HYBRID ELECTRIC VEHICLEINFORMATION – FREQUENTLYASKED QUESTIONS
What should I do if the vehicle runs outof fuel and the high voltage battery isout of charge?
Refuel and start your vehicle normally.The engine will recharge the highvoltage battery.
Why does the engine sometimes startat key-on?
The vehicle's computer determines ifan engine start is required at key-on.It starts the engine when necessary forcabin heating, windshield defrost, or ifthe outside temperature is low.
Can I put E15 or E85 in my vehicle, andhow will it affect my fuel economy?
Your hybrid vehicle can use E15 (15%ethanol, 85% gasoline) fuel, but youmay notice slightly reduced fueleconomy because ethanol containsless energy per gallon than gasoline.Your hybrid vehicle is not designed touse E85 (85% ethanol).
Why does it take a long time before theengine shuts down?
There are several reasons the enginestays on for an extended amount oftime when you first start it. Onecommon reason is to make sure thatthe emissions components are warmenough to minimize tailpipe emission.As the climate gets cooler, theengine-on time is extended.
Why does my engine stay on when it isextremely cold outside?
In order to make sure that the climatecontrol system can begin heating thecabin or defrosting the windshield assoon as a driver requests it, the enginecoolant temperature has to be keptsufficiently hot. Keeping the engine onis required to maintain the correctcoolant temperature.

Water alone, without engine coolant, cancause engine damage from corrosion,overheating or freezing.
Do not use the following as a coolantsubstitute, as they can cause enginedamage from overheating or freezing:
•Alcohol.
•Methanol.
•Brine.
•Any coolant mixed with alcohol ormethanol antifreeze.
Do not add extra inhibitors or additives tothe coolant. These can be harmful andcompromise the corrosion protection ofthe coolant.
Severe Climates
If you drive in extremely cold climates, youmay need to increase the coolantconcentration above 50%.
Note:A coolant concentration of 60%provides improved freeze point protection.Coolant concentrations above 60%decrease the overheat protectioncharacteristics of the coolant and couldcause engine damage.
If you drive in extremely hot climates, youmay need to decrease the coolantconcentration to 40%.
Note:A coolant concentration of 40%provides improved overheat protection.Coolant concentrations below 40%decrease the overheat and corrosionprotection characteristics of the coolant andcould cause engine damage.
Coolant Change
WARNING: Do not dispose ofcoolant in the household refuse or thepublic sewage system. Use an authorizedwaste disposal facility.
Change the coolant at specific mileageintervals. Refer to the scheduledmaintenance information. See NormalScheduled Maintenance (page 670).
Note:Dispose of used coolant in theappropriate manner.
Follow your community's regulations andstandards for recycling and disposing ofautomotive fluids.
Fail-Safe Cooling
Fail-safe cooling allows you to temporarilydrive your vehicle before any incrementalcomponent damage occurs. The fail-safedistance depends on ambienttemperature, vehicle load and terrain.
How Fail-Safe Cooling Works
WARNING: If you continue to driveyour vehicle when the engine isoverheating, the engine could stopwithout warning. Failure to follow thisinstruction could result in the loss ofcontrol of your vehicle.
If the engine begins to overheat,the coolant temperature gaugemoves toward the red zone:
A warning lamp illuminates anda message may appear in theinformation display.
If the engine reaches a presetover-temperature condition, the engineautomatically switches to alternatingcylinder operation. Each disabled cylinderacts as an air pump and cools the engine.
When this occurs, your vehicle stilloperates, however:
•Engine power is limited.
•The air conditioning system turns off.

If you replace the battery make sure itmatches the electrical requirements ofyour vehicle.
If you disconnect or replace the batteryand your vehicle has an automatictransmission, it must relearn its adaptivestrategy. Because of this, the transmissionmay shift firmly when first driven. This isnormal operation while the transmissionfully updates its operation to optimumshift feel.
Battery Sensor Reset
When you install a new battery, reset thebattery sensor by doing the following:
1.Switch the ignition on, and leave theengine off.
Note:Complete Steps 2 and 3 within 10seconds.
2.Flash the high beam headlamps fivetimes, ending with the high beams off.
3.Press and release the brake pedal threetimes.
The battery warning lamp flashes threetimes to confirm that the reset issuccessful.
Battery Management System (If
Equipped)
The system monitors battery conditionsand takes actions to extend battery life. Ifexcessive battery drain is detected, thesystem temporarily disables someelectrical systems to protect the battery.
Systems included are:
•Heated rear window.
•Heated seats.
•Climate control.
•Heated steering wheel.
•Audio unit.
•Navigation system.
A message may appear in the informationdisplay to alert you that battery protectionactions are active. This message is only fornotification that an action is taking place,and not intended to indicate an electricalproblem or that the battery requiresreplacement.
After battery replacement, or in somecases after charging the battery with anexternal charger, the battery managementsystem requires eight hours of vehicle sleeptime to relearn the battery state of charge.During this time, your vehicle must remainfully locked with the ignition switched off.
Note:Prior to relearning the battery stateof charge, the battery management systemmay temporarily disable some electricalsystems.
Electrical Accessory Installation
To make sure the battery managementsystem works correctly, do not connect anelectrical device ground connectiondirectly to the battery negative post. Thiscan cause inaccurate measurements ofthe battery condition and potentialincorrect system operation.
Note:If you add electrical accessories orcomponents to the vehicle, it may adverselyaffect battery performance and durability.This may also affect the performance ofother electrical systems in the vehicle.
Remove and Reinstall the Battery
Install a battery approved for use by ourspecifications. See Capacities andSpecifications (page 578).
To disconnect or remove the battery, dothe following:
1.Apply the parking brake and switch theignition off.
2.Switch all electrical equipment off, forexample lights and radio.

TIRE QUALITY GRADES
Tire Quality Grades apply to newpneumatic passenger car tires.The Quality grades can be foundwhere applicable on the tiresidewall between tread shoulderand maximum section width. Forexample: Treadwear 200Traction AA Temperature A.
These Tire Quality Grades aredetermined by standards that theUnited States Department ofTransportation has set.
Tire Quality Grades apply to newpneumatic passenger car tires.They do not apply to deep tread,winter-type snow tires,space-saver or temporary usespare tires, light truck or LT typetires, tires with nominal rimdiameters of 10 to 12 inches orlimited production tires as definedin Title 49 Code of FederalRegulations Part 575.104 (c)(2).
U.S. Department ofTransportation Tire qualitygrades: The U.S. Department ofTransportation requires us to giveyou the following informationabout tire grades exactly as thegovernment has written it.
Treadwear
The treadwear grade is acomparative rating based on thewear rate of the tire when testedunder controlled conditions on aspecified government test course.For example, a tire graded 150would wear 1½ times as well onthe government course as a tiregraded 100. The relativeperformance of tires dependsupon the actual conditions of theiruse, however, and may departsignificantly from the norm due tovariations in driving habits, servicepractices, and differences in roadcharacteristics and climate.
