3-38 Seats and Restraints Satisfaction Procedure (U.S. and Canada) on page 13‑3 or Customer Satisfaction Procedure (Mexico) on page 13‑3. In addition, your dealer and the service manual have information about the location of the airbag sensors, sensing and diagnostic module and airbag wiring. Where Are the Airbags? on page 3‑23. See your dealer for service. Q: What if I added a snow plow? Will it keep the airbags from working properly? A: We have designed our airbag systems to work properly under a wide range of conditions, including snow plowing with vehicles that have the optional Snow Plow Prep Package (RPO VYU). But do not change or defeat the snow plow's "tripping mechanism." If you do, it can damage your snow plow and your vehicle, and it may cause an airbag inflation. Q: Because I have a disability, I have to get my vehicle modified. How can I find out whether this will affect my airbag system? A: If you have questions, call Customer Assistance. The phone numbers and addresses for Customer Assistance are in Step Two of the Customer Satisfaction Procedure in this manual. See Customer Replacing Airbag System Parts after a Crash { WARNING A crash can damage the airbag systems in the vehicle. A damaged airbag system may not work properly and may not protect you and your passenger(s) in a crash, resulting in serious injury or even death. To help make sure the airbag systems are working properly after a crash, have them inspected and any necessary replacements made as soon as possible. Airbag System Check The airbag system does not need regularly scheduled maintenance or replacement. Make sure the airbag readiness light is working. See Airbag Readiness Light on page 5‑18. Notice: If an airbag covering is damaged, opened, or broken, the airbag may not work properly. Do not open or break the airbag coverings. If there are any opened or broken airbag covers, have the airbag covering and/or airbag module replaced. For the location of the airbags, see
