2008 CHRYSLER 300 SRT Owners Manual

All vehicle wheels and tires must be the same size and
type and tires must be properly inflated to produce
accurate signals for the computer.
Anti-Lock Brake Light
The ABS light monitors the Anti-Lock Brake Sys-
tem. The light will come on when the ignition
switch is turned to the ON position and may stay on for
as long as four seconds.
If the ABS light remains on or comes on while driving, it
indicates that the Anti-Lock portion of the brake system
is not functioning and that service is required. However,
the conventional brake system will continue to operate
normally if the BRAKE warning light is not on.
If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefits of Anti-Lock
brakes. If the ABS light does not come on when the
Ignition switch is turned to the ON position, have the
bulb repaired as soon as possible.If both the Brake Warning Light and the ABS Light
remain on, the Anti-Lock brakes (ABS) and Electronic
Brake Force Distribution (EBD) systems are not function-
ing. Immediate repair to the ABS system is required.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.
STARTING AND OPERATING 319
5

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.
WARNING!
Continued operation with reduced power steering
assist could pose a safety risk to yourself and others.
Service should be obtained as soon as possible.
CAUTION!
Prolonged operation of the steering system at the end
of the steering wheel travel will increase the steering
fluid temperature and it should be avoided when
possible. Damage to the power steering pump may
occur.
ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle is equipped with an advanced electronic
brake control system commonly referred to as ESP. This
system includes the ABS (Anti-Lock Brake System), the
TCS (Traction Control System), the BAS (Brake Assist
System), and the ESP (Electronic Stability Program).
These systems work together to enhance both vehicle
stability and control in various driving conditions.
320 STARTING AND OPERATING

ABS (Anti-Lock Brake System)
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. For
more information about ABS, refer to “Anti-Lock Brake
System” in Section 5.WARNING!
The ABS (Anti-Lock Brake System) cannot prevent
the natural laws of physics from acting on the ve-
hicle, nor can it increase the traction afforded by
prevailing road conditions. The ABS cannot prevent
accidents, including those resulting 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.
STARTING AND OPERATING 321

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.
322 STARTING AND OPERATING

ESP (Electronic Stability Program)
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
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.
TheESP/TCS Indicator Light,located in the
instrument cluster, starts to flash as soon as the
tires lose traction and the ESP system becomes
active. TheESP/TCS Indicator Lightalso
flashes when TCS is active. If theESP/TCS Indicator
Lightbegins 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 (Electronic Stability Program) cannot pre-
vent 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 resulting 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
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.
The ESP system has 3 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 all driving situations.
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” button is located in the switch
bank near the top center of the instrument
panel. To enter the “Partial Off” mode, momen-
tarily depress the “ESP OFF” button and the
ESP/TCS Indicator Lightwill illuminate. To turn the
ESP ON again, momentarily depress theESP OFF
button and theESP/TCS Indicator Lightwill turn off.
324 STARTING AND OPERATING

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
OFF” button. Once the situation requiring “Partial Off”
mode is overcome, turn the ESP ON again by momen-
tarily depressing the “ESP OFF” button. This may be
done while the vehicle is in motion.
Full Off
This mode is intended for off-highway or off-road use
only and should not be used on any public roadways. In
this mode, all TCS and ESP stability features are turned
off. To enter the “Full Off” mode, depress and hold the
“ESP OFF” button for five seconds while the vehicle is
stopped with the engine running. After five seconds, a
chime will sound, theESP/TCS Indicator Lightwill
illuminate, and theESP OFFmessage will display in the
vehicle odometer. Press and release the TRIP ODOM-
ETER button located on the instrument cluster to clearthis message. The “ESP OFF” message may appear in the
Electronic Vehicle Information Center (EVIC). Refer to
“Electronic Vehicle Information Center (EVIC)” in Sec-
tion 4. To turn ESP ON again, momentarily depress the
ESP OFF Button.
NOTE:TheESP OFF,or “ESP System Deactivated”
message will display and the audible chime will sound
when the gear selector is moved into the PARK position
from any position other than PARK and then moved out
of the PARK position. This will occur when the message
was previously cleared.
WARNING!
In the ESP Full Off mode, the engine torque reduc-
tion and stability features are cancelled. Therefore,
the enhanced vehicle stability offered by ESP is
unavailable.
STARTING AND OPERATING 325

NOTE:When the ESP is switched off a feature of the
system remains active. This feature controls wheel spin
across an axle quite similarly to a limited slip differential.
If one wheel on an axle is spinning faster than the other,
the system will apply the brake of the spinning wheel
and allow more engine torque to be applied to the wheel
that is not spinning. To improve the vehicle’s traction
when driving with tire 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 OFF” button.WARNING!
With the ESP switched off, the enhanced vehicle
stability offered by ESP is unavailable. In an emer-
gency evasive maneuver, the ESP system will not
engage to assist in maintaining stability. The “Full
Off” ESP mode is intended for off-highway or off-
road only.
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
