{Warning
Coasting downhill in N (Neutral)
or with the ignition off is
dangerous. This can cause
overheating of the brakes and
loss of steering. Always have the
engine running and the vehicle
in gear.
.Drive at speeds that keep thevehicle in its own lane. Do notswing wide or cross thecenter line.
.Be alert on top of hills;something could be in your lane(e.g., stalled car, accident).
.Pay attention to special roadsigns (e.g., falling rocks area,winding roads, long grades,passing or no-passing zones)and take appropriate action.
Winter Driving
Driving on Snow or Ice
Snow or ice between the tires andthe road creates less traction orgrip, so drive carefully. Wet ice canoccur at about 0 °C (32 °F) whenfreezing rain begins to fall. Avoiddriving on wet ice or in freezing rainuntil roads can be treated.
For Slippery Road Driving:
.Accelerate gently. Acceleratingtoo quickly causes the wheels tospin and makes the surfaceunder the tires slick.
.Turn on Traction Control. SeeTr a c t i o n C o n t r o l / E l e c t r o n i cStability Control0295.
.The Antilock Brake System(ABS) improves vehicle stabilityduring hard stops, but thebrakes should be applied soonerthan when on dry pavement.SeeAntilock Brake System(ABS)0292.
.Allow greater following distanceand watch for slippery spots. Icypatches can occur on otherwiseclear roads in shaded areas.The surface of a curve or anoverpass can remain icy whenthe surrounding roads are clear.Avoid sudden steeringmaneuvers and braking whileon ice.
.Turn off cruise control.
Blizzard Conditions
Stop the vehicle in a safe place andsignal for help. Stay with the vehicleunless there is help nearby.If possible, use RoadsideAssistance. SeeRoadsideAssistance Program0476.Togethelp and keep everyone in thevehicle safe:
.Turn on the hazard warningflashers.
.Tie a red cloth to an outsidemirror.

Assistance Systems for
Driving
If equipped, when driving thevehicle in a forward gear, ForwardCollision Alert (FCA), LaneDeparture Warning (LDW), and/or
Lane Keep Assist (LKA) can help toavoid a crash or reduce crashdamage.
Forward Collision Alert
(FCA) System
If equipped, the FCA system mayhelp to avoid or reduce the harmcaused by front-end crashes. Whenapproaching a vehicle ahead tooquickly, FCA provides a red flashingalert on the windshield and rapidlybeeps or pulses the driver seat.FCA also lights an amber visualalert if following another vehiclemuch too closely.
FCA detects vehicles within adistance of approximately 60 m(197 ft) and operates at speedsabove 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,
(Continued)
Warning (Continued)
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 Driving0248.
FCA can be disabled with the FCAsteering wheel control.
Detecting the Vehicle Ahead
FCA warnings will not occur unlessthe FCA system detects a vehicleahead. When a vehicle is detected,the vehicle ahead indicator will

or Off. The first button press showsthe current setting on the DIC.Additional button presses willchange this setting. The chosensetting will remain until it is changedand will affect the timing of both theCollision Alert and the TailgatingAlert features. The timing of bothalerts will vary based on vehiclespeed. The faster the vehicle speed,the farther away the alert will occur.Consider traffic and weatherconditions when selecting the alerttiming. The range of selectable alerttiming may not be appropriate for alldrivers and driving conditions.
Unnecessary Alerts
FCA may provide unnecessaryalerts for turning vehicles, vehiclesin other lanes, objects that are notvehicles, or shadows. These alertsare normal operation and thevehicle does not need service.
Cleaning the System
If the FCA system does not seem tooperate properly, cleaning theoutside of the windshield in front ofthe rearview mirror, and cleaning the
front of the vehicle where radarsensors are located, may correctthe issue.
Forward Automatic
Braking (FAB)
If the vehicle has Forward CollisionAlert (FCA), it also has FAB, whichincludes Intelligent BrakeAssist (IBA). When the systemdetects a vehicle ahead in your paththat is traveling in the samedirection that you may be about tocrash into, it can provide a boost tobraking or automatically brake thevehicle. This can help avoid orlessen the severity of crashes whendriving in a forward gear. Dependingon the situation, the vehicle mayautomatically brake moderately orhard. This forward automaticbraking can only occur if a vehicle isdetected. This is shown by the FCAvehicle ahead indicator being lit.SeeForward Collision Alert (FCA)System0304.
The system works when driving in aforward gear between 8 km/h(5 mph) and 80 km/h (37 mph).It can detect vehicles up toapproximately 60 m (197 ft).

preparation feature and is not
designed to avoid crashes. Do
not rely on FAB to brake the
vehicle. FAB will not brake
outside of its operating speed
range and only responds to
detected vehicles.
FA B m a y n o t :
.Detect a vehicle ahead onwinding or hilly roads.
.Detect all vehicles,especially vehicles with atrailer, tractors, muddyvehicles, etc.
.Detect a vehicle whenweather limits visibility, suchas in fog, rain, or snow.

{Warning
Using FAB or IBA while towing a
trailer could cause you to lose
control of the vehicle and crash.
Turn the system to Alert or Off
when towing a trailer.
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
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.

How the System Works
The LKA camera sensor is on thewindshield ahead of the rearviewmirror.
To t u r n L K A o n a n d o f f , p r e s sA
on the center stack.
When on,Ais green if LKA is
available to assist and provide LDWalerts. It may assist by gentlyturning the steering wheel and
displayAas amber if the vehicle
approaches a detected lane markingwithout using a turn signal in thatdirection. It may also provide an
LDW alert by flashingAamber
as the lane marking is crossed.Additionally, there will be threebeeps, or the driver seat will pulse
three times, on the right or left,depending on the lane departuredirection.
The LKA system does notcontinuously steer the vehicle.If LKA does not detect active driversteering, an alert and chime may beprovided. Move the steering wheelto dismiss.
When the System Does Not
Seem to Work Properly
The system performance may beaffected by:
.Close vehicles ahead.
.Sudden lighting changes, suchas when driving through tunnels.
.Banked roads.
.Roads with poor lane markings,such as two-lane roads.
If the LKA system is not functioningproperly when lane markings areclearly visible, cleaning thewindshield may help.
LKA assistance and/or LDW alertsmay occur due to tar marks,shadows, cracks in the road,temporary or construction lanemarkings, or other roadimperfections. This is normal systemoperation; the vehicle does not needservice. Turn LKA off if theseconditions continue.
