20 In Brief
FPB provides a red flashing alert on
the windshield and rapidly beeps or
pulses the driver seat. FPB can
provide a boost to braking or
automatically brake the vehicle.
SeeFront Pedestrian Braking (FPB)
System 0211.
Lane Keep Assist (LKA)
If equipped, LKA may help avoid
crashes due to unintentional lane
departures. It may assist by gently
turning the steering wheel if the
vehicle approaches a detected lane
marking without using a turn signal
in that direction. It may also provide
a Lane Departure Warning (LDW)
alert as the lane marking is crossed.
The system will not assist or alert if
it detects that you are actively
steering. Override LKA by turning
the steering wheel. LKA uses a
camera to detect lane markings
between 60 km/h (37 mph) and
180 km/h (112 mph).
See Lane Departure Warning (LDW)
0 215 andLane Keep Assist (LKA)
0 216.
Lane Change Alert (LCA)
If equipped, the LCA system is a
lane-changing aid that assists
drivers with avoiding lane change
crashes that occur with moving
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 mirror and will flash if the
turn signal is on. The Side Blind
Zone Alert (SBZA) system is
included as part of the LCA system.
See Side Blind Zone Alert (SBZA)
0 213 andLane Change Alert (LCA)
0 214.
Rear Vision
Camera (RVC)
RVC displays a view of the area
behind the vehicle on the
infotainment display when the
vehicle is shifted into R (Reverse) to
aid with parking and low-speed
backing maneuvers.
See Assistance Systems for Parking
or Backing 0204.
Rear Cross Traffic Alert
(RCTA) System
If equipped, the RCTA system uses
a triangle with an arrow displayed
on the infotainment display to warn
of traffic behind your vehicle that
may cross your vehicle's path while
in R (Reverse). In addition, beeps
will sound, or the driver seat will
pulse.
See Assistance Systems for Parking
or Backing 0204.
Parking Assist
If equipped, Rear Parking
Assist (RPA) uses sensors on the
rear bumper to assist with parking
and avoiding objects while in
R (Reverse). It operates at speeds
less than 8 km/h (5 mph). RPA may
display a warning triangle on the
infotainment display and a graphic
on the instrument cluster to provide
the object distance. In addition,
multiple beeps or seat pulses may
occur if very close to an object.
See Assistance Systems for Parking
or Backing 0204.

unique seat positions for driving the
vehicle, and a shared exit position
for getting out of the vehicle. Other
feature positions may also be set,
such as power mirrors and power
steering wheel, if equipped. Memory positions are linked to RKE
transmitter 1 or 2 for automatic
memory recalls.
Before storing, adjust all available
memory feature positions. Turn the
ignition on and then press and
release SET; a beep will sound.
Then immediately press and hold 1,

Obstructions
If something has blocked the driver
seat and/or power steering wheel
while recalling a memory position,
the recall may stop. Remove the
obstruction and try the recall again.
If the memory position still does not
recall, see your dealer for service.
Heated and Ventilated
Front Seats
{Warning
If temperature change or pain to
the skin cannot be felt, the seat
heater may cause burns. To
reduce the risk of burns, use care
when using the seat heater,
especially for long periods of
time. Do not place anything on
the seat that insulates against
heat, such as a blanket, cushion,
cover, or similar item. This may
cause the seat heater to
overheat. An overheated seat
heater may cause a burn or may
damage the seat.
Heated and Ventilated Seat
Buttons Shown, Heated Seat Buttons Similar

highest setting. With each press of
the button, the seat will change to
the next lower setting, and then to
the off setting. The lights near the
heated or ventilated seat symbol on
the button indicate three for the

{Warning
Stowing articles under the
passenger seat or between the
passenger seat cushion and
seatback may interfere with the
proper operation of the passenger
sensing system.
Servicing the
Airbag-Equipped Vehicle
Airbags affect how the vehicle
should be serviced. There are parts
of the airbag system in several
places around the vehicle. Your
dealer and the service manual have
information about servicing the
vehicle and the airbag system. To
purchase a service manual, see
Service Publications Ordering
Information0334.
{Warning
For up to 10 seconds after the
vehicle is turned off and the 12‐
volt battery is disconnected, an
airbag can still inflate during
improper service. You can be
injured if you are close to an
airbag when it inflates. Avoid
yellow connectors. They are
probably part of the airbag
system. Be sure to follow proper
service procedures, and make
sure the person performing work
for you is qualified to do so.
Adding Equipment to the
Airbag-Equipped Vehicle
Adding accessories that change the
vehicle's frame, bumper system,
height, front end, or side sheet
metal may keep the airbag system
from working properly. The
operation of the airbag system can
also be affected by changing any
parts of the front seats, seat belts,
airbag sensing and diagnostic
module, steering wheel, instrument panel, inner door seals including the
speakers, any of the airbag
modules, ceiling or pillar garnish
trim, overhead console, front
sensors, side impact sensors,
or airbag wiring.
Your dealer and the service manual
have information about the location
of the airbag sensors, sensing and
diagnostic module, and airbag
wiring.
In addition, the vehicle has a
passenger sensing system for the
front outboard passenger position,
which includes sensors that are part
of the passenger seat. The
passenger sensing system may not
operate properly if the original seat
trim is replaced with non-GM
covers, upholstery, or trim; or with
GM covers, upholstery, or trim
designed for a different vehicle. Any
object, such as an aftermarket seat
heater or a comfort-enhancing pad
or device, installed under or on top
of the seat fabric, could also
interfere with the operation of the
passenger sensing system. This
could either prevent proper
deployment of the passenger
