Parking Assist
With RPA, and if equipped with FPA,as the vehicle moves at speeds ofless than 8 km/h (5 mph) thesensors on the bumpers may detectobjects up to 2.5 m (8 ft) behind and1.2 m (4 ft) in front of the vehiclewithin a zone 25 cm (10 in) high offthe ground and below bumper level.These detection distances may beshorter during warmer or humidweather. Blocked sensors will notdetect objects and can also causefalse detections. Keep the sensorsclean of mud, dirt, snow, ice, andslush; and clean sensors after a carwash in freezing temperatures.
{Warning
The Parking Assist system does
not detect children, pedestrians,
bicyclists, animals, or objects
located 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 moving
forward or backing.
The instrument cluster may have aparking assist display with bars thatshow“distance to object”and objectlocation information for the ParkingAssist system. As the object getscloser, more bars light up and thebars change color from yellow toamber to red.
When an object is first detected inthe rear, one beep will be heardfrom the rear, or both sides of theSafety Alert Seat will pulse twotimes. When an object is very close(<0.6 m (2 ft) in the vehicle rear,or <0.3 m (1 ft) in the vehicle front),acontinuousbeepwillsoundfromthe front or rear, or both sides of theSafety Alert Seat will pulse fivetimes. Beeps for FPA are higherpitched than for RPA.

{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,
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 approachesanother detected vehicle too rapidly,the red FCA display will flash on thewindshield. Also, eight rapidhigh-pitched beeps will sound fromthe front, or both sides of the SafetyAlert Seat will pulse five times.When this Collision Alert occurs, thebrake system may prepare for driverbraking to occur more rapidly whichcan cause a brief, mild deceleration.Continue to apply the brake pedalas needed. Cruise control may bedisengaged when the Collision Alertoccurs.
Tailgating Alert
The vehicle ahead indicator willdisplay amber when you arefollowing a detected vehicle aheadmuch too closely.

Lane Departure Warning
(LDW) (2500/3500 Series)
If equipped, LDW may help avoidcrashes due to unintentional lanedepartures. It may provide an alert ifthe vehicle is crossing a lane
Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-9956065) - 2017 - CRC - 4/29/16
308 Driving and Operating
marking without using a turn signalin that direction. LDW uses acamera sensor to detect the lanemarkings 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 toavoid a crash.
.Detect lane markings underpoor weather or visibilityconditions. This can occur ifthe windshield orheadlamps are blocked bydirt, snow, or ice; if they arenot in proper condition; or ifthe sun shines directly intothe camera.
.Detect road edges.
.Detect lanes on winding orhilly roads.
(Continued)
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

When the System Does Not
Seem to Work Properly
The system may not detect lanes aswell when there are:
.Close vehicles ahead.
.Sudden lighting changes, suchas when driving through tunnels.
.Banked roads.

Driving and Operating 309
If the LDW system is not functioningproperly when lane markings areclearly visible, cleaning thewindshield may help.
LDW alerts may occur due to tarmarks, shadows, cracks in the road,temporary or construction lanemarkings, or other roadimperfections. This is normal systemoperation; the vehicle does not needservice. Turn LDW off if theseconditions continue.
Lane Keep Assist (LKA)
(1500 Series)
If equipped, LKA may help avoidcrashes due to unintentional lanedepartures. It may assist by gentlyturning the steering wheel if thevehicle approaches a detected lanemarking without using a turn signalin that direction. It may also provideaLaneDepartureWarning(LDW)system alert as the lane marking iscrossed. The LKA system will notassist or provide an LDW alert if itdetects that you are activelysteering. Override LKA by turningthe steering wheel. LKA uses a
camera to detect lane markingsbetween 60 km/h (37 mph) and180 km/h (112 mph).
{Warning
The LKA system does not
continuously steer the vehicle.
It may not keep the vehicle in the
lane or give a Lane Departure
Warning (LDW) alert, even if a
lane marking is detected.
The LKA and LDW systems
may not:
.Provide an alert or enoughsteering assist to avoid alane departure or crash.
.Detect lane markings underpoor weather or visibilityconditions. This can occur ifthe windshield orheadlamps are blocked bydirt, snow, or ice, if they arenot in proper condition, or ifthe sun shines directly intothe camera.
.Detect road edges.
(Continued)
Warning (Continued)
.Detect lanes on winding orhilly roads.
If LKA only detects lane markings
on one side of the road, it will
only assist or provide an LDW
alert when approaching the lane
on the side where it has detected
alanemarking.EvenwithLKA
and LDW, you must steer the
vehicle. 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 LKA in
bad weather conditions.

