or TRACK settings within this mode. Steering wheel
mounted paddle shifters may be enabled or disabled
while in this mode as well.
• VALET MODE — To enter this mode the operator
must select it from the Drive Modes interface and enter
a four digit PIN code. The PIN code is not predeter-
mined, so the operator is free to select any four digit
numeric combination that will be easy to remember.
While in Valet Mode the following vehicle configura-
tions are set and locked to prevent unauthorized
modification:
• Engine limited to a lowest power output state.
• Transmission locks out access to first gear and shifts
earlier than normal. •
Traction, Steering and Suspension are forced to
STREET settings.
• Steering wheel mounted paddle shifters are disabled.
• The SRT Drive Modes are not available. Pushing the
SRT button will display the unlock keypad.
• The ESC Off button is disabled.
• The Launch Control button is disabled.
NOTE:
• To exit VALET Mode the operator must enter the same
four digit PIN that was used to enter the mode. The
unlock keypad can be accessed by either pushing the
SRT button or selecting to disable Valet on the
Uconnect touchscreen.
• The vehicle will restart with VALET active if VALET
was active when the vehicle was last shut down.
488 STARTING AND OPERATING

•ECO MODE — This mode modifies the vehicle’s
engine and transmission settings to provide improved
fuel economy at a trade-off with acceleration perfor-
mance. Increased engine exhaust noise and/or vibra-
tion may be noticed while Eco is active, this is normal
and will not damage the vehicle.
NOTE: Changing the Drive Mode will deactivate Eco.
Launch Control — If Equipped
This vehicle is equipped with a Launch Control system
that is designed to allow the driver to achieve maximum
vehicle acceleration in a straight line. Launch Control is a
form of traction control that manages tire slip while
launching the vehicle. This feature is intended for use
during race events on a closed course where consistent
quarter mile and zero to sixty times are desired. The
system is not intended to compensate for lack of driver
experience or familiarity with the race track. Use of this feature in low traction (cold, wet, gravel, etc.) conditions
may results in excess wheel slip outside this systems
control resulting in an aborted launch.
Preconditions:
•
Launch Control should not be used on public roads.
Always check track conditions and the surrounding
area.
• Launch Control is not available within the first 500
miles (805 km) of engine break-in.
• Launch Control should only be used when the engine
and transmission are at operating temperature.
• Launch Control is intended to be used on dry, paved
road surfaces only.

CAUTION!
Use on slippery or loose surfaces may cause damage
to vehicle components and is not recommended.
Launch Control is only available when the following
procedure is followed:
NOTE: Pushing the SRT button on the Select-Track
switch or pressing the “Apps” button on the touchscreen
are the two options to access launch control features.
Please refer to “SRT Drive Modes” in “Understanding
Your Instrument Panel” for further information.
1. Press the “Race Options” button on the touchscreen or push the LAUNCH button on the Select-Track switch.
2. Press the “Launch RPM Set-Up” button on the touch- screen. This screen will allow you to adjust your
launch RPM’s for optimum launch/traction. 3. Press the “Activate Launch Control” button on the
touchscreen, follow instructions in the Driver Informa-
tion Display (DID).
• Make sure the vehicle is not moving.
• Put vehicle in first gear.
• Steering wheel must be pointing straight.
• Vehicle must be on level ground.
• Apply Brake Pressure.
• While holding the brake, rapidly apply the accelera-
tor pedal to wide open throttle. The engine speed
will hold at the RPM that was set in the “Launch
RPM Set-up” screen.
NOTE: Messages will appear in the DID to inform the
driver if one or more of the above conditions have not
been met.
490 STARTING AND OPERATING

•Prior to each track event/day, verify all fluids are at
the correct levels. Refer to “Fluid Capacities” in “Main-
taining Your Vehicle” for further information.
• Prior to each track event, verify the front and rear
brake pads have more than ½ pad thickness remain-
ing. If the brake pads require changing, please burnish
prior to track outing at full pace.
• At the conclusion of each track event, it is recom-
mended that a brake bleed procedure is performed to
maintain the pedal feel and stopping capability of your
Brembo High Performance brake system.
• It is recommended that each track outing should end
with a minimum of 1 cool down lap using minimal
braking.
• If equipped with a removable lower front fascia grille,
it is recommended to remove it for track use during warm/hot weather to improve cooling airflow to
critical powertrain and cooling system components.
• All SRT vehicles are track tested for 24 hours of
endurance, however, it is recommended that suspen-
sion system, brake system, prop shaft, and ½ shaft
boots should be checked for wear or damage after
every track event.
• Track usage results in increased operating tempera-
tures of the engine, transmission, driveline and brake
system. This may affect noise (NVH) countermeasures
designed into your vehicle. New components may
need to be installed to return the system to the original
NVH performance.
• Tire pressure:
• 40psi (276kpa) hot, recommend 32psi (221kpa) front,
30psi (207 kpa) rear cold

standing water that is deeper than the bottom of
the tire rims mounted on the vehicle.
• Determine the condition of the road or the path
that is under water and if there are any obstacles in
the way before driving through the standing water.
• Do not exceed 5 mph (8 km/h) when driving
through standing water. This will minimize wave
effects.
• Driving through standing water may cause damage
to your vehicle’s drivetrain components. Always
inspect your vehicle’s fluids (i.e., engine oil, trans-
mission, axle, etc.) for signs of contamination (i.e.,
fluid that is milky or foamy in appearance) after
driving through standing water. Do not continue to
operate the vehicle if any fluid appears contami-
nated, as this may result in further damage. Such
(Continued)
CAUTION! (Continued)
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.
ELECTRIC POWER STEERING
The electric power steering system 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 electric steering system experiences a fault that
prevents it from providing assist, you will still have the
ability to steer the vehicle manually.
496 STARTING AND OPERATING

