NOTE:After launch mode has been aborted, ESC will
return to its current ESC mode.
CAUTION!
Do not attempt to shift when the drive wheels are
spinning and do not have traction. Damage to the
transmission may occur.
Guidelines For Track Use
NOTE: Because of the extreme conditions encountered
during track use, any damage or wear associated with
track use may not be covered by warranty.
• If your SRT vehicle is equipped with Drive Modes, they
will alter the vehicle’s performance in various driving
situations. It is recommended that your vehicle operates
in SPORT or TRACK modes during the track event.
• Prior to each track event/day, verify all fluids are at the
correct levels. Refer to “Fluid Capacities” in “Technical
Specifications” for further information.
• Prior to each track event, verify the front and rear brake
pads have more than ½ pad thickness remaining. If the
brake pads require changing, please burnish prior to
track outing at full pace. NOTE:
Use of DOT 4 brake fluid is suggested for extended
track usage due to increased thermal capacity.
• At the conclusion of each track event, it is recommended
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 one 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 endur-
ance. However, it is recommended that suspension
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 temperatures
of the engine, transmission, clutch – if equipped, drive-
line and brake system. This may affect noise (NVH)

countermeasures designed into your vehicle. New com-
ponents may need to be installed to return the system to
the original NVH performance.
• Tire pressure:
• 40psi (276kpa) hot, recommended 32psi (221kpa) front,
30psi (207 kpa) rear cold
NOTE: It is recommended that you target 40psi (276kpa)
Hot Tire Pressure at the conclusion of each track session.
Starting at 32psi (221kpa) Front and 30psi (207 kpa) Rear
Cold and adjusting based on ambient & track conditions is
recommended. Tire pressure can be monitored via the
instrument cluster display and can assist with adjustments.
Track burnishing your brakes:
To avoid “green lining fade” during track use, the brake
pads and rotors must have a thermal burnish for factory
installed components or when new brake friction compo-
nents are installed:
1. Use one track session to burnish brakes by driving at 75% speed. Brake at approximately 0.60-0.80g max with-
out ABS intervention.
2. Lap the track in this manner until you start smelling the brakes. Continue for another half lap at speed, then do a two lap cool down with minimal brake applies. Make
sure the brakes are not smoking. If they are, do another
cool down lap.
3. Do not continue for more than one full burnishing lap after you start smelling the brakes. Do not get them
smoking heavily. This will get them too hot and affect
their life negatively in future track use.
4. Allow vehicle to sit and cool in the paddock for at least 30 min. If an infrared thermal gun is available, allow
rotors to cool to 200°F (93.3°C) before going back out.
5. There should be a thin ash layer when inspecting the pads installed in the caliper. Having the ash layer go
more than half the thickness of the pad material indi-
cates too aggressive of a burnish.
6. Sometimes, a second burnish session is required. If the pads start smelling in the next track session, reduce
speed and braking decel to burnish targets and follow
steps two through four.
7. New pads installed on old rotors still need to be burnished. New rotors installed with old pads should be
burnished at the track or street driven for 300 city miles
to develop an adequate lining transfer layer on the rotor
surface prior to track use.
234 STARTING AND OPERATING

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 con-
tainer to avoid contamination from foreign matter or
moisture.
Refer to “Fluids And Lubricants” in “Technical Specifica-
tions” for further information.
WARNING!
•Use only manufacturer’s recommended brake fluid.
Refer to “Fluids And Lubricants” in “Technical
Specifications” for further information. Using the
(Continued)
WARNING! (Continued)
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 cylin-
der 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 brak-
ing, 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.

SERVICING AND MAINTENANCE 341

Wheel And Wheel Trim Care
All wheels and wheel trim, especially aluminum and
chrome plated wheels, should be cleaned regularly using
mild (neutral Ph) soap and water to maintain their luster
and to prevent corrosion. Wash wheels with the same soap
solution recommended for the body of the vehicle and
remember to always wash when the surfaces are not hot to
the touch.
Your wheels are susceptible to deterioration caused by salt,
sodium chloride, magnesium chloride, calcium chloride,
etc., and other road chemicals used to melt ice or control
dust on dirt roads. Use a soft cloth or sponge and mild soap
to wipe away promptly. Do not use harsh chemicals or a
stiff brush. They can damage the wheel’s protective coating
that helps keep them from corroding and tarnishing.
CAUTION!
Avoid products or automatic car washes that use acidic
solutions or strong alkaline additives or harsh brushes.
Many aftermarket wheel cleaners and automatic car
washes may damage the wheel’s protective finish.
Such damage is not covered by the New Vehicle
Limited Warranty. Only car wash soap, Mopar Wheel
Cleaner or equivalent is recommended.When cleaning extremely dirty wheels including excessive
brake dust, care must be taken in the selection of tire and
wheel cleaning chemicals and equipment to prevent dam-
age to the wheels. Mopar Wheel Treatment or Mopar
Chrome Cleaner or their equivalent is recommended or
select a non-abrasive, non-acidic cleaner for aluminum or
chrome wheels.
CAUTION!
Do not use scouring pads, steel wool, a bristle brush,
metal polishes or oven cleaner. These products may
damage the wheel’s protective finish. Such damage is
not covered by the New Vehicle Limited Warranty.
Only car wash soap, Mopar Wheel Cleaner or equiva-
lent is recommended.
NOTE: If you intend parking or storing your vehicle for an
extended period after cleaning the wheels with wheel
cleaner, drive your vehicle and apply the brakes to remove
the water droplets from the brake components. This activ-
ity will remove the red rust on the brake rotors and prevent
vehicle vibration when braking.
364 SERVICING AND MAINTENANCE

In the event power assist is lost for any reason (for
example, repeated brake applications with the engine
OFF), the brakes will still function. The effort required to
brake the vehicle will be much greater than that required
with the power system operating.
NOTE:Your vehicle is equipped with a high performance
braking system. The brake pads are a semi-metallic com-
pound, which offer superior fade resistance for consistent
operation. A compromise to using this type of brake pad is
that the brakes may produce more brake dust and may
squeal slightly under certain weather and operating con-
ditions (i.e., during light brake applications). These are
considered normal conditions.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to ensure that
the wheel is properly mounted to the vehicle. Any time a
wheel has been removed and reinstalled on the vehicle, the
lug nuts/bolts should be torqued using a properly cali-
brated torque wrench using a high quality six sided (hex)
deep wall socket.
