Your vehicle is a complex machine that exposes you and your occupants to a variety of hazards – that’s why vehicle safety is not a joking matter.  In fact, your vehicle contains many safety features and components that are working silently to protect you all the time! In this blog, we examine the function of five important vehicle safety features, the signs and symptoms of possible failure, and ways to keep them maintained.

Feature	Function	Signs and Symptoms	Maintenance
Braking System	The braking system is an organization of parts designed to slow or stop your vehicle while in motion. When you depress the brake pedal, the braking system releases brake fluid into a line to release pressure on calipers that sit on either side of rotors. These calipers clamp down on the rotors with pads to stop the wheels from moving. Braking system parts include:  Brake fluid  Rotors  Calipers  Brake pads	Your vehicle’s braking system is exposed to heat, dirt, water, and friction while in use. These elements lead to eventual wear and corrosion. Things to look for in failing brakes include:  Squealing, vibration, or screeching during braking  Soft or “airy” sensation when depressing the brake pedal  Brake fluid leaks  Brake light indicator light	Your braking system should be checked regularly for wear and tear. A service professional will inspect the brad pads and rotors for wear and grooves. Brake fluid should be replaced every few years as it can build up dirt, water, and air. Bleeding brakes lines will help remove trapped air.
Suspension System	The suspension system helps your vehicle maintain a smooth and comfortable ride. It responds directly to the bumps and friction of the road to absorb that negative energy. Suspension system parts include:  The steering system  Tires  Shock absorbers  Springs or struts  Other components	Your vehicle’s suspension system is impacted by various road conditions such as holes, bumps, rough surfaces, and road salt. Suspensions can handle a lot of stress but can deteriorate from rough conditions, heat, or poor driving technique. Things to look for in a failing suspension include:  Uneven tire wear  Pulling to one side during driving  Bouncing or squeaking sounds  Front nose dives down during braking  Leaks	You can extend your suspension through:  Periodic tire rotations and wheel alignment  Maintaining proper tire air pressure  Focusing on the road surfaces and improving driving habits
Tire Pressure Monitoring System	If you own a vehicle that was manufactured since 2008, it has TPMS. TPMS is a system of sensors on the wheels that measures real-time air pressure of your tires. Tire pressure can change as a result of temperature, wear, and foreign objects that might deflate or blow out the tire.	TPMS problems are usually the result of faulty sensors or weak sensor batteries. Things to look for in a failing TPMS include:  Warning light will not go out (might be as simple as a reset to the TPMS)  Tire pressure (taken by physical gauge) differs from displayed pressure  TPMS does not illuminate when air pressure is low	Your best recourse for TPMS is to have the sensors checked and replaced. While a failing TPMS will not affect driving ability, it is an important issue to address promptly with a service professional, especially if you do not check your tire pressure manually.
Electronic Stability Control	ESC is designed to correct a vehicle that may have slipped or lost traction with the road. For example, driving on some wet conditions may cause the tires to spin out and the vehicle to tailspin. In that type of situation, ESC engages the braking system to self-correct the vehicle.	The more common problems you may have with ESC involve the sensors or wiring. ESC is controlled by a series of sensors that constantly monitor for irregularities. Things to look for in a failing ESC include:  ESC warning light does not illuminate in certain driving conditions  ESC warning light stays lit	If you suspect there is an issue with your vehicle’s ESC, have it inspected by a service professional. They will test the sensors and make sure that it is operating effectively.
Vehicle Airbags	Airbags have been in US cars for many years, and have improved over time. Airbags are designed to deploy a cushion restraint for vehicle occupants (ie. Inflated bag), during a collision. Proper deployment ensures that occupants are protected from impacting the steering wheel, seats, or the dashboard. Side airbags protect against metal impacts from doors.	Unfortunately, airbags cannot be tested. The only way to know they are operating effectively, is to deploy them during a vehicle collision. If you have any airbag warning lights illuminate in your vehicle, check with your owner’s manual.	Auto manufacturers are required to recall and repair/replace any airbag issues. There are websites to check your vehicle VIN number to determine if your vehicle has an active airbag recall. If you are concerned, contact a service professional or your vehicle manufacturer.

Safety is an important factor in your overall enjoyment of your vehicle.  Make sure to keep your vehicle in top shape by listening and looking for signs when critical safety systems might be failing.  If you have concerns or questions, make an appointment today with your Geller’s Automotive service professional.
