How to adjust seating to the proper position while driving
Slide your seat until your knees are slightly bent when you're pressing the gas.
Move your seat forward if your legs are completely extended when you press the gas pedal. Move your seat back if your legs are bent too much.

Choices:
- Move your seat in the opposite direction the airbags are intended to go. Do this in the direction that the airbags are intended to go before the stop signs have been passed.
- Tighten your seat before pressing the gas pedal. To press the gas pedal, tighten your seat only as close to the floor as is appropriate.
- Wait until you are fully seated before pressing the gas pedal. To start the vehicle, shift forward slowly into starting position with the handbrake a few inches from the floor and the engine on.
- Keeping your knees slightly bent while you drive will prevent knee pain. Sit so there's a gap 2 fingers wide between the back of your knee and the seat.
