CHECKING THE COOLANT
WARNING: Do not remove thecoolant reservoir cap when the vehicleis on or the cooling system is hot. Wait10 minutes for the cooling system to cooldown. Cover the coolant reservoir capwith a thick cloth to prevent thepossibility of scalding and slowly removethe cap. Failure to follow this instructioncould result in personal injury.
WARNING: Do not put coolant inthe windshield washer reservoir. Ifsprayed on the windshield, coolant couldmake it difficult to see through thewindshield.
WARNING: Do not add coolantfurther than the MAX mark.
Note: Coolant expands when it is hot. Thelevel may extend beyond the MAX mark.
Your vehicle has a battery cooling systemand a motor electrical cooling system. SeeUnder Hood Overview (page 325). Theluggage compartment covers need to beremoved in order to access the reservoirs.See Installing and Removing theLuggage Compartment Cover (page 297).
When the electric motor is cold, check theconcentration and level of the coolant atthe intervals listed in the scheduledmaintenance information. See ScheduledMaintenance (page 410).
Maintain coolant concentration within48% to 50%, which equates to a freezepoint between -29–-35°F (-34–-37°C).Check coolant concentration using arefractometer. We do not recommend theuse of hydrometers or coolant test stripsfor measuring coolant concentration.
Adding Coolant
It is very important to use predilutedcoolant approved to the correctspecification in order to avoid plugging thesmall passageways in the electric motorcooling system. See Cooling SystemCapacity and Specification (page 366).
Do not mix different colors or types ofcoolant in your vehicle. Mixing of coolantsor using an incorrect coolant may harm theelectric motor or cooling systemcomponents and may cause damage thatthe vehicle warranty may not cover.
Note:Automotive fluids are notinterchangeable.
Note:Do not use stop leak pellets, coolingsystem sealants, or non-specified additivesas they can cause damage to the electricmotor cooling or heating systems.

Note:If prediluted coolant is not available,use the approved concentrated coolantdiluting it to 50/50 with distilled water. SeeCooling System Capacity andSpecification (page 366). Using water thathas not been deionized could contribute todeposit formation, corrosion and pluggingof the small cooling system passageways.
Note:Coolants marketed for all makes andmodels might not meet our specificationsand could cause damage to the coolingsystem. Resulting component damagecould void the vehicle warranty.
If the coolant level is at or below theminimum mark, add prediluted coolantimmediately.
To top up the coolant level do thefollowing:
1.Unscrew the cap slowly. Any pressureescapes as you unscrew the cap.
2.Add prediluted coolant approved tothe correct specification. See CoolingSystem Capacity and Specification(page 366).
3.Add enough prediluted coolant toreach the 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 coolant to bring the coolantlevel to the correct level.
If you have to add more than 1.1 qt (1 L) ofcoolant per month, have your vehiclechecked as soon as possible. Operatingyour vehicle with a low level of coolant canresult in overheating and possible electricmotor damage.
In case of emergency, you can add a largeamount of water without coolant in orderto reach a vehicle service location. In thisinstance, have qualified personnel do thefollowing as soon as possible:
1.Drain the cooling system.
2.Chemically clean the coolant system.
3.Refill with coolant.
Water alone, without coolant, can causedamage from corrosion, overheating orfreezing.
Do not use the following as a coolantsubstitute:
•Alcohol.
•Methanol.
•Brine.
•Any coolant mixed with alcohol ormethanol antifreeze.
Alcohol and other liquids can causedamage from overheating or freezing.
Do not add extra inhibitors or additives tothe coolant. These can be harmful andcompromise the corrosion protection ofthe coolant.
Recycled Coolant
We do not recommend the use of recycledcoolant, as an approved recycling processis not yet available.
Dispose of used coolant in an appropriatemanner. Follow your community'sregulations and standards for recycling anddisposing of automotive fluids.

Severe Climates
If you drive in extremely cold climates:
•It may be necessary to increase thecoolant concentration above 50%.
•A coolant concentration of 60%provides improved freeze pointprotection.
•Coolant concentrations above 60%decrease the overheat protectioncharacteristics of the coolant and maycause damage to the electric motor.
If you drive in extremely hot climates:
•You can decrease the coolantconcentration to 40%.
•A coolant concentration of 40%provides improved overheat protection.
•Coolant concentrations below 40%decrease the overheat and corrosionprotection characteristics of thecoolant and may cause damage to theelectric motor.
Coolant Change
Change the coolant at specific mileageintervals listed in the scheduledmaintenance information. Add predilutedcoolant approved to the correctspecification. See Cooling SystemCapacity and Specification (page 366).
12V BATTERY
CHANGING THE 12V BATTERY
If the 12 volt battery needs servicing, seeyour authorized dealer.
CHARGING THE 12V BATTERY
Your vehicle has a high voltage to lowvoltage energy transfer feature that keepsthe 12 volt battery charged by the highvoltage battery. If the 12 volt battery levelis low, the high voltage battery transfersenergy to the 12 volt battery when thevehicle is off.

PREPARING YOUR VEHICLE
FOR STORAGE
If you plan on storing your vehicle for 30days or more, read the followingmaintenance recommendations to makesure your vehicle stays in good operatingcondition.
We engineer and test all vehicles and theircomponents for reliable, regular driving.Under various conditions, long-termstorage may lead to degradedperformance or failure unless you usespecific precautions to preserve vehiclecomponents.
General
•Store all vehicles in a dry, ventilatedplace.
•Protect from sunlight, if possible.
•If vehicles are stored outside, theyrequire regular maintenance to protectagainst rust and damage.
Body
•Wash your vehicle thoroughly toremove dirt, grease, oil, tar or mud fromexterior surfaces, rear-wheel housingand the underside of front fenders.
•Periodically wash your vehicle if it isstored in exposed locations.
•Touch-up exposed or primed metal toprevent rust.
•Cover chrome and stainless steel partswith a thick coat of auto wax to preventdiscoloration. Re-wax as necessarywhen you wash your vehicle.
•Lubricate all hood, door and luggagecompartment hinges and latches witha light grade oil.
•Cover interior trim to prevent fading.
•Keep all rubber parts free from oil andsolvents.
Cooling system
•Protect against freezing temperatures.
•When removing your vehicle fromstorage, check coolant fluid level.Confirm that there are no coolingsystem leaks and that fluid is at therecommended level.
Battery Systems
We recommend the following actions foryour vehicle:
•When storing your vehicle for greaterthan 30 days the state of chargeshould be approximately 50%.Additionally, we recommenddisconnecting the 12v battery whichwill reduce system loads on the HVbattery.
Note:Make sure the vehicle has beenswitched off and doors closed for at leastfive minutes before disconnecting the 12 voltbattery.
