Remote Vehicle Start
This feature allows you to start the engine from outsideof the vehicle. It may also start up the vehicle's heatingor air conditioning systems and rear window defogger.Normal operation of the system will return after the keyis turned to the ON/RUN position.
During a remote start, the climate control system willdefault to a heating or cooling mode depending on theoutside temperatures.
During a remote start, if your vehicle has an automaticclimate control system and heated seats, the heatedseats will turn on during colder outside temperaturesand will shut off when the key is turned to ON/RUN.If your vehicle does not have an automatic climatecontrol system, during remote start, you will need tomanually turn the heated seats on and off. SeeHeatedand Cooled Seatso n p a g e 2!5for additionalinformation.
Laws in some communities may restrict the use ofremote starters. For example, some laws may require aperson using the remote start to have the vehicle inview when doing so. Check local regulations for anyrequirements on remote starting of vehicles.
Do not use the remote start feature if your vehicle is lowon fuel. Your vehicle may run out of fuel.

Engine Coolant Heater
The engine coolant heater can provide easier startingand better fuel economy during engine warm-up in coldweather conditions at or below!18°C (0°F). Vehicleswith an engine heater should be plugged in at leastfour hours before starting. An internal thermostat inthe plug-end of the cord may exist which will preventengine coolant heater operation at temperaturesabove!18°C (0°F).
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.The cord is secured to the Engine CompartmentFuse Block with a clip. Carefully remove the wiretie which secures the electrical cord. Do not cut theelectrical cord.
3. Plug the cord into a normal, grounded 110-voltAC outlet.
{WARNING:
Plugging the cord into an ungrounded outlet could
cause an electrical shock. Also, the wrong kind of
extension cord could overheat and cause a fire.
You could be seriously injured. Plug the cord into
a properly grounded three-prong 110-volt AC
outlet. If the cord will not reach, use a heavy-duty
three-prong extension cord rated for at least
15 amps.
4. Before starting the engine, be sure to unplug andstore the cord as it was before to keep it away frommoving engine parts. If you do not, it could bedamaged.
The length of time the heater should remain plugged independs on several factors. Ask a dealer/retailer in thearea where you will be parking the vehicle for the bestadvice on this.

Active Fuel Management™
Vehicles with V8 engines may have Active FuelManagement™. This system allows the engine tooperate on either all or half of its cylinders, dependingon the driving conditions.
When less power is required, such as cruising at aconstant vehicle speed, the system will operate in thehalf cylinder mode, allowing the vehicle to achievebetter fuel economy. When greater power demands arerequired, such as accelerating from a stop, passing,or merging onto a freeway, the system will maintainfull-cylinder operation.
If the vehicle has an Active Fuel Management™indicator, seeDIC Operation and Displaysonpage 4!41for more information on using this display.
Automatic Transmission Operation
If the vehicle is a Two-mode Hybrid, see the Two-modeHybrid manual for more information.
The vehicle has a Hydra-Matic®6L80 automatictransmission, and has an electronic shift positionindicator within the instrument panel cluster.The electronic shift position indicator displays whenthe shift lever is moved out of P (Park).
There are several different positions for the shift lever.
P (Park) :This position locks the rear wheels. It is thebest position to use when you start the engine becausethe vehicle cannot move easily.
3-32

N (Neutral) :In this position, the engine does notconnect with the wheels. To restart when you arealready moving, use N (Neutral) only. Also, useN (Neutral) when the vehicle is being towed.
{WARNING:
Shifting into a drive gear while the engine is
running at high speed is dangerous. Unless your
foot is firmly on the brake pedal, the vehicle could
move very rapidly. You could lose control and hit
people or objects. Do not shift into a drive gear
while the engine is running at high speed.
Notice:Shifting out of P (Park) or N (Neutral) withthe engine running at high speed may damage thetransmission. The repairs would not be covered bythe vehicle warranty. Be sure the engine is notrunning at high speed when shifting the vehicle.
D (Drive) :This position is for normal driving. It providesthe best fuel economy. If you need more power forpassing, and you are:
.Going less than about 35 mph (55 km/h), push theaccelerator pedal about halfway down.
.Going about 35 mph (55 km/h) or more, push theaccelerator all the way down.
By doing this, the vehicle shifts down to the next gearand has more power.
D (Drive) can be used when towing a trailer, carrying aheavy load, driving on steep hills, or for off-road driving.You may want to shift the transmission to a lower gearselection if the transmission shifts too often.
Downshifting the transmission in slippery roadconditions could result in skidding, see Skidding underLoss of Control on page 6!12.
M (Manual Mode) :This position lets drivers selectthe range of gears appropriate for current drivingconditions. See Driver Shift Control (DSC) later inthis section.
Notice:Spinning the tires or holding the vehicle inone place on a hill using only the accelerator pedalmay damage the transmission. The repair will not becovered by the vehicle warranty. If you are stuck, donot spin the tires. When stopping on a hill, use thebrakes to hold the vehicle in place.
The vehicle has a shift stabilization feature thatadjusts the transmission shifting to the currentdriving conditions in order to reduce rapid upshiftsand downshifts. This shift stabilization feature isdesigned to determine, before making an upshift, ifthe engine will be able to maintain vehicle speed by

