2013 JEEP GRAND CHEROKEE tires

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 positive 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, or
brake fluid leaks are suspected, the cause should be
located and corrected immediately.
116 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

10. Electronic Vehicle Information Center (EVIC)
Display/Odometer Display
The odometer display shows the total distance the ve-
hicle has been driven.
U.S. Federal regulations require that upon transfer of
vehicle ownership, the seller certify to the purchaser the
correct mileage that the vehicle has been driven. If your
odometer needs to be repaired or serviced, the repair
technician should leave the odometer reading the same
as it was before the repair or service. If s/he cannot do so,
then the odometer must be set at zero, and a sticker must
be placed in the door jamb stating what the mileage was
before the repair or service. It is a good idea for you to
make a record of the odometer reading before the repair/
service, so that you can be sure that it is properly reset, or
that the door jamb sticker is accurate if the odometer
must be reset at zero.When the appropriate conditions exist, this display
shows the Electronic Vehicle Information Center (EVIC)
messages. Refer to “Electronic Vehicle Information
Center”.
11. Tire Pressure Monitoring Telltale Light
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.
318 UNDERSTANDING YOUR INSTRUMENT PANEL

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
approximately one minute and then remain continuouslyilluminated. This sequence will continue upon subse-
quent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the sys-
tem 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.

CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system opera-
tion or sensor damage may result when using re-
placement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Do not use tire sealant from a can or
balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result.12. Park/Headlight ON Indicator — If Equipped
This indicator will illuminate when the park
lights or headlights are turned on.
13. Seat Belt Reminder Light When the ignition switch is first turned to the
ON/RUN position, this light will turn on for four
to eight seconds as a bulb check. During the bulb
check, if the driver’s seat belt is unbuckled, a chime will
sound. After the bulb check or when driving, if the driver
or front passenger seat belt remains unbuckled, the Seat
Belt Indicator Light will flash or remain on continuously.
Refer to “Occupant Restraints” in “Things To Know
Before Starting Your Vehicle” for further information.

•System Warnings Displayed (will display all currently
active System Warnings)
• Tire Pressure Monitor System (shows the current pres-
sure of all four road tires). For additional information,
refer to “Tire Pressure Monitor System” in “Starting
And Operating”. NOTE:
•
Tires heat up during normal driving conditions. Heat
will cause the tire pressure to increase from 2 to 6 psi
(14 to 41 kPa) during normal driving conditions. Refer
to “Tires-General Information/Tire Inflation Pres-
sures” in “Starting And Operating” for additional
information.
• Your system can be set to display pressure units in PSI,
kPa, or BAR.
Keyless Enter-N-Go™ Display — If Equipped
When the ENGINE START/STOP button is pressed to
change ignition switch positions, the Keyless Enter-N-
Go™ icon momentarily appears in the lower right corner
of the EVIC display showing the new ignition switch
position.

the intended path, ESC applies the brake of the appro-
priate wheel to assist in counteracting the oversteer or
understeer condition.
•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.
The “ESC Activation/Malfunction Indicator Light” lo-
cated in the instrument cluster will start to flash as soon
as the tires lose traction and 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.WARNING!
The Electronic Stability Control (ESC) cannot pre-
vent the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded by
prevailing road conditions. ESC cannot prevent col-
lisions, including those resulting from excessive
speed in turns, driving on very slippery surfaces, or
hydroplaning. ESC also cannot prevent collisions
resulting from loss of vehicle control due to inappro-
priate driver input for the conditions. Only a safe,
attentive, and skillful driver can prevent collisions.
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.
