12–Volt Battery
The original equipment battery is maintenance-free. Do not remove the cap and do not add fluid.
Refer to the replacement number shown on the original battery label when a new 12-volt battery is needed. The vehicle has an Absorbent Glass Mat (AGM) 12-volt battery. Installation of a standard 12-volt battery will result in reduced 12-volt battery life. Some 12-volt chargers have an AGM battery setting. This setting limits the charge voltage to 14.8 volts and helps extend the battery life. If available, use the AGM setting when charging the battery.
Warning
Battery posts, terminals, and related accessories can expose you to chemicals including lead and lead compounds, which are known to the State of California to cause cancer and birth defects or other reproductive harm. Wash hands after handling.
High Voltage Battery
Only a trained service technician should inspect, test, or replace the high-voltage battery. The dealer has information on how to recycle the high-voltage battery.
Warning
Damage to the high-voltage battery or high-voltage system can create a risk of electric shock, overheating, or fire.
If the vehicle is damaged from a moderate to severe crash, flood, fire, or another event, the vehicle should be inspected as soon as possible. Until the vehicle has been inspected, store it outside at least 15 m (50 ft) from any structure or anything that can burn. Ventilate the vehicle by opening a window or a door.
Contact Customer Assistance as soon as possible to determine whether an inspection is needed.
If the vehicle is in a crash, the sensing system may shut down the high-voltage system. When this occurs, the high-voltage battery is disconnected and the vehicle will not start. The SERVICE VEHICLE SOON message in the Driver Information Center (DIC) will display. Before the vehicle can operate again, it must be serviced at your dealer.
Keep the vehicle plugged in, even when fully charged, to keep the high-voltage battery temperature ready for the next drive. This is important when outside temperatures are extremely hot or cold. Propulsion power may be reduced in extremely cold temperatures, or if the high-voltage battery is too cold. The message BATTERY TOO COLD, PLUG-IN TO WARM will display. A vehicle cover, which can reduce sun loading on the vehicle and improve high voltage battery life, is available from your dealer.
Vehicle Storage
The best way to store the vehicle for any length of time is to plug in the charge cord and leave it plugged in. The vehicle monitors and maintains the 12-volt battery daily. It is okay to leave the vehicle plugged in for extended periods of time. Once charged to full, very little energy is required to maintain the 12-volt battery and high-voltage battery.
If it is not possible to charge the vehicle with the charge cord left plugged in, be sure to fully charge the high-voltage battery before storing it. The vehicle will stop maintenance of the 12-volt battery if the high-voltage battery state of charge gets too low.
When storing the vehicle on a long-term basis:
- Keep the high voltage battery state of charge at 30%.
- Attach an AGM/VRLA compatible battery tender or trickle charger to the 12-volt battery.
- Keep the remote key more than 3 m (10 ft) away from the vehicle.
12–volt Battery
Warning
Batteries have acid that can burn you and gas that can explode. You can be badly hurt if you are not careful. Always wear eye protection. See Jump Starting – North America 8 for tips on working around a battery without getting hurt.
A trickle charger may be attached to the 12-volt battery terminals or trickle charge from the underhood remote positive (+) and negative (–) terminals. See Jump Starting -North America for the location of these terminals.
Caution
The vehicle is equipped with an AGM/VRLA 12-volt battery, which can be damaged by using the incorrect type of trickle charger. An AGM/VRLA-compatible charger must be used, with the appropriate setting selected. Follow the trickle charger manufacturer’s instructions.
With a trickle charger connected to the 12-volt battery, the vehicle will still monitor the 12-volt battery daily, but it will not use energy from the high-voltage battery for maintenance.
High Voltage Battery
After extended storage, it is possible that the vehicle may not operate. If this happens, the high-voltage battery may need to be plugged in and charged.
Park Brake and P (Park) Mechanism Check
Warning
When you are doing this check, the vehicle could begin to move. You or others could be injured and property could be damaged. Make sure there is room in front of the vehicle in case it begins to roll. Be ready to apply the regular brake at once should the vehicle begin to move.
Park on a fairly steep hill, with the vehicle facing downhill. Keeping your foot on the regular brake, set the Electric Parking Brake (EPB).
- To check the EPB’s holding ability: With the propulsion system active and the electric drive unit in N (Neutral), slowly remove foot pressure from the regular brake pedal. Do this until the vehicle is held by the EPB only.
- To check the P (Park) mechanism’s holding ability: With the propulsion system active, shift to P (Park). Then release the EPB and slowly remove foot pressure from the regular brake pedal.
