GENERAL INFORMATION
Note:Occasional brake noise is normal. Ifa metal-to-metal, continuous grinding orcontinuous squeal sound is present, thebrake linings may be worn-out. Have thesystem checked by an authorized dealer. Ifyour vehicle has continuous vibration orshudder in the steering wheel while braking,have it checked by an authorized dealer.
Note:Brake dust may accumulate on thewheels, even under normal drivingconditions. Some dust is inevitable as thebrakes wear and does not contribute tobrake noise. See Cleaning the AlloyWheels (page 261).
See Warning Lamps andIndicators (page 77).
Wet brakes result in reduced brakingefficiency. Gently press the brake pedal afew times when driving from a car wash orstanding water to dry the brakes.
Brake Over Accelerator
In the event the accelerator pedalbecomes stuck or entrapped, apply steadyand firm pressure to the brake pedal toslow the vehicle and reduce engine power.If you experience this condition, apply thebrakes and bring your vehicle to a safestop. Move the transmission selector leverto position P, switch the engine off andapply the parking brake. Inspect theaccelerator pedal for any interference. Ifnone are found and the condition persists,have your vehicle towed to the nearestauthorized dealer.
Brake Assist
Brake assist detects when you brakerapidly by measuring the rate at which youpress the brake pedal. It providesmaximum braking efficiency as long as youpress the pedal, and can reduce stoppingdistances in critical situations.
Anti-lock Brake System
This system helps you maintain steeringcontrol during emergency stops by keepingthe brakes from locking.
This lamp momentarilyilluminates when you turn theignition on. If the light does notilluminate during start up, remains on orflashes, the system may be disabled. Havethe system checked by an authorizeddealer.
If the system is disabled, normalbraking is still effective. If thebrake warning lamp illuminateswhen you release the parking brake, havethe system checked by an authorizeddealer.
HINTS ON DRIVING WITH
ANTI-LOCK BRAKES
Note:When the system is operating, thebrake pedal will pulse and may travelfurther. Maintain pressure on the brakepedal. You may also hear a noise from thesystem. This is normal.
The anti-lock braking system will noteliminate the risks when:
•you drive too closely to the vehicle infront of you
•your vehicle is hydroplaning
•you take corners too fast
•the road surface is poor.

PARKING BRAKE
WARNING
Always set the parking brake fullyand make sure the transmissionselector lever is placed in position P.Failure to set the parking brake and engagepark could result in vehicle roll-away,property damage or bodily injury. Turn theignition to the lock position and removethe key whenever you leave your vehicle.
Apply the parking brake whenever yourvehicle is parked. Press the pedaldownward to set the parking brake. Thebrake warning lamp in the instrumentcluster will illuminate and remainsilluminated until the parking brake isreleased.
To release, pull the brake release leverlocated at the lower left side of theinstrument panel.
If you are parking your vehicle on a gradeor with a trailer, press and hold the brakepedal down, then set the parking brake.There may be a little vehicle movement asthe parking brake sets to hold the vehicle'sweight. This is normal and should be noreason for concern. If needed, press andhold the service brake pedal down, thentry reapplying the parking brake. Chock thewheels if required. If the parking brakecannot hold the weight of the vehicle, theparking brake may need to be serviced orthe vehicle may be overloaded.
HILL START ASSIST
WARNINGS
The system does not replace theparking brake. When you leave yourvehicle, always apply the parkingbrake and put the transmission in park (P).
WARNINGS
You must remain in your vehicle onceyou have activated the system.
During all times, you are responsiblefor controlling your vehicle,supervising the system andintervening, if required.
If the engine is revved excessively, orif a malfunction is detected, thesystem will be deactivated.
The system makes it easier to pull awaywhen your vehicle is on a slope without theneed to use the parking brake.
When the system is active, your vehicle willremain stationary on the slope for two tothree seconds after you release the brakepedal. This allows you time to move yourfoot from the brake to the acceleratorpedal. The brakes are releasedautomatically once the engine hasdeveloped sufficient drive to prevent yourvehicle from rolling down the slope. Thisis an advantage when pulling away on aslope, (for example from a car park ramp,traffic lights or when reversing uphill intoa parking space).
The system will activate automatically onany slope that will cause significant vehiclerollback.
Using Hill Start Assist
1.Press the brake pedal to bring yourvehicle to a complete standstill. Keepthe brake pedal pressed.
2.If the sensors detect that your vehicleis on a slope, the system will activateautomatically.
3.When you remove your foot from thebrake pedal, your vehicle will remainon the slope without rolling away forabout two or three seconds. This holdtime will automatically be extended ifyou are in the process of driving off.

