2007 CHRYSLER PACIFICA transmission

•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

Before leaving the vehicle, make sure that the parking
brake is fully applied and place the gear selector in the
Park position. To release the parking brake, pull out on
the parking brake release located on the left side of the
instrument panel.When parking on a hill, it is important to set the parking
brake before placing the gear selector in Park, otherwise
the load on the transmission locking mechanism may
make it difficult to move the selector out of park. As an
added precaution, turn the front wheels toward the curb
on a downhill grade and away from the curb on a uphill
grade.
The parking brake should always be applied when the
driver is not in the vehicle.

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.

334 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.
STARTING AND OPERATING 341

NOTE:With extended use, the Hazard Warning Flash-
ers may wear down your battery.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate ac-
tion.
•On the highways — Slow down.
•In city traffic — While stopped, put transmission in
neutral, but do not increase engine idle speed.
NOTE:There are steps that you can take to slow down
an impending overheat condition. If your air conditioner
is on, turn it off. The air conditioning system adds heat to
the engine cooling system and turning off the A/C
removes this heat. You can also turn the Temperature
control to maximum heat, the Mode control to floor, andthe fan control to High. This allows the heater core to act
as a supplement to the radiator and aids in removing heat
from the engine cooling system.
CAUTION!
Driving with a hot cooling system could damage
your vehicle. If temperature gauge reads “H”, pull
over and stop the vehicle. Idle the vehicle with the
air conditioner turned off until the pointer drops
back into the normal range. If the pointer remains on
the “H”, turn the engine off immediately, and call for
service.
WHAT TO DO IN EMERGENCIES 345

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.
