Cayenne Knows Your Towing Limits in Los Altos

cay

 

Hello, Cayenne here on a beautiful June day here in  Los Altos.  You know, some Los Altos drivers figure that anything they can attach to their trailer hitch can be towed by their vehicle, including my oversized t-bones. Well, that is not the case. If you're going to do any towing around Los Altos, you should be aware of safety issues, CA towing laws and potential liability.  So you probably already figured it out, we are going to bark about towing limits around town.  So let's get barkin'!

Understanding tow ratings is important for safe towing. A tow rating is the weight limit that your vehicle can safely tow. They calculate the tow rating for every vehicle, but different options on the vehicle can affect that rating. Los Altos drivers need to read the towing section in their owner's manual to get the specific tow rating for the vehicle they own.

Your trailer hitch also has a weight limit, and it may not match the tow rating for your vehicle. Your vehicle may be rated for 10,000 pounds (4,500 kg), but if you have a 2,000-pound (900 kg) hitch limit, you shouldn't be towing more than 2,000 pounds (900 kg). If you tow a 10,000-pound (4,500 kg) trailer on that hitch, it could break free and you would be liable for any resulting damages.

Another example is one popular pick-up truck that has a tow rating of 10,300 pounds (4,600kg). But the owner's manual specifies that a sway control device be used for trailers weighing over 2,000 pounds (900 kg) and that a weight-distributing hitch is required for trailers over 5,000 pounds (2,300 kg). If the vehicle owner tows a 6,000-pound (2700 kg) trailer without a weight-distributing hitch and ends up in an accident, the owner will be held liable for not complying with the towing requirements in CA.

Los Altos auto owners also need to keep in mind that tow weights include the weight of passengers and cargo inside the tow vehicle. So if your tow rating is 7,000 pounds (3,200 kg), and you're carrying 700 pounds (320 kg) of passengers and cargo, you can only tow a trailer weighing up to 6,300 pounds (2,880 kg).

Two numbers that Los Altos drivers should be aware of are the GVWR and the GCWR. These codes are usually imprinted on the inside of the driver's side door. GVWR stands for gross vehicle weight rating. Take GVWR and subtract the total weight of the vehicle, and you have the maximum weight the vehicle can safely carry in passengers and cargo. GCWR stands for Gross Combined Weight Rating. Take that number, subtract the weight of the tow vehicle and the trailer, and you have the maximum weight of passengers and cargo that the tow vehicle and trailer together can safely carry.

This may seem a bit complicated, but you ignore these ratings at your own peril. If you haul or tow loads over the maximum ratings around CA, you become liable in the event of an accident.

Local Los Altos laws require that safety chains be attached when towing a trailer. Some CA jurisdictions may require trailer brakes as well. Others mandate trailer brakes only in certain situations. If you are going to tow a trailer, you should find out the local Los Altos laws regarding trailer brakes and hitches, as well as weight and length restrictions.

To tow safely, CA drivers also need the proper tires on the tow vehicle. Tires need to be in good condition with adequate tread, and they need to have a load rating high enough to handle the weight of the trailer. Your trained Allied Auto Works tire professional can help you select the right tire to use when towing around Los Altos.

Your 's owner's manual is your primary source for auto advice regarding towing since it is specific to your vehicle. Be sure to read it carefully before doing any towing. And as always, keep your preventive maintenance up-to-date, and practice good car care to ensure the safety of your vehicle on the road—especially when pulling a trailer.

Here is my joke of the week, yes, tow related

If there was a film about a car towing a boat, would there be a trailer?

Duke Gives Your Engine Clean Fuel with a New Fuel Filter from Allied Auto Works

duke

Duke here, and your vehicle requires plenty of clean fuel to run.  Today we will bark about keeping your vehicle's fuel clean.  So let's filter threw and get barkin" about clean fuel with a new fuel filter!

If your fuel contains contaminants, your fuel injectors will eventually become clogged up. When this happens, your vehicle engine may not get the proper amount of fuel at the correct pressure to run at peak performance. This hurts performance as you drive around the Los Altos area. It can also lead to the buildup of harmful deposits on valves and in the combustion chamber.

That's why all vehicles, including vehicles, come equipped with a fuel filter. The job of the filter is to clean out little pieces of dirt and contamination. The filter captures the contaminants and keeps them out of the fuel stream. Of course, like all filters, it will eventually get clogged up and need to be replaced at Allied Auto Works in Los Altos.

If your fuel filter is clogged, the vehicle engine can't get all the fuel it needs, and it may sputter at high speeds or quick acceleration. Many fuel filters have a bypass valve that will allow unfiltered fuel through when they are clogged. This keeps your vehicle engine running but doesn't protect it from contaminated fuel.

