maintenance is highly
recommended.
NOTE:Wheel valve stem must be replaced as well when
installing new tires due to wear and tear in existing
tires. 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 Tires
The tires on your new vehicle provide a balance of
many characteristics. They should be inspected
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 Ú
page 365. 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 Ú page 357.
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 you ever
replace a wheel, make sure that the wheel’s
specifications match those of the original wheels.
It is recommended you contact an authorized tire
dealer or original equipment dealer with any
questions you may have on tire specifications or
capability. Failure to use equivalent replacement
tires may adversely affect the safety, handling, and
ride of your vehicle.
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 serious injury or
death.
WARNING!
Do not use a tire, wheel size, load rating, or
speed rating other than that specified for your
vehicle. Some combinations of unapproved
tires and wheels may change suspension
dimensions and performance characteristics,
resulting in changes to steering, handling, and
braking of your vehicle. This can cause unpre -
dictable handling and stress to steering and
suspension components. You could lose
control and have a collision resulting in
serious injury or death. Use only the tire and
wheel sizes with load ratings approved for
your vehicle.
Never use a tire with a smaller load index or
capacity, other than what was originally
equipped on your vehicle. Using a tire with a
smaller load index could result in tire over -
loading and failure. You could lose control and
have a collision.
Failure to equip your vehicle with tires having
adequate speed capability can result in
sudden tire failure and loss of vehicle control.
