To prevent the engine from running at toolow an RPM, which could cause it to stall,SelectShift still makes some downshiftsif it has determined that you have notdownshifted in time. Although SelectShiftmakes some downshifts for you, it stillallows you to downshift at any time if theSelectShift determines that there is nodamage to the engine from over-revving.
SelectShift does not automatically upshift,even if the engine is approaching the RPMlimit. Shift manually by pressing the (+)button.
Note:Engine damage could occur if you revthe engine excessively and hold it withoutshifting.
Progressive Range Selection (If
Equipped)
Progressive range selection gives you theability to lockout gears from the automaticshifting range. This could provide you withan improved driving experience, forexample, in slippery conditions or whenexperiencing a steep slope.

Push the palm release lever (A) on theparking brake handle (B) and push downas far as possible to release the brake.Driving with the parking brake on causesthe brakes to wear out quickly and reducesfuel economy.
We recommend you not use the parkingbrake to stop a moving vehicle. However,if the normal brakes fail, you can use theparking brake to stop your vehicle in anemergency. Since the parking brake onlyapplies retardation to the rear wheels, thevehicle's stopping distance increasesgreatly and the handling of your vehicle isadversely affected.
Releasing Spring Manually
WARNING: Do not attempt todisassemble the parking brake airchamber under any circumstances asthis may cause serious injury.
WARNING: Block the wheels tohelp prevent the vehicle from moving.
WARNING: Unexpected andpossibly sudden vehicle movement mayoccur if you do not take theseprecautions.
If you release hydraulic pressure from thespring brake chamber, the power springapplies the brake. If the hydraulic pressurecan be re-established, you must releasethe spring brake in order to move yourvehicle.
Air Brakes (If Equipped)
WARNING: This control is forparking only. Do not leave the vehicleunattended after setting the parkingbrake without placing the transmissionin park (P). We recommend using wheelchocks for hilly or off-roadcircumstances.
If the service brakes fail to operate whileyour vehicle is moving, you can make anemergency stop with the parking brake.Since the parking brake only appliesstopping power to the rear wheels, yourvehicle’s stopping distance greatlyincreases and the handling of your vehicleis adversely affected. Make repairsimmediately to an inoperative air brakesystem circuit.
Pull the yellow, dash-mounted parkingbrake knob to apply the parking brake.
The parking brake lightilluminates and remainsilluminated (when you switchthe ignition to the on position) until yourelease the parking brake.

5.Tighten the nut until the spring is fullycaged and brakes released. Do notloosen or remove the release stud andnut unless you completely assembleand securely clamp the brake chamber.
6.After restoring the air pressure,unscrew and remove the release studand install in the carrying pocket. Installthe access plug.
HILL START ASSIST -
VEHICLES WITH: HYDRAULIC
BRAKES
WARNING: The system does notreplace the parking brake. When youleave your vehicle, always apply theparking brake.
WARNING: You must remain inyour vehicle when the system turns on.At all times you are responsible forcontrolling your vehicle, supervising thesystem, and intervening if required.Failure to follow this instruction couldresult in the loss of control of yourvehicle, personal injury or death.
WARNING: The system will turnoff if a malfunction is apparent or if yourev the engine excessively. Failure to takecare may result in the loss of control ofyour vehicle, serious personal injury ordeath.
The system makes it easier to pull awaywhen your vehicle is on a slope withoutneeding to use the parking brake.
When the system is active, your vehicleremains stationary on the slope for two tothree seconds after you release the brakepedal. This allows time to move your footfrom the brake to the accelerator pedal.The brakes release when the engine has
developed sufficient torque 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.
When the vehicle is on a slope, the systemwill turn on automatically to preventvehicle rollback.
Note:There is no warning light to indicatethe system is either on or off.
Using Hill Start Assist
1.Press the brake pedal to bring yourvehicle to a complete standstill. Keepthe brake pedal pressed and shift intogear when facing uphill or reverse (R)when facing downhill.
2.If the sensors detect that your vehicleis on a slope, the system automaticallyactivates.
3.When you remove your foot from thebrake pedal, your vehicle remains onthe slope without rolling away forabout two to three seconds. This holdtime automatically extends if you arein the process of driving off.
4.Drive off in the normal manner. Thesystem releases the brakesautomatically.
Note:When you remove your foot from thebrake pedal and press the pedal again whenthe system is active, you will experiencesignificantly reduced brake pedal travel. Thisis normal.

