Changing the 12V Battery
WARNING:
Batteries normally produce explosive gases which can cause personal injury. Therefore, do not allow flames, sparks or lighted substances to come near the battery. When working near the battery, always shield your face and protect your eyes. Always provide correct ventilation.
WARNING:
When lifting a plastic-cased battery, excessive pressure on the end walls could cause acid to flow through the vent caps, resulting in personal injury and damage to the vehicle or battery. Lift the battery with a battery carrier or with your hands on opposite corners.
WARNING:
Keep batteries out of reach of children. Batteries contain sulfuric acid. Avoid contact with skin, eyes or clothing. Shield your eyes when working near the battery to protect against possible splashing of acid solution. In case of acid contact with skin or eyes, flush immediately with water for a minimum of 15 minutes and get prompt medical attention. If acid is swallowed, call a physician immediately.
WARNING:
Battery posts, terminals and related accessories contain lead and lead compounds. Wash hands after handling.
WARNING:
For vehicles with Auto-Start-Stop the battery requirement is different. You must replace the battery with one of exactly the same specification. |
Your vehicle is fitted with a Motorcraft maintenance-free battery which normally does not require additional water.
When a battery replacement is required, you must use a recommended replacement battery that matches the electrical requirements of the vehicle.
Note:
If your vehicle has a battery cover, after cleaning or replacing the battery, make sure you reinstall it.
Note:
See an authorized dealer for battery access, testing, or replacement.
To make sure the battery management system works correctly, do not connect an electrical device ground connection directly to the battery negative post. This can cause inaccurate measurements of the battery condition and potential incorrect system operation.
Note:
If you add electrical accessories or components to the vehicle, it may adversely affect battery performance and durability. This may also affect the performance of other electrical systems in the vehicle.
If you see any corrosion on the battery or terminals, remove the cables from the terminals and clean with a wire brush. You can neutralize the acid with a solution of baking soda and water.
Because your vehicle’s engine is electronically-controlled by a computer, some engine control settings are maintained by power from the battery. Some engine computer settings, like the idle trim and fuel trim strategy, optimize the driveability and performance of the engine. The clock and radio station presets are also maintained in memory by power from the low-voltage battery. These settings are erased when a technician disconnects and connects the low-voltage battery.
To restore the settings, do the following:
Note:
Until you switch the ignition to the on position, you will receive a message in your information display stating that your vehicle is not in park.
- Apply the parking brake.
- Shift into park (P) or neutral (N).
- Switch off all accessories.
- Press the brake pedal and start your vehicle.
- Run the engine until it reaches normal operating temperature. While the engine is warming up, complete the following: Reset the clock. See
Audio Unit.
Reset the power windows bounce-back feature.
See Power Windows. Reset the radio station presets.
See Audio Unit.
- Allow the engine to idle for at least one minute.
- Drive the vehicle at least 10 mi (16 km) to completely relearn the idle trim and fuel trim strategy.
Note:
If you do not allow the engine to relearn the idle and fuel trim strategy, the idle quality of your vehicle may be adversely affected until the engine computer eventually relearns the idle trim and fuel trim strategy.
Note:
Certain features may not operate if the battery monitor system is not reset with a scan tool following a jump start or battery replacement. Normal electrical accessory operation should resume after your vehicle is left undisturbed for 8 hours.
Make sure that you dispose of old batteries in an environmentally friendly way. Seek advice from your local authority about recycling old batteries.
If storing your vehicle for more than 30 days without recharging the battery, we recommend that you disconnect the battery cables to maintain battery charge for quick starting.
