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.
PNEUMATIC LOCKING
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.
SWITCHING THE PNEUMATIC
LOCKING DIFFERENTIAL ON
AND OFF
Press and hold the button on the dash toturn the system on or off.

PRINCIPLE OF OPERATION
The traction control system helps avoiddrive wheel spin and loss of traction.
If your vehicle begins to slide, the systemapplies the brakes to individual wheelsand, when needed, reduces engine powerat the same time. If the wheels spin whenaccelerating on slippery or loose surfaces,the system reduces engine power in orderto increase traction.
USING TRACTION CONTROL -
VEHICLES WITH: AIR BRAKES
WARNING: Operating your vehiclewith the traction control disabled couldlead to an increased risk of loss of vehiclecontrol, vehicle rollover, personal injuryand death.
Press the TCS Off button on theinstrument panel to enable themud/snow mode.
This is beneficial when your vehicle is stuckin snow or on a slippery road surface. Thismode allows wheel spin to dig your vehicleout and allows you to rock your vehicle.
Press the switch again to select standardtraction control. The system automaticallyselects standard traction control at thenext ignition cycle.
System Indicator Light
Note:If the traction control light does notflash during a traction control event or staysilluminated, the system is not functioningproperly. Take your vehicle to an authorizeddealer for service.
During traction control operation, thetraction control light flashes rapidly andthe engine does not rev-up when you pressfurther on the accelerator. This is normaland is no reason for concern.
In mud/snow mode, the TCS OFF lightilluminates on the instrument cluster. If atraction event occurs in either mode, thestability and traction control light flashesrapidly.
USING TRACTION CONTROL -
VEHICLES WITH: HYDRAULIC
BRAKES
WARNING: Operating your vehiclewith the traction control disabled couldlead to an increased risk of loss of vehiclecontrol, vehicle rollover, personal injuryand death.
The system turns on each time you switchthe ignition on.
Use the traction control buttonon the instrument panel toswitch the system off or on.
If your vehicle is stuck in mud or snow,switching traction control off is beneficialas this allows the wheels to spin.
Press the button again to switch thetraction control system on.
System Indicator Light
Note:If the traction control light does notflash during a traction control event or stayson, the system is not operating. Have thesystem checked as soon as possible.
During a traction control event, the tractioncontrol light rapidly flashes. Pressingfurther on the accelerator does not causethe engine to rev higher. This is normal andis no reason for concern.

VEHICLES WITH: HYDRAULIC
BRAKES
WARNING: Vehicle modificationsinvolving braking system, aftermarketroof racks, suspension, steering system,tire construction and wheel and tire sizemay change the handling characteristicsof your vehicle and may adversely affectthe performance of the electronicstability control system. In addition,installing any stereo loudspeakers mayinterfere with and adversely affect theelectronic stability control system. Installany aftermarket stereo loudspeaker asfar as possible from the front centerconsole, the tunnel, and the front seatsin order to minimize the risk of interferingwith the electronic stability controlsensors. Reducing the effectiveness ofthe electronic stability control systemcould lead to an increased risk of loss ofvehicle control, vehicle rollover, personalinjury and death.
WARNING: Remember that evenadvanced technology cannot defy thelaws of physics. It's always possible tolose control of a vehicle due toinappropriate driver input for theconditions. Aggressive driving on anyroad condition can cause you to losecontrol of your vehicle increasing the riskof personal injury or property damage.Activation of the electronic stabilitycontrol system is an indication that atleast some of the tires have exceededtheir ability to grip the road; this could
reduce the operator's ability to controlthe vehicle potentially resulting in a lossof vehicle control, vehicle rollover,personal injury and death. If yourelectronic stability control systemactivates, SLOW DOWN.
The system turns on each time you switchthe ignition on.
If a fault occurs in either the stabilitycontrol or the traction control system, thefollowing conditions are possible:
•The stability and traction control lightilluminate.
•The stability control and tractioncontrol systems are not maintainingtraction of the wheels.
If a driving condition activates either thestability control or the traction controlsystem, the following conditions arepossible:
•The stability and traction control lightflash.
•Your vehicle slows down.
•The system reduces engine power.
•A vibration in the brake pedal.
•The brake pedal is stiffer than usual.
•If the driving condition is severe andyour foot is not on the brake, the brakepedal could move as the systemapplies higher brake force.
The stability control system has severalfeatures built into it to help you maintaincontrol of your vehicle:
Electronic Stability Control
The system assists in preventing skids orlateral slides by applying the brakes to oneor more of the wheels individually and, ifnecessary, decreases engine power.
