What You Can do Lock all your doors and keep your windows up at all times, even while driving. Never leave your keys in your car when you are not in it, even if you stop to pick up your mail. Never leave your vehicle running unattended. Park in a well lighted and busy areas. If you use the lighter receptacle for a telephone, radar unit, etc., remember to remove the item when leaving the vehicle and reinsert the lighter.
Thieves look for empty receptacles.
Get a theft deterrent and always use it. Deterrent types include alarms, ignition kill switches, collars, steering column bars, boots, etc. Also consider locks for radio, tape decks, batteries and gas tanks. When you park in a commercial garage, lot or valet, never leave an identification tag on your key ring and leave only the ignition key with the attendant. Park with your front wheels turned sharply to the left or right, making it difficult for a thief to tow your vehicle.
