2015 CHRYSLER 300 brake

WARNING!
•Adaptive Cruise Control (ACC) is a convenience
system. It is not a substitute for active driving
involvement. It is always the driver ’s responsibil-
ity to be attentive of road, traffic, and weather
conditions, vehicle speed, distance to the vehicle
ahead; and, most importantly, brake operation to
ensure safe operation of the vehicle under all road
conditions. Your complete attention is always re-
quired while driving to maintain safe control of
your vehicle. Failure to follow these warnings can
result in a collision and death or serious personal
injury.
•The ACC system:
•Does not react to pedestrians, oncoming vehicles,
and stationary objects (e.g., a stopped vehicle in a
traffic jam or a disabled vehicle).
(Continued)
WARNING!(Continued)
•Cannot take street, traffic, and weather condi-
tions into account, and may be limited upon
adverse sight distance conditions.
•Does not always fully recognize complex driving
conditions, which can result in wrong or missing
distance warnings.
•Will bring the vehicle to a complete stop while
following a target vehicle and hold the vehicle
for 2 seconds in the stop position. If the target
vehicle does not start moving within two seconds
the ACC system will display a message that the
system will release the brakes and that the
brakes must be applied manually. An audible
chime will sound when the brakes are released.
You should switch off the ACC system:

WARNING!
Leaving the Adaptive Cruise Control (ACC) system
on when not in use is dangerous. You could acciden-
tally set the system or cause it to go faster than you
want. You could lose control and have a collision.
Always leave the system off when you are not using
it.
To Set A Desired ACC Speed
When the vehicle reaches the speed desired, push the
SET+button or the SET-button and release. The DID
will display the set speed.
If the system is Set when the vehicle speed is below
20 mph (32 km/h), the Set Speed shall be defaulted to
20 mph (32 km/h). If the system is Set when the vehicle
speed is above 20 mph (32 km/h), the Set Speed shall be
the current speed of the vehicle.
NOTE:ACC cannot be set if there is a stationary vehicle
in front of your vehicle in close proximity.
Remove your foot from the accelerator pedal. If you do
not, the vehicle may continue to accelerate beyond the set
speed. If this occurs:
•The message “DRIVER OVERRIDE” will display in
the DID.
•The system will not be controlling the distance be-
tween your vehicle and the vehicle ahead. The vehicle
speed will only be determined by the position of the
accelerator pedal.
To Cancel
The following conditions cancel the system:
•The brake pedal is applied.
•The CANCEL button is pushed.
•An Anti-Lock Brake System (ABS) event occurs.
178 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

•The shift lever/gear selector is removed from the
Drive position.
•The Electronic Stability Control/Traction Control Sys-
tem (ESC/TCS) activates.
•The vehicle parking brake is applied.
•Driver seatbelt is unbuckled at low speeds.
•Driver door is opened at low speeds.
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.
To Turn Off
The system will turn off and erase the set speed in
memory if:
•The Normal (Fixed Speed) Electronic Speed Control
ON/OFF button is pushed.
•The ignition is turned off.
•The Adaptive Cruise Control (ACC) On/Off button is
pushed.
To Resume
If there is a set speed in memory push the RES (resume)
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.
WARNING!
The Resume function should only be used if traffic
and road conditions permit. Resuming a set speed
that is too high or too low for prevailing traffic and
road conditions could cause the vehicle to accelerate
or decelerate too sharply for safe operation. Failure to
follow these warnings can result in a collision and
death or serious personal injury.
To Vary The Speed Setting
To Increase Speed
While ACC is set, you can increase the set speed by
pushing the SET+button.
The drivers preferred units can be selected through the
instrument panel settings if equipped. Refer to “Under-
standing Your Instrument Panel” for more information.
The speed increment shown is dependant on the chosen
speed unit of U.S. (mph) or Metric (km/h):
U.S. Speed (mph)
•Pushing the SET+button once will result in a 1 mph
increase in set speed. Each subsequent tap of the
button results in an increase of 1 mph.
•If the button is continually pushed, the set speed will
continue to increase in 5 mph increments until the
button is released. The increase in set speed is reflected
in the DID.
180 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

NOTE:
•When you override and push the SET+button or
SET-buttons, the new Set Speed will be the current
speed of the vehicle.
•When you use the SET-button to decelerate, if the
engine’s braking power does not slow the vehicle
sufficiently to reach the set speed, the brake system
will automatically slow the vehicle.
•The ACC system decelerates the vehicle to a full stop
when following a target vehicle. If an ACC host vehicle
follows a target vehicle to a standstill, after two
seconds the driver will either have to push the RES
(resume) button, or apply the accelerator pedal to
reengage the ACC to the existing Set Speed.
•The ACC system maintains set speed when driving up
hill and down hill. However, a slight speed change on
moderate hills is normal. In addition, downshifting
may occur while climbing uphill or descending down-
hill. This is normal operation and necessary to main-
tain set speed. When driving up hill and down hill, the
ACC system will cancel if the braking temperature
exceeds normal range (overheated).
Setting The Following Distance In ACC
The specified following distance for ACC can be set by
varying the distance setting between four bars (longest),
three bars (long), two bars (medium) and one bar (short).
Using this distance setting and the vehicle speed, ACC
calculates and sets the distance to the vehicle ahead. This
distance setting displays in the DID.
182 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

To decrease the distance setting, push the Distance Set-
ting — Decrease button and release. Each time the button
is pushed, the distance setting decreases by one bar
(shorter).
If there is no vehicle ahead, the vehicle will maintain the
set speed. If a slower moving vehicle is detected in the
same lane, the DID displays the “Sensed Vehicle Indica-
tor” icon, and the system adjusts vehicle speed automati-
cally to maintain the distance setting, regardless of the set
speed.
The vehicle will then maintain the set distance until:
•The vehicle ahead accelerates to a speed above the set
speed.
•The vehicle ahead moves out of your lane or view of
the sensor.
•The distance setting is changed.
•The system disengages. (Refer to the information on
ACC Activation).
The maximum braking applied by ACC is limited; how-
ever, the driver can always apply the brakes manually, if
necessary.
NOTE:The brake lights will illuminate whenever the
ACC system applies the brakes.
A Proximity Warning will alert the driver if ACC predicts
that its maximum braking level is not sufficient to
maintain the set distance. If this occurs, a visual alert
“BRAKE” will flash in the DID and a chime will sound
while ACC continues to apply its maximum braking
capacity.

UNDERSTANDING THE FEATURES OF YOUR VEHICLE 185

NOTE:The “Brake!” Screen in the DID is a warning for
the driver to take action and does not necessarily mean
that the Forward Collision Warning system is applying
the brakes autonomously.
Overtake Aid
When driving with ACC engaged and following a ve-
hicle, the system will provide an additional acceleration
up to the ACC set speed to assist in passing the vehicle.
This additional acceleration is triggered when the driver
utilizes the left turn signal and will only be active when
passing on the left hand side.
ACC Operation At Stop
If the ACC system brings your vehicle to a standstill
while following a target vehicle, if the target vehicle starts
moving within two seconds of your vehicle coming to a
standstill, your vehicle will resume motion without the
need for any driver action.
If the target vehicle does not start moving within two
seconds of your vehicle coming to a standstill, the ACC
with Stop system will cancel and the brakes will release.
