GMC Terrain: Warning Lights, Gauges, and Indicators / Tire Pressure Light
For vehicles with the Tire Pressure Monitor System (TPMS), this light comes on briefly when the engine is started. It provides information about tire pressures and the TPMS.
When the Light Is On Steady
This indicates that one or more of the tires are significantly underinflated.
A Driver Information Center (DIC) tire pressure message may also display. Stop as soon as possible, and inflate the tires to the pressure value shown on the Tire and Loading Information label. See Tire Pressure.
When the Light Flashes First and Then Is On Steady
If the light flashes for about a minute and then stays on, there may be a problem with the TPMS. If the problem is not corrected, the light will come on at every ignition cycle. See Tire Pressure Monitor Operation.
Wait-to-Start Light
For diesel engines, the wait-to-start
light shows that the engine is
functioning properly and indicates
when the engine can be started.
The fast warm-up glow plug system
makes the wait-to-start light stay on
for a shorter amount of time than
most diesel engines...
Engine Oil Pressure Light
Caution
Lack of proper engine oil
maintenance can damage the
engine. Driving with the engine oil
low can also damage the engine.
The repairs would not be covered
by the vehicle warranty...
