Please consult your warranty informationfor complete details.
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 152).
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 malfunctions
present, 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 on

position 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.

50 mph (80 km/h)5 – 6
Brake-Shift Interlock
WARNINGS
Do not drive your vehicle until youverify that the brake lamps areworking.
When doing this procedure, you needto take the transmission out of park(P) which means your vehicle canroll freely. To avoid unwanted vehiclemovement, always fully set the parkingbrake prior to doing this procedure. Usewheels chocks if appropriate.
If the parking brake is fully released,but the brake warning lamp remainsilluminated, the brakes may not beworking properly. Have your vehiclechecked as soon as possible.
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 233).
If the fuse is not blown and the brakelamps are working properly, the followingprocedure will allow you to move thegearshift lever from park (P):
Column-shifter
1. Apply the parking brake. Turn theignition key to the off position, thenremove the key.
2. Move the steering column to the fulldown and full rearward position(toward the driver’s seat).

In the event of an emergency stop, avoidskidding the tires and do not attempt anysharp steering wheel movements.
If your vehicle goes from one type ofsurface to another (i.e. from concrete togravel) there will be a change in the wayyour vehicle responds to a maneuver (i.e.steering, acceleration or braking).
Sand
When driving over sand, try to keep all fourwheels on the most solid area of the trail.Avoid reducing the tire pressures but shiftto a lower gear and drive steadily throughthe terrain. Apply the accelerator slowlyand avoid excessive wheel slip.
Avoid driving at excessive speeds, thiscauses vehicle momentum to work againstyou and your vehicle could become stuckto the point that assistance may berequired from another vehicle. Remember,you may be able to back out the way youcame if you proceed with caution.
Mud and Water
Note:Driving through deep water maydamage the vehicle.
If you must drive through high water, driveslowly. Traction or brake capability maybe limited.
When driving through water, determine thedepth and avoid water higher than thebottom of the hubs. If the ignition systemgets wet, your vehicle may stall.
Once through water, always try the brakes.Wet brakes do not stop your vehicle aseffectively as dry brakes. Drying can beimproved by applying light pressure to thebrake pedal while moving slowly.
Be cautious of sudden changes in vehiclespeed or direction when you are driving inmud. Even 4WD vehicles can lose tractionin slick mud. As when you are driving oversand, apply the accelerator slowly andavoid spinning your wheels. If the vehicledoes slide, steer in the direction of the slideuntil you regain control of the vehicle.
If the transmission, transfer case or frontaxle are submerged in water, their fluidsshould be checked and changed, ifnecessary.
If the front or rear axle is submerged inwater, the axle lubricant should bereplaced.
After driving through mud, clean off residuestuck to rotating driveshafts and tires.Excess mud stuck on tires and rotatingdriveshafts causes an imbalance thatcould damage drive components.

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 anauthorized dealer should check them. If thevehicle has continuous vibration or shudderin the steering wheel while braking, anauthorized dealer should check your vehicle.
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 270).
See Warning Lamps andIndicators (page 87).
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. 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 the nearest authorized dealer.
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.
This lamp momentarilyilluminates when you switch theignition on. If the light does notilluminate during start up, remains on orflashes, the anti-lock braking system maybe disabled. Have the system checked byan authorized dealer. If the anti-lock brakesystem is disabled, normal braking is stilleffective.
If the brake warning lampilluminates with the parkingbrake released, have your brakesystem serviced immediately.
HINTS ON DRIVING WITH
ANTI-LOCK BRAKES
Note:When the system is operating, thebrake pedal may pulse and may travelfurther. Maintain pressure on the brakepedal. You may also hear a noise from thesystem. This is normal.
The anti-lock braking system will 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.

