170 CLIMATE CONTROLS
Remote Start Climate Control
Operation :If equipped with the
remote start feature, the climate
control system may run when the
vehicle is started remotely. The system
will use the defrost setting if it is cold
outside or turn on using the coldest
setting if it is hot outside. The rear
defog may come on during remote
start based on cold ambient
conditions. The rear defog indicator
light does not come on during a
remote start.
If equipped, the heated seats will turn
on if it is cold outside or the
ventilated seats will turn on if it is hot
outside. The heated and ventilated
seat indicator lights may not come on
during a remote start. If equipped, the
heated steering wheel will come on in
a remote start if it is cold outside. The
heated steering wheel indicator light
may not come on. See Remote Vehicle
Start 036 and Heated and Ventilated
Front Seats 069.Sensor
The solar sensor, on top of the
instrument panel near the windshield,
monitors the solar intensity.
The climate control system uses the
sensor information to adjust the
temperature, fan speed, recirculation,
and air delivery mode for best
comfort.
If the sensor is covered, the automatic
climate control system may not work
properly.
Air Vents
Adjustable air vents are in the center
and on the sides of the instrument
panel, and on the rear of the center
console storage.
Move the slider knobs to change the
direction of or to close off the airf low.

the first detent. For each press, the
vehicle goes about 1 km/h (1 mph)
slower.
. To decrease the vehicle speed in
larger increments, move the
thumbwheel down toward SET− to
the second detent. For each press,
the vehicle speed decreases to the
next 5 km/h (5 mph) mark on the
speedometer.
. To decrease speed while the
vehicle is stopped, move the
thumbwheel down toward SET−
until the desired set speed is
displayed.
The speedometer reading can be
displayed in either English or metric
units. See Instrument Cluster 0126.
The increment value used depends on
the units displayed.
Selecting the Follow Distance Gap
When a slower moving vehicle is
detected ahead within the selected
following gap, ACC will adjust the
vehicle's speed and attempt to
maintain the follow distance gap
selected. Press[on the steering wheel to
adjust the following gap. Each press
cycles the gap button through three
settings: Far, Medium, or Near.
When pressed, the current gap setting
displays briefly on the instrument
cluster and HUD. 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. See Forward Collision Alert
(FCA) System 0226. Alerting the Driver
With Head-Up Display
Without 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, six 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
0 149.

226 DRIVING AND OPERATING
The brake holds the vehicle until the
parking brake or brake is applied,
or the vehicle is shifted into P (Park).
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), Forward Automatic
Braking (FAB), and/or the Front
Pedestrian Braking (FPB) System 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 red flashing alert on the
windshield and rapidly beeps or pulses
the driver seat. FCA also lights an
amber 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 8 km/h
(5 mph). If the vehicle has Adaptive
Cruise Control (ACC), it can detect
vehicles to distances of approximately
110 m (360 ft) and operates at all
speeds. See Adaptive Cruise Control
0 209.
{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. It also may not
provide any warning at all. FCA
does not warn of pedestrians,
animals, signs, guardrails, bridges,
construction barrels, or other
objects. Be ready to take action and
apply the brakes. See Defensive
Driving 0174.
FCA can be disabled. See “Collision/
Detection Systems” underVehicle
Personalization 0149.

DRIVING AND OPERATING 233
{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.
Left Side Mirror DisplayRight Side Mirror Display
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
signal is activated in the same
direction as a detected vehicle, this
display will flash as an extra warning
not to change lanes.
LCA is disabled when the trailer
connection status is displayed. A DIC
message may display. The SBZA
system still operates.
