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.
