•Park your vehicle in a clean area, clearof combustible materials.
•Firmly connect the engine block heatercord and the extension cord.
•Check the extension cord for heatanywhere when the system has beenoperating for approximately 30 minutes.
•Unplug and properly stow the systembefore starting and driving your vehicle.The protective cover seals the terminalsof the engine block heater cord plugwhen not in use.
•Check the engine block heater systemfor proper operation before winter.
HOW DOES THE ENGINE BLOCKHEATER WORK
The engine block heater warms the enginecoolant. This allows the climate controlsystem to quickly respond. The equipmentincludes a heater element installed in theengine block and a wire harness. You canconnect the system to a grounded 110 voltAC electrical source.
Note:The engine block heater is mosteffective when outdoor temperatures arebelow 0°F (-18°C). We recommend the useof engine block heater to improve enginecold start performance.
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 engine block heaterlonger than three hours does not improvesystem performance and unnecessarily useselectricity.
STOPPING THE ENGINE
STOPPING THE ENGINE WHEN YOURVEHICLE IS STATIONARY
1.Shift into park (P).
2.Apply the parking brake.
3.Wait until the engine reaches idle speed.
4.Press the push button ignition switch.
STOPPING THE ENGINE WHEN YOURVEHICLE IS MOVING
WARNING: Switching off the enginewhen your vehicle is still moving results ina significant decrease in brakingassistance.

In order to make sure that the climatecontrol system can begin heating thecabin or defrosting the windshield assoon as a driver requests it, the enginecoolant temperature has to be keptsufficiently hot. Keeping the engine onis required to maintain the correctcoolant temperature.
PLUG-IN HYBRID ELECTRIC VEHICLE
INFORMATION
WHAT IS A PLUG-IN HYBRID ELECTRICVEHICLE
A plug-in hybrid electric vehicle combines agasoline engine with an electric motor andrechargeable high voltage battery allowingyou to use only electricity to power yourvehicle.
HOW DOES A PLUG-IN HYBRIDELECTRIC VEHICLE WORK
Charging your vehicle adds electrical energythat propels the vehicle, providing extendedelectric-only driving range. System conditionscould require the engine to operate whileelectric-only range is still available. When theelectric range reaches zero, the powertrainsystem operates as a hybrid electric vehicle.See How Does a Hybrid Electric VehicleWork (page 213).
PLUG-IN HYBRID ELECTRIC VEHICLEDRIVING CHARACTERISTICS
Your plug-in hybrid vehicle shares the drivingcharacteristics of hybrid electric vehicles withthe addition of extended electric- only drivingrange and unique selectable drive modes.See Hybrid Electric Vehicle DrivingCharacteristics (page 213).
The system maximizes the use ofelectric-only operation in normal drive mode.System conditions could require the engineto operate, however, the system uses theavailable electric range whenever possible.
In Pure EV drive mode, your vehicle typicallyuses only electric power. The engineoperates to provide extra power when youfully press the accelerator pedal. Systemconditions may also require the engine tooperate.
Preserve EV drive mode saves the electricrange for later use. If you select this modeand the battery is at full or near full charge,it uses some electric-only range to dischargethe battery. This allows the regenerativebraking system to fully operate. If batterycharge is low when this mode is selected theengine charges the high voltage battery toprovide some electric range for later.
Other drive modes use electric power asnecessary to deliver the selected drive modeexperience. See What Is Drive ModeControl (page 338).
PLUG-IN HYBRID ELECTRIC VEHICLEINDICATORS
When you start your vehicle, agreen ready indicator light appearsin the instrument cluster letting youknow that your vehicle is ready for driving.

maintain high-speed operation, and maycompletely shut down without warning,potentially losing engine power, powersteering assist, and power brake assist,which may increase the possibility of acrash resulting in serious injury.
WARNING: Do not remove thecoolant reservoir cap when the engine ison or the cooling system is hot. Wait 10minutes for the cooling system to cooldown. Cover the coolant reservoir cap witha thick cloth to prevent the possibility ofscalding and slowly remove the cap.Failure to follow this instruction could resultin personal injury.
Continued operation increases the enginetemperature, causing the engine tocompletely shut down. Your steering andbraking effort increases in this situation.
When the engine temperature cools, you canre-start the engine. Have your vehiclechecked as soon as possible to minimizeengine damage.
Your vehicle has limited engine power whenin the fail-safe mode, drive your vehicle withcaution. Your vehicle does not maintainhigh-speed operation and the engine mayoperate poorly.
Remember that the engine is capable ofautomatically shutting down to preventengine damage. In this situation:
1.Pull off the road as soon as safelypossible and switch the engine off.
2.If you are a member of a roadsideassistance program, we recommend thatyou contact your roadside assistanceservice provider.
3.If this is not possible, wait for a shortperiod of time for the engine to cool.
4.Check the coolant level. If the coolantlevel is at or below the minimum mark,add prediluted coolant immediately.
5.When the engine temperature cools, youcan re-start the engine. Have your vehiclechecked as soon as possible to minimizeengine damage.
Note:Driving your vehicle without repairincreases the chance of engine damage.

COOLANT
CHECKING THE COOLANT LEVEL
WARNING: Do not remove thecoolant reservoir cap when the engine ison or the cooling system is hot. Wait 10minutes for the cooling system to cooldown. Cover the coolant reservoir cap witha thick cloth to prevent the possibility ofscalding and slowly remove the cap.Failure to follow this instruction could resultin personal injury.
WARNING: To reduce the risk ofpersonal injury, make sure the engine iscool before unscrewing the coolantpressure relief cap. The cooling system isunder pressure. Steam and hot liquid cancome out forcefully when you loosen thecap slightly.
When the engine is cold, check theconcentration and level of the coolant at theintervals listed in the scheduled maintenanceinformation. See Scheduled Maintenance(page 563).
Note:Make sure that the coolant level isbetween the MIN and the MAX marks onthe coolant reservoir.
Note: Coolant expands when it is hot. Thelevel may extend beyond the MAX mark. This is normal.

