2007 CHRYSLER PT CRUISER ECU

Four Speed Automatic Transaxle
The electronically controlled transaxle provides a precise
shift schedule. The transaxle electronics are self calibrat-
ing; therefore, the first few shifts on a new vehicle may be
somewhat abrupt. This is a normal condition, and preci-
sion shifts will develop within a few shift cycles.
Reset Mode
The transaxle is monitored electronically for abnormal
conditions. If a condition is detected that could cause
damage, the transaxle shifts automatically into second
gear. The transaxle remains in second gear despite the
forward gear selected. Park (P), Reverse (R), and Neutral
(N) will continue to operate. This second gear limp-in
feature allows the vehicle to be driven to a dealer for
service without damaging the transaxle.
In the event that the problem has been momentary, the
transaxle can be reset to regain all forward gears.
Stop the vehicle and shift into Park (P).Turn the Key to OFF then restart the engine.
Shift into D and resume driving.
NOTE:Even if the transaxle can be reset, it is recom-
mended that you visit a dealer at your earliest possible
convenience. Your dealer has diagnostic equipment to
determine if the problem could recur.
If the transaxle cannot be reset, dealer service is required.
Gear Ranges For Four Speed Automatic
Transaxle
DO NOT race the engine when shifting from PARK or
NEUTRAL positions into another gear range.
ªPº Park
Supplements the parking brake by locking the transmis-
sion. The engine can be started in this range. Never use P
(Park) while the vehicle is in motion. Apply the parking

brake when leaving the vehicle in this range. Always
apply the parking brake first, and then place the selector
in P (Park) position.
WARNING!
Unintended movement of a vehicle could injure
those in and near the vehicle. As with all vehicles,
you should never exit a vehicle while the engine is
running. Before exiting a vehicle, you should always
shift the vehicle into P (Park), remove the key from
the ignition, and apply the parking brake. Once the
key is removed from the ignition, the transmission
shift lever is locked in the P (Park) position, securing
the vehicle against unwanted movement. Further-
more, you should never leave children unattended
inside a vehicle.
The following indicators should be used to ensure that
you have engaged the transmission shift lever into the P
(Park) position:
²When shifting into P (Park), depress the button on the
shift lever and firmly move the lever all the way
forward until it stops.
²Look at the shift indicator window on the console to
ensure it is in the P (Park) position.
²When engaged in P (Park), you will not be able to
move the shifter rearward without depressing the shift
lever button.
286 STARTING AND OPERATING

CAUTION!
²Avoid towing a trailer for the first 500 miles (805
km) of vehicle operation. Doing so may damage
your vehicle.
²During the first 500 miles (805 km) of trailer
towing, limit your speed to 50 mph (80 km/h).
Perform the maintenance listed in Section 8 of this
manual. When towing a trailer, never exceed the GAWR,
or GCWR, ratings.
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.

3. There are two front jacking locations on each side of
the body and rear jacking locations located on the trailing
arm bracket under the triangular cut out symbol. Turn
the jack screw to the right until the jack head is properly
engaged with the lift area closest to the wheel to be
changed.Do not raise the vehicle until you are sure the jack is
securely engaged.
4. Raise the vehicle by turning the jack screw to the right,
using the swivel wrench. Raise the vehicle only until the
tire just clears the surface and enough clearance is
obtained to install the spare tire. Minimum tire lift
provides maximum stability.
WARNING!
Raising the vehicle higher than necessary can make
the vehicle less stable. It could slip off the jack and
hurt someone near it. Raise the vehicle only enough
to remove the tire.
5. Remove the wheel nuts and pull the wheel and wheel
covers where applicable off the hub. Install the spare
wheel and wheel nuts with the cone shaped end of the
Jacking Locations

nuts toward the wheel. Lightly tighten the nuts. To avoid
the risk of forcing the vehicle off the jack, do not tighten
the nuts fully until the vehicle has been lowered.
WARNING!
To avoid possible personal injury, handle the wheel
covers with care to avoid contact with any sharp
edges.
NOTE:The wheel cover is held on the wheel by the
wheel nuts. When reinstalling original wheel, properly
align the wheel cover to the valve stem, place the wheel
cover onto the wheel, then install the wheel nuts.
6. Lower the vehicle by turning the jack screw to the left.
7. Finish tightening the nuts. Push down on the wrench
while tightening the wheel nuts. Alternate nuts until each
nut has been tightened twice. Correct wheel nut torque is100 ft. lbs (135 N´m). If you doubt that you have
tightened the nuts correctly, have them checked with a
torque wrench by your dealer or at a service station.
8. Remove the wheel blocks and lower the jack until it is
free. Stow the lug wrench, and jack in their designated
location. Secure all parts using the means provided.
WARNING!
A loose tire or jack thrown forward in a collision or
hard stop could endanger the occupants of the ve-
hicle. Always stow the jack parts and the spare tire in
the places provided.
9. Place the deflated (flat) tire in the cargo area,have the
tire repaired or replaced as soon as possible.

All Transaxles
CAUTION!
If the vehicle being towed requires steering, the
ignition switch must be in the ACCESSORY posi-
tion, not in the LOCK positions.
Do not attempt to use sling type equipment when
towing. When securing vehicle to flat bed truck, do
not attach to front or rear suspension components.
Damage to your vehicle may result from improper
towing.
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
transaxle remains in NEUTRAL.
Without The Ignition Key
Special care must be taken when the vehicle is towed
with the ignition in the LOCK position. A dolly should be
used under the front wheels if the rear wheels are raised.
Proper towing equipment is necessary to prevent dam-
age to the vehicle.
Towing This Vehicle Behind Another Vehicle (Flat
Towing With All Four Wheels On The Ground)
If your vehicle is equipped with a manual transaxle, it
may be towed at any legal highway speed, for any
distance, if the transaxle is in neutral.
If the ignition key is not available, vehicles with auto-
matic transaxles can not be flat towed at any time.

Inspect all hose connections such as clamps and cou-
plings to make sure they are secure and no leaks are
present.
Components should be replaced immediately if there is
any evidence of degradation that could cause failure.
Fuel System Connections
Electronic Fuel Injection high pressure fuel systems are
designed with tubes and special connects, connections
and clamps which have unique material characteristics to
provide adequate sealing and resist attack by deterio-
rated gasoline.
You are urged to use only the manufactures-specified
tubes, connections and clamps, or their equivalent in
material and specification, in any fuel system servicing.
Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically.
Suggested service intervals can be found in the Mainte-
nance Section.
WARNING!
Riding the brakes can lead to brake failure and
possibly an accident. Driving with your foot resting
or riding on the brake pedal can result in abnormally
high brake temperatures, excessive lining wear, and
possible brake damage. You wouldn't have your full
braking capacity in an emergency.
