1. Inspect the outside edge of the drivers side seat in your Chevy vehicle. Look for the buttons labeled 1 and 2. If your Chevy doesnt have them, it does not have the memory seat feature.
2. Sit in the drivers-side seat and adjust the seat to fit your proportions by pushing the power-seat selector up or down to raise or lower the seat. Push it back or forth to adjust your seat-track position. If your Chevy has electronic lumbar, adjust it using the side lumbar control. as well, which will also be saved into your memory seating position.
3. Press and hold the 1 button. Youll hear a chime in about five seconds notifying you that the memory seat is programmed to the current position.
4. Repeat the process for memory position 2. To recall either position, simply press the 1 or 2 button when you enter the car. The seat will automatically adjust to the programmed position.

1. Park the car in a flat, well lit area. Disconnect the negative batter cable from the battery. Lift the front of the vehicle with a floor jack and lower it onto jack stand. Alternatively, you can pull the front of the car up onto ramps to access the starter, since the wheels do not need to be removed for this job.
2. Locate the reinforcing bar that bolts to the chassis between the engine and the gearbox, just behind the engine’s oil pan. Remove the two bolts that hold the bar to the car on either end with a socket and a ratchet. Set the bar aside.
3. Remove the bolts that hold the metal cover on that protects the fuel line where they run through this area of the car. Remove the cover. Pull the fuel lines off of the bracket that holds them in place. Pull the line off for the reverse light switch from the bracket. These are simply unclipped by hand.
4. Remove the bolt that holds the wires that go to the starter onto the starter. Pull the wires off of the starter. Remove the bolt from the reinforcing bracket that supports the weight of the starter. Remove the upper and lower bolts that hold the starter to the gearbox with a socket. Pull the starter away from the gearbox.
5. Install the new starter in the reverse of removal, ensuring that the teeth on the starter engage with the teeth on the flywheel. Install the upper and lower bolts. Reinstall the bolt that fastens the reinforcing bracket to the starter. Reinstall the wires on the starter connections in the proper orientation.
6. Press the fuel lines back onto their bracket. Press the reverse light switch line back onto the bracket. Reinstall the protective plate for the fuel lines. Reinstall the reinforcing bar between the engine and gearbox. Reconnect the battery and lower the vehicle back to the ground.

1. Look for the recommended tire pressure in your Audi manual. If you do not have your manual handy, look on the side of the tire for a tire pressure stamp, or on a sticker on the inside of the drivers side door.
2. Inflate your tires with 32 pounds per square inch (psi) if you cannot find the recommended tire pressure for your Audi. This represents a safe tire pressure average until you know for certain.
3. Let air out of your tires if you wear down the middle of tires only, rather than the sides. This pattern of wear is a sign that you have too much air in your tires. Add more air to your tires if you see tire wear on the inside and outside edges.

1. Press back on the seat position switch to maneuver the seat backward as far as it will go. Locate the plastic caps on the front of the metal seat rails on the floor. Using a flathead screwdriver, gently pry the caps off to gain access to the bolts.
2. Unbolt the forward-most bolts using a socket wrench. Place the bolts in a safe location. Using the seat position switch, move the seat forward as far as possible, making the rear bolts visible. Repeat this process to remove them as well.
3. Reach under the seat and unplug the wiring connector from the power seat control module. Unplug the cable from the heating element if your CLK 320 is equipped with heated seats.
4. Remove the seat from the vehicle. Repeat this process on the other side to remove the second seat. When finished, place the seats back in the car, reconnect the wiring and securely reinstall the bolts and caps.

1. Make sure the vehicle is parked on a flat level surface. Ensure that the car is in gear or in Park. Use a lug wrench to loosen the lug bolts for the wheels. Raise the car with a floor jack and lower it onto jack stands at all four corners. The jacking points will differ depending on the model of BMW that you are working on. Consult your owners manual for the proper jacking points. Remove the wheels and set them aside.
2. Clean the brake rotor, the caliper and any nearby parts with brake cleaner and a clean, dry rag, ensuring that there is no oil or residue on the brake parts. Loosen the two large bolts that hold the caliper to the carrier. These are located on the upper and lower part of the caliper facing the wheel arch. On most newer BMWs these bolts are Torx-shaped bolts that are removed with a star-shaped bit. Some older models use a normal bolt. Slide the caliper off of the rotor and support it with a piece of wire or on a platform while you work to avoid damaging the soft brake line.
3. Remove the two bolts that hold the caliper bracket on. These are located on the top and bottom of the bracket facing the wheel arch. Set the bracket aside. Remove the set screw that holds the rotor on. If it is frozen and will not loosen easily, spray penetrating fluid on it and let it soak in. The set screw is removed with a small Allen bit on BMWs. Make sure you use the properly sized tool to avoid stripping the screw. Pull the rotor straight off of the hub, tapping it from behind if needed to free it. Spray the hub mounting surface with brake cleaner and wipe it down.
4. Clean the new rotor with brake cleaner and a clean rag. Avoid touching it with your bare hands. Slide it onto the hub and reinstall the set screw. Tighten the set screw firmly. Bolt the caliper carrier back on and tighten the bolts. On most BMWs, the outer brake pad fastens to the slots in the caliper carrier and the other one clips into the piston in the caliper. If they have fallen out, reinstall them and slide the caliper and brake pads over the rotor. Tighten the bolts that hold the caliper on. Repeat the above steps for the other three corners of your BMW. Replace the wheels and lower the car to the ground. Pump the brakes until the pedal feels firm.