Integrated Trailer Brake
Control System
The vehicle may have an IntegratedTrailer Brake Control (ITBC) systemfor use with electric trailer brakes ormost electric over hydraulic trailerbrakes.
This symbol is on the Trailer BrakeControl Panel on vehicles with anITBC system. The power output tothe trailer brakes is based on theamount of brake pressure beingapplied by the vehicle’sbrake
system, and on the type of trailerbrakes detected. This availablepower output to the trailer brakescan be adjusted to a wide range oftrailering situations.
The ITBC system is integrated withthe vehicle’sbrake,antilockbrake,and StabiliTrak systems. In traileringconditions that cause the vehicle’santilock brake or StabiliTraksystems to activate, power sent tothe trailer's brakes will beautomatically adjusted to minimizetrailer wheel lock-up. This does notimply that the trailer has StabiliTrak.
If the vehicle’sbrake,antilockbrake,or StabiliTrak systems are notfunctioning properly, the ITBCsystem may not be fully functionalor may not function at all. Make sureall of these systems are fullyoperational to ensure fullfunctionality of the ITBC system.
The ITBC system is poweredthrough the vehicle's electricalsystem. Turning the ignition off willalso turn off the ITBC system. TheITBC system is fully functional onlywhen the ignition is in ON/RUN.
{Warning
Connecting a trailer that has an
air brake system may result in
reduced or complete loss of trailer
braking. There may be an
increase in stopping distance or
trailer instability which could
result in personal injury or
damage to the vehicle, trailer,
or other property. Use the ITBC
system only with electric or
electric over hydraulic trailer
brakes.

Manual Trailer Brake Apply
The Manual Trailer Brake ApplyLever is used to apply the trailer’selectric brakes independent of thevehicle’sbrakes.Slidingthelevertothe left will apply only the trailerbrakes. Use this lever to adjustTrailer Gain to properly adjust thepower output to the trailer brakes.
The trailer's and the vehicle's brakelamps will come on when eithervehicle brakes or manual trailerbrakes are applied.
Trailer Gain Adjustment Procedure
Trailer Gain should be set for aspecific trailering condition and mustbe adjusted anytime vehicle loading,trailer loading, or road surfaceconditions change.
{Warning
Trailer brakes that are
over-gained or under-gained may
not stop the vehicle and the trailer
as intended and can result in a
crash. Always follow the
instructions to set the Trailer Gain
for the proper trailer stopping
performance.
Use the following to adjust TrailerGain for each towing condition:
1. Drive the vehicle with the trailerattached on a level roadsurface representative of thetowing condition and free oftraffic at about 32 to 40 km/h(20 to 25 mph) and fully applythe Manual Trailer Brake ApplyLever.
Adjusting Trailer Gain atspeeds lower than 32 to40 km/h (20 to 25 mph) mayresult in an incorrect gainsetting.
2. Adjust the Trailer Gain, usingthe Trailer Gain AdjustmentButtons, to just below the pointof trailer wheel lock-up,indicated by trailer wheelsqueal or tire smoke when atrailer wheel locks.
Trailer wheel lock-up may notoccur if towing a heavily loadedtrailer. In this case, adjust theTrailer Gain to the highestallowable setting for the towingcondition.
3. Readjust Trailer Gain anytimevehicle loading, trailer loading,or road surface conditionschange or if trailer wheellock-up is noticed at any timewhile towing.

damaged if either the front or rear
axle ratings or the Gross Vehicle
Weight Rating (GVWR) are
exceeded.
The plow the vehicle can carrydepends on many things, such as:
.The options the vehicle camewith, and the weight of thoseoptions.
.The weight and number ofpassengers to be carried.
.The weight of items added to thevehicle, like a tool box ortruck cap.
.The total weight of anyadditional cargo to be carried.
For example, if the snow plowweighs 318 kg (700 lb), the totalweight of all occupants and cargoinside the cab should not exceed135 kg (300 lb). This means that youmay only be able to carry onepassenger. Even this may be too
much if there is other equipmentalready adding to the weight of thevehicle.
To s a f e l y c a r r y a s n o w p l o w o n t h evehicle:
.Follow all aftermarket snow plowmanufacturer’sinstructionsforthe operation and transportationof the snow plow.
.With a snow plow attached, theengine coolant temperaturegauge may show a highertemperature than while drivingwithout one. The snow plowcould block the airflow to theradiator. This could be morenoticeable as vehicle speedincreases. At speeds above72 km (45 mph), this may causethe engine coolant to overheat.
.To i n c r e a s e t h e a i r f l o w, m o v e t h esnow plow blade postion.
.If driving more than 24 km(15 mi), angle the plow bladeposition.
.Make sure the weight on thefront and rear axles does notexceed the axle rating for each.
.For the front axle, if more cargoor passengers must be carried,appropriate counter ballast mustbe installed rear of the rear axle.Counter ballast must be properlysecured so it will not moveduring driving.
.Rear ballast may be required toensure a proper front and rearweight distribution ratio, eventhough the actual weight at thefront axle may be less than thefront axle rating.
.The snow plow manufacturer orinstaller can assist indetermining the amount of rearballast required, to help makesure the snow plow/vehiclecombination does not exceedthe GVW rating, the front andrear axle ratings, and the frontand rear weight distribution ratio.
.The total vehicle must notexceed the GVW rating.
