Pontiac 2006 manual Tire Pressure Monitor System

Tire Pressure Monitor System

If your vehicle has this feature, it is designed to alert you when the system detects a large change in

the pressure of one tire. The system cannot alert you before you drive that a tire is low or flat. You must begin driving before the system will work properly. The system works with the brake control system and is designed to detect differences in the tire rotation speeds that are caused by changes in tire pressure. The tire pressure monitoring system does not replace normal tire maintenance, see Tires on page 5-52, Tire Inspection and Rotation on page 5-62and When It Is Time for New Tires on page 5-64.

This light, on the instrument panel cluster, comes on when the tire pressure monitoring system detects a low-tire condition.

This light will also come on for a few seconds and then go off when you turn the ignition to ON. This indicates that the tire pressure monitoring system is functioning properly. If the low-tire pressure warning light comes on while driving your vehicle, the system may have

5-60

detected a low-tire condition. You need to stop as soon as possible and check your tires for damage. If a tire is flat, see If a Tire Goes Flat on page 5-69and Changing a Flat Tire on page 5-70. Also check the tire pressure in all four tires, and set them to the specified level shown on the tire and loading label.

See Inflation - Tire Pressure on page 5-58 for additional information.

Note: The tire pressure monitoring system on your vehicle will warn you when one of your tires is significantly under-inflated and when some combinations of your tires are significantly under-inflated. However, there are other combinations of significantly under-inflated tires for which your tire pressure monitoring system may not warn you. These other combinations are relatively common, accounting

for approximately half the instances in which vehicles have significantly under-inflated tires. For example, your system may not warn you when both tires on the same side or on the same axle of your vehicle are significantly under-inflated. It is particularly important, therefore, for you to check the tire pressure in all of your tires regularly and maintain proper pressure.

In order for the tire pressure monitoring system to work properly you will need to reset (initialize) the tire pressure monitoring system. Any time you check and/or adjust a tire’s pressure, repair or replace a tire or wheel or rotate the tires the tire pressure monitor system needs to be reset.
