HYBRID VEHICLE OPERATION
This hybrid vehicle combines electric andgasoline propulsion to provide breakthroughperformance and improved efficiency.
Familiarizing yourself with these uniquecharacteristics will provide an optimal drivingexperience from your new vehicle.
Note:You may notice higher engine speedsupon start-up. This temporary condition isnormal and necessary to heat up the cabinand minimize emissions.
Starting:
When you start your vehicle, agreen ready indicator light willappear in the lower right portionof the instrument cluster and a ready to drivemessage will appear in the middle of the leftcluster screen, letting you know that yourvehicle is ready for driving.
The engine may not start because thisvehicle is equipped with silent key start. Thisfuel saving feature allows your vehicle to beready–to–drive without requiring the gasengine to be running. This indicator willremain on while your vehicle is on, whetherthe engine is running or not to indicate yourvehicle is capable of movement (using itselectric motor, engine, or both). Typically, theengine will not start unless the vehicle iscold, a climate control change is requested,or the accelerator is pressed.
Driving:
The gas engine automatically starts andstops to provide power when needed andto save fuel when not needed. Whilecoasting at low speeds, coming to a stop, orstanding, the gas engine normally shutsdown and your vehicle operates inelectric-only mode.
Conditions that may cause the engine to startup or remain running include:
•Considerable vehicle acceleration.
•Vehicle speed above 85 mph (137 km/h).However, the maximum speed forelectric-only operation may be lowerwhile driving in hot temperatures or onhilly terrain.
•Ascending a hill.
•Charge level of high voltage battery islow.
•Very high or low outside temperature (toprovide system cooling or heating).
•Engine not warm enough to providepassenger requested cabin temperature.
Stopping:
The gas engine may shut off to conserve fuelas you come to a stop. Restarting yourvehicle is not required. Simply step on theaccelerator when you are ready to drive.

During certain events (such as vehicleservicing) your low voltage 12-volt batterymay become disconnected or disabled. Oncethe battery is reconnected and after drivingthe vehicle, the engine may continue tooperate for three to five seconds after thekey is turned to off. This is a normalcondition.
Braking:
Your hybrid is equipped with standardhydraulic braking and regenerative braking.Regenerative braking is performed by yourtransmission and it captures brake energyand stores it in your high voltage battery.
Driving to Optimize Fuel Economy
Note:Having your engine running is notalways an indication of inefficiency. In somecases, it is actually more efficient thandriving in electric mode.
Your fuel economy should improvethroughout your hybrid's break-in period. Aswith any vehicle, your driving habits andaccessory usage can significantly impactyour fuel economy. For best results, keep inmind these tips:
•Keep the tires properly inflated and onlyuse the recommended size.
•Aggressive driving increases the amountof energy required to move your vehicle.In general, you can achieve better fueleconomy with mild to moderateacceleration and deceleration. Moderatebraking is particularly important since itallows you to maximize the energycaptured by the regenerative brakingsystem.
Additional Tips:
•Do not carry extra loads.
•Be mindful of adding externalaccessories that may increaseaerodynamic drag.
•Observe posted speed limits.
•Perform all scheduled maintenance.
•There is no need to wait for your engineto warm up. The vehicle is ready to driveimmediately after starting.
ECOSELECT
EcoSelect is a drive mode for non plug-invehicles designed to offer the best possiblefuel economy with tradeoffs in vehicleperformance and comfort.
To switch EcoSelect on, press theECO button.
A graphic displays on your informationdisplay when EcoSelect is on.
Your vehicle will remember the last selectedmode whenever you start your vehicle.
EcoSelect allows your vehicle to operatemore efficiently. You will notice:

