Nissan Sentra Owners Manual: 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.
