80STARTING AND OPERATING
In the unlikely event of a malfunction of the EPB
system, a yellow EPB Warning Light will illuminate.
This may be accompanied by the Brake Warning
Light flashing. In this event, urgent service of the
EPB system is required. Do not rely on the parking
brake to hold the vehicle stationary.
Auto Park Brake
The Electric Park Brake (EPB) can be programmed
to be applied automatically whenever the vehicle is
at a standstill and the automatic transmission is
placed in PARK. Auto Park Brake is enabled and
disabled by customer selection through the
Customer Programmable Features section of the
Uconnect Settings Ú page 145.
Any single Auto Park Brake application can be
bypassed by pushing the EPB switch to the release
position while the transmission is placed in PARK.
SafeHold
SafeHold is a safety feature of the Electric Park
Brake (EPB) system that will engage the parking brake automatically if the vehicle is left unsecured
while the ignition is in ON/RUN.
The parking brake will automatically engage if all of
the following conditions are met:
The vehicle is at a standstill.
There is no attempt to press the brake pedal
and accelerator pedal.
The occupant status changed to unoccupied.
The driver door is open.
SafeHold can be temporarily bypassed by pushing
the EPB switch while the driver door is open. Once
manually bypassed, SafeHold will be enabled
again once the vehicle reaches 12 mph (20 km/h)
or the ignition is turned to the OFF position and
back to ON again.
Brake Service Mode
We recommend having your brakes serviced by an
authorized dealer. You should only make repairs
for which you have the knowledge and the right
equipment. You should only enter Brake Service
Mode during brake service.
When servicing your rear brakes, it may be
necessary for you or your technician to push
the rear piston into the rear caliper bore. With
the Electric Park Brake (EPB) system, this can
only be done after retracting the EPB actuator.
Fortunately, actuator retraction can be done easily
by entering the Brake Service Mode through the Uconnect Settings in your vehicle. This
menu-based system will guide you through the
steps necessary to retract the EPB actuator in
order to perform rear brake service.
Service Mode has requirements that must be met
in order to be activated:
The vehicle must be at a standstill.
The parking brake must be unapplied.
The transmission must be in PARK or NEUTRAL.
While in Service Mode, the EPB Warning Light will
flash continuously while the ignition is in ON/RUN.
When brake service work is complete, the following
steps must be followed to reset the park brake
system to normal operation:
Ensure the vehicle is at a standstill.
Press the brake pedal with moderate force.
Apply the EPB Switch.
WARNING!
Driving the vehicle with the parking brake
engaged, or repeated use of the parking brake
to slow the vehicle, may cause serious damage
to the brake system. Be sure the parking brake
is fully disengaged before driving; failure to do
so can lead to brake failure and a collision.
WARNING!
You can be badly injured working on or around
a motor vehicle. Do only that service work for
which you have the knowledge and the right
equipment. If you have any doubt about your
ability to perform a service job, take your vehicle
to a competent mechanic.

STARTING AND OPERATING81
(Continued)
AUTOMATIC TRANSMISSION IGNITION PARK INTERLOCK
(K
EYLESS VEHICLE)
This vehicle is equipped with an Ignition Park
Interlock, which requires the transmission to be in
PARK before the ignition can be turned to the OFF
position. Also, the transmission remains locked in
PARK whenever the ignition is in the OFF position.
BRAKE/TRANSMISSION SHIFT
I
NTERLOCK (BTSI) SYSTEM
This vehicle is equipped with a BTSI that holds the
transmission gear selector in PARK unless the
brakes are applied. To shift the transmission out of
PARK, the ignition must be turned to the ON/RUN
position (engine running or not), and the brake
pedal must be pressed. This vehicle is equipped
with an additional lock system that holds the
transmission gear selector in NEUTRAL (if vehicle
speed is approximately 0 mph (0 km/h)). To lock
the transmission gear selector in NEUTRAL, the
gear selector must stay in the NEUTRAL position
for approximately three seconds. To shift the
transmission into REVERSE or DRIVE the brake
pedal must be pressed.
WARNING!
It is dangerous to shift out of PARK or
NEUTRAL if the engine speed is higher than
idle speed. If your foot is not firmly pressing
the brake pedal, the vehicle could accelerate
quickly forward or in reverse. You could lose
control of the vehicle and hit someone or
something. Only shift into gear when the
engine is idling normally and your foot is firmly
pressing the brake pedal.
Unintended movement of a vehicle could
injure those in or near the vehicle. As with all
vehicles, you should never exit a vehicle while
the engine is running. Before exiting a vehicle,
always come to a complete stop, then apply
the parking brake, shift the transmission into
PARK, and turn the ignition off. When the igni -
tion is in the OFF position, the transmission is
locked in PARK, securing the vehicle against
unwanted movement.
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. Allowing
children to be 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 transmis -
sion gear selector.
Do not leave the key fob in or near the vehicle
(or in a location accessible to children), and do
not leave the ignition in the ON or RUN posi -
tion. A child could operate power windows,
other controls, or move the vehicle.
CAUTION!
Shift into or out of PARK or REVERSE only after
the vehicle has come to a complete stop.
Do not shift between PARK, REVERSE,
NEUTRAL, or DRIVE when the engine is above
idle speed.
Before shifting into any gear, make sure your
foot is firmly pressing the brake pedal.
WARNING!