Los Altos drivers may find that they need to change their fuel filter at Allied Auto Works more frequently as their vehicle ages. Over the years, additional sediment and rust accumulate in the fuel tank and can be drawn into the fuel system.Your fuel filter stands guard at the gates to your engine to protect parts and maintain performance.  So make sure your filter is doing its job and book an appointment today!

I leave you with a Haitian proverb for the week

Cayenne Barks "For Brakes' Sake" (Brake Rotor Service in Los Altos)

cay

For brakes sake, think of how much abuse your brakes take.  Hi Cayenne here and day in and day out, they stop your vehicle when it's going fast and when it's going slow. Maybe your vehicle has been vibrating when you brake, or maybe it seems like your stopping distance is a little bit longer than it used to be. Then it's time to get your brakes checked out.  After all, you have to be able to stop if you want to be safe.  So let's get barkin' for brakes sake!

Nearly all newer vehicles have disc brakes on the front, and many have that type of brake on all four wheels. That makes it likely you'll be getting disc brakes fixed at some time in your vehicle's lifetime.

Knowing how disc brakes work is as easy as riding a bicycle. If your bike had hand brakes, you'll probably remember a mechanism that squeezed a couple of pads on each side of your bicycle wheel when you applied the brakes. Disc brakes are similar; but instead of the bike wheel, there's a metal disc instead. If that disc is warped or has irregularities in it, it's going to vibrate.

It used to be that rotors were thick, and when they warped, a technician could "turn" them to scrape off a layer of metal so their sides were straight again. The latest vehicles are using thinner, lighter rotors with a slightly different construction. Now, it's likely that rotors that are resurfaced this way will not have enough metal left to work safely. In fact, some manufacturers advise only replacing rotors that are worn out.

Newer designs have reduced rotor prices, and in many cases, the labor cost of turning the rotors is higher than buying new. There are times, though, when your rotors can be resurfaced and still meet manufacturer specifications.

If you have a rotor replaced on one side of your vehicle, it might be a good idea to replace rotors on the other side, too.

Maybe you're looking for the new rotors to last longer than the ones that were on there. New technologies can offer a longer lifespan in a premium rotor. Armed with knowing the type of driving you do, you and your Allied Auto Works service advisor can make the best decision on which direction you want to go with your new brakes.

Now that summer is here, I leave you with this quote.

A perfect summer day is when the sun is shining, the breeze is blowing, the birds are singing, and the lawn mower is broken. ~James Dent, in The Charleston Gazette, as quoted in The Reader's Digest, 1994

Duke Is Beginning to See the Light (Check Engine Light Diagnostics)

duke

Good Day, Duke here and you know we have all heard and maybe said the famous quote, "I'm beginning to see the light." but today, we really are dealing with seeing the light in our vehicle, the Check Engine Light.  So let's start barkin' and venture into the unknown of the Check Engine Light!

It's a light many drivers fear they'll see turn on at the most inopportune time.  It's the one on the dash that says "Check Engine," "Service Engine Soon," or it may be simply an engine-shaped light. Your first instinct may be to pull off to the side of the road and turn off the engine.

The truth is that the Check Engine light can be pointing to problems as simple as a loose gas cap. But it could be as serious as a severely misfiring engine.  Don't ignore it because it's there to help you avoid an expensive repair. It is designed to alert you, to tell you something's not quite right.

Your vehicle has a connected system of computers and sensors constantly checking to see that all systems are working the way they should. If something isn't, the system will turn on the Check Engine light.

If it's flashing, that could be serious. Look at some of the other warning lights or gauges, such as heat or oil pressure. They could be telling you your vehicle's problem should be checked right away. In that case, if you can, safely pull off the road and shut the vehicle down. If your vehicle loses power and the Check Engine light is on, try not to push the demands you are making on the engine, such as towing or accelerating hard.

Simply put, a flashing Check Engine light should be checked out by a professional as soon as possible.

If the Check Engine light is on steadily, manufacturers say it means there's a problem, but it probably doesn't require immediate service.  The system is designed to remember the problem it found and store it (as a code) so it can be retrieved later.

When you do bring your vehicle in to have us see what's behind the Check Engine light coming on, we’ll hook your vehicle up to a diagnostics tool that can reveal the clues the engine's computers have stored.  It takes a trained technician to understand those clues, like a doctor who can interpret a patient's symptoms and come up with the correct diagnosis. Some newer vehicles can even be checked remotely.

Once we figure out the problem and repair it, you'll be back on the road again. It's nice to know the Check Engine light is your sentry, standing by to alert you the next time you begin to "see the light."

"I never cared much for moonlit skies

I never wink back at fireflies

But now that the stars are in your eyes

I'm beginning to see the light" ~Ella Fitzgerald
