2015 JEEP WRANGLER tire pressure

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 (if
equipped), or brake fluid leaks are suspected, the cause
should be located and corrected immediately.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 103

Vehicle Odometer Messages
When the appropriate conditions exist, the following
odometer messages will display:
ECO.....................Fuel Saver Indicator
door.............................Door Ajar
gATE........................Swing Gate Ajar
LoW tirE....................LowTirePressure
HOTOIL...........Transmission Oil Temperature
Above Normal Limits
gASCAP......................Fuel Cap Fault
noFUSE..........................Fuse Fault
CHAngE OIL..............OilChange Required
NOTE:If the vehicle is equipped with the optional
Electronic Vehicle Information Center (EVIC) in the in-
strument cluster, all the messages will only be displayed
in the EVIC display. For additional information, refer to
“Electronic Vehicle Information Center — If Equipped”.
ECO (Fuel Saver Indicator) — If Equipped
The ECO indicator will illuminate when you are driving
in a fuel efficient manner and can be used to modify
driving habits in order to increase fuel economy.
LoW tirE
When the appropriate condition exists, the odometer dis-
play will toggle between LoW and tirE for three cycles.
“HOTOIL” Transmission Temperature Warning Message
The “HOTOIL” cluster message will appear in the odom-
eter accompanied with a chime to indicate that there is
excessive transmission fluid temperature that might oc-
cur with severe usage such as trailer towing. It may also

26. Hill Decent Indicator
This indicator shows when the Hill Descent
Control (HDC) feature is turned on. The lamp
will be on solid when HDC is armed. HDC can
only be armed when the transfer case is in the
“4WD LOW” position and the vehicle speed is less then
30 mph (48 km/h). If these conditions are not met while
attempting to use the HDC feature, the HDC indicator
light will flash on/off.
27. Cruise Indicator
This indicator shows when the electronic speed
control system is turned on.
28. 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.
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
318 UNDERSTANDING YOUR INSTRUMENT PANEL

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 continuously
illuminated. 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.
