Air Filter Guide

Air Filter & Cabin Air Filter Care

Vehicle owners often neglect timely air filter replacement. And that’s partly understandable. Things like your oil, belts, tires, and transmission seem like greater priorities. And the difference between regular air and clean air is negligible, right? Wrong! Your air filter (and your cabin air filter) is an important component in your engine. And, replacing it at the appropriate time is an important part of your vehicle’s routine maintenance.

What Does Your Air Filter Do?

An air filter… filters the air. Combustion engines need air to work properly for the same reason a campfire needs oxygen. No oxygen equals no combustion. And you need to remember that our air is less than 20% oxygen. That means, But even ostensibly clean air has contaminants and debris in it. And driving through smoke or swirling dirt will only compound the issue. The air filter blocks harmful particulates from entering your engine, and keeps it clean.

Not only does clean air keep your engine running more smoothly, it protects it. Allowing debris into the combustion chamber can have disastrous effects that reduce the lifespan of your engine overall. So, like with all routine maintenance, make sure you stick to your manufacturer’s maintenance plan, and listen to the advice of the service team at Capital GMC Buick Cadillac.

Diagnosing an Expired Air Filter

The easiest way to tell if you should replace your air filter is to look at it yourself. They’re usually easily accessible – you likely won’t even have to unscrew anything. Just consult your owner’s manual for your air filter’s exact location. If the filter is covered in dirt and dust, then you should probably replace it.

Another less obvious sign that you should replace your filter is diminished throttle response and sluggish acceleration. If your filter is clogged, it will prevent an adequate amount of oxygen from reaching the combustion chamber, and your performance will suffer. Replacing an old, dirty air filter can improve your vehicle’s acceleration by roughly 11%.

Cabin Air Filters

Cabin air filters are important, too. They have nothing to do with your engine, but they do support the healthy operation of your lungs. If you don’t want to breathe in the dirt and smoke that you’re driving through, you should replace your cabin filter roughly every 25,000 kms or one year. Although, your owner’s manual may have slightly different directions. And, if you drive on dirt roads, or somewhere with poor air quality, you’ll probably need to change it more often.

Unfortunately, cabin air filters are a bit more difficult to replace. In many cars, you’ll actually have to remove the glove compartment to access it. While this isn’t prohibitively difficult, it is a bit of a hassle. Usually it’s just easier to let the professionals at Capital GMC Buick Cadillac Service take of it for you.

Cadillac Technology

Cadillac Features and Technology

According to Johann de Nysschen, Cadillac’s Executive VP and President, Cadillac will continue to lead the entire GM portfolio: “Cadillac in the future will be the technology lead brand for General Motors. Technologies will debut in Cadillac first and then cascade down to the other brands.” That idea will be no surprise to Cadillac owners who have been receiving GM’s cutting-edge technology before anyone else. In fact, the brand has been raising the stakes in recent years under the banner of the new Dare Greatly campaign, and many of the Cadillac features and technology lead not only the GM lineup, but the auto industry in general. So, here’s a quick look at some of the most remarkable features you’ll find in the current Cadillac lineup.

Super Cruise

Super Cruise is the world’s first hands-free driving system for the highway. When you engage Super Cruise, a green band on the steering wheel indicates you can take your hands off the wheel. From there, the system is in complete control. It will adjust your speed, brake accelerate and keep you in your lane. Plus, embedded cameras in the dashboard to ensure you remain focused on the road in case you need to retake control. It’s standard on the 2018 CT6 Platinum and optional on the CT6 Premium Luxury.

Front Pedestrian Braking 

Another of the standout Cadillac features is Front Pedestrian Braking. The system uses cameras and sensors to identify pedestrians on the road ahead and alerts the driver to their presence. If a collision is imminent, your Cadillac will brake automatically to mitigate or even prevent the crash.

Bose Panaray sound system 

The Bose Panaray Premium Audio System is simply one of the best automotive sound experiences. You get 34 strategically-placed speakers, including four UltraNearField speakers in the front seat headrests, powerful bass speakers beneath the floor, and a number of clustered, articulated arrays. The sound is clear and precise. Plus, Bose Active Noise Cancellation helps reduce the sound of the road and wind.

Night Vision

Night Vision uses thermal imaging technology to highlight animals and pedestrians at impressive distances in total darkness. Of course, you won’t find this technology on any other widely available passenger vehicle. 

