engine DODGE CHARGER 2010 7.G Service Manual

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.
WARNING!
Remember to disconnect the cord before driving.
Damage to the 110-115 Volt electrical cord could cause
electrocution.
AUTOMATIC TRANSMISSION
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.
266 STARTING AND OPERATING

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
•Shift lever position
•Accelerator position
•Vehicle speed
The gear shifting process is continuously adapted, de-
pendent on the driving style, the driving situation, and
the road characteristics.
NOTE:
•After selecting any driving position, wait a moment to
allow the gear to engage fully before accelerating,
especially when the engine is cold.
•If there is a need to restart the engine, be sure to turn
the ignition switch to the LOCK position before re-
starting. Transmission engagement may be delayed up
to 10 seconds after restart if the ignition switch is not
turned to the LOCK position first.

STARTING AND OPERATING 267

•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 the 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 switch, and apply the parking
brake. Once the key fob is removed from the ignition
switch, 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.
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.
268 STARTING AND OPERATING

This may result in a slightly different feeling or response
during normal operation in the 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 turning the ignition switch to the LOCK position.
The key fob can only be removed from the ignition switch
when the ignition switch is in the LOCK position and
once removed the shift lever is locked in PARK.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock System (BTSI) that holds the shift lever in the
PARK position when the ignition switch is in the LOCK
position. To move the shift lever out of the PARKposition, the ignition switch must be turned to either the
ON or START position (engine running or not) and the
brake pedal must be pressed.
Brake/Transmission Interlock Manual Override
There is an override for the BTSI that allows you to move
the shift lever out of the PARK position if an electrical
system malfunction occurs (i.e., dead battery). To access
the override, remove the rubber tray from the storage bin
located to the right of the shift lever. The override access
port is at the top of the bin to the right of the shift lever
gate.
1. Turn the ignition switch to the ACC or ON position
without starting the engine.
2. Firmly set the parking brake.
3. Press and maintain firm pressure on the brake pedal.

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 271

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 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.
REVERSE
This range is used for moving the vehicle rearward.
Always stop before moving the shift lever to REVERSE.
CAUTION!
Damage to the shifter could result if the shift lever is
moved out of PARK before the ignition switch is
turned from the LOCK to the ON position.
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 if you
must leave the vehicle.
CAUTION!
Coasting the vehicle or driving for any other reason
with shift lever in NEUTRAL can result in transmis-
sion damage.
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.
272 STARTING AND OPERATING

“D” (Overdrive)
This range is used for most city and highway driving. It
provides the smoothest up shifts and down shifts and the
best fuel economy. Select the “3” range when frequent
transmission shifting occurs when using the Overdrive
range, such as when operating the vehicle under heavy
loading conditions (in hilly terrain, traveling into strong
head winds, or while towing heavy trailers).
NOTE:
•If the vehicle is started in cold temperatures, shifts into
Overdrive may be delayed. Normal Overdrive and
shifting operation will resume when the temperature
of the transmission reaches the appropriate tempera-
ture. Refer to the “Note” under “Torque Converter
Clutch” later in this section.
•If the transmission temperature gets too hot, the
transmission may downshift out of Overdrive or en-
gage Overdrive at higher vehicle speeds until the
transmission cools down. After cooldown, Overdrive
will resume normal operation.
“3” (Third)
This range eliminates shifts into Overdrive. The transmis-
sion will operate normally in 1st, 2nd, and 3rd while in
this range. The “3” position should also be used when
descending steep grades to prevent brake system dis-
tress.
NOTE:Using the “3” range while operating the vehicle
under heavy operating conditions will improve perfor-
mance and extend transmission life by reducing exces-
sive shifting and heat buildup.
“L” (Low)
This range should be used for engine braking when
descending very steep grades. In this range, upshifts will
5
STARTING AND OPERATING 273

occur only to prevent engine overspeed while downshifts
occur earlier than in other gear range selections.
CAUTION!
Never race the engine with the brakes on and the
vehicle in gear, and never hold the vehicle on an
incline without applying the brakes. These practices
can cause overheating and damage to the transmis-
sion.
Torque Converter Clutch
A feature designed to improve fuel economy has been
added to the automatic transmission in this vehicle. A
clutch within the torque converter engages automatically
at calibrated speeds. This may result in a slightly differ-
ent feeling or response during normal operation in high
gear. When the vehicle speed drops or during accelera-
tion, the clutch automatically and smoothly disengages.NOTE:
•The torque converter clutch will not engage until the
transmission fluid and engine coolant is warm (usu-
ally after 1–3 miles [1.6–4.8 km] of driving). Because
engine speed is higher when the torque converter
clutch is not engaged, it may seem as if the transmis-
sion is not shifting into Overdrive when cold. This is
considered a normal condition. Pulling the shift lever
into the “3” position will show that the transmission is
able to shift into and out of Overdrive.
•If the vehicle has not been driven for several days, the
first few seconds of operation after shifting the trans-
mission into gear may seem sluggish. This is due to the
transmission fluid partially draining from the torque
converter into the transmission. This is considered a
normal condition and it will not cause damage to the
transmission. The torque converter will refill within
five seconds of shifting from PARK into any other gear
position.
274 STARTING AND OPERATING

Transmission Limp Home Mode
The transmission is monitored for abnormal conditions.
If a condition is detected that could cause damage, the
transmission automatically shifts into second gear. The
transmission remains in second gear despite the forward
gear selected. PARK, REVERSE, and NEUTRAL will
continue to operate. This reset feature allows the vehicle
to be driven to an authorized dealer for service without
damaging the transmission.
If the problem has been momentary, the transmission can
be reset to regain all forward gears.
•Stop the vehicle and shift into PARK.
•Turn the ignition switch to the LOCK position, then
start the engine.
•Shift into DRIVE and resume driving.
NOTE: Even if the transmission can be reset, we recom-
mend that you visit an authorized dealer at your earliest
possible convenience.
If the transmission cannot be reset, authorized dealer
service is required.

STARTING AND OPERATING 275

Five-Speed Automatic Transmission – If
Equipped
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.
