If the service engine soon indicator remainson, have your vehicle serviced at the firstavailable opportunity. Although somemalfunctions detected by the OBD-II may nothave symptoms that are apparent, continueddriving with the service engine soon indicatoron can result in increased emissions, lowerfuel economy, reduced engine andtransmission smoothness and lead to morecostly repairs.
Readiness for Inspection andMaintenance (I/M) Testing
Some state and provincial and localgovernments may haveInspection/Maintenance (I/M) programs toinspect the emission control equipment onyour vehicle. Failure to pass this inspectioncould prevent you from getting a vehicleregistration.
If the service engine soon indicatoris on or the bulb does not work,your vehicle may need service.See On-Board Diagnostics.
Your vehicle may not pass the I/M test if theservice engine soon indicator is on or notworking properly (bulb is burned out), or ifthe OBD-II system has determined that someof the emission control systems have notbeen properly checked. In this case, thevehicle is not ready for I/M testing.
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 the vehicleis not ready for I/M testing. To determine ifthe vehicle is ready for I/M testing, turn theignition key to the on position for 15 secondswithout cranking the engine. If the serviceengine soon indicator blinks eight times, itmeans that the vehicle is not ready for I/Mtesting; if the service engine soon indicatorstays on solid, it means that your vehicle isready for 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, youcan perform the following driving cycleconsisting of mixed city and highway driving:
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 least eighthours with the ignition off. Then, start thevehicle and complete the above drivingcycle. The vehicle must warm up to itsnormal operating temperature. Oncestarted, do not turn off the vehicle untilthe above driving cycle is complete.
If the vehicle is still not ready for I/M testing,you need to repeat the above driving cycle.

SelectShift™ Automatic Transmission
Your vehicle is equipped with a SelectShiftAutomatic transmission. The SelectShiftAutomatic transmission gives you the abilityto change gears up or down, without aclutch, as desired.
In order to prevent the engine from runningat too low of an RPM, which may cause it tostall, SelectShift still automatically makessome downshifts if it has determined thatyou have not downshifted in time. AlthoughSelectShift makes some downshifts for you,it still allows you to downshift at any time aslong as the SelectShift determines thatdamage to the engine does not occur fromover-revving.
Note:Engine damage may occur if youmaintain excessive engine revving withoutshifting.
SelectShift does not automatically upshift,even if the engine is approaching the RPMlimit. It must be shifted manually by pressingthe + paddle.
Pull the + paddle on the steering wheel toactivate SelectShift.
•Pull the right paddle (+) to upshift.
•Pull the left paddle (–) to downshift.
SelectShift in drive (D):
Provides a temporary manual mode forperforming more demanding maneuverswhere extra control of gear selection isrequired (for example, when towing, downhilldriving or overtaking). This mode holds aselected gear for a temporary period of timedependent on driver inputs (for example,steering or accelerator pedal input).
In SelectShift mode, the instrument clusterdisplays your currently selected gear. If yourequest a gear, but it is not available due tovehicle conditions, low speed, too highengine speed for requested gear selection,the current gear briefly flashes.
Note:At full accelerator pedal travel, thetransmission downshifts for maximumperformance.
Note:In low traction conditions, you can pullaway in second gear using SelectShift. Toperform this operation, select drive (D) andpress the + paddle until 2 is displayed on thecluster. Your vehicle is now ready to movein 2nd gear.

Note:The information display could showmessages during 4WD operation. SeeInformation Messages (page 124).
2H - 4X2
2H turns on when you select NORMAL orCONSERVE. Power is delivered to the rearwheels only. This mode is appropriate fornormal on-road driving on dry pavement andprovides the best fuel economy.
4A - 4X4 Auto
4A turns on when you select EXCITE,NORMAL 4x4 AUTO or SLIPPERY. Itprovides electronically controlled four-wheeldrive with power delivered to all four wheels,as required, for increased traction. 4A iscalibrated in conjunction with Drive Mode.4A in EXCITE is less aggressively tuned andis appropriate for dry road surfaces. 4A inNORMAL 4x4 AUTO is appropriate for allon-road driving conditions, such as dry roadsurfaces, wet pavement, light snow or gravel.4A in SLIPPERY is more aggressively tunedand is appropriate for slippery surfaces, suchas light snow or gravel.
4H - 4X4 High
4H turns on when you select DEEPCONDITIONS. It provides electronicallylocked four-wheel drive power to both thefront and rear wheels for use in off-road orwinter conditions such as deep snow, sandor mud. This mode is not for use on drypavement.
4L - 4X4 Low
4L turns on when you select SLOW CLIMB.It provides electronically locked four-wheeldrive power to both the front and rear wheelsfor use on low traction surfaces, but does sowith additional gearing for increased torquemultiplication. Intended only for off-roadapplications such as deep sand, steepgrades or pulling heavy objects. 4L does notengage when your vehicle is moving above3 mph (5 km/h); this is normal and should beno reason for concern.
Shifting Between 4WD System Modes
Note:Momentarily releasing the acceleratorpedal when a shift in progress messagedisplays improves engagement anddisengagement performance.
Note:Do not perform this operation if therear wheels are slipping.
Note:You may hear some noise as thesystem shifts or engages; this is normal.

