Starting and Stopping the Engine

WARNING: Do not use your heaterwith ungrounded electrical systems ortwo-pronged adapters. There is a risk ofelectrical shock.
WARNING: Do not fully close thehood, or allow it to drop under its ownweight when using the engine blockheater. This could damage the power cableand may cause an electrical short resultingin fire, injury and property damage.
Note:The heater is most effective whenoutdoor temperatures are below 0°F (-18°C).
The heater acts as a starting aid by warmingthe engine coolant. This allows the climatecontrol system to respond quickly. Theequipment includes a heater element(installed in the engine block) and a wireharness. You can connect the system to agrounded 120-volt AC electrical source.
We recommend that you do the following fora safe and correct operation:
•Use a 16-gauge outdoor extension cordthat is product certified by Underwriter’sLaboratory (UL) or Canadian StandardsAssociation (CSA). This extension cordmust be suitable for use outdoors, in coldtemperatures, and be clearly markedSuitable for Use with OutdoorAppliances. Do not use an indoorextension cord outdoors. This couldresult in an electric shock or become afire hazard.
•Use as short an extension cord aspossible.
•Do not use multiple extension cords.
•Make sure that when in operation, theextension cord plug and heater cord plugconnections are free and clear of water.This could cause an electric shock or fire.
•Make sure your vehicle is parked in aclean area, clear of combustibles.
•Make sure the heater, heater cord andextension cord are firmly connected.
•Check for heat anywhere in the electricalhookup once the system has beenoperating for approximately 30 minutes.
•Make sure the system is unplugged andproperly stowed before starting anddriving your vehicle. Make sure theprotective cover seals the prongs of theblock heater cord plug when not in use.
•Make sure the heater system is checkedfor proper operation before winter.
Using the Engine Block Heater
Make sure the receptacle terminals are cleanand dry prior to use. Clean them with a drycloth if necessary.
The heater uses 0.4 to 1.0 kilowatt-hours ofenergy per hour of use. The system does nothave a thermostat. It achieves maximumtemperature after approximately three hoursof operation. Using the heater longer thanthree hours does not improve systemperformance and unnecessarily useselectricity.

Note:The AdvanceTrac system can takecontrol of the transfer case clutch anddisable it during driving maneuvers whennecessary.
Your vehicle engages 4X4 modes based onthe currently selected Drive Mode. SeeDrive Mode Control (page 285).
Note:The information display could showmessages during 4WD operation. SeeInformation Messages (page 124).
2H - 4X2
2H turns on when you select NORMAL orCONSERVE. Power is delivered to the rearwheels only. This mode is appropriate fornormal on-road driving on dry pavement andprovides the best fuel economy.
4A - 4X4 Auto
4A turns on when you select EXCITE,NORMAL 4x4 AUTO or SLIPPERY. Itprovides electronically controlled four-wheeldrive with power delivered to all four wheels,as required, for increased traction. 4A iscalibrated in conjunction with Drive Mode.4A in EXCITE is less aggressively tuned andis appropriate for dry road surfaces. 4A inNORMAL 4x4 AUTO is appropriate for allon-road driving conditions, such as dry roadsurfaces, wet pavement, light snow or gravel.4A in SLIPPERY is more aggressively tunedand is appropriate for slippery surfaces, suchas light snow or gravel.
4H - 4X4 High
4H turns on when you select DEEPCONDITIONS. It provides electronicallylocked four-wheel drive power to both thefront and rear wheels for use in off-road orwinter conditions such as deep snow, sandor mud. This mode is not for use on drypavement.
4L - 4X4 Low
4L turns on when you select SLOW CLIMB.It provides electronically locked four-wheeldrive power to both the front and rear wheelsfor use on low traction surfaces, but does sowith additional gearing for increased torquemultiplication. Intended only for off-roadapplications such as deep sand, steepgrades or pulling heavy objects. 4L does notengage when your vehicle is moving above3 mph (5 km/h); this is normal and should beno reason for concern.
Shifting Between 4WD System Modes
Note:Momentarily releasing the acceleratorpedal when a shift in progress messagedisplays improves engagement anddisengagement performance.
Note:Do not perform this operation if therear wheels are slipping.
Note:You may hear some noise as thesystem shifts or engages; this is normal.

