Anti-Lock Brakes
 
Description: Today, virtually all cars come with ABS as standard equipment or as an option. The typical ABS system includes wheel-speed sensors, a hydraulic control unit, and an electronic control unit. When you apply the brake pedal, the electronic control unit monitors and compares the signals from the wheel-speed sensors. If the electronic control unit senses rapid deceleration (impending lock-up) at a given wheel, the electronic control unit commands the hydraulic control unit to reduce hydraulic pressure to that wheel. This type of pressure limiting is similar to pumping the brake pedal, only much faster. Some pick-up trucks and cargo vans have rear-wheel only ABS to handle different braking needs under different loading conditions. This type of ABS system controls only the rear wheels and limits pressure to both of them when either is about to lock. 
 
Purpose: ABS was designed to help you maintain directional control during emergency stops and when road conditions are poor. By maintaining control, you have better chances of avoiding a crash. ABS is especially useful on wet and slippery roads. You should never pump the brake pedal on a car with ABS, since the system itself “pumps” the brakes automatically. All you need to do is apply firm and continuous pressure to the brake pedal to activate ABS operation. When the ABS system operates, you may feel a pulsating sensation from the brake pedal. When ABS operation is no longer needed, the braking system reverts to conventional hydraulic operation without intervention from the ABS system.
 
Maintenance Tips/Suggestions: When turning the ignition switch to the on position, the amber BRAKE, ANTILOCK or ABS light on the instrument panel should glow momentarily, and then turn off. If the light stays on or flashes, or comes on while driving, it indicates a fault in the ABS system. Have your car’s ABS system inspected immediately by a professional technician to determine the source of the problem. Your owner’s manual may specify periodic flushing and filling of the brake hydraulic system, which should not be overlooked. This is a service best left to professional technicians, as many cars with ABS have specialized brake-bleeding procedures. Braking systems with ABS can also generate extremely high hydraulic pressures, which can be dangerous. Once again, consult a professional service technician if your car needs ABS or hydraulic system service.    

Bumpers

Description: Bumpers are located at the front and back of the vehicle and may be chrome, black, matched or coordinated with the rest of the vehicle's colours. Bumpers usually incorporate a plastic cover and lower panel, and a reinforcement bar. Bumpers on 1983 and newer cars are required to withstand a 2.5 mph impact. This safety standard does not apply to vans, pickups and SUVs.    
   
Purpose: Bumpers used to serve a largely ornamental function and were almost exclusively chrome. Today, automobile bumpers complement vehicle appearance, but are also designed to minimize damage from low-speed collisions by absorbing crash energy.    

Maintenance Tips/Suggestions: Your car's bumpers are not designed to absorb unlimited low speed collisions. During an impact, the energy absorbing material will likely be damaged and need replacement. Just because the bumper looks fine on the outside doesn't mean that it still can absorb additional impacts. If your car is involved in a collision -- no matter how minor -- have the bumper damage evaluated by a qualified collision repair professional.

Safety Glass

Description: Safety glass is a critical safety element of your car. The windshield is made of laminated safety glass, made by sandwiching a sheet of plastic between two or more layers of glass. The side windows are made of tempered safety glass, which is made by heating, then a rapid cooling process.       
 
Purpose: Safety glass performs several crucial tasks:
  • Greatly reduces the size and number of flying glass pieces during an accident, lessening the chance of injury to those inside the car.
  • When the glass breaks, it results in small pebble-like pieces rather than the jagged, sharp pieces from conventional glass.
  • When used in a windshield, safety glass helps keeps occupants inside the car during an accident and also serves as a deflection panel when the passenger side airbag deploys.
  • Because of its high strength, it can provide structural support for the roof in the event of a rollover accident.      
Maintenance Tips/Suggestions: Keep the glass clean at all times. Insects and other debris can be removed with the use of a "bug sponge" and a proper cleaner, but be careful not to use strong abrasives that may scratch the glass.
 
Make sure that the windshield washer solvent reservoir is full so you can use your windshield wipers to clear your view when driving. This is critical during the winter months. Inspect your wiper blades frequently. If worn or damaged, bad wipers can damage the windshield. To help improve visibility further, consider a dirt and water repellent that you apply directly to the windshield.
 
