Removal and Installation

WARNING: This page is about a different car, the 2010 Mercury Mariner and 2010 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: Batteries contain sulfuric acid and produce explosive gases. Work in a well-ventilated area. Do not allow the battery to come in contact with flames, sparks or burning substances. Avoid contact with skin, eyes or clothing. Shield 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, then get prompt medical attention. If acid is swallowed, call a physician immediately. Failure to follow these instructions may result in serious personal injury.
WARNING: Always lift a plastic-cased battery with a battery carrier or with hands on opposite corners. Excessive pressure on the battery end walls may cause acid to flow through the vent caps, resulting in personal injury and/or damage to the vehicle or battery.
NOTE: Because the engine is electronically controlled by the PCM, some control conditions are maintained by power from the battery. When the battery is disconnected or a new battery is installed, the engine must relearn its idle and fuel trim strategy for optimum driveability and performance. Allow the engine to idle for one minute. The relearning process automatically completes as the vehicle is driven. The vehicle may need to be driven 16 km (10 mi). If the engine is not allowed to relearn its idle trim, the idle quality may be adversely affected until the idle trim is eventually relearned. Additionally, to account for customer driving habits and conditions, the automatic transmission must relearn its adaptive strategy. Optimal shifting resumes within a few hundred kilometers (miles) of operation. The clock and the preset radio stations must be reset once the battery is connected.
  1. Disconnect the battery. For additional information, refer to BATTERY DISCONNECT .
  2. Remove the Air Cleaner (ACL) assembly. For additional information, refer to AIR CLEANER .
  3. Remove the battery wedge clamp and bolt.
    • To install, tighten to 9 Nm (80 lb-in).
  4. Remove the battery.
