engine DODGE CHALLENGER 2012 3.G Workshop Manual

WARNING! (Continued)
•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 pressing on
the brake pedal, the vehicle could accelerate
quickly forward or in reverse. You could lose
control of the vehicle and hit someone or some-
thing. Only shift into gear when the engine is
idling normally and when your foot is firmly
pressing on the brake pedal.
Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition Park Inter-
lock which requires the shift lever to be placed in PARK
before the engine can be turned off. This helps the driver
avoid inadvertently leaving the vehicle without placing
the transmission in PARK. This system also locks the shift
lever in PARK whenever the ignition switch is in the OFF
position.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock (BTSI) that holds the shift lever in the PARK
position unless the brakes are applied. To move the shift
lever out of the PARK position, the ignition switch must
be turned to the ON/RUN or START position (engine
running or not) and the brake pedal must be pressed.
Five-Speed Automatic Transmission
The shift lever position display (located in the instrument
panel cluster) indicates the transmission gear range. You
must press the brake pedal to move the shift lever out of
the PARK position (refer to “Brake/Transmission Shift
Interlock System” in this section). To drive, move the shift
lever from PARK or NEUTRAL to the DRIVE position.
266 STARTING AND OPERATING

The electronically-controlled transmission provides a
precise shift schedule. The transmission 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 (kilometers).
Shifting from DRIVE to PARK or REVERSE should be
done only after the accelerator pedal is released and the
vehicle is stopped. Be sure to keep your foot on the brake
pedal when moving the shift lever between these gears.
The transmission shift lever has only PARK, REVERSE,
NEUTRAL, and DRIVE shift positions. Manual down-
shifts can be made using the “AutoStick” shift control
(refer to “AutoStick” in this section). Moving the shift
lever to the left or right (-/+) while in the DRIVE position
will manually select the transmission gear, and will
display that gear in the instrument cluster as 4, 3, 2, 1.
Gear Ranges
DO NOT race the engine when shifting from PARK or
NEUTRAL into another gear range.
Shift Lever
5
STARTING AND OPERATING 267

PARK
This range supplements the parking brake by locking the
transmission. The engine can be started in this range.
Never attempt to use PARK while vehicle is in motion.
Apply the parking brake when leaving vehicle in this
range.
When parking on a level surface, you may place the shift
lever in the PARK position first, and then apply the
parking brake.
When parking on a hill, apply the parking brake before
placing the shift lever in PARK, otherwise the load on the
transmission locking mechanism may make it difficult to
move the shift lever out of PARK. As an added precau-
tion, 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.
•Your vehicle could move and injure you and others
if it is not completely in PARK. Check by trying to
move the shift lever rearward (with the brake
pedal released), after you have placed it in PARK.
Make sure the transmission is in PARK before
leaving the vehicle.(Continued)

WARNING! (Continued)
•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 pressing on
the brake pedal, the vehicle could accelerate
quickly forward or in reverse. You could lose
control of the vehicle and hit someone or some-
thing. Only shift into gear when the engine is
idling normally and when your foot is firmly
pressing on the brake pedal.(Continued)
WARNING! (Continued)
•Unintended movement of a vehicle could injure
those in or near the vehicle. As with all vehicles,
you should never exit a vehicle while the engine is
running. Before exiting a vehicle, always apply the
parking brake, shift the transmission into PARK,
and turn the engine off. When the ignition is in the
OFF position, the shift lever is locked in the
PARK, securing the vehicle against unwanted
movement.
•When leaving the vehicle, always remove the key
fob from the ignition and lock your vehicle.(Continued)

STARTING AND OPERATING 269

WARNING! (Continued)
•Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children
to be in a vehicle unattended is dangerous for a
number of reasons. A child or others could be
seriously or fatally injured. Children should be
warned not to touch the parking brake, brake
pedal or the shift lever.
•Do not leave the key fob in or near the vehicle, and
do not leave Keyless Enter-N-Go in the ACC or
ON/RUN mode. A child could operate power win-
dows, other controls, or move the vehicle.
CAUTION!
•Before moving the shift lever out of PARK, you
must turn the ignition switch from the LOCK/OFF
position to the ON/RUN position, and also press
the brake pedal. Otherwise, damage to the shift
lever could result.
•DO NOT race the engine when shifting from
PARK or NEUTRAL into another gear range, as
this can damage the drivetrain.
The following indicators should be used to ensure that
you have engaged the shift lever into the PARK position:
•When shifting into PARK, move the shift lever all the
way forward and left until it stops and is fully seated.
•Look at the shift lever position display and verify that
it indicates the PARK position.
270 STARTING AND OPERATING