Minor windshield damage such as chips and cracks can be repaired using methods now accepted by insurance companies. If complete windshield replacement is needed, it must be installed properly to yield all its safety capabilities. If you're in doubt about the condition of any glass on your car, consult a qualified automotive glass professional.   
 

Horn

Description: The horn system usually includes a horn switch, horn or pair of horns, fuse, relay and related wiring.       
 
Purpose: The horn is used to alert other drivers of sudden situations. The horn system is also used as a signalling device for anti-theft systems.   
   
Maintenance Tips/Suggestions: The horn is an important safety device and should be checked out immediately if it doesn't work. First, check the horn fuse (refer to your car's owner's manual for the fuse locations and assignments) and replace it if needed. If the fuse is OK, check the connection at the horn to make sure it's secure. If the connection at the horn is OK, make sure the horn relay is located securely in its socket (this location is also specified in the owner's manual). If everything seems OK and the horn still doesn't work, have the system checked by a professional technician. 
  

Lights

Description: Your car's lighting system consists of several different systems integrated together: Headlights (high and low beams), fog lights (optional), parking, tail and marker lights, instrumentation lighting, turn signals, emergency flashers, stoplights, backup lights and interior lights.        
 
Purpose: The lighting system provides nighttime visibility under different driving conditions, signals and alerts other drivers, and supplies light for viewing instruments and the interior.      
 
Maintenance Tips/Suggestions: During normal driving, you may not notice a light that isn't working. That's why it's best to have your car's lights inspected at every oil change. Most often, the cause of a faulty light is a bad bulb. If a whole portion of the lighting circuit doesn't work, such as the taillights, check the fuses. Refer to your car's owner's manual for recommended bulb and fuse types, their locations and for information on how to change them. Most bulbs and fuses on today's cars are easy to change.
 
If you're changing a halogen headlight bulb, do not touch the bulb with your bare hands. Oil from your skin can cause the bulb to fail prematurely. A turn signal that flashes in one direction, but not in the other direction, usually means there's a bad bulb on the side that does not flash. If the bulbs and fuses seem OK, but the lighting problem persists, have the lighting system looked at by a qualified service professional.  
 

Mirrors

Description: Your car's lighting system consists of several different systems integrated together: Headlights (high and low beams), fog lights (optional), parking, tail and marker lights, instrumentation lighting, turn signals, emergency flashers, stoplights, backup lights and interior lights.        
 
Purpose: The lighting system provides night time visibility under different driving conditions, signals and alerts other drivers, and supplies light for viewing instruments and the interior.

Seat Belts

Description: High-tensile strength belts and harnesses, connected to high-strength buckles, make up today's seat belts. Once an option in the 1950s, seat belts are one of the most important standard safety features of your car.  
      
Purpose: Seat belts have been statistically proven at preventing injuries and saving lives. Seat belts save over hundreds of lives each year. Safety belts and harnesses play the primary role in passenger protection. They provide protection during accidents from all directions, security during a rollover and proper passenger positioning when an air bag deploys. They can also prevent the passenger from being hurled forward during mild front collisions.    
Maintenance Tips/Suggestions: Keep your car's seat belts in good operating condition. Replace any belt that is cut, frayed or shows signs of weakness. Make sure that the buckles engage completely and don’t separate when pulled. Seat belts sometimes have defects that are covered under a recall from the manufacturer. To see if your vehicle is covered, visit the Transport Canada website http://www.tc.gc.ca/roadsafety/recalls/recintro_e.htm.
 

Air Bag

Description: Some cars have just an airbag on the driver's side; others have both passenger and driver's side airbags. During a front collision of sufficient force, impact sensors close. This triggers an electrical signal that travels to the air bag module. Upon receipt of this signal, current arcs across both pins of an igniter and starts a chemical chain reaction. This arc ignites a canister of gas that ignites sodium azide pellets. The pellets burn rapidly and change to nitrogen gas. The rapid build-up of nitrogen fills the bag quickly. The rapid expansion of the air bag tears the steering wheel cover open at specific locations. The bag reaches full deployment shortly thereafter.       
 
