I Here are somethingsyou whengoingupahill. 8 mustnot do if youstall, or areabout to stall, Neverattempt to preventastall by shifting into N (Neutral)(or depressingtheclutch, if youhaveamanualtransmission) to "rev-up"the engine and regainforwardmomentum.Thiswon'twork. Your vehiclewill roll backwardsveryquicklyandyou could goout of control. Instead,applytheregularbraketostopthevehicle.Thenapplytheparking brake.Shiftintoreverse,releasetheparkingbrake, and slowlybackdown. 8 Neverattempttoturnaround if youareabouttostallwhengoingupa hill. If thehillissteepenough to stallyourvehicle,it'ssteepenough to causeyou to roll over if youturnaround. If youcan'tmake it upthe hill, youmustbackdownthehill. Q: Suppose, after stalling, I try to back down the hill and decide I just can't do it. What should I do? A: Set theparkingbrake, put yourtransmission in P (Park) (or the manual transmission in firstgear), and turn off theengine.Leavethevehicleandgo getsomehelp.Exitontheuphillsideandstayclearofthe path thevehicle to M (Neutral) wouldtake if it rolleddownhill. Do notshiftthetransfercase whenyouleavethevehicle.Leave it in somegear. Shifting the transfer case to W (Neutral) can cause your vehicle to roll even if thetransmission is in P (Park) (or, if youhave the manualtransmission,even if you're in gear).This is because ttie 5\1 (Neutral)position on thetransfercaseoverrides the transmission. If youaregoing to leaveyourvehicle,set the parkingbrake and shift thetransmission to P (Park) (or, put yourmanualtransmission in first gear).But do not shift the transfer case to the N (Neutral) position. Leave the transfer case in the 2 Wheel, 4 Highor 4 Low position.
