POWER STEERING FLUID
CHECK
Check the power steering fluid. SeeScheduled Maintenance (page 325). Ifadding fluid is necessary, use onlyMERCON LV ATF
Check the fluid level when it is at ambienttemperature.
1.Check the fluid level in the reservoir. Itshould be between the MIN and MAXrange. Do not add fluid if the level iswithin this range.
2.If the fluid level is low, add fluid to bringthe fluid level up to between the MINand MAX range.
3.Switch the engine on.
4.While the engine idles, turn the steeringwheel left and right several times.
5.Switch the engine off.
6.Recheck the fluid level in the reservoir.Do not add fluid if the level is betweenthe MIN and MAX range.
7.If the fluid is low, add the proper typeof fluid in small amounts, continuouslychecking the level until it is betweenthe MIN and MAX range. SeeHydraulic Power Steering FluidCapacity and Specification (page312). Be sure to put the cap back on thereservoir.
CHANGING THE 12V BATTERY
WARNING: This vehicle may beequipped with more than one battery,removal of cable from only one batterydoes not disconnect the vehicleelectrical system. Be sure to disconnectcables from all batteries whendisconnecting power. Failure to do somay cause serious personal injury orproperty damage.
WARNING: Batteries normallyproduce explosive gases which cancause personal injury. Therefore, do notallow flames, sparks or lightedsubstances to come near the battery.When working near the battery, alwaysshield your face and protect your eyes.Always provide proper ventilation.
WARNING: When lifting aplastic-cased battery, excessive pressureon the end walls could cause acid to flowthrough the vent caps, resulting inpersonal injury and damage to thevehicle or battery. Lift the battery with abattery carrier or with your hands onopposite corners.
WARNING: Keep batteries out ofreach of children. Batteries containsulfuric acid. Avoid contact with skin,eyes or clothing. Shield your eyes whenworking near the battery to protectagainst possible splashing of acidsolution. In case of acid contact with skinor eyes, flush immediately with water fora minimum of 15 minutes and get promptmedical attention. If acid is swallowed,call a physician immediately.
Note:If your battery has a cover/shield,make sure it is reinstalled after the batteryhas been cleaned or replaced.

•Maintaining proper steering gear andpower steering pump lubricant levels.
•Checking steering column joint boltsand steering linkage, particularly forbody-to-chassis clearance.
Steering Column Joint Bolts
As a good maintenance practice, checksteering column joint bolt tightness every60,000 mi (96,000 km) or annually,whichever occurs first. Do not overtightenthe bolts.
Hydraulic System
Whenever draining and refilling the powersteering's hydraulic system for any reason,bleed air from the system before returningthe vehicle to service. Failure to bleed thehydraulic system properly can result indegradation of power system performance.
Consult an authorized dealer who is awareof the proper procedures for filling andbleeding the system.
SUSPENSION SYSTEM
INSPECTION (IF EQUIPPED)
Note:Do not adjust air suspension heightto any setting other than the specifiedsetting. Altering the height setting changesthe driveline angle and may result inunwarrantable component damage, suchas transmission component damage.
Verify drive axle air suspension height andheight control valve performance at engineoil change intervals.
Periodically check:
•Condition of spring leaves for evidenceof fatigue, bending or breakage.
•Condition of suspension mountingbrackets and bushings.
•Torque rod mounting fasteners fortightness.
•For proper suspension alignment.Maintain proper alignment at all times.
•U-bolts. After the chassis has beenoperating under load for 1,000 mi(1,600 km) or six months (whichevercomes first), the U-bolt nuts must bere-torqued. Re-torque the U-bolt nutsevery 37,000 mi (60,000 km)thereafter. Clean and lubricate theU-bolt and nut threads and seats tomake sure a like new condition whenre-torqueing. See Spring U-BoltCheck (page 261).
FRAME AND TOW HOOK
INSPECTION
Your vehicle's chassis is manufacturedwith frame rails of either HSLA steel orheat-treated steel. Handle each in aspecific manner to make sure maximumservice life. Consult the service manual oran authorized dealer before attemptingframe repair or modification.
It is important, particularly on vehicles thatuse tow hooks frequently, to inspect thefront and rear tow hooks for damage or aloose mounting.
REAR AXLE FLUID CHECK
Your rear axle may have an optionalsynthetic lubricant that allows the use ofextended service intervals. A tag on thefiller plug identifies the use of the syntheticlubricant.
Only use a lubricant that meetsmanufacturer specifications. Use of anon-approved rear axle lubricant maycause internal axle component damage.See Rear Axle Fluid Capacity andSpecification (page 311).
Checking the Fluid Level
1.Park your vehicle on level ground.

MAINTENANCE
Intelligent Oil-Life Monitor™
Your vehicle has an Intelligent Oil-LifeMonitor that determines when you shouldchange the engine oil based on how youuse your vehicle. By using severalimportant factors in its calculations, themonitor helps reduce the cost of owningyour vehicle and reduces environmentalwaste at the same time.
This means you do not have to rememberto change the oil on a mileage-basedschedule. Your vehicle lets you know whenan oil change is due by displaying amessage in the instrument cluster display.
The following table provides examples ofvehicle use and its impact on oil changeintervals. It is a guideline only. Actual oilchange intervals depend on several factorsand generally decrease with severity ofuse.
