tires CHRYSLER PACIFICA 2007 1.G Owner's Manual

WARNING!
•Do not use a tire, wheel size or rating other than that
specified for your vehicle. Some combinations of un-
approved tires and wheels may change suspension
dimensions and performance characteristics, resulting
in changes to steering, handling, and braking of your
vehicle. This can cause unpredictable handling and
stress to steering and suspension components. You
could lose control and have an accident resulting in
serious injury or death. Use only the tire and wheel
sizes with load ratings approved for your vehicle.
•Never use a tire with a smaller load index or capacity,
other than what was originally equipped on your
vehicle. Using a tire with a smaller load index could
result in tire overloading and failure. You could lose
control and have an accident.
•Failure to equip your vehicle with tires having ad-
equate speed capability can result in sudden tire
failure and loss of vehicle control.
CAUTION!
Replacing original tires with tires of a different size
may result in false speedometer and odometer read-
ings.
Alignment And Balance
Poor suspension alignment may result in:
•Fast tire wear.
•Uneven tire wear, such as feathering and one-sided
wear.
•Vehicle pull to right or left.
Tires may also cause the vehicle to pull to the left or right.
Alignment will not correct this condition. See your dealer
for proper diagnosis.
STARTING AND OPERATING 305

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 “Class S” 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:
•Because 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.
•Install chains on the front wheels as tightly as possible and
then retighten after driving about12mile (0.8 km).
•Do not exceed 45 mph (70 km/h).
•Drive cautiously and avoid severe turns and large bumps,
especially with a loaded vehicle.
•If chains are used on an All Wheel Drive (AWD) vehicle, they
should be used on all four tires.
•Do not drive for prolonged period on dry pavement.
•Observe 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.
306 STARTING AND OPERATING

NOTE:In order to avoid damage to tires, chains, and
your vehicle do not drive for a prolonged period of time
on dry pavement. Observe the tire chain manufacturer’s
instructions on method of installation, operating speed,
and conditions for usage.
Always use the lower suggested operating speed if both
the chain manufacturer and vehicle manufacture suggest
a maximum speed. This notice applies to all chain
traction devices, including link and cable (radial) chains.
SNOW TIRES
Some areas of the country require the use of snow tires
during winter. Standard tires are of the all season type
and satisfy this requirement as indicated by the M+S
designation on the tire side wall.
If you need snow tires, select tires equivalent in size and
type to the original equipment tires. Use snow tires only
in sets of 4, failure to do so may adversely affect the
safety and handling of your vehicle.Snow tires generally have lower speed ratings than what
was originally equipped with your vehicle and should
not be operated at sustained speeds over 75 mph (120
km/h).
TIRE ROTATION
Tires on the front and rear axles of vehicles operate at
different loads and perform different steering, driving,
and braking functions. For these reasons, they wear at
unequal rates, and tend to develop irregular wear pat-
terns.
These effects can be reduced by timely rotation of tires.
The benefits of rotation are especially worthwhile with
aggressive tread designs such as those on all season type
tires. Rotation will increase tread life, help to maintain
mud, snow, and wet traction levels, and contribute to a
smooth, quiet ride.
STARTING AND OPERATING 307
5

Follow the recommended tire rotation frequency for your
type of driving found in the “Maintenance Schedules”
Section of this manual. More frequent rotation is permis-
sible if desired. The reasons for any rapid or unusual
wear should be corrected prior to rotation being per-
formed.
The suggested rotation method is the “forward-cross”
shown in the following diagram.TIRE PRESSURE MONITOR SYSTEM — IF
EQUIPPED
•
The Tire Pressure Monitoring System (TPMS) will
warn the driver of a low tire pressure based on the
vehicle recommended cold placard pressure. (The
placard is located on the drivers side ”B” Pillar).
•The tire pressure will vary with the temperature by
about 1 psi (6.9 kPa) for every 12°F (6.5°C). This means
that when the outside temperature decreases, the tire
pressure will decrease. The tire pressure will also
increase as the vehicle is driven — this is normal and
there should be no adjustment for this increased
pressure.
NOTE:Refer toTires — General Informationin this
section for information on how to properly inflate the
vehicle’s tires.
308 STARTING AND OPERATING