1. Locate the air filter cover on the top of your BMW 330 engine. It will be a black cover, secured by seven torx screws. You should see it near the center of the engine on top with a black flex hose running from the cover to the engine.
2. Remove torx screws with torx screwdriver from top cover of air filter. Lift the cover up. It will not come all the way out, just enough to give clearance to remove the air filter.
3. Unclip the flex hose from the air cleaner to provide room for removal. You will see a pin inserted into the air filter. Pull the pin back and remove the filter from the air cleaner.
4. Replace the air filter with a new filter by pulling the pin back and reinserting the new filter. Replace the flex hose on the front of the air cleaner.
5. Place the cover back on the air cleaner and secure it with torx screws.

1. Fill your gas tank with fuel with the correct octane rating. Many BMWs need premium unleaded; your owners manual will tell you what fuel is best for your model BMW.
2. Accelerate slowly whenever moving from a stopped position.
3. Anticipate stops ahead. By taking your foot off the gas and coasting for as long as you can before you start braking, instead of accelerating to stoplights and stop signs, you can save considerable amounts of gas.
4. Reduce weight by removing items from your trunk and passengers seats. Increased weight is increased burden on your engine and increased burden means that your cars engine must use more gas to move the car.
5. Maintain the recommended tune-up schedule for your car. This will help your engine run better and use less fuel.
6. Replace your BMWs electronic control unit (ECU) with one that is tuned to be more economical. These can be bought from aftermarket BMW parts dealers and will tune your BMWs engine to use less gas. This change will negatively impact your cars speed, but the improvement in gas mileage may be a worthwhile trade-off to you.
7. Make sure your tires are always properly inflated and have adequate tread. Proper inflation levels can be found on the sidewalls of your tires and tread should be more than 1/16th-inch deep.

1. Turn off the car completely and put on your safety glasses and gloves.
2. Open the hood, and locate the bulbs you need to change. The low beam bulb will be closer to the outside of the vehicle, and the high beams are closer to the inside, right behind the light cover near the engine.
3. Turn the bulb holder to the left, and pull it straight off, and then unscrew the burned-out bulb. Put it somewhere out of the way.
4. Twist the new bulb carefully into place using a cloth or clean gloves, without touching it directly.
5. Replace the bulb holder and tighten it into place. If more bulbs need replacing, repeat this process as necessary.

1. Remove the panels for the front bumper, the side front quarter panels and the rear bumper. Replace the rear bumper with an aftermarket bumper that allows two cutouts for the dual exhaust that matches the M3 style.
2. Replace the front bumper with an aftermarket body kit that includes front brake spoilers. On the M3, the front spoilers act to cool the front brakes. The aftermarket bumper need not provide a similar function as long as the two openings at the lower front corners are present to mirror the look of the M3.
3. Replace the two front side panels with 3-series panels with side grilles. The chrome grilles provide ventilation for the E92 M3s 4.0 liter V-8 engine. On the 3-series it will provide one of the distinctive exterior features that differentiate the M3 from a standard BMW 3-series coupe.
4. Add side skirts below the side panels of the 3-series to give the appearance of a lower stance for the 3-series.
5. Replace the wheels with compatible 19-inch chrome wheels. The E46 BMW M3 came with either 18 or 19-inch wheels while the E92 has standard 19-inch chrome wheels.
6. Replace the hood with an M3 hood with a power dome. The M3 engine required a raised section of the hood for clearance, which is commonly called a power dome. From a distance, when the wheels are indistinguishable and the side grilles are invisible, the power dome stands out as a signature feature of E46 and E92 M3s.
7. Add a lip spoiler to the rear trunk lid. The M3 has a subtle spoiler on the rear edge of the trunk. You can have the lid spoiler attached by adhesives for a long-lasting fit.

1. Start the car engine and put it in Park mode then roll down the windows of the car.
2. Sit in the drivers seat and look at the cars pillar which is on the outer side of your seat. There you will see a cable that is running all the way to the car top; this cable is actually connecting the car to the car top. All you need to do is unclip it.
3. Look on the right hand side next to the gearshift, you will notice a red button. Gently pull this button up, continue pulling it up for a few seconds until you observe an irregular blinking within six seconds of doing so.
4. Maintain complete silence so that you can hear the hard-top unlock from its four panels across the car top while you were pulling up the red button. This unlocking will result in the hardtop being elevated by almost an inch or a half.
5. Remove the top carefully.

1. Position the car ramps behind the vehicle and back up onto the ramps slowly. Place the tire stops in position behind the front tires to secure the vehicle from moving during the replacement.
2. Lift the vehicles hood and locate the fuse panel. Remove the bolt securing the panel using the crescent wrench. Remove the fuse responsible for controlling the fuel pump.
3. Find the fuel filter under the rear of the vehicle near the fuel tank. Position the floor jack below the fuel tank in preparation of lowering the tank. You will only be lowering the fuel tank about four inches. Using the crescent wrench, remove both metal holding straps that secure the fuel tank in place.
4. Using the floor jack, lower the fuel tank about 4 to 6 inches to gain full access to the fuel filter. Use the crescent wrench to remove both fuel lines going into the fuel filter. Remove the securing bolt and remove the old fuel filter.
5. Install the new filter and replace the securing bolt. Reattach both fuel lines ensuring the arrows on the filter are pointing toward the front of the vehicle. Using the floor jack, lift the fuel tank back in place and reattach the metal holding straps.
6. Reinstall the fuel pump fuse and reattach the bolt that secures the fuse panel. Remove the tire stops and start the vehicle. Drive the vehicle off the car ramps.
