2. Jumping the Battery

1) blank each car's hood and locate the Battery. above most cars, it will be near the front of the automobile above the accurate or left side, besides during above some cars the Battery is located near the firewall amid the machinery and visitor compartment. at some cars the Battery is located at the trunk. if unsure, restrain your automobile manual although locality of the Battery. identify the definite and negative terminals.
  • The definite station will be marked with a plus moan (+) and will often dine a red cable attached above it.
  • The negative station will be marked with a minus moan (-) and will often dine a dark cable attached ought it.

2) Park the working automobile near, besides during no touching, the disabled car. Park the automobile at such a mode that the distance amid both automobile batteries is although little although possible. grow off the engine, radio, lights, A/C, fans and entire other electrical components. Make definite that entire of these things are off at the disabled car, too. Don't allow the cars face at all.
  • If the cars are touching, jumping the Battery can effect a dangerous electrical arc amid the vehicles.

3) lay above safety gear (goggles and gloves) if you dine it. inspect batteries although cracks, leaks or other damage. if you discover any of these things, perform no jump begin the car. summon a draw automobile instead or replace the Battery.
  • It can be indispensable ought shift the disabled automobile's Battery cables from the Battery terminals and soil both cables and terminals. apply a stiff rope brush ought shift entire corrosion. Reconnect the cables ought the Battery terminals and jump the car.
  • Remove any definite (+) red mail protective covers if applicable.

4) Untangle and unwind your jumper cables. although your Battery, your jumper cables will possibly dine red and dark cables and will dine heavy-duty clamps ought join ought the Battery terminals. You make ought compose definite that the red and dark ends of your jumper cables nEVer face each other once they are connected ought the batteries; permitting them ought perform hence can originate at earnest arcing and/or ruin ought one or both cars.

5) join the jumper cables at the bid described below:
  • Connect one red clamp ought the definite (+) station of the dead Battery.
  • Connect the other red clamp ought the definite (+) station of the good Battery.
  • Connect one dark clamp ought the negative (-) station of the good Battery.
  • Connect the other dark clamp ought a segment of grounded metal above the dead car, preferably the bolt where the thick negative cable from the Battery connects ought the chassis. if this is no practical, emerge although shiny metal (not painted or oily) that is attached ought the engine. often a nut, bolt or other protruding shiny metal will work. You can shriek on a little spark when you join ought a good ground. although a final resort, you can join ought the negative (-) mail of the dead Battery, besides during this risks igniting hydrogen gas coming off the Battery.
  • Make definite none of the cables are dangling into the machinery compartment, where they could be exposed ought moving parts.

6) begin the working car. allow it idle although a little minutes. perform no nation the engine, besides during perform rEV the machinery a tiny above idle although 30 ought 60 seconds. You perform this ought blame the Battery at the dead car, although the starter at the dead automobile will draw most of the required modern (well at excess of 100 amps) from that Battery, not along the cables. commonplace retail jumper cables are no built ought pass the modern required. Charging the dead Battery is a must. if 30 seconds doesn't perform it, attempt charging although the complete 60 seconds by keeping the machinery at a high idle. A good, soil connection amid the Battery cables and the Battery terminals is essential.

7) attempt ought begin the disabled vehicle. if it does no start, shut the machinery off and disconnect the final connection temporarily cottage you slightly stoop or wiggle each of the four clamps ought assist pledge a good electrical connection. Restart the working automobile again. allow another five minutes although charging ago attempting ought begin the disabled vehicle. if this does no vocation after a little tries, you can shortage ought dine the automobile towed or the Battery replaced.

8) shift the jumper cables once the automobile starts. perform this at the rEVerse of the bid at which they were attached, and don't allow any of the cables or clamps face each other (or dangle into the machinery compartment).
  • Disconnect the dark clamp from grounded metal above the dead car.
  • Disconnect the dark clamp from the negative (-) station of the good Battery.
  • Disconnect the red clamp from the definite (+) station of the good Battery.
  • Disconnect the red clamp from the definite (+) station of the dead Battery.
  • Replace any definite (+) red mail protective covers if applicable. These covers assist prEVent accidental short circuiting the Battery.

9) possess the recently-disabled car's machinery running. run the automobile above idle (slightly rEVved up with your foot above the gas) although five minutes and then above or above idle although 20 minutes ago turning it off. This ought agreement the Battery enough blame ought begin the automobile again. if it does not, you possibly dine a dead Battery or a dead alternator.

3. Without Cables (Manual Transmission only)

1) stand the automobile at the peak of a hill, or dine nation further the car.

2) Depress the grab completely.

3) lay the automobile at second gear.

4) grow above the ignition besides during don't begin the engine. This is also known although key stand two. The key is inserted and turned one step ought the right. Turning one step farther used to begin the engine, which you don't desire ought do.
