traction control DODGE CHARGER SRT 2015 7.G User Guide

•The vehicle will restart with VALET active if VALET
was active when the vehicle was last shut down.
•Eco (Automatic Transmission only) — Eco modifies
the vehicle’s engine and transmission settings to pro-
vide improved fuel economy at a trade-off with accel-
eration performance. Increased engine exhaust noise
and/or vibration 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 Mode — 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.
NOTE:Launch mode is not available within the first 500
miles of engine break-in.
Preconditions:
•Launch control should not be used on public roads.
Always check track conditions and the surrounding
area.
•Launch Control is not available for the first 500 miles
of the vehicle’s life.
•Launch Control should only be used when the engine
and transmission are at operating temperature.
392 STARTING AND OPERATING

•Launch Control is intended to be used on dry, paved
road surfaces only. Use on slippery or loose surfaces
may cause damage to vehicle components and is not
recommended.
Launch Control is available when the following proce-
dure is followed:
1. Push the LAUNCH button on the center stack switch
bank.
NOTE:Pushing the SRT button on the center stack or
pressing the “SRT & Apps” button on the touchscreen are
two other options to access launch control features.
Please refer to “Uconnect® Settings” within your Own-
er ’s Manual on the DVD for further information.
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 Mode” button on the
touchscreen.
4. Make sure the vehicle is not moving.
5. Make sure the steering wheel is pointing straight.
6. Hold the brake and make sure the vehicle is in
“Drive”.
7. While holding the brake, rapidly apply the accelerator
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 Driver Information
Display (DID) to inform the driver if one or more of the
above conditions have not been met.
8. When conditions 5 through 8 have been met, the
Driver Information Display (DID) will read “Launch
Ready Release Brake”.

STARTING AND OPERATING 393

9. Keep the vehicle pointed straight.
Launch control will be active until the vehicle reaches
62 mph (100 km/h), at which point the ESC system will
return to its current ESC mode.
Launch control will abort before launch completion,
display “Launch Aborted” in the cluster and return to
ESC Full ON under any the following conditions:
•The accelerator pedal is released during launch. ESC
system continues in ESC Full ON.
•The ESC system detects that the vehicle is no longer
moving in a straight line. ESC system continues in ESC
Full ON.
•The “ESC OFF” button is pressed to change the system
to another mode. One press puts the ESC system into
ESC Full ON.
NOTE:After launch control 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 is not 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 oper-
ates in SPORT or TRACK modes during the track
event.
394 STARTING AND OPERATING

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
step 2-4.
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.
8. Rotors that pulsate during track use should be re-
placed. Resurfacing of the rotors is not recommended,
as it removes mass from the rotor, reducing its thermal
capacity. Resurfacing also thins the rotor cheek, mak-
ing it less robust and increasing the likelihood of
pulsation in further track use.
DRIVING ON SLIPPERY SURFACES
Acceleration
Rapid acceleration on snow covered, wet, or other slip-
pery surfaces may cause the driving wheels to pull
erratically to the right or left. This phenomenon occurs
when there is a difference in the surface traction under
the rear (driving) wheels.
WARNING!
Rapid acceleration on slippery surfaces is dangerous.
Unequal traction can cause sudden pulling of the rear
wheels. You could lose control of the vehicle and
possibly have a collision. Accelerate slowly and
carefully whenever there is likely to be poor traction
(ice, snow, wet mud, loose sand, etc.).
5
STARTING AND OPERATING 397

Traction
When driving on wet or slushy roads, it is possible for a
wedge of water to build up between the tire and road
surface. This is known as hydroplaning and may cause
partial or complete loss of vehicle control and stopping
ability. To reduce this possibility, the following precau-
tions should be observed:
•Slow down during rainstorms or when the roads are
slushy.
•Slow down if the road has standing water or puddles.
•Replace tires when tread wear indicators first become
visible.
•Keep tires properly inflated.
•Maintain sufficient distance between your vehicle and
the vehicle in front of you to avoid a collision in a
sudden stop.
Your vehicle may be equipped with a Limited Slip
Differential (LSD) that reduces, but does not eliminate,
the amount of wheel slip across a given axle for im-
proved handling.
DRIVING THROUGH WATER
Driving through water more than a few inches/
centimeters deep will require extra caution to ensure
safety and prevent damage to your vehicle.
Flowing/Rising Water
WARNING!
Do not drive on or across a road or path where water
is flowing and/or rising (as in storm run-off). Flow-
ing water can wear away the road or path’s surface
and cause your vehicle to sink into deeper water.
Furthermore, flowing and/or rising water can carry

398 STARTING AND OPERATING

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 perfor-
mance braking system. The brake pads are a semi-
metallic compound, 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 conditions (.i.e., during light brake applica-
tions) this is considered normal conditions.
ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle is equipped with an advanced electronic
brake control system that include Anti-Lock Brake Sys-
tem (ABS), Traction Control System (TCS), Brake Assist
System (BAS), and the Electronic Stability Control (ESC).
All four of these systems work together to enhance
vehicle stability and control in various driving condi-
tions.
Also, your vehicle may be equipped with Hill Start Assist
(HSA), Ready Alert Braking, and Rain Brake Support.
Anti-Lock Brake System (ABS)
The Anti-Lock Brake System (ABS) provides increased
vehicle stability and brake performance under most
braking conditions. The system automatically prevents
wheel lock, reduces stop distance, and enhances vehicle
control during stop.
When the vehicle is driven over 6 mph (10 km/h), you
may also hear a slight clicking sound as well as some
related motor noises. These noises are the system per-
forming its self-check cycle to ensure that the ABS is
working properly. This self-check occurs each time the
vehicle is started and accelerated past 6 mph (10 km/h).
406 STARTING AND OPERATING

