Engage
Engage provides separate gauges for enginepower and high voltage battery power inkilowatts (kW). The engine power gauge fillis white and the high voltage battery powergauge fill is blue. You can also see aninstantaneous fuel economy gauge. Whenyour vehicle is operating on battery poweronly, you will see EV displayed and thegauges will appear in blue.
Note:Hold OK to reset average fueleconomy.
Empower
Empower provides a power demand gaugein kilowatts (kW) which includes an engineon or off threshold.
•When your vehicle is operating withbattery power only (below the threshold),you will see EV displayed and the gaugefill is blue.
•When your vehicle is operating with boththe engine and the high voltage batteryproviding power the gauge fill is white.
•When power demand surpasses theamber indicator, this level of demand andassociated fuel economy displays inamber.
•When the engine is on, reducing powerdemand to less than the threshold willallow the engine to turn off.
You can also see an instantaneous fueleconomy gauge.
Note:Hold OK to reset average fueleconomy.

•You must select content in both columnsbefore you can save your new MyView.
Unique content available in MyView:
•Accessory Power— Indicates electricalpower demands from your vehicle’saccessory systems. Accessories usepower but do not contribute to propellingyour vehicle. The gauge separatelydisplays power demand in kilowatts (kW)for climate and other accessories.Climate includes the power being usedby high voltage climate controlcomponents such as the electric A/Ccompressor. Other includes all powerbeing used by the low voltageaccessories (cabin fans, headlights andheated seats).
•Coolant Temp – Indicates engine coolanttemperature. At normal operatingtemperature, the level indicator will bewhite and will be in the normal range(between H and C). If the engine coolanttemperature exceeds the normal range,the level indicator will change to red toindicate that the engine is overheating.Stop your vehicle as soon as safelypossible, turn your vehicle off and let theengine cool.

WARNINGS
Do not use your heater withungrounded electrical systems ortwo-pronged adapters. There is a risk ofelectrical shock.
Do not fully close the hood, or allow itto drop under its own weight whenusing the engine block heater. This coulddamage the power cable and may cause anelectrical short resulting in fire, injury andproperty damage.
Note:The heater is most effective whenoutdoor temperatures are below 0°F (-18°C).
The heater acts as a starting aid by warmingthe engine coolant. This allows the climatecontrol system to respond quickly. Theequipment includes a heater element(installed in the engine block) and a wireharness. You can connect the system to agrounded 120-volt AC electrical source.
We recommend that you do the following fora safe and correct operation:
•Use a 16-gauge outdoor extension cordthat is product certified by Underwriter’sLaboratory (UL) or Canadian StandardsAssociation (CSA). This extension cordmust be suitable for use outdoors, in coldtemperatures, and be clearly markedSuitable for Use with OutdoorAppliances. Do not use an indoorextension cord outdoors. This couldresult in an electric shock or become afire hazard.
•Use as short an extension cord aspossible.
•Do not use multiple extension cords.
•Make sure that when in operation, theextension cord plug and heater cord plugconnections are free and clear of water.This could cause an electric shock or fire.
•Make sure your vehicle is parked in aclean area, clear of combustibles.
•Make sure the heater, heater cord andextension cord are firmly connected.
•Check for heat anywhere in the electricalhookup once the system has beenoperating for approximately 30 minutes.
•Make sure the system is unplugged andproperly stowed before starting anddriving your vehicle. Make sure theprotective cover seals the prongs of theblock heater cord plug when not in use.
•Make sure the heater system is checkedfor proper operation before winter.
Using the Engine Block Heater
Make sure the receptacle terminals are cleanand dry prior to use. Clean them with a drycloth if necessary.
The heater uses 0.4 to 1.0 kilowatt-hours ofenergy per hour of use. The system does nothave a thermostat. It achieves maximumtemperature after approximately three hoursof operation. Using the heater longer thanthree hours does not improve systemperformance and unnecessarily useselectricity.

Starting and Stopping the Engine

AnswerQuestion
In order to make sure that the climate control system can begin heatingthe cabin or defrosting the windshield as soon as a driver requestsit, the engine coolant temperature has to be kept sufficiently hot.Keeping the engine on is required to maintain the correct coolanttemperature.
Why does my engine stay on when it is extremely cold outside?
Your vehicle's engine and transmission are designed to deliver thepower you need at the most efficient engine speed. This may behigher than expected during heavy accelerations, and may fluctuatewhen driving at a steady speed. These are characteristics of theAtkinson engine cycle and the transmission technology that helpmaximize your hybrid's fuel economy.
Why does my engine rev up so high sometimes when I accelerate?
The fan noise comes from a fan located next to the high voltagebattery pack. This fan turns on when the battery requires cooling air.The fan speed, and associated noise level, will change according tothe amount of cooling required to maintain good performance. Main-taining the battery temperature at optimal conditions also prolongsthe useful life of the battery and helps to achieve better fuel economy.
What is the fan noise I hear from the rear of my hybrid?
Change the engine oil every 10,000 mi (16,000 km) or once per yearunder normal operating conditions.What is the engine oil change service interval?
Your hybrid vehicle can use E15 (15% ethanol, 85% gasoline) fuel, butyou may notice slightly reduced fuel economy because ethanolcontains less energy per gallon than gasoline. Your hybrid vehicle isnot designed to use E85 (85% ethanol).
Can I put E15 or E85 in my vehicle, and how will it affect my fueleconomy?
