2012 CHRYSLER 300 power steering

POWER STEERING
Your vehicle is equipped with an electro-hydraulic power
steering system that will give you good vehicle response
and increased ease of maneuverability in tight spaces.
The system will vary its assist to provide light efforts
while parking and good feel while driving. If the electro-
hydraulic power steering system experiences a fault that
prevents it from providing power steering assist, then the
system will provide mechanical steering capability.
CAUTION!
Extreme steering maneuvers may cause the electri-
cally driven pump to reduce or stop power steering
assistance in order to prevent damage to the system.
Normal operation will resume once the system is
allowed to cool.If the “SERVICE POWER STEERING SYSTEM”
message and a flashing icon are displayed on
the EVIC screen, it indicates that the vehicle
needs to be taken to the dealer for service. It is
likely the vehicle has lost power steering assistance. Refer
to “Electronic Vehicle Information Center (EVIC)” in
“Understanding Your Instrument Panel” for further in-
formation.
If the “POWER STEERING SYSTEM OVER TEMP” mes-
sage and an icon are displayed on the EVIC screen, it
indicates that extreme steering maneuvers may have
occurred, which caused an over temperature condition in
the power steering system. You will lose power steering
assistance momentarily until the over temperature con-
dition no longer exists. Once driving conditions are safe,
then pull over and let vehicle idle for a few moments
until the light turns off. Refer to “Electronic Vehicle
Information Center (EVIC)” in “Understanding Your
Instrument Panel” for further information.

STARTING AND OPERATING 373

NOTE:
•Even if power steering assistance is no longer opera-
tional, it is still possible to steer the vehicle. Under
these conditions there will be a substantial increase in
steering effort, especially at very low vehicle speeds
and during parking maneuvers.
•If the condition persists, see your authorized dealer for
service.
MULTI-DISPLACEMENT SYSTEM (MDS) (IF
EQUIPPED) — 5.7L ENGINE ONLY
This feature offers improved fuel economy by shutting
off four of the engine’s eight cylinders during light load
and cruise conditions. The system is automatic with no
driver inputs or additional driving skills required.
NOTE:The MDS system may take some time to return
to full functionality after a battery disconnect.
374 STARTING AND OPERATING

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 collisions, including those re-
sulting from excessive speed in turns, driving on
very slippery surfaces, or hydroplaning. The capa-
bilities 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 Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. The ESC
corrects for oversteering and understeering the vehicle
by applying the brake of the appropriate wheel. Engine
power may also be reduced to assist in counteracting the
condition of oversteer or understeer and help the vehicle
maintain the desired path.
The ESC 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 ESC 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.

STARTING AND OPERATING 381

Synchronizing ESC
If the power supply is interrupted (battery
disconnected or discharged), the “ESC
Activation/Malfunction Indicator 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 “ESC Activation/
Malfunction Indicator Light” should go out. However, if
the light remains on, have the ESC and BAS checked at
your authorized dealer as soon as possible.

8. Disconnect the positive(+)jumper cable from the
positive(+)post of the booster battery.
9. Disconnect the positive(+)end of the jumper cable
from the remote positive(+)post of the discharged
vehicle.
If frequent jump-starting is required to start your vehicle
you should have the battery and charging system in-
spected at your authorized dealer.
CAUTION!
Accessories that can be plugged into the vehicle
power outlets draw power from the vehicle’s battery,
even when not in use (i.e., cellular phones, etc.).
Eventually, if plugged in long enough, the vehicle’s
battery will discharge sufficiently to degrade battery
life and/or prevent the engine from starting.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand, or snow, it
can often be moved by a rocking motion. Turn your
steering wheel right and left to clear the area around the
front wheels. Then shift back and forth between DRIVE
and REVERSE. Using minimal accelerator pedal pressure
to maintain the rocking motion, without spinning the
wheels, is most effective.
CAUTION!
Racing the engine or spinning the wheels may lead to
transmission overheating and failure. Allow the en-
gine to idle with the shift lever in NEUTRAL for at
least one minute after every five rocking-motion
cycles. This will minimize overheating and reduce
the risk of transmission failure during prolonged
efforts to free a stuck vehicle.

MAINTENANCE PROCEDURES
The pages that follow contain therequiredmaintenance
services determined by the engineers who designed your
vehicle.
Besides those maintenance items specified in the fixed
maintenance schedule, there are other components which
may require servicing or replacement in the future.
CAUTION!
•Failure to properly maintain your vehicle or per-
form repairs and service when necessary could
result in more costly repairs, damage to other
components or negatively impact vehicle perfor-
mance. Immediately have potential malfunctions
examined by an authorized Chrysler Group LLC
dealership or qualified repair center.
(Continued)
CAUTION! (Continued)
•Your vehicle has been built with improved fluids
that protect the performance and durability of
your vehicle and also allow extended maintenance
intervals. Do not use chemical flushes in these
components as the chemicals can damage your
engine, transmission, power steering or air condi-
tioning. Such damage is not covered by the New
Vehicle Limited Warranty. If a flush is needed
because of component malfunction, use only the
specified fluid for the flushing procedure.
