Note: After cleaning or replacing the
battery, make sure you reinstall the battery
vent tube, battery cover or shield.
For longer, trouble-free operation, keep the
top of the battery clean and dry.
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 a computer electronically controls
your vehicle's engine, power from the
battery maintains some control conditions.
When you disconnect or have a new
battery installed, the engine must relearn
its idle and fuel trim strategy for optimum
driveability and performance. Flexible fuel
vehicles (FFV) must also relearn the
ethanol content of the fuel for optimum
driveability and performance.
To restore the settings, do the following:
1. Apply the parking brake.
2. Shift into park (P) or neutral (N).
3. Switch off all the accessories.
4. Press the brake pedal and start your
vehicle.
5. Run the engine until it reaches normal
operating temperature. While the
engine is warming up, complete the
following: Reset the clock. Reset the
power windows bounce-back feature.
See Windows and Mirrors (page 92).
Reset the radio station presets. See
Audio System (page 409).
6. Allow the engine to idle for at least one
minute.
7. 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, you
could adversely affect the idle quality of
your vehicle until the engine computer
eventually relearns the idle trim and fuel
trim strategy.
Note: For flexible fuel vehicles, if you are
operating on E85, you could experience poor
starts or an inability to start the engine and
driveability problems until the fuel trim and
ethanol content have been relearned.
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
negative battery cable to maintain battery
charge for quick starting.
Battery Management System (If
Equipped)
The battery management system monitors
battery conditions and takes actions to
extend battery life. If the system detects
excessive battery drain, it temporarily
disables some electrical systems to
protect the battery.
Systems included are:
• Heated rear window.
• Heated seats.
• Climate control.
• Heated steering wheel.
• Audio unit.
• Navigation system.
A message could appear in the information
display to alert you that battery protection
actions are active. These messages are
only for notification that an action is taking
place, and not intended to indicate an
electrical problem or that the battery
requires replacement.
