JUMP STARTING THE VEHICLE WARNINGS
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. WARNINGS
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. Use only adequately sized cables with
insulated clamps.
Preparing Your Vehicle
Do not attempt to push-start your automatic
transmission vehicle.
Note:
Attempting to push-start a vehicle with
an automatic transmission may cause
transmission damage.

CHANGING THE 12V BATTERY
WARNINGS
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. 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. WARNINGS
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. Battery posts, terminals and related
accessories contain lead and lead
compounds. Wash hands after handling. This vehicle may be fitted with more
than one battery. Removing the battery
cables from only one battery does not
disconnect your vehicle electrical system.
Make sure you disconnect the battery cables
from all batteries when disconnecting power.
Failure to do so may cause serious personal
injury or property damage. 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:
After cleaning or replacing the battery,
make sure you reinstall the battery cover or
shield.
Note: If you add electrical accessories or
components to the vehicle, it may adversely
affect the low voltage battery performance
and durability. This may also affect the
performance of other electrical systems in
the vehicle.
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 your vehicle
’s engine is
electronically controlled by a computer, 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. 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 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. See Audio System
(page 339). Reset the power windows
bounce-back feature. See Windows and
Mirrors (page 90). Reset the radio station
presets.
See Audio System (page 339). 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, the
idle quality of your vehicle may be adversely
affected 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 may 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 battery
cables 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 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
displays 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.
