Tires should be inflated to the recommended pressures (as given in the owners handbook) only when the tires are cold (ambient temperature). If the tires have been subjected to use or exposed to direct sunlight, move the vehicle into a shaded position and allow the tires to cool before checking and/or adjusting the pressures. |

If tires and wheels of a non-standard size are fitted to the vehicle, the car configuration file must be updated using T4. |

During a ‘blow out’ a very rapid reduction in pressure is experienced. The system is not intended to warn the driver of a ‘blow out’, since it is not possible to give the driver sufficient warning that such an event is occurring, due to its short duration. The design of the TPMS is to assist the driver in keeping the tires at the correct pressure, which will tend to reduce the likelihood of a tire ‘blow out’ occurring. |
The TPMS switch is not fitted to NAS market vehicles. NAS vehicles do not have the option to select target pressure modes. |
