| What can you do to make sure your car isn’t stolen? Well, first and most obviously, lock the car when you leave it. That includes locking the boot for luggage and closing all the windows. Even a tiny break allows a thief to insert a wire to force open the lock button. Of course, don’t leave the keys hanging in the ignition（点火器）. And don’t hide a spare key inside or outside the car - thieves know all the hiding places. If your car breaks down, lock up before you go for help.

You should also have a record of your car’s vital statistics both in your wallet and somewhere at home. This can help with recovery in case of stealing. And finally, it’s a good idea to fix some kind of safety devices. There is a range available from alarm systems that set off a siren（警报）if an attempt is made to interfere with the car in any way, to fuel shut-off systems and time delay ignition systems. Displaying a warning sign will also help discourage would-be thieves. They don’t want to waste time on trying to steal a protected car.
