On-Board Diagnostics (OBD-II)
Your vehicle is equipped with an on-boarddiagnostics system (OBD-II) that monitorsthe engine’s emission control system. Thissystem protects the environment byensuring that your vehicle continues tomeet government emission standards. TheOBD-II system also assists your authorizeddealer in properly servicing your vehicle.
When the service engine soonindicator illuminates, the OBD-IIsystem has detected amalfunction. Temporary malfunctions maycause the service engine soon indicator toilluminate.
Examples of temporary malfunctions are:
•the vehicle has run out of fuel—theengine may misfire or run poorly
•poor fuel quality or water in thefuel—the engine may misfire or runpoorly
•the fuel fill inlet may not have beenproperly closed See Refueling (page24).
•driving through deep water—theelectrical system may be wet.
You can correct these temporarymalfunctions by filling the fuel tank withgood quality fuel, properly closing the fuelfill inlet or letting the electrical system dryout. After three driving cycles without theseor any other temporary malfunctionspresent, the service engine soon indicatorshould stay off the next time you start theengine. A driving cycle consists of a coldengine startup followed by mixedcity/highway driving. No additional vehicleservice is required.
If the service engine soon indicator remainson, have your vehicle serviced at the firstavailable opportunity. Although somemalfunctions detected by the OBD-II maynot have symptoms that are apparent,continued driving with the service enginesoon indicator on can result in increasedemissions, lower fuel economy, reducedengine and transmission smoothness, andlead to more costly repairs.
Readiness forInspection/Maintenance (I/M)Testing
Some state/provincial and localgovernments may haveInspection/Maintenance (I/M) programsto inspect the emission control equipmenton your vehicle. Failure to pass thisinspection could prevent you from gettinga vehicle registration.
27Motorhome (TY3) , enUSAFuel and Refueling

If the service engine soonindicator is on or the bulb doesnot work, you may need to havethe vehicle serviced. See On-BoardDiagnostics (OBD-II).
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, your 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 the vehicle is ready forI/M testing.
The OBD-II system monitors the emissioncontrol system during normal driving. Acomplete check may take several days. Ifthe vehicle is not ready for I/M testing, youmay need to perform the following drivingcycle consisting of mixed city and highwaydriving:
Drive on an expressway or highway for asteady 15 minutes, followed by 20 minutesof stop-and-go driving with at least four30-second idle periods.
Allow the vehicle to sit for at least eighthours without starting the engine. Then,start the engine and complete the abovedriving cycle. The engine must warm up toits normal operating temperature. Oncestarted, do not turn off the engine until theabove driving cycle is complete. If thevehicle is still not ready for I/M testing, youwill have to repeat the above driving cycle.

AUTOMATIC TRANSMISSION
WARNINGS
Always set the parking brake fullyand make sure the gearshift islatched in P (Park). Turn the ignitionto the off position and remove the keywhenever you leave your vehicle.
Do not apply the brake pedal andaccelerator pedal simultaneously.Applying both pedals simultaneouslyfor more than three seconds will limitengine rpm, which may result in difficultymaintaining speed in traffic and could leadto serious injury.
Understanding the Positions ofYour Automatic Transmission
This vehicle is equipped with an adaptivetransmission shift strategy. Adaptivetransmission shift strategy offers theoptimal transmission operation and shiftquality. When the vehicle’s battery hasbeen disconnected for any type of serviceor repair, the transmission will need torelearn the normal shift strategyparameters, much like having to reset yourradio stations when your vehicle batteryhas been disconnected. The adaptivetransmission shift strategy allows thetransmission to relearn these operatingparameters.
This learning process could take severaltransmission upshifts and downshifts;during this learning process, slightly firmershifts may occur. After this learningprocess, normal shift feel and shiftscheduling will resume.
Putting your vehicle in or out of gear:
1.Fully press down the brake pedal.
2.Move the gearshift lever into thedesired gear.
3.Come to a complete stop.
4.Move the gearshift lever and securelylatch it in P (Park)
P (Park)
This position locks the transmission andprevents the rear wheels from turning.Come to a complete stop before puttingyour vehicle into and out of P (Park)
R (Reverse)
With the gearshift lever in R (Reverse), thevehicle will move backward. Always cometo a complete stop before shifting into andout of R (Reverse).
N (Neutral)
With the gearshift lever in N (Neutral), thevehicle can be started and is free to roll.Hold the brake pedal down while in thisposition.
D (Overdrive) with tow/haul off
D (Overdrive) with tow/haul off is thenormal driving position for the best fueleconomy. The overdrive function allowsautomatic upshifts and downshifts throughgears one through five.

