STEERING CHECK Turn the steering wheel     while   traveling   slowly   to   see that the steering forces are equal in right and left or that any abnormality does not exist. CAUTION The    steering    system    employs    the power  steering.    While  the  engine  is shut down, the power steering becomes          ineffective,     causing     a heavy steering operation.
