High temperatures in the summer can be great for a day at the beach, but these scorching hot temperatures and long summer road trips can be tough on your BMW. We’ve compiled 8 safety tips to keep your BMW running as smoothly as possible throughout the summer because, well, the summer heat cannot be avoided entirely! Read and follow carefully to ensure that you avoid any issues, or worse, a total breakdown.


1. Check Your Tires

Before you head out on a summer adventure, it’s crucial to make sure all tires are inflated to the pressure recommended for your BMW. Driving with over-inflated, under-inflated, worn down, damaged or misaligned tires can be very dangerous- especially in the summer season.

Did you know that tire pressure increases as the outside air temperature rises? The same tires that were at 35 PSI on a cool February evening could be full of pressure on a hot July day (like today). In some instances, the increase in tire pressure is substantial enough to blow out the tire!

Always ensure to inspect your tire pressure before going for a drive. It’s also worthwhile to inspect tread depth and overall condition as well. While analyzing your tires’ tread, pay careful attention to an uneven wear pattern. If the tire is more worn on one side, you may need a wheel alignment.

Besides being a huge safety concern, over-inflated, under-inflated and misaligned tires can lower your car’s fuel economy.

2. Check Your Battery (and Make Sure it’s Clean)

Excessive heat is known to shorten the life of a battery and it does so in two common ways:

1. Speeds up the chemical reaction in the battery to the point where the battery is overcharged

2. Evaporates the internal battery fluid

To avoid battery failure this summer, it’s good to err on the side of caution and regularly maintain your battery. Keeping your battery clean is an excellent way to extend its useful life. The first thing to do is to inspect terminals, cables and the battery top for dirt, oil, corrosion or build up. Did you know that heavy dirt can be a conductor? It drains battery power. If there’s corrosion on the battery terminals, it inhibits the flow of electricity.

What should you do about this? Try regularly wiping the battery top and terminals- making sure that the battery is strapped down tightly and all connections are securely fitted. Should your battery not hold a charge anymore, bring it to the BMW Markham Service Department and our BMW Certified Service Technicians will help you make the most of the battery, or at the very least, help you replace the battery entirely.

Keeping your battery clean can not only help your battery last longer but it can also save you quite a bit of money! Don’t let prevention be an afterthought, take care of your battery now and not later. Summer heat actually accelerates the build up of corrosion- so be very meticulous upon inspecting your battery and take these helpful tips to heart!

3. Maintain Your Air Conditioning

Ever had your air conditioner break down on you? Yeah, it’s awful. Your Air conditioner is debatably the most important summer driving essential. You’re going to want to pay attention to these A/C maintenance tips if you don’t want to sweat this summer.

During the summer, your air conditioner encounters problems for two common reasons:

1. It works extra hard to prevent the engine (and all vehicle passengers) from overheating.

2. Bacteria buildup gets trapped in the ventilators during the colder seasons- resulting in foul odours.

So, what can you do to prevent your air conditioner from malfunctioning or spewing a bunch of foul odours out of the vents on a hot summer day?

One trick is to continuously use your air conditioning system. The continuous use of your air conditioning actually helps prevent the build-up of mold and bacteria inside the micro-filter. Although this is not fool proof or guaranteed, ensuring that the air vents are constantly circulating air is an easy, cost-effective way of preventing bacteria buildup.

If musty odours have already started to flow out of your ventilators or if the temperature does not reach your desired level of cool, simply making sure the air vents are constantly flowing isn’t enough. To keep your cooling system operating at its peak, your air conditioning should be maintained and checked regularly. Remember, a cooling system that is operating at less than its peak performance is more likely to fail during the summer months. At BMW Markham, we can help you identify and fix the air conditioning problems before it’s too late. Come in for an A/C inspection today by calling us at 905-477-0822 or emailing us at

bmw brakes

4. Inspect Your Brakes

It is absolutely necessary to check on your brakes before you leave on a lengthy drive. It’s arguably one of the most important safety features in your vehicle! Worn down or faulty brakes can put you, your family and your friends at risk.

If your brake pedal becomes very resistant to push down or if there are loud grinding sounds coming from the brakes, you should definitely bring your BMW in for an inspection. Ensure that the lining on your brake pad isn’t too worn down as well.

BMW coolant

5. Top Up Fluids

Low coolant levels, brittle hoses, and loose or damaged belts can cause your car to overheat and break down. Avoid overheating at the roadside by checking under your hood and topping up the coolant. Remember to top up your windshield washer fluid too!

If you see a puddle of coolant under your vehicle after it’s been sitting at your parking spot for a couple hours, then you have a coolant leak. It’s essential to have your system checked right away when this happens- you don’t want your engine to overheat while stuck in a summer traffic jam!

air filter

6. Change the Air Filter

Winter is known to clog air filters with lots of debris. Luckily, your BMW will tell you when the filter needs to be changed. Replacing a dirty air filter will safeguard the performance and longevity of your engine. Consider replacing the interior filter as well to ensure everyone is breathing clean air into their lungs while in the vehicle.

If we haven’t convinced you to change your air filter yet…did you know that a clogged air filter can lower your fuel efficiency? Yes, that’s right- it’s really worth changing at regular intervals. Depending on when you purchased your BMW, your air filter may still be covered under warranty. To find out, simply give us a call at 905-477-2212. We would be happy to help get you a fresh Original BMW Air Filter.

bmw oil

7. Change Your Oil Regularly

Most of us do a lot of driving during the summer. Driving for lengthy distances in hot temperatures can overheat the engine, so you must ensure that you’ve changed your oil before piling your friends into your car and going on that road trip you’ve been planning for the entire span of winter.

Depending on the model of your BMW, your vehicle will either have a CBS or SII system- both of which will alert you when your BMW is due for an oil change with a dashboard symbol.

Call us at 905-477-0822 to book an oil change appointment before you embark on your next summer adventure!
