clutch DODGE CHALLENGER SRT 2015 3.G Owners Manual

At the conclusion of each track event, it is recommended
that a brake bleed procedure be performed to maintain
the pedal feel and stopping capability of your Brembo
High Performance brake system.
It is recommended that each track outing end with a
minimum of one cool down lap using minimal braking.
Change the differential and manual transmission fluid
after every five hours of track use. Refer to “Maintaining
Your Vehicle” for fluid levels & specifications.
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 the suspension
system, brake system, prop shaft, and half shaft boots
should be inspected for wear or damage after every track
event.
Track usage results in increased operating temperatures
of the engine, transmission, clutch, driveline and brake
system. This increased operating temperature may affect
Noise Vibration Harshness (NVH) countermeasures de-
signed into your vehicle. New components may need to
be installed to return the system to the original NVH
performance.
Recommended tire pressure for track use:
•
Challenger/Charger: 40 psi hot, 32 psi front, 30 psi rear
cold

•When leaving the vehicle, always make sure the
ignition is in the OFF position, remove the Key Fob
from the vehicle, and lock the vehicle.
• Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Leaving children in
a vehicle unattended is dangerous for a number of
reasons. A child or others could be seriously or
fatally injured. Children should be warned not to
touch the parking brake, brake pedal or the trans-
mission gear selector.

Do not attempt to push or tow your vehicle to get it
started. Unburned fuel could enter the catalytic con-
verter and once the engine has started, ignite and
damage the converter and vehicle. If the vehicle has
a discharged battery, booster cables may be used to
obtain a start from another vehicle. This type of start
can be dangerous if done improperly, so follow the
procedure carefully. Refer to “Jump-Starting” in
“What To Do In Emergencies” for further informa-
tion.
Automatic Transmission — If Equipped

STARTING AND OPERATING 347

CAUTION!
•Never drive with your foot resting on the clutch
pedal, or try to hold the vehicle on a hill with the
clutch pedal partially engaged, as this will cause
abnormal wear on the clutch. Refer to “Electronic
Brake Control System/Hill Start Assist” in “Start-
ing And Operating” for further information.
• Failure to press the clutch pedal fully to the floor
may cause increased shift efforts, and may result in
damage to the clutch and transmission.
• Do not rest your hand on the shift lever while
driving, as this may result in transmission synchro-
nizer damage.
• Do not attempt to shift the transmission if the rear
wheels are spinning due to loss of traction. Dam-
age to the transmission may occur. NOTE:
During cold weather, you may experience in-
creased effort in shifting until the transmission fluid
warms up. This is normal.

STARTING AND OPERATING 349

NOTE:
•Your vehicle is equipped with a transmission reverse
inhibitor system. When vehicle speed is greater than
3 mph (5 km/h), the reverse inhibitor activates to help
prevent shifts into REVERSE. When at a complete stop,
you may notice lighter shift efforts into REVERSE with
the ignition switch in the ON position (RUN position
for Keyless Enter-N-Go) as compared to the LOCK
position (OFF position for Keyless Enter-N-Go). This is
normal operation of the transmission reverse inhibitor
system.
• Due to the high performance nature of your drivetrain,
you may hear your transmission. This can be most
noticeable when the vehicle is idling in NEUTRAL
with the clutch engaged (clutch pedal released), but it
may also be heard when driving at low engine RPM. Also, this may be more noticeable when the transmis-
sion is warm. This is a normal condition and is not an
indication of a problem with your clutch or transmis-
sion.
Shifting
Fully press the clutch pedal and lift your foot off the
accelerator pedal before shifting gears. As you release the
clutch pedal, lightly press the accelerator pedal. Damage
to the transmission or clutch may occur if you do not
fully press the clutch pedal and lift off of the accelerator
pedal when shifting.
The six-speed manual transmission has a spring that
centers the shift lever near third and fourth gear. This
spring helps you know which gear you are in when you
are shifting. Be careful when shifting from first to second
or downshifting from sixth to fifth.
The spring will try to pull the shift lever toward third and
fourth gear. Make sure you move the shift lever into
350 STARTING AND OPERATING

1–4 Skip Shift
There are times when you must shift the transmission
directly from first gear to fourth gear instead of from first
gear to second gear. This is to help you get the best
possible fuel economy from your vehicle. This occurs
when the engine coolant (antifreeze) is higher than 106°F
(41°C), vehicle speed is greater than 19 mph (30 km/h)
but less than 21 mph (34 km/h), and the transmission is
in first gear, and the accelerator is at ¼ throttle or less.
After you shift the transmission to fourth gear, you can
press the clutch in and shift to another forward gear.
Downshifting
To maintain a safe speed and prolong brake life, down-
shift to maintain a safe speed when descending a steep
grade.
WARNING!
Skipping more than one gear while downshifting,
could cause you to lose control of your vehicle. You
could have a collision.
CAUTION!
•If you skip more than one gear while downshifting
or downshift at too high an engine speed, you
could damage the engine, transmission, or clutch.
• Do not downshift into first gear when the vehicle is
moving faster than 15 mph (24 km/h), as you could
damage the engine and/or clutch.
