ÿ Operating sound of EPS motor
When you operate the steering wheel, you may hear the sound of the motor ("whining" sound), but it is
not a malfunction.
ÿ Automatic recovery of TRC and VSC
Even if the TRC and VSC are disabled, they will automatically return to the operable state when the hybrid
system is restarted after being stopped. ÿ TRC OFF operation restrictions
If only the TRC is deactivated, the TRC will resume operation when the vehicle speed increases. However,
if
the TRC and VSC are deactivated, they will not restart depending on vehicle speed.
ÿ When the effect of EPS decreases
If you turn the steering wheel for a long time while stationary or driving at very low speeds, the EPS will
become less effective and the steering will feel heavier in order to avoid overheating the EPS system. In
that case,
refrain from steering or stop the vehicle to stop the hybrid system. It will return to its original state in about
10 minutes.