PRINCIPLE OF OPERATION
The traction control system helps avoiddrive wheel spin and loss of traction.
If your vehicle begins to slide, the systemapplies the brakes to individual wheelsand, when needed, reduces engine powerat the same time. If the wheels spin whenaccelerating on slippery or loose surfaces,the system reduces engine power in orderto increase traction.
USING TRACTION CONTROL
(Dual rear wheel vehicles only)
In certain situations (for example, stuck insnow or mud), it may be beneficial to turnthe traction control system off. This allowsthe wheels to spin with full engine power.
Turn the traction control system off bypressing the stability control buttonlocated on the instrument panel.
If you cannot turn the system off, see theMyKey chapter for more information.
Placing your vehicle into four-wheel drivemode automatically disables tractioncontrol. Traction control operation willresume when you place your vehicle backinto two-wheel drive mode.

PRINCIPLE OF OPERATION
WARNINGS
Hill descent control cannot controldescent in all surface conditions andcircumstances, such as ice orextremely steep grades. Hill descentcontrol is a driver assist system and cannotsubstitute for good judgment by the driver.Failure to do so may result in loss of vehiclecontrol, crash or serious injury.
Hill descent control does not providehill hold at zero miles per hour (0kilometers per hour). When stopped,the parking brake must be applied or thevehicle must be placed in P (Park) or itmay roll away.
Hill descent control allows the driver to setand maintain vehicle speed whiledescending steep grades in various surfaceconditions.
Hill descent control can maintain vehiclespeeds on downhill grades between 2 mph(3 km/h) and 12 mph (20 km/h). Above 20mph (32 km/h), the system remainsarmed, but descent speed cannot be setor maintained.
Hill descent control requires a coolingdown interval after a period of sustaineduse. The amount of time that the featurecan remain active before cooling varieswith conditions. The system will provide awarning in the message center and a chimewill sound when the system is about todisengage for cooling. At this time,manually apply the brakes as needed tomaintain descent speed.
USING HILL DESCENT
CONTROL
Press and release the hilldescent button located on theinstrument panel. A light in thecluster will illuminate and achime will sound when this feature isactivated.
To increase descent speed, press theaccelerator pedal until the desired speedis reached. To decrease descent speed,press the brake pedal until the desiredspeed is reached.
Whether accelerating or decelerating, oncethe desired descent speed is reached,remove your feet from the pedals and thechosen vehicle speed will be maintained.
Note:Noise from the ABS pump motor maybe observed during hill descent controloperation. This is a normal characteristic ofthe ABS and should be no reason forconcern.
Hill descent modes
•At speeds below 20 mph (32 km/h):When the Hill Descent Control switchis pressed and Hill Descent Control isactive, the Hill Descent Control telltalewill flash.
•At speeds below 20 mph (32 km/h):When the Hill Descent Control switchis pressed and conditions are notcorrect for hill descent activation, theHill Descent Control system will beenabled, the Hill Descent Controltelltale will be solid and a message willdisplay in the information display.

