AUTOMATIC TRANSMISSION
WARNING: Apply the parkingbrake, shift into park (P), switch theignition off and remove the key beforeyou leave your vehicle. Failure to followthis instruction could result in personalinjury or death.
WARNING: Do not apply the brakepedal and accelerator pedalsimultaneously. Applying both pedalssimultaneously for more than a fewseconds limits vehicle performance,which may result in difficulty maintainingspeed in traffic and could lead to seriousinjury.
Understanding the Shift Positionsof Your Automatic Transmission
6-Speed Transmissions
10-Speed Transmissions
Putting your vehicle in or out of gear:
1.Fully press the brake pedal.
2.Move the gearshift lever into thepreferred gear.
3.When you finish driving, come to acomplete stop.
4.Move the gearshift lever and securelylatch it in park (P) or neutral (N).
The instrument cluster displays the currentgear.
Park (P)
If your transmission has a park (P) position,this position locks the transmission andprevents the rear wheels from turning.
Reverse (R)
With the gearshift lever in reverse (R), yourvehicle moves backward. Always come toa complete stop before shifting into andout of reverse (R).
Neutral (N)
With the gearshift lever in neutral (N), youcan start your vehicle and it is free to roll.Hold the brake pedal down when in thisposition.
Drive (D)
Drive (D) is the normal driving position forthe best fuel economy. The overdrivefunction allows automatic upshifts anddownshifts through gears one through six.
Manual (M)
With the gearshift lever in manual (M), thedriver can change gears up or down aspreferred. By moving the gearshift leverfrom drive (D) to manual (M), you nowhave control of selecting the gear youprefer using the buttons on the shift lever.See Understanding Your SelectShiftAutomatic™ Transmission later in thissection.

WHAT IS THE PNEUMATIC
LOCKING DIFFERENTIAL
The pneumatic locking differential can lockor unlock the differential when the vehicleis moving or stopped. The differential lockprovides full power to both wheels whenextra traction is required.
HOW DOES THE PNEUMATIC
LOCKING DIFFERENTIAL
WORK
If your vehicle is equipped with apneumatic locking differential:
•Power is transmitted to the oppositewheel should one of the wheels beginto slip.
•Raise both wheels off the ground if itbecomes necessary to operate onewheel with the vehicle stationary.
The differential can be locked or unlockedwhen the vehicle is moving at a constantspeed of less than 25 mph (40 km/h) andwhile the wheels are not slipping. Do notlock the differential when the vehicle istraveling down steep grades and tractionis minimal.
Note:Do not use the differential lock atvehicle speeds above 25 mph (40 km/h).
When the differential is locked, thevehicle’s turning radius increases causingundersteer.
The differential lock and differential locklight automatically disengage at speedsabove 25 mph (40 km/h). The differentiallock remains off until the vehicle isrestarted or the differential lock switch isturned off then back on.
PNEUMATIC LOCKING
DIFFERENTIAL PRECAUTIONS
WARNING: Exceeding any vehicleweight rating can adversely affect theperformance and handling of yourvehicle, cause vehicle damage and canresult in the loss of control of yourvehicle, serious personal injury or death.
WARNING: Failure to raise all drivewheels with this type of differential couldcause the vehicle to move unexpectedly,resulting in property damage, personalinjury or death.
WARNING: Sudden accelerationon slippery surfaces could cause thewheels to spin, the vehicle to turnsideways on a crowned road surface orin a turn, possibly resulting in loss ofvehicle control and personal injury.
SWITCHING THE PNEUMATIC
LOCKING DIFFERENTIAL ON
AND OFF
