For longer, trouble-free operation, keep the
top of the battery clean and dry and the
battery cables tightly fastened to the
battery terminals. If any corrosion is
present 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.
We recommend that you disconnect the
negative battery cable terminal from the
battery if you plan to store your vehicle for
an extended period.
Note:
If you only disconnect the negative
battery cable terminal, make sure it is
isolated or placed away from the battery
terminal to avoid unintended connection or
arcing.
If you replace the battery make sure it
matches the electrical requirements of
your vehicle.
If you disconnect or replace the battery
and your vehicle has an automatic
transmission, it must relearn its adaptive
strategy. Because of this, the transmission
may shift firmly when first driven. This is
normal operation while the transmission
fully updates its operation to optimum
shift feel.
Battery Sensor Reset
When you install a new battery, reset the
battery sensor by doing the following:
1. Switch the ignition on, and leave the engine off.
Note: Complete Steps 2 and 3 within 10
seconds.
2. Flash the high beam headlamps five times, ending with the high beams off.
3. Press and release the brake pedal three
times. The battery warning lamp flashes three
times to confirm that the reset is
successful.
Battery Management System (If
Equipped)
The system monitors battery conditions
and takes actions to extend battery life. If
excessive battery drain is detected, the
system 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 may appear in the information
display to alert you that battery protection
actions are active. This message is only for
notification that an action is taking place,
and not intended to indicate an electrical
problem or that the battery requires
replacement.
After battery replacement, or in some
cases after charging the battery with an
external charger, the battery management
system requires eight hours of vehicle sleep
time to relearn the battery state of charge.
During this time, your vehicle must remain
fully locked with the ignition switched off.
Note: Prior to relearning the battery state
of charge, the battery management system
may temporarily disable some electrical
systems.