•The Tire Pressure Monitoring System (TPMS) will
warn the driver of a low tire pressure if the tire
pressure falls below the low pressure warning thresh-
old for any reason, including low temperature effects.
•The Tire Pressure Monitoring System (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 placard
pressure. Once the low tire pressure warning telltale
has been illuminated, the tire pressure must be in-
creased to the recommended cold placard pressure in
order for the Tire Pressure Monitoring System warning
telltale to be turned off. The system will automatically
update and the Tire Pressure Monitoring System
warning telltale will extinguish once the updated tire
pressures 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 information.
Tire Pressure Monitoring Base System without
Electronic Vehicle Information Center (EVIC) — If
Equipped
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
monitor tire pressure levels (EXCLUDING THE SPARE
TIRE). Sensors, mounted to each wheel as part of the
valve stem, transmit tire pressure readings to the Re-
ceiver 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 Tire Pressure Monitor System (TPMS) consists of the
following components:
•Receiver Module
•4 Wheel Sensors
•Tire Pressure Monitoring Telltale Lamp

Tire Pressure Monitoring Low Pressure Warnings
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. The audible chime will sound once every ignition
cycle for each low tire condition that it detects.
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 pressure recommended by the
vehicle tire pressure placard. The system will automati-
cally update and the Tire Pressure Monitoring System
Lamp 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.NOTE:A low spare or compact tire pressure will not
cause the Tire Pressure Monitoring System Telltale Lamp
to illuminate or the chime to sound.
Base Tire Pressure Monitoring System with
Electronic Vehicle Information Center (EVIC) — If
Equipped
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
monitor tire pressure levels (EXCLUDING THE SPARE
TIRE). Sensors, mounted to each wheel as part of the
valve stem, transmit tire pressure readings to the Re-
ceiver 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.
310 STARTING AND OPERATING

Service Tire System Soon
The Tire Pressure Monitoring Telltale Lamp will flash on
and off for 60 seconds in the instrument cluster, and an
audible chime will be activated when one or more of the
four active road tire pressures are low.
In addition the Electronic Vehicle Information Center
(EVIC) will display a“SERVICE TIRE SYSTEM SOON”
text message. The flash cycle will repeat every ten
minutes, without an audible chime, until the condition no
longer exists. The flash cycle sequence will repeat and an
audible chime will sound once every ignition cycle for
each condition that it detects.
NOTE:If a temporary spare tire is in use and none of
the remaining 3 active road tire pressures are low, a
“SERVICE TIRE SYSTEM SOONtextual message will
appear in the EVIC after 10 minutes of driving,CAUTION!
The Tire Pressure Monitoring System has been op-
timized 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
TPM System, as damage to the sensors may result.

This sequence will repeat for every key cycle until the
original Tire Pressure Monitoring System tire has been
properly repaired (or replaced) and put back on the
vehicle in place of the compact spare tire.
Tire Pressure Monitoring Premium System – If
Equipped
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
monitor tire pressure levels. 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 to maintain
the proper pressure.
The Tire Pressure Monitor System (TPMS) consists of the
following components:
•Receiver Module
•4 Wheel Sensors
•Wheel Sensor Trigger Modules (mounted in three of
the four wheel wells)
•Various Tire Pressure Monitoring System Messages,
which display in the Electronic Vehicle Information
Center (EVIC)
•Yellow Tire Pressure Monitoring Telltale Light
Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring System 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. The audible chime will
sound once every ignition cycle for each condition that it
detects. In addition, the Electronic Vehicle Information
Center (EVIC) will show a graphic display of the pressure
value(s) with the low tire(s) flashing.
314 STARTING AND OPERATING

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.
316 STARTING AND OPERATING

Overloading
The load carrying components (axle, springs, tires,
wheels, etc.) of your vehicle will provide satisfactory
service as long as you do not exceed the GVWR and front
and rear GAWR.
The best way to figure out the total weight of your
vehicle is to weigh it when it is fully loaded and ready for
operation. Weigh it on a commercial scale to insure that it
is not over the GVWR.
Figure out the weight on the front and rear of the vehicle
separately. It is important that you distribute the load
evenly over the front and rear axles.
Overloading can cause potential safety hazards and
shorten useful service life. Heavier axles or suspension
components do not necessarily increase the vehicle’s
GVWR.
Loading
To load your vehicle properly, first figure out its empty
weight, axle by axle and side by side. Store heavier items
down low and be sure you distribute their weight as
evenly as possible. Stow all loose items securely before
driving. If weighing the loaded vehicle shows that you
have exceeded either GAWR, but the total load is within
the specified GVWR, you must redistribute the weight.
Improper weight distribution can have an adverse effect
on the way your vehicle steers and handles and the way
the brakes operate.
