engine DODGE CHALLENGER 2009 3.G Service Manual

WARNING!
Do not attempt to push or tow your vehicle to get it
started. Unburned fuel could enter the catalytic con-
verter and once the engine has started, ignite and
damage the converter and vehicle. If the vehicle has
a discharged battery, booster cables may be used to
obtain a start from another vehicle. This type of start
can be dangerous if done improperly, so follow the
procedure carefully. See Section 6 of this manual for
jump-starting instructions.
Automatic Transmission — If Equipped
The shift lever must be in the NEUTRAL or PARK
position before you can start the engine. Apply the brakes
before shifting into any driving gear.
CAUTION!
Damage to the transmission may occur if the follow-
ing precautions are not observed:
•Shift into PARK only after the vehicle has come to
a complete stop.
•Shift into or out of REVERSE only after the
vehicle has come to a complete stop and the engine
is at idle speed.
•Do not shift from REVERSE, PARK, or NEUTRAL
into any forward gear when the engine is above
idle speed.
•Before shifting into any gear, make sure your foot
is firmly on the brake pedal.

248 STARTING AND OPERATING

If Engine Fails To Start
WARNING!
•Never pour fuel or other flammable liquids into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in a flash fire causing
serious personal injury.
•Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
mission cannot be started this way. Unburned fuel
could enter the catalytic converter and once the
engine has started, ignite and damage the converter
and vehicle. If the vehicle has a discharged battery,
booster cables may be used to obtain a start from a
booster battery or the battery in another vehicle. This
type of start can be dangerous if done improperly.
Refer to Section 6 for proper jump-starting proce-
dures and follow them carefully.

CAUTION!
To prevent damage to the starter, wait 10 to 15 sec-
onds before trying again.
After Starting
The idle speed is controlled automatically and it will
decrease as the engine warms up.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine, and permits
quicker starts in cold weather. Connect the cord to a
standard 110-115 Volt AC electrical outlet with a
grounded, three-wire extension cord.
The engine block heater cord is routed under the hood on
the driver side of the vehicle. It has a removable cap that
is located on the driver side of the Integrated Power
Module.
250 STARTING AND OPERATING

Recommended Shift Speeds
To utilize your manual transmission efficiently for fuel
economy, it should be upshifted as listed in recom-
mended shift speed chart.
MANUAL TRANSMISSION
RECOMMENDED SHIFT SPEEDS
Axle
Ratio1-4 4-5 5-6
3.73mph 20 25 42
(km/h) (32) (40) (67)
3.91mph 20 37 48
(km/h) (32) (59) (77)
Earlier upshifts during cruise conditions (relatively
steady speeds) may result in increased fuel economy.
Higher upshift speeds may be used to obtain a desired
acceleration rate.NOTE:
•Your vehicle is equipped with a transmission reverse
inhibitor system. When vehicle speed is greater than
3 mph (5 km/h), the reverse inhibitor activates to help
prevent shifts into REVERSE. When at a complete
stop, you may notice lighter shift efforts into REVERSE
with the ignition key ON, as compared to the ignition
key OFF position. This is normal operation of the
transmission reverse inhibitor system.
•Due to the high performance nature of your drivetrain,
you may hear your transmission. This can be most
noticeable when the vehicle is idling in NEUTRAL
with the clutch engaged (clutch pedal released), but it
may also be heard when driving at low engine RPM.
Also, this may be more noticeable when the transmis-
sion is warm. This is a normal condition and is not an
indication of a problem with your clutch or
transmission.5
STARTING AND OPERATING 253

1–4 Skip Shift
There are times when you must shift the transmission
directly from first gear to fourth gear instead of from first
gear to second gear. This is to help you get the best
possible fuel economy from your vehicle. This occurs
when the engine coolant (antifreeze) is higher than 106°F
(41°C), vehicle speed is greater than 19 mph (30 km/h)
but less than 21 mph (34 km/h), and the transmission is
in first gear, and the accelerator is at 1/4 throttle or less.
The 1–4 Skip Shift indicator message will be displayed
during these times.
When the 1–4 Skip Shift indicator message is displayed,
the shift mechanism will only allow shifts from first gear
to fourth gear. After you shift the transmission to fourth
gear, you can press the clutch in and shift to another
forward gear.
Downshifting
To maintain a safe speed and prolong brake life, down-
shift to maintain a safe speed when descending a steep
grade.
WARNING!
Skipping more than one gear while downshifting,
could cause you to lose control of your vehicle. You
could have an accident.
CAUTION!
•If you skip more than one gear while downshift-
ing or downshift at too high an engine speed, you
could damage the engine, transmission, or clutch.
•Do not downshift into first gear when the vehicle
is moving faster than 15 mph (24 km/h), as you
could damage the engine and/or clutch.
254 STARTING AND OPERATING

AUTOMATIC TRANSMISSION — IF EQUIPPED
CAUTION!
Damage to the automatic transmission may occur if
the following precautions are not observed:
•Shift into PARK only after the vehicle has come to
a complete stop.
•Shift into or out of REVERSE only after the
vehicle has come to a complete stop and the engine
is at idle speed.
•Do not shift from REVERSE, PARK, or NEUTRAL
into any forward gear when the engine is above
idle speed.
•Before shifting into any gear, make sure your foot
is firmly on the brake pedal.
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.
General Information
The automatic transmission selects individual gears au-
tomatically, dependent upon:
•Altitude
•Vehicle loading
•Driving style
