The manufacturer placed the tibia pad between the floor mat and the vehicle floor. The polystyrene resin product absorbs the impacts on the legs of the driver and passengers. Some tibia pads in high-performance cars have noise-absorbing properties.

Floor Carpets

Like the foot mats in our homes, the floor carpets collect the dirt on our shoes for easier disposal. This prevents an unhygienic environment that may lead to a foul smell. With good floor carpets, you can prevent the accumulation of water and dirt in the vehicle interiors.

This differs from the normal mechanic toolbox that you can find in a garage. It is a molded plastic compartment in the luggage area that has a small space. In most vehicles, it contains the jack and wheel lug spanner.

Tonneau Cover

A tonneau cover will save you some bucks from theft, damaged/lost cargo, and poor gas mileage. It also protects the truck bed and prevents severe system damages that will need expensive repairs.

Seat Fabrics

Luggage Trim

Gear Selector

The gear selector is known as a stick shift in manual transmissions. It is what the driver uses to engage the gears. In manual transmissions, the driver had to shift the gear lever into each gear.

Whereas, in automatic transmissions, the tranny unit and the PCM changes the gear range depending on how the driver accelerates or decelerates.

The gear lever connects to the transmission directly in manual cars. But automatic transmissions have a connecting rod that connects the gear selector to the transmission unit.

Poor window or door lock controls

A power window is an automatic control lock that powers all the windows. It is used to lock and unlock the doors. And it is on the driver’s door. This feature is available on newer cars.

Temperature Gauge

The temperature gauge works in harmony with your vehicle temp sensor to measure the temperature of the engine coolant and projects it on the dashboard. This prevents the engine from overheating.

Rear-view Mirror

The rearview mirror is a part of a car inside the cabin that is mounted on the windshield. It allows the driver to see behind him.

The rear mirrors have accompanying side mirrors that allow the driver to see the coming vehicles. Bicycles, motorcycles, and some trucks use only side mirrors.

It connects to the rear wheels via a brake cable. Motorists mostly use it when parking a vehicle. It prevents the car from moving forward or backward.

Air Vents

Newer cars have air conditioning systems. The function of this system is to send cool air into the cabin during hot weather conditions according to the driver’s requirement.

The HVAC system either continuously recirculates the air inside the cabin to cool it, or sends cooled ambient air into the cabin. Whichever way the AC system works, it sends the cooled air into the cabin through the air vents or air ducts.

Audio system

When naming parts of a car and describing their functions, you don’t have to exclude the audio system. It is one of the most important car parts of a car. It provides information and entertainment. The driver can play songs when cruising on the highway.

In the 1950s, vehicles had only AM radios. However, as the automotive industry evolves, manufacturers convert AM radio into record players, CD players, DVD players, 8-track cassette players, cassette players, and Blu-ray players. Modern car audio systems now feature navigational systems and smartphone controllers, such as Android and CarPlay Auto.

Glove or Storage Box

The glove box is a plastic compartment built on the passenger side dashboard. The manufacturers built it to enable the driver to store various things like photocopied car papers, owner’s booklet, and many other things.

Beverage or Cupholder

The beverage or cup holder serves as the table in restaurants when traveling. It is highly sustainable, durable, and easy to operate. It is used to store important things like food and beverages when driving.

Many trucks, ships, buses, cars, trains, and airplanes have cup holders. They are also available in some passenger buses.

The fuel gauge is a vital component for every driver. It keeps the driver updated so that he won’t run out of gas when driving.


The speedometer, also known as a speed meter, is an important component that projects the speed at which a vehicle travels on the dashboard. It is mounted on the vehicle dashboard.

The speed meter has several names on other vehicles and several means of detecting speed. It is called a pit log in boats and an airspeed indicator in airplanes.

Brake Pedal

Manufacturers place the brake pedal on the floor of the driver’s seat next to the gas pedal. It connects to the brakes in the wheels, and it’s used in controlling the brakes.

A driver will have to depress the brake pedal to slow down or stop a moving vehicle. Like the gas pedal, the driver applies the brake pedal with his right foot.

Gas Pedal

The gas pedal, also known as the accelerator pedal, is located close to the brake pedal beneath the dashboard on the driver’s side.  It is used to feed gas to the engine to increase the speed of a car.

As the car is moving, slowly depress the gas pedal to increase the speed. Always maintain the speed you can control.

Clutch Pedal

This component is only seen in manual transmission cars. It is installed next to the brake pedal. As the driver depresses the clutch pedal, it disconnects the engine from the transmission, ending engine power transfer to the transmission.

As you remove your foot from it, it permits the power transfer to continue. A driver has to depress it when changing gears on manual transmissions.


The airbag is one of the most important safety features in car interiors. It comprises bags that can inflate and deflate in case of collisions. The airbags have impact sensors, inflatable modules, airbag cushions, and flexible fabrics. 

The main purpose of the airbag is to prevent the passenger and the driver from flipping out of the car in case of a collision. It also minimizes the injury the passengers or driver may sustain. 

Steering Wheel

A steering wheel is a wheel on the driver’s seat that is used to control the movement of a vehicle. The steering wheel is also called the driving wheel or handheld wheel. 

A steering wheel connects to the rack and pinion, which has a direct connection with the front wheels. It is used to steer the wheels. The driver controls the steering wheel manually.

A steering wheel can either be a mechanical power steering system or an electric power steering system.

The steering wheel contains a horn contact unit that makes a loud audible noise when pressed to notify other vehicles and pedestrians of an oncoming vehicle. It also has other features like volume buttons, cruise control buttons, and paddle shifters.

Paddle Shifters

Paddle shifters allow the driver to change gears while holding the steering wheels without having to shift the gear lever. They are the switches behind the steering wheels that make gear shifting safer and quicker. They are common in racing and high-performance cars.
