ESP CHRYSLER 300 C 2009 1.G Service Manual

“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
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.
326 STARTING AND OPERATING

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.
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 key to LOCK, then start the engine.
•Shift into DRIVE and resume driving.

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.
When frequent transmission shifting occurs when using
the Overdrive range, such as when operating the vehicle

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 steering
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.

ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle is equipped with an advanced electronic
brake control system that include ABS (Anti-Lock Brake
System), TCS (Traction Control System), BAS (Brake
Assist System), and ESP (Electronic Stability Program).
All four of these systems work together to enhance
vehicle stability and control in various driving condi-
tions.
Anti-Lock Brake System (ABS)
This system aids the driver in maintaining vehicle control
under adverse braking conditions by controlling hydrau-
lic brake pressure. This prevents wheel lock-up to help
avoid skidding on slippery surfaces during braking.
Refer to “Anti-Lock Brake System” in Section 5 of this
manual.
WARNING!
The ABS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase the
traction afforded by prevailing road conditions. The
ABS cannot prevent accidents, including those re-
sulting from excessive speed in turns, driving on
very slippery surfaces, or hydroplaning. Only a safe,
attentive, and skillful driver can prevent accidents.
The capabilities of an ABS-equipped vehicle must
never be exploited in a reckless or dangerous manner
that could jeopardize the user’s safety or the safety of
others.
Traction Control System (TCS)
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.
STARTING AND OPERATING 343
5

Brake Assist System (BAS)
This system complements the ABS by optimizing the
vehicle braking capability during emergency brake ma-
neuvers. This system detects an emergency braking situ-
ation 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 the
stopping 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 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 re-
sulting from excessive speed in turns, driving on
very slippery surfaces, or hydroplaning. Only a safe,
attentive, and skillful driver can prevent accidents.
The capabilities of a BAS-equipped vehicle must
never be exploited in a reckless or dangerous manner
that could jeopardize the user’s safety or the safety of
others.
Electronic Stability Program (ESP)
This system enhances directional control and stability of
the vehicle under various driving conditions. The ESP
corrects for oversteering and understeering the vehicle
by applying the brake of the appropriate wheel. Engine
344 STARTING AND OPERATING

power may also be reduced to assist in counteracting the
condition of oversteer or understeer and help the vehicle
maintain the desired path.
The ESP uses sensors in the vehicle to determine the path
that the driver intends to steer the vehicle and compares
it to the actual path of the vehicle. When the actual path
does not match the intended path, the ESP applies the
brake of the appropriate wheel to assist in counteracting
the condition of oversteer or understeer.
•Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
•Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.
The ESP/TCS Indicator Light located in the
instrument cluster, starts to flash as soon as the
tires lose traction and the ESP system becomes
active. The ESP/TCS Indicator Light alsoflashes when the TCS is active. If the ESP/TCS Indicator
Light begins to flash during acceleration, ease up on the
accelerator and apply as little throttle as possible. Be sure
to adapt your speed and driving to the prevailing road
conditions.
WARNING!
The ESP cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase the
traction afforded by prevailing road conditions. The
ESP cannot prevent accidents, including those result-
ing from excessive speed in turns, driving on very
slippery surfaces, or hydroplaning. Only a safe, at-
tentive, and skillful driver can prevent accidents. The
capabilities of an ESP-equipped vehicle must never
be exploited in a reckless or dangerous manner that
could jeopardize the user’s safety or the safety of
others.
STARTING AND OPERATING 345

The ESP system has two available operating modes:
ESP On
This is the normal operating mode for the ESP. Whenever
the vehicle is started, the ESP system will be in this mode.
This mode should be used for most driving conditions.
The ESP should only be turned OFF for specific reasons
as noted in the following paragraphs.
Partial Off
The “Partial Off” mode is intended for times when a
more spirited driving experience is desired. It is also
intended for driving in deep snow, sand, or gravel. This
mode disables the TCS portion of the ESP and raises the
threshold for ESP activation, which allows for more
wheel spin than what ESP normally allows.
The ESP OFF switch is located on the switch bank in the
center of the instrument panel. To enter the “Partial Off”
mode, momentarily depress the ESP OFF switch and the
“ESP/TCS Indicator Light” will illuminate. To turn theESP on again, momentarily depress the ESP OFF switch
and the “ESP/TCS Indicator Light” will turn off.
NOTE:To improve the vehicle’s traction when driving
with snow chains, or when starting off in deep snow,
sand, or gravel, it may be desirable to switch to the
“Partial Off” mode by momentarily depressing the ESP
ESP OFF Switch
346 STARTING AND OPERATING

OFF switch. Once the situation requiring “Partial Off”
mode is overcome, turn the ESP on again by momentarily
depressing the ESP OFF switch. This may be done while
the vehicle is in motion.
Synchronizing ESP
The Malfunction Indicator Light for the ESP is
combined with BAS indicator. If the power
supply is interrupted (battery disconnected or
discharged), the ESP/BAS Malfunction Indica-
tor Light may illuminate with the engine running. If this
should occur, turn the steering wheel completely to the
left and then to the right. The ESP/BAS Malfunction
Indicator Light should go out. However, if the light
remains on, have the ESP and BAS checked at your
authorized dealer as soon as possible.
ESP/BAS Malfunction Indicator Light and
ESP/TCS Indicator Light
The Malfunction Indicator Light for the ESP is
combined with the BAS indicator. The ESP/
BAS Malfunction Indicator Light and the ESP/
TCS Indicator Light in the instrument cluster
both come on when the ignition switch is turned to the
ON position. They should go out with the engine run-
ning.
The system will turn the ESP/BAS Malfunction Indicator
Light on continuously while the engine running if it
detects a malfunction in either the ESP or the BAS or
both. If the light remains on after several ignition cycles,
and you have driven the vehicle several miles (kilome-
ters) at speeds greater than 30 mph (48 km/h), and the
ESP is synchronized (refer to Synchronizing ESP), see
your authorized dealer as soon as possible to have the
problem diagnosed and corrected.

NOTE:
•The ESP/TCS Indicator Light and the ESP/BAS Mal-
function Indicator Light will turn on momentarily
each time the ignition switch is turned ON.
•Each time the ignition switch is turned ON, the ESP
system will be on even if it was turned off previously.
•The ESP control system will make buzzing or clicking
sounds when it is active. This is NORMAL; the sounds
will stop when ESP becomes inactive following the
maneuver that caused the ESP activation.