When the Light Flashes First and Then is
On Steady
This indicates that there may be a problem with the TirePressure Monitor System. The light flashes for about aminute and stays on steady for the remainder of theignition cycle. This sequence repeats with every ignitioncycle. SeeTire Pressure Monitor Operationonpage 7!68for more information.
Malfunction Indicator Lamp
Check Engine Light
A computer system called OBD II (On-BoardDiagnostics-Second Generation) monitors operationof the fuel, ignition, and emission control systems.It ensures that emissions are at acceptable levels forthe life of the vehicle, helping to produce a cleanerenvironment.
This light should come onwhen the ignition is on,but the engine is notrunning, as a check toshow it is working. If itdoes not, have the vehicleserviced by your dealer/retailer.
If the check engine light comes on and stays on, whilethe engine is running, this indicates that there is anOBD II problem and service is required.
Malfunctions often are indicated by the system beforeany problem is apparent. Being aware of the light canprevent more serious damage to the vehicle. Thissystem assists the service technician in correctlydiagnosing any malfunction.
Notice:If the vehicle is continually driven with thislight on, after a while, the emission controls mightnot work as well, the vehicle's fuel economy mightnot be as good, and the engine might not run assmoothly. This could lead to costly repairs thatmight not be covered by the vehicle warranty.
Notice:Modifications made to the engine,transmission, exhaust, intake, or fuel system of thevehicle or the replacement of the original tires withother than those of the same Tire PerformanceCriteria (TPC) can affect the vehicle's emissioncontrols and can cause this light to come on.Modifications to these systems could lead to costlyrepairs not covered by the vehicle warranty. Thiscould also result in a failure to pass a requiredEmission Inspection/Maintenance test. SeeAccessories and Modifications on page 7!4.

This light comes on during a malfunction in one oftwo ways:
Light Flashing :A misfire condition has been detected.A misfire increases vehicle emissions and coulddamage the emission control system on the vehicle.Diagnosis and service might be required.
To prevent more serious damage to the vehicle:
.Reduce vehicle speed.
.Avoid hard accelerations.
.Avoid steep uphill grades.
.If towing a trailer, reduce the amount of cargobeing hauled as soon as it is possible.
If the light continues to flash, when it is safe to do so,stop the vehicle. Find a safe place to park the vehicle.Turn the key off, wait at least 10 seconds, and restartthe engine. If the light is still flashing, follow theprevious steps and see your dealer/retailer for serviceas soon as possible.
Light On Steady :An emission control systemmalfunction has been detected on the vehicle.Diagnosis and service might be required.
An emission system malfunction might be corrected bydoing the following:
.Make sure the fuel cap is fully installed. SeeFillingthe Tankon page 7!11. The diagnostic systemcan determine if the fuel cap has been left off or
improperly installed. A loose or missing fuel capallows fuel to evaporate into the atmosphere. A fewdriving trips with the cap properly installed shouldturn the light off.
.If the vehicle has been driven through a deeppuddle of water, the vehicle's electrical systemmight be wet. The condition is usually correctedwhen the electrical system dries out. A few drivingtrips should turn the light off.
.Make sure to fuel the vehicle with quality fuel.Poor fuel quality causes the engine not to run asefficiently as designed and can cause: stalling afterstart-up, stalling when the vehicle is changed intogear, misfiring, hesitation on acceleration,or stumbling on acceleration. These conditionsmight go away once the engine is warmed up.
If one or more of these conditions occurs, changethe fuel brand used. It will require at least one fulltank of the proper fuel to turn the light off.
SeeGasoline Octane on page 7!8.
If none of the above have made the light turn off, yourdealer/retailer can check the vehicle. The dealer/retailerhas the proper test equipment and diagnostic tools to fixany mechanical or electrical problems that might havedeveloped.

Highbeam On Light
This light comes on whenthe high-beam headlampsare in use.
SeeHeadlamp High/Low-Beam Changero n p a g e 4!5for more information.
Tow/Haul Mode Light
For vehicles with the tow/haul mode feature, thislight comes on when theTow/Haul mode has beenactivated.
For more information, seeTow/Haul Modeonpage 3!36.
Fuel Gage
When the ignition is on,the fuel gage shows abouthow much fuel the vehiclehas left in the tank.
An arrow on the fuel gage indicates the side of thevehicle the fuel door is on.
The gage will first indicate empty before the vehicle isout of fuel, but the vehicle's fuel tank should befilled soon.
