    Tilt Steering / Telescope Steering

    Adjust the steering wheel so 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.


    NEVER adjust the steering wheel while driving. This may cause loss of vehicle control resulting in an accident.
