HONDA S2000 - Manual (Page 220)

Although this seems like a simple
procedure, you should take several
precautions.
Open the hood, and check the
physical condition of the battery.
In very cold weather, check the
condition of the electrolyte. If it
seems slushy or frozen, do not try
jump starting until it thaws.
To jump start your vehicle:
Connect one jumper cable to the
positive (
) terminal on your
battery. Connect the other end to
the positive (
) terminal on the
booster battery.
Turn off all the electrical
accessories: heater, A/C, audio
system, lights, etc. Put the
transmission in neutral, and set
the parking brake.
The numbers in the illustrations
show you the order to connect the
jumper cables.

A battery can explode if you do
not follow the correct procedure,
seriously injuring anyone
nearby.
Keep all sparks, open flames,
and smoking materials away
from the battery. If a battery sits in extreme cold, the
electrolyte inside can f reeze.
Attempting to jump start with a f rozen
battery can cause it to rupture.