Warning Light” does not come on when the ignition
switch is turned to the ON position, have the bulb
repaired as soon as possible.
If both the “Brake Warning Light” and the “Anti-Lock
Brake Warning Light” remain on, the ABS and Electronic
Brake Force Distribution (EBD) systems are not function-
ing. Immediate repair to the ABS system is required.
Consult with your authorized dealer service center as
soon as possible.
Traction Control System (TCS)
This system monitors the amount of wheel spin of each
driven wheel. If wheel spin is detected, brake pressure is
applied to the slipping wheel(s) and engine power is
reduced to provide enhanced acceleration and stability.
A feature of the TCS system, Brake Limited Differential
(BLD), 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. This feature remains active even if TCS
and ESC are in the “Sport Mode (Partial Off)” or#Track
Mode (Full Off)#mode. Refer to “Electronic Stability Con-
trol (ESC)” in this section for more information.
Brake Assist System (BAS)
This system complements the ABS by optimizing the
vehicle braking capability during emergency brake ma-
neuvers. This system detects an emergency braking situ-
ation by sensing the rate and amount of brake application
and then applies optimum pressure to the brakes. This
can help reduce braking distances.
Applying the brakes very quickly results in the best BAS
assistance. To receive the benefits of this system, you
must apply continuous brake pedal pressure during the
stopping sequence. Do not reduce brake pedal pressure
unless braking is no longer desired. Once the brake pedal
is released, the BAS is deactivated.
5
STARTING AND OPERATING 409

WARNING!
The BAS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase the
traction afforded by prevailing road conditions. The
BAS cannot prevent collisions, including those re-
sulting from excessive speed in turns, driving on
very slippery surfaces, or hydroplaning. The capa-
bilities of a BAS-equipped vehicle must never be
exploited in a reckless or dangerous manner that
could jeopardize the user’s safety or the safety of
others.
Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. The ESC
corrects for oversteering and understeering the vehicle
by applying the brake of the appropriate wheel. Engine
power may also be reduced to assist in counteracting the
condition of oversteer or understeer and help the vehicle
maintain the desired path.
The ESC uses sensors in the vehicle to determine the path
that the driver intends to steer the vehicle and compares
it to the actual path of the vehicle. When the actual path
does not match the intended path, the ESC applies the
brake of the appropriate wheel to assist in counteracting
the condition of oversteer or understeer.
•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.
410 STARTING AND OPERATING

WARNING!
The Electronic Stability Control System (ESC) cannot
prevent the natural laws of physics from acting on
the vehicle, nor can it increase the traction afforded
by prevailing road conditions. ESC cannot prevent
all accidents, including those resulting from exces-
sive speed in turns, driving on very slippery surfaces,
or hydroplaning. ESC also cannot prevent accidents
resulting from loss of vehicle control due to inappro-
priate driver input for the conditions. Only a safe,
attentive, and skillful driver can prevent accidents.
The capabilities of an ESC equipped vehicle must
never be exploited in a reckless or dangerous manner
which could jeopardize the user ’s safety or the safety
of others.
ESC Operating Modes
The ESC system has four available operating modes:
Street Mode
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
situations. The ESC should only be turned OFF for
specific reasons as noted in the following paragraphs.
Sport Mode
Sport Mode is intended for times when a more spirited
driving experience is desired. It is also can be useful
when wheel-slip may be desired such as driving out of
deep snow, sand, or gravel. This mode disables the TCS
portion of the ESC and raises the threshold for ESC
activation, which allows for more wheel spin than what
ESC normally allows.
5
STARTING AND OPERATING 411

Full Off
This mode is intended for off-highway or off-road use
only and should not be used on any public roadways. In
this mode, all TCS and ESC stability features are turned
OFF. To enter the “Full Off” mode, press and hold the
“ESC Off” switch for five seconds while the vehicle is
stopped with the engine running. After five seconds, a
chime will sound, the#ESC OFF Indicator Light#will
illuminate, and the “ESC off” message will appear in the
Driver Information Display (DID). Refer to “Driver In-
formation Display (DID)” in “Understanding Your In-
strument Panel” for further information. To turn ESC ON
again, momentarily press the “ESC Off” switch.
NOTE:The#ESC off#message will display and the
audible chime will sound when the shift lever is moved
into the PARK position from any position other than
PARK and then moved out of the PARK position. This
will occur when the message was previously cleared.
WARNING!
In the ESC “Full Off” mode, the engine torque
reduction and stability features are disabled. There-
fore, the enhanced vehicle stability offered by ESC is
unavailable. In an emergency evasive maneuver, the
ESC system will not engage to assist in maintaining
stability.$ESC Off$mode is intended for off-highway
or off-road use only.
NOTE:When the ESC is switched SPORT, the BLD system
remains active. This feature controls wheel spin across an
axle quite similarly to a limited slip differential. If one
wheel on an axle is spinning faster than the other, the
system will apply the brake of the spinning wheel and
allow more engine torque to be applied to the wheel that is
not spinning. To improve the vehicle’s traction when
driving with tire chains, or when starting off in deep snow,
sand, or gravel, it may be desirable to switch to the “Sport
Mode” by momentarily pressing the “ESC Off” switch.
