Tire Pressure Monitor System (Tpms) - Jeep grand cherokee 2016 Operating Information Manual

Refer to the "Service and Warranty Handbook"
for the proper maintenance intervals. More fre-
quent rotation is permissible if desired. The
reasons for any rapid or unusual wear should
be corrected prior to rotation being performed.
NOTE:
The premium Tire Pressure Monitor System
will automatically locate the pressure values
displayed in the correct vehicle position
following a tire rotation.
The suggested rotation method is the "forward-
cross" shown in the following diagram.

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 tire placard
pressure.
The tire pressure will vary with temperature by
about 1 psi (7 kPa) for every 12°F (6.5°C). This
means that when the outside temperature de-
creases, 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 the vehicle has not been driven
for at least 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
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 tire placard pressure.
Once the low tire pressure warning has been
illuminated, the tire pressure must be increased
to the recommended cold tire 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.
The system will automatically update and the
Tire Pressure Monitoring Telltale Light will extin-
guish once the updated tire pressures have
been received. The vehicle may need to be
driven for up to 20 minutes above 15 mph
(24 km/h) to receive this information.
