engine DODGE AVENGER 2009 2.G Service Manual

WARNING!
•It is dangerous to move the shift lever out of PARK
or NEUTRAL if the engine speed is higher than
idle speed. If your foot is not firmly on the brake
pedal, the vehicle could accelerate quickly forward
or in reverse. You could lose control of the vehicle
and hit someone or something. Only shift into
gear when the engine is idling normally and when
your right foot is firmly on the brake pedal.
(Continued)
WARNING! (Continued)
•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 PARK, remove the
key from the ignition, and apply the parking
brake. Once the key is removed from the ignition,
the shift lever is locked in the PARK position,
securing the vehicle against unwanted movement.
Furthermore, you should never leave children un-
attended inside a vehicle.
Brake/Transaxle Interlock System
This system prevents you from moving the shift lever out
of PARK and into any gear unless the brake pedal is
pressed. This system is active only while the ignition
switch is in the ON position.Always press the brake
pedal first, before moving the shift lever out of PARK.
STARTING AND OPERATING 271

NOTE:If a malfunction occurs, the transaxle will not
shift out of park. Battery power is required to release the
brake/transaxle interlock system. However, there is an
override system that allows you to shift out of PARK in
case of loss of power. To activate the override system:
•Firmly apply the parking brake
•Insert the ignition key and rotate it to the ON position
•Remove the cup holder liner
•Insert a key, screwdriver, or finger into the front hole
then push and hold the manual override release lever
forward.
•While holding the release lever forward, move the
shift lever from PARK to NEUTRAL. Release the
overrideNOTE:If this occurs, even if the override is successful,
it is recommended that you visit a dealer at your earliest
possible convenience. Your dealer has diagnostic equip-
ment to determine if the problem could recur.
Automatic Transaxle Ignition Interlock System
This system prevents the key from being removed unless
the shift lever is in PARK. It also prevents shifting out of
PARK unless the key is in the ON position and the brake
pedal is applied.
NOTE:If a malfunction occurs, the system will trap the
key in the ignition cylinder to warn you that this safety
feature is inoperable. The engine can be started and
stopped, but the key cannot be removed until you obtain
service.
272 STARTING AND OPERATING

4–Speed/6–Speed Automatic Transaxle — If
Equipped
The electronically controlled transaxle provides a precise
shift schedule. The transaxle electronics are self-
calibrating; therefore, the first few shifts on a new vehicle
may be somewhat abrupt. This is a normal condition, and
precision shifts will develop within a few hundred miles.
Gear Ranges
PARK
Supplement to the parking brake by locking the trans-
axle. The engine can be started in this range. Never
attempt to use PARK while vehicle is in motion. Apply
parking brake when leaving vehicle in this range.
When parking on a flat surface, place the shift lever in the
PARK position first, and then apply the parking brake.
When parking on a hill, it is important to set the parking
brake before placing the shift lever in PARK, otherwisethe load on the transaxle locking mechanism may make it
difficult to move the shift lever out of PARK. As an added
precaution, turn the front wheels toward the curb on a
downhill grade and away from the curb on an uphill
grade.
WARNING!
Never use the PARK position as a substitute for the
parking brake. Always apply the parking brake fully
when parked to guard against vehicle movement and
possible injury or damage.
CAUTION!
DO NOT race the engine when shifting from PARK
or NEUTRAL positions into another gear range as
this can damage the drivetrain.
STARTING AND OPERATING 273
5

