<p>Chain requirement FAQ’s. Per dept of transportation; not sure about the rental rules. I seem to remember having an Audi AWD, that if you put on chains, voided the warranty. </p>
<p>[Chain</a> Requirements](<a href=“http://www.dot.ca.gov/hq/traffops/trucks/ops-guide/chains.html]Chain”>Traffic Operations | Caltrans)</p>
<p>"If I have 4-wheel-drive, do I need to carry chains?</p>
<p>Yes. Even though weather conditions may not warrant the use of chains on 4-wheel-drive vehicles at a particular time, to enter a chain control area, you must have a set of chains (for one drive axle) for your vehicle in your possession. If conditions worsen or you have trouble controlling your vehicle, you must stop and install the chains."</p>
<p>"Is “all-wheel drive” the same as 4-wheel drive?</p>
<p>Yes. Even though all-wheel drive systems may differ mechanically from conventional 4- wheel drive systems, for the purposes of chain control, all-wheel drive is considered the same as 4-wheel drive."</p>
<p>"The manufacturer of my vehicle recommends that chains not be installed on it. Do I still have to put on chains?</p>
<p>Yes. Many vehicles which will not accommodate conventional link-type chains will accommodate cable chains or other devices such as “Spikes Spider.” If your vehicle is not equipped with some type of tire traction device, it is neither safe nor lawful for you to enter a chain control area. If you choose not to install tire traction devices on your vehicle, you may not enter a chain control area."</p>

<p>Folks around here (okay, we…) buy AWD just to not have tow worry about it. It would be pretty unusual to need chains , ( and still be on the road!), in an AWD.</p>
