JUMP STARTING
WARNING: review all safety precautions and warnings in the battery system section of the service manual. (Refer to 08 - Electrical/8F - Engine Systems/Battery System/BATTERY - Standard Procedure)
Do not jump start a frozen battery, personal injury can result.
If equipped, do not jump start when maintenance free battery indicator dot is yellow or bright color.
Do not jump start a vehicle when the battery fluid is below the top of lead plates.
Do not allow jumper cable clamps to touch each other when connected to a booster source.
Do not use open flame near battery.
Remove metallic jewelry worn on hands or wrists to avoid injury by accidental arcing of battery current.
When using a high output boosting device, do not allow battery voltage to exceed 16 volts. Refer to instructions provided with device being used.
Failure to follow these instructions may result in personal injury.
CAUTION: When using another vehicle as a booster, do not allow vehicles to touch. Electrical systems can be damaged on either vehicle.
TO JUMP START A DISABLED VEHICLE:
1. Raise hood on disabled vehicle and visually inspect engine compartment for:
Battery cable clamp condition, clean if necessary.
Frozen battery.
Yellow or bright color test indicator, if equipped.
Low battery fluid level.
Generator drive belt condition and tension.
Fuel fumes or leakage, correct if necessary.
CAUTION: If the cause of starting problem on disabled vehicle is severe, damage to booster vehicle charging system can result.
2. When using another vehicle as a booster source, park the booster vehicle within cable reach. Turn off all accessories, set the parking brake, place the automatic transmission in PARK or the manual transmission in NEUTRAL and turn the ignition OFF.
3. On disabled vehicle, place gear selector in park or neutral and set park brake. Turn off all accessories.
4. Connect jumper cables to booster battery. RED clamp to positive terminal (+). BLACK clamp to negative terminal (-). DO NOT allow clamps at opposite end of cables to touch, electrical arc will result. Review all warnings in this procedure.
5. On disabled vehicle, connect RED jumper cable clamp to positive (+) terminal. Connect BLACK jumper cable clamp to engine ground as close to the ground cable attaching point as possible.
6. Start the engine in the vehicle which has the booster battery, let the engine idle a few minutes, then start the engine in the vehicle with the discharged battery.
CAUTION: Do not crank starter motor on disabled vehicle for more than 15 seconds, starter will overheat and could fail.
7. Allow battery in disabled vehicle to charge to at least 12.4 volts (75% charge) before attempting to start engine. If engine does not start within 15 seconds, stop cranking engine and allow starter to cool (15 min.), before cranking again.
DISCONNECT CABLE CLAMPS AS FOLLOWS:
Disconnect BLACK cable clamp from engine ground on disabled vehicle.
When using a Booster vehicle, disconnect BLACK cable clamp from battery negative terminal. Disconnect RED cable clamp from battery positive terminal.
Disconnect RED cable clamp from battery positive terminal on disabled vehicle.

Well, our M5 had a dead battery one day, and if anyone knows, M5's are electronics HOGS. The standard battery is HUGE - weighs about 80lbs and is 110amp hours.
When it died I tried to start it with our Honda since it was already parked in a convenient spot. Tried a bunch even holding the revs on the Honda at 3K for a few minutes trying to charge the battery.
Got frustrated and decided to try it with the truck. Hooked it up. Waited 1 minute with the truck idling. Revved the truck to 3K and the M5 started first try (it ALMOST didn't make it, but the last kick it fired up).
We have 4 street bikes and since they aren't ridden enough (dad's the only one who rides them), the batteries die quite a bit in a couple of em. My dad jumps em all the time off the truck (even with the truck off).