button until one of the following appears in the
instrument cluster display:
Adaptive Cruise Control Off
When ACC is deactivated, the display will read
“Adaptive Cruise Control Off.”
Adaptive Cruise Control Ready
When ACC is activated, but the vehicle speed
setting has not been selected, the display will read
“Adaptive Cruise Control Ready.”
Adaptive Cruise Control Set
When the SET (+) or the SET (-) button is pushed,
the set speed will show in the instrument cluster
display.
The ACC screen may display once again if any of
the following ACC activity occurs:
System Cancel
Driver Override
System Off
ACC Proximity Warning
ACC Unavailable Warning
The instrument cluster display will return to the last
display selected after five seconds of no ACC

94STARTING AND OPERATING
When ACC Is Active

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 the vehicle in front. If your
vehicle follows the vehicle in front 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 uphill and downhill. However, a slight
speed change on moderate hills is normal.
In addition, downshifting may occur while
climbing uphill or descending downhill. This is
normal operation and necessary to maintain set
speed. When driving uphill and downhill, the
ACC system will cancel if the braking tempera -
ture 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 will show in the instrument cluster display.
Distance Settings

To adjust the distance setting, push the Distance
Setting Button and release. Each time the button is
pushed, the distance setting decreases by one bar
(longer). Once the longest setting is reached, if the
button is pushed again it will be set to the shortest
setting available.

If a slower moving vehicle is detected in the same lane,
the instrument cluster display will show the ACC Set
With Target Detected Light. The system will then adjust
vehicle speed automatically 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 Ú
page 92.
The maximum braking applied by ACC is limited;
however, 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 instrument cluster display
and a chime will sound while ACC continues to apply its
maximum braking force.

NOTE:The “BRAKE!” screen in the instrument cluster
display 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.

2 — Medium Distance Setting (Two Bars)
3 — Long Distance Setting (Three Bars)
4 — Short Distance Setting (One Bar)

23_VF_OM_EN_USC_t.book Page 94

STARTING AND OPERATING97
OFFSET DRIVING
ACC may not detect a vehicle in the same lane that
is offset from your direct line of travel, or a vehicle
merging in from a side lane. There may not be
sufficient distance to the vehicle ahead. The offset
vehicle may move in and out of the line of travel,
which can cause your vehicle to brake or
accelerate unexpectedly.

Offset Driving Condition Example

TURNS AND BENDS
When driving on a curve with ACC engaged, the
system may increase or decrease the vehicle
speed for stability, with no vehicle ahead detected.
Once the vehicle is out of the curve, the system will
resume your original set speed. This is a part of
normal ACC system functionality.
NOTE:On tight turns ACC performance may be limited.
USING ACC ON HILLS
ACC performance may be limited when driving on
hills. ACC may not detect a vehicle in your lane
depending on the speed, vehicle load, traffic
conditions, and the steepness of the hill.
ACC Hill Example

LANE CHANGING

ACC may not detect a vehicle until it is completely in
the lane in which you are traveling. In the following
lane changing example, ACC has not yet detected
the vehicle changing lanes and it may not detect the
vehicle until it's too late for the ACC system to take
action. ACC may not detect a vehicle until it is
completely in the lane. There may not be sufficient
distance to the lane-changing vehicle. Always be
attentive and ready to apply the brakes if necessary.Lane Changing Example
