A tilt steering wheel allows you to adjust the steering wheel before you drive. You can raise it to the highest level to give your legs more room when you exit and enter the vehicle, or you can lower it so that you're more comfortable while driving.
The lever to adjust it is located on the left side of the steering column, below the turn signal/multifunction lever.
To tilt the wheel, hold the steering wheel and pull the lever. Move the steering wheel to a comfortable level, then release the lever to lock the wheel in place.