D (Overdrive) with tow/haul on
The tow/haul feature improvestransmission operation when towing atrailer or a heavy load. All transmissiongear ranges are available when usingtow/haul.
To activate tow/haul, press thebutton on the end of thegearshift lever. The TOW HAULindicator light will illuminate in theinstrument cluster.
Tow/haul delays upshifts to reducefrequency of transmission shifting.Tow/haul also provides engine braking inall forward gears when the transmission isin the D (Overdrive) position; this enginebraking will slow the vehicle and assist thedriver in controlling the vehicle whendescending a grade. Depending on drivingconditions and load conditions, thetransmission may downshift, slow thevehicle and control the vehicle speed whendescending a hill, without the acceleratorpedal being pressed. The amount ofdownshift braking provided will vary basedupon the amount the brake pedal ispressed.
Grade braking downshifts occurautomatically when all three of thefollowing occur:
•Positive vehicle acceleration (naturalacceleration from driving on a decline)is sensed.
•Nearly all pressure is released from theaccelerator pedal.
•A minimum amount of time has expiredsince the last grade braking downshift.
Grade braking downshift mode isimmediately exited if the Tow/Haul modeis deactivated or if the accelerator pedalis depressed beyond a minimum threshold.
To deactivate the tow/haul feature andreturn to normal driving mode, press thebutton on the end of the gearshift lever.The TOW HAUL light will no longer beilluminated.
When you shut-off and restart the engine,the transmission will automatically returnto normal D (Overdrive) mode (tow/hauloff).
WARNING
Do not use the tow/haul featurewhen driving in icy or slipperyconditions as the increased enginebraking can cause the rear wheels to slideand the vehicle to swing around with thepossible loss of vehicle control.
3 (Third)
Transmission starts and operates in thirdgear only
Used for improved traction on slipperyroads. Selecting 3 (Third) provides enginebraking.
2 (Second)
Use 2 (Second) to start-up on slipperyroads or to provide additional enginebraking on downgrades.
30Motorhome (TY3) , enUSATransmissionE161510 E161509

1 (First)
•Provides maximum engine braking
•Allows upshifts by moving gearshiftlever
•The transmission will not downshiftinto 1 (First) at high speeds; it willdownshift to a lower gear and thenshift into 1 (First) when the vehiclereaches slower speeds.
Forced downshifts
•Allowed in D (Overdrive) with thetow/haul feature on or off
•Press the accelerator to the floor
•Allows transmission to select anappropriate gear
Brake-Shift Interlock
WARNINGS
Do not drive your vehicle until youverify that the brake lamps areworking.
If your brake lamps are not workingproperly or if you have disconnectedthe vehicle battery cables, thevehicle brake lamps and hazard flashersmay not properly warn traffic of a vehiclebreakdown or approaching danger, whichcan increase the risk of serious injury ordeath. To minimize the risk of serious injuryor death, be aware of your surroundings,use other hazard signaling devices ifavailable, and move the vehicle to a safelocation away from traffic as soon aspossible.
When doing this procedure, you willbe taking the vehicle out of parkwhich means the vehicle can rollfreely. To avoid unwanted vehiclemovement, always fully set the parkingbrake prior to doing this procedure. Usewheel chocks if appropriate.
WARNINGS
If the parking brake is fully released,but the brake warning lamp remainsilluminated, the brakes may not beworking properly. See your authorizeddealer.
Your vehicle is equipped with a brake-shiftinterlock feature that prevents thegearshift lever from being moved from P(Park) unless the brake pedal is pressed.
If you cannot move the gearshift lever outof P (Park) position with the ignition in the4 (on) position and the brake pedalpressed, a malfunction may have occurred.It is possible that a fuse has blown or thevehicle’s brake lamps are not operatingproperly. Refer to Fuses and relays in theRoadside Emergencies chapter. If the fusesand brake lamps are working properly, andthe vehicle still will not shift out of (P)Park, see your authorized dealer for service.
In an emergency, to disable themalfunctioning brake-shift interlockfeature in order to shift the vehicle from P(Park) follow these steps:
1.Apply the parking brake. Turn key tothe lock position, and then remove thekey.
2.Disconnect the negative (black)battery cable from the battery.
3.Insert the key and turn to the offposition. Shift to N (Neutral).
4.Reconnect the negative (black) batterycable to the battery.
5.Start the vehicle.
Note:See your authorized dealer as soonas possible if this procedure is used.
