Disconnect Gryphon Before Jump Starting.

I agree that this might me a good/safe idea, but I'm also wondering if people are relying on old methods to connect the jumper vehicle. I've highlighted in red the steps that a lot of owners may do improperly. I could be totally wrong, but I know my Dad taught me the wrong way (an old Army CW4 (maintenance officer) taught me the right way back in 1987).

From the 2009 Owner's Manual:

1. Use only a 12–volt supply to start your vehicle.
2. Do not disconnect the battery of the disabled vehicle as this could damage the vehicle’s electrical system.
3. 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.
4. Check all battery terminals and remove any excessive corrosion before you attach the battery cables. Ensure that vent caps are tight and level.
5. Turn the heater fan on in both vehicles to protect from any electrical surges. Turn all other accessories off.

Connecting the jumper cables
1. Connect the positive (+) jumper cable to the positive (+) terminal of the discharged battery.
2. Connect the other end of the positive (+) cable to the positive (+)terminal of the assisting battery.
3. Connect the negative (-) cable to the negative (-) terminal of the assisting battery.

4. Make the final connection of the negative (-) cable to an exposed metal part of the stalled vehicle’s engine, away from the battery and the carburetor/fuel injection system.
Do not use fuel lines, engine rocker covers or the intake manifold as grounding points.
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.
5. Ensure that the cables are clear of fan blades, belts, moving parts of both engines, or any fuel delivery system parts.

Jump starting

1. Start the engine of the booster vehicle and run the engine at moderately increased speed.
2. Start the engine of the disabled vehicle.
3. Once the disabled vehicle has been started, run both engines for an additional three minutes before disconnecting the jumper cables.

Removing the jumper cables

Remove the jumper cables in the reverse order that they were connected.

1. Remove the jumper cable from the ground metal surface.
2. Remove the jumper cable on the negative (-) connection of the booster vehicle’s battery.

3. Remove the jumper cable from the positive (+) terminal of the booster vehicle’s battery.

4. Remove the jumper cable from the positive (+) terminal of the disabled vehicle’s battery.

After the disabled vehicle has been started and the jumper cables removed, allow it to idle for several minutes so the engine computer can relearn its idle conditions
