If equipped, when driving the
vehicle forward, Forward Collision
Alert (FCA), Lane Departure
Warning (LDW), Lane Change Alert
(LCA), and/or the Active Emergency
Braking System can help to avoid a
crash or reduce crash damage.
Forward Collision Alert
(FCA) System
The FCA system may help to avoid
or reduce the harm caused by
front-end crashes. FCA provides a
flashing red alert on the windshield,
and beeps or pulses the Safety Alert
Seat when approaching a vehicle
directly ahead too quickly. FCA also
provides a visual alert if following
another vehicle much too closely.
FCA detects vehicles within a
distance of approximately 60 m
(197 ft) and operates at speeds
above 40 km/h (25 mph). If the
vehicle has Adaptive Cruise Control (ACC), it can detect vehicles to
distances of approximately 110 m
(360 ft). See
Adaptive Cruise
Control on page 9-39.
{Warning
FCA is a warning system and
does not apply the brakes. When
approaching a slower-moving or
stopped vehicle ahead too rapidly,
or when following a vehicle too
closely, FCA may not provide a
warning with enough time to help
avoid a crash. FCA does not warn
of pedestrians, animals, signs,
guardrails, bridges, construction
barrels, or other objects. Be ready
to take action and apply the
brakes. For more information, see
Defensive Driving on page 9-3.
FCA can be disabled through
vehicle personalization. See the
“Auto Collision Preparation” portion

{Warning
Using the Automatic Collision
Preparation System while towing
a trailer could cause you to lose
control of the vehicle and crash.
Turn the system off when towing
a trailer.
Side Blind Zone
Alert (SBZA)
If equipped, the SBZA system is a
lane-changing aid that assists
drivers with avoiding crashes that
occur with vehicles in the side blind
zone (or spot) areas. When the
vehicle is moving forward, the left-
or right-side mirror display will light
up if a vehicle is detected in that
blind zone. If the turn signal is
activated and a vehicle is also
detected on the same side, the
display will flash as an extra
warning not to change lanes. Since
this system is part of the LaneChange Alert system, please read
the entire Lane Change Alert
section before using this feature.
Lane Change Alert
If equipped, the LCA system is a
lane-changing aid that assists
drivers with avoiding lane change
crashes that occur with vehicles in
the side blind zone (or spot) areas
or with vehicles rapidly approaching
these areas from behind. The LCA
warning 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
(Continued)
Warning (Continued)
injury, death, or vehicle damage.
Before making a lane change,
always check mirrors, glance over
your shoulder, and use the turn
signals.

(11 ft). The height of the zone is
approximately between 0.5 m (1.5 ft)
