Safety – Top 10 safety features
Feb 17th, 2010 by Mohan

  • Tire-pressure monitoring
    The National Highway Traffic Safety Administration has required that all U.S. passenger vehicles weighing 10,000 pounds or less be equipped with a tire-pressure monitoring system by the 2008 model year. But it’s already a safety feature in most new autos. (For example, BMW offers this as standard equipment on all of its models.) Sensors at the wheels are able to alert you if the air pressure is too low by an audible warning, a light on the instrument panel, or both. You may also see more cars with run-flat tires (the Corvette, among the current offerings), which allow a vehicle to continue to run at a relatively high rate of speed for 50-plus miles.
  • Adaptive cruise control/collision mitigation
    Modern cruise control goes beyond just maintaining a constant speed. Thanks to sensors and the use of radar, cruise control can now adjust the throttle and brakes to keep a safe distance from the vehicle in front of you if there are changes in traffic speed or if a slowpoke cuts in. If the system senses a potential collision, it typically will brake hard and tighten the seatbelts. Once it knows the lane is clear or traffic has sped up, it will return your car to its original cruising speed, all without your input. Of course, you may override the system by touching the brakes. The Mercedes-Benz and Maybach systems go by a less obvious name.
  • Blind-spot detection/side assist/collision warning
    This technology is designed to alert you to cars or objects in your blind spot during driving or parking, or both. Usually it will respond when you put on your turn signal; if it detects something in the way, it may flash a light in your mirror, cause the seat or steering wheel to vibrate, or sound an alarm. This is more of a short-range detection system.
  • Lane-departure warning/wake-you-up safety
    This is similar to blind-spot/side-assist technology but with more range. It judges an approaching vehicle’s speed and distance to warn you of potential danger if you change lanes. It can also warn if it determines your car is wandering out of the lane, which could be useful if you become distracted. This could come in the form of a vibration through the seat or steering wheel, or an alarm. Down the road expect lane-departure warning to even be able to monitor body posture, head position and eye activity to decide if the driver is falling asleep and the vehicle is behaving erratically. At that point, the system may even be capable of slowing the car down and engaging stability control. Just in case.
  • Rollover prevention/mitigation
    Most automakers offer an electronic stability control system, and some offer a preparation system (seatbelts tighten, rollbars extend). However, what we’re talking about is more intelligent than that. If the system senses a potential rollover (such as if you whip around a corner too fast or swerve sharply), it will apply the brakes and modulate throttle as needed to help you maintain control. Daimler Chrysler calls it Electronic Roll Mitigation, Ford named it Roll Stability Control, and GM’s is Proactive Roll Avoidance. Range Rover’s is Active Roll Mitigation, while Volvo’s is called Roll-Over Protection System. But they all have the same goal.
  • Occupant-sensitive/dual-stage airbags
    All humans are not created equal, and airbags are evolving to compensate in the form of low-risk, multistage and occupant-sensitive deployment. Technology can now sense the different sizes and weights of occupants as well as seatbelt usage, abnormal seating position (such as reaching for the radio or bending to pick something off the floor), rear-facing child seats and even vehicle speed. While driver, passenger and side curtain airbags are nothing new, sensing airbags are popping up (so to speak) everywhere.
  • Emergency brake assist/collision mitigation
    This brake technology is different from an antilock braking system or electronic brakeforce distribution, in that it recognizes when the driver makes a panic stop (a quick shift from gas to brake pedal) and will apply additional brake pressure to help shorten the stopping distance. It may also work in conjunction with the smart cruise control or stability control system in some vehicles if it senses a potential collision. It is often called brake assist, although BMW, for example, refers to it as Dynamic Brake Control.
  • Adaptive headlights and/or night-vision assist
    Night vision can be executed in different forms, such as infrared headlamps or thermal-imaging cameras. But no matter the science, the goal is the same: to help you see farther down the road and to spot animals, people or trees in the path — even at nearly 1,000 feet away. An image is generated through a cockpit display, brightening the objects that are hard to see with the naked eye. Adaptive headlights follow the direction of the vehicle (bending the light as you go around corners). They may also be speed-sensitive (changing beam length or height), or compensate for ambient light.
  • Rearview camera
    Rearview cameras not only protect your car, but also protect children and animals from accidental back-overs. Backing up your car has graduated from side mirrors tilting down or causing chirps and beeps to real-time viewing. New-school tech involves a camera that works with the navigation system to provide a wide-open shot of what’s happening behind you to help with parking or hooking up a trailer.
  • Emergency response
    There are a variety of ways vehicles now and in the future will handle an emergency situation. For example, Daimler Chrysler’s Enhanced Accident Response System (EARS) turns on interior lighting, unlocks doors and shuts off fuel when airbags deploy, while Volkswagen’s also switches on the hazards and disconnects the battery terminal from the alternator. In addition, GM’s On Star and BMW Assist both alert their respective response centers of the accident and make crash details available to emergency personnel.

