• 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.
