Tire Pressure Monitor System (Tpms) - Jeep Wrangler 2015 Operating Information Manual

Refer to the "Service and Warranty Handbook"
for the proper maintenance intervals. The rea-
sons for any rapid or unusual wear should be
corrected prior to rotation being performed.
The suggested rotation method is the "forward-
cross" shown in the following diagram.
Tire Rotation
CAUTION!
Proper operation of four-wheel drive vehicles
depends on tires of equal size, type and
circumference on each wheel. Any difference
CAUTION! (Continued)
in tire size can cause damage to the transfer
case. Tire rotation schedule should be fol-
lowed to balance tire wear.
TIRE PRESSURE MONITOR
SYSTEM (TPMS)
The Tire Pressure Monitoring System (TPMS)
will warn the driver of a low tire pressure based
on the vehicle recommended cold placard pres-
sure.
The tire pressure will vary with temperature by
about 1 psi (7.0 kPa) for every 12°F (6.5°C).
This means that when the outside temperature
decreases, the tire pressure will decrease. Tire
pressure should always be set based on cold
inflation tire pressure. This is defined as the tire
pressure after a vehicle has not been driven for
more than three hours, or driven less than
1 mile (1.6 km) after a three-hour period. Refer
to "Tires – General Information" in "Starting
and Operating" for information on how to
(Continued) properly inflate the vehicle's tires. The tire
pressure will also increase as the vehicle is
driven; this is normal and there should be no
adjustment for this increased pressure.
The TPMS will warn the driver of a low tire
pressure if the tire pressure falls below the low
pressure warning threshold for any reason,
including low temperature effects, or natural
pressure loss through the tire.
The TPMS will continue to warn the driver of low
tire pressure as long as the condition exists,
and will not turn off until the tire pressure is at or
above recommended cold placard pressure.
Once the "Tire Pressure Monitoring Telltale
Light" has been illuminated, the tire pressure
must be increased to the recommended cold
placard pressure in order for the "Tire Pressure
Monitoring Telltale Light" to be turned OFF.
NOTE:
When filling warm tires, the tire pressure
may need to be increased up to an additional
4 psi (30 kPa) above the recommended cold
placard pressure in order to turn the Tire
Pressure Monitoring Telltale Light off.