PARKING AID (IF EQUIPPED)
WARNINGS
To help avoid personal injury, pleaseread and understand the limitationsof the system as contained in thissection. Sensing is only an aid for some(generally large and fixed) objects whenmoving in reverse on a flat surface atparking speeds. Traffic control systems,inclement weather, air brakes, and externalmotors and fans may also affect thefunction of the sensing system; this mayinclude reduced performance or a falseactivation.
To help avoid personal injury, alwaysuse caution when in R (Reverse) andwhen using the sensing system.
This system is not designed toprevent contact with small or movingobjects. The system is designed toprovide a warning to assist the driver indetecting large stationary objects to avoiddamaging the vehicle. The system may notdetect smaller objects, particularly thoseclose to the ground.
Certain add-on devices such as largetrailer hitches, bike or surfboard racksand any device that may block thenormal detection zone of the system, maycreate false beeps.
Note:Keep the sensors, located on thebumper or fascia, free from snow, ice andlarge accumulations of dirt. If the sensorsare covered, the system’s accuracy can beaffected. Do not clean the sensors withsharp objects.
Note:If your vehicle sustains damage tothe bumper or fascia, leaving it misalignedor bent, the sensing zone may be alteredcausing inaccurate measurement ofobstacles or false alarms.
Note:If your vehicle is equipped withMyKey™, it is possible to prevent turningthe sensing system off. See MyKey™ (page50).
Note:If your vehicle is equipped with a fullyintegrated electronic trailer brake controller(TBC) and a trailer with electric trailerbrakes is connected to your vehicle, the RSSwill be disabled. When the vehicle is shiftedinto reverse, the information display willremain in the Rear Park Aid Off selection.For more information on the TBC, SeeTrailer Sway Control (page 190).
The sensing system warns the driver ofobstacles within a certain range of thebumper area. The system turns onautomatically whenever the ignition isswitched on.
When receiving a detection warning, theradio volume is reduced to apredetermined level. After the warninggoes away, the radio volume returns to theprevious level.
Rear Sensing System
The rear sensors are only active when thetransmission is in R (Reverse). As thevehicle moves closer to the obstacle, therate of the audible warning increases.When the obstacle is fewer than 12 inches(30 centimeters) away, the warningsounds continuously. If a stationary orreceding object is detected farther than 12inches (30 centimeters) from the side ofthe vehicle, the tone sounds for only threeseconds. Once the system detects anobject approaching, the warning soundsagain.

for operation at Gross VehicleWeight Rating, not at GrossCombined Weight Rating.)Separate functional brakes shouldbe used for safe control of towedvehicles and for trailers where theGross Combined Weight of thetowing vehicle plus the trailerexceed the Gross Vehicle WeightRating of the towing vehicle.TheGross Combined Weight mustnever exceed the GrossCombined Weight Rating.
Maximum Loaded TrailerWeight - is the highest possibleweight of a fully loaded trailer thevehicle can tow. It assumes avehicle with mandatory options,driver and front passenger weight(150 pounds [68 kilograms]each), no cargo weight (internalor external) and a tongue load of10–15% (conventional trailer) orking pin weight of 15–25% (fifthwheel trailer). Consult anauthorized dealer (or the RV andTrailer Towing Guide available atan authorized dealer) for moredetailed information.
Tongue Load or Fifth WheelKing Pin Weight - refers to theamount of the weight that a trailerpushes down on a trailer hitch.
Examples: For a 5000 pound(2268 kilogram) conventionaltrailer, multiply 5000 by 0.10 and0.15 to obtain a proper tongueload range of 500 to 750 pounds(227 to 340 kilograms). For an11500 pound (5216 kilogram) fifthwheel trailer, multiply by 0.15 and0.25 to obtain a proper king pinload range of 1725 to 2875 pounds(782 to 1304 kilograms).
WARNINGS
Do not exceed the GVWR orthe GAWR specified on theSafety Compliance CertificationLabel.
Do not use replacement tireswith lower load carryingcapacities than the original tiresbecause they may lower thevehicle’s GVWR and GAWRlimitations. Replacement tireswith a higher limit than the originaltires do not increase the GVWRand GAWR limitations.
Exceeding any vehicle weightrating limitation could resultin serious damage to the vehicleand/or personal injury.
Steps for determining thecorrect load limit:
1.Locate the statement "Thecombined weight of occupantsand cargo should never exceedXXX kg or XXX lb." on yourvehicle’s placard.

