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.

310 Driving and Operating
{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.

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.

is replaced and the sensormatching process is performedsuccessfully. See "TPMS SensorMatching Process" later in thissection.
.The TPMS sensor matchingprocess was not done or notcompleted successfully afterrotating the tires. Themalfunction light and the DICmessage should go off aftersuccessfully completing thesensor matching process. See"TPMS Sensor MatchingProcess" later in this section.
.One or more TPMS sensors aremissing or damaged. Themalfunction light and the DICmessage should go off when theTPMS sensors are installed andthe sensor matching process isperformed successfully. Seeyour dealer for service.
.Replacement tires or wheels donot match the original equipmenttires or wheels. Tires and wheelsother than those recommended
could prevent the TPMS fromfunctioning properly. SeeBuyingNew Tires0415.
.Operating electronic devices orbeing near facilities using radiowave frequencies similar to theTPMS could cause the TPMSsensors to malfunction.
If the TPMS is not functioningproperly, it cannot detect or signal alow tire condition. See your dealerfor service if the TPMS malfunctionlight and DIC message come onand stay on.
TPMS Sensor Matching
Process
Each TPMS sensor has a uniqueidentification code. The identificationcode needs to be matched to a newtire/wheel position after rotating thevehicle’stiresorreplacingoneormore of the TPMS sensors. Also,the TPMS sensor matching processshould be performed after replacingasparetirewitharoadtirecontaining the TPMS sensor. Themalfunction light and the DIC
message should go off at the nextignition cycle. The sensors arematched to the tire/wheel positions,using a TPMS relearn tool, in thefollowing order: driver side front tire,passenger side front tire, passengerside rear tire, and driver side rear.See your dealer for service or topurchase a relearn tool. A TPMSrelearn tool can also be purchased.See Tire Pressure Monitor SensorActivation Tool atwww.gmtoolsandequipment.com orcall 1-800-GM TOOLS(1-800-468-6657).
There are two minutes to match thefirst tire/wheel position, andfive minutes overall to match all fourtire/wheel positions. If it takeslonger, the matching process stopsand must be restarted.
The TPMS sensor matchingprocess is:
1. Set the parking brake.
2. Turn the ignition to ON/RUNwith the engine off.
