fuel CHRYSLER PACIFICA 2007 1.G Owner's Manual

For best results, a refueling pattern that alternates be-
tween E-85 and unleaded gasoline should be avoided.
When you do switch fuels, it is recommended that
•you do not switch when the fuel gauge indicates less
than 1/4 full
•you do not add less than 5 gallons when refueling
•you operate the vehicle immediately after refueling for
a period of at least 5 minutes
Observing these precautions will avoid possible hard
starting and/or significant deterioration in drivability
during warm up.
NOTE:When the ambient temperature is above 90°F,
you may experience hard starting and rough idle follow-
ing start up even if the above recommendations are
followed.
Selection Of Engine Oil For Flexible Fuel Vehicles
(E-85) and Gasoline Vehicles
Whether operating the vehicle on an E-85 ethanol fuel or
unleaded gasoline the engine oil requirements are the
same. Refer to the “Maintenance Procedures” section of
this manual for the proper quality and viscosity engine
oil.
Starting
The characteristics of E-85 fuel make it unsuitable for use
when ambient temperatures fall below 0°F. In the range
of 0°F to 32°F, you may experience an increase in the time
it takes for your engine to start, and a deterioration in
drivability (sags and/or hesitations) until the engine is
fully warmed up.
STARTING AND OPERATING 325

Cruising Range
Because E-85 fuel contains less energy per gallon than
gasoline, you will experience an increase in fuel con-
sumption. You can expect your MPG and your driving
range to decrease by about 30% compared to gasoline
operation.
Replacement Parts
Many components in your Flexible Fuel Vehicle (FFV) are
designed to be compatible with ethanol. Always be sure
that your vehicle is serviced with correct ethanol com-
patible parts.
CAUTION!
Replacing fuel system components with non-ethanol
compatible components can damage your vehicle.
Maintenance
If you operate the vehicle using E-85 fuel, follow Sched-
ule B in the maintenance schedule section of this manual.
CAUTION!
Do not use ethanol mixture greater than 85% in your
vehicle. It will cause difficulty in cold starting and
may affect driveability.
VEHICLE LOADING
The load carrying capacity of your vehicle is shown in the
charts that follow. This information should be used for
passenger and luggage loading as indicated.
If the seatbacks are folded for carrying cargo, do not
exceed the specified GVWR and GAWR.
326 STARTING AND OPERATING

Towing Tips — Automatic Transmission
The “D” range can be selected when towing. However, if
frequent shifting occurs while in this range, the “3” range
should be selected.
NOTE:Using the “3” range while operating the vehicle
under heavy operating conditions will improve perfor-
mance and extend transmission life by reducing exces-
sive shifting and heat build up. This action will also
provide better engine braking.
The automatic transmission fluid and filter should be
changed if you REGULARLY tow a trailer for more than
45 minutes of continuous operation. See Schedule “B” in
section 8 of this manual for transmission fluid change
intervals.
NOTE:Check the automatic transmission fluid level
before towing.
Towing Tips — Electronic Speed Control (If
Equipped)

Don’t use in hilly terrain or with heavy loads.
When 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.
Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
Towing Tips — Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
City Driving
When stopped for short periods of time, put transmission
in neutral but do not increase engine idle speed.
STARTING AND OPERATING 341

NOTE:When reinstalling the wheel center cap, insure
that the valve stem symbol on the back of the cap is
pointed toward the wheel valve stem. Install the center
cap using hand pressure only. Do not use a hammer.
Wheel Nuts
All wheel nuts should be tightened occasionally to elimi-
nate the possibility of wheel studs being sheared or the
bolt holes in the wheels becoming elongated. This is
especially important during the first few hundred miles
of operation, and after each time a tire is changed, to
allow the wheel nuts to become properly set. All nuts
should first be firmly seated against the wheel. The nuts
should then be tightened to recommended torque.
Tighten the nuts to final torque in increments. Progress
around the bolt circle, tightening the nut opposite to the
nut just previously tightened until final torque is
achieved. Recommended torque is 130 N·m (95 ft. lbs).
JUMP-STARTING PROCEDURE
WARNING!
•Do not attempt to push or tow your vehicle to get it started.
Vehicles equipped with an automatic transmission cannot be
started this way. Unburned fuel could enter the catalytic
converter and once the engine has started, ignite and damage
the converter and vehicle. If the vehicle has a discharged
battery, booster cables may be used to obtain a start from
another vehicle. This type of start can be dangerous if done
improperly, so follow this procedure carefully.
•Battery fluid is a corrosive acid solution; do not allow battery
fluid to contact eyes, skin or clothing. Don’t lean over battery
when attaching clamps or allow the clamps to touch each other.
If acid splashes in eyes or on skin, flush contaminated area
immediately with large quantities of water.
•A battery generates hydrogen gas which is flammable and
explosive. Keep flame or spark away from the vent holes. Do
not use a booster battery or any other booster source with an
output that exceeds 12 volts.
•Take care to avoid the radiator cooling fan whenever the hood
is raised. It can start anytime the ignition switch is on. You can
be hurt by the fan.

ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated onboard
diagnostic system called OBD II. This system monitors
the performance of the emissions, engine, and automatic
transmission control systems. When these systems are
operating properly, your vehicle will provide excellent
performance and fuel economy, as well as engine emis-
sions well within current government regulations.
If any of these systems require service, the OBD II system
will turn on the “Malfunction Indicator Light.” It will
also store diagnostic codes and other information to
assist your service technician in making repairs. Al-
though your vehicle will usually be drivable and not
need towing, see your dealer for service as soon as
possible.CAUTION!
•Prolonged driving with the “Malfunction Indica-
tor Light” on could cause further damage to the
emission control system. It could also affect fuel
economy and driveability. The vehicle must be
serviced before any emissions tests can be per-
formed.
•If the “Malfunction Indicator Light” is flashing
while the engine is running, severe catalytic con-
verter damage and power loss will soon occur.
Immediate service is required.
Loose Fuel Filler Cap Message
After fuel is added, the vehicle diagnostic system can
determine if the fuel filler cap is loose, improperly
installed, or damaged. A loose fuel filler cap message will
be displayed in the instrument cluster. Tighten the gas
366 MAINTAINING YOUR VEHICLE

DEALER SERVICE
Your dealer has the qualified service personnel, special
tools, and equipment to perform all service operations in an
expert manner. Service Manuals are available which include
detailed service information for your vehicle. Refer to these
manuals before attempting any procedure yourself.
NOTE:Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
WARNING!
You can be badly injured working on or around a
motor vehicle. Only do service work for which you
have the knowledge and the proper equipment. If you
have any doubt about your ability to perform a service
job, take your vehicle to a competent mechanic.
MAINTENANCE PROCEDURES
The pages that follow contain therequiredmaintenance
services determined by the engineers who designed your
vehicle.
Besides the maintenance items for which there are fixed
maintenance intervals, there are other items that should
operate satisfactorily without periodic maintenance.
However, if a malfunction of these items does occur, it
could adversely affect the engine or vehicle performance.
These items should be inspected if a malfunction is
observed or suspected.
Engine Oil
Checking Oil Level
To assure proper engine lubrication, the engine oil must
be maintained at the correct level. Check the oil level at
regular intervals, such as every fuel stop.
MAINTAINING YOUR VEHICLE 369

Engine Oil Viscosity (SAE Grade) — 3.8 Liter
Engines
SAE 5W-20 engine oil is recommended for all operating
temperatures. This engine oil improves low temperature
starting and vehicle fuel economy. Your engine oil filler
cap also shows the recommended engine oil viscosity for
your vehicle.
For information on engine oil filler cap location, refer to
the Engine Compartment illustration in this section.
Lubricants which do not have both, the engine oil certi-
fication mark and the correct SAE viscosity grade num-
ber should not be used.
Synthetic Engine Oils
There are a number of engine oils being promoted as
either synthetic or semi-synthetic. If you chose to use
such a product, useonlythose oils that are AmericanPetroleum Institute (API) Certified and have the recom-
mended SAE viscosity grade. Follow the maintenance
schedule that describes your driving type.
Materials Added to Engine Oil
The manufacture strongly recommends against the addi-
tion of any additives (other than leak detection dyes) to
the engine oil. Engine oil is an engineered product and
it’s performance may be impaired by supplemental ad-
ditives.
Disposing of Used Engine Oil And Oil Filters
Care should be taken in disposing of used engine oil and
oil filters from your vehicle. Used oil and oil filters,
indiscriminately discarded, can present a problem to the
environment. Contact your dealer, service station, or
governmental agency for advice on how and where used
oil and oil filters can be safely discarded in your area.

WARNING!
The air cleaner can provide a measure of protection
in the case of engine backfire. Do not remove the air
cleaner unless such removal is necessary for repair or
maintenance. Make sure that no one is near the
engine compartment before starting the vehicle with
the air cleaner removed. Failure to do so can result in
serious personal injury.
Catalytic Converter
The catalytic converter requires the use of unleaded fuel
only. Leaded gasoline will destroy the effectiveness of the
catalyst as an emission control device.Under normal operating conditions, the catalytic con-
verter will not require maintenance. However, it is im-
portant to keep the engine properly tuned to assure
proper catalyst operation and prevent possible catalyst
damage.
CAUTION!
Damage to the catalytic converter can result if your
vehicle is not kept in proper operating condition. In
the event of engine malfunction, particularly involv-
ing engine misfire or other apparent loss of perfor-
mance, have your vehicle serviced promptly. Contin-
ued operation of your vehicle with a severe
malfunction could cause the converter to overheat,
resulting in possible damage to the converter and the
vehicle.