TOWING A TRAILER
WARNINGS
Do not exceed the GVWR orthe GAWR specified on thecertification label.
Towing trailers beyond themaximum recommendedgross trailer weight exceeds thelimit of the vehicle and couldresult in engine damage,transmission damage, structuraldamage, loss of vehicle control,vehicle rollover and personalinjury.
Your vehicle may have electricalitems, such as fuses or relays,related to towing. See the Fuseschapter.
Your vehicle's load capacitydesignation is by weight, not byvolume, so you cannot necessarilyuse all available space whenloading a vehicle.
Towing a trailer places an extraload on your vehicle's engine,transmission, axle, brakes, tiresand suspension. Inspect thesecomponents periodically during,and after, any towing operation.
Load Placement
To help minimize how trailermovement affects your vehiclewhen driving:
•Load the heaviest items closestto the trailer floor.
•Load the heaviest itemscentered between the left andright side trailer tires.
•Load the heaviest items abovethe trailer axles or just slightlyforward toward the trailertongue. Do not allow the finaltrailer tongue weight to goabove or below 10-15% of theloaded trailer weight.
•Select a tow bar with thecorrect rise or drop. When boththe loaded vehicle and trailerare connected, the trailer frameshould be level, or slightlyangled down toward yourvehicle, when viewed from theside.
When driving with a trailer orpayload, a slight takeoff vibrationor shudder may be present due tothe increased payload weight.Additional information regardingproper trailer loading and settingyour vehicle up for towing islocated in another chapter of thismanual. See Load Limit (page178). You can also find theinformation in the RV & TrailerTowing Guide, available at anauthorized dealer.

TRAILER SWAY CONTROL (IF
EQUIPPED)
WARNING
Turning off trailer sway controlincreases the risk of loss of vehiclecontrol, serious injury or death. Forddoes not recommend disabling this featureexcept in situations where speed reductionmay be detrimental (such as hill climbing),the driver has significant trailer towingexperience, and can control trailer swayand maintain safe operation.
Note:This feature does not prevent trailersway, but reduces it once it begins.
Note:This feature cannot stop all trailersfrom swaying.
Note:In some cases, if vehicle speed is toohigh, the system may activate multipletimes, gradually reducing vehicle speed.
This feature applies your vehicle brakes atindividual wheels and, if necessary, reducesengine power. If the trailer begins to sway,the stability control light flashes and themessage TRAILER SWAY REDUCESPEED appears in the information display.The first thing to do is slow your vehicledown, then pull safely to the side of theroad and check for proper tongue load andtrailer load distribution. See LoadCarrying (page 178).
RECOMMENDED TOWING
WEIGHTS
Note:Do not exceed a trailerweight of 5000 pounds (2268kilograms) when towing with, orby, bumper only.
Note:Make sure to take intoconsideration trailer frontal area.Do not exceed 60 feet2 (5.6
meters2) trailer frontal area.
Note:Exceeding this limitationmay significantly reduce theperformance of your towingvehicle. Selecting a trailer with alow aerodynamic drag and roundedfront design helps optimizeperformance and fuel economy.
Note:For high altitude operation,reduce the gross combined weightby 2% per 1000 feet (300 meters)starting at the 1000 foot (300meter) elevation point.
Note:Certain states requireelectric trailer brakes for trailersover a specified weight. Be sure tocheck state regulations for thisspecified weight. The maximumtrailer weights listed may be limitedto this specified weight, as yourvehicle's electrical system may notinclude the wiring connectorneeded to use electric trailerbrakes.
Your vehicle may tow a class I, II,III and IV trailer or fifth-wheeltrailer provided the maximumtrailer weight is less than or equalto the maximum trailer weightlisted for your vehicleconfiguration on the followingchart.
