Brake Assist
The Brake Assist feature isdesigned to assist the driver instopping or decreasing vehiclespeed in emergency drivingconditions. This feature uses thestability system hydraulic brakecontrol module to supplement thepower brake system underconditions where the driver hasquickly and forcefully applied thebrake pedal in an attempt to quicklystop or slow down the vehicle. Thestability system hydraulic brakecontrol module increases brakepressure at each corner of thevehicle until the ABS activates.Minor brake pedal pulsation orpedal movement during this time isnormal and the driver shouldcontinue to apply the brake pedal asthe driving situation dictates TheBrake Assist feature willautomatically disengage when thebrake pedal is released or brakepedal pressure is quicklydecreased.
Hill Start Assist (HSA)
This vehicle has a Hill Start Assist(HSA) feature, which may be usefulwhen the vehicle is stopped on agrade. This feature is designed toprevent the vehicle from rolling,either forward or rearward, duringvehicle drive off. After youcompletely stop and hold the vehiclein a complete standstill on a grade,HSA will automatically activate.During the transition period betweenwhen you release the brake pedaland start to accelerate to drive offon a grade, HSA holds the brakingpressure for a maximum oftwo seconds to ensure that there isno rolling. The brakes willautomatically release when theaccelerator pedal is applied withinthe two-second window. If thevehicle is equipped with theIntegrated Trailer Brake Control(ITBC) system, HSA may also applythe trailer brakes. It will not activateif the vehicle is in a drive gear and

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

Driving and Operating 305
display green. Vehicles may not bedetected on curves, highway exitramps, or hills, due to poor visibility;or if a vehicle ahead is partiallyblocked by pedestrians or otherobjects. FCA will not detect anothervehicle ahead until it is completelyin the driving lane.
{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.
Selecting the Alert Timing
The Collision Alert control is on the
steering wheel. Press[to set the
FCA timing to Far, Medium, Near,

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.

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.
