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.

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.

GENERAL INFORMATION
Note: Occasional brake noise is normal. Ifa metal-to-metal, continuous grinding orcontinuous squeal sound is present, thebrake linings may be worn-out. Have thesystem checked as soon as possible. If thevehicle has continuous vibration or shudderin the steering wheel while braking, have thesystem checked as soon as possible.
All standard equipment brakes areself-adjusting. Automatic adjustment,when required, occurs whenever you applyand release the brakes during forward orreverse operation.
Know the required stopping distances forall driving conditions you may encounter.For longer brake lining life, take fulladvantage of engine braking power whencoming to a stop.
Wet brakes result in reduced brakingefficiency. Gently press the brake pedal afew times when driving from a car wash orstanding water to dry the brakes.
If the brakes do not grip well:
•Check brake adjustment.
•Check the brake linings for excessivewear.
•Check the system air pressure onvehicles with air brakes.
•Let the brakes cool if you have beenusing them excessively, as in mountaindriving or after several fast, high-speedstops.
•If you have been driving through deepwater, gently apply the brakes severaltimes while your vehicle is movingslowly.
Brake Over Accelerator
In the event the accelerator pedalbecomes stuck or entrapped, apply steadyand firm pressure to the brake pedal toslow the vehicle and reduce engine power.If you experience this condition, apply thebrakes and bring your vehicle to a safestop. Move the transmission to park (P),switch the engine off and apply the parkingbrake. Inspect the accelerator pedal forany interference. If none are found and thecondition persists, have your vehicle towedto the nearest authorized dealer
Anti-lock Brake System
This system helps you maintain steeringcontrol during emergency stops by keepingthe brakes from locking.
If the light does not illuminateduring start up, remains on orflashes, the system may bedisabled. It also momentarily illuminateswhen you switch the ignition on to confirmthe lamp is functional. If it does notilluminate when you switch the ignition on,or begins to flash at any time, have thesystem checked.
If you connect a PLC trailer withthe ignition on, the trailer ABSlight also illuminates. If the lightfails to illuminate, if it remains on after youstart the vehicle or continues to flash, havethe system serviced immediately.
See Warning Lamps and Indicators(page 67).

If the system is disabled, normalbraking is still effective. If thebrake warning lamp illuminateswith the parking brake released, have thesystem checked immediately. It alsomomentarily illuminates when you switchthe ignition on to confirm the lamp isfunctional. If it does not illuminate whenyou switch the ignition on, or begins toflash at any time, have the systemchecked.
HINTS ON DRIVING WITH
ANTI-LOCK BRAKES
The anti-lock brake system does noteliminate the risks when:
•You drive too closely to the vehicle infront of you.
•Your vehicle is hydroplaning.
•You take corners too fast.
•The road surface is poor.
Note: If the system activates, the brakepedal could pulse and may travel further.Maintain pressure on the brake pedal. Youmay also hear a noise from the system. Thisis normal.
PARKING BRAKE
Hydraulic Brakes (If Equipped)
WARNING: Always set the parkingbrake and leave your vehicle with thetransmission in park (P).
WARNING: This control is forparking only. Do not leave the vehicleunattended after setting the parkingbrake without placing the transmissionin park (P). We recommend using wheelchocks for hilly or off-roadcircumstances.
WARNING: Unexpected andpossibly sudden vehicle movement mayoccur if you do not take theseprecautions.
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.
Apply the parking brake whenever thevehicle is parked. To set the parking brake,pull the handle up until it snaps into thelocked position.
When the parking brake is out ofadjustment, seek service immediately.
The parking brake warning lampin the instrument clusterilluminates, and remainsilluminated (when you switch on theignition), until you release the parkingbrake.

