By moving the gearshift lever from the D(Drive) position to the M (Manual) positionyou may now manually select the gear youdesire. Only the current gear will bedisplayed. Press the + button or the –button to upshift or downshift. If the –button is pressed at a vehicle speed that
would cause an engine overspeed, therequested gear will flash then disappearand the transmission will remain in thecurrent gear.
Recommended shift speeds
Upshift according to the following chart:
Upshifts when accelerating (recommended for best fuel economy)
Diesel enginesGasoline enginesShift from:
12 mph (19 km/h)15 mph (24 km/h)1 – 2
19 mph (31 km/h)25 mph (40 km/h)2 – 3
26 mph (42 km/h)40 mph (64 km/h)3 – 4
34 mph (55 km/h)45 mph (72 km/h)4 – 5
46 mph (74 km/h)50 mph (80 km/h)5 – 6
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 the engine willnot be damaged from over-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 ifexcessive engine revving is held withoutshifting.
Automatic Transmission AdaptiveLearning
This feature is designed to increasedurability and provide consistent shift feelover the life of the vehicle. A new vehicleor transmission may have firm shifts, softshifts or both. This operation is considerednormal and will not affect function ordurability of the transmission. Over time,the adaptive learning process will fullyupdate transmission operation.Additionally, whenever the battery isdisconnected or a new battery installed,the strategy must be relearned.

Do not use a hitch that eitherclamps onto the bumper orattaches to the axle. You mustdistribute the load in your trailerso that 10-15% for conventionaltowing or 15-25% for fifth wheeltowing of the total weight of thetrailer is on the tongue.
Weight-distributing Hitches
WARNING
Do not adjust aweight-distributing hitch toany position where the rearbumper of the vehicle is higherthan it was before attaching thetrailer. Doing so will defeat thefunction of the weight-distributinghitch, which may causeunpredictable handling, and could
result in serious personal injury.
When hooking-up a trailer using aweight-distributing hitch, alwaysuse the following procedure:
1. Park the loaded vehicle,without the trailer, on a levelsurface.
2.Measure the height to the topof your vehicle's front wheelopening on the fender. This isH1.
3.Attach the loaded trailer toyour vehicle without theweight-distributing barsconnected.
4.Measure the height to the topof your vehicle's front wheelopening on the fender a secondtime. This is H2.
5.Install and adjust the tensionin the weight-distributing barsso that the height of yourvehicle's front wheel openingon the fender is approximatelyhalfway between H1 and H2.
6.Check that the trailer is level orslightly nose down toward yourvehicle. If not, adjust the ballheight accordingly and repeatSteps 2-6.
Once the trailer is level or slightlynose down toward the vehicle:
•Lock the bar tension adjusterin place.
•Check that the trailer tonguesecurely attaches and locksonto the hitch.
•Install safety chains, lighting,and trailer brake controls asrequired by law or the trailermanufacturer.

When backing down a rampduring boat launching or retrieval:
•Do not allow the static waterlevel to rise above the bottomedge of the rear bumper.
•Do not allow waves to breakhigher than 6 inches (15centimeters) above the bottomedge of the rear bumper.
Exceeding these limits may allowwater to enter vehiclecomponents:
•Causing internal damage to thecomponents.
•Affecting driveability,emissions, and reliability.
Replace the rear axle lubricantanytime the rear axle has beensubmerged in water. Water mayhave contaminated the rear axlelubricant, which is not normallychecked or changed unless a leakis suspected or other axle repair isrequired.
TOWING POINTS
WARNINGS
Using recovery hooks is dangerousand should only be done by a personfamiliar with proper vehicle recoverysafety practices. Improper use of recoveryhooks may cause hook failure or separationfrom the vehicle and could result in seriousinjury or death.
Always slowly remove the slack fromthe recovery strap prior to pulling.Failure to do so can introducesignificantly higher loads which can causethe recovery hooks to break off, or therecovery strap to fail which can causeserious injury or death.
Never link two straps together witha clevis pin. These heavy metalobjects could become projectiles ifthe strap breaks and can cause seriousinjury or death.
Your vehicle comes equipped withframe-mounted front recovery hooks.These hooks should never have a loadapplied to them greater than the grossvehicle weight rating of your vehicle.
Before using recovery hooks:
•Make sure all attaching points aresecure and capable of withstandingthe applied load.
•Never use chains, cables or tow strapswith metal hook ends.
•Only use recovery straps that have aminimum breaking strength two tothree times the gross vehicle weight ofthe stuck vehicle.
•Make sure the recovery strap is in goodcondition and free of visible cuts, tearsor damage.

•Transmissions give their best fueleconomy when operated in the topcruise gear and with steady pressureon the gas pedal.
•Four-wheel-drive operation (ifequipped) is less fuel efficient thantwo-wheel-drive operation.
•Close the windows for high-speeddriving.
DRIVING THROUGH WATER
Note:Driving through deep water abovethe recommended levels can cause vehicledamage.
If driving through deep or standing wateris unavoidable, proceed very slowly. Neverdrive through water that is higher than thebottom of the wheel rims (for cars) or thebottom of the hubs (for trucks).
When driving through water, traction orbrake capability may be limited. Also,water may enter your engine’s air intakeand severely damage your engine or yourvehicle may stall.
Once through the water, always dry thebrakes by moving your vehicle slowly whileapplying light pressure on the brake pedal.Wet brakes do not stop the vehicle asquickly as dry brakes.
FLOOR MATS

Always use floor mats that aredesigned to fit the foot well of yourvehicle, leaving the pedal areaunobstructed, and which can be firmlysecured to retention posts so that theycannot slip out of position and interferewith the pedals or impair safe operation ofyour vehicle in other ways.
Incorrectly fitted floor mats cancause the accelerator pedal tobecome stuck in the open position.This can cause loss of vehicle control.
Always correctly install the floormats to the retention posts so thatthey cannot slip out of position orobstruct pedal operation.
Do not place unsecured floor matsor any other covering in the foot well.
Do not place additional floor matsor any other covering on top of theoriginal floor mats. This will reducethe pedal clearance and interfere with thepedal operation.
Do not allow objects to fall orbecome trapped under the pedals ofyour vehicle. This can cause loss ofvehicle control.
Carry out regular inspections to makesure the floor mats are secure.
