2007 CHRYSLER PACIFICA air condition

All Wheel Drive (AWD) — If Equipped
Under normal operating conditions, periodic fluid level
checks and lubricant changes for the Power Transfer Unit
and Rear Carrier, are not required. However when the
vehicle is serviced for other reasons, the exterior surface
of these components should be inspected for evidence of
fluid leaks. Confirmed leaks should be repaired as soon
as possible.
Power Transfer Unit
The fill plug is located on the side of the power transfer
unit housing. The fluid should be maintained at a level
even with the bottom of the fill plug hole when the
vehicle is parked on a level surface. If it becomes neces-
sary to add or replace the fluid, use only the manufac-
turers recommended fluid, refer to Fluids, Lubricants
and Genuine Parts for correct fluid type.
Rear Carrier
The fill plug is located on the side of the rear carrier
housing. The fluid should be maintained at a level even
with the bottom of the fill plug hole when the vehicle is
parked on a level surface. if it becomes necessary to add
or replace the fluid, use only the manufacturers recom-
mended fluid, refer to Fluids, Lubricants and Genuine
Parts for correct fluid type.
Fluid Changes
The fluid should be changed as follows:
Normal UsageNo Service Required
Severe Usage Service Required

Severe Usage is defined as:
1. More than 50% of vehicle operation in stop and go
traffic where vehicle is driven regularly for more than 45
minutes of continuous operation, such as in heavy city or
in construction zone traffic,
2. Police, taxi, limousine, commercial type operation, or
trailer towing where the vehicle driven regularly for
more than 45 minutes of continuous operation.
NOTE:Refer to Section 8 of this manual for Mainte-
nance Schedules.
Front And Rear Wheel Bearings
Front and rear wheel bearings are permanently sealed.
No regular maintenance is required for these compo-
nents.
Appearance Care and Protection from Corrosion
Protection of Body and Paint from Corrosion
Vehicle body care requirements vary according to geo-
graphic locations and usage. Chemicals that make roads
passable in snow and ice, and those that are sprayed on
trees and road surfaces during other seasons, are highly
corrosive to the metal in your vehicle. Outside parking,
which exposes your vehicle to airborne contaminants,
road surfaces on which the vehicle is operated, extreme
hot or cold weather and other extreme conditions will
have an adverse effect on paint, metal trim, and under-
body protection.
The following maintenance recommendations will enable
you to obtain maximum benefit from the corrosion
resistance built into your vehicle.
What Causes Corrosion?
Corrosion is the result of deterioration or removal of
paint and protective coatings from your vehicle.

CAUTION!
•When installing the Integrated Power Module
cover, it is important to ensure the cover is prop-
erly positioned and fully latched. Failure to do so
may allow water to get into the Integrated Power
Module, and possibly result in a electrical system
failure.
•When replacing a blown fuse, it is important to
use only a fuse having the correct amperage
rating. The use of a fuse with a rating other than
indicated may result in a dangerous electrical
system overload. If a properly rated fuse contin-
ues to blow, it indicates a problem in the circuit
that must be corrected.
VEHICLE STORAGE
If you are leaving your vehicle dormant for more than 21
days you may want to take steps to protect your battery.
You may:
•Disconnect the negative cable from the battery.
•Anytime you store your vehicle, or keep it out of
service (i.e. vacation) for two weeks or more, run the
air conditioning system at idle for about five minutes
in the fresh air and high blower setting. This will
insure adequate system lubrication to minimize the
possibility of compressor damage when the system is
started again.

The “Scheduled” maintenance services, listed inbold
typemust be done at the times or mileages specified to
assure the continued proper functioning of the emission
control system. These, and all other maintenance services
included in this manual, should be done to provide best
vehicle performance and reliability. More frequent main-
tenance may be needed for vehicles in severe operating
conditions such as dusty areas and very short trip
driving.
Inspection and service also should be done any time a
malfunction is suspected.
NOTE:Maintenance, replacement, or repair of the emis-
sion control devices and systems on your vehicle may be
performed by any automotive repair establishment or
individual using any automotive part, which has been
certified pursuant to U.S. EPA or, in the State of Califor-
nia, California Air Resources Board regulations.
MAINTENANCE SCHEDULES
There are two maintenance schedules that show the
requiredservice for your vehicle.
First is Schedule“B”. It is for vehicles that are operated
under the conditions that are listed below and at the
beginning of the schedule.

•Stop and go driving.
•Extensive engine idling.
•Driving in dusty conditions.
•Short trips of less than 10 miles (16 km).
