Tow/Haul Mode
WARNING
Do not use the tow/haul featurewhen driving in icy or slipperyconditions as the increased enginebraking can cause the wheels to slide andyour vehicle to swing around with thepossible loss of vehicle control.
To activate tow/haul, press thebutton on the gearshift leveronce. The TOW HAUL indicatorlight will illuminate in the instrumentcluster.
To deactivate the tow/haul feature andreturn to normal driving mode, press thebutton on the gearshift lever again. TheTOW HAUL light will deactivate. Tow/haulwill also deactivate when your power downyour vehicle.
The tow/haul feature:
•Delays upshifts to reduce the frequencyof transmission shifting.
•Provides engine braking in all forwardgears, which will slow your vehicle andassist you in controlling your vehiclewhen descending a grade.
•Depending on driving conditions andload conditions, may downshift thetransmission, slow your vehicle andcontrol your vehicle speed whendescending a hill, without pressing theaccelerator pedal. The amount ofdownshift braking provided will varybased upon the amount the brakepedal is pressed.
The tow/haul feature improvestransmission operation when towing atrailer or a heavy load. All transmissiongear ranges are available when usingtow/haul.
Automatic Transmission AdaptiveLearning
This feature may increase durability andprovide consistent shift feel over the lifeof your vehicle. A new vehicle ortransmission may have firm shifts, softshifts or both. This operation is considerednormal and will not affect function ordurability of the transmission. Over time,the adaptive learning process will fullyupdate transmission operation.
Forced Downshifts
•Allowed in drive (D) with the tow/haulfeature on or off.
•Press the accelerator pedal 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.
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 moving thegearshift lever from park (P) when theignition is in the on position and the brakepedal is not pressed.
If you cannot move the gearshift lever outof park (P) position with the ignition in theon position and the brake pedal pressed,a malfunction may have occurred. It ispossible that a fuse has blown or yourvehicle’s brake lamps are not operatingproperly. See Fuse Specification Chart(page 63).
If the fuse is not blown and the brakelamps are working properly, the followingprocedure will allow you to move thegearshift lever from park (P):
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 the transmission toneutral (N).
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.
If Your Vehicle Gets Stuck In Mudor Snow
Note:Do not rock your vehicle if the engineis not at normal operating temperature ordamage to the transmission may occur.
Note:Do not rock your vehicle for morethan a minute or damage to thetransmission and tires may occur, or theengine may overheat.
If your vehicle gets stuck in mud or snow,you may rock it out by shifting betweenforward and reverse gears, stoppingbetween shifts in a steady pattern. Presslightly on the accelerator in each gear.

GENERAL INFORMATION
Note:Occasional brake noise is normal. Ifa metal-to-metal, continuous grinding orcontinuous squeal sound is present, thebrake linings may be worn-out and shouldbe inspected by an authorized dealer. If thevehicle has continuous vibration or shudderin the steering wheel while braking, thevehicle should be inspected by anauthorized dealer.
Note:Brake dust may accumulate on thewheels, even under normal drivingconditions. Some dust is inevitable as thebrakes wear and does not contribute tobrake noise. See Cleaning the AlloyWheels (page 95).
See the Instrument Clusterchapter for information on thebrake system warning light.
Wet brakes result in reduced brakingefficiency. Gently press the brake pedal afew times when driving from a car wash orstanding water to dry the brakes.
Brake Over Accelerator
In the event the accelerator pedalbecomes stuck or entrapped, apply steadyand firm pressure to the brake pedal toslow the vehicle and reduce engine power.If you experience this condition, apply thebrakes and bring your vehicle to a safestop. Turn the engine off, shift thetransmission into park (P), apply theparking brake, and then inspect theaccelerator pedal for any interferences. Ifnone are found and the condition persists,have your vehicle towed to the nearestauthorized dealer.
Hydraulic brake booster system(Hydroboost or Hydromax)
The Hydroboost and Hydromax systemsreceive fluid pressure from the powersteering pump to provide power assistduring braking.
The Hydromax booster receives backuppressure from the reserve system electricpump whenever the fluid in the powersteering system is not flowing. When theengine is off, the pump will turn on if thebrake pedal is applied, or if the ignition isturned to the on position.
The sound of the pump operating may beheard by the driver, but this is a normalcharacteristic of the system.
The reserve system provides reducedbraking power, so the vehicle should beoperated under these conditions withcaution, and only to seek service repair andremove the vehicle from the roadway.
Note:For Hydromax-equipped vehiclesoperating under normal conditions, the noiseof the fluid flowing through the booster maybe heard whenever the brake is applied. Thiscondition is normal. Vehicle service is notrequired.
If braking performance or pedal responsebecomes very poor, even when the pedalis strongly pressed, it may indicate thepresence of air in the hydraulic system orleakage of fluid. Stop the vehicle safely assoon as possible and seek serviceimmediately.
HINTS ON DRIVING WITH
ANTI-LOCK BRAKES
Note:When the system is operating, thebrake pedal will pulse and may travelfurther. Maintain pressure on the brakepedal. You may also hear a noise from thesystem. This is normal.

