HYBRID VEHICLE FREQUENTLY ASKED QUESTIONS - HYBRID
ELECTRIC VEHICLE (HEV)
AnswerQuestion
The high voltage battery is electrically isol-ated from the rest of the vehicle when theignition is off. When you switch the ignitionon, the high voltage contacts inside thebattery are closed. This makes the electri-city available to the motor and generatorand allows your vehicle to proceed. Theclicks are the sound of these contacts asthey close and open during start up andshut down.
What are the series of clicks from the cargoarea when I switch the ignition on?
The vehicle's computer determines if anengine start is required at key-on. Silent keystarts the engine if it is necessary for cabinheating, windshield defrost, or if the outsidetemperature is low.
Why does the engine sometimes start atkey-on?
There are several reasons the engine stayson for an extended amount of time whenyou first start it. One common reason is tomake sure that the emission's componentsare warm enough to minimize tailpipeemissions. As the climate gets cooler, thisengine-on time is extended.
Why does it take a long time before theengine shuts down?
In order to make sure that the climatecontrol system can begin heating the cabinor defrosting the windshield as soon as yourequest it, the engine coolant temperaturehas to be kept sufficiently hot. Keeping theengine on is required to maintain the correctcoolant temperature.
Why does my engine stay on when it isextremely cold outside?
Your hybrid vehicle can use E15 fuel (15%ethanol, 85% gasoline), but you couldnotice slightly reduced fuel economybecause ethanol contains less energy pergallon than gasoline. Your hybrid vehicle isnot designed to use E85 (85% ethanol).
Can I put E15 or E85 in my vehicle, and howwill it affect my fuel economy?
The high voltage battery system is designedto last the life of the vehicle and requiresno maintenance.
How long will my high voltage battery last?Does it need maintenance?

If your vehicle runs out of fuel:
•Add a minimum of 1.3 gal (5 L) of fuelto restart the engine.
•You may need to switch the ignitionfrom off to on several times afterrefueling to allow the fuel system topump the fuel from the tank to theengine. When restarting, cranking timetakes a few seconds longer thannormal.
Note:If your vehicle is on a steep slope,more fuel may be required.
Filling a Portable Fuel Container
WARNING: Flow of fuel through afuel pump nozzle can produce staticelectricity. This can cause a fire if you arefilling an ungrounded fuel container.
Use the following guidelines to avoidelectrostatic charge build-up, which canproduce a spark, when filling anungrounded fuel container:
•Only use an approved fuel container totransfer fuel to your vehicle. Place thecontainer on the ground when filling it.
•Do not fill a fuel container when it isinside your vehicle (including the cargoarea).
•Keep the fuel pump nozzle in contactwith the fuel container when filling it.
•Do not use a device that holds the fuelpump nozzle lever in the fill position.
Adding Fuel From a Portable FuelContainer
WARNING: Do not insert the nozzleof a fuel container or an aftermarketfunnel into the fuel filler neck. This maydamage the fuel system filler neck or itsseal and cause fuel to run onto theground.
WARNING: Do not try to pry openor push open the capless fuel systemwith foreign objects. This could damagethe fuel system and its seal and causeinjury to you or others.
WARNING: Do not dispose of fuelin the household refuse or the publicsewage system. Use an authorized wastedisposal facility.
When refueling the vehicle fuel tank froma fuel container, use the fuel filler funnelincluded with your vehicle. See Fuel FillerFunnel Location (page 183).

PRINCIPLE OF OPERATION
This system is a proactive system. It hasthe ability to anticipate wheel slip andtransfer torque to the front 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 informationdisplay.
USING FOUR-WHEEL DRIVE
WARNING: Vehicles with a highercenter of gravity (utility and four-wheeldrive vehicles) handle differently thanvehicles with a lower center of gravity(passenger cars). Avoid sharp turns,excessive speed and abrupt steering inthese vehicles. Failure to drive cautiouslyincreases the risk of losing control of yourvehicle, vehicle rollover, personal injuryand death.
The intelligent 4WD system continuouslymonitors vehicle conditions and adjuststhe power distribution between the frontand rear wheels. It combines transparentall-surface operation with highly capablefour-wheel drive.
The 4WD system is always active andrequires no driver input. It is capable ofhandling all road conditions includingstreet and highway driving as well asoff-road and winter driving. You canoptimize more 4WD control by selectingdifferent drive modes. See Selecting aDrive Mode (page 273).
Note:A warning message displays in theinformation display when a 4WD systemfault is present. See InformationMessages (page 119). A 4WD system faultcauses the 4WD system to default torear-wheel drive only mode. When thiswarning message is displayed, have yourvehicle serviced at an authorized dealer.
Note:A warning message displays in theinformation display if the 4WD systemoverheats. See Information Messages(page 119). This condition could occur if thevehicle is operated in extreme conditionswith excessive wheel slip, such as deepsand. To resume normal 4WD function assoon as possible, stop the vehicle in a safelocation and stop the engine for at least 10minutes. After the engine is restarted andthe 4WD system is adequately cooled, thewarning message turns off and normal 4WDfunction returns.
Operating Four-Wheel Drive (4WD)Vehicles With Spare Tires
Do not use a different size spare tire otherthan the tire provided. If the mini-spare tireis installed, the 4WD system will disableand enter rear-wheel drive only mode toprotect driveline components. Somelimited 4WD traction could be provided ifthe mini-spare is installed on one of thefront wheels. If you are in driving conditionswhere limited 4WD traction is neededwhile the mini-spare is installed, it isrecommended the mini-spare be installedon the front axle. See InformationMessages (page 119).
If the mini-spare is installed, this conditionis indicated by a warning in the informationdisplay. If there is a warning message inthe information display from using thespare tire, this indicator should turn offafter reinstalling or replacing the normalroad tire and cycling the ignition off andon. We recommended reinstalling or
