2008 CHRYSLER PACIFICA sensor

Dual-Zone Automatic Temperature Control
The Dual Zone Automatic Temperature Control (ATC)
System automatically maintains the interior comfort level
desired by the driver and front seat passenger. This is
accomplished by using two infrared sensors located in
the center of the instrument panel. The two infrared
sensors independently measure the surface temperature
of the driver and front seat passenger. Based on the
sensor input, the system automatically adjusts the air
temperature, the airflow volume, the airflow distribu-
tion, and amount of inside air recirculation to maintain
front seat occupant comfort, even under changing out-
side weather conditions.
To operate the system, press either the9AUTO HI9or
9AUTO LO9buttons. The system now automatically
regulates the heating and air conditioning system includ-
ing blower speed, outlet air temperature, and airflow
distribution through the various outlets within the in-
strument panel. Using the9TEMP9buttons, adjust the

CAUTION!
The 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 equip-
ment that is not of the same size, type, and/or style.
Aftermarket wheels can cause sensor damage. Do not
use aftermarket sealants or balance beads if your
vehicle is equipped with a TPMS, as damage to the
sensors may result.
CAUTION!
After inspecting or adjusting the tire pressure, al-
ways reinstall the valve stem cap. This will prevent
moisture and dirt from entering the valve stem,
which could damage the TPMS sensor.
NOTE:
²The TPMS is not intended to replace normal tire care
and maintenance, or to provide warning of a tire
failure or condition.
²The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
²Driving 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.
316 STARTING AND OPERATING

²The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver's responsibility to maintain
correct tire pressure, using an accurate tire pressure
gage, even if under-inflation has not reached the level
to trigger illumination of the TPMS Telltale Lamp.
²Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
Basic TPMS without EVIC Ð If Equipped
The TPMS uses wireless technology with wheel rim
mounted electronic sensors to monitor tire pressure lev-
els. Sensors, mounted to each wheel as part of the valve
stem, transmit tire pressure readings to the Receiver
Module.
NOTE:It is particularly important, for you to check the
tire pressure in all of your tires regularly and too main-
tain the proper pressure.The Basic TPMS consists of the following components:
²Receiver Module
²4 Tire Pressure Monitoring Sensors
²Tire Pressure Monitoring Telltale Lamp
The Tire Pressure Monitoring Telltale Lamp
will illuminate in the instrument cluster and an
audible chime will be activated when one or
more of the four active road tire pressures are
low. Should this occur you should stop as soon as
possible, check the inflation pressure of each tire on your
vehicle, and inflate each tire to the manufacturer recom-
mended pressure, located on the tire pressure placard.
The system will automatically update and the TPMS
warning light will extinguish once the updated tire
pressure(s) have been received.

NOTE:The vehicle may need to be driven for up to 10
minutes above 15 mph (25 km/h) to receive this infor-
mation.
The TPMS Telltale Lamp will flash on and off for 75
seconds, and remain on solid when a system fault is
detected. The system fault will also sound a chime. If the
ignition key is cycled, this sequence will repeat, provid-
ing the system fault still exists. The TPMS Telltale Lamp
will turn off when the fault condition no longer exists. A
system fault can occur with any of the following sce-
narios:
1. Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the TPMS
sensors.
2. Installing some form of aftermarket window tinting
that affects radio wave signals.3. Accumulation of excessive snow and/or ice around
the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPMS sensors.
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 TPMS. In the event that the compact spare tire is
swapped with a low pressure road tire, each ignition key
cycle will still show the TPMS Lamp to be ON, and a
chime to sound. Once you repair or replace the original
road tire and reinstall it on the vehicle in place of the
compact spare tire, the TPMS will update automatically,
and the TPMS Lamp will turn OFF 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 10 minutes above 15 mph (25 km/h) for
the TPMS to receive this information.

²Various TPMS Messages, which display in the Elec-
tronic Vehicle Information Center (EVIC).
²Tire Pressure Monitoring Telltale LampThe TPMS Telltale Lamp will illuminate in the instru-
ment cluster, and an audible chime will be activated
when one or more of the four active road tire pressures
are low. In addition, EVIC will display the number of
tire(s) that are low, followed by the ªTire Low Pressureº
text message. Should this occur, you should stop as soon
as possible, check the inflation pressure of each tire on
you vehicle, and inflate each tire to the vehicle's recom-
mended cold placard pressure value. The system will
automatically update and the TPMS Lamp will extin-
guish one the updated tire pressures have been received.
The vehicle may need to be driven for up to 10 minutes

NOTE:Low pressure in the spare or compact tire
(which has no sensor and therefore not monitored) will
not cause the TPMS Telltale Lamp to illuminate or the
chime to sound.
Should a low tire condition occur on any of the four
active road tire(s), you should stop as soon as possible,
and inflate the low tire(s) that is flashing on the graphic
display to the vehicle's recommended cold placard pres-
sure value. The system will automatically update, the
graphic display of the pressure value(s) will stop flash-
ing, and the TPMS Lamp will extinguish once the up-
dated tire pressure(s) have been received. The vehicle
