Parking Light
installed near the headlights to help ensure that your car can be seen by other drivers. Some vehicles also have daytime running lights to increase visibility in daylight.
Taillight
illuminate when your headlights are on, and emit a brighter light when you press the brake pedal. They show other drivers the location of your car and alert them when you're braking.
Steering Column
includes the steering wheel, horn, ignition switch, wiper lever, and multifunction lever. In many cars, you can adjust the wheel to a safe, comfortable height.
turn signal
to signal right or left, push multifunction lever up or down, respectively. When clicked in place, the signal will blink until the turn is complete. Push gently to flash a signal briefly.
Headlights
activate by turning the knob on the multifunction lever, and switch between low- and high-beams by pushing the lever towards you or away from you.
Steering Wheel Controls
operate other vehicle features, such as cruise control, climate settings, the stereo system, or an integrated telephone system.
Multifunction Lever
Usually found on the left side of the steering column, used to activate turn signals and various vehicle lights, including low-beams, high-beams, parking lights, and fog lights.
Windshield Wiper Lever
usually found on the right of the steering column. Turn the end to set the speed of your wipers. You can also use it to spray washer fluid to clean the windshield
Warning Lights
show signs of problems with essential vehicle components, including the engine, battery, and brakes.
Temperature Gauge
indicates the engine temperature. When the engine overheats, the indicator will enter the Hot (H) zone and a warning light will activate. Never drive with an overheated engine.
Tachometer
indicates how fast the engine is moving in revolutions per minute (RPM). When in the red zone, the engine is moving too fast and may become damaged.
Gear Display
determines which gear is currently selected.
Speedometer
indicates the speed of your vehicle in miles and kilometers per hour (MPH/KPH).
Odometer
displays how many miles your vehicle has travelled since it was built
trip odometer
can be reset to zero manually so you can calculate trip mileage and fuel consumption.
Active System Lights
inform you about the status of important vehicle components, including the hood, doors, headlights, and front safety belts
Fuel Guage
indicates the amount of fuel in the gas tank. Your fuel tank should always be at least 25% full
Clutch Pedal
It is located to the left of the brakes, and must be pressed with your left foot when changing gears. In cars with automatic transmissions, a foot rest may be found in this location instead.
Dipstick
Determines the amount of motor oil in your car at the bottom of the gauge. Motor oil is used to lubricate the engine.
Motor Oil Cap
Remove when you need to change your car's motor oil. You should change your motor oil every three months or 3,000 miles, or whenever the oil level falls below the recommended level.
Radiator Cap
access the radiator directly to check the level of coolant in the radiator and flush it when necessary. Never try to remove while the car is still hot.
Engine Coolant
Check the reservoir to make sure that there is enough to keep your car from overheating. Should be flushed and replaced every 24 months, or 30,000 miles.
Battery
powers important electrical systems, including the ignition.
instrument panel
The area of the dashboard behind the steering wheel. Includes:
The speedometer
The fuel gauge
The odometer
The trip odometer
The tachometer
The temperature gauge
what do you do to cool down you engine?
You can attempt to get rid of the heat in your engine by stopping in a safe place, shifting to neutral, depressing the accelerator pedal to rev the engine slightly, turning off the air conditioning, and setting the heater as high as possible.
yellow indicator lights
provide warnings about potentially problematic situations with your car
red indicator lights
indicate that it is dangerous to continue driving and you should pull over and stop your car immediately
how do you work conventional brakes?
When stopping suddenly or responding to brake failure, drivers with conventional brakes must apply a pumping action for the brakes to work.
how do you work ABS breaks?
a driver with anti-lock brakes needs only to push down hard on the pedal to stop abruptly
dead pedal
At the far left of the area beneath the steering column, there is usually a raised foot rest where you should place your left foot while you drive.
P (Park)
In this position, the transmission is locked to prevent rolling.
R (Reverse)
In this position, the wheels spin backwards to allow you to back up your car. The white reverse lights on the back of your car will be activated.
N (Neutral)
In this position, the engine is disconnected from the drive wheels and the car can and will roll.
D (Drive)
This is the automatic forward gear. In most traffic conditions, including situations when you must stop frequently, the transmission should be set to this gear.
1 (First Gear)
Use this gear when exiting a stopped position and driving up to 10 to 15 mph.
2 (Second Gear)
Use this gear when driving up to 20 mph, or when climbing a steep hill or approaching a curve or turn.
3 (Third Gear)
On a three-speed transmission, use this gear for all speeds above 25 mph. On transmissions with more gears, use this gear for speeds between 20 and 40 mph.
Four-wheel drive
provides power to all four wheels to allow the driver more control, especially on uneven and low-traction surfaces.
cruise control
the driver is able to continue driving at the same speed without his or her foot upon the accelerator pedal. generally only works for speeds over 30 mph.
active restraints
Restraints that the user is responsible for engaging
passive restraints.
Restraints such as air bags, safety glass, and padded dashboards, sun visors, and head restraints that work regardless of the user's actions
Crumple zones
Front ends and trunks are designed to crush on impact, while many bumpers are now produced to absorb minor impacts without damage, so that the passenger compartment remains intact.
Side impact reinforcement
Stronger steel beams are installed inside the doors to protect occupants from side impacts.
Roof crush reinforcement
The design of the roof has been improved to make it more resistant to being crushed.
Laminated, or "shatter-resistant", windshields
A plastic sheet between layers of windshield glass keeps the glass bonded when broken to protect occupants from flying glass shards
Tempered side windows
When broken, the side windows will shatter into small cubes rather than jagged shards.
Collapsible steering columns
Designed to telescope in on itself in a collision, the collapsible steering column keeps the driver from being impaled.
Antilock Braking Systems (ABS)
apply a consistent pumping action to the brakes and detect if a wheel is about to lock.
Traction Control Systems (TCS)
make sure that individual tires don't lose traction with the road and begin to spin so that drivers can maintain control on different surfaces.
Active Yaw Control Systems (AYC)
monitor the dynamic state of the vehicle and apply the brakes to individual wheels to make sure drivers don't begin to rotate around the vertical axis (due to oversteering or understeering).
Suspension Stability Systems
detect driving conditions and raise or lower the vehicle's wheels for a smoother and more level ride.
Active Steering Control Systems
detect where the driver is intending to travel and make adjustments automatically to facilitate steering and improve control.
