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).

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.

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.

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.
