On-Board Diagnostics (OBD-II)
Your vehicle has a computer known as theon-board diagnostics system (OBD-II) thatmonitors the engine’s emission controlsystem. The system protects theenvironment by making sure that yourvehicle continues to meet governmentemission standards. The OBD-II systemalso assists a service technician in properlyservicing your vehicle.
When the service engine soonindicator illuminates, the OBD-IIsystem has detected amalfunction. Temporary malfunctions maycause the service engine soon indicator toilluminate. Examples are:
1.Your vehicle has run out of fuel—theengine may misfire or run poorly.
2.Poor fuel quality or water in thefuel—the engine may misfire or runpoorly.
3.The fuel fill inlet may not have closedproperly. See Refueling (page 176).
4.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 mixed city andhighway 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 for Inspection andMaintenance (I/M) Testing
Some state and 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.
If the service engine soonindicator is on or the bulb doesnot work, your vehicle may needservice. See On-Board Diagnostics.
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.

PRINCIPLE OF OPERATION
This system is a proactive system. It hasthe ability to anticipate wheel slip andtransfer torque to the rear wheels beforeslip occurs. Even when wheel slip is notpresent, the system is continuouslyadjusting to the torque distribution, in anattempt to improve straight line andcornering behavior, both on and off road.
The system automatically turns on everytime you switch the ignition on.
If any component requires maintenance,a message appears in the instrumentcluster display.
USING FOUR-WHEEL DRIVE
An image appears in the instrument clusterto advise you of the power distributionbetween the front and rear wheels. Themore the area is filled, the more power isbeing distributed to that wheel.
Note:Four-wheel drive is also called 4WDand 4x4.
Note:Do not use the four-wheel drive lock,the rear differential lock or off-roadselectable drive modes on dry, hardsurfaced roads. Doing so can produceexcessive noise, increase tire wear and maydamage drive components. These featuresare only intended for consistently slipperyor loose surfaces. Operating your vehicleoutside of these conditions could subjectthe vehicle to excessive stress, which mayresult in damage not covered under yourwarranty. See G.O.A.T. Mode Control(page 241).
Note:When a system malfunction ispresent, a warning message appears in theinstrument cluster. See InformationMessages (page 109). This means thesystem is not properly functioning and hasdefaulted to front-wheel drive. Have yourvehicle checked as soon as possible.
Note:A message appears in the instrumentcluster if the system overheats and switchesto front-wheel drive. This condition couldoccur if you operate your vehicle in extremehigh load conditions or with excessive wheelslip, for example deep sand. To resumefour-wheel drive function as soon aspossible, stop your vehicle in a safe locationand switch the ignition off for a minimumof 10 minutes. After the system cools,normal four-wheel drive functionalityresumes.
Note:If a warning message appears in theinstrument cluster when using the spare tire,it turns off after reinstalling the repaired orreplaced road tire and you perform a keycycle.
Note:It is recommended that you reinstallthe repaired tire or replace the tire as soonas possible. Major dissimilar tire sizes couldcause system damage or default the systemto front-wheel drive.

GENERAL INFORMATION
Note: Occasional brake noise is normal. Ifa metal-to-metal, continuous grinding orcontinuous squeal sound is present, thebrake linings could be worn-out and haveyour vehicle checked. If the vehicle hascontinuous vibration or shudder in thesteering wheel while braking, have yourvehicle checked.
Note: Brake dust may accumulate on thewheels, even under normal drivingconditions. Some dust is inevitable as thebrakes wear and does not contribute tobrake noise. Wet brakes result in reducedbraking efficiency. Gently press the brakepedal a few times when driving from a carwash or standing water to dry the brakes.
See Cleaning the Wheels (page 308).
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. Switch the engine off, move thetransmission to park (P) and apply theparking brake. Inspect the acceleratorpedal and the area around it for any itemsor debris that may be obstructing itsmovement. If none are found and thecondition persists, have your vehicle towedto have your vehicle checked.
Emergency Brake Assist
Emergency brake assist detects when youbrake heavily by measuring the rate atwhich you press the brake pedal. Itprovides maximum braking efficiency aslong as you press the pedal. Emergencybrake assist can reduce stopping distancesin critical situations.
Anti-Lock Brake System
This system helps you maintain steeringcontrol during emergency stops by keepingthe brakes from locking.
If the light does not momentarilyilluminate, continues to flash orremains on when you switch theignition on, the anti-lock brake systemcould be disabled. Have the systemchecked. If the anti-lock brake system isdisabled, normal braking is still effective.
Brake Lamps
See Warning Lamps and Indicators(page 99).
If the light does not momentarilyilluminate, continues to flash orremains on when you switch theignition on or apply the parkingbrake, have the system checked.If the brake warning lampilluminates with the parking brake released,have the system checked immediately.
Note:Indicators vary depending on region.
HINTS ON DRIVING WITH
ANTI-LOCK BRAKES
The anti-lock brake system does noteliminate the risks when:
•You drive too closely to the vehicle infront of you.
•Your vehicle is hydroplaning.
•You take corners too fast.
•The road surface is poor.
Note: If the system activates, the brakepedal could pulse and may travel further.Maintain pressure on the brake pedal. Youmay also hear a noise from the system. Thisis normal.

