2010 CADILLAC ESCALADE check engine

If the word ON or the on symbol is lit on the passengerairbag status indicator, it means that the right frontpassenger frontal airbag is enabled (may inflate).
If the word OFF or the off symbol is lit on the airbagstatus indicator, it means that the passenger sensingsystem has turned off the right front passenger frontalairbag.
If, after several seconds, both status indicator lightsremain on, or if there are no lights at all, there may be aproblem with the lights or the passenger sensingsystem. See your dealer/retailer for service.
{WARNING:
If the airbag readiness light ever comes on and
stays on, it means that something may be wrong
with the airbag system. To help avoid injury to
yourself or others, have the vehicle serviced right
away. SeeAirbag Readiness Lighton page 4!30
for more information, including important safety
information.
Charging System Light
This light comes on brieflywhen the ignition key isturned to START, but theengine is not running, asa check to show it isworking.
If it does not, have the vehicle serviced by your dealer/retailer.
The light should go out once the engine starts. If it stayson, or comes on while driving, there could be a problemwith the charging system. A charging system messagein the Driver Information Center (DIC) can also appear.SeeDIC Warnings and Messageson page 4!48formore information. This light could indicate that there areproblems with a generator drive belt, or that there is anelectrical problem. Have it checked right away. If thevehicle must be driven a short distance with the light on,turn off accessories, such as the radio and airconditioner.

Engine Coolant Temperature Gage
This gage shows theengine coolanttemperature.
If the indicator on the gage moves towards the shadedarea on the thermostat, it means that the engine coolanthas overheated. If the vehicle has been operating undernormal driving conditions, pull off the road, stop thevehicle and turn off the engine as soon as possible.
SeeEngine Overheating on page 7!34.
Tire Pressure Light
For vehicles with a tirepressure monitoringsystem, this light comeson briefly when the engineis started. It providesinformation about tirepressures and the TirePressure MonitoringSystem.
When the Light is On Steady
This indicates that one or more of the tires issignificantly underinflated.
A tire pressure message in the Driver InformationCenter (DIC), can accompany the light. SeeDriverInformation Center (DIC)on page 4!41for moreinformation. Stop and check the tires as soon as it issafe to do so. If underinflated, inflate to the properpressure. SeeInflation - Tire Pressureon page 7!65for more information.

When the Light Flashes First and Then is
On Steady
This indicates that there may be a problem with the TirePressure Monitor System. The light flashes for about aminute and stays on steady for the remainder of theignition cycle. This sequence repeats with every ignitioncycle. SeeTire Pressure Monitor Operationonpage 7!68for more information.
Malfunction Indicator Lamp
Check Engine Light
A computer system called OBD II (On-BoardDiagnostics-Second Generation) monitors operationof the fuel, ignition, and emission control systems.It ensures that emissions are at acceptable levels forthe life of the vehicle, helping to produce a cleanerenvironment.
This light should come onwhen the ignition is on,but the engine is notrunning, as a check toshow it is working. If itdoes not, have the vehicleserviced by your dealer/retailer.
If the check engine light comes on and stays on, whilethe engine is running, this indicates that there is anOBD II problem and service is required.
Malfunctions often are indicated by the system beforeany problem is apparent. Being aware of the light canprevent more serious damage to the vehicle. Thissystem assists the service technician in correctlydiagnosing any malfunction.
Notice:If the vehicle is continually driven with thislight on, after a while, the emission controls mightnot work as well, the vehicle's fuel economy mightnot be as good, and the engine might not run assmoothly. This could lead to costly repairs thatmight not be covered by the vehicle warranty.
Notice:Modifications made to the engine,transmission, exhaust, intake, or fuel system of thevehicle or the replacement of the original tires withother than those of the same Tire PerformanceCriteria (TPC) can affect the vehicle's emissioncontrols and can cause this light to come on.Modifications to these systems could lead to costlyrepairs not covered by the vehicle warranty. Thiscould also result in a failure to pass a requiredEmission Inspection/Maintenance test. SeeAccessories and Modifications on page 7!4.

This light comes on during a malfunction in one oftwo ways:
Light Flashing :A misfire condition has been detected.A misfire increases vehicle emissions and coulddamage the emission control system on the vehicle.Diagnosis and service might be required.
To prevent more serious damage to the vehicle:
.Reduce vehicle speed.
.Avoid hard accelerations.
.Avoid steep uphill grades.
.If towing a trailer, reduce the amount of cargobeing hauled as soon as it is possible.
If the light continues to flash, when it is safe to do so,stop the vehicle. Find a safe place to park the vehicle.Turn the key off, wait at least 10 seconds, and restartthe engine. If the light is still flashing, follow theprevious steps and see your dealer/retailer for serviceas soon as possible.
Light On Steady :An emission control systemmalfunction has been detected on the vehicle.Diagnosis and service might be required.
An emission system malfunction might be corrected bydoing the following:
.Make sure the fuel cap is fully installed. SeeFillingthe Tankon page 7!11. The diagnostic systemcan determine if the fuel cap has been left off or
improperly installed. A loose or missing fuel capallows fuel to evaporate into the atmosphere. A fewdriving trips with the cap properly installed shouldturn the light off.
.If the vehicle has been driven through a deeppuddle of water, the vehicle's electrical systemmight be wet. The condition is usually correctedwhen the electrical system dries out. A few drivingtrips should turn the light off.
.Make sure to fuel the vehicle with quality fuel.Poor fuel quality causes the engine not to run asefficiently as designed and can cause: stalling afterstart-up, stalling when the vehicle is changed intogear, misfiring, hesitation on acceleration,or stumbling on acceleration. These conditionsmight go away once the engine is warmed up.
If one or more of these conditions occurs, changethe fuel brand used. It will require at least one fulltank of the proper fuel to turn the light off.
SeeGasoline Octane on page 7!8.
If none of the above have made the light turn off, yourdealer/retailer can check the vehicle. The dealer/retailerhas the proper test equipment and diagnostic tools to fixany mechanical or electrical problems that might havedeveloped.

Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have ormight begin programs to inspect the emission controlequipment on the vehicle. Failure to pass thisinspection could prevent getting a vehicle registration.
Here are some things to know to help the vehicle passan inspection:
.The vehicle will not pass this inspection if thecheck engine light is on with the engine running,or if the key is in ON/RUN and the light is not on.
.The vehicle will not pass this inspection if theOBD II (on-board diagnostic) system determinesthat critical emission control systems have notbeen completely diagnosed by the system.The vehicle would be considered not ready forinspection. This can happen if the battery hasrecently been replaced or if the battery has rundown. The diagnostic system is designed toevaluate critical emission control systems duringnormal driving. This can take several days ofroutine driving. If this has been done and thevehicle still does not pass the inspection for lack ofOBD II system readiness, your dealer/retailer canprepare the vehicle for inspection.
Oil Pressure Light
{WARNING:
Do not keep driving if the oil pressure is low.
The engine can become so hot that it catches fire.
Someone could be burned. Check the oil as soon
as possible and have the vehicle serviced.
Notice:Lack of proper engine oil maintenance candamage the engine. The repairs would not becovered by the vehicle warranty. Always follow themaintenance schedule in this manual for changingengine oil.
This light comes on briefly while starting the engine.If it does not, have the vehicle serviced by yourdealer/retailer. If the system is working normally theindicator light then goes off.