TOWING A TRAILER
WARNINGS
Do not exceed the GVWR orthe GAWR specified on thecertification label.
Towing trailers beyond themaximum recommendedgross trailer weight exceeds thelimit of the vehicle and couldresult in engine damage,transmission damage, structuraldamage, loss of vehicle control,vehicle rollover and personalinjury.
Your vehicle may have electricalitems, such as fuses or relays,related to towing. See the Fuseschapter.
Your vehicle's load capacitydesignation is by weight, not byvolume, so you cannot necessarilyuse all available space whenloading a vehicle or trailer.
Towing a trailer places an extraload on your vehicle's engine,transmission, axle, brakes, tiresand suspension. Inspect thesecomponents periodically during,and after, any towing operation.
Load Placement
To help minimize how trailermovement affects your vehiclewhen driving:
•Load the heaviest items closestto the trailer floor.
•Load the heaviest itemscentered between the left andright side trailer tires.
•Load the heaviest items abovethe trailer axles or just slightlyforward toward the trailertongue. Do not allow the finaltrailer tongue weight to goabove or below 10-15% of theloaded trailer weight.
•Select a tow bar with thecorrect rise or drop. When boththe loaded vehicle and trailerare connected, the trailer frameshould be level, or slightlyangled down toward yourvehicle, when viewed from theside.
When driving with a trailer orpayload, a slight takeoff vibrationor shudder may be present due tothe increased payload weight.Additional information regardingproper trailer loading and settingyour vehicle up for towing islocated in another chapter of thismanual. See Load Limit (page38).
You can also find information inthe RV & Trailer Towing Guideavailable at your authorizeddealer, or online.

Trailer Brakes
WARNING
Do not connect a trailer's hydraulicbrake system directly to yourvehicle's brake system. Your vehiclemay not have enough braking power andyour chances of having a collision greatlyincrease.
Electric brakes and manual, automatic orsurge-type trailer brakes are safe if youinstall them properly and adjust them tothe manufacturer's specifications. Thetrailer brakes must meet local and federalregulations.
The rating for the tow vehicle's brakingsystem operation is at the gross vehicleweight rating, not the gross combinedweight rating.
Separate functioning brake systemsare required for safe control of towedvehicles and trailers weighing morethan 1500 pounds (680 kilograms)when loaded.
Trailer Lamps
WARNING
Never connect any trailer lamp wiringto the vehicle's tail lamp wiring; thismay damage the electrical systemresulting in fire. Contact your authorizeddealer as soon as possible for assistancein proper trailer tow wiring installation.Additional electrical equipment may berequired.
Trailer lamps are required on most towedvehicles. Make sure all running lights, brakelights, direction indicators and hazard lightsare working.
Before Towing a Trailer
Practice turning, stopping and backing upto get the feel of your vehicle-trailercombination before starting on a trip.When turning, make wider turns so thetrailer wheels clear curbs and otherobstacles.
When Towing a Trailer
•Do not drive faster than 70 mph(113 km/h) during the first 500 mi(800 km).
•Do not make full-throttle starts.
•Check your hitch, electrical connectionsand trailer wheel lug nuts thoroughlyafter you have traveled 50 mi (80 km).
•When stopped in congested or heavytraffic during hot weather, place thegearshift in park (P) to aid engine andtransmission cooling and to help airconditioning performance.
•Switch off the speed control withheavy loads or in hilly terrain. Thespeed control may turn offautomatically when you are towing onlong, steep grades.
•Shift to a lower gear when driving downa long or steep hill. Do not apply thebrakes continuously, as they mayoverheat and become less effective.
•If your transmission is equipped with aGrade Assist or Tow/Haul feature, usethis feature when towing. This providesengine braking and helps eliminateexcessive transmission shifting foroptimum fuel economy andtransmission cooling.
•Allow more distance for stopping witha trailer attached. Anticipate stops andbrake gradually.
•Avoid parking on a grade. However, ifyou must park on a grade:
1.Turn the steering wheel to point yourvehicle tires away from traffic flow.