Purpose: During a severe frontal collision, the air bag deploys and absorbs the forward force of the driver's or passenger's upper body as it spreads out over the large surface area of the bag. Air bags and safety belts make a team. Air bags don't replace belts. They only supplement them during severe front collisions.     
 

Side Impact Air Bags

Description: Side-Impact airbags come in two different types: torso protecting and head/torso protecting. Of the car models built in 2003, 40 percent offered head-protecting side airbags (24 percent standard equipment, 16 percent optional equipment). An even larger number of 2004 model year passenger vehicles are offering side airbags with head protection (27 percent standard equipment, 21 percent optional equipment).      
 
Purpose: Side-impact airbags provide supplemental protection during side impacts. Some types provide protection for just the torso, or for both the head and torso. According to data from the Insurance Institute for Highway Safety in the United States, side-impact airbags have reduced deaths among passenger car drivers involved in driver-side collisions by about 45 percent when the side airbag included head protection and by 11 percent when the side airbag was designed to protect only the torso. 
 
Maintenance Tips/Suggestions: Side-impact airbags do not require any periodic maintenance. However, to ensure that the system is operating properly, make sure that the airbag indicator light works exactly as described in the owner's manual. With the ignition in the on position, the light should come on momentarily and then go out. If the light stays on or comes on while driving, have the system checked by a professional service technician. Also, air bags sometimes have defects that are covered under a recall from the manufacturer. To see if your vehicle is covered, visit the Transport Canada website.

Air Bag Switch

Description: An air bag on-off switch overrides the automatic deployment function of vehicle airbags and can be installed for the driver, passenger, or both. To operate the switch, a special key is required to reduce the chances of misuse. When the air bag is turned off, a light appears stating DRIVER AIR BAG OFF or PASSENGER AIR BAG OFF. The air bag remains deactivated until the key is used to turn the system back on.
 
Purpose: An air bag on-off switch allows an air bag to be turned off for special circumstances. Some scenarios where air bag deployments may be risky include:
When absolutely essential to transport infants riding in rear-facing infant seats in the front passenger seat.
When absolutely essential to transport children ages 1 to 12 in the front passenger seat.
When drivers cannot change their customary driving position and keep 25 centimetres between the centre of the steering wheel and the centre of their breastbone.
 
For people whose doctors claim that because of a medical condition, an air bag poses a special risk that exceeds the risk of hitting their head, neck or chest in a crash when the air bag is turned off.
 
Maintenance Tips/Suggestions: Deactivating your air bag will not benefit you or other users of your vehicle. Instead, it will increase the risk that you and the other users will suffer a head, neck or chest injury by violently striking the steering wheel or dashboard in a moderate to severe crash. The installation and use of an air bag switch is only allowed under the above conditions and should be performed by a trained service professional. Not all repair facilities install air bag switches.

Safety Inspections


Description: Safety inspections consist of a series of safety-related checks for various systems and areas of the vehicle. For example, some common checks include glass, horn, tires, wipers, lights, turn signals, brakes, mirrors, steering, suspension, and restraint systems. Some Canadian provinces require safety inspections at different times, such as when selling your vehicles. 
 
Purpose:  Many other countries often adopt safety inspections as a means of regulating improved safety for motorists. Research shows that jurisdictions with annual safety inspection programs have accident rates that are 20 percent lower than in jurisdictions without safety inspections. Safety inspections represent a good opportunity to have minor problems corrected before they become major problems or hazards.    
  
Maintenance Tips/Suggestions: If you live in an area that requires a safety inspection, welcome it as an opportunity to have your car looked over thoroughly. There's more at stake here than just safety; an inspection can also detect problems that could cause major breakdown headaches in the near future. Plan your inspection into your schedule at a time when the inspection facility isn't backed up with other work. This often happens at the end of the month when everyone suddenly rushes at the last minute to schedule an inspection. Planning ahead gives you time to make better choices about different repairs or services that may be needed as determined during the inspection.