Shifting To or From 4L - 4X4 LOW
Note:4L mode is not intended for use on drypavement.
1. Bring the vehicle to a rolling speed of3 mph (5 km/h) or less.
2. Place the gearshift in neutral (N).
3. Rotate the drive mode knob to desiredmode.
The information display shows a messageindicating a 4X4 shift is in progress. Theinformation display shows the system modeselected. If any of the previous shiftconditions are not present, the shift does notoccur and the information display shows theinformation guiding the driver through theproper shifting procedures. If the previousconditions are not satisfied in 30 seconds,the system reverts back to the previous 4WDmode or drive mode.
If Shift Delayed Pull Forward displays in theinformation display, transfer case gear toothblockage is present. To alleviate thiscondition, place the transmission in a forwardgear, move the vehicle forwardapproximately 5 ft (2 m), and shift thetransmission back to neutral (N) to allow thetransfer case to complete the range shift.
Operating 4WD Vehicles With Spareor Mismatched Tires
On four-wheel drive vehicles, the size of thespare tire can affect the 4X4 system. If thereis a significant difference between the sizeof the spare tire and the remaining tires, youmay have limited four-wheel drivefunctionality.
When driving with the full-size dissimilarspare wheel and tire assembly, it isrecommended that you do not:
•Exceed 50 mph (80 km/h) with a 4WDmode turned on.
•Turn on a 4WD mode unless the vehicleis stationary.
•Use a 4WD mode on dry pavement.
Use of a dissimilar spare wheel and tireassembly may lead to impairment of thefollowing:
•Comfort and noise.
•Winter weather driving capability.
•Wet driving capability.
•Four-wheel drive capability.
How Your Vehicle Differs From OtherVehicles
WARNING: Vehicles with a highercenter of gravity (utility and four-wheeldrive vehicles) handle differently thanvehicles with a lower center of gravity(passenger cars). Avoid sharp turns,excessive speed and abrupt steering inthese vehicles. Failure to drive cautiouslyincreases the risk of losing control of yourvehicle, vehicle rollover, personal injuryand death.

Four-Wheel Drive (If Equipped)

Truck and utility vehicles can differ fromsome other vehicles. Your vehicle may behigher to allow it to travel over rough terrainwithout getting hung up or damagingunderbody components.
The differences that make your vehicle soversatile also make it handle differently thanan ordinary passenger car.
Maintain steering wheel control at all times,especially in rough terrain. Since suddenchanges in terrain can result in abruptsteering wheel motion, make sure you gripthe steering wheel from the outside. Do notgrip the spokes.
Drive cautiously to avoid vehicle damagefrom concealed objects such as rocks andstumps.
You should either know the terrain orexamine maps of the area before driving.Map out your route before driving in the area.To maintain steering and braking control ofyour vehicle, you must have all four wheelson the ground and they must be rolling, notsliding or spinning.
Driving Off-Road With Truck and UtilityVehicles
Note:On some models, the initial shift fromtwo-wheel drive to four-wheel drive whenthe vehicle is moving can cause somemomentary clunk and ratcheting sounds.This is the front drivetrain coming up tospeed and the automatic locking hubsengaging and is not cause for concern.
Note:Your vehicle may have a front air dam.Due to low ground clearance, you candamage it when taking your vehicle off-road.You can take the air dam off by removingthe bolts that secure it.
Four-wheel drive vehicles are speciallyequipped for driving on sand, snow, mud andrough terrain and have operatingcharacteristics that are somewhat differentfrom conventional vehicles, both on and offthe road.
Power is supplied to all four wheels througha transfer case. On four-wheel drive vehicles,the transfer case allows you to utilizedifferent 4X4 modes when necessary.Information on transfer case operation andshifting procedures can be found in this
chapter and the Driving Aids chapter.Information on transfer case maintenancecan be found in the Maintenance chapter.You should become thoroughly familiar withthis information before you operate yourvehicle.
Four-wheel drive, when you select a4X4-capable drive mode, it uses all fourwheels to power the vehicle. This increasestraction, enabling you to drive over terrainand road conditions that a conventionaltwo-wheel drive vehicle cannot.