•With brake pedal released, verify that the shift lever
will not move out of PARK.
REVERSE
This range is for moving the vehicle backward. Shift into
REVERSE only after the vehicle has come to a complete
stop.
NEUTRAL
Use this range when the vehicle is standing for prolonged
periods with the engine running. The engine may be
started in this range. Set the parking brake and shift the
transmission into PARK if you must leave the vehicle.
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 a collision.
CAUTION!
Towing the vehicle, coasting, or driving for any other
reason with the transmission in NEUTRAL can result
in severe transmission damage. Refer to “Recre-
ational Towing” in “Starting And Operating” and
“Towing A Disabled Vehicle” in “What To Do In
Emergencies” for further information.
DRIVE
This range should be used for most city and highway
driving. It provides the smoothest upshifts and down-
shifts, and the best fuel economy. The transmission
automatically upshifts through underdrive first, second,
and third gears, direct fourth gear and overdrive fifth
gear. The DRIVE position provides optimum driving
characteristics under all normal operating conditions.
5
STARTING AND OPERATING 271

When frequent transmission shifting occurs (such as
when operating the vehicle under heavy loading condi-
tions, in hilly terrain, traveling into strong head winds, or
while towing heavy trailers), use the “AutoStick” mode
(refer to “AutoStick” in this section) to select a lower
gear. Under these conditions, using a lower gear will
improve performance and extend transmission life by
reducing excessive shifting and heat buildup.
Transmission Limp Home Mode
Transmission function is monitored electronically for
abnormal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
Mode is activated. In this mode, the transmission remains
in the current gear until the vehicle is brought to a stop.
After the vehicle has stopped, the transmission will
remain in second gear regardless of which forward gear is selected. PARK, REVERSE, and NEUTRAL will con-
tinue to operate. Limp Home Mode allows the vehicle to
be driven to an authorized dealer for service without
damaging the transmission.
In the event of a momentary problem, the transmission
can be reset to regain all forward gears by performing the
following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK.
3. Turn the engine OFF.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no
longer detected, the transmission will return to normal
operation.
272 STARTING AND OPERATING

NOTE:Even if the transmission can be reset, we recom-
mend that you visit your authorized dealer at your
earliest possible convenience. Your authorized dealer has
diagnostic equipment to determine if the problem could
recur.
If the transmission cannot be reset, authorized dealer
service is required.
Overdrive Operation
The automatic transmission includes an electronically
controlled Overdrive (fifth gear). The transmission will
automatically shift into the Overdrive gear if the follow-
ing conditions are present:
•the shift lever is in the DRIVE position,
•vehicle speed is sufficiently high, and
•the driver is not heavily pressing the accelerator.
AUTOSTICK
AutoStick is a driver-interactive transmission feature
that offers manual gear shifting to provide you with more
control of the vehicle. AutoStick allows you to maximize
engine braking, eliminate undesirable upshifts and
downshifts, and improve 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 situa-
tions.
Operation
When the shift lever is in the DRIVE position, the
transmission will operate automatically, shifting between
the five available gears. To engage AutoStick, simply
move the shift lever to the right or left (+/-) while in the
DRIVE position, or tap one of the steering wheel-
mounted shift paddles (+/-), if equipped. When
AutoStick is active, the current transmission gear is
displayed in the instrument cluster. In AutoStick mode,
5
STARTING AND OPERATING 273

the transmission will shift up or down when (+/-) is
manually selected by the driver (using the shift lever, or
the shift paddles [if equipped]), unless an engine lugging
or overspeed condition would result. It will remain in the
selected gear until another upshift or downshift is cho-
sen, except as described below.
•An “UPSHIFT” message will appear in the Electronic
Vehicle Information Center (EVIC) portion of the in-
strument cluster when using AutoStick, to alert the
driver to upshift to the next gear. The “UPSHIFT”
message will appear when approaching the maximum
engine speed.
•If AutoStick is engaged while in DRIVE mode, the
transmission will automatically shift up when maxi-
mum engine speed is reached.
•If AutoStick is engaged while in SPORT mode, the
transmission will remain in the selected gear even when maximum engine speed is reached. The trans-
mission will upshift only when commanded by the
driver.
•The transmission will automatically downshift as the
vehicle slows down (to prevent engine lugging) and
will display the current gear.
•The transmission will automatically downshift to first
gear when coming to a stop. After a stop, the driver
should manually upshift (+) the transmission as the
vehicle is accelerated.
•You can start out in first or second gear. Tapping (+) (at
a stop) will allow starting in second gear. Starting out
in second gear is helpful in snowy or icy conditions.
•The system will ignore attempts to upshift at too low
of a vehicle speed.
•Avoid using speed control when AutoStick
is en-
gaged.
274 STARTING AND OPERATING

•Transmission shifting will be more noticeable when
AutoStickis engaged.
To disengage AutoStick mode, hold the shift lever to the
right or press and hold the (+) shift paddle (if equipped)
until “D” is once again displayed in the instrument
cluster. You can shift in or out of the AutoStick mode at
any time without taking your foot off the accelerator
pedal.
WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their
grip and the vehicle could skid, causing a collision or
personal injury.
SPORT MODE — IF EQUIPPED
This vehicle is equipped with an electronic controlled
dampening system. This system reduces body roll and pitch in many driving situations including cornering,
acceleration and braking. In addition, the driver has the
ability to select a more aggressive shifting pattern. On the
center console, there is a “SPORT” button that when
pressed will cycle through three different driving modes.
This is the description of each mode of operation:SPORT Button
