Table of ContentsPart: 1Vehicle DescriptionIDENTIFYING A HONDA HYBRIDThe Insight can be identified by its aerodynamicshape and by the name Insight and a hybrid badgeon the rear of the vehicle. The 2000-2006 modelshave rear fender skirts, whereas later models do not.All Honda Insights have an aerodynamic shape. Earlymodels (top above) have two doors, and newer models(e.g., directly above) have four.Except for a few minor differences in equipment,such as a roof antenna, there is very little differencein the exterior or interior appearance of the Civic andAccord hybrids compared to those of their gasolinepowered counterparts.Like the Civic Hybrid, above, all Honda hybrids otherthan the Insight and the CR-Z look essentially the sameas their conventional counterparts.The CR-Z is a two-door, two-passenger sports car.The two-door CR-Z has a sportier appearance thanHonda’s other hybrid vehicles.The easiest way to identify a hybrid is by the wordon the rear of the vehicle. If the wordhybrid is not visible on the rear of a vehicle, due todamage for example, the presence of orange cablesunder the hood, or orange shielding under the car,would also identify the vehicle as a hybrid.Orange cables under the hood, or orange shieldingbolted to the undercarriage of a Honda tell you thevehicle is a hybrid.2

Table of ContentsPart: 1Vehicle DescriptionH I G H - VO LTA G E B AT T E R Y MO D U L E SThe electric motors in all Honda hybrid models except the2012 Civic hybrid are powered by a nickel-metal-hydride(NiMH) battery module. This type of battery contains groups,or “sticks,” of 1.2-volt cells, each about the size of a D-cellbattery. The number of cells varies by vehicle model, andtotal voltages range from 100-160 volts.HV BatteryModuleSingle HVBattery“Stick”SingleHV CellD-CellBatteryThe electric motor in the 2012 Civic hybrid is powered by alithium ion (Li-Ion) battery module. This battery contains fourgroups, or “stacks,” of ten 3.6-volt cells, each a little largerthan a typical cell phone. The total voltage is 144 volts, verysimilar to the NiMH batteries that power other Honda hybrids.Since both types of battery modules are recharged whenevera Honda hybrid vehicle decelerates, neither ever needsexternal charging.One of FourBattery “Stacks”H I G H - VO LTA G E B AT T E R Y B OXEach high-voltage battery module is stored in a sturdy box,such as the one shown here with the lid removed. The boxcontains other important components which, together withthe battery, make up the Intelligent Power Unit (IPU). Allcomponents inside the battery box are completely insulatedOther High-VoltageComponentsHigh-VoltageBattery Moduleand isolated from the vehicle body.For maximum safety, the battery box is positioned in the rearof the vehicle where it is well-protected from potential damagein a collision.4

Table of ContentsVehicle DescriptionPart: 1H I G H - VO LTA G E C A B L E SElectrical energy flows between the high-voltage batterymodule and the motor through heavy-duty orange cables.In the Accord Hybrids and the 2006-2012 Civic Hybrids,high-voltage cables also deliver current to the airconditioning (AC) compressor. This allows the AC tocontinue running when the vehicle is in the Auto IdleStop mode.

Table of ContentsPart: 1Potential HazardsHonda hybrids do not present any unusual hazards. Thevehicles have performed well in standard crash tests, with nodamage to high-voltage components in front, side, orrear impacts.FLAMMABLE FLUIDSGasoline-electric hybrids have the same potential fire andexplosion hazards as conventional vehicles. (See modelspecific pages for flammable fluid capacities.)U N D E P L OYE D A I R B A G S A N D T E N S I O N E R SAll Honda hybrids have front airbags and front seat belttensioners. All except 2000-2006 Insights have side airbags infront, and side curtain airbags are standard in all Accords,2006 and later Civics, 2010 and newer Insights, and CR-Zs.These systems all use pyrotechnic devices with a deactivationtime of 3 minutes.Follow recommended procedures to avoid possibleinjury from a deploying airbag or inflator.As with other airbag-equipped vehicles, being struck by adeploying front or side airbag, or cutting into an unactivatedinflator, can result in moderate to severe injuries. Injuries canalso result from contact with a deploying side curtain airbag,or having a seat belt tensioner activate unexpectedly.To reduce the risk of injury during the deactivation period,we recommend the following: Keep out of the path of an undeployed front airbag, anddo not cut into the center of the steering wheel ordashboard where the front airbags are stored. Do not cut into the rear (C) pillar on Accords, CR-Zs, 2006and later Civics, and 2010 and newer Insights, as that iswhere side curtain inflators are stored. Be aware that extreme heat (320-356ºF; 160-180ºC) cancause unintended airbag inflation.6

