engine CHRYSLER 300 SRT 2008 1.G Service 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 depressed 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
from the ignition, and apply the parking brake. Once
the key is removed from the ignition, the transmis-
sion 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 303

To activate the override, first insert the key into the
ignition switch and turn it to the ACC or ON position.
Then, press the pink-colored tab trough the access pot
with a small flat blade screwdriver or alike. While
pressing the override, move the shift lever out of the
PARK position. When complete, return the rubber tray to
its original position.
5-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.
Gear Ranges
PARK
PARK 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.

REVERSE
Shift into REVERSE gear only when the vehicle is com-
pletely stopped.
NEUTRAL
In NEUTRAL, no power is transmitted from the engine to
the drive axle. When the brakes are released, the vehicle
can be moved freely (pushed or towed). Do not engage
NEUTRAL position while driving except to coast when
the vehicle is in danger of skidding (e.g., on icy roads).
The engine may be started in this range. Use this range
for starting your vehicle if it is moving or being towed.
CAUTION!
Coasting the vehicle or driving for any other reason
with the shift lever in NEUTRAL can result in
transmission 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.
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 5th
gear. The DRIVE position provides optimum driving
characteristics under all normal operating conditions.
STARTING AND OPERATING 307
5

When frequent transmission shifting occurs when using
the Overdrive range, such as when operating the vehicle
under heavy loading conditions (in hilly terrain, travel-
ing into strong head winds, or while towing heavy
trailers, use the AutoStickmode and select the “3”
range.
AutoStickGear Selection
The AutoStickfeature can be selected by pressing the
shift lever to the right or the left with the lever in the
DRIVE position. The gear currently selected is indicated
in the instrument cluster display. Briefly, press the shift
lever in the “D -” direction and the transmission will shift
from the current gear to the next lower gear.
Press and hold the shift lever in the “D-” direction and
the transmission will shift from the current gear directly
to the next lowest gear for best acceleration.
NOTE:To avoid overrevving the engine when the shift
lever is moved in “D -” direction, the transmission willnot shift to a lower gear if the engine’s revolutions per
minute (RPM) limit would be exceeded.
Briefly press the shift lever in the “D +” direction and the
transmission will shift from the current gear to the next
higher gear.
Press and hold the shift lever in the “D +” direction and
the transmission will shift from the current gear directly
to gear “D.”
WARNING!
On slippery road surfaces never downshift in order
to obtain braking action. This could result in drive
wheel slip and reduced vehicle control. Your vehi-
cle’s ABS will not prevent this type of loss of control.
You could lose control of your vehicle and have an
accident.
308 STARTING AND OPERATING

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
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 OFF the engine.
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.
STARTING AND OPERATING 309
5

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.
Permanent Transmission Limp Home Mode
Permanent Limp Home Mode will be activated if the
transmission enters temporary Limp Home Mode three
times. Follow the reset procedure described under “Tem-
porary Transmission Limp Home Mode” in this section.
In Permanent Limp Home Mode, PARK, REVERSE, and
NEUTRAL will continue to operate. Second gear will
operate in the DRIVE position. The Malfunction Indicator
Light (MIL) may illuminate.
AUTOSTICK
Autostickis a driver-interactive transmission that offers
manual gear shifting to provide you with more control of
the vehicle. Autostickallows 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.
AutostickOperation
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.
310 STARTING AND OPERATING

NOTE:
•In Autostickmode, the transmission will only 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 Autostickmode 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 rightfor at least one second. The transmission will now
operate automatically, shifting between the five available
gears.
AutostickGeneral Information
•
You can start out in 1st or 2nd gear. The system will
ignore attempts to upshift at too low of a vehicle
speed.
•The transmission will automatically downshift to 1st
gear when coming to a stop.
•Starting out in 2nd gear is helpful in snowy or icy
conditions.
•Avoid using speed control when Autostickis en-
gaged.
•The transmission will not automatically shift up when
maximum engine speed is reached while Autostickis
engaged.

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.
314 STARTING AND OPERATING

BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic
brake systems. If either of the two hydraulic
systems loses normal capability, the remaining
system will still function. There will be some
loss of overall braking effectiveness. This may be evident
by increased pedal travel during application, greater
pedal force required to slow or stop, and potential
activation of the Brake Warning Light.
In the event power assist is lost for any reason (for
example, repeated brake applications with the engine off)
the brakes will still function. The effort required to brake
the vehicle will be much greater than that required with
the power system operating.
Anti-Lock Brake System
The Anti-Lock Brake System provides increased vehicle
stability and brake performance under most braking
conditions. The system automatically “pumps” the
brakes during severe braking conditions to prevent
wheel lock-up.
The electronic brake force distribution (EBD) prevents the
rear wheels from over-braking and provides greater
control of available braking forces applied to the rear
axle.
When the vehicle is driven over 7 mph (11 km/h), you
may also hear a slight clicking sound as well as some
related motor noises. These noises are the system per-
forming its self check cycle to ensure that the ABS system
is working properly. This self check occurs each time the
vehicle is started and accelerated past 7 mph (11 km/h).
STARTING AND OPERATING 317

TCS (Traction Control System)
This system monitors the amount of wheel spin of each
driven wheel. If wheel spin is detected, brake pressure is
applied to the slipping wheel(s) and engine power is
reduced to provide enhanced acceleration and stability.
BAS (Brake Assist System)
This system complements the Anti-Lock Brake System
(ABS) by optimizing the vehicle braking capability dur-
ing emergency braking maneuvers. This system detects
an emergency braking situation by sensing the rate and
amount of brake application and then applies optimum
pressure to the brakes. This can help reduce braking
distances.
Applying the brakes very quickly results in the best BAS
assistance. To receive the benefits of this system, you
must apply continuous brake pedal pressure during thestopping sequence. Do not reduce brake pedal pressure
unless braking is no longer desired. Once the brake pedal
is released, the BAS is deactivated.
WARNING!
The BAS (Brake Assist System) cannot prevent the
natural laws of physics from acting on the vehicle,
nor can it increase the traction afforded by prevailing
road conditions. The BAS cannot prevent accidents,
including those resulting from excessive speed in
turns, driving on very slippery surfaces, or hydro-
planing. Only a safe, attentive, and skillful driver can
prevent accidents. The capabilities of a BAS-
equipped vehicle must never be exploited in a reck-
less or dangerous manner that could jeopardize the
user’s safety or the safety of others.
