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.

•Your load shifts due to improperretention, accident damage or theinherently mobile nature of some loads,for example, hanging meat, liveanimals or partially laden tankers.
•Your vehicle or load has an unusuallyhigh or off-set center of gravity.
•Your brakes are not properly adjustedor maintained.
•One side of your vehicle drops off thepavement at an angle that is too greatto be counteracted by a reduction inspeed.
To Maximize the Effectiveness OfStability Control
•Make sure that the weight of your loadis evenly distributed, from front to back,side to side and you secure it properlyat all times.
•Exercise extreme caution at all timeswhile driving and avoid sharp turns,sudden steering inputs or abrupt lanechanges at high speeds, particularly if:
•Hauling loads that can shift.
•Your vehicle or load has a high oroff-set center of gravity whenloaded.
•You are towing doubles or triples.
Electronic Stability Control Usage withTractor/Trailer
The electronic stability control system isdesigned to work with trailer air brakesystems. We do not recommend its usewith any other trailer brake system.
Electronic Stability Control and Towingwith Non-tractor Trucks (Straight orKick-up Frame)
Non-tractor trucks (straight or kick-upframe) with air brake electronic stabilitycontrol, should not be used for towing anytype of trailer.

STEERING
Hydraulic Power Steering
To help prevent damage to the powersteering system:
•Do not hold the steering wheel at itsfurthest turning points for more thanthree to five seconds when the engineis running.
•Avoid continuously steering back andforth with elevated engine RPM as thismay overheat the system. If trying tofree a stuck vehicle, pause betweenattempts to allow the power steeringsystem to cool or seek assistance.Typical steering and driving maneuversallow the system to cool.
•Do not operate the vehicle if the powersteering pump fluid level is below theMIN mark on the reservoir.
•Some noise is normal during operation.If excessive, check for low powersteering pump fluid level beforeseeking service by your dealer.
•Heavy or uneven efforts may be causedby low power steering fluid. Check forlow power steering pump fluid levelbefore seeking service by your dealer.
•Do not fill the power steering pumpreservoir above the MAX mark on thereservoir, as this may result in leaksfrom the reservoir.
If the power steering system breaks downor if you switch the engine off, you cansteer the vehicle manually, but it takesmore effort.
If you have any steering componentsserviced or replaced, install new fasteners.Many fasteners have coatings with threadadhesive, or have prevailing torquefeatures you cannot reuse. Do not reuse abolt or nut. Torque fasteners tospecifications.
Steering Tips
If the steering wanders or pulls, check for:
•An improperly inflated tire.
•Uneven tire wear.
•Loose or worn suspensioncomponents.
•Loose or worn steering components.
•Improper vehicle alignment.
Note:A high crown in the road or highcrosswinds may also make the steeringseem to wander or pull.

AIR SUSPENSION
Note:Do not operate your vehicle withoutair in the suspension springs. Operating yourvehicle without air in the suspension springsdamages the suspension, degrades rideperformance and may cause propertydamage.
The air suspension system automaticallyadjusts to different loads to maintain aconstant frame height, allows for ease ofvehicle loading, provides improved vehicleride, and increased driver comfort.
Air Suspension Dump Button
Note:The suspension dumps air when theignition is in the accessory or on position,but fills only when the ignition is in the onposition.
A button located on the instrument panelcontrols the system. It operates only whenthe ignition is in the accessory or onposition and the air tanks have sufficientpressure to fill the air springs. When youturn off the ignition, the suspensionremains in whatever state it was last set.
Pressing and holding the button for twoseconds exhausts air from the air springs,lowering the frame for loading. Pressingand holding the button for two secondsfills the air springs so your vehicle remainsat normal ride height.
System Indicator Light
The air suspension indicator lightilluminates when using the button torelease air pressure in the rear air springs.Never drive your vehicle when the warninglamp is illuminated and there is low (or no)air pressure in the springs.
Connecting and Disconnecting aTrailer with Air Suspension and AirSuspension Dump Button
When connecting to a trailer:
•Press and hold the button for twoseconds to exhaust air from the airsuspension system.
•Press and hold the button for twoseconds, and then raise the landinggear after making the connection tothe trailer.
When disconnecting the trailer:
