Control of a Vehicle

You have three systems that make your vehicle go

where you want it to go. They are the brakes, the

steering, and the accelerator. All three systems

have to do their work at the places where the tires

meet the road.

Sometimes, as when you are driving on snow or ice, it is

easy to ask more of those control systems than the tires

and road can provide. That means you can lose control of

your vehicle. See Enhanced Traction System (ETS) on

page 4-9.

Adding non-GM accessories can affect your vehicle’s

performance. See Accessories and Modiﬁcations

on page 5-3.

Braking

See Brake System Warning Light on page 3-29.

Braking action involves perception time and

reaction time.

First, you have to decide to push on the brake pedal.

That is perception time. Then you have to bring up your

foot and do it. That is reaction time.

Average reaction time is about three-fourths of a

second. But that is only an average. It might be less

with one driver and as long as two or three seconds or

more with another. Age, physical condition, alertness,

coordination, and eyesight all play a part. So do alcohol,

drugs, and frustration. But even in three-fourths of a

second, a vehicle moving at 60 mph (100 km/h) travels

66 feet (20 m). That could be a lot of distance in an

emergency, so keeping enough space between

your vehicle and others is important.
