Hyundai Elantra HD: Electronic power steering
Power steering uses the motor to assist you in steering the vehicle. If the engine is off or if the power steering system becomes inoperative, the vehicle may still be steered, but it will require increased steering effort.
The motor driven power steering is controlled by power steering control unit which sense the steering wheel torque, steering wheel position and vehicle speed to command the motor.
The steering wheel becomes heavier as the vehicle’s speed increases and becomes lighter as the vehicle’s speed decreases for the better control of the steering wheel.
Should you notice any change in the effort required to steer during normal vehicle operation, have the power steering checked by an authorized Hyundai dealer.
✽ NOTICE
The following symptoms may occur during normal vehicle operation:
- The EPS warning light does not illuminate.
- The steering wheel becomes heavier after turning the ignition switch on. This happens as the system performs the EPS system diagnostics. When the diagnostics is completed, the steering wheel will return to its normal condition.
- Click noise may be heard from the EPS relay after the ignition switch is turned to the ON or LOCK position.
- Motor noise may be heard when the vehicle is at a stop or at a low driving speed.
- The steering effort can suddenly increase, if the operation of EPS system is stopped to prevent serious accidents when the malfunction of EPS system is detected by self-diagnosis.
