1.Connect the positive (+) jumper cableto the positive (+) prong (A) of thedischarged battery.
2. Connect the other end of the positive(+) cable to the positive (+) terminalof the assisting battery.
3. Connect the negative (-) cable to thenegative (-) terminal of the assistingbattery.
4. Make the final connection of thenegative (-) cable to the negative (-)prong (B) of your vehicle.
Note:Do not attach the negative (-) cableto fuel lines, engine rocker covers, the intakemanifold or electrical components. Theseitems should not be considered groundingpoints.
WARNING
Never connect the negative end ofthe cable to the negative (-) terminalof the discharged battery. A sparkmay cause an explosion of the gases thatsurround the battery. Always use thenegative prong as a grounding point.
Make sure that the cables are clear of fanblades, belts, the moving parts of bothengines, or any fuel delivery system parts.
Jump Starting
1.Start the booster vehicle and press theaccelerator pedal moderately.
2. Start the disabled vehicle. Check theinstrument cluster for the Ready toDrive light as the gasoline engine maynot start, but the electric motor maybe running.
3.Once you start the disabled vehicle, runboth vehicles for an additional threeminutes before disconnecting thejumper cables.
Removing the Jumper Cables
Remove the jumper cables in the reverseorder that they were connected.
Note:In the illustration, the vehicle on thebottom is used to designate the assisting(boosting) battery.

FUSE SPECIFICATION CHART
Pre-Fuse Box
Your vehicle has a pre-fuse box attachedto the power distribution box. There is asecond pre-fuse box attached to the12-volt battery terminal in the rear of yourvehicle. They contain high-current fuses.If you need to replace one of these fuses,see an authorized dealer.
Power Distribution Box
WARNINGS
Always disconnect the battery beforeservicing high current fuses.
WARNINGS
To reduce risk of electrical shock,always replace the cover to thepower distribution box beforereconnecting the battery or refilling fluidreservoirs.
The power distribution box is located inthe engine compartment. It hashigh-current fuses that protect yourvehicle's main electrical systems fromoverloads.
If you disconnect and reconnect thebattery, you will need to reset somefeatures. See Changing the 12V Battery(page 233).
Lift the release lever at the rear of the coverto remove it.

CHANGING A FUSE
Fuses
WARNING
Always replace a fuse with one thathas the specified amperage rating.Using a fuse with a higher amperagerating can cause severe wire damage andcould start a fire.If electrical components in the vehicle arenot working, a fuse may have blown. Blownfuses are identified by a broken wire withinthe fuse. Check the appropriate fusesbefore replacing any electricalcomponents.

ENGINE COOLANT CHECK
WARNINGS
To reduce the risk of personal injury,make sure the engine is cool beforeunscrewing the coolant pressurerelief cap. The cooling system is underpressure. Steam and hot liquid can comeout forcefully when you loosen the capslightly.
Do not put coolant in the windshieldwasher fluid reservoir. If sprayed onthe windshield, coolant could makeit difficult to see through the windshield.
To reduce the risk of personal injury,make sure the engine is cool beforeunscrewing the coolant pressurerelief cap. The cooling system is underpressure. Steam and hot liquid can comeout forcefully when you loosen the capslightly.
Do not add coolant further than theMAX mark.
Your vehicle has two separate coolingsystems. One for cooling the engine and aseparate system for cooling the invertersystem controller that is specific to thehybrid operating system. The two systemsoperate similarly, with the inverter systemcontroller cooling system generallyoperating at a lower temperature andpressure.
When the engine is cold, check theconcentration and level of the coolant atthe intervals listed in the scheduledmaintenance information. See ScheduledMaintenance (page 441).
Note:Make sure that the coolant level isbetween the MIN and MAX marks on thecoolant reservoir.
Note: Coolant expands when it is hot. Thelevel may extend beyond the MAX mark.
Maintain coolant concentration within48% to 50%, which equates to a freezepoint between -30°F (-34°C) and -34°F(-37°C). Coolant concentration should bechecked using a refractometer. We do notrecommend the use of hydrometers orcoolant test strips for measuring coolantconcentration.
Adding Coolant
WARNING
Never remove the coolant reservoircap when the engine is running orhot.
Note:Automotive fluids are notinterchangeable. Do not use coolant orwindshield washer fluid outside of itsspecified function and vehicle location.
Note: Do not use stop leak pellets, coolingsystem sealants, or non-specified additivesas they can cause damage to the enginecooling or heating systems. Resultingcomponent damage may not be covered bythe vehicle Warranty.
It is very important to use predilutedcoolant approved to the correctspecification in order to avoid plugging thesmall passageways in the engine coolingsystem. See Capacities andSpecifications (page 286). Do not mixdifferent colors or types of coolant in yourvehicle. Mixing of engine coolants or usingan incorrect coolant may harm the engineor cooling system components and maynot be covered by the vehicle Warranty.

Maintenance
Severe Climates
If you drive in extremely cold climates:
•It may be necessary to increase thecoolant concentration above 50%.
•A coolant concentration of 60%provides improved freeze pointprotection. Coolant concentrationsabove 60% decrease the overheatprotection characteristics of thecoolant and may cause enginedamage.
If you drive in extremely hot climates:
•You can decrease the coolantconcentration to 40%.
•Coolant concentrations below 40%decrease the freeze and corrosionprotection characteristics of thecoolant and may cause enginedamage.
Vehicles driven year-round in non-extremeclimates should use prediluted coolant foroptimum cooling system and engineprotection.
Coolant Change
At specific mileage intervals, as listed inthe scheduled maintenance information,the coolant should be changed. Addprediluted coolant approved to the correctspecification. See Capacities andSpecifications (page 282).
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
If the engine begins to overheat, thecoolant temperature gauge moves towardthe 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.
Continued operation increases the enginetemperature, causing the engine tocompletely shut down. Your steering andbraking effort increases in this situation.
When the engine temperature cools, youcan re-start the engine. Have your vehiclechecked as soon as possible to minimizeengine damage.
When Fail-Safe Mode Is Activated
WARNINGS
Fail-safe mode is for use duringemergencies only. Operate yourvehicle in fail-safe mode only as longas necessary to bring your vehicle to restin a safe location and seek immediaterepairs. When in fail-safe mode, yourvehicle will have limited power, will not beable to maintain high-speed operation, andmay completely shut down withoutwarning, potentially losing engine power,power steering assist, and power brakeassist, which may increase the possibilityof a crash resulting in serious injury.
Never remove the coolant reservoircap when the engine is running orhot.
