*1 If tires and/or rims are wider, the load to power steering system is the more. Accordingly, in a
condition, for example before fluid warms-up, relief valve may work before maximum turning angle.
In this case, steering effort may be heavy. When measured hydraulic pressure is normal, there is
no abnormal thing.
*2 In cold weather, steering effort may be heavy due to increased flow resistance of cold fluid. After
warming up engine, turn steering wheel from stop to stop several times to warm up fluid. Then if
steering effort reduces normally, there is no abnormal thing.
*3 In cold weather or with insufficient warm-up of engine, steering effort may be heavy due to exces-
sive drop of idling when turning steering wheel. In this case, it is recommended to start the vehicle
with increasing engine speed than usual. Then if steering effort reduces normally, there is no
abnormal thing. Measure hydraulic pressure.
