GB SET WARNING LEVELS
Your TPM system is equipped with a 2-stage warning system:
1. First warning is given for pressure loss situations of 25% or more.
2. Second - more firm - alarm is given for pressure loss of 50% or more.
Note: the manufacturer strongly recommends maintaining default system settings to
avoid false alarms triggered by temperature/pressure variations.
Note: using lower minimum level settings may result in dangerous driving situations.
Note: the high pressure alert is deleted if the set pressure level is above 52 PSI
Default system settings are 25% for the first stage warning and 50% for the second
stage alert. Pressure levels can be adjusted upon personal preference using following
