If I leave a car on with keyless ignition, will it eventually turn off by itself if I’ve walked away with the key?
Well in that case the car won’t turn off by itself.When you have a smart key access fob it is obviously needed to be inside the vehicle to turn the ignition on and drive off.Yes, someone could literally throw it out of the window while you are driving may be you have a little child that would pick it up and throw it somewhere out of the car.However, if it is thrown out of the window while you are driving the car, so now your vehicle will not display any information that you just lost the key or about the key missing from the vehicle which is a bit scary because you don’t really get to know that you lost your key until you get to the destination you were going and open the door. Once you open the door the vehicle will show the information and message will be pop up “No key detected” and this is the moment when you get to know that you lost your key.Now, if you turn off your ignition then there is no way to turn it on without a key and at this moment you arr stuck. But just when you turn the car off vehicle, a message will pop up “Restart now or key is needed” and at this point of time you only have few seconds in your hands to turn on the vehicle ignition else you will stuck there.Other case is, if you just step in your vehicle and turn on the ignition and still the car is parked and someone takes away your key, and as you just start to drive the vehicle, it will immediately show that the key is missing or key is not detected. But the ignition won’t turn off until you do that.
Does running the AC in your car use additional fuel?
Yes it does. (That’s your short answer, I love cars and engineering so the following is a nice long answer)A vehicles air conditioning system removes heat from air through a phase change. The entire system is sealed under vacuum, and in these conditions, the liquid coolant in the AC system will boil at a very low temperature. When the liquid boils it expands rapidly and pulls heat from the system.Experiment: place your hand in front of your mouth, open your mouth really wide and breath a heavy lung full of air into your hand. Notice how hot the air feels? Now make a very tight “o” with your lips and blow onto your hand, almost like you’re whistling. Try to breathe out at rate where the gust of air coming from your mouth is moving about the same speed as it was in the first part of the experiment so you can rule out velocity. Notice this is cool? The air is coming from your lungs both times so why does it behave in this way? The science is that when you leave your mouth open and puff the air out, it travels as one big mass carrying the heat of your body. When you make a small opening, the air comes out into the atmosphere and starts to spread out dissipating heat.Now back to your car. The AC uses an evaporator, a condenser, and a compressor. The evaporator is inside the cabin of the car, and it is where the liquid refrigerant becomes a gas before a fan inside your car blows the hot air through and removes heat making you feel cold air. The gas moves back through the system where it is brought back to a liquid phase in the condenser. In order to condense more easily, the gas is compressed by the compressor. Compressing this gas requires quite a bit of energy and this energy comes from a belt running off of an accessory pulley on your engine. When you turn in the AC, a compressor clutch engages the compressor to he engine and put an extra load on the engine. The engine must burn more gas to overcome this load and it is being less efficient. It also takes in slightly more load from the alternator to pull the current to run the blower fan motor in the dash board that the AC uses, but this loss is negligible in comparison to what the compressor needs.

Most of those models, you can reach under the dash, feel around on the switch, you'll feel a button , depress this and pull switch knob out, then you can unscrew the slotted nut on the front of switch, with flat screw driver, just bump it with the screw driver until it gets loose, then unscrew, pull out , unplug wires and replace in reverse. GOOD LUCK
What's the penalty for driving a right-handed car in the U.S.?
The position of the steering wheel is no (legal) problem, but you do need to make sure that the headlight beam pattern is correct for driving on the right side of the road. Headlight beams are designed to cut off at the center of the road to avoid blinding oncoming drivers, but provide more illumination to the shoulder of the road in case there are obstacles (or animals) there that you need to avoid. Swapping sides, your headlights now illuminate the wrong area.Various solutions to the headlight beam problem exist, from things as simple as carefully-placed stickers on the headlight lens, to fully replacing the bulb and lens assembly. Failing to do something about it isn't guaranteed to get you in legal trouble, but if your lights shine in a police officer's eyes at night you may get a citation. There may also be problems if there is an inspection when you try to register the imported vehicle.
What does L mean in an automatic car?
P, R, N, D, these are for the most part letters on your automatic transmission that you're likely comfortable with. In any case, you may infrequently, if by any stretch of the imagination, move into "L" on the gear move. So what does this letter remain for? What's more, would it be advisable for you to utilize it?L remains for low gear. At the point when your auto is in drive, or D, the automatic transmission will change through the gears as your speed increments. At the point when your auto is in low, or L, the transmission won't move. Rather, it stays in a low gear, and less fuel is infused into the engine. This gives you less speed, yet what you yield in speed you compensate for in engine torque. Essentially, utilizing low gear gives the engine more power.Torque is helpful when you're towing something with your automatic. Towing requires more torque, however in the event that you tow in drive it puts more strain on your engine as the transmission spins through the gears. Keeping it in low gear gives you a chance to keep the torque, which makes towing simpler, and decreases the weight on your engine. Another reason you may utilize low gear is for driving up a slope so as to give your engine the power to get up the slope without over-focusing on it. Low gear is likewise helpful for driving in snow or on frigid streets, since it diminishes your speed and gives you more control over the vehicle.http://salemcarservices.in/servi...
Is it still possible to hotwire a modern car?
No.“Hotwiring” is where you bypass the ignition lock/switch mechanism and simply join up a series of wires to start the car. The “security” is the ignition lock and nothing else.When a key is typically turned in the lock, all it does is turn a cirular switch pack which joins up the correct wires to complete connections.Hotwiring is connecting the wires by hand, it sounds technical and complicated, the reality is very much different.However, since the early 90’s in America and ’93 in Europe, cars have had passive immobilisers fitted whereby there is a reader around the ignition barrel that looks for a signal from a chip in the key, no chip, no signal, no start.And its very difficult to bypass if you’ve only got 2 minutes to steal the car, as the lack of signal means the ECU shuts down various parts of the system like power to the sparkplugs, power to the crank sensor, power to the fuel pump.However, earlier systems could be beaten quite easily by doing one of two things.Either fit a “performance” chip to the ECU system such as a Superchips type. This replaces the main chip in the ECU for one with supposed better fuelling maps and raised rev limits, but also, has no security anymore which renders the immobiliser system inert.The other way is to goto a junkyard, and remove the ECU, reader and chip from a car, and simply swap them all over into the one you want to steal, it can take time, but it can all be done noiselessly, once done, you can then break the ignition lock, rip off the ignition switch, hold your replacement chip by the reader and use a screwdriver to turn the ignition switch and the replacement set will start the car.But hotwiring in the conventional sense on modern cars is dead, however thieves are now stealing modern prestige cars QUICKER than they could the older stuff because technology is modern cars undoing.
How do I jump start a car without cables?
This question needs to be rephrased. How do you start a car with a dead battery without jumper cables?If the battery is dead from being discharged such as leaving lights on, then a simple solution is to use a charger to recharge the battery for a short period of time and then start the car and let the alternator fully recharge the battery. Of course, if you don’t have jumper cables you probably do not have a charger or the car may not be near a plug outlet. Try to borrow some jumper cables or a jump start kit mentioned by others from a friend or a good Samaritan who sees your plight.If you cannot charge it or jump it and no friends have equipment, remove the battery and take it to a retail store in another vehicle to have it checked and charged. This will save you some money if the battery can be recharged and you don’t need the car right away. If the battery is bad, you will need to get a new one anyway. If the battery is simply discharged, you will need to discover if there was a load left on or the vehicle charging system was not working (you should have seen warning lights).If you are in a hurry, in a remote location and late at night call a rescue service like AAA. Expensive but effective.
