9-4 Driving and Operating

But even in three‐fourths of a

second, a vehicle moving at

100 km/h (60 mph) travels 20 m

(66 ft). That could be a lot of

distance in an emergency, so

keeping enough space between the

vehicle and others is important.

And, of course, actual stopping

distances vary greatly with the

surface of the road, whether it is

pavement or gravel; the condition

of the road, whether it is wet, dry,

or icy; tire tread; the condition of the

brakes; the weight of the vehicle;

and the amount of brake force

applied.

Avoid needless heavy

braking. Some people drive in

spurts — heavy acceleration

followed by heavy braking — rather

than keeping pace with traffic. This

is a mistake. The brakes might not

have time to cool between hard

stops. The brakes will wear out

much faster with a lot of heavy

braking. Keeping pace with the

traffic and allowing realistic following

distances eliminates a lot of

unnecessary braking. That means

better braking and longer brake life.

If the engine ever stops while the

vehicle is being driven, brake

normally but do not pump the

brakes. If the brakes are pumped,

the pedal could get harder to push

down. If the engine stops, there will

still be some power brake assist but

it will be used when the brake is

applied. Once the power assist is

used up, it can take longer to stop

and the brake pedal will be harder

to push.

Adding non‐dealer/non‐retailer

accessories can affect vehicle

performance. See Accessories and

Modifications on page 10‑3.

Steering

Power Steering

If power steering assist is lost

because the engine stops or the

power steering system is not

functioning, the vehicle can be

steered but it will take more effort.

Variable Effort Steering

The vehicle has a steering system

that continuously adjusts the effort

felt when steering at all vehicle

speeds. It provides ease when

parking, yet a firm, solid feel at

highway speeds.

Steering Tips

It is important to take curves at a

reasonable speed.

Traction in a curve depends on the

condition of the tires and the road

surface, the angle at which the

curve is banked, and vehicle speed.

While in a curve, speed is the one

factor that can be controlled.