Alternate electric power steering efforts can be selected
through the Uconnect System. Refer to ”Customer Pro-
grammable Features” within “Uconnect Settings” in “Un-
derstanding Your Instrument Panel” for further informa-
tion.
WARNING!
Continued operation with reduced assist could pose
a safety risk to yourself and others. Service should be
obtained as soon as possible.If the Electric Power Steering warning icon is
displayed and the “SERVICE POWER STEER-
ING” or the “POWER STEERING ASSIST OFF
– SERVICE SYSTEM” message is displayed
within the Driver Information Display (DID), this indi-
cates the vehicle needs to be taken to the dealer for service. Refer to “Driver Information Display (DID)” in
“Understanding Your Instrument Panel” for further in-
formation.
NOTE:
•
Even if the power steering assistance is no longer
operational, it is still possible to steer the vehicle.
Under these conditions there will be a substantial
increase in steering effort, especially at low speeds and
during parking maneuvers.
• If the condition persists, see your authorized dealer for
service.
FUEL SAVER TECHNOLOGY — IF EQUIPPED
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.

STARTING AND OPERATING 497

WARNING!(Continued)
•Do not leave the Key Fob in or near the vehicle or
in a location accessible to children, and do not
leave the ignition of a vehicle equipped with
Keyless Enter-N-Go in the ACC or ON/RUN mode.
A child could operate power windows, other con-
trols, or move the vehicle.
• Be sure the parking brake is fully disengaged
before driving; failure to do so can lead to brake
failure and a collision.
• Always fully apply the parking brake when leav-
ing your vehicle, or it may roll and cause damage or
injury. Also be certain to leave the transmission in
PARK. Failure to do so may allow the vehicle to roll
and cause damage or injury.
CAUTION!
If the “Brake” Warning Light remains on with the
parking brake released, a brake system malfunction
is indicated. Have the brake system serviced by an
authorized dealer immediately.
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 func-
tion. However, there will be some loss of overall braking
effectiveness. You may notice increased pedal travel
during application, greater pedal force required to slow
or stop, and potential activation of the “Brake System
Warning Light.”
In the event power assist is lost for any reason (i.e.,
repeated brake applications with the engine off) the
500 STARTING AND OPERATING

•For vehicles equipped with the Driver Information
Display (DID), refer to “Driver Information Display
(DID)” in “Understanding Your Instrument Panel” for
further information.
• If disabling HSA using Uconnect Settings, refer to
“Uconnect Settings” in “Understanding Your Instru-
ment Panel” for further information.
For vehicles not equipped with the DID, perform the
following steps:
1. Center the steering wheel (front wheels pointing straight forward).
2. Shift the transmission into PARK.
3. Apply the parking brake.
4. Start the engine.
5. Rotate the steering wheel slightly more than one-half turn to the left. 6. Push the “ESC Off” button located in the lower switch
bank below the climate control four times within
twenty seconds. The “ESC Off Indicator Light” should
turn on and turn off two times.
7. Rotate the steering wheel back to center and then an additional slighty more than one-half turn to the right.
8. Turn the ignition switch to the OFF position and then back to the ON position. If the sequence was com-
pleted properly, the “ESC Off Indicator Light” will
blink several times to confirm HSA is disabled.
9. Repeat these steps if you want to return this feature to its previous setting.
Traction Control System (TCS)
This system monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, the TCS may
apply brake pressure to the spinning wheel(s) and/or
reduce engine power to provide enhanced acceleration

STARTING AND OPERATING 507

and stability. A feature of the TCS, Brake Limited Differ-
ential (BLD), functions similar to a limited slip differen-
tial 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. BLD may remain
enabled even if TCS and ESC are in a reduced mode.
Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESC cor-
rects for oversteering or understeering of the vehicle by
applying the brake of the appropriate wheel(s) to assist in
counteracting the oversteer or understeer condition. En-
gine power may also be reduced to help the vehicle
maintain the desired path.
ESC uses sensors in the vehicle to determine the vehicle
path intended by the driver and compares it to the actualpath of the vehicle. When the actual path does not match
the intended path, ESC applies the brake of the appro-
priate wheel to assist in counteracting the oversteer or
understeer condition.
•
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 “ESC Activation/Malfunction Indicator Light” lo-
cated in the instrument cluster will start to flash as soon
as the ESC system becomes active. The “ESC Activation/
Malfunction Indicator Light” also flashes when the TCS
is active. If the “ESC Activation/Malfunction 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.
508 STARTING AND OPERATING

ESC Operating Modes
NOTE:Depending upon model and mode of operation,
the ESC system may have multiple operating modes.
ESC On
This is the normal operating mode for the ESC. When-
ever the vehicle is started, the ESC system will be in this
mode. This mode should be used for most driving
conditions. Alternate ESC modes should only be used 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. This mode
may modify TCS and ESC thresholds for activation,
which allows for more wheel spin than normally al-
lowed. This mode may be useful if the vehicle becomes
stuck. To enter the “Partial Off” mode, momentarily push the
“ESC Off” switch and the “ESC Off Indicator Light” will
illuminate. To turn the ESC on again, momentarily push
the “ESC Off” switch and the “ESC Off Indicator Light”
will turn off.
NOTE:
For vehicles with multiple partial ESC modes a
momentary button push will toggle the ESC mode.
Multiple momentary button pushed may be required to
return to ESC On.
NOTE:
• When in “Partial Off” mode, the TCS functionality of
ESC, (except for the limited slip feature described in
the TCS section), has been disabled and the “ESC Off
Indicator Light” will be illuminated. When in “Partial
Off” mode, the engine power reduction feature of TCS
is disabled, and the enhanced vehicle stability offered
by the ESC system is reduced.
