Here's how to jump-start your battery using another car:
If possible, bring the two cars together nose to nose, about 18"
apart. Be sure you're parked well away from traffic. Make sure both cars have their parking brakes on.
Make sure both cars are
turned off. Put automatic transmission cars in Park. Put manual transmission cars in Neutral. Set the parking brake firmly so the
vehicle cannot move.
Determine which terminals are positive and negative on both batteries. Look for "+" sign or red indicator
for positive, "-" sign or black indicator for negative. The positive terminal is usually wider than the negative.
Caution!! Once
you begin the next steps, do not touch the metal portion of the jumper cable clamps to each other or any part of the car except the
proper battery terminal.
The jumper cables are marked with colors or stripes to help you keep track of the two separate wires.
Attach one end of the positive cable clamp to the positive terminal of the dead battery (the positive cable may have a stripe, or
if the cables are marked with red and black, the red cable is positive).
Attach the other end of the positive cable to the positive
terminal of the good battery.
Attach one end of the negative cable to the negative terminal of the good battery.
YOUR CABLES
ARE NOW LIVE! DO NOT TOUCH THE REMAINING CABLE CLAMP METAL PORTION TO YOURSELF OR ANY PART OF THE CAR EXCEPT THE NEGATIVE TERMINAL
OF THE DEAD BATTERY.
Attach the other end of the negative cable to a metal section (bracket, block, etc.) of the engine away
from any moving parts (CAUTION: belts and pulleys can be dangerous). Connecting this cable last, and away from the battery, will avoid
sparks and potential hazards at the battery.
Make certain everyone is clear of the engine compartments - don't allow hands or
clothing to be caught by moving engine parts.
Start the engine of the good car. Allow it to run for 1-2 minutes. Rev the engine
slightly by pressing on the gas pedal lightly.
Start the engine of the dead car. It may take more than one try, but do not try
to restart it more than three or four times.
Caution: Some car's electrical and computer systems may be damaged by running the
engine with a dead battery. Check your owners manual or service provider for guidance.