Four-Wheel Drive (If Equipped)

When climbing a steep slope or hill, start ina lower gear rather than downshifting to alower gear from a higher gear once theascent has started. This reduces strain onthe engine and the possibility of stalling.
If your vehicle stalls, do not try to turn aroundbecause this could cause vehicle roll over.It is better to reverse back to a safe location.
Apply just enough power to the wheels toclimb the hill. Too much power causes thetires to slip, spin or lose traction, resulting inloss of vehicle control.
Descend a hill in the same gear you woulduse to climb up the hill to avoid excessivebrake application and brake overheating. Donot descend in neutral. Disengage overdriveor move the transmission selector lever to alower gear. When descending a steep hill,avoid sudden hard braking as you could losecontrol. The front wheels have to be turningin order to steer your vehicle.
If your vehicle has anti-lock brakes, apply thebrakes steadily. Do not pump the brakes.
Driving on Snow and Ice
WARNING: If you are driving inslippery conditions that require tire chainsor cables, then it is critical that you drivecautiously. Keep speeds down, allow forlonger stopping distances and avoidaggressive steering to reduce the chancesof a loss of vehicle control which can leadto serious injury or death. If the rear endof your vehicle slides while cornering, steerin the direction of the slide until you regaincontrol of your vehicle.
Note:Excessive tire slippage can causetransmission damage.
Four-wheel drive vehicles have advantagesover two-wheel drive vehicles in snow andice but can skid like any other vehicle.Should you start to slide when driving onsnowy or icy roads, turn the steering wheelin the direction of the slide until you regaincontrol.
Avoid sudden applications of power andquick changes of direction on snow and ice.Apply the accelerator slowly and steadilywhen starting from a full stop.
Avoid sudden braking. Although a four-wheeldrive vehicle may accelerate better than atwo-wheel drive vehicle in snow and ice, itdoes not stop any faster as braking occursat all four wheels. Do not becomeoverconfident in any road condition.
Make sure you allow sufficient distancebetween you and other vehicles for stopping.Drive slower than usual and consider usingone of the lower gears. In emergencystopping situations, apply the brake steadily.Do not pump the brake pedal. See Hints onDriving With Anti-Lock Brakes (page 226).

LIMITED SLIP DIFFERENTIAL (IF
EQUIPPED)
The Electronic Limited Slip Differential (eLSD)system directs torque, enabling the vehicleto drive over terrain and road conditions thata conventional axle cannot. The system isactive at all times and requires no input fromthe driver.
Note:If your vehicle is not at optimaloperating conditions or a system fault ispresent, a warning may be displayed in theinstrument cluster. Depending on thewarning, your vehicle may need to beserviced. For more information regarding thesystem information messages, SeeInformation Messages (page 124).
Locking Function (If Equipped)
The lock button engages ‘lockermode’.
With the locker engaged, the systemelectronically locks the differential causingboth half shafts to turn at the same rate. Thisincreases traction during off road events.
The locker mode may automaticallydisengage based on certain conditions suchas vehicle speed. When engaged, a telltalein the instrument cluster will illuminate amberand the switch button will be illuminated.When the speed is exceeded the telltale willturn gray, the locker will be disengaged andbe in standby mode until the speedconditions are met. If the eLSD system isfaulted and the locker cannot engage, awarning message will be displayed in theinstrument cluster and the switch button willflash.
Spare Tire
If your vehicle is equipped with an ElectronicLimited Slip Differential, a spare tire of adifferent size than the tire provided, shouldnot be used. If a spare tire is installed, amessage may appear, indicating the systemhas disabled automatically or reducedfunction to prevent system overheat anddamage. It is recommended to reinstall therepaired or replaced road tire as soon aspossible. When the road tire is replaced, thesystem will resume normal operation on thenext key cycle.
Trailer Towing
The Electronic Limited Slip Differentialenhances vehicle stability during trailer towoperation. During high demand traileringevents (such as steep grades, high speedsor with a spare tire), the system may providea warning in the instrument cluster andreduce function or enter a temporarilydisabled state. To resume normal function,stop the vehicle in a safe location and allowthe unit to adequately cool. Once the systemhas reached normal operating temperatures,system function will be restored and theElectronic Limited Slip Differential Restoredmessage will be displayed.
