•The gearshift lever must be in P (Park)or N (Neutral) in order for the starterto operate.
•Try operating the starter switch severaltimes. This operation may cleanpotentially corroded contacts or makethe switch temporarily operable untilyou can reach the dealer.
•If all electrical connections are tightand you need assistance to start, SeeJump Starting the Vehicle (page 190).
If engine cranks but won’t start
Prolonged starter cranking (in excess of 10seconds) could cause damage to thestarter motor or the high-pressure fuelpump.
•Check the fuel gauge. You may be outof fuel. If the gauge shows that thereis fuel in the tank, the trouble may bein the electrical system or the fuelsystem. If equipped with an auxiliarytank, be sure that the tank controlswitch is set for the tank with fuel andnot on an empty tank.
•Leaving your ignition key turned to onfor over two minutes without startingmay make starting difficult becausethe glow plugs will cease activation.Reset the system by turning the ignitionkey to off and then back to on again.
Note:If the system is out of fuel and theengine will not start, do not continuecranking the engine. Continued cranking candamage the high-pressure fuel pump.
If the engine runs hot
The following could cause the engine tooverheat:
•Lack of coolant
•Dirty cooling system.
•Plugged radiator fins, A/C condenserand/or oil cooler
•Malfunctioning fan drive
•Driving with frozen coolant
•Sticking thermostat
•Overloading or pulling heavy trailersduring hot weather
•Grill or radiator air blockage
•Slipping or missing drive belt
•Plugged or very dirty air filter
If fuses burn out
WARNING: Replacement fuses andcircuit breakers must always be thesame rating as the original equipmentshown. Never replace a fuse or circuitbreaker with one of a higher rating.Higher rated fuses or circuit breakerscould allow circuit overloading in theevent of a circuit malfunction, resultingin severe vehicle damage or personalinjury due to fire.
Burned-out or blown fuses usually indicatean electrical short-circuit, although a fusemay occasionally burn out from vibration.Insert a second fuse. If this fuseimmediately burns out and you cannotlocate the cause, return your vehicle toyour dealer for a circuit check. SeeChanging a Fuse (page 211).
Selective catalytic reduction systemspeed limit and Idle-only modes
If the vehicle’s speed is limited or in anidle-only mode, the selective catalyticreduction system may be limiting thevehicle’s functions due to low orcontaminated DEF. Check the DEF. SeeSelective Catalytic Reductant System(page 120).

Automatic Transmission AdaptiveLearning
This feature could increase durability andprovide consistent shift feel over the lifeof your vehicle. A new vehicle ortransmission may have firm shifts, softshifts, or both. This is normal and does notaffect the function or durability of thetransmission. Over time, the adaptivelearning process fully updates transmissionoperation.
Brake-Shift Interlock
WARNING: Do not drive yourvehicle until you verify that thestoplamps are working.
WARNING: When doing thisprocedure, you need to take thetransmission out of park (P) whichmeans your vehicle can roll freely. Toavoid unwanted vehicle movement,apply the parking brake prior to doingthis procedure. Use wheel chocks ifappropriate.
WARNING: If the parking brake isfully released, but the brake warninglamp remains illuminated, the brakesmay not be working properly. Have yourvehicle checked as soon as possible.
Your vehicle has a brake-shift interlockfeature that prevents the gearshift leverfrom moving from park (P) when youswitch the ignition on but have not pressedthe brake pedal.
If you cannot move the gearshift lever outof the park (P) position with the ignition inthe on position and the brake pedalpressed, a malfunction could haveoccurred. It is possible that a fuse hasblown, or your vehicle’s brake lamps arenot operating properly. See FuseSpecification Chart (page 202).
If you do not have a blown fuse and thebrake lamps are working properly, thefollowing procedure allows you to movethe gearshift lever from park (P):
1.Apply the parking brake. Switch theignition key to off, then remove the key.
2.Move the steering column to the fulldown and full rearward position,toward the driver seat.
3.Remove the gearshift lever boot.
4.Place your fingers into the hole whereyou removed the gearshift lever bootand pull the top half of the shroud upand forward to separate it from thelower half of the shroud. There is ahinge at the forward edge of the top ofthe shroud. Roll the top half of theshroud upward on the hinge point, thenpull straight rearward toward the driverseat to remove.
5.Remove the top half of the shroud.
6.Remove the three fasteners under thecolumn that secure the lower shroudhalf to the column.
7.Pull the lock lever into the full unlockedposition and remove the lower shroudcover by pulling the lever handlethrough the slot in the cover.
8.Apply the brake. Gently lift the overridedisk and move the gearshift lever intoneutral (N).

TOWING A TRAILER
WARNING: Do not exceedthe GVWR or the GAWRspecified on the certificationlabel.
WARNING: Towing trailersbeyond the maximumrecommended gross trailerweight exceeds the limit of thevehicle and could result in enginedamage, transmission damage,structural damage, loss ofvehicle control, vehicle rolloverand personal injury.
Your vehicle may have electricalitems, such as fuses or relays,related to towing. See Fuses(page 202).
Your vehicle's load capacitydesignation is by weight, not byvolume, so you cannot necessarilyuse all available space whenloading a vehicle.
Towing a trailer places an extraload on your vehicle's engine,transmission, axle, brakes, tiresand suspension. Inspect thesecomponents periodically during,and after, any towing operation.
Load Placement
To help minimize how trailermovement affects your vehiclewhen driving:
•Load the heaviest items closestto the trailer floor.
•Load the heaviest itemscentered between the left andright side trailer tires.
•Load the heaviest items abovethe trailer axles or just slightlyforward toward the trailertongue. Do not allow the finaltrailer tongue weight to goabove or below 10-15% of theloaded trailer weight.
When driving with a trailer orpayload, a slight takeoff vibrationor shudder may be present due tothe increased payload weight.Additional information regardingproper trailer loading and settingyour vehicle up for towing islocated in another chapter of thismanual. See Load Limit (page178).

WARNING: Do not attach the endof the positive cable to the studs orL-shaped eyelet located above thepositive (+) terminal of your vehicle’sbattery. High current may flow throughand cause damage to the fuses.
WARNING: Do not connect the endof the second cable to the negative (-)terminal of the battery to be jumped. Aspark may cause an explosion of thegases that surround the battery.
Note:In the illustration, the bottom vehiclerepresents the booster vehicle.
1.Connect the positive (+) jumper cableto the positive (+) terminal of thedischarged battery.
2.Connect the other end of the positive(+) cable to the positive (+) terminalof the booster vehicle battery.
3.Connect the negative (-) cable to thenegative (-) terminal of the boostervehicle battery.
4.Make the final connection of thenegative (-) cable to an exposed metalpart of the stalled vehicle's engine,away from the battery and the fuelinjection system, or connect thenegative (-) cable to a groundconnection point if available.
Note:There is an optional jump startterminal underneath the passenger sideentry steps.
Jump Starting
1.Start the engine of the booster vehicleand rev the engine moderately, or pressthe accelerator gently to keep yourengine speed between 2000 and 3000RPM, as shown in your tachometer.
2.Start the engine of the disabled vehicle.
3.Once the disabled vehicle has beenstarted, run both vehicle engines for anadditional three minutes beforedisconnecting the jumper cables.
