2008 CHRYSLER PACIFICA four wheel drive

ELECTRONIC BRAKE CONTROL SYSTEM -
ABS/TCS/BAS/ESP
Your vehicle is equipped with the advanced electronic
brake control system that includes Anti-Lock Brake Sys-
tem (ABS), Traction Control System (TCS) Brake Assist
System (BAS), and Electronic Stability Program (ESP). All
four systems work together to enhance vehicle stability
and control in various driving conditions, and are com-
monly referred to as ESP.
Traction Control System (TCS)
This system monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, brake
pressure is applied to the slipping wheel(s) and engine
power is reduced to provide enhanced acceleration and
stability. A feature of the TCS system functions similar to
a limited slip differential and controls the wheel spin
across a driven axle. If one wheel on a driven axle is
spinning faster than the other, the system will apply thebrake of the spinning wheel. This will allow more engine
torque to be applied to the wheel that is not spinning.
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle's braking
capability during emergency braking maneuvers. The
system detects an emergency braking situation by sens-
ing the rate and amount of brake application and then
applies optimum pressure to the brakes. This can help
reduce braking distances. The BAS complements the
anti-lock brake system (ABS). Applying the brakes very
quickly results in the best BAS assistance. To receive the
benefit of the system, you must apply continuous brak-
ing pressure during the stopping sequence. Do not
reduce brake pedal pressure unless braking is no longer
desired. Once the brake pedal is released, the BAS is
deactivated.
154 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

Tire Pressures for High Speed Operation
The manufacturer advocates driving at safe speeds
within posted speed limits. Where speed limits or condi-
tions are such that the vehicle can be driven at high
speeds, maintaining correct tire inflation pressure is very
important. Increased tire pressure and reduced vehicle
loading may be required for high-speed vehicle opera-
tion. Refer to original equipment or an authorized tire
dealer for recommended safe operating speeds, loading
and cold tire inflation pressures.
WARNING!
High speed driving with your vehicle under maxi-
mum load is dangerous. The added strain on your
tires could cause them to fail. You could have a
serious accident. Don't drive a vehicle loaded to the
maximum capacity at continuous speeds above 75
mph (120 km/h).
Radial-Ply Tires
WARNING!
Combining radial ply tires with other types of tires
on your vehicle will cause your vehicle to handle
poorly. The instability could cause an accident. Al-
ways use radial ply tires in sets of four (or 6, in case
of trucks with dual rear wheels). Never combine
them with other types of tires.
Cuts and punctures in radial tires are repairable only in
the tread area because of sidewall flexing. Consult your
authorized tire dealer for radial tire repairs.
306 STARTING AND OPERATING

Improper alignment will not cause vehicle vibration.
Vibration may be a result of tire and wheel out-of-
balance. Proper balancing will reduce vibration and
avoid tire cupping and spotty wear.
TIRE CHAINS
Use only compact chains, or other traction aids that meet
SAE type ªClass Sº specifications. Chains must be the
proper size for the vehicle, as recommended by the chain
manufacturer.
NOTE:Do not use tire chains on a compact spare tire.
CAUTION!
To avoid damage to your vehicle or tires, observe the following
precautions:
²Because of restricted chain clearance between tires and other
suspension components, it is important that only chains in
good condition are used. Broken chains can cause serious
damage. Stop the vehicle immediately if noise occurs that
could indicate chain breakage. Remove the damaged parts of
the chain before further use.
²Install chains on the front wheels as tightly as possible and
then retighten after driving about
1¤2mile (0.8 km).
²Do not exceed 45 mph (70 km/h).
²Drive cautiously and avoid severe turns and large bumps,
especially with a loaded vehicle.
²If chains are used on an All Wheel Drive (AWD) vehicle, they
should be used on all four tires.
²Do not drive for prolonged period on dry pavement.
²Observe the tire chain manufacturer's instructions on the
method of installation, operating speed, and conditions for
use. Always use the lower suggested operating speed of the
chain manufacturer if different than the speed recommended
by the manufacture.
312 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.
318 STARTING AND OPERATING

Basic TPMS with 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
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
above 15 mph (25 km/h) for the TPMS to receive this
information.
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. In
addition, EVIC will display a ªSERVICE TIRE SYSTEM
SOONº text message. If the ignition key is cycled, this

sequence will repeat, providing 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 scenarios:
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 bythe 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, a chime to
sound, and a ª1 Tire Low Pressureº message to appear in
the EVIC. 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.
Premium TPMS ± 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.
320 STARTING AND OPERATING

NOTE:
²Your 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 compact spare tire is
swapped with a low pressure road tire, each ignition
key cycle will still show the TPMS Lamp to be ON, a
chime to sound, and the EVIC will still show the low
tire pressure value flashing on the graphic display.
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. 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. In addition, the graphic display
in the EVIC will update with a new pressure value.
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.
