sensor JEEP LIBERTY 2012 KK / 2.G Owner's Guide

Vehicles With Compact Spare
1. The compact spare tire does not have a tire pressure
monitoring sensor. Therefore, the TPMS will not monitor
the pressure in the compact spare tire.
2. If you install the compact spare tire in place of a road
tire that has a pressure below the low-pressure warning
limit, upon the next ignition key cycle, the “TPMS Telltale
Light” will remain on and a chime will sound. In
addition, the graphic in the EVIC will still display a
flashing pressure value.
3. After driving the vehicle for up to 20 minutes above
15 mph (24 km/h), the “TPMS Telltale Light” will flash
on and off for 75 seconds and then remain on solid. In
addition, the EVIC will display a “SERVICE TPM SYS-
TEM” message for five seconds and then display dashes
(- -) in place of the pressure value.4. For each subsequent ignition key cycle, a chime will
sound, the “TPMS Telltale Light” will flash on and off for
75 seconds and then remain on solid, and the EVIC will
display a “SERVICE TPM SYSTEM” message for five
seconds and then display dashes (- -) in place of the
pressure value.
5. Once you repair or replace the original road tire and
reinstall it on the vehicle in place of the compact spare,
the TPMS will update automatically. In addition, the
“TPMS Telltale Light” will turn off and the graphic in the
EVIC will display a new pressure value instead of dashes
(- -), as long as no tire pressure is below the low-pressure
warning limit in any of the four active road tires. The
vehicle may need to be driven for up to 20 minutes above
15 mph (24 km/h) in order for the TPMS to receive this
information.

FUEL REQUIREMENTS
All engines are designed to meet all emis-
sions regulations and provide excellent
fuel economy and performance when us-
ing high quality unleaded “regular” gaso-
line having an octane rating of 87. The use
of premium gasoline is not recommended,
as it will not provide any benefit over regular gasoline in
these engines.
Light spark knock at low engine speeds is not harmful to
your engine. However, continued heavy spark knock at
high speeds can cause damage and immediate service is
required. Poor quality gasoline can cause problems such
as hard starting, stalling, and hesitations. If you experi-
ence these symptoms, try another brand of gasoline
before considering service for the vehicle.
