2010 CADILLAC DTS instrument cluster

4. With the coolant surge tank cap off, start the engineand let it run until you can feel the upper radiatorhose getting hot. Watch out for the enginecooling fans.
By this time, the coolant level inside the coolantsurge tank may be lower. If the level is lower, addmore of the proper mixture to the coolant surge tankuntil the level reaches the FULL COLD mark onthe side of the coolant surge tank.
5. Replace the cap. Be sure the cap is hand-tight andfully seated.
Notice:If the pressure cap is not tightly installed,coolant loss and possible engine damage mayoccur. Be sure the cap is properly and tightlysecured.
If coolant is needed, add the proper DEX-COOL®
coolant mixture at the coolant recovery tank.
Engine Overheating
The vehicle has several indicators to warn of engineoverheating.
There is an engine temperature warning light and/orgage on the instrument panel cluster. SeeEngineCoolant Temperature Warning Light on page 4-55andEngine Coolant Temperature Gage on page 4-56.
The vehicle may also display a ENGINE OVERHEATEDIDLE ENGINE message or an ENGINE OVERHEATEDSTOP ENGINE message displayed in the DriverInformation Center (DIC). SeeDIC Warnings andMessages on page 4-67for more information. You willalso hear a chime.

Your vehicle has also been equipped with a TPMSmalfunction indicator to indicate when the system is notoperating properly. The TPMS malfunction indicatoris combined with the low tire pressure telltale. When thesystem detects a malfunction, the telltale will flash forapproximately one minute and then remain continuouslyilluminated. This sequence will continue uponsubsequent vehicle start-ups as long as themalfunction exists.
When the malfunction indicator is illuminated, thesystem may not be able to detect or signal low tirepressure as intended. TPMS malfunctions may occur fora variety of reasons, including the installation ofreplacement or alternate tires or wheels on the vehiclethat prevent the TPMS from functioning properly.Always check the TPMS malfunction telltale afterreplacing one or more tires or wheels on your vehicle toensure that the replacement or alternate tires andwheels allow the TPMS to continue to function properly.

Tire Pressure Monitor Operation
This vehicle may have a Tire Pressure Monitor System(TPMS). The TPMS is designed to warn the driverwhen a low tire pressure condition exists. TPMS sensorsare mounted onto each tire and wheel assembly,excluding the spare tire and wheel assembly. The TPMSsensors monitor the air pressure in the vehicle’s tiresand transmits the tire pressure readings to a receiverlocated in the vehicle.
When a low tire pressurecondition is detected, theTPMS illuminates thelow tire pressure warninglight located on theinstrument panel cluster.