PRINCIPLE OF OPERATION
The traction control system helps avoiddrive wheel spin and loss of traction.
If your vehicle begins to slide, the systemapplies the brakes to individual wheelsand, when needed, reduces engine powerat the same time. If the wheels spin whenaccelerating on slippery or loose surfaces,the system reduces engine power in orderto increase traction.
USING TRACTION CONTROL
WARNING: Operating your vehiclewith the traction control disabled couldlead to an increased risk of loss of vehiclecontrol, vehicle rollover, personal injuryand death.
The system automatically turns on eachtime you switch the ignition on.
If your vehicle is stuck in mud or snow,switching traction control off may bebeneficial as this allows the wheels to spin.
Note:When you switch traction control off,stability control remains fully active.
Switching the System Off

PRINCIPLE OF OPERATION
WARNING: Vehicle modificationsinvolving braking system, aftermarketroof racks, suspension, steering system,tire construction and wheel and tire sizemay change the handling characteristicsof your vehicle and may adversely affectthe performance of the electronicstability control system. In addition,installing any stereo loudspeakers mayinterfere with and adversely affect theelectronic stability control system. Installany aftermarket stereo loudspeaker asfar as possible from the front centerconsole, the tunnel, and the front seatsin order to minimize the risk of interferingwith the electronic stability controlsensors. Reducing the effectiveness ofthe electronic stability control systemcould lead to an increased risk of loss ofvehicle control, vehicle rollover, personalinjury and death.
WARNING: Remember that evenadvanced technology cannot defy thelaws of physics. It’s always possible tolose control of a vehicle due toinappropriate driver input for theconditions. Aggressive driving on anyroad condition can cause you to losecontrol of your vehicle increasing the riskof personal injury or property damage.Activation of the electronic stabilitycontrol system is an indication that atleast some of the tires have exceededtheir ability to grip the road; this couldreduce the operator’s ability to controlthe vehicle potentially resulting in a lossof vehicle control, vehicle rollover,personal injury and death. If yourelectronic stability control systemactivates, SLOW DOWN.
The system automatically turns on eachtime you switch the ignition on.
If a fault occurs in either the stabilitycontrol or the traction control system, youmay experience the following conditions:
•The stability and traction control lightilluminates steadily.
•The stability control and tractioncontrol systems do not enhance yourvehicle's ability to maintain traction ofthe wheels.
If a driving condition activates either thestability control or the traction controlsystem you may experience the followingconditions:
•The stability and traction control lightflashes.
•Your vehicle slows down.
•Reduced engine power.
•A vibration in the brake pedal.
•The brake pedal is stiffer than usual.
•If the driving condition is severe andyour foot is not on the brake, the brakepedal may move as the system applieshigher brake force.
The stability control system has severalfeatures built into it to help you maintaincontrol of your vehicle:
Electronic Stability Control
The system enhances your vehicle’s abilityto prevent skids or lateral slides byapplying brakes to one or more of thewheels individually and, if necessary,reducing engine power.
Roll Stability Control
The system enhances your vehicle’s abilityto prevent rollovers by detecting yourvehicle’s roll motion and the rate at whichit changes by applying the brakes to oneor more wheels individually.
