engine DODGE CHALLENGER SRT 2011 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 or soft until after the
break-in period. This is a normal condition, and pre-
cision shifts will develop within a few shift cycles.
The shift lever is automatically locked while in the PARK
position. To move the shift lever out of the PARK
position, the brake pedal must be firmly pressed before
the shift lock will release.
Move the shift lever to the desired position only when the
engine is idling normally and the brake pedal is applied.
Do not release the brake pedal until ready to drive. The
vehicle may otherwise accelerate quickly when the shift
lever is in DRIVE or REVERSE 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 transmission into PARK, remove the key fob
from the ignition, and apply the parking brake. Once
the key fob 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 unattended children inside a
vehicle.

STARTING AND OPERATING 263

Over-Temperature Mode
The transmission electronics constantly monitor the
transmission oil temperature. If the transmission exceeds
normal operating temperature, the transmission will
change the way it shifts to help control the condition.
This may result in a slightly different feeling or response
during normal operation in DRIVE position. After the
transmission cools down, it will return to normal
operation.
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
prior to rotating the key fob to the LOCK position. The
key fob can only be removed from the ignition when the
ignition is in the LOCK position. Once the key fob is
removed, the shift lever is locked in PARK.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock (BTSI) system that holds the shift lever in the
PARK position when the ignition switch is in the LOCK
position (OFF position with Keyless Enter-N-Go). To
move the shift lever out of the PARK position, the
ignition switch must be turned to any other ignition
position (ACC, ON/RUN or START) whether the engine
is running or not, and the brake pedal must be pressed.
Five-Speed Automatic Transmission
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.
264 STARTING AND OPERATING

Gear Ranges
PARK
This range supplements the parking brake by locking the
transmission. The engine can be started in this range.
Never use PARK while the vehicle is in motion. Apply
the parking brake when leaving the 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, otherwise
the load on the transmission 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.Shift Lever
5
STARTING AND OPERATING 265

The following indicators should be used to ensure that
you have engaged the shift lever in 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 indicator display on the instrument
panel to ensure it is in the PARK position.
CAUTION!
Damage to the shift lever could result if the shift
lever is moved out of PARK before the ignition is
turned from the LOCK (OFF position with Keyless
Enter-N-Go) to ON position (RUN position with
Keyless Enter-N-Go).
REVERSE
This range is used for moving the vehicle rearward.
Always stop before moving the shift lever to REVERSE.
NEUTRAL
This range is used 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.
CAUTION!
Coasting the vehicle or driving for any other reason
with the shift lever in NEUTRAL can result in
transmission damage.
266 STARTING AND OPERATING

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.
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 fifth
gear. The DRIVE position provides optimum driving
characteristics under all normal operating conditions.
When frequent transmission shifting occurs when using
the DRIVE range, such as when operating the vehicleunder heavy loading conditions (in hilly terrain, travel-
ing into strong head winds, or while towing heavy
trailers), use the AutoStick
mode and select the “3”
range.
Delayed Shifts in Cold Temperatures
During cold temperature operation, you may notice
delayed upshifts depending on engine and transmission
temperature as well as vehicle speed. This feature im-
proves warm up time of the engine and transmission to
achieve maximum efficiency.
Temporary Transmission Limp Home Mode
The transmission is monitored for abnormal conditions.
If a condition is detected that could result in transmission
damage, the transmission will engage Limp Home Mode.
If vehicle acceleration worsens or the transmission no
longer shifts, the transmission is most likely operating in
the Limp Home Mode. In this mode, the transmission
will remain in the current gear until the vehicle is
5
STARTING AND OPERATING 267

brought to a stop. After the vehicle has stopped, PARK,
REVERSE, and NEUTRAL will continue to operate. Sec-
ond gear will operate in the DRIVE position. The Mal-
function Indicator Light (MIL) may be illuminated.
A reset feature is available to allow the vehicle to be
driven to an authorized dealer for service. To reset the
transmission, use the following procedure:
1. Stop the vehicle.
2. Move the shift lever to the PARK position.
3. Turn the ignition switch to the LOCK position (OFF
position with Keyless Enter-N-Go).
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Move the shift lever to the desired 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.
Have the transmission checked at your authorized dealer
as soon as possible.
If the problem has been momentary, the transmission can
be reset to regain all forward gears.
AUTOSTICK
AutoStick is a driver-interactive transmission 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 situations.
268 STARTING AND OPERATING

Operation
By placing the shift lever in 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 transmission range indicator.
NOTE:
•In AutoStickmode, the transmission will shift up and
down when the driver manually moves the shift lever
right (D+) or left (D-).
•An UPSHIFT message will appear in the Electronic
Vehicle Information Center (EVIC) portion of the in-
strument cluster when using AutoStick. This message
appears in order to alert the driver to upshift to the
next gear. The UPSHIFT message will display while
operating the vehicle at higher engine revolutions per
minute (RPM). You can shift in or out of the AutoStick
mode at any
time without taking your foot off the accelerator pedal.
When you wish to engage AutoStick, simply move the
shift lever to the right (D+) or left (D-) while in the DRIVE
position. The transmission will remain in the current gear
until an upshift or downshift is chosen. When you wish
to disengage AutoStick, hold the shift lever to the right
for at least two seconds. The transmission will now
operate automatically, shifting between the five available
gears.
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 or downshift at too high of a vehicle speed..
•The transmission will automatically downshift to 1st
gear when coming to a stop.
5
STARTING AND OPERATING 269

•Starting out in second gear is helpful in snowy or icy
conditions.
•Avoid using speed control when AutoStickis en-
gaged.
•The transmission will automatically shift up when
maximum engine speed is reached while AutoStick is
engaged.
•Transmission shifting will be more crisp/abrupt when
AutoStick is engaged.
DRIVING ON SLIPPERY SURFACES
Acceleration
Rapid acceleration on snow covered, wet, or other slip-
pery surfaces may cause the driving wheels to pull
erratically to the right or left. This phenomenon occurs
when there is a difference in the surface traction under
the rear (driving) wheels.
WARNING!
Rapid acceleration on slippery surfaces is dangerous.
Unequal traction can cause sudden pulling of the rear
wheels. You could lose control of the vehicle and
possibly have a collision. Accelerate slowly and
carefully whenever there is likely to be poor traction
(ice, snow, wet mud, loose sand, etc.).
Traction
When driving on wet or slushy roads, it is possible for a
wedge of water to build up between the tire and road
surface. This is known as hydroplaning and may cause
partial or complete loss of vehicle control and stopping
ability. To reduce this possibility, the following precau-
tions should be observed:
1. Slow down during rainstorms or when the roads are
slushy.
270 STARTING AND OPERATING

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.
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.

STARTING AND OPERATING 273

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.
CAUTION!
Do not use chemical flushes in your power steering
system as the chemicals can damage your power
steering components. Such damage is not covered by
the New Vehicle Limited Warranty.
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 “Maintaining Your Vehicle” for further
information.