    car buying tips
    Feb 14th, 2010 by Mohan

    When buying a new, recalls and defects are always a concern. What is a defect? Why did they do a recall? Where can I report a possible defect or need for a recall? These are all very important questions and can sometimes be tough to find answers to. In the section on Motor Vehicle Defects and Recall Campaigns all your questions, and even a few you didn’t know you had, are answered. Understanding a recall or a defect on your car can save you a great deal of money. In the event of a recall on part of your car, the dealership where you bought it will fix the recalled part for free. If you didn’t know this, you might be out the money that you paid to get the part fixed elsewhere. This section is very informative and helpful. You might even want to take a look at it before you buy a car so you will know what questions to ask the dealership about and recalls or defects they may have had.

    Nothing beats the smell of a new car, the thrill of driving away in a car that is yours, one that’s never been owned by anyone else, but it comes at a price in the form of depreciation. You can virtually write off 20 per cent of the purchase price the moment you drive away from the dealer because it’s then a used car. Cars depreciate faster in the first two or three years of their life and the new car buyer has to cop that for the pleasure of being the first owner. By buying used it’s possible to avoid the heaviest depreciation. Cars will still depreciate in their latter years, but at a lower rate.

    • New car buyers can choose the colour of their car, the trim colour, the engine, transmission and other options and accessories, but used car buyers have to take what’s available.
    • New car buyers have the reassuring backup of a new car warranty so they know that if anything goes wrong they won’t be up for a big repair bill. Anyone buying from a used care dealer will also have a warranty, but it won’t be for as long as the new car warranty. Private buyers don’t have any warranty.

    Negotiating with Dealers

    It’s a buyers market which means you can bargain with dealers for a better deal, but you need to be prepared for the battle.

    • Do some homework on market values before you go shopping so you know the value of the car you’re buying and the value of your trade-in. That way you’ll be better placed to barter with the dealer.
    • Have your finance arranged before you go shopping, but don’t tell the dealer. Dealers will often cut the price of a car believing they’ll make money on the finance.
    • Don’t settle on the first car you inspect. Visit a number of dealers and compare deals before making a commitment.
    • Look for a dealer well stocked with the car you want and he’ll be more prepared to deal.
    • Shop towards the end of the month when dealers are looking to get their quotas up.

    Financing your wheels

    Few of us are able to hand over a wad of cash to pay for our car, we all need finance for the purchase.

    • Before you start work out how much you afford to pay, and how much you can afford to repay.
    • Don’t be tempted to use your credit card to pay for your car, the interest rate on credit cards is generally very high.
    • Shop around to save money.
    • Finance through dealers is the most expensive, dealers are on-selling the finance to you and they are making a profit on the deal, so cut out the middle man and go straight to the source of the finance.
    • Banks offer finance at a cheaper rate than the dealers, but approval can take time.
    • Independent finance companies specializing in car finance often have the lowest interest rates, and some offer fast approvals with an on-line service.

    Where to Buy

    • Buying from a dealer gives you the security of a warranty. By law dealers have to give you a warranty which gives you some recourse if something goes wrong with the car later.
    • Dealers also have to guarantee ownership of the vehicle, that there is no outstanding finance on it which might complicate matters later. They also have to guarantee the odometer reading.
    • It’s possible to buy cars cheaper at auction, but there are risks. There’s little chance to check a car over, there’s no chance to drive it, so you take a risk on its condition. The auction environment is not one for the faint hearted, it’s fast moving with lots of little nods, winks and gestures for those in the know. Spend the time to visit auctions to become familiar with them before attempting to join in the action. It’s a good idea to take along someone with mechanical knowledge to help you assess the cars before the auction starts.
    • Buying privately can be a way of saving money, but it can be risky for the unwary. There is no comeback with a private purchase, once you’ve driven away you’re on your own.