Push the palm release lever (A) on theparking brake handle (B) and push downas far as possible to release the brake.Driving with the parking brake on causesthe brakes to wear out quickly and reducesfuel economy.
We recommend you not use the parkingbrake to stop a moving vehicle. However,if the normal brakes fail, you can use theparking brake to stop your vehicle in anemergency. Since the parking brake onlyapplies retardation to the rear wheels, thevehicle's stopping distance increasesgreatly and the handling of your vehicle isadversely affected.
Releasing Spring Manually
WARNING: Do not attempt todisassemble the parking brake airchamber under any circumstances asthis may cause serious injury.
WARNING: Block the wheels tohelp prevent the vehicle from moving.
WARNING: Unexpected andpossibly sudden vehicle movement mayoccur if you do not take theseprecautions.
If you release hydraulic pressure from thespring brake chamber, the power springapplies the brake. If the hydraulic pressurecan be re-established, you must releasethe spring brake in order to move yourvehicle.
Air Brakes (If Equipped)
WARNING: This control is forparking only. Do not leave the vehicleunattended after setting the parkingbrake without placing the transmissionin park (P). We recommend using wheelchocks for hilly or off-roadcircumstances.
If the service brakes fail to operate whileyour vehicle is moving, you can make anemergency stop with the parking brake.Since the parking brake only appliesstopping power to the rear wheels, yourvehicle’s stopping distance greatlyincreases and the handling of your vehicleis adversely affected. Make repairsimmediately to an inoperative air brakesystem circuit.
Pull the yellow, dash-mounted parkingbrake knob to apply the parking brake.
The parking brake lightilluminates and remainsilluminated (when you switchthe ignition to the on position) until yourelease the parking brake.

In these cases, the system may brake lateor unexpectedly. You should stay alert andtake action when necessary.
If something hits the front end of yourvehicle or damage occurs, theradar-sensing zone may change. This couldcause missed or false vehicle detection.
Optimal system performance requires aclear view of the road by thewindshield-mounted camera.
Optimal performance may not occur if:
•The camera is blocked.
•There is poor visibility or lightingconditions.
•There are bad weather conditions.
System Not Available
Conditions that can cause the system todeactivate or prevent the system fromactivating when requested include:
•A blocked sensor.
•High brake temperature.
•A failure in the system or a relatedsystem.
Blocked Sensor
A message displays if something obstructsthe radar signals from the sensor. Thesensor is in the lower grille. The systemcannot detect a vehicle ahead and doesnot function when something blocks thesensor.
Note:You cannot see the sensor. It isbehind a fascia panel.
Keep the front of your vehicle free of dirt,metal badges or objects. Vehicle frontprotectors and aftermarket lights may alsoblock the sensor.

Possible causes and actions for a message displaying:
ActionCause
Clean the grille surface in front of the radarof remove the object causing the obstruc-tion.
The surface of the radar is dirty orobstructed
Wait a short time. It may take severalminutes for the radar to detect that it is freefrom obstruction.
The surface of the radar is clean but themessage remains in the display.
Do not use the system in these conditionsbecause it may not detect any vehiclesahead.
Heavy rain or snow is interfering with theradar signals
Do not use the system in these conditionsbecause it may not detect any vehiclesahead.
Water, snow or ice on the surface of theroad may interfere with the radar signals.
Wait a short time or switch to normal cruisecontrol.You are in a desert or remote area with notother vehicles and no roadside objects.
Due to the nature of radar technology, it is possible to get a blockage warning with noactual block. A false blocked condition either self clears, or clears after you restart yourvehicle.
Switching to Normal CruiseControl
WARNING: Normal cruise controlwill not brake when your vehicle isapproaching slower vehicles. Always beaware of which mode you have selectedand apply the brakes when necessary.
The cruise control indicator lightreplaces the adaptive cruisecontrol indicator light if youselect normal cruise control. The gapsetting does not display, and the systemdoes not respond to lead vehicles.Automatic braking remains active tomaintain set speed. You can change fromadaptive cruise control to normal cruisecontrol through the information display.
You can change from adaptive cruisecontrol to normal cruise control throughthe information display.
