flat tire JEEP GRAND CHEROKEE 2016 WK2 / 4.G Owners Manual

Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks, and bulges.
Check the wheel nuts for tightness. Check the tires
(including spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, power steering fluid (if
equipped), or brake fluid leaks are suspected. The cause
should be located and corrected immediately.
114 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!
ALWAYS obey traffic laws and pay attention to the
road. Some Uconnect Access services, including 9-1-1
and Assist, will NOT work without an operable 1X
(voice/data) or 3G (data) network connection.
NOTE:
• Your vehicle may be transmitting data as authorized
by the subscriber.
• The 9–1–1 and ASSIST buttons will only function if
you are connected to an operable 1X(voice/data) or
3G(data) network. Other Uconnect services will only
be operable if your Uconnect Access service is active
and you are connected to an operable 1X(voice/data)
or 3G(data) network. ASSIST Call
The ASSIST Button is used to automatically connect you
to any one of the following support centers:
•
Roadside Assistance – If you get a flat tire, or need a
tow, just push the ASSIST button and you’ll be con-
nected to someone who can help. Roadside Assistance
will know what vehicle you’re driving and its location.
Additional fees may apply for roadside Assistance.
• Uconnect Access Customer Care – In-vehicle support
for Uconnect Access and Uconnect Access Via Mobile
features.
• Vehicle Customer Care – Total support for all other
vehicle issues.

IMPORTANT:Do not continue driving with one or more
flat tires as handling may be compromised. Stop the
vehicle, avoiding sharp braking and steering. Repair
immediately using the dedicated tire repair kit and
contact your authorized dealership as soon as possible.
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 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 illumi-
nates, 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 will flash for

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.
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
hydroplaning. ESC also cannot prevent accidents
resulting from loss of vehicle control due to inap-
propriate driver input for the conditions. Only a
safe, attentive, and skillful driver can prevent acci-
dents. The capabilities 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 main-
tain your vehicle, may change the handling charac-
teristics 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 un-
evenly worn tires may also degrade ESC perfor-
mance. 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.
516 STARTING AND OPERATING

EXAMPLE:
Service Description: 95= Load Index
– A numerical code associated with the maximum load a tire can carry
H = Speed Symbol
– A symbol indicating the range of speeds at which a tire can carry a load corresponding to
its load index under certain operating conditions
– The maximum speed corresponding to the speed symbol should only be achieved under
specified operating conditions (i.e., tire pressure, vehicle loading, road conditions, and
posted speed limits)
Load Identification:
Absence of the following load identification symbols on the sidewall of the tire indicates a Standard Load (SL) tire:
•XL = Extra load (or reinforced) tire, or
•LL= Light load tire or
•C, D, E, F, G = Load range associated with the maximum load a tire can carry at a specified pressure
Maximum Load– Maximum load indicates the maximum load this tire is designed to carry
Maximum Pressure–Maximum pressure indicates the maximum permissible cold tire inflation pressure for this tire
532 STARTING AND OPERATING

EXAMPLE:
DOT MA L9 ABCD 0301
01 = Number representing the year in which the tire was manufactured (two digits)
– 01 means the year 2001
– Prior to July 2000, tire manufacturers were only required to have one number to represent the year
in which the tire was manufactured. Example: 031 could represent the 3rd week of 1981 or 1991
Tire Terminology And Definitions
Term Definition
B-Pillar The vehicle B-Pillar is the structural member of the body located
behind the front door.
Cold Tire Inflation Pressure Cold tire inflation pressure 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 sitting for a minimum of three
hours. Inflation pressure is measured in units of PSI (pounds per
square inch) or kPa (kilopascals).
534 STARTING AND OPERATING

TermDefinition
Maximum Inflation Pressure The maximum inflation pressure is the maximum permissible
cold tire inflation pressure for this tire. The maximum inflation
pressure is molded into the sidewall.
Recommended Cold Tire Inflation Pressure Vehicle manufacturer’s recommended cold tire inflation pressure
as shown on the tire placard.
Tire Placard
A label permanently attached to the vehicle describing the vehicle’s
loading capacity, the original equipment tire sizes and the recom-
mended cold tire inflation pressures.5