Table of ContentsPotential HazardsPart: 1E L EC T R I C S H O C K P OT E N T I A LUnprotected contact with any electrically charged (“hot”or “live”) high-voltage component can cause seriousinjury or death. However, receiving an electric shockfrom a Honda hybrid is highly unlikely because ofthese facts: Contact with the battery module or other componentsinside the battery box can occur only if the box isdamaged and the contents are exposed, or the box isopened without following proper precautions. Contact with the electric motor can occur only afterone or more components are removed. The high-voltage cables can be easily identified bytheir distinctive orange color, and contact with themcan be avoided.It’s also important to understand in what situations theCurrent Flows from Battery to Motorhigh-voltage cables can potentially be “hot”:All Honda Hybrids: Whenever the ignition switch is inthe ON position and the engine is running, the high-voltageCables “Hot”battery is either supplying current to the electric motor orreceiving current generated by the electric motor.Current Flows from Motor to BatteryCables “Hot”7

Table of ContentsPart: 1Potential HazardsCurrent Flows from Battery to AC CompressorAccord and 2006-2012 Civic Hybrids: With these models,the high-voltage battery powers the air conditionercompressor as well as the electric motor. So, if the ignitionCables “Hot”switch is in the ON position, the air conditioner is on, andthe engine has been turned off by the Auto Idle Stop feature(at a stop light, for example), current will flow through theIgnition Switch is OFFcables to the air conditioner compressor.Regardless of the model, if the ignition switch is turned off,the flow of high-voltage current will stop.Cables NOT “Hot”The lesson, therefore, is: Electric current cannot flow intothe high-voltage cables when the ignition is OFF.H I G H - VO LTA G E B AT T E R Y E L EC T R O LY T ESmall quantities of a highly alkaline liquid electrolyte, whichis corrosive to human tissue, are used in the manufacture ofthe NiMH high-voltage battery cells in all Honda hybridsElectrolyte in the high-voltage battery cells is non-liquidand should not present a hazard.except the 2012 Civic Hybrid. However, in the finished cells,electrolyte is non-liquid and sealed in a sturdy case, and anyleakage would be rare. The electrolyte is also non-flammable,non-explosive, and it creates no hazardous fumes or vaporsin normal operating conditions, or in a fire.The electrolyte in the Li-Ion battery module in the 2012 CivicHybrid is flammable and will burn if the battery box isbroken open, giving off gases that can cause irritation ifinhaled. If the electrolyte simply leaks out, appropriate skinand eye protection are recommended.1 2 -VO LT B AT T E R Y E L EC T R O LY T EAny hazards from contact with the 12-volt battery electrolyteare the same as those with batteries in conventionalpassenger vehicles.8

Table of ContentsEmergency ProceduresPart: 1Based on discussions with rescue professionals,we recommend that emergency response personnelfollow standard procedures developed by their ownorganization for assessing situations and dealing withpotential hazards. Given our knowledge of Hondahybrids, we also recommend that you use the proceduresoutlined in this section.VEHICLE FIREThere are no unusual hazards if a Honda hybrid isinvolved in a fire. If the 2012 Civic Hybrid’s Li-Ion batterybox is engulfed in flames, or temperatures reach above130ºC (266ºF ) , a pressure relief valve will open andrelease pressure, so the battery should not explode.However, the contents will burn, giving off gases that canStandard procedures are recommended if a Honda hybridis involved in a fire. Responders should also be aware ofprocedures for vehicles with an Li-Ion battery box.cause irritation if inhaled. To extinguish a burningbattery, the manufacturer recommends CO2 or anabundance of water.S U B M E R G E D O R PA R T I A L LYSUBMERGED VEHICLEPull the vehicle out of the water, then use one of theprocedures described below for preventing electriccurrent from flowing through the high-voltage cables.There is no risk of electric shock from touching thecar’s body or framework—in or out of the water.Pull vehicle from water, then follow recommendedprocedures for preventing high-voltage current flow.PREVENTING CURRENT FLOW THROUGHH I G H - VO LTA G E C A B L E SBefore attempting to rescue occupants or move adamaged Honda hybrid, you should reduce the potentialfor current to flow from the electric motor or the batterymodule through the high-voltage cables.There are two recommended methods for preventingcurrent flow. These are discussed on the following pages.9
