GENERAL INFORMATION
WARNING: Extended idling at highengine speeds can produce very hightemperatures in the engine and exhaustsystem, creating the risk of fire or otherdamage.
WARNING: Do not park, idle ordrive your vehicle on dry grass or otherdry ground cover. The emission systemheats up the engine compartment andexhaust system, creating the risk of fire.
WARNING: Do not start the enginein a closed garage or in other enclosedareas. Exhaust fumes are toxic. Alwaysopen the garage door before you startthe engine. Failure to follow thisinstruction could result in personal injuryor death.
WARNING: Exhaust leaks mayresult in entry of harmful and potentiallylethal fumes into the passengercompartment. If you smell exhaustfumes inside your vehicle, have yourvehicle inspected immediately. Do notdrive if you smell exhaust fumes.
The powertrain control system meets allCanadian interference-causing equipmentstandard requirements regulating theimpulse electrical field or radio noise.
Note:If you use your vehicle regularly abovethe altitude of 7,500 ft (2,286 m) and underthe temperature of -4.0°F (-20°C), it isrecommended to use the alternative engineoil. See Capacities and Specifications(page 378).
If you disconnect the battery, your vehiclemay exhibit some unusual drivingcharacteristics for approximately 6 mi(10 km) after you reconnect it. This isbecause the engine management systemmust realign itself with the engine. You candisregard any unusual drivingcharacteristics during this period.
When you start the engine, avoid pressingthe accelerator pedal before and duringoperation. Only use the accelerator pedalwhen you have difficulty starting theengine.
IGNITION SWITCH
0 (off) - The ignition is off.
Note: When you switch the ignition off andleave your vehicle, do not leave your key inthe ignition. This could cause your vehiclebattery to lose charge.
I (accessory) - Allows the electricalaccessories, such as the radio, to operatewhile the engine is not running.
Note: Do not leave the ignition key in thisposition for too long.This could cause yourvehicle battery to lose charge.
II (on) - All electrical circuits areoperational and the warning lamps andindicators illuminate.
III (start) - Cranks the engine.

Automatic Engine Shutdown
For vehicles with a keyless ignition, thisfeature shuts down the engine if it hasbeen idling for an extended period. Theignition also turns off in order to savebattery power. Before your vehicle shutsdown, a message appears in theinformation display showing a timercounting down from 30 seconds. If you donot intervene within 30 seconds, yourvehicle shuts down. Another messageappears in the information display toinform you that your vehicle has shut downto save fuel. Start your vehicle as younormally do.
Automatic Engine Shutdown Override
You can stop the shutdown, or reset thetimer, at any point before the 30-secondcountdown has expired by doing any of thefollowing:
•You can reset the timer by interactingwith your vehicle, for example pressingthe brake or accelerator pedal.
•You can temporarily switch off theshutdown feature any time the ignitionis on. Use the vehicle settings on yourtouchscreen to switch the 30min MaxIdle on or off. The feature only remainsoff for the current ignition cycle.
•During the 30-second countdown, thesystem prompts you to press OK orRESET to temporarily switch thefeature off for the current ignition cycleonly.
Note:You cannot permanently switch offthe automatic shutdown feature. When youtemporarily switch it off, it turns on at thenext ignition cycle.
Stopping the Engine When YourVehicle is Stationary

HYBRID VEHICLE OPERATION
- HYBRID ELECTRIC VEHICLE
(HEV)
This hybrid vehicle combines electric andgasoline propulsion to providebreakthrough performance and improvedefficiency. Familiarizing yourself with theseunique characteristics provides an optimaldriving experience from your vehicle.
Starting
When you start your vehicle, agreen READY indicator lightappears in the instrument clusterletting you know that your vehicle is readyfor driving.
The engine may not start because yourvehicle has a silent key start feature. Thisfuel saving feature allows your vehicle tobe ready to drive without requiring the gasengine to be running. The indicator remainson when your vehicle is on, whether theengine is running or not, to indicate yourvehicle is capable of movement using theelectric motor, gas engine or both.Typically, the engine does not start unlessthe vehicle is cold, a climate controlchange is requested or you press theaccelerator pedal.
Driving
The gas engine automatically starts andstops to provide power when needed andto save fuel when not needed. Whencoasting at low speeds, coming to a stop,or standing, the gas engine normally shutsdown and your vehicle operates inelectric-only mode.
Conditions that may cause the engine tostart up or remain running include:
•Considerable vehicle acceleration.
•Climbing a hill.
•Charge level of high voltage battery islow.
•High or low outside temperatures inorder to provide system heating orcooling.
•Engine not warm enough to providepassenger requested cabintemperature.
•Towing a trailer.
•Selectable drive modes: Certainselectable drive modes may cause theengine to run. See What Is Drive ModeControl (page 273).
•Live in Drive: Use of the paddle shifterswhile in drive (D) may cause the engineto run. See Automatic Transmission(page 197).
Stopping
The gas engine may shut off to conservefuel as you come to a stop. Restarting yourvehicle is not required. Simply step on theaccelerator when you are ready to drive.
Transmission Operation
The engine and electric motor togetherpropel the vehicle through the automatictransmission. This is normal hybridoperating and helps deliver fuel efficiencyand performance.
Battery
Your hybrid is equipped with a high voltagebattery. A cool battery maintains batterylife and provides the best possibleperformance. The high voltage battery iscooled by the vehicle's air conditioningsystem. When the air conditioning systemis on, you may notice a slight increase inair temperature coming from the climatecontrol vents while the battery is cooling.You may also notice cool air flowing fromthe vents when the air conditioning orblower is off.

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?
