I have the paper printed version.
My page 486 is about tire pressure monitoring.
Because there is a discrepancy, between our owner's manuals, here is what have in my book:
The "P" button needs to be green. It's to the left of the steering wheel. If it is not "green", the following step 5 will be grayed out and unavailable.
My page 545 shows to turn on/off all rear sensors.
My page 547 tells how the Cross Traffic Sys works.
My page 549 shows how to use the "audio/information screen to turn Cross Traffic System On/Off:
1. On the radio display screen press "Home" icon.
2. Settings
3. Camera
4. Rear Camera
5. Cross Traffic Monitor
6. On or Off
There is a note on page 549...The system can also be turned on and off, on the audio/information screen, by pressing the "CTM" icon.
