2010 CADILLAC ESCALADE check engine light

For example, if the lock button and then the remote startbuttons are pressed again after the vehicle has beenrunning for five minutes, 10 minutes are added, allowingthe engine to run for 15 minutes.
The additional ten minutes are considered a secondremote vehicle start.
After your vehicles engine has been started two timesusing the remote vehicle start button, or a single remotestart with one time extension, the vehicle must bestarted with the key.
After the key is removed from the ignition, the vehiclecan be remote started again.
The vehicle cannot be remote started if the key is inthe ignition, the hood is not closed, or if there is anemission control system malfunction and the checkengine light comes on.
Also, the engine will turn off during a remote vehiclestart if the coolant temperature gets too high or if the oilpressure gets low.
Vehicles that have the remote vehicle start feature areshipped from the factory with the remote vehicle startsystem enabled. The system may be enabled ordisabled through the DIC. See“REMOTE START”underDIC Vehicle Customizationon page 4!57foradditional information.

PASS-Key®III+ Electronic
Immobilizer
SeeRadio Frequency Statementon page 9!20forinformation regarding Part 15 of the FederalCommunications Commission (FCC) Rules andRSS-210/211 of Industry and Science Canada.
PASS-Key®III+ Electronic
Immobilizer Operation
Your vehicle has PASS-Key®III+ (PersonalizedAutomotive Security System) theft-deterrent system.PASS-Key®III+ is a passive theft-deterrent system.
The system is automatically armed when the key isremoved from the ignition.
The system is automatically disarmed when the key isturned to ON/RUN, ACC/ACCESSORY or START fromthe LOCK/OFF position.
You do not have to manually arm or disarm the system.
The security light will come on if there is a problem witharming or disarming the theft-deterrent system.
When the PASS-Key®III+ system senses that someoneis using the wrong key, it prevents the vehicle fromstarting. Anyone using a trial-and-error method to startthe vehicle will be discouraged because of the highnumber of electrical key codes.
If the engine does not start and the security light onthe instrument panel cluster comes on when trying tostart the vehicle, there may be a problem with yourtheft-deterrent system. Turn the ignition off andtry again.
If the engine still does not start, and the key appears tobe undamaged, try another ignition key. At this time,you may also want to check the fuse, seeFuses andCircuit Breakerson page 7!108. If the engine still doesnot start with the other key, your vehicle needs service.

Warning Lights, Gages, and
Indicators
Warning lights and gages can signal that something iswrong before it becomes serious enough to cause anexpensive repair or replacement. Paying attention to thewarning lights and gages could prevent injury.
Warning lights come on when there might be or there isa problem with one of the vehicle's functions. Somewarning lights come on briefly when the engine isstarted to indicate they are working.
Gages can indicate when there might be or there is aproblem with one of the vehicle's functions. Often gagesand warning lights work together to indicate a problemwith the vehicle.
When one of the warning lights comes on and stays onwhile driving, or when one of the gages shows therecould be a problem, check the section that explainswhat to do. Follow this manual's advice. Waiting to dorepairs can be costly and even dangerous.

Speedometer and Odometer
The speedometer shows the vehicle's speed in bothkilometers per hour (km/h) and miles per hour (mph).
The vehicle's odometer works together with the DriverInformation Center (DIC). The Trip odometer can be set.See“Trip Odometer”underDIC Operation and Displayson page 4!41for more information.
To check the odometer mileage while the vehicle is notrunning, press the trip stem on the instrument panelcluster.
If the vehicle ever needs a new odometer installed, thenew one will be set to the correct mileage total of theold odometer.
Trip Odometer
The trip odometer can show how far the vehicle hasbeen driven since the trip odometer was last set to zero.
For more information see“Trip Odometer”underDICOperation and Displays on page 4!41.
Tachometer
The tachometer displays the engine speed inrevolutions per minute (rpm).
Safety Belt Reminders

Airbag Readiness Light
The system checks the airbag's electrical system forpossible malfunctions. If the light stays on it indicatesthere is an electrical problem. The system checkincludes the airbag sensor, the pretensioners, theairbag modules, the wiring and the crash sensing anddiagnostic module. For more information on the airbagsystem, seeAirbag System on page 2!74.
The airbag readiness lightcomes on solid for a fewseconds when the engineis started. If the light doesnot come on then, have itfixed immediately.

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

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.