PARKING BRAKE
WARNING
Always set the parking brake fullyand make sure the transmission isplaced in park (P). Failure to set theparking brake and engage park could resultin vehicle roll-away, property damage orbodily injury. Turn the ignition to the lockposition and remove the key whenever youleave your vehicle.
Apply the parking brake whenever yourvehicle is parked. Press the pedaldownward to set the parking brake. Thebrake warning lamp in the instrumentcluster will illuminate and remainsilluminated until the parking brake isreleased.
To release, pull the brake release leverlocated at the lower left side of theinstrument panel.
If you are parking your vehicle on a gradeor with a trailer, press and hold the brakepedal down, then set the parking brake.There may be a little vehicle movement asthe parking brake sets to hold the vehicle'sweight. This is normal and should be noreason for concern. If needed, press andhold the service brake pedal down, thentry reapplying the parking brake. Chock thewheels if required. If the parking brakecannot hold the weight of the vehicle, theparking brake may need to be serviced orthe vehicle may be overloaded.
HILL START ASSIST
WARNINGS
The system does not replace theparking brake. When you leave yourvehicle, always apply the parkingbrake and shift the transmission into park(P) (automatic transmission) or first gear(1) (manual transmission).
WARNINGS
You must remain in your vehicle onceyou have activated the system.
During all times, you are responsiblefor controlling your vehicle,supervising the system andintervening, if required.
If the engine is revved excessively, orif a malfunction is detected, thesystem will be deactivated.
The system makes it easier to pull awaywhen your vehicle is on a slope without theneed to use the parking brake.
When the system is active, your vehicle willremain stationary on the slope for two tothree seconds after you release the brakepedal. This allows you time to move yourfoot from the brake to the acceleratorpedal. The brakes release automaticallywhen the engine has sufficient torque toprevent your vehicle from rolling down thegrade. This is an advantage when pullingaway on a slope, for example from a carpark ramp, traffic lights or when reversinguphill into a parking space.
The system will activate automatically onany slope that will cause significant vehiclerollback. For vehicles with a manualtransmission, you can switch this featureoff using the information display. SeeInformation Displays (page 91). Thesystem will remain on or off depending onhow it was last set.
Note:There is no warning lamp to indicatethe system is either on or off.
Note:If your vehicle is equipped with AutoHold, Hill Start Assist will not be availablewhile Auto Hold is active.

Brakes

Using Hill Start Assist
1. Bring your vehicle to a completestandstill. Keep the brake pedalpressed and select an uphill gear (forexample, first (1) when facing uphill orreverse (R) when facing downhill).
2. If the sensors detect that your vehicleis on a slope, the system will activateautomatically.
3. When you remove your foot from thebrake pedal, your vehicle will remainon the slope without rolling away forabout two or three seconds. This holdtime will automatically be extended ifyou are in the process of driving off.
4. Drive off in the normal manner. Thebrakes will release automatically.
Switching the System On and Off
You can switch this feature on or off if yourvehicle is equipped with a manualtransmission and an information display.See General Information (page 91). Thesystem remembers the last setting whenyou start your vehicle.
If your vehicle is not equipped with amanual transmission and an informationdisplay, you cannot turn the system on oroff. When you switch the ignition on, thesystem automatically turns on.

Brakes

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
The stability and traction controllight illuminates steadily if thesystem detects a failure. Make sureyou did not manually disable the tractioncontrol system using the switch. If thestability control and traction control lightis still illuminating steadily, have thesystem serviced by an authorized dealerimmediately. Operating your vehicle withtraction control disabled could lead to anincreased risk of loss of vehicle control,vehicle rollover, personal injury and 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
The switch for the stability and tractioncontrol system is on the instrument panel.
When you switch the system off, amessage and an illuminated icon appearon the instrument cluster.
Use the switch again to return the tractioncontrol system to normal operation.
Your vehicle may have MyKey restrictionsregarding this feature. See Principle ofOperation (page 47).
System Indicator Lights andMessages
The stability and traction controllight temporarily illuminates onengine start-up and flashes:
•When a driving condition activateseither of the systems.
•If a problem occurs in either of thesystems.
The stability and traction controloff light temporarily illuminateson engine start-up and stays on:
•When you switch the traction controlsystem off.
•When you select an alternative stabilitycontrol mode.