Rear Camera Mirror

Cadillac features

Cadillac’s unique Rear Camera Mirror has made traditional rear view mirrors obsolete. A camera at the rear of your vehicle streams live HD video of the road behind your Cadillac to the spot where most vehicle have a rear view mirror.

Auto Vehicle Hold

Auto Vehicle Hold is another great feature available in most new Cadillacs. Once you come to stop you can remove your foot from the brake. Your vehicle won’t resume moving until you press the accelerator. You don’t need to suffer leg fatigue at long red lights or traffic jams.

Cadillac Escalade

As the brand’s flagship, the 2018 Escalade synthesizes most of these Cadillac features, and plenty more that we don’t have the space to discuss. Perhaps more impressively, it combines the cutting-edge technology with unmatched style and comfort. Standard 20” chrome-plated wheels, LED lightblade taillamps, and heated/cooled seats won’t save your life, but they do elevate the driving experience. And the simple value in that can’t be understated for a vehicle billed as the King of SUVs. And don’t worry, with a 420-hp, 6.2L V8, it drives like it deserves the crown.

If you have any questions about the availability of these features, or about the Cadillac lineup in general, please talk to one of our knowledgeable product experts.

Denali: The Peak of Professional Grade

Denali: The Peak of Professional Grade

Since 1999, the very best GMC vehicles have worn the name Denali. Named after the highest mountain in North America, Denali vehicles are the peak of luxury and performance. They’ve always included the most powerful engines and the finest interior materials. And for 2018, GMC’s best vehicles will also include the most sophisticated entertainment and safety technology.

Denali Luxury

Of course, luxury remains a top priority of every vehicle in the Denali lineup. GMC has carefully crafted the interior of each to ensure comfort and class. First-class materials like Java Burl poplar wood, aluminum, and fine leather set the tone. And the exterior reflects that tone. The signature, chrome Denali grille, LED signature lighting, and stunning wheel options ensure that your Denali truck or SUV is unmistakable on the road. But a Denali is about much more than just luxury.


Colour Head-Up Display: A Head-Up Display or HUD is a display projected onto the windshield of your vehicle. You can customise what information you want to see on the HUD and it appears above the dashboard in vivid colour. You can see speedometer, RPM, transmission position, external temperature, and current audio input. Obviously, having a HUD allows you to view important driving information without taking your eyes off of the road.

Wireless Charging: The days of fumbling with wires and finding the right adapter in your vehicle are gone. Denali vehicles come with standard Wireless Charging mats. Just place your compatible smartphone in the dock and you’ll be ready ready to go when you arrive at your destination.

Low Speed Forward Automatic Braking: Cameras and sensors at the front of your vehicle scan the road for potential obstacles. In the event of an imminent collision with an obstacle, the system can engage the brakes automatically to limit the severity of a collision without any input from the driver. When driving at very low speeds, your GMC vehicle can even prevent a collision entirely.

Bose Audio: Bose has a track record of creating some of the best audio systems for high fidelity sound reproduction. In every Denali vehicle you’ll find authentic Bose speakers positioned perfectly for studio quality sound. Behind the scenes, GMC has also included Bose’s highly regarded Active Noise Cancellation. The system emits negative waves that cancel the sound of the wind and road. And, with standard OnStar 4G LTE WiFi, connecting to your favourite songs and audiobooks is easier than ever.

Four Signs You Should Replace Your Brakes

When to replace brakes.

You shouldn’t be surprised to hear that your brakes are one of the most important systems in your vehicle. When you’re flying around in a steel box at 100km/hr, it’s nice to know that you’ll be able to stop. Relatively, brakes don’t require a great deal of maintenance. However, it’s important you perform the required maintenance in a timely fashion. Fortunately, brakes aren’t shy about letting you know when they need service. Here are four signs you should replace your brakes. 

Constant Screech

Do you hear a screeching sound when you brake? I mean, do you hear a screeching sound when you brake after you turn down the radio. It’s probably the brake pad wear indicator. The brake pad wear indicator creates an annoying screech noise on purpose so that you know when to replace your brake pads. If you suspect this is the problem, simply look at your brake pads (assuming you can see through the wheel spokes). Healthy brake pads are usually thicker than 3 to 5 mm.  

