CAUTION

• Ensure valve cap is always in place except when adjusting tire pressure.
• If the valve core and valve cap are replaced, use a genuine replacement part. The valve core is 

similar to a conventional one, but uses nickel plating to avoid corrosion.

• Do not drop the TPMS transmitter from height greater than 1 meter (3.3 feet).
• Do not expose the TPMS transmitter to extraneous magnetic fields.
• TPMS transmitter should not be stored at temperatures above 80°C (176°F).
• TPMS transmitter should not be exposed to temperatures above 100°C (212°F).
• If the TPMS transmitter is replaced, execute "Tire Pressure Sensor ID Registration" on scan tool 

MB991958 "Special Function." 

• Be careful not to damage the TPMS transmitter.

Pre-removal Operation
