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.
Note: Use only a 12-volt supply to start your
vehicle.
Note: Do not disconnect the battery of the
disabled vehicle as this could damage the
vehicle electrical system.
Park the booster vehicle close to the hood
of the disabled vehicle, making sure the two
vehicles do not touch. Connecting the Jumper Cables WARNINGS
Do not attach the cables to fuel lines,
engine rocker covers, the intake
manifold or electrical components as
grounding points. Stay clear of moving parts.
To avoid reverse polarity connections, make
sure that you correctly identify the positive
(+) and negative (-) terminals on both the
disabled and booster vehicles before
connecting the cables. Do not attach the end of the positive
cable to the studs or L-shaped eyelet
located above the positive (+) terminal of
your vehicle ’s battery. High current may flow
through and cause damage to the fuses. Do not connect the end of the second
cable to the negative (-) terminal of the
battery to be jumped. A spark may cause an
explosion of the gases that surround the
battery. Note:
In the illustration, the bottom vehicle
represents the booster vehicle. 1. Connect the positive (+) jumper cable to
the positive (+) terminal of the discharged
battery.

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.
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 399). Reset the power windows
bounce-back feature. See Windows and
Mirrors (page 100).
Reset the radio station
presets. See Audio System (page 399). 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: 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.
