Power Steering System
The power steering system includes the power steer-
ing gear, hydraulic hoses, power steering pump, res-
ervoir, steering wheel and column, and other compo-
nents.
The power steering pump, driven by the engine, pro-
vides the power assist for the steering system. If the
engine is not running, there is no power assist.
WARNING
Driving the vehicle without the power-assist fea-
ture of the steering system requires much greater
effort, especially in sharp turns or at low speeds,
which could result in an accident and possible
injury.
If the power-assist feature does not work due to hy-
draulic fluid loss, steering pump damage, or another
cause, bring the vehicle to a safe stop. Do not drive
the vehicle until the cause of the problem has been
corrected.
NOTICE
Never steam clean or high-pressure wash the
steering gear. Internal damage to gear seals, and
ultimately the steering gear, can result.
Drivers should carefully use the power available with
a power steering system. If the front tires become
lodged in a deep hole or rut, drive the vehicle out
instead of using the steering system to lift the tires
out of the hole.
NOTICE
Avoid turning the tires when they are against a
curb, as this places a heavy load on steering
components and could damage them.
