display CHRYSLER PACIFICA 2007 1.G Repair Manual

NOTE:Your vehicle is equipped with a compact spare
wheel and tire assembly that does not have a tire pressure
monitoring sensor. Therefore, it will not be monitored by
the Tire Pressure Monitoring System. In the event that a
compact spare tire is used to replace a low pressure road
tire, the next ignition key cycle will still show the Tire
Pressure Monitoring Lamp to be ON, a Chime will
sound, and the Electronic Vehicle Information Center
(EVIC) will still show the low tire pressure value flashing
on the graphic display. This sequence will repeat for
every key cycle until the original Tire Pressure Monitor-
ing System (TPMS) tire has been properly repaired (or
replaced) and put back on the vehicle in place of the
compact spare tire.CAUTION!
The Tire Pressure Monitoring System (TPMS) has
been optimized for the original equipment tires and
wheels. TPMS pressures have been established for
the tire size equipped on your vehicle. Undesirable
system operation or sensor damage may result when
using replacement equipment that is not of the same
size, type, and/or style. After-market 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.

•Tighten the fuel filler cap until you hear a “clicking”
sound. This is an indication that the fuel filler cap is
properly tightened.
•If the gas cap is not tighten properly, the Malfunction

ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated onboard
diagnostic system called OBD II. This system monitors
the performance of the emissions, engine, and automatic
transmission control systems. When these systems are
operating properly, your vehicle will provide excellent
performance and fuel economy, as well as engine emis-
sions well within current government regulations.
If any of these systems require service, the OBD II system
will turn on the “Malfunction Indicator Light.” It will
also store diagnostic codes and other information to
assist your service technician in making repairs. Al-
though your vehicle will usually be drivable and not
need towing, see your dealer for service as soon as
possible.CAUTION!
•Prolonged driving with the “Malfunction Indica-
tor Light” on could cause further damage to the
emission control system. It could also affect fuel
economy and driveability. The vehicle must be
serviced before any emissions tests can be per-
formed.
•If the “Malfunction Indicator Light” is flashing
while the engine is running, severe catalytic con-
verter damage and power loss will soon occur.
Immediate service is required.
Loose Fuel Filler Cap Message
After fuel is added, the vehicle diagnostic system can
determine if the fuel filler cap is loose, improperly
installed, or damaged. A loose fuel filler cap message will
be displayed in the instrument cluster. Tighten the gas