HYBRID VEHICLE FREQUENTLY ASKED QUESTIONS
AnswerQuestion
The high voltage battery is electrically isolated from the rest of thevehicle when the key is off. When you switch the key on, high voltagecontactors inside the battery are closed to make the electricity avail-able to the motor and generator and enable the vehicle to drive. Theclicks are the sound of these contactors as they close and open duringstart up and shut down.
What are the series of clicks from the cargo area when I first turn thekey in the ignition?
The vehicle's computer will determine if an engine start is requiredat key-on. Silent key start will start the engine if it is necessary forcabin heating, windshield defrost, or if the outside temperature is low.
Why does the engine sometimes start at key-on?
There are several reasons the engine stays on for an extended amountof time when you first start it. One common reason is to make surethat the emissions components are warm enough to minimize tailpipeemissions. As the climate gets cooler, this engine-on time is extended.
Why does it take a long time before the engine shuts down?
The engine is required to turn on above this speed to protect thetransmission hardware.Why does my engine never shut down above 85 mph (137 km/h)

During fuel freshness mode:
•The information display will indicate fuelfreshness mode is active.
•The vehicle will only run in hybrid mode. EV Now mode will not be available.
•Most of the plug-in power will be storeduntil fuel freshness mode is completed.
Note:EV Now mode resumes when less than1.2 gal (4.5 L) of fuel remains in the fuel tank.
Note:When the fuel level is less thanone-quarter full, refueling your vehicle willend fuel freshness mode.
Note:We recommend you use a fuelstabilizer if you use less than a full tank offuel during an 18-month period.
FUEL FILLER FUNNEL LOCATION
The fuel filler funnel is under the luggagecompartment floor covering.RUNNING OUT OF FUEL
Avoid running out of fuel because thissituation may have an adverse effect onvehicle components.
If you have run out of fuel:
•To start the vehicle with a keylessignition, just start the engine. Crank timewill be longer than usual.
•Normally, adding 1 gal (3.8 L) of fuel isenough to restart the vehicle. If thevehicle is out of fuel and on a steepgrade, more than 1 gal (3.8 L) may berequired.
•The service engine soon indicator maycome on.
Refilling With a Portable Fuel Container
WARNING: Flow of fuel through a fuelpump nozzle can produce static electricity.This can cause a fire if you are filling anungrounded fuel container.
WARNING: Do not insert the nozzle ofa fuel container or an aftermarket funnel intothe fuel filler neck. This may damage the fuelsystem filler neck or its seal and cause fuelto run onto the ground.

If the service engine soon indicator remainson, have your vehicle serviced at the firstavailable opportunity. Although somemalfunctions detected by the OBD-II may nothave symptoms that are apparent, continueddriving with the service engine soon indicatoron can result in increased emissions, lowerfuel economy, reduced engine andtransmission smoothness and lead to morecostly repairs.
Readiness for Inspection andMaintenance (I/M) Testing
Some state and provincial and localgovernments may haveInspection/Maintenance (I/M) programs toinspect the emission control equipment onyour vehicle. Failure to pass this inspectioncould prevent you from getting a vehicleregistration.
If the service engine soon indicatoris on or the bulb does not work,your vehicle may need service.See On-Board Diagnostics.
Your vehicle may not pass the I/M test if theservice engine soon indicator is on or notworking properly (bulb is burned out), or ifthe OBD-II system has determined that someof the emission control systems have notbeen properly checked. In this case, thevehicle is not ready for I/M testing.
If the vehicle’s engine or transmission hasjust been serviced, or the battery hasrecently run down or been replaced, theOBD-II system may indicate that the vehicleis not ready for I/M testing. To determine ifthe vehicle is ready for I/M testing, turn theignition key to the on position for 15 secondswithout cranking the engine. If the serviceengine soon indicator blinks eight times, itmeans that the vehicle is not ready for I/Mtesting; if the service engine soon indicatorstays on solid, it means that your vehicle isready for I/M testing.
The OBD-II system checks the emissioncontrol system during normal driving. Acomplete check may take several days.
If the vehicle is not ready for I/M testing, youcan perform the following driving cycleconsisting of mixed city and highway driving:
1. 15 minutes of steady driving on anexpressway or highway followed by 20minutes of stop-and-go driving with atleast four 30-second idle periods.
2.Allow your vehicle to sit for at least eighthours with the ignition off. Then, start thevehicle and complete the above drivingcycle. The vehicle must warm up to itsnormal operating temperature. Oncestarted, do not turn off the vehicle untilthe above driving cycle is complete.
If the vehicle is still not ready for I/M testing,you need to repeat the above driving cycle.
