In order to prevent the engine from runningat too low an RPM, which may cause it tostall, SelectShift will still automaticallymake some downshifts if it has determinedthat you have not downshifted in time.Although SelectShift will make somedownshifts for you, it will still allow you todownshift at any time as long as theSelectShift determines that damage willnot be caused to the engine fromover-revving.
SelectShift will not automatically upshift,even if the engine is approaching the RPMlimit. It must be shifted manually bypressing the + button.
Note:Engine damage may occur if youmaintain excessive engine revving withoutshifting.
The SelectShift Automatic transmissionfeature has two modes: PRS and M mode.
PRS (Progressive Range Selection)
Progressive Range Selection gives you theability to lockout gears from the automaticshifting range. This may provide you withan improved driving experience (forexample, in slippery conditions or whenexperiencing a steep grade).
With the gearshift lever in drive (D), pressthe – button to active PRS. The availableand selected gears are indicated on theinstrument cluster.
All available gears will display with thecurrent gear indicated. Press the – buttonagain to lock out gears beginning with thehighest gear. Example: press the – buttontwice to lock out 6th and 5th gears. Onlythe available gears will display and thetransmission will automatically shiftbetween the available gears. Press the +button to unlock gears to allow thetransmission to shift to higher gears. Thetransmission will shift automatically withinthe gear range you select.
Manual (M)
Moving the gearshift lever to the manual(M) position will allow you to manuallyselect the gear you desire. Only the currentgear will display. Use the buttons on thegearshift lever to manually select gears.Press the + button to upshift or the –button to downshift.

Hitches
Note:On pick-up trucks, the trailer hitchprovided on this vehicle enhances crashprotection for the fuel system. Do notremove!
Note:Do not cut, drill, weld or modify trailerhitches. Modifying trailer hitches can reducehitch rating.
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% for conventional towing or15-25% for fifth wheel towing of the totalweight of the trailer is on the tongue.
Hitch components (If Equipped)
The following components will be includedin certain vehicles.
•A 5/8 inch hitch pin rated to tow up to21,000 lbs.
•A 3 inch drawbar.
•A hitch pin sleeve to be used whenmounting the 3 inch drawbar.
•A clevis pin to help keep the hitch pinin place.
Weight-distributing Hitches
WARNING
Do not adjust the spring bars so thatyour vehicle's rear bumper is higherthan before attaching the trailer.Doing so will defeat the function of theweight-distributing hitch, which may causeunpredictable handling, and could resultin serious personal injury.
When hooking-up a trailer using aweight-distributing hitch, always use thefollowing procedure:
1. Park the loaded vehicle, without thetrailer, on a level surface.
2. Measure the height to the top of yourvehicle's front wheel opening on thefender. This is H1.
3.Attach the loaded trailer to your vehiclewithout the weight-distributing barsconnected.
4. Measure the height to the top of yourvehicle's front wheel opening on thefender a second time. This is H2.
5. Install and adjust the tension in theweight-distributing bars so that theheight of your vehicle's front wheelopening on the fender is approximatelyhalfway between H1 and H2.
6.Check that the trailer is level or slightlynose down toward your vehicle. If not,adjust the ball height accordingly andrepeat Steps 2-6.