    Before you buy a car ask yourself:

    • What kind of driving do you do?
    • Off road? Around town?
    • What features matter to you?
    • Air-con? Safety? Power?
    • What’s your price range?
    • Where will you be parking?
    • Do you have a garage or only on-street parking?
    • What kind of insurance can you afford?

    Tips for car maintenance
    Jan 28th, 2010 by Virupakshan K 46227

    How to check the engine oil

    Place your car at the level spot. Stop the engine. Wait for a while to let the engine oil to pour down to the oil pan. Pull the engine oil dipstick. If you don’t know where is the engine oil dipstick, check your owner’s manual, usually it has a bright handle saying “engine oil”.
    Wipe it off with a clean rag or tissue. Then insert it back all the way down into its place.
    Now, pull the dipstick again and check the oil level. Normally it should be at “FULL” mark. For example, here you can see that it’s a bit lower. It’s not a big problem yet, but it’s better to top it up. Check the oil condition: If it’s way too black, it’s definitely time to change it. If it’s slightly-brown, it’s O.K. If it’s dark-brown, but still transparent, it’s admissible but it’s better to change it soon.
    If it’s white (coffee with milk color) it means the engine coolant mixes with the engine oil because of some internal engine problem, for example, blown head gasket – have your car inspected.
    How to top up the engine oil:
    It would be better to add the same type and brand of the engine oil as you already have in the engine. Add a little amount of the oil as it’s shown in the image. Wait for a minute to let the oil to pour down. Check the oil level again with the dipstick. If it’s still low, add some more. But don’t overfill it. Don’t forget to install the dipstick back and close the oil filler cap when you finished.

    Engine coolant

    Low coolant level will cause engine overheating, which may cause serious damage to the engine.

    How to check the engine coolant level:
    The coolant level should be between “LOW” and “FULL” marks in the coolant overflow tank as in the picture. If it’s lower, top it up. If there is no coolant in overflow tank or you have to top it up quite often, have your car inspected in the garage, possibly there is a coolant leak.
    Never open the radiator or coolant overflow tank when the engine is hot!

    When engine temperature is reduced (few minutes after the engine has been turned off) , simply add a coolant into the overflow tank to “FULL” mark.

    Tires

    Check the tire pressure regularly – at least once a month. If you don’t have the tire pressure gauge, it’s really worth to get one. You can find the recommended tire pressure in the owner’s manual or on the tire pressure placard (see photo), which might be located somewhere on the car (e.g. on the driver’s door opening, inside the gas tank, inside the glove box). The maximum pressure listed on tires is NOT the proper pressure!
    Rotate tires at every second oil change – it will insure all tires wear equally.
    Feel vibration at cruising speed? – have your tires balanced.
    There is a safe limit of the tread wear. If the tire is worn below this limit it’s unsafe to drive; your mechanic can check your tires for you.
    Uneven tire wear indicates alignment problem.
    Improper alignment causes increased tire and suspension components wear and poor handling. In worst case, improper alignment may throw your car into a skid, especially on a wet or slippery road. If a car pulls aside, wanders or feels unstable on the road, have the alignment checked. Properly done alignment will make your car’s ride a lot more enjoyable.


    Taking care of small concerns in time may save you a lot more

    As soon as you feel there is something wrong with your car like any kind of irregular noise, vibration, shimmer, or you note some leak or any warning light comes on while driving or anything that seems to be irregular – have your car inspected at a dealer or a garage as soon as you can – it might be unsafe to drive. It’s definitely better to check any small problem before it will cause something serious.

    Regular mechanical inspection

    For your safety, I recommend to have your car inspected regularly, at least once a year, by a mechanic. I mean not just visual inspection by one of the fast lube places, but a mechanic that can lift your car and check major components such as brakes, suspension, etc., while having your tires rotated, for example. This is because many components (e.g ball joints), can not be inspected visually.
