Anti-Lock Braking System
Helps maintain control by preventing any of the wheels from locking while applying a hard brake. The pedal vibrates when pushed, but steering control can be maintained with the rolling traction. Computer-controlled braking system that keeps the wheels from locking when the driver brakes hard. It allows for steering and braking actions to occur at the same time.
Properly balanced tires are important for driving comfort and long tire life. Unbalanced tires can cause vibration, resulting in driver fatigue, premature tire wear and unnecessary wear to your vehicle’s suspension. Tires should be balanced when they are mounted on wheels for the first time or when they are remounted after repair. Tires should be rebalanced at the first sign of vibration or “shimmy.”

Your tires are the only thing keeping your car on the road and driving safely. A tire’s footprint, or the area that is actually in contact with the road, is quite small. This tiny tire footprint is what creates the traction that allows your car to accelerate, decelerate, and turn. If these contact points are hampered by poor tread or under inflation, your ability to steer, start, and stop can be adversely affected.
Tire rotation is the practice of swapping the front tires of a car with the back tires at regular intervals. The basic idea of tire rotation is to extend the life of the tires by allowing more even tread wear.

Some tire stores even include a basic tire rotation as part of their service contract.
