Hyundai Equus: Electronic Hydraulic Power Steering (EHPS)

This system uses an electromotor to assist you with steering the vehicle.

If the engine is turned off or if the EHPS becomes inoperative, you may still steer the vehicle, but it will require increased steering effort.

Should you notice any change in the effort required to steer during normal vehicle operation, have the EHPS checked by an authorized EQUUS dealer.

CAUTION

Do not hold the steering wheel to the extreme right or left for more than five (5) seconds with the engine running. This may cause damage to the EHPS motor pump.

✽ NOTICE

If the EHPS motor pump malfunctions, the steering effort will greatly increase.

✽ NOTICE

If the vehicle is parked for extended periods outside in cold weather (below 14°F/-10°C), the power steering may require increased effort when the engine is first started. This is caused by increased fluid viscosity due to the cold weather and does not indicate a malfunction. When this happens, increase the engine RPM by depressing accelerator until the RPM reaches 1,500 rpm then release or let the engine idle for two or three minutes to warm up the fluid.