REVERSE
Use this range for moving the vehicle rearward. Shift into
this range only after the vehicle has come to a complete
stop.
NEUTRAL
Engine may be started in this range.
WARNING!
Do not coast in NEUTRAL and never turn off the
ignition to coast down a hill. These are unsafe
practices that limit your response to changing traffic
or road conditions. You might lose control of the
vehicle and have an accident.
DRIVE — 6 Speed Transaxle
This range should be used for most city and highway
driving. It provides the smoothest upshifts, downshifts,
and best fuel economy. However, use the AutoStickmode and select the appropriate gear when frequent
transaxle shifting occurs in the DRIVE range. For ex-
ample: When operating the vehicle under heavy loading
conditions, (i.e. in hilly terrain, traveling into strong
headwinds, or while towing heavy trailers). Under these
conditions, reducing shifting by selecting the appropriate
gear in AutoStickwill improve the performance and
extend transmission life by reducing excessive shifting
and heat build-up.
DRIVE— 4 Speed Transaxle
This range should be used for most city and highway
driving, it provides the smoothest upshifts, downshifts,
and best fuel economy. However, select the3range
when frequent transaxle shifting occurs while using the
DRIVE range, such as when operating the vehicle under
heavy loading conditions, (i.e. in hilly terrain, traveling
into strong headwinds, or while towing heavy trailers).
274 STARTING AND OPERATING

Under these conditions, using the3range will improve
performance and extend transaxle life by reducing exces-
sive shifting and heat build-up.
DRIVE 3— 4 Speed Transaxle
This range eliminates shifts into 4th gear. The transaxle
will operate normally in First and Second. Shifts into
Third may be delayed to provide second gear operation
at higher speeds. The3range should also be used when
descending steep grades to prevent brake system dis-
tress.
NOTE:Using the3range while operating the vehicle
under heavy operating conditions will improve perfor-
mance and extend transaxle life by reducing excessive
shifting and heat build-up.
LOW — 4 Speed Transaxle
This range should be used for engine braking when
descending very steep grades. In this range, upshifts willoccur only to prevent engine overspeed while downshifts
occur earlier than other gear range selections.
CAUTION!
If the transaxle operating temperature exceeds ac-
ceptable limits, the vehicle computer will override
OVERDRIVE and “3” DRIVE range by changing
shift points. This is done to prevent transaxle damage
due to overheating.
Reset Mode - Electronic Transaxle
The transaxle is monitored electronically for abnormal
conditions. If a condition is detected that could cause
damage, the transaxle automatically shifts into second
gear. The transaxle remains in second gear (3rd gear with
a six speed automatic) despite the forward gear selected.
PARK, REVERSE, and NEUTRAL will continue to oper-
ate. This Reset feature allows the vehicle to be driven to
a dealer for service without damaging the transaxle.
STARTING AND OPERATING 275

In the event that the problem has been momentary, the
transaxle can be reset to regain all forward gears.
1. Stop the vehicle.
2. Shift into PARK.
3. Turn the ignition OFF, and then restart the engine.
4. Shift into the desired gear range 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.AUTOSTICK— IF EQUIPPED
AutoStickis a driver-interactive transaxle that offers six
manual ratio changes to provide you with more control.
AutoStickallows you to maximize engine braking,
eliminate undesirable upshifts and downshifts, and im-
prove overall vehicle performance. This system can also
provide you with more control during passing, city
driving, cold slippery conditions, mountain driving,
trailer towing, and many other situations.
Operation
By placing the shift lever one shift-level below the DRIVE
position, it can be moved from side to side. This allows
the driver to select a higher or lower range of gears.
Moving the shift lever to the Left (-) triggers a downshift
and to the Right (+) an upshift. The gear position will
display in the instrument cluster on the transaxle range
indicator.
276 STARTING AND OPERATING

NOTE:In Autostickmode, the transaxle will only shift
up or down when the driver moves the shift lever to the
Right (+) or Left (-).
AutoStickis deactivated when the shift lever is shifted
from the AutoStick (+/-) position into the DRIVE
position.
General Information
•
You can start out in first or second gear. The system
will ignore attempts to upshift at too low of a vehicle
speed.
•If a ratio other than 1st is selected, and the vehicle is
brought to a stop, the transaxle control logic will
automatically select the 1st gear ratio.
•Starting out in second gear is helpful in snowy or icy
conditions.
•Avoid using speed control when Autostickis en-
gaged.
•The transaxle will automatically shift up when maxi-
mum engine speed is reached while Autostickis
engaged.
•Transaxle shifting will be more noticeable when
Autostickis engaged.
•If a downshift would cause the engine to over-speed,
that shift will not occur until it is safe for the engine.
Mostly the transaxle will stay in the manually selected
ratio, however.
•If the system detects powertrain overheating, the
transaxle 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
AutoStickmode and the transaxle will return to the
automatic mode until the problem is corrected.

