Steering
Power Steering
If power steering assist is lost because the engine stopsor the system is not functioning, the vehicle can besteered but it will take more effort.
Magnetic Speed Variable Assist
Steering System
This system continuously adjusts the effort felt whensteering at all vehicle speeds. It provides easewhen 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 tiresand the road surface, the angle at which the curve isbanked, and vehicle speed. While in a curve, speed isthe one factor that can be controlled.
If there is a need to reduce speed, do it before enteringthe curve, while the front wheels are straight.
Try to adjust the speed so you can drive through thecurve. Maintain a reasonable, steady speed. Waitto accelerate until out of the curve, and then accelerategently into the straightaway.
Steering in Emergencies
There are times when steering can be more effectivethan braking. For example, you come over a hill and finda truck stopped in your lane, or a car suddenly pullsout from nowhere, or a child darts out from betweenparked cars and stops right in front of you. Theseproblems can be avoided by braking — if you can stopin time. But sometimes you cannot stop in timebecause there is no room. That is the time for evasiveaction — steering around the problem.
The vehicle can perform very well in emergencies likethese. First apply the brakes. SeeBraking on page 5-3.It is better to remove as much speed as possiblefrom a collision. Then steer around the problem, to theleft or right depending on the space available.
