If these modified engine performancecharacteristics persist for an extendedperiod and either the service engine soonor powertrain malfunction, reduced power,electronic throttle control light isilluminated, have the system checked byan authorized dealer.
Service engine soon
Powertrain malfunction, reducedpower, electronic throttle control
Diesel Lubrication System
It is important to change the engine oil atthe recommended service intervals orwhen indicated by the information displayto maintain oil viscosity. Extending the oiland filter change interval beyond therecommended interval can negativelyaffect engine performance, fuel economyand engine life. See Engine Oil Check(page 227).
Engine and secondary cooling system
The cooling system contains a primarycooling loop to cool the engine and asecondary cooling loop to cool thetransmission, charge air, and fuel. Thecoolant serves three primary purposes: toprovide heat transfer, freeze pointprotection, and corrosion protection usingadditives.
Vehicles with diesel engines typically areused to carry heavy loads and accumulatemileage rapidly. These two factors maycause the additives in the coolant to wearout in a shorter time. You can find moreinformation about coolant additives andcoolant change intervals in the coolantchapter. See General MaintenanceInformation (page 325). Operating theengine with insufficient coolant or coolantadditive can cause severe engine damage.
Selective catalytic reduction system
Your vehicle is equipped with a selectivecatalytic reduction system designed toreduce emission levels of nitrogen oxidesfrom the exhaust of your diesel engine. Thissystem relies on the use of Diesel ExhaustFluid (DEF) that you must replenish atcertain intervals. Failure to maintain properDEF levels or if the DEF becomescontaminated will result in vehicle speedlimitations or result in your vehicle enteringan idle-only mode. See SelectiveCatalytic Reductant System (page 120).
Minor Troubleshooting Guide
If the engine won’t crank
WARNING: Battery posts,terminals and related accessoriescontain lead and lead compounds. Washhands after handling.
Turn on the headlights. If the lights are dim,do not go on at all or when the ignition isturned to the start position, the lightsbecome dim or go out, the batteryconnections may be loose or corroded, orthe battery may be discharged. If there isa clicking or stuttering sound coming fromthe engine compartment when you turnthe key to the start position, this may alsoindicate a loose or corroded batteryconnection.
Check the battery connections at thebattery posts, cable connection to theengine grounding point and at the starterconnection.
If you suspect a discharged battery, haveit checked and corrected.

Engine Oil Pressure Gauge
Indicates engine oil pressure. At normaloperating temperature, the level indicatoris in the normal range. If the pressure gaugefalls below the normal range, stop yourvehicle, switch off the engine and checkthe engine oil level. Add oil if needed. If theoil level is correct, have your vehiclechecked by an authorized dealer.
Engine Coolant TemperatureGauge
WARNING: Do not remove thecoolant reservoir cap when the engine ison or the cooling system is hot. Wait 10minutes for the cooling system to cooldown. Cover the coolant reservoir capwith a thick cloth to prevent thepossibility of scalding and slowly removethe cap. Failure to follow this instructioncould result in personal injury.
Indicates engine coolant temperature. Atnormal operating temperature, the levelindicator is in the normal range. If theengine coolant temperature exceeds thenormal range, stop your vehicle as soon aspossible, switch off the engine and let theengine cool.
Fuel Gauge
The fuel gauge indicates about how muchfuel is in the fuel tank.
The arrow adjacent to the fuel pumpsymbol indicates on which side of yourvehicle the fuel filler door is located.
Note:The fuel gauge may vary slightlywhen your vehicle is moving or on a slope.
Low Fuel Reminder
A low fuel level reminder displays andsounds when the distance to emptyreaches 50 mi (80 km),25 mi (40 km),10 mi (20 km) and 0 mi (0 km) for allvehicle keys.
Note:The low fuel reminder can appear atdifferent fuel gauge positions depending onfuel economy conditions. This variation isnormal.
Distance to Empty
Indicates the approximate distance yourvehicle can travel on the fuel remaining inthe tank. Changes in driving pattern cancause the value to not only decrease butalso increase or stay constant for periodsof time.
Configurable Gauge
Transmission Fluid Temperature Gauge
Indicates transmission fluid temperature.At normal operating temperature, the levelindicator is in the normal range. If thetransmission fluid temperature exceedsthe normal range, stop your vehicle as soonas possible and verify the airflow is notrestricted by snow or debris blockingairflow through the grille.
Special operating conditions such assnowplowing, towing, or off-road use maycause higher than normal operatingtemperatures. See Special OperatingConditions Scheduled Maintenance(page 335).
To lower the transmission temperatureinto the normal range, alter the severity ofyour driving conditions. Operating thetransmission for extended periods with thegauge in the higher than normal area maycause internal transmission damage. If thegauge continues to show hightemperatures, see an authorized dealer.

