When the battery is disconnected or a new battery is installed, the
automatic transmission must relearn its shift strategy. As a result, the
transmission may exhibit a combination of firm and soft shifts. This
operation is considered normal and will not affect function or durability
of the transmission. Over time, the adaptive learning process will fully
update transmission operation.
Preparing Your Vehicle
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's electrical system.
1. Park the booster vehicle close to the hood of the disabled vehicle
making sure the two vehicles do not touch. Set the parking brake on
both vehicles and stay clear of the engine cooling fan and other moving
parts.
2. Check all battery terminals. Remove the positive terminal cover
(if equipped) and any excessive corrosion before you attach the battery
cables. Ensure that vent caps are tight and level.
3. Turn the heater fan on in both vehicles to protect from any electrical
surges. Turn all other accessories off.
Connecting the Jumper Cables
WARNING: 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: Do not attach the negative (-) cable to fuel lines, engine rocker
covers, the intake manifold or electrical components as grounding points.