CAUTION! (Continued)
•Driving through standing water may cause dam-
age to your vehicle’s drivetrain components. Al-
ways inspect your vehicle’s fluids (i.e., engine oil,
transmission/transaxle, axle, etc.) for signs of con-
tamination (i.e., fluid that is milky or foamy in
appearance) after driving through standing water.
Do not continue to operate the vehicle if any fluid
appears contaminated, as this may result in further
damage. Such damage is not covered by the New
Vehicle Limited Warranty.
•Getting water inside your vehicle’s engine can
cause it to lock up and stall out, and cause serious
internal damage to the engine. Such damage is not
covered by the New Vehicle Limited Warranty.
WARNING!
•Driving through standing water limits your vehi-
cle’s traction capabilities. Do not exceed 5 mph
(8 km/h) when driving through standing water.
•Driving through standing water limits your vehi-
cle’s braking capabilities, which increases stop-
ping distances. Therefore, after driving through
standing water, drive slowly and lightly press on
the brake pedal several times to dry the brakes.
•Getting water inside your vehicle’s engine can
cause it to lock up and stall out, and leave you
stranded.
•Failure to follow these warnings may result in
injuries that are serious or fatal to you, your
passengers, and others around you.
280 STARTING AND OPERATING

Power Steering Fluid Check
Checking the power steering fluid level at a defined
service interval is not required. The fluid should only be
checked if a leak is suspected, abnormal noises are
apparent, and/or the system is not functioning as antici-
pated. Coordinate inspection efforts through an autho-
rized dealer.
No chemical flushes should be used in any power
steering system; only the approved lubricant may be
used.
WARNING!
Fluid level should be checked on a level surface and
with the engine off to prevent injury from moving
parts and to ensure accurate fluid level reading. Do
not overfill. Use only manufacturer’s recommended
power steering fluid.If necessary, add fluid to restore to the proper indicated
level. With a clean cloth, wipe any spilled fluid from all
surfaces. Refer to “Fluids, Lubricants, and Genuine
Parts” in Section 7 for the correct fluid type.
PARKING BRAKE
The parking brake should always be applied when the
driver is not in the vehicle.
WARNING!
Never use the PARK position as a substitute for the
parking brake. Always apply parking brake fully
when parked to guard against vehicle movement and
possible injury or damage.
When parking on a flat surface, place the shift lever in the
PARK position first, and then apply the parking brake.
282 STARTING AND OPERATING

•If the parking brake is applied while the vehicle is
moving, a chime will sound to alert the driver. The
chime will sound up to 10 times or until the vehicle
has returned to a stop.
The Brake System Warning Light in the instrument
cluster will turn on when the parking brake is applied
and the ignition switch is on.
NOTE:This light only shows that the parking brake is
applied. It does not show the degree of brake application.
CAUTION!
If the Brake System Warning Light remains on with
the parking brake released, a brake system malfunc-
tion is indicated. Have the brake system serviced by
an authorized dealer immediately.
WARNING!
•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. Do not leave the key in
the ignition. A child could operate power win-
dows, other controls, or move the vehicle.
•Be sure the parking brake is fully disengaged
before driving: failure to do so can lead to brake
failure, and an accident.
BRAKE SYSTEM
Your vehicle is equipped with power assisted brakes as
standard equipment. In the event power assist is lost for
any reason (i.e., repeated brake applications with the
engine off) the brakes will still function. However, the
effort required to brake the vehicle will be much greater
than that required with the power system operating.
