wheel CHRYSLER PACIFICA 2008 1.G Service Manual

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 TPMS consists of the following components:
²Receiver Module
²4 Tire Pressure Monitoring Sensors
²3 Trigger Modules (mounted in three of the four wheel
wells)
²Various TPMS Messages, which display in the Elec-
tronic Vehicle Information Center (EVIC), and a
graphic displaying tire pressures.
²Yellow Tire Pressure Monitoring Telltale Light
Tire Pressure Monitoring Low Pressure Warnings
The 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. The EVIC will show a graphic display of the
pressure value(s) with the low tire(s) flashing.

If the ignition key is cycled, this sequence will repeat,
providing the system fault still exists If the system fault
no longer exists, the TPMS Telltale Light will no longerflash, theªSERVICE TIRE SYSTEM SOONºtext mes-
sage will not be present, and a pressure value will be
displayed instead of dashes. 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:
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.

Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, and cargo. The total
load must be limited so that you do not exceed the
GVWR.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front and rear
axles. Distribute the load over the front and rear axles
evenly. Make sure that you do not exceed either front or
rear GAWR.
WARNING!
Because the front wheels drive and steer the vehicle,
it is important that you do not exceed the maximum
front or rear GAWR. A dangerous driving condition
can result if either rating is exceeded. You could lose
control of the vehicle and have an accident.
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.
332 STARTING AND OPERATING

Trailer and Tongue Weight
Always load a trailer with 60% to 65% of the weight in
the front of the trailer. This places 10% to 15% of the
Gross Trailer Weight (GTW) on the tow hitch of your
vehicle. Loads balanced over the wheels or heavier in the
rear can cause the trailer to swayseverelyside to side
which will cause loss of control of the vehicle and trailer.
Failure to load trailers heavier in front is the cause of
many trailer accidents.
Never exceed the maximum tongue weight stamped on
your bumper or trailer hitch.
Consider the following items when computing the
weight on the rear axle of the vehicle:
²The tongue weight of the trailer.
²The weight of any other type of cargo or equipment
put in or on your vehicle.
²The weight of the driver and all passengers.

WARNING!
Improper towing can lead to an injury accident.
Follow these guidelines to make your trailer towing
as safe as possible:
Make certain that the load is secured in the trailer
and will not shift during travel. When trailering
cargo that is not fully secured, dynamic load shifts
can occur that may be difficult for the driver to
control. You could lose control of your vehicle and
have an accident.
²When hauling cargo or towing a trailer, do not over-
load your vehicle or trailer. Overloading can cause a
loss of control, poor performance or damage to brakes,
axle, engine, transmission, steering, suspension, chas-
sis structure or tires.
²Safety chains must always be used between your
vehicle and trailer. Always connect the chains to the
frame or hook retainers of the vehicle hitch. Cross the
chains under the trailer tongue and allow enough
slack for turning corners.
²Vehicles with trailers should not be parked on a grade.
When parking, apply the parking brake on the tow
vehicle. Put the tow vehicle automatic transmission in
P for Park. Always, block or9chock9the trailer wheels.
²GCWR must not be exceeded.
²Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
1. GVWR
2. GTW
3. GAWR

Towing Tips Ð Electronic Speed Control (If
Equipped)
þ
Don't use in hilly terrain or with heavy loads.
þWhen using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
þUse speed control in flat terrain and with light loads to
maximize fuel efficiency.
Towing Tips Ð Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
þCity Driving
When stopped for short periods of time, put transmission
in neutral but do not increase engine idle speed.
þHighway Driving
Reduce speed.
þAir Conditioning
Turn off temporarily.
þrefer to Cooling System Operating information in the
Maintenance section of this manual for more informa-
tion.

CAUTION!
The winch mechanism is designed for use with the
jack handle only. Use of an air wrench or other power
tools is not recommended and can damage the winch.
When the spare is clear, tilt the retainer at the end of the
cable and pull it through the center of the wheel.
Preparations For Jacking
Park the vehicle on a firm level surface, avoid ice or
slippery areas,set the parking brakeand place the gear
selector in PARK. Turn OFF the ignition.
WARNING!
Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off
the road to avoid the danger of being hit when
operating the jack or changing the wheel.
²Turn on the Hazard Warning Flasher.
²Block both the front and rear
of the wheel diagonally oppo-
site the jacking position. For
example, if changing the right
front tire, block the left rear
wheel.
²Passengers should not remain in the vehicle when the
vehicle is being jacked.

Jacking Instructions
WARNING!
²Getting under a jacked-up vehicle is dangerous.
The vehicle could slip off the jack and fall on you.
You could be crushed. Never get any part of your
body under a vehicle that is on a jack. Never start
or run the engine while the vehicle is on a jack. If
you need to get under a raised vehicle, take it to a
service center where it can be raised on a lift.
²The jack is designed to use as a tool for changing
tires only. The jack should not be used to lift the
vehicle for service purposes. The vehicle should
be jacked on a firm level surface only. Avoid ice or
slippery areas.
WARNING!
Carefully follow these tire changing warnings to help pre-
vent personal injury or damage to your vehicle:
²Always park on a firm, level surface as far from the edge
of the roadway as possible before raising the vehicle.
²Block the wheel diagonally opposite the wheel to be
raised.
²Apply the parking brake firmly before jacking.
²Never start the engine with the vehicle on a jack.
²Do not let anyone sit in the vehicle when it is on a jack.
²Do not get under the vehicle when it is on a jack.
²Only use the jack in the positions indicated.
²If working on or near a roadway, be extremely careful of
motor traffic.
²To assure that spare tires, flat or inflated are securely
stowed, spares must be stowed with the value stem
facing the ground.
