When the System Does Not
Seem to Work Properly
The RVC system may not work
properly or display a clear image if:
. The RVC is turned off.
. It is dark.
. The sun or the beam of
headlamps is shining directly
into the camera lens.
. Ice, snow, mud, or anything else
builds up on the camera lens.
Clean the lens, rinse it with
water, and wipe it with a soft

. The back of the vehicle is in an
accident. The position and
mounting angle of the camera
can change or the camera, can
be affected. Be sure to have the
camera and its position and
mounting angle checked at your
dealer.
Parking Assist
If equipped, Rear Parking Assist
(RPA) assists the driver with parking
and avoiding objects while in
R (Reverse). RPA operates at
speeds less than 8 km/h (5 mph).
The sensors on the rear bumper
detect objects up to 1.5 m (4.9 ft)
behind the vehicle, and at least
20 cm (8 in) off the ground. The
distance at which objects can be
detected may be less during warmer
or humid weather.
{Warning
The parking assist system does
not detect children, pedestrians,
bicyclists, animals, or objects
below the bumper or that are too
close or too far from the vehicle.
It is not available at speeds
greater than 8 km/h (5 mph). To
prevent injury, death, or vehicle
damage, even with parking assist,
always check the area around the
vehicle and check all mirrors
before backing.

Driving and Operating 205
How the System Works
RPA comes on automatically when
the shift lever is moved into
R (Reverse). A single beep sounds
to indicate the system is working.
RPA operates only at speeds less
than 8 km/h (5 mph).
An obstacle is indicated by audible
beeps. The time between the beeps
becomes shorter as the vehicle gets
closer to the obstacle. When the
distance is less than 30 cm (12 in),
the beeping is a continuous tone.
Turning the System On and Off
The RPA system can be turned on
and off using the infotainment
system controls. SeeVehicle
Personalization 0129.
When the system is off, PARK
ASSIST OFF displays on the Driver
Information Center (DIC). The
message disappears after a short
period of time.
RPA defaults to the on setting each
time the vehicle is started.
When the System Does Not
Seem to Work Properly
The following messages may be
displayed on the DIC:
SERVICE PARKING ASSIST : If
this message occurs, check the
following conditions:
. The sensors are not clean. Keep
the vehicle's rear bumper free of
mud, dirt, snow, ice, and slush.
For cleaning instructions, see
Exterior Care 0283.
. The park assist sensors are
covered by frost or ice. Frost or
ice can form around and behind
the sensors and may not always
be seen; this can occur after
washing the vehicle in cold
weather. The message may not
clear until the frost or ice has
melted.
If the above conditions do not exist,
take the vehicle to your dealer to
repair the system. PARK ASSIST OFF :
If the RPA
system does not activate due to a
temporary condition, the message
displays on the DIC. This can occur
under the following conditions:
. The driver has disabled the
system.
. An object was hanging out of the
trunk during the last drive cycle.
Once the object is removed,
RPA will return to normal
operation.
. The bumper is damaged. Take
the vehicle to your dealer to
repair the system.
. Other conditions, such as
vibrations from a jackhammer or
the compression of air brakes on
a very large truck, are affecting
system performance.
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

Chevrolet Sonic Owner Manual (GMNA-Localizing-U.S./Canada-11373973) -
2018 - crc - 10/9/17
206 Driving and Operating
quickly, FCA provides a red flashing
alert on the windshield and rapidly
beeps.
FCA detects vehicles within a
distance of approximately 60 m
(197 ft) and operates at speeds
above 40 km/h (25 mph).
{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 Driving0171.
FCA can be disabled with the FCA
steering wheel control.
Detecting the Vehicle Ahead
FCA warnings will not occur unless
the FCA system detects a vehicle
ahead. When a vehicle is detected,
the vehicle ahead indicator will
display green. Vehicles may not be
detected on curves, highway exit
ramps, or hills, due to poor visibility;
or if a vehicle ahead is partially
blocked by pedestrians or other
objects. FCA will not detect another
vehicle ahead until it is completely
in the driving lane.
{Warning
FCA does not provide a warning
to help avoid a crash, unless it
detects a vehicle. FCA may not
detect a vehicle ahead if the FCA
sensor is blocked by dirt, snow, (Continued)
Warning (Continued)
or ice, or if the windshield is
damaged. It may also not detect a
vehicle on winding or hilly roads,
or in conditions that can limit
visibility such as fog, rain,
or snow, or if the headlamps or
windshield are not cleaned or in
proper condition. Keep the
windshield, headlamps, and FCA
sensors clean and in good repair.
Collision Alert
When your vehicle approaches
another detected vehicle too rapidly,
the red FCA display on top of the
instrument panel to the right of the
steering wheel will flash. Also,
several rapid high-pitched beeps will
sound from the front. When this

