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.
