button and then remove your foot from the accelerator
pedal. The DID will display the last set speed.
NOTE:
•If your vehicle stays at standstill for longer than two
seconds, then the system will cancel and the brake
force will be ramped-out. The driver will have to apply
the brakes to keep the vehicle at a standstill.
• ACC cannot be resumed if there is a stationary vehicle
in-front of your vehicle in close proximity.3

standing Your Instrument Panel” for more information.
The speed decrement shown is dependant on the speed
of U.S. (mph) or Metric (km/h) units:
U.S. Speed (mph)
•Pushing the SET -button once will result ina1mph
decrease in set speed. Each subsequent tap of the
button results in a decrease of 1 mph.
• If the button is continually pushed, the set speed will
continue to decrease in 5 mph decrements until the
button is released. The decrease in set speed is re-
flected in the DID display.
Metric Speed (km/h)
• Pushing the SET -button once will result in a 1 km/h
decrease in set speed. Each subsequent tap of the
button results in a decrease of 1 km/h. •
If the button is continually pushed, the set speed will
continue to decrease in 10 km/h decrements until the
button is released. The decrease in set speed is re-
flected in the DID display.
To Cancel
The following conditions will cancel the Normal (Fixed
Speed) Electronic Speed Control without clearing the
memory:
• The brake pedal is applied.
• The CANCEL button is pushed.

head unit. When the shift up indicator is shown on the
display, the PSI is advising the driver to engage a higher
gear.
NOTE:The PSI is configured and turned on or off in the
head unit “Shift Light: Set Up” page.
The PSI indicator in the cluster information display
remains illuminated until the driver changes gear, or the
driving conditions return to a situation where changing
gear is not required, corresponding to the configured
RPMs in the head unit.
NOTE: Refer to “Uconnect Settings” in “Understanding
Your Instrument Panel” for further information on en-
abling, disabling, and configuring the Performance Shift
Indicator.

460 STARTING AND OPERATING

•Sport – Dry weather, on-road calibration. Performance
based tuning that provides a rear wheel drive feel but
with improved handling and acceleration over a two-
wheel drive vehicle. This feature will reset to AUTO on
an ignition cycle.
• Snow – Tuning set for additional stability in inclement
weather. Use on and off road on loose traction surfaces
such as snow. This feature will reset to AUTO upon an
ignition cycle.
• Auto – Fully automatic full time four-wheel drive
operation can be used on and off road. Balances
traction with seamless steering feel to provide im-
proved handling and acceleration over two-wheel
drive vehicles.
• Track – Track road calibration for use on high traction
surfaces. Driveline is maximized for traction. Some
binding may be felt on less forgiving surfaces. This
feature will reset to AUTO on an ignition cycle. •
To w – Use this mode for towing and hauling heavy
loads. Vehicle suspension will go to sport mode. Trailer
sway control is enabled in the ESC system. This feature
will reset to AUTO upon an ignition cycle.
Custom
This mode allows the driver to create a custom vehicle
configuration that is saved for quick selection of favorite
settings. The system will return to AUTO mode when the
ignition switch is cycled from RUN to OFF to RUN, if this
mode is selected. While in Custom Mode the Stability,
Transmission, Steering, Suspension, all-wheel drive set
up, and Paddle shifter settings may be configured
through the custom mode set-up.
NOTE: Please refer to “Drive Modes” in this section or
“Uconnect Settings” in “Understanding Your Instrument
Panel” for further information.

Drive Modes
484 STARTING AND OPERATING

•Off — disables steering wheel mounted paddle shift-
ers.
Stability Control
• Track — modifies traction control to optimize track
performance with the least stability control.
• Sport — turns off traction control and reduces stability
control.
• Street — provides full traction control and full stability
control.
Suspension
• Track — provides the firmest possible suspension
stiffness with the highest amount of comfort trade-off.
• Sport — provides a firmer suspension stiffness with
moderate comfort trade-off. •
Street — provides a balance of suspension stiffness
and ride comfort for typical daily driving.
Steering
• Track — provides the greatest amount of steering
feedback, requiring the highest amount of steering
effort.
• Sport — provides greater steering feedback, requiring
greater steering effort.
• Street — provides a balance of steering feedback and
steering effort.
• DEFAULT MODE — This mode will be activated
automatically when restarting the vehicle unless Valet
mode or ECO mode is active. This mode is for typical
driving conditions where the ABS and Transmission
will be operating in their STREET settings, which
cannot be changed while in this mode. The Steering

assist and Suspension (active dampening system) stiff-
ness may be configured to either the STREET, SPORT
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.
