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,

Warning (Continued)
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.
Turning the Features On or Off
TheXbutton on the center stack
is used to turn on or off the Frontand Rear Parking Assist. Theindicator light in the button comeson when the features are on andturns off when the features havebeen disabled.

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

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
The LDW camera sensor is on thewindshield ahead of the rearviewmirror.

When LDW is on,@is green if
LDW is available to warn of a lanedeparture. If the vehicle crosses adetected lane marking without using
the turn signal in that direction,@
changes to amber and flashes.Additionally, there will be threebeeps, or the driver seat will pulsethree times on the right or left,depending on the lane departuredirection.
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.

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 using a weight-distributinghitch, measure distance (2) beforecoupling the trailer to the hitch ball.Measure the height again after thetrailer is coupled and adjust thespring bars so the distance (2) is asclose as possible to halfwaybetween the two measurements.
Fifth-Wheel and Gooseneck
Trailering
Fifth-wheel and gooseneck trailerscan be used with many pickupmodels. These trailers place alarger percentage of the weight(kingpin weight) on the tow vehicle
than conventional trailers. Makesure this weight does not cause thevehicle to exceed GAWR or GVWR.
Fifth-wheel or gooseneck kingpinweight should be 15 to 25% of thetrailer weight up to the maximumamount specified in the traileringchart for the vehicle. See“Weight ofthe Trailer”underTr a i l e rTo w i n g0318.
The hitch should be located in thepickup bed so that its centerline isover or slightly in front of the rearaxle. Take care that it is not so farforward that it will contact the backof the cab in sharp turns. This isespecially important for short box

Trailer Sway
Control (TSC)
Vehicles with StabiliTrak have aTrailer Sway Control (TSC) feature.Trailer sway is unintendedside-to-side motion of a trailer whilebeing towed. If the vehicle is towingatrailerandtheTSCdetectsthatsway is increasing, the vehiclebrakes are selectively applied ateach wheel, to help reduceexcessive trailer sway. If the vehicleis equipped with the IntegratedTrailer Brake Control (ITBC) system,and the trailer has the electricactuated brake system, StabiliTrakmay also apply the trailer brakes.
If TSC is enabled, the TractionControl System (TCS)/StabiliTrakwarning light will flash on theinstrument cluster. Vehicle speedmust be reduced. If trailer swaycontinues, StabiliTrak can reduceengine torque to help slow thevehicle. SeeTr a c t i o n C o n t r o l /Electronic Stability Control0295.
{Warning
Even if the vehicle is equipped
with TSC, trailer sway could result
in loss of control and the vehicle
could crash. If excessive trailer
sway is detected, slow down to a
safe speed. Check the trailer and

causes. These could include an