Your vehicle may not pass the I/M test ifthe service engine soon indicator is on ornot working properly (bulb is burned out),or if the OBD-II system has determinedthat some of the emission control systemshave not been properly checked. In thiscase, the vehicle is not ready for I/Mtesting.
If the vehicle’s engine or transmission hasjust been serviced, or the battery hasrecently run down or been replaced, theOBD-II system may indicate that thevehicle is not ready for I/M testing. Todetermine if the vehicle is ready for I/Mtesting, turn the ignition key to the onposition for 15 seconds without crankingthe engine. If the service engine soonindicator blinks eight times, it means thatthe vehicle is not ready for I/M testing; ifthe service engine soon indicator stays onsolid, it means that your vehicle is readyfor I/M testing.
The OBD-II system checks the emissioncontrol system during normal driving. Acomplete check may take several days.
If the vehicle is not ready for I/M testing,you can perform the following driving cycleconsisting of mixed city and highwaydriving:
1.15 minutes of steady driving on anexpressway or highway followed by 20minutes of stop-and-go driving with atleast four 30-second idle periods.
2.Allow your vehicle to sit for at leasteight hours with the ignition off. Then,start the vehicle and complete theabove driving cycle. The vehicle mustwarm up to its normal operatingtemperature. Once started, do not turnoff the vehicle until the above drivingcycle is complete.
If the vehicle is still not ready for I/Mtesting, you need to repeat the abovedriving cycle.
SELECTIVE CATALYTIC
REDUCTANT SYSTEM - DIESEL
Your vehicle may have a selective catalyticreduction system. This system helpsreduce emission levels of oxides ofnitrogen from the exhaust system. Thesystem automatically injects dieselexhaust fluid into the exhaust system toenable correct selective catalytic reductionsystem function.
Note:Selective catalytic reduction systemsare not fitted to vehicles in markets whereonly high-sulfur diesel fuel is available.
Diesel Exhaust Fluid Level
In order for the system to operate correctlyyou must maintain the diesel exhaust fluidlevel.
The system has a sensor to monitor fluidlevel and quality/concentration. A warningmessage appears in the informationdisplay when the diesel exhaust fluid levelis low. If a warning message appears, refillthe diesel exhaust fluid tank as soon aspossible. See Information Messages(page 75).
Filling the Diesel Exhaust FluidTank
WARNING: Keep diesel exhaustfluid out of reach of children. Avoidcontact with skin, eyes or clothing. Incase of contact with your eyes, flushimmediately with water and get promptmedical attention. In case of contactwith your skin, clean immediately withsoap and water. If you swallow anydiesel exhaust fluid, drink plenty ofwater, call a physician immediately.

At this time, you may notice the coolanttemperature gauge moves toward the redzone and a message may appear in theinformation display.
You may notice a reduction in vehiclespeed caused by reduced engine power inorder to manage the engine coolanttemperature. Your vehicle may enter thismode if certain high-temperature andhigh-load conditions take place. Theamount of speed reduction depends onvehicle loading, grade and ambienttemperature. If this occurs, there is noneed to pull off the road. You can continueto drive your vehicle.
The air conditioning may turn on and offduring severe operating conditions toprotect the engine from overheating. Whenthe coolant temperature decreases to thenormal operating temperature, the airconditioning turns on.
If the coolant temperature gauge movesfully into the red zone, or if the coolanttemperature warning or service enginesoon messages appear in your informationdisplay, do the following:
1.Pull off the road as soon as safelypossible and shift the transmission intopark (P).
2.Leave the engine running until thecoolant temperature gauge needlereturns to the normal position. Afterseveral minutes, if the temperaturedoes not drop, follow the remainingsteps.
3.Switch the engine off and wait for it tocool. Check the coolant level.
4.If the coolant level is at or below theminimum mark, add prediluted coolantimmediately.
5.If the coolant level is normal, restartthe engine and continue.
AUTOMATIC TRANSMISSION
FLUID CHECK
The transmission does not consume fluid.However, check the fluid level if thetransmission is not working properly, forexample if the transmission slips, shiftsslowly or if there are signs of fluid loss.
Replace the transmission fluid and filteron your vehicle at the specified serviceinterval. See Scheduled Maintenance(page 325).
Automatic transmission fluid expandswhen warmed. To check the fluid levelconsistently and accurately, do thefollowing:
1.Drive the vehicle until it reaches normaloperating temperature. This may takeup to 20 mi (30 km). Make sure thatthe transmission fluid temperaturegauge on the instrument cluster iswithin normal operating temperature196–215°F (91–102°C) beforechecking.
2.Make sure that your vehicle is on levelground.
3.With the engine running, parking brakeengaged and your foot on the brakepedal, move the gearshift lever throughall of the gear ranges. Allow sufficienttime for each gear to engage.
4.Make sure the parking brake is on. Makesure the transmission is in park (P) orneutral (N) and leave the enginerunning.
5.Open the hood. See Opening andClosing the Hood (page 223).
6.Remove the dipstick and wipe it witha clean, lint-free cloth. See UnderHood Overview (page 225).
7.Replace the dipstick and remove itagain to check the fluid level.

8.If the fluid level is correct, replace thedipstick and make sure it is fully seated.
Note:If the fluid level is between themaximum and minimum marks, the fluidlevel is acceptable. Do not add fluid.
Transmission Fluid Level
Low Fluid Level
If the fluid level is at or below the minimummark, add fluid immediately. SeeAutomatic Transmission FluidCapacity and Specification (page 307).
Note:If there is no indication of fluid on thedipstick, have your vehicle checkedimmediately.
Correct Fluid Level
Make sure that the fluid level is betweenthe maximum and minimum marks.
High Fluid Level
Do not add fluid further than the maximummark. Fluid levels above the maximummark could cause shift or engagementconcerns and possible damage.
Note:An overheating condition can causehigh fluid levels.
Adding Transmission Fluid
Do not use supplemental transmissionfluid additives, treatments or cleaningagents. The use of these materials couldaffect transmission operation and resultin damage to internal transmissioncomponents and could lead totransmission damage that the vehicleWarranty does not cover.
Use only recommended transmission fluidthat meets our specifications. SeeAutomatic Transmission FluidCapacity and Specification (page 307).
Note:Use of a non-approved automatictransmission fluid could cause internaltransmission component damage.
If necessary, add fluid in 8 fl oz (250 ml)increments through the filler tube until thelevel is correct.
If an overfill occurs, remove excess fluidand have your vehicle checked as soon aspossible.

•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
