Electric Power Steering
If the engine stalls while you are driving, the
power steering assist system will continue
to operate until you are able to stop your vehicle.
If you lose power steering assist because the
electric power steering system is not functioning,
you can steer, but it will take more effort.
If you turn the steering wheel in either direction
several times until it stops, or hold the steering
wheel in the stopped position for an extended
amount of time, you may notice a reduced amount
of power steering assist. The normal amount of
power steering assist should return shortly after
a few normal steering movements.
The electric power steering system does not
require regular maintenance. If you suspect
steering system problems, such as abnormally
high steering effort for a prolonged period of time,
contact your dealer for service repairs.
