Active Fuel Management™
Vehicles with V8 engines may have Active FuelManagement™. This system allows the engine tooperate on either all or half of its cylinders, dependingon the driving conditions.
When less power is required, such as cruising at aconstant vehicle speed, the system will operate in thehalf cylinder mode, allowing the vehicle to achievebetter fuel economy. When greater power demands arerequired, such as accelerating from a stop, passing,or merging onto a freeway, the system will maintainfull-cylinder operation.
If the vehicle has an Active Fuel Management™indicator, seeDIC Operation and Displaysonpage 4!41for more information on using this display.
Automatic Transmission Operation
If the vehicle is a Two-mode Hybrid, see the Two-modeHybrid manual for more information.
The vehicle has a Hydra-Matic®6L80 automatictransmission, and has an electronic shift positionindicator within the instrument panel cluster.The electronic shift position indicator displays whenthe shift lever is moved out of P (Park).
There are several different positions for the shift lever.
P (Park) :This position locks the rear wheels. It is thebest position to use when you start the engine becausethe vehicle cannot move easily.
3-32

When parked on a hill, especially when the vehicle hasa heavy load, you may notice an increase in the effortto shift out of P (Park). See Torque Lock (AutomaticTransmission) underShifting Into Parkon page 3!39for more information.
{WARNING:
It is dangerous to get out of the vehicle if the shift
lever is not fully in P (Park) with the parking brake
firmly set. The vehicle can roll.
Do not leave the vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure the
vehicle will not move, even when you are on fairly
level ground, always set the parking brake and
move the shift lever to P (Park). SeeShifting Into
Parkon page 3!39. If you are pulling a trailer,
seeTowing a Trailer on page 6!42.
R (Reverse) :Use this gear to back up.
Notice:Shifting to R (Reverse) while the vehicle ismoving forward could damage the transmission.The repairs would not be covered by the vehiclewarranty. Shift to R (Reverse) only after the vehicleis stopped.
To rock the vehicle back and forth to get out of snow,ice, or sand without damaging the transmission, seeIfYour Vehicle is Stuck in Sand, Mud, Ice, or Snowonpage 6!30.

Shifting Into Park
{WARNING:
It can be dangerous to get out of the vehicle if the
shift lever is not fully in P (Park) with the parking
brake firmly set. The vehicle can roll. If you have
left the engine running, the vehicle can move
suddenly. You or others could be injured. To be
sure the vehicle will not move, even when you are
on fairly level ground, use the steps that follow.
If you are pulling a trailer, seeTowing a Traileron
page 6!42.
1. Hold the brake pedal down, then set theparking brake.
2. Move the shift lever into the P (Park) position bypulling the shift lever toward you and moving it upas far as it will go.
3. Turn the ignition key to LOCK/OFF.
4. Remove the key and take it with you. If you canleave the vehicle with the ignition key in your hand,the vehicle is in P (Park).
Leaving the Vehicle With the Engine
Running
{WARNING:
It can be dangerous to leave the vehicle with the
engine running. The vehicle could move suddenly
if the shift lever is not fully in P (Park) with the
parking brake firmly set. And, if you leave the
vehicle with the engine running, it could overheat
and even catch fire. You or others could be
injured. Do not leave the vehicle with the
engine running.
If you have to leave the vehicle with the engine running,be sure the vehicle is in P (Park) and the parking brakeis firmly set. After the shift lever is moved into P (Park),hold the regular brake pedal down. Then, see if you canmove the shift lever away from P (Park) without firstpulling it toward you. If you can, it means that the shiftlever was not fully locked into P (Park).

Torque Lock
If you are parking on a hill and you do not shift thetransmission into P (Park) properly, the weight of thevehicle can put too much force on the parking pawl inthe transmission. It might be difficult to pull the shiftlever out of P (Park). This is called torque lock. Toprevent torque lock, set the parking brake and then shiftinto P (Park) properly before you leave the driver seat.To find out how, seeShifting Into Park on page 3!39.
When you are ready to drive, move the shift lever out ofP (Park) before releasing the parking brake.
If torque lock does occur, you might need to haveanother vehicle push yours a little uphill to take some ofthe pressure from the parking pawl in the transmission.Then you should be able to pull the shift lever outof P (Park).
Shifting Out of Park
This vehicle is equipped with an electronic shift lockrelease system. The shift lock release is designed to:
.Prevent ignition key removal unless the shift leveris in P (Park) with the shift lever button fullyreleased, and
.Prevent movement of the shift lever out ofP (Park), unless the ignition is in ON/RUN orACC/ACCESSORY and the regular brake pedalis applied.
The shift lock release is always functional exceptin the case of an uncharged or low voltage(less than 9 volt) battery.
If the vehicle has an uncharged battery or a batterywith low voltage, try charging or jump starting thebattery. SeeJump Startingon page 7!44formore information.
To shift out of P (Park) use the following:
1. Apply the brake pedal.
2. Move the shift lever to the desired position.
If you still are unable to shift out of P (Park):
1. Ease the pressure on the shift lever.
2. While holding down the brake pedal, press theshift lever all the way into P (Park).
3. Move the shift lever to the desired position.
If you are still having a problem shifting, then have thevehicle serviced soon.
