2010 DODGE CHALLENGER SRT torque

A feature of the TCS system functions similar to a
limited-slip differential and controls the wheel spin across
a driven axle. If one wheel on a driven axle is spinning
faster than the other, the system will apply the brake of
the spinning wheel. This will allow more engine torque to
be applied to the wheel that is not spinning. This feature
remains active even if TCS and ESP are in the “Partial Off”
or “Full Off” modes. Refer to “Electronic Stability Pro-
gram (ESP)” in this section for more information.
NOTE:The LSD is a true LSD and the TCS function is
similar to a limited-slip differential.
Brake Assist System (BAS)
This system complements the ABS by optimizing the
vehicle braking capability during emergency braking
maneuvers. This system detects an emergency braking
situation by sensing the rate and amount of brake appli-
cation 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 result-
ing from excessive speed in turns, driving on very
slippery surfaces, or hydroplaning. Only a safe, atten-
tive, 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.

sand, or gravel, it may be desirable to switch to the
“Partial Off” mode by momentarily pressing the “ESP
OFF” switch. Once the situation requiring “Partial Off”
mode is overcome, turn the ESP ON again by momen-
tarily pressing the “ESP OFF” switch. 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, press and hold the
“ESP OFF” switch for five seconds while the vehicle is
stopped with the engine running. After five seconds, a
chime will sound, the “ESP/TCS Indicator Light” will
illuminate, and theESP OFFmessage will display in the
vehicle odometer. Press and release the TRIP ODOM-
ETER button located on the instrument cluster to clear
this message. The “ESP OFF” message may appear in the
Electronic Vehicle Information Center (EVIC). Refer to “Electronic Vehicle Information Center (EVIC)” in “Un-
derstanding Your Instrument Panel” for further informa-
tion. To turn ESP ON again, momentarily press the “ESP
OFF” switch.
NOTE:
TheESP OFF message will display and the
audible chime will sound when the shift lever 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
reduction and stability features are cancelled. There-
fore, the enhanced vehicle stability offered by ESP is
unavailable.
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 pressing the
“ESP OFF” switch.
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 Indi-
cator 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.

RECREATIONAL TOWING
(BEHIND MOTORHOME, ETC.)
Recreational towing is allowed ONLY if the driveshaft
is removed.Towing with the rear wheels on the ground
while the driveshaft is connected can result in severe
transmission damage.
WARNING!
If the driveshaft is removed, the vehicle can roll even
if the transmission is in PARK, which could cause
serious injury or death. The parking brake must be firmly engaged and the
wheels chocked during driveshaft removal and installa-
tion. The parking brake must remain engaged unless the
vehicle is securely and properly connected to the tow
vehicle, or the driveshaft is completely reinstalled. See
your authorized dealer for proper driveshaft removal
and reinstallation procedures, including flange orienta-
tion/alignment, use of thread-locking compound, proper
bolt torque specifications, etc.5
STARTING AND OPERATING 313

If you notice fluid loss or gear shift malfunction, have
your authorized dealer check the transmission fluid level.
CAUTION!
•Using a transmission fluid other than the manu-
facturer’s recommended fluid may cause deterio-
ration in transmission shift quality and/or torque
converter shudder. Using a transmission fluid
other than that recommended by the manufacturer
will result in more frequent fluid and filter
changes. Refer to “Fluids, Lubricants, and Genu-
ine Parts” in “Maintaining Your Vehicle” for fur-
ther information.(Continued)
CAUTION! (Continued)
•The fluid level is preset at the factory and it does
not require adjustment under normal operating
conditions. If a transmission fluid leak occurs,
visit your authorized dealer immediately. Severe
damage to the transmission may occur. Your au-
thorized dealer has the proper tools to adjust the
fluid level accurately.
Fluid and Filter Changes
Refer to “Maintenance Schedule” for further information.
If the transmission is disassembled for any reason, the
fluid and filter should be changed.
Selection of Lubricant
It is important that the proper lubricant is used in the
transmission to assure optimum transmission perfor-
mance. Use only manufacturer ’s recommended transmis-
sion fluid. Refer to “Fluids, Lubricants, and Genuine
