DRIVING AND OPERATING 221
When pressed, the current gap setting
displays briefly on the instrument
cluster and HUD, if equipped.
Subsequent presses cycle the gap
button through three settings: Far,
Medium, or Near. The gap setting will
be maintained until it is changed.
Since each gap setting corresponds to
a following time (Far, Medium,
or Near), the following distance will
vary based on vehicle speed. The
faster the vehicle speed, the further
back your vehicle will follow a vehicle
detected ahead. Consider traffic and
weather conditions when selecting the
following gap. The range of selectable
gaps may not be appropriate for all
drivers and driving conditions.
Changing the gap setting
automatically changes the alert timing
sensitivity (Far, Medium, or Near) for
the Forward Collision Alert (FCA)
feature. SeeForward Collision Alert
(FCA) System 0232. Alerting the Driver
Without Head-Up Display
With Head-Up Display
If ACC is engaged, driver action may
be required when ACC cannot apply
sufficient braking because of
approaching a vehicle too rapidly.
When this condition occurs, a series
of red lights or the collision alert
symbol on the HUD, if equipped, will
flash on the windshield. Either eight
beeps will sound from the front,
or both sides of the Safety Alert Seat
will pulse five times. See “Collision/
Detection Systems” underVehicle
Personalization 0144. See
Defensive Driving 0178.
Approaching and Following a
Vehicle
The vehicle ahead indicator is in the
instrument cluster and HUD display,
if equipped.
The vehicle ahead indicator only
displays when a vehicle is detected in
your vehicle’s path moving in the
same direction.
If this indicator is not displaying, ACC
will not respond to or brake to
vehicles ahead.
ACC automatically slows the vehicle
down and adjusts vehicle speed to
follow the vehicle in front at the
selected follow gap. The vehicle speed
increases or decreases to follow the
vehicle in front of you, but will not
exceed the set speed. It may apply
limited braking, if necessary. When

is maneuvering the vehicle into a
previously detected space. The APA
system does not need service.
APA will instruct the vehicle to stop
once a large enough space is found.
Follow the displayed instructions.
When instructed to drive in reverse,
shift to R (Reverse) to engage
automatic steering. The steering wheel
will briefly vibrate as a reminder to
remove hands from the steering
wheel. Check surroundings and
continue braking or accelerating as
needed, and be prepared to stop to
avoid vehicles, pedestrians, or objects.
If the vehicle exceeds 10 km/h
(6 mph), APA is automatically
disengaged and automatic steering
will turn off. A progress arrow displaysthe status of the parking maneuver.
Depending on the space size,
additional maneuvers may be
required, and there will be additional
instructions. When changing gears,
allow the automatic steering to
complete before continuing the
parking maneuver. Upon successful
completion of a maneuver, APA will
beep and display a PARKING
COMPLETE message. Place the vehicle
in P (Park).
APA may automatically disengage if:
.
The steering wheel is used by the
driver.
. The maximum allowed speed is
exceeded.
. There is a failure with the APA
system.
. Electronic stability control or
antilock brakes are activated.
. A high priority vehicle message is
displayed in the DIC.
To cancel APA, press
Oagain. When the System Does Not Seem to
Work Properly
The APA system may require a short
period of driving along curves to
calibrate.
Assistance Systems for
Driving
If equipped, when driving the vehicle
in a forward gear, Forward Collision
Alert (FCA), Lane Departure Warning
(LDW), Lane Keep Assist (LKA), Side
Blind Zone Alert (SBZA), Lane Change
Alert (LCA), and/or Forward
Automatic Braking (FAB) can help to
avoid a crash or reduce crash damage.
Forward Collision Alert
(FCA) System
If equipped, the FCA system may help
to avoid or reduce the harm caused by
front-end crashes. When approaching
a vehicle ahead too quickly, FCA
provides a flashing red alert on the
windshield and rapidly beeps or pulses
the Safety Alert Seat. FCA also lights
an amber visual alert if following
another vehicle much too closely.

display will light up in the
corresponding outside side mirror and
will flash if the turn signal is on.
{Warning
LCA does not alert the driver to
vehicles outside of the system
detection zones, pedestrians,
bicyclists, or animals. It may not
provide alerts when changing lanes
under all driving conditions. Failure
to use proper care when changing
lanes may result in injury, death,
or vehicle damage. Before making a
lane change, always check mirrors,
glance over your shoulder, and use
the turn signals.LCA Detection Zones
1. SBZA Detection Zone
2. LCA Detection Zone
The LCA sensor covers a zone of
approximately one lane over from
both sides of the vehicle, or 3.5 m
(11 ft). The height of the zone is
approximately between 0.5 m (1.5 ft)
and 2 m (6 ft) off the ground. The Side
Blind Zone Alert (SBZA) warning area
starts at approximately the middle of
the vehicle and goes back 5 m (16 ft).
Drivers are also warned of vehicles
rapidly approaching from up to 25 m
(82 ft) behind the vehicle.
How the System Works
The LCA symbol lights up in the side
mirrors when the system detects a
moving vehicle in the next lane over
that is in the side blind zone or
rapidly approaching that zone from
behind. A lit LCA symbol indicates it
may be unsafe to change lanes. Before
making a lane change, check the LCA
display, check mirrors, glance over
your shoulder, and use the turn
signals.

When the vehicle is started, both
outside mirror LCA displays will
briefly come on to indicate the system
is operating. When the vehicle is in a
forward gear, the left or right side
mirror display will light up if a moving
vehicle is detected in the next lane
over in that blind zone or rapidly
approaching that zone. If the turn
