Using ABS
Do not pump the brakes. Just holdthe brake pedal down firmly and letABS work. You may hear the ABSpump or motor operating and feelthe brake pedal pulsate. This isnormal.
Braking in Emergencies
ABS allows you to steer and brakeat the same time. In manyemergencies, steering can helpmore than even the very bestbraking.
Parking Brake
For vehicles without a releasehandle, set the parking brake byholding the regular brake pedaldown, then pushing down theparking brake pedal.
If the ignition is on, the brakesystem warning light will come on.SeeBrake System WarningLight0140.
Caution
Driving with the parking brake on
can overheat the brake system
and cause premature wear or
damage to brake system parts.
Make sure that the parking brake
is fully released and the brake
warning light is off before driving.

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

Lane Departure Warning
(LDW) (2500/3500 Series)

{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.
