Other Warning Devices
If you carry reflective triangles, you can set one up at
the side of the road about 300 feet (100 m) behind your
vehicle.
Horn
Press the horn symbols on your steering wheel pad to
sound the horn.
Tilt Wheel
Your vehicle has a tilt wheel which 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.
The lever that allows you to tilt the steering wheel is
located under the steering column.
To tilt the steering wheel, hold the wheel and push the
lever away from you. Then, move the wheel to a
comfortable position and pull the lever toward you to
lock the wheel in place.
