• A click noise may be heard from the MDPS relay after the Start/Stop button is in the ON 
or OFF position.
• Motor noise may be heard when the vehicle  is at a stop or at a low driving speed.
• When you operate the steering wheel in low  temperatures, abnormal noise may occur. If 
the temperature rises, the noise will 
disappear. This is a normal condition.
• When an error is detected from MDPS, the  steering effort assist function will not be 
activated in order to prevent fatal accidents. 
Instrument cluster warning lights may be on 
or the steering effort may be high. If these 
symptoms occur, drive the vehicle to a safe 
area as soon as it is safe to do so. Have the 
system inspected by an authorized 
HYUNDAI dealer as soon as possible.
 
Tilt/Telescopic Steering
When adjusting the steering wheel to a 
comfortable position, adjust the steering 
wheel so that it points toward your chest, 
not toward your face. Make sure you can 
see the instrument cluster warning lights 
and gauges. After adjusting, push the 
steering wheel both up and down to be 
certain it is locked in position.
Always adjust the position of the steering 
wheel before driving.
WARNING NEVER adjust the steering wheel while 
driving. This may cause loss of vehicle 
control resulting in an accident.
