Tire Fill Alert (If Equipped)
This feature provides visual and

place.
2. Set the parking brake firmly.
3. Place the vehicle in P (Park).
4. Add air to the tire that is
underinflated. The turn signal lamp
will flash.
When the recommended pressure
is reached, the horn sounds once

Repeat these steps for all
underinflated tires that have
illuminated the low tire pressure
warning light.
