UK_AURIS/AURIS_HV_EE (OM12E33E)Reduced effectiveness of the EPS system
Except hybrid model: The effectiveness of the EPS system is reduced to pre-
vent the system from overheating when there is frequent steering input over
an extended period of time. The steering wheel may feel heavy as a result.
Should this occur, refrain from excessive steering input or stop the vehicle
and turn the engine off. The EPS system should return to normal within 10
minutes.
Hybrid model: The effectiveness of the EPS system is reduced to prevent the
system from overheating when there is frequent steering input over an
extended period of time. The steering wheel may feel heavy as a result.
