7. Train the TPMS sensors in the tires using the following TPMS reset
sequence starting with the left front tire in the following clockwise
order:
1. Left front tire (Front driver’s side)
2. Right front tire (Front passenger’s side)
3. Right rear tire (Rear passenger’s side)
4. Left rear tire (Rear driver’s side)
8. Left front tire: Place the TPMS reset tool against the left front tire
where the tire meets the rim, right near the valve stem (1) as shown.
This is where the sensor is located inside the rim.
The tool needs to be held against the tire sidewall right near the
valve stem as illustrated with the arrow on the tool pointing
towards the rim; do not use the tool with the arrow pointing away
from the rim as it may not activate the sensor.
9. Press and release the green button and hold the tool to the tire
sidewall until the horn sounds. The red light on the TPMS reset tool will
illuminate while the tool is active. The horn will sound once within
10 seconds to indicate the process was successful.
