engine DODGE CHALLENGER SRT 2012 3.G Workshop Manual

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 console mounted shift lever provides PARK, RE-
VERSE, NEUTRAL, DRIVE, and AutoStickshift posi-
tions. Once the shifter is in DRIVE, tapping the shift lever
side to side (+/-), or pressing the paddle shifters will
place the vehicle in AutoStick. AutoStick allows for
manual shift control (refer to “AutoStick ” in this sec-
tion). While in AutoStick the transmission gear position
will be displayed in the EVIC.Gear Ranges
DO NOT race the engine when shifting from PARK or
NEUTRAL into another gear range.
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 the vehicle is in
motion. Apply the parking brake when leaving the
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.
270 STARTING AND OPERATING

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)

STARTING AND OPERATING 271

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)
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 num-
ber 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.
272 STARTING AND OPERATING

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 to the left until it stops and is fully
seated.
•Look at the shift lever position display and verify that
it indicates the PARK position.
•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 engine running. The engine may be started
in this range. Set the parking brake and shift the trans-
mission 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.

may be illuminated. 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.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
Steering Wheel Mounted Paddle Shifters Or
Console Mounted Shifter
AutoStickis 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, and improve overall vehicle perfor-
mance.
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 press one of the steering wheel mounted shift paddles (+/-). When AutoStick
is active,
the current transmission gear is displayed in the Elec-
tronic Vehicle Information Center (EVIC) portion of the
instrument cluster. In AutoStick mode, the transmission
will shift when manually selected by the driver (using the
shift lever, or the shift paddles), 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.
•The transmission will automatically downshift as the
vehicle slows (to prevent engine lugging) and will
display the current gear.
•The transmission will automatically downshift to first
gear when coming to a stop.
•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.
276 STARTING AND OPERATING

•The system will ignore attempts to upshift at too low
of a vehicle speed.
•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 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.
•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.
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.
Auto
•
If AutoStick is engaged while in “Auto” mode, the
transmission will automatically shift up if maximum
engine speed is reached.
•Heavily pressing the accelerator pedal may generate
an automatic downshift for improved acceleration.
•This mode should be used for most driving situations.

STARTING AND OPERATING 277

Sport
•
If AutoStick is engaged while in “Sport” mode, the
transmission will remain in the selected gear even
when maximum engine speed is reached. Refer to
“Sport Mode” in “Starting And Operating” for further
information.
•Engine overspeed protection is achieved through fuel
cut off at or near redline.
•This mode will provide aggressive shifting and is
intended for spirited driving.
SPORT MODE
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 whenpressed will cycle through three different driving modes.
This is the description of each mode of operation:
•Off – This is the initial position. This mode will give a
sporty, but comfortable ride. Within this mode, the
suspension will adapt to the vehicle inputs, including
SPORT Button
278 STARTING AND OPERATING

Shallow Standing Water
Although your vehicle is capable of driving through
shallow standing water, consider the following Caution
and Warning before doing so.
CAUTION!
•Always check the depth of the standing water
before driving through it. Never drive through
standing water that is deeper than the bottom of
the tire rims mounted on the vehicle.
•Determine the condition of the road or the path
that is under water, and if there are any obstacles
in the way, before driving through the standing
water.
•Do not exceed 5 mph (8 km/h) when driving
through standing water. This will minimize wave
effects.
CAUTION!
•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, axle, etc.) for signs of contamination
(i.e., fluid that is milky or foamy in appearance)
after driving through standing water. Do not con-
tinue to operate the vehicle if any fluid appears
contaminated, as this may result in further dam-
age. 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.
282 STARTING AND OPERATING

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.
POWER STEERING
The standard power steering system will give you good
vehicle response and increased ease of maneuverability
in tight spaces. The system will provide mechanical
steering capability if power assist is lost.
If for some reason the power assist is interrupted, it will
still be possible to steer your vehicle. Under these condi-
tions, you will observe a substantial increase in steering
effort, especially at very low vehicle speeds and during
parking maneuvers.
NOTE:
•Increased noise levels at the end of the steering wheel
travel are considered normal and do not indicate that
there is a problem with the power steering system.
•Upon initial start-up in cold weather, the power steer-
ing pump may make noise for a short amount of time.
This is due to the cold, thick fluid in the steering
system. This noise should be considered normal, and it
does not in any way damage the steering system.