Basic Operating Principles
•Do not use SLIPPERY, DEEPCONDITIONS or SLOW CLIMB on dry,hard surfaced roads. Doing so producesexcessive noise, increases tire wear andmay damage drive components. The 4X4system in these modes is only intendedfor consistently slippery or loosesurfaces.
•Drive slower in strong crosswinds whichcan affect the normal steeringcharacteristics of your vehicle.
•When driving your vehicle on surfacesmade slippery by loose sand, water,gravel, snow or ice, proceed with care.
If Your Vehicle leaves the Road
If your vehicle leaves the road, reduce yourvehicle speed and avoid severe braking.When your vehicle speed has been reducedease your vehicle back onto the road. Donot turn the steering wheel sharply whenreturning your vehicle to the road.
It may be safer to stay on the shoulder of theroad and slow down gradually beforereturning to the road. You may lose controlif you do not slow down or if you turn thesteering wheel too sharply or abruptly.
It may be less risky to strike small objects,such as freeway reflectors, with minordamage to your vehicle rather than attempta sudden return to the road which couldcause your vehicle to slide sideways out ofcontrol or roll over. Remember, your safetyand the safety of others should be yourprimary concern.
If your vehicle gets stuck
WARNING: Do not spin the wheelsat over 34 mph (55 km/h). The tires mayfail and injure a passenger or bystander.
Note:Do not rock your vehicle if the engineis not at normal operating temperature,damage to the transmission may occur.
Note:Do not rock your vehicle for more thana minute, damage to the transmission andtires may occur or the engine may overheat.
If your vehicle gets stuck in mud or snow itmay be rocked out by shifting betweenforward and reverse gears, stoppingbetween shifts, in a steady pattern. Presslightly on the accelerator in each gear.
Emergency Maneuvers
In an unavoidable emergency situationwhere a sudden sharp turn must be made,remember to avoid over-driving your vehicle(i.e. turn the steering wheel only as rapidlyand as far as required to avoid theemergency). Excessive steering can resultin loss of vehicle control. Apply smoothpressure to the accelerator pedal or brakepedal when changes in vehicle speed arerequired. Avoid abrupt steering, accelerationand braking. This could result in an increasedrisk of vehicle roll over, loss of vehicle controland personal injury. Use all available roadsurface to bring your vehicle to a safedirection of travel.
In the event of an emergency stop, avoidskidding the tires and do not attempt anysharp steering wheel movements.

When climbing a steep slope or hill, start ina lower gear rather than downshifting to alower gear from a higher gear once theascent has started. This reduces strain onthe engine and the possibility of stalling.
If your vehicle stalls, do not try to turn aroundbecause this could cause vehicle roll over.It is better to reverse back to a safe location.
Apply just enough power to the wheels toclimb the hill. Too much power causes thetires to slip, spin or lose traction, resulting inloss of vehicle control.
Descend a hill in the same gear you woulduse to climb up the hill to avoid excessivebrake application and brake overheating. Donot descend in neutral. Disengage overdriveor move the transmission selector lever to alower gear. When descending a steep hill,avoid sudden hard braking as you could losecontrol. The front wheels have to be turningin order to steer your vehicle.
If your vehicle has anti-lock brakes, apply thebrakes steadily. Do not pump the brakes.
Driving on Snow and Ice
WARNING: If you are driving inslippery conditions that require tire chainsor cables, then it is critical that you drivecautiously. Keep speeds down, allow forlonger stopping distances and avoidaggressive steering to reduce the chancesof a loss of vehicle control which can leadto serious injury or death. If the rear endof your vehicle slides while cornering, steerin the direction of the slide until you regaincontrol of your vehicle.
Note:Excessive tire slippage can causetransmission damage.
Four-wheel drive vehicles have advantagesover two-wheel drive vehicles in snow andice but can skid like any other vehicle.Should you start to slide when driving onsnowy or icy roads, turn the steering wheelin the direction of the slide until you regaincontrol.
Avoid sudden applications of power andquick changes of direction on snow and ice.Apply the accelerator slowly and steadilywhen starting from a full stop.
Avoid sudden braking. Although a four-wheeldrive vehicle may accelerate better than atwo-wheel drive vehicle in snow and ice, itdoes not stop any faster as braking occursat all four wheels. Do not becomeoverconfident in any road condition.
Make sure you allow sufficient distancebetween you and other vehicles for stopping.Drive slower than usual and consider usingone of the lower gears. In emergencystopping situations, apply the brake steadily.Do not pump the brake pedal. See Hints onDriving With Anti-Lock Brakes (page 226).