BREAKING-IN
You need to break in new tires forapproximately 300 miles (480kilometers). During this time, your vehiclemay exhibit some unusual drivingcharacteristics.
Avoid driving too fast during the first 1000miles (1600 kilometers). Vary your speedfrequently and change up through thegears early. Do not labor the engine.
Do not tow during the first 1000 miles(1600 kilometers).
REDUCED ENGINE
PERFORMANCE
WARNING
Continued operation will increase theengine temperature and cause theengine to shut down completely.
If the engine coolant temperature gaugeneedle moves to the upper limit position,the engine is overheating. See Gauges(page 13).
You must only drive your vehicle for a shortdistance if the engine overheats. Thedistance you can travel depends onambient temperature, vehicle load andterrain. The engine will continue to operatewith limited power for a short time.
If the engine temperature continues to rise,the fuel supply to the engine will reduce.The air conditioning will switch off and theengine cooling fan will operate continually.
1.Reduce your speed gradually and stopyour vehicle as soon as it is safe to doso.
2.Switch the engine off immediately toprevent severe engine damage.
3.Wait for the engine to cool down.
4.Check the coolant level. See EngineCoolant Check (page 84).
5.Have your vehicle checked by anauthorized dealer as soon as possible.
ECONOMICAL DRIVING
Your fuel economy is affected by severalthings, such as how you drive, theconditions you drive under, and how youmaintain your vehicle.
You may improve your fuel economy bykeeping these things in mind:
•Accelerate and slow down in a smooth,moderate fashion.
•Drive at steady speeds withoutstopping.
•Anticipate stops; slowing down mayeliminate the need to stop.
•Combine errands and minimizestop-and-go driving.
•Close the windows for high-speeddriving.
•Drive at reasonable speeds (travelingat 55 mph [88 km/h] uses 15% lessfuel than traveling at 65 mph [105km/h]).
•Keep the tires properly inflated and useonly the recommended size.
•Use the recommended engine oil.
•Perform all regularly scheduledmaintenance.
Avoid these actions; they reduce your fueleconomy:
•Sudden accelerations or hardaccelerations.
•Revving the engine before turning it off.
•Idle for periods longer than one minute.
•Warm up your vehicle on coldmornings.
•Use the air conditioner or frontdefroster.
51Motorhome (TY3) , enUSA, First PrintingDriving Hints

•Use the speed control in hilly terrain.
•Rest your foot on the brake pedal whiledriving.
•Drive a heavily loaded vehicle or tow atrailer.
•Carry unnecessary weight(approximately 1 mpg [0.4 km/L] islost for every 400 lb [180 kilogram] ofweight carried).
•Driving with the wheels out ofalignment.
Conditions
•Heavily loading a vehicle or towing atrailer may reduce fuel economy at anyspeed.
•Adding certain accessories to yourvehicle (for example bug deflectors,rollbars, light bars, running boards, skiracks or luggage racks) may reducefuel economy.
•To maximize the fuel economy, drivewith the tonneau cover installed (ifequipped).
•Using fuel blended with alcohol maylower fuel economy.
•Fuel economy may decrease with lowertemperatures during the first 8–10miles (12–16 kilometers) of driving.
•Driving on flat terrain offers improvedfuel economy as compared to drivingon hilly terrain.
•Transmissions give their best fueleconomy when operated in the topcruise gear and with steady pressureon the gas pedal.
•Four-wheel-drive operation (ifequipped) is less fuel efficient thantwo-wheel-drive operation.
•Close the windows for high-speeddriving.
DRIVING THROUGH WATER
WARNING
Do not drive through flowing or deepwater as you may lose control of yourvehicle.
Note:Driving through standing water cancause vehicle damage.
Note:Engine damage can occur if waterenters the air filter.
Before driving through standing water,check the depth. Never drive through waterthat is higher than the bottom of the wheelhubs.
When driving through standing water, drivevery slowly and do not stop your vehicle.Your brake performance and traction maybe limited. After driving through water andas soon as it is safe to do so:
•Lightly press the brake pedal to dry thebrakes and to check that they work.
•Check that the horn works.
•Check that the exterior lights work.
