9-4 Driving and Operating
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 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.
If there is a need to reduce speed,
do it before entering the curve, while
the front wheels are straight.
Try to adjust the speed so you can
drive through the curve. Maintain a
reasonable, steady speed. Wait to
accelerate until out of the curve,
and then accelerate gently into
the straightaway.