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).
You can also find information inthe RV & Trailer Towing Guideavailable at your authorizeddealer, or online.

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.

ELECTRICAL SYSTEM
INSPECTION
Periodically inspect electrical connectorson the outside of the cab and on the engineand frame for corrosion and tightness.Exposed terminals, such as the fuel sender,cranking motor, alternator andfeed-through studs, should be cleaned andre-coated with a lubricant sealing greasesuch as Motorcraft Silicone Brake CaliperGrease and Dielectric Compound XG-3, orequivalent. This should include the groundcable connector for batteries, engine andcab as well as the jump-starting stud.
Accessory Feed Connections
Vehicle electrical systems are complex andoften include powertrain components,such as engine and transmission controls,instrument panels and ABS. While mostsystems operate on battery voltage (12volts), some systems can be as high as 90volts or as low as five volts. See theElectrical Circuit Diagram Manuals,available from your vehicle’s manufacturer,to make sure that any extra body lights andaccessory connections to circuits are bothappropriate and not overloaded. Do notmake modifications to any vehicle controlsystem without first contacting anauthorized dealer.

•Maintaining proper steering gear andpower steering pump lubricant levels.
•Checking steering column joint boltsand steering linkage, particularly forbody-to-chassis clearance.
Steering Column Joint Bolts
As a good maintenance practice, checksteering column joint bolt tightness every60,000 mi (96,000 km) or annually,whichever occurs first. Do not overtightenthe bolts.
Hydraulic System
Whenever draining and refilling the powersteering's hydraulic system for any reason,bleed air from the system before returningthe vehicle to service. Failure to bleed thehydraulic system properly can result indegradation of power system performance.
Consult an authorized dealer who is awareof the proper procedures for filling andbleeding the system.
SUSPENSION SYSTEM
INSPECTION (IF EQUIPPED)
Note:Do not adjust air suspension heightto any setting other than the specifiedsetting. Altering the height setting changesthe driveline angle and may result inunwarrantable component damage, suchas transmission component damage.
Verify drive axle air suspension height andheight control valve performance at engineoil change intervals.
Periodically check:
•Condition of spring leaves for evidenceof fatigue, bending or breakage.
•Condition of suspension mountingbrackets and bushings.
•Torque rod mounting fasteners fortightness.
•For proper suspension alignment.Maintain proper alignment at all times.
•U-bolts. After the chassis has beenoperating under load for 1,000 mi(1,600 km) or six months (whichevercomes first), the U-bolt nuts must bere-torqued. Re-torque the U-bolt nutsevery 37,000 mi (60,000 km)thereafter. Clean and lubricate theU-bolt and nut threads and seats tomake sure a like new condition whenre-torqueing. See Spring U-BoltCheck (page 261).
FRAME AND TOW HOOK
INSPECTION
Your vehicle's chassis is manufacturedwith frame rails of either HSLA steel orheat-treated steel. Handle each in aspecific manner to make sure maximumservice life. Consult the service manual oran authorized dealer before attemptingframe repair or modification.
It is important, particularly on vehicles thatuse tow hooks frequently, to inspect thefront and rear tow hooks for damage or aloose mounting.
REAR AXLE FLUID CHECK
Your rear axle may have an optionalsynthetic lubricant that allows the use ofextended service intervals. A tag on thefiller plug identifies the use of the syntheticlubricant.
Only use a lubricant that meetsmanufacturer specifications. Use of anon-approved rear axle lubricant maycause internal axle component damage.See Rear Axle Fluid Capacity andSpecification (page 311).
Checking the Fluid Level
1.Park your vehicle on level ground.
