Using the Pre-Collision AssistSystem
The pre-collision assist system is active atspeeds above 3 mph (5 km/h).
If your vehicle is rapidly approachinganother stationary vehicle or a vehicletraveling in the same direction the systemprovides three levels of functionality:
1.Alert.
2.Brake support.
3.Active braking.
Alert: When active, a flashing visualwarning appears and an audible warningtone sounds.

Brake support: Helps reduce the impactspeed by preparing the brakes for rapidbraking. The system does notautomatically apply the brakes. If you pressthe brake pedal, the system could applyadditional braking up to maximum brakingforce, even if you lightly press the brakepedal.
Active braking: May activate if the systemdetermines that a collision is imminent.The system may help the driver reduceimpact damage or avoid the crashcompletely.
Note:If you perceive pre-collision assistalerts as being too frequent, then you canreduce the alert sensitivity, though themanufacturer recommends using thehighest sensitivity setting where possible.Setting lower sensitivity would lead to fewerand later system warnings.
Distance Indication and Alert
Provides the driver with a graphicalindication of the time gap to otherpreceding vehicles traveling in the samedirection. The distance indication and alertscreen in the instrument cluster displayshows one of the following graphics.
If the time gap to a preceding vehicle issmall, a red visual indication displays.
Adjusting the Pre-Collision AssistSettings
You can adjust the following settings byusing the instrument cluster displaycontrols. See General Information (page71).
•You can change alert and distancealert sensitivity to one of three possiblesettings.
•You can switch distance indication andalert on or off.
•If required, you can switch activebraking on or off.
•If required, you can switch the entirepre-collision assist feature on or off.
Note:Active braking automatically turnson every time you switch the ignition on.

AIR SUSPENSION
Note:Do not operate your vehicle withoutair in the suspension springs. Operating yourvehicle without air in the suspension springsdamages the suspension, degrades rideperformance and may cause propertydamage.
The air suspension system automaticallyadjusts to different loads to maintain aconstant frame height, allows for ease ofvehicle loading, provides improved vehicleride, and increased driver comfort.
Air Suspension Dump Button
Note:The suspension dumps air when theignition is in the accessory or on position,but fills only when the ignition is in the onposition.
A button located on the instrument panelcontrols the system. It operates only whenthe ignition is in the accessory or onposition and the air tanks have sufficientpressure to fill the air springs. When youturn off the ignition, the suspensionremains in whatever state it was last set.
Pressing and holding the button for twoseconds exhausts air from the air springs,lowering the frame for loading. Pressingand holding the button for two secondsfills the air springs so your vehicle remainsat normal ride height.
System Indicator Light
The air suspension indicator lightilluminates when using the button torelease air pressure in the rear air springs.Never drive your vehicle when the warninglamp is illuminated and there is low (or no)air pressure in the springs.
Connecting and Disconnecting aTrailer with Air Suspension and AirSuspension Dump Button
When connecting to a trailer:
•Press and hold the button for twoseconds to exhaust air from the airsuspension system.
•Press and hold the button for twoseconds, and then raise the landinggear after making the connection tothe trailer.
When disconnecting the trailer:
•Lower the landing gear, and then pressand hold the button for two seconds.
•Disconnect the brake hoses, trailer-sideand rear light connectors, then pull therelease lever on the fifth wheel.
You must fill the air springs beforeoperating with a trailer or operating in thebobtail mode.
Suspension Conversions
WARNING: When operating aloaded vehicle, the driver must keep alladjustable axles on the ground at alltimes, supporting their share of thevehicle’s load. Failure to do so canoverload other axles, tires, wheels,springs, steering components, brakesand frames, resulting in early componentfailure, loss of vehicle control, possibleproperty damage and personal injury.

TOWING A TRAILER
WARNING: Do not exceedthe GVWR or the GAWRspecified on the certificationlabel.
WARNING: Towing trailersbeyond the maximumrecommended gross trailerweight exceeds the limit of thevehicle and could result in enginedamage, transmission damage,structural damage, loss ofvehicle control, vehicle rolloverand personal injury.
Your vehicle may have electricalitems, such as fuses or relays,related to towing. See Fuses(page 202).
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.
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).

ESSENTIAL TOWING CHECKS
See Load limits in the Load Carryingchapter for load specification terms foundon the tire label and Safety Compliancelabel and instructions on calculating yourvehicle's load.
Remember to account for the trailertongue weight as part of your vehicle loadwhen calculating the total vehicle weight.
Hitches
Do not use a hitch that either clamps ontothe bumper or attaches to the axle. Youmust distribute the load in your trailer sothat 10-15% of the total weight of thetrailer is on the tongue.
Safety Chains
Note:Do not attach safety chains to thebumper.
Always connect the safety chains to theframe or hook retainers of your vehiclehitch.
To connect the safety chains, cross thechains under the trailer tongue and allowenough slack for turning tight corners. Donot allow the chains to drag on the ground.
Trailer Brakes
WARNING: Do not connect atrailer's hydraulic brake system directlyto your vehicle's brake system. Yourvehicle may not have enough brakingpower and your chances of having acollision greatly increase.
Electric brakes and manual, automatic orsurge-type trailer brakes are safe if youinstall them properly and adjust them tothe manufacturer's specifications. Thetrailer brakes must meet local and federalregulations.
The rating for the tow vehicle's brakingsystem operation is at the gross vehicleweight rating, not the gross combinedweight rating.
Trailer Lamps
WARNING: Never connect anytrailer lamp wiring to the vehicle's taillamp wiring; this may damage theelectrical system resulting in fire. Contactyour authorized dealer as soon aspossible for assistance in proper trailertow wiring installation. Additionalelectrical equipment may be required.
Trailer lamps are required on most towedvehicles. Make sure all running lights, brakelights, turn signals and hazard lights areworking.
Before Towing a Trailer
Practice turning, stopping and backing upto get the feel of your vehicle-trailercombination before starting on a trip.When turning, make wider turns so thetrailer wheels clear curbs and otherobstacles.
When Towing a Trailer
•Check your hitch, electrical connectionsand trailer wheel lug nuts thoroughlyafter you have traveled 50 mph(80 km/h).
•When stopped in congested or heavytraffic during hot weather, place thetransmission in park (P) or neutral (N)to aid engine and transmission coolingand to help air conditioningperformance.
•Turn off the speed control with heavyloads or in hilly terrain. The speedcontrol may turn off automaticallywhen you are towing on long, steepgrades.
183

•Shift to a lower gear when driving downa long or steep hill. Do not apply thebrakes continuously, as they mayoverheat and become less effective.
•If your transmission is equipped withthe Tow/Haul feature, use this featurewhen towing. This provides enginebraking and helps eliminate excessivetransmission shifting for optimum fueleconomy and transmission cooling.
•Allow more distance for stopping witha trailer attached. Anticipate stops andbrake gradually.
FIFTH WHEEL OPERATION (IF
EQUIPPED)
WARNING: Failure to follow thefifth wheel manufacturer’s instructionsfor hooking and unhooking as well assliding the fifth wheel could result in anaccident, personal injury or death.
