Audi (ACC) Adaptive Cruise Control

Dec 5

Adaptive Cruise Control is an optional feature on the 2009 A4, A5, S5, A8 and Q7. This feature uses radar to sense forward moving vehicles in front, to maintain a predetermined distance and speed. Adaptive Cruise Control will apply both brake and throttle as needed to keep your desired speed while maintaing a safe distance with the vehicle ahead of you. If there is no traffic in front of you the Adaptive Cruise Control will simply maintain your speed. Adaptive Cruise Control will not react to stationary objects such as animals in the road. Audi braking guard will react and a chime will be heard and the brakes will be applied (however not at full force) to alert the driver. Also, if the weather conditions are poor, such as heavy fog or snow, the Adaptive Cruise Control will be disabled. It goes with out saying that the driver of the vehicle should always have full control and only use this system as a suplementry comfort device.

On the A8 and Q7 the Radar system is not visable unless the front bumper is removed. However as pictured above on the 2009 A4 the Radar system is exposed and visable in the lower right front grill. This goes for the A5 and S5 as well.

Can this be added by after market or Audi OEM? I have an 06 avant and it was an option. Can buy the built in one and add it in?

1. Performance

Every part in the machine counts.

With our vehicles being developed from the ground up around the world famous & award winning Quattro All-wheel drive, it is no wonder we are the leader in performance.

With countless victories and developments in Le Mans, Rally racing, Pikes Peak, and touring car championships, we build the most competitive All-wheel drive cars in the world. If you are looking for that unfair advantage, welcome to Audi, you have found it.

2. Safety

Why die, when you can live?

Brought to you by the company that pioneered safety standards and crash testing almost 100 years ago, with Audi there is no compromise in safety.

Available with technical advancements such as side guard head protection, Side Assist, adaptive headlights, three point safety belts and many other award winning safety systems as well as L.E.D lighting.

3. Design

Everyone wants to look good right?

Bold dynamic lines with moving surfaces, coupe like design and an aggressive stance on the road whether moving or standing still.

Audi has set itself apart from the rest of the industry with driver oriented cockpits and the leader of interior craftsmanship, materials and fit and finish. Keep in mind our extensive use of aluminum, space frame technology and low center of gravity give you that true Audi experience inside and out.

4. Versatility

Sometimes abundance is not enough.

If you want it, Audi has it. And if you have heard of it, it is most likely an option. Audi builds the most versatile cars in the world. Four door sedan or sport back, Coupe or Sport utility vehicle, big or small, front wheel drive or Quattro, gas fuel or diesel - and you still have to pick a color.

We build vehicles that will truly win races and pick up the groceries on the way home. If you let an Audi tell you it's story, it will never disappoint or disconnect you from the experience.

5. Value

Yes, fair value exchange does exist.

Whether you go with a new Audi and get a 4-year 50k mile warranty, or the certified pre-owned Audi with the most comprehensive 300 + point inspection and up to 6 years, 100k miles, you will not only get the best car on the market,
you will gain piece of mind!

And really, you can't put a price on that.
