{Warning
Using LKA while towing a trailer
or on slippery roads could cause
loss of control of the vehicle and
acrash.Turnthesystemoff.
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.

When towing a trailer:
.Become familiar with the stateand local laws that apply totrailer towing.

Chevrolet Silverado Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-9956065) - 2017 - CRC - 4/29/16
316 Driving and Operating
.The trailer must be equippedwith brakes adequate for theintended use. A loaded trailerweighing more than 900 kg(2,000 lb) must be equipped withits own brake system, withbrakes working on all axles.Trailer braking equipmentconforming to CanadianStandards Association (CSA)requirement CAN3-D313, or itsequivalent, is recommended.
.Do not tow a trailer during thefirst 800 km (500 mi) to preventdamage to the engine, axle,or other parts.
.Then during the first 800 km(500 mi) of trailer towing, do notdrive over 80 km/h (50 mph) anddo not make starts at full throttle.
.Vehicles can tow in D (Drive).The Tow/Haul Mode may beused if the transmission shiftstoo often. SeeTo w / H a u lMode0282.
.Turn off Park Assist whentowing.
{Warning
When towing a trailer, exhaust
gases may collect at the rear of
the vehicle and enter if the
liftgate, trunk/hatch, or rear-most
window is open.
When towing a trailer:
.Do not drive with theliftgate, trunk/hatch,or rear-most window open.
.Fully open the air outlets onor under the instrumentpanel.
.Also adjust the climatecontrol system to a settingthat brings in only outsideair. See“Climate ControlSystems”in the Index.

To w i n g a t r a i l e r r e q u i r e s a c e r t a i namount of experience. Thecombination you are driving islonger and not as responsive as the
vehicle itself. Get acquainted withthe handling and braking of the rigbefore setting out for the open road.
The structure, tires, and brakes ofthe trailer must be rated to carry theload. Inadequate trailer equipmentcan cause the combination tooperate in an unexpected or unsafemanner.
Before starting, check all trailer hitchparts and attachments, safetychains, electrical connectors, lamps,tires, and mirrors. Get familiar withthe handling and braking of the rig.If the trailer has electric brakes, startthe combination moving and thenapply the trailer brake controller byhand to be sure the brakes work.
During the trip, check occasionallyto be sure that the load is secureand the lamps and any trailerbrakes still work.
Following Distance
Stay at least twice as far behind thevehicle ahead as you would whendriving the vehicle without a trailer.This can help to avoid heavybraking and sudden turns.

Driving and Operating 317
Passing
More passing distance is neededwhen towing a trailer. Thecombination will not accelerate asquickly and is longer so it isnecessary to go much fartherbeyond the passed vehicle beforereturning to the lane.
Backing Up
Hold the bottom of the steeringwheel with one hand. To move thetrailer to the left, move that hand tothe left. To move the trailer to theright, move your hand to the right.Always back up slowly and,if possible, have someoneguide you.
Making Turns
Caution
Making very sharp turns while
trailering could cause the trailer to
come in contact with the vehicle.
The vehicle could be damaged.
Avoid making very sharp turns
while trailering.
When turning with a trailer, makewider turns than normal. Do this sothe trailer will not strike softshoulders, curbs, road signs, trees,or other objects. Avoid jerky orsudden maneuvers. Signal well inadvance.
If the trailer turn signal bulbs burnout, the arrows on the instrumentcluster will still flash for turns. It isimportant to check occasionally tobe sure the trailer bulbs are stillworking.
Driving on Grades
Reduce speed and shift to a lowergearbeforestarting down a long orsteep downgrade. If thetransmission is not shifted down, thebrakes might get hot and no longerwork well.
Vehicles can tow in D (Drive). Shiftthe transmission to a lower gear ifthe transmission shifts too oftenunder heavy loads and/or hillyconditions.
The Tow/Haul Mode may be used ifthe transmission shifts too often.SeeTo w / H a u l M o d e0282.
When towing at high altitude onsteep uphill grades, consider thefollowing: Engine coolant will boil atalowertemperaturethanatnormalaltitudes. If the engine is turned offimmediately after towing at highaltitude on steep uphill grades, thevehicle may show signs similar toengine overheating. To avoid this,let the engine run while parked,preferably on level ground, with thetransmission in P (Park) for a fewminutes before turning the engineoff. If the overheat warning comeson, seeEngine Overheating0372.
Parking on Hills
{Warning
Parking the vehicle on a hill with
the trailer attached can be
dangerous. If something goes
wrong, the rig could start to move.
People can be injured, and both
the vehicle and the trailer can be
damaged. When possible, always
park the rig on a flat surface.

Trailering is different than justdriving the vehicle by itself.Trailering means changes inhandling, acceleration, braking,durability, and fuel economy.Successful, safe trailering takescorrect equipment, and it has to beused properly.
The following information has manytime-tested, important trailering tipsand safety rules. Many of these are
important for your safety and that ofyour passengers. Read this sectioncarefully before pulling a trailer.
Weight of the Trailer
Safe trailering requires monitoringthe weight, speed, altitude, roadgrades, outside temperature, andhow frequently the vehicle is used topull a trailer. Take into considerationany special equipment on thevehicle, and the amount of tongueweight the vehicle can carry. See“Weight of the Trailer Tongue”laterin this section for more information.
Trailer weight rating (TWR) forpickup models is calculatedassuming the tow vehicle has thedriver, a front seat passenger, andall required trailering equipment.Weight of additional optionalequipment, passengers, and cargoin the tow vehicle must besubtracted from the trailer weightrating.
Ask your dealer for traileringinformation or advice.
For kingpin weight and trailertongue weight information, see“Weight of the Trailer Tongue”laterin this section.
