Try to boost it. Jump-starting a vehicle takes just a couple of minutes, saving you at least an hour or so of waiting around for the breakdown firm to arrive.
Park the broken down car near the booster vehicle, making certain that the two cars aren't touching. Make sure that the batteries of the 2 cars are near enough to connect to the jumper cables. Turn off the ignition on both vehicles, put on their handbrakes and set them into neutral or park. Shut off both cars lights, if they're in a position that may be a hazard to other auto-mobiles keep their hazard lights on.
To jump-start an auto you want top quality jumper wires, it is wise to have a set of cables with you at all times. The clamps have to be clean and corrosion free as do the terminals on both auto-mobiles batteries.
Start by clamping the red wire onto the + (positive) terminal on the battery of the dead auto-mobile then onto the positive terminal of the booster auto. Repeat with the black wire, but connecting to the - (negative) terminal on the booster car and to a paint free spot within the engine compartment on the dead auto or the engine block. Ensure that the cables aren't coming in contact with any bit of the engines that may move when the auto-mobiles are started. Stars the booster vehicle first leave the engine to tick over for a couple of minutes, and then start the broken down auto. Let both vehicles idle for 1 or 2 minutes whilst hooked up.
If the broken down car doesn't start after 2 or 3 tries don't keep trying. To do so, would drain the booster vehicle's battery and may damage either or both of the auto-mobiles. When you disconnect the cables, take care not to let the cables come in contact with any moving part of the engine or touch each other. Do not turn off the broken down vehicle's engine; you will need to drive several miles to allow the battery to recharge. Not doing so will mean you can't re-start the vehicle without jump-starting it once again.
