Horn

To sound the horn, press the center pad on the
steering wheel.

Tilt Wheel

Your vehicle has a tilt wheel, that lets you adjust
the steering wheel before driving. Raising it to
the highest level gives more room to exit and enter
your vehicle.
The tilt steering wheel lever is located on the
lower left side of the column.
To tilt the wheel, hold the steering wheel and pull
the lever. Then move the steering wheel to a
comfortable position and release the lever to lock
the wheel in place.