Maintain coolant concentration within 48%to 50%, which equates to a freeze pointbetween -29°F (-34°C) and -35°F (-37°C).Coolant concentration should be checkedusing a refractometer. We do not recommendthe use of hydrometers or coolant test stripsfor measuring coolant concentration.
ADDING COOLANT
WARNING: Do not add coolant whenthe vehicle is on or the cooling system ishot. Failure to follow this instruction couldresult in personal injury.
WARNING: Do not remove thecoolant reservoir cap when the engine ison or the cooling system is hot. Wait 10minutes for the cooling system to cooldown. Cover the coolant reservoir cap witha thick cloth to prevent the possibility ofscalding and slowly remove the cap.Failure to follow this instruction could resultin personal injury.
WARNING: Do not allow the fluid totouch your skin or eyes. If this happens,rinse the affected areas immediately withplenty of water and contact your physician.
WARNING: Do not put coolant in thewindshield washer reservoir. If sprayed onthe windshield, coolant could make itdifficult to see through the windshield.
WARNING: Do not add coolantfurther than the MAX mark.
Note: Do not use stop leak pellets, coolingsystem sealants, or non-specified additivesas they can cause damage to the enginecooling or heating systems. Resultingcomponent damage may not be covered bythe vehicle Warranty.
Note:Automotive fluids are notinterchangeable.
It is very important to use prediluted coolantapproved to the correct specification in orderto avoid plugging the small passageways inthe engine cooling system. See Capacitiesand Specifications (page 495). Do not mixdifferent colors or types of coolant in yourvehicle. Mixing of engine coolants or usingan incorrect coolant may harm the engine orcooling system components and may not becovered by the vehicle Warranty.
Note:If prediluted coolant is not available,use the approved concentrated coolantdiluting it to 50/50 with deionised or distilledwater. See Capacities and Specifications(page 495). Using water that has not beendeionised may contribute to depositformation, corrosion and plugging of thesmall cooling system passageways.
Note: Coolants marketed for all makes andmodels may not be approved to ourspecifications and may cause damage tothe cooling system. Resulting componentdamage may not be covered by the vehicleWarranty.

If the coolant level is at or below theminimum mark, add prediluted coolantimmediately.
To top up the coolant level do the following:
1.Unscrew the cap slowly. Any pressureescapes as you unscrew the cap.
2.Add prediluted coolant approved to thecorrect specification. See Capacities andSpecifications (page 495).
3.Add enough prediluted coolant to reachthe correct level.
4.Replace the coolant reservoir cap. Turnthe cap clockwise until it contacts thehard stop.
5.Check the coolant level in the coolantreservoir the next few times you driveyour vehicle. If necessary, add enoughprediluted engine coolant to bring thecoolant level to the correct level.
If you have to add more than 1.1 qt (1 L) ofengine coolant per month, have your vehiclechecked as soon as possible. Operating anengine with a low level of coolant can resultin engine overheating and possible enginedamage.
In case of emergency, you can add a largeamount of water without engine coolant inorder to reach a vehicle service location.
Water alone, without engine coolant, cancause engine damage from corrosion,overheating or freezing.
Do not use the following as a coolantsubstitute:
•Alcohol.
•Methanol.
•Brine.
•Any coolant mixed with alcohol ormethanol antifreeze.
Alcohol and other liquids can cause enginedamage from overheating or freezing.
Do not add extra inhibitors or additives tothe coolant. These can be harmful andcompromise the corrosion protection of thecoolant.
CHANGING THE COOLANT
For coolant change, see your authorizeddealer.
Changing the coolant is necessary at specificmileage intervals listed in the scheduledmaintenance information.
MANAGING THE COOLANTTEMPERATURE
If you tow a trailer with your vehicle, theengine may temporarily reach a highertemperature during severe operatingconditions, for example ascending a long orsteep grade in high ambient temperatures.
At this time, you may notice the coolanttemperature gauge moves toward the redzone and a message may appear in theinformation display.
WARNING: To reduce the risk ofcrash and injury, be prepared that thevehicle speed may reduce and the vehiclemay not be able to accelerate with fullpower until the coolant temperaturereduces.

WARNING: If you continue to driveyour vehicle when the engine isoverheating, the engine could stop withoutwarning. Failure to follow this instructioncould result in the loss of control of yourvehicle.
You may notice a reduction in vehicle speedcaused by reduced engine power in orderto manage the engine coolant temperature. Your vehicle may enter this mode if certainhigh-temperature and high-load conditionstake place. The amount of speed reductiondepends on vehicle loading, grade andoutside temperature. If this occurs, there isno need to stop your vehicle. You cancontinue to drive. See Fail-Safe Cooling(page 407).
The air conditioning may automatically turnon and off during severe operatingconditions to protect the engine fromoverheating. When the coolant temperaturedecreases to the normal operatingtemperature, the air conditioning turns on.
If the coolant temperature gauge moves fullyinto the red zone, or if the coolanttemperature warning or service engine soonmessages appear in your information display,do the following:
1.Stop your vehicle as soon as it is safe todo so. Fully apply the parking brake, shiftinto park (P) or neutral (N).
2.Leave the engine running until thecoolant temperature gauge needlereturns to the normal position. If thetemperature does not drop after severalminutes, follow the remaining steps.
3.Switch the engine off and wait for it tocool. Check the coolant level.
4.If the coolant level is at or below theminimum mark, add prediluted coolantimmediately.
5.If the coolant level is normal, restart theengine and continue.