Morning Screech

However, if you only hear the screeching sound during the first few stops on a day when the road is wet or cold your brakes may be fine. Why? Well, your brake rotors are made of unfinished metal and can rust literally within hours. Brake rotors (or discs) are what your brake pads clamp against to stop your wheels. If the rotors have rust, it will be worn away during the course of the first few stops, and the screeching will stop.


If instead of a nice screech, you hear a grinding or growling sound, your brake pads may already be completely worn down. If you ignored the sound of screeching, your brake calipers may now be making direct contact with the rotors. That’s metal on metal. Now, with common sense, no one would allow their car’s brake pad to wear away completely. But a quick observation of modern politics reminds us common sense is a commodity in no great surplus. If your brake pads are worn away and you’ve continued to drive, you probably need to replace your brakes.


Obviously, some symptoms of brake wear are felt rather than heard. For example, the fact that it takes longer to stop over time is an indication that your brake pads are wearing down. More seriously, if you ever push the brake pedal all the way to the floor and the vehicle doesn’t stop, this probably suggests your brake fluid reservoir is low. Allowing your brake fluid to run dry is wildly dangerous. Brake fluid literally moves the different components in your brakes. Without it, you’re not stopping until air resistance, gravity, and static friction let you. If you notice you’re low on brake fluid, top up immediately!

How to Replace Your Brakes

Replacing brakes is a moderately difficult task for those with a little mechanical nous. You’ll need a jack, preferably hydraulic. Obviously, you’ll also need a need set of pads and/or rotors. But don’t worry. If replacing your brakes is beyond your qualifications as a mechanic, a professional shop can do the job quickly and easily. If you want efficient, expert service, bring your vehicle to Capital GMC Buick Cadillac. Relax in our modern customer lounge, or use our complimentary shuttle service, and your vehicle’s brakes will be restored to optimal function before you know it!

New Year’s Road Resolutions: Practice Safe Driving in 2018


I know, I know. This is yet another New Year’s resolution post. But it’s not my fault. If you don’t write hack New Year’s, Valentine’s day, and Christmas posts, you lose your membership to the International Bloggers Union (no, we don’t get health benefits). Plus, this is important. Making a resolution to practice safe driving makes the road a better place for everyone.

Following Distance

How many accidents would be avoided if everyone kept a safe driving distance between themselves and the cars in front of them? Thousands! And yet, if you drive anywhere, you can watch the traffic queue up bumper-to-bumper or watch the headlights of some kid in a Subaru WRX disappear beneath your rear view mirror because you aren’t exceeding the speed limit as significantly as he would like.

In ideal conditions you should leave two to three seconds between your vehicle and the one in front of you. In suboptimal conditions (75% of the time in Saskatchewan) you should increase that number to five or six. To help you adhere to your new resolution consider adding the Following Distance Indicator technology available on most new GM vehicles. It will let you know when you’re going too close for safety. Then again, if you can’t tell you’re too close to a car’s bumper with your naked eyes, then you probably shouldn’t be driving.

Put the Phone Away

Guess what? Using your phone while driving significantly and needlessly imperils you, pedestrians, and other drivers. Per CAA, drivers who text are 23 times more likely to crash, 27% of fatal crashes in BC are the result of distraction, and 26% of crashes involve phone use. Further, distracted driving is a factor in four million motor crashes in North America per year.

Nothing happening on your phone is important enough to justify endangering lives – especially not choosing the right Snapchat filter to convey your ennui. So, spare yourself the $280 ticket and four license demerits and put down your phone.

Turn Signals

A turn signal is a useful device. It indicates your intent to others so they can accommodate you on the road. If you signal for a lane change, it gives cars in your blind spot a chance to let you know they’re there, avoiding a potential collision. If you signal for a turn, vehicles travelling straight can move into a different lane or prepare to stop. In a utopia, the turn signal would be used early and astutely. Suburban Regina, if you hadn’t noticed through other means. Is not a utopia.

Around here (I expect the same is true everywhere), people do not use their turn signals early or astutely. They either use them after they’ve gotten into a turn lane (thanks for the heads up!) or while they’re in the middle of changing lanes. This behaviour is obviously dangerous and arises from simple laziness. More importantly, it is an insult to the memory of Oscar J. Simler, who invented the turn signal in 1929!
