Right G-Force:
Measures the peak force on the right side of the
vehicle.
 Left G-Force:
Measures the peak force on the left side of the vehicle.
 Rear G-Force:
Measures the peak acceleration force on the rear of
the vehicle.
NOTE:Front, Right, Left, and Rear G-Forces are all peak values.
These readings can be reset by clearing peak G-Force on
the instrument cluster.
 Steering Wheel Angle
Steering Wheel Angle utilizes the steering angle sensor
to measure the degree of the steering wheel relative to
zero (straight ahead) reference angle. The zero degree
reference angle measurement indicates a steering
wheel straight ahead position.
The friction circle display shows instantaneous G-Force as
a highlight and previous G-Force as dots within the circle.
The system records previous G-Force for three minutes. If
there are multiple samples at a given point, the color of
the dot will darken from blue to red. Vectors more frequent
will show in red; infrequent vectors will show in blue.

DYNAMOMETER (DYNO)

Performance Pages — Dyno

The system will start drawing graphs for Power and Torque
(top chart) and Engine Speed (bottom chart). The graph
will fill to the right side of the page (based on History time
selected). Once the right side of the page is reached, the
graph will scroll with the right side always being the most
recent recorded sample.

DODGE DRIVE MODES — IF EQUIPPED
PERFORMANCE CONTROL —
I
F EQUIPPED
Your vehicle may be equipped with a Performance Control
feature which allows for coordinating the operation of
various vehicle systems depending upon the type of
driving behavior desired. The Performance Control feature
is controlled through the Uconnect system and may be
accessed by performing any of the following:
 Pushing the Super Track Pack button on the instru -
ment panel switch bank.
 Selecting “Performance Control” from the Apps menu.
 Selecting “Performance Control” from within the
Performance Pages menu. You will be able to enable, disable, and customize the
functionality of the Launch Control and Performance
Control Set-Up features within Performance Control.
To access information about the functionality of these
features through the Uconnect system, press the Info
button on the touchscreen.
NOTE:Dodge vehicles equipped with a 6.4L engine, except for
R/T Scat Pack 1320 6.4L non-widebody vehicles, will use
SRT Drive Modes rather than the Dodge Performance
Control Pages. Please refer to the following sections for
further information on the SRT Drive Modes.

Pressing the Drive Mode Set-Up button on the
touchscreen within the Performance Control screen
indicates the real-time status of the various systems.
Pressing the Sport Mode Set-Up, Drag Mode Set-Up
(1320 only), or Default Mode Set-Up buttons on the
touchscreen allows the driver to configure their individual
performance control and see how those configurations
affect the performance of the vehicle.

240SERVICING AND MAINTENANCE
BRAKE SYSTEM
In order to ensure brake system performance, all brake
system components should be inspected periodically
Úpage 224.
Fluid Level Check — Brake Master Cylinder
Check the fluid level in the master cylinder immediately if
the Brake System Warning Light indicates system failure.
Check the fluid level in the master cylinder when
performing underhood services.
Clean the top of the master cylinder area before removing
the cap. Add fluid to bring the level up to the top of the
“FULL” mark on the side of the master cylinder reservoir.
Overfilling of fluid is not recommended because it may
cause leaking in the system.
Add enough fluid to bring the level up to the requirements
described on the brake fluid reservoir. With disc brakes,
fluid level can be expected to fall as the brake pads wear.
However, low fluid level may be caused by a leak and a
checkup may be needed. Use only brake fluid that has been recommended by the
manufacturer, and has been kept in a tightly closed
container to avoid contamination from foreign matter or
moisture
Úpage 278.
CLUTCH HYDRAULIC SYSTEM — MANUAL
T
RANSMISSION (IF EQUIPPED)
The clutch hydraulic system is fed by a segregated volume
of fluid within the brake system master cylinder reservoir.
In the event of leakage or wear, use only the
manufacturer's recommended brake fluid
Úpage 278.
MANUAL TRANSMISSION — IF EQUIPPED
Fluid Level Check
Check the fluid level by removing the fill plug on the left
side of the transmission. The fluid level should be
1/4 inch (6.4mm) below the bottom of the fill hole.
Add fluid, if necessary, to maintain the proper level
Úpage 278.
Change Transmission Fluid
If contaminated with water, change the fluid immediately.
See an authorized dealer for service.
For the proper maintenance intervals
Úpage 224.
WARNING!
Riding the brakes can lead to brake failure and possibly
a collision. Driving with your foot resting or riding on the
brake pedal can result in abnormally high brake
temperatures, excessive lining wear, and possible brake
damage. You would not have your full braking capacity
in an emergency.
WARNING!
 Use only manufacturer's recommended brake fluid Úpage 278. Using the wrong type of brake fluid can
severely damage your brake system and/or impair its
performance. The proper type of brake fluid for your
vehicle is also identified on the original factory
installed hydraulic master cylinder reservoir.
 To avoid contamination from foreign matter or mois -
ture, use only new brake fluid or fluid that has been
in a tightly closed container. Keep the master
cylinder reservoir cap secured at all times. Brake
fluid in a open container absorbs moisture from the
air resulting in a lower boiling point. This may cause
it to boil unexpectedly during hard or prolonged
braking, resulting in sudden brake failure. This could
result in a collision.
 Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing the
brake fluid to catch fire. Brake fluid can also damage
painted and vinyl surfaces, care should be taken to
avoid its contact with these surfaces.
 Do not allow petroleum based fluid to contaminate
the brake fluid. Brake seal components could be
damaged, causing partial or complete brake failure.
This could result in a collision.
CAUTION!
Using a transmission fluid other than the
manufacturer's recommended fluid may cause
deterioration in transmission shift quality and/or
damage to the transmission
