Nissan Sentra Owners Manual: Jump starting

Nissan Sentra Owners Manual / In case of emergency / Jump starting

To start your engine with a booster battery, the instructions and precautions below must be followed.

WARNING

If done incorrectly, jump starting can lead to a battery explosion, resulting in severe injury or death. It could also damage your vehicle.
Explosive hydrogen gas is always present in the vicinity of the battery. Keep all sparks and flames away from the battery.
Do not allow battery fluid to come into contact with eyes, skin, clothing or painted surfaces. Battery fluid is a corrosive sulfuric acid solution which can cause severe burns. If the fluid should come into contact with anything, immediately flush the contacted area with water.
Keep battery out of the reach of children.
The booster battery must be rated at 12 volts. Use of an improperly rated battery can damage your vehicle.
Whenever working on or near a battery, always wear suitable eye protectors (for example, goggles or industrial safety spectacles) and remove rings, metal bands, or any other jewelry. Do not lean over the battery when jump starting.
Do not attempt to jump start a frozen battery. It could explode and cause serious injury.
Your vehicle has an automatic engine cooling fan. It could come on at any time. Keep hands and other objects away from it.

Turn the ignition switch to the “LOCK” position.
Remove the vent caps on the battery (if so equipped). Cover the battery with an old cloth to reduce explosion hazard.
Connect the jumper cables in the sequence illustrated ( A , B , C , D ).

CAUTION

Always connect positive ( ) to positive ( ) and negative ( ) to body ground (for example, strut mounting bolt, engine lift bracket, etc.) — not to the battery.
Make sure the jumper cables do not touch moving parts in the engine compartment and that the cable clamps do not contact any other metal.

Start the engine of the booster vehicle and let it run for a few minutes.
Keep the engine speed of the booster vehicle at about 2,000 rpm and start the engine of the vehicle being jump started.

CAUTION

Do not keep the starter motor engaged for more than 10 seconds. If the engine does not start right away, place the ignition switch in the OFF position and wait 3 to 4 seconds before trying again.

After starting the engine, carefully disconnect the negative cable and then the positive cable.
Replace the vent caps (if so equipped). Be sure to dispose of the cloth used to cover the vent holes as it may be contaminated with corrosive acid.
