automatic transmission CHRYSLER PACIFICA 2007 1.G User Guide

You can shift in or out of the AutoStick mode at any time
without taking your foot off the accelerator pedal. If you
choose the Overdrive mode, the transmission will oper-
ate automatically; shifting between the four available
gears. When you wish to engage AutoStick, simply move
the shift lever to the AUTOSTICK position. The transmis-
sion will remain in the current gear until an upshift or
downshift is chosen.
Move the lever back to the Overdrive position to shift out
of the AutoStick mode.
AutoStick General Information
•
The transmission will automatically upshift from first
to second gear and from second to third gear when
engine speed reaches about 6300 RPM.
•Downshifts from third to second gear above 74 mph
(119 km/h) and from second to first gear above 41
mph (66 km/h) will be ignored.
•You can start out in first, second, or third gear. Shifting
into fourth gear can occur only after vehicle speed
reaches 15 mph (24 km/h).
•The transmission will automatically downshift to first
gear when coming to a stop.
•Starting out in third gear is helpful in snowy or icy
conditions.
•While in the AutoStick mode, Speed Control will only
function in third or fourth gear.
Downshifting out of third gear will turn off the speed
control.
•If the system detects powertrain overheating, the
transmission will revert to the automatic shift mode
and remain in that mode until the powertrain cools off.

•If the system detects a problem it will disable the
AutoStick mode and the transmission will return to
the automatic mode until the problem is corrected.
ALL WHEEL DRIVE — IF EQUIPPED
This feature provides full time, on-demand, All Wheel
Drive (AWD). The system is automatic with no driver
inputs or additional driving skills required. Under nor-
mal driving conditions, the front wheels provide most of
the traction. If the front wheels begin to lose traction,
power is shifted automatically to the rear wheels. The
greater the front wheel traction loss, the greater the
power transfer to the rear wheels.
CAUTION!
All wheels must have the same size and type tires.
Unequal tire sizes must not be used. Unequal tire
size may cause failure of the power transfer unit.
PARKING BRAKE
When the parking brake is applied with the ignition
switch on, the brake light in the instrument cluster will
turn on.
NOTE:This light only shows that the parking brake is
applied. It does not show the degree of brake application.
276 STARTING AND OPERATING

WARNING!
•Always fully apply the parking brake when leav-
ing your vehicle, or it may roll and cause damage
or injury. Also be certain to leave an automatic
transmission in Park, a manual transmission in
Reverse or first gear. Failure to do so may allow
the vehicle to roll and cause damage or injury.
•NEVER leave children alone in a vehicle. Leaving
children in a vehicle unattended is dangerous for
a number of reasons. A child or others could be
seriously or fatally injured. Don’t leave the keys
in the ignition. A child could operate power
windows, other controls, or move the vehicle
•Be sure the parking brake is fully disengaged
before driving, failure to do so can lead to brake
problems due to excessive heating of the rear
brakes.
BRAKE SYSTEM
In the event power assist is lost for any reason (for
example, repeated brake applications with the engine
off), the brakes will still function. The effort required to
brake the vehicle will be much greater than that required
with the power system operating.
Your vehicle is equipped with dual hydraulic
brake systems. If either of the two hydraulic
systems lose normal capability, the remaining
system will still function. There will be some
loss of overall braking effectiveness. This may be evident
by increased pedal travel during application, greater
pedal force required to slow or stop, and potential
activation of the Brake Warning Lamp.
278 STARTING AND OPERATING

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.
•When 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.
•Safety 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.
•Vehicles 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 orchockthe trailer wheels.
•GCWR must not be exceeded.
•Total 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 — 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.

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.
354 WHAT TO DO IN EMERGENCIES

Check the Battery Test Indicator (if equipped). If a light or
bright colored dot is visible in the indicator (if equipped),
DO NOT jump-start the battery.
If the indicator (if equipped) is dark or shows a green dot,
proceed as follows:
1. Wear eye protection and remove any metal jewelry
such as watch bands or bracelets that might make an
inadvertent electrical contact.
2. When boost is provided by a battery in another
vehicle, park that vehicle within booster cable reach and
without letting the vehicles touch. Set the parking brake,
place the automatic transmission in PARK and turn the
ignition switch to the OFF position for both vehicles.
3. Turn off the heater, radio and all unnecessary electrical
loads.4. Connect one end of a jumper cable to the positive
terminal of the discharged battery. Connect the other end
of the same cable to the positive terminal of the booster
battery.
WARNING!
Do not permit vehicles to touch each other as this
could establish a ground connection and personal
injury could result.
5. Connect the other cable, first to the negative terminal
of the booster battery andthen to the engine of the
vehicle with the discharged battery.Make sure you have
a good contact on the engine.

and rear wheels must be on the ground. If your vehicle
must be towed farther or at a higher rate of speed, it must
be transported on a flat bed truck.
All Transmissions
CAUTION!
•Do not attempt to tow this vehicle from the front
with sling type towing equipment. Damage to the
front fascia will result.
•Always use wheel lift equipment when towing
from the front. The only other approved method
of towing is with a flat bed truck.
•Do not tow the vehicle from the rear. Damage to
the rear sheet metal, liftgate and fascia will occur.
•Do not push or tow this vehicle with another
vehicle as damage to the bumper fascia and trans-
mission may result.
If it is necessary to use the accessories while being towed
(wipers, defrosters, etc.), the key must be in the ON
position, not the ACCESSORY position. Make certain the
transmission remains in NEUTRAL.
Without The Ignition Key
Special care must be taken when the vehicle is towed
with the ignition in the LOCK position. The only ap-
proved method of towing with out the ignition key is
with a flat bed truck. Proper towing equipment is neces-
sary to prevent damage to the vehicle.
TOWING THIS VEHICLE BEHIND ANOTHER
VEHICLE (Flat towing with all four wheels on the
ground)
Flat towing of vehicles equipped with an automatic
transmission, is only permitted within the limitations
described in this section.

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