Chevrolet Sonic Owner Manual (GMNA-Localizing-U.S./Canada-11373973) -
2018 - crc - 10/9/17
Driving and Operating 207
Collision Alert occurs, the brake
system may prepare for driver
braking to occur more rapidly which
can cause a brief, mild deceleration.
Continue to apply the brake pedal
as needed. Cruise control may be
disengaged when the Collision Alert
occurs.
Tailgating Alert
The red FCA display will stay
continuously illuminated when you
are following a detected vehicle
ahead much too closely.
Selecting the Alert Timing
The Collision Alert control is on the
steering wheel. Press COLLISION
ALERT to set the alert timing to far,
medium, near or off. The first button
press shows the current control
setting on the DIC. Additional button
presses will change this setting. The
chosen setting will remain until it is
changed and will affect both the
Collision Alert and the Tailgating
Alert features. The timing of both
alerts will vary based on vehicle
speed. The faster the vehicle speed,
the farther away the alert will occur.Consider traffic and weather
conditions when selecting the alert
timing. The range of selectable alert
timing may not be appropriate for all
drivers and driving conditions.
Unnecessary Alerts
FCA may sometimes set
unnecessary alerts to turning
vehicles, vehicles in other lanes,
objects that are not vehicles,
or shadows. These alerts are
normal operation and the vehicle
does not need service.
Cleaning the System
If the FCA system does not seem to
operate properly, cleaning the
outside of the windshield in front of
the rearview mirror may correct the
issue.
Lane Departure
Warning (LDW)
If equipped, LDW may help avoid
crashes due to unintentional lane
departures. It may provide an alert if
the vehicle is crossing a lane
without using a turn signal in thatdirection. LDW uses a camera
sensor to detect the lane markings
at speeds of 56 km/h (35 mph) or
greater.
{Warning
The LDW system does not steer
the vehicle. The LDW system
may not:
. Provide enough time to
avoid a crash.
. Detect lane markings under
poor weather or visibility
conditions. This can occur if
the windshield or
headlamps are blocked by
dirt, snow, or ice; if they are
not in proper condition; or if
the sun shines directly into
the camera.
. Detect road edges.
. Detect lanes on winding or
hilly roads.
(Continued)

Chevrolet Sonic Owner Manual (GMNA-Localizing-U.S./Canada-11373973) -
2018 - crc - 10/9/17
208 Driving and Operating
Warning (Continued)
If LDW only detects lane
markings on one side of the road,
it will only warn you when
departing the lane on the side
where it has detected a lane
marking. Always keep your
attention on the road and
maintain proper vehicle position
within the lane, or vehicle
damage, injury, or death could
occur. Always keep the
windshield, headlamps, and
camera sensors clean and in
good repair. Do not use LDW in
bad weather conditions.
How the System Works
The LDW camera sensor is on the
windshield ahead of the rearview
mirror.
To turn LDW on and off, press
@on
the center console. The control
indicator will light when LDW is on. When LDW is on,
@is green if
LDW is available to warn of a lane
departure. If the vehicle crosses a
detected lane marking without using
the turn signal in that direction,
@
changes to amber and flashes.
Additionally, there will be three
beeps on the right or left, depending
on the lane departure direction.
When the System Does Not
Seem To Work Properly
The system may not detect lanes as
well when there are:
. Close vehicles ahead.
. Sudden lighting changes, such
as when driving through tunnels.
. Banked roads.
If the LDW system is not functioning
properly when lane markings are
clearly visible, cleaning the
windshield may help. LDW alerts may occur due to tar
marks, shadows, cracks in the road,
temporary or construction lane
markings, or other road
imperfections. This is normal system
operation; the vehicle does not need
service. Turn LDW off if these
conditions continue.

replaced and the vehicle is
equipped with a front camera sensor
for the Driver Assistance Systems, a
GM replacement windshield is
recommended. The replacement
windshield must be installed
according to GM specifications for
proper alignment. If it is not, these
systems may not work properly, they
may display messages, or they may
not work at all. See your dealer for
proper windshield replacement.
Gas Strut(s)
This vehicle is equipped with gas
strut(s) to provide assistance in
lifting and holding open the hood/
trunk/liftgate system in full open
position.
{Warning
If the gas struts that hold open
the hood, trunk, and/or liftgate fail,
you or others could be seriously
injured. Take the vehicle to your
dealer for service immediately.
Visually inspect the gas struts for
signs of wear, cracks, or other
damage periodically. Check to
make sure the hood/trunk/liftgate
is held open with enough force.
If struts are failing to hold the
hood/trunk/liftgate, do not
operate. Have the vehicle
serviced.
Caution
Do not apply tape or hang any
objects from gas struts. Also do
not push down or pull on gas
struts. This may cause damage to
the vehicle.
