- Make sure nothing is on the front passenger's seat, including after market seat covers or mats.
- Make sure there is nothing in the front passenger's seat-back pocket.
- Keep the windows and the moonroof closed.
- Do all initialization procedures, except test-driving, in the service bay.
- Make sure the vehicle is on level ground.

- Do not touch the passenger's seat during the operation check.
- Do not expose the front passenger's seat to sudden temperature changes.
- Make sure all after market devices such as amplifiers, fluorescent light, air purifiers, CB or HAM radios, etc. are turned off.
