2007 CADILLAC ESCALADE EXT check engine

Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel.
SeeGasoline Octane on page 399. Poor fuel
quality will cause your engine not to run as
efficiently as designed. You may notice this as
stalling after start-up, stalling when you put
the vehicle into gear, misring, hesitation on
acceleration, or stumbling on acceleration.
(These conditions may go away once the engine
is warmed up.) This will be detected by the
system and cause the light to turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at
least one full tank of the proper fuel to turn the
light off.
If none of the above steps have made the light
turn off, your dealer can check the vehicle.
Your dealer has the proper test equipment and
diagnostic tools to x any mechanical or electrical
problems that may have developed.Emissions Inspection and
Maintenance Programs
Some state/provincial and local governments have
or may begin programs to inspect the emission
control equipment on your vehicle. Failure to pass
this inspection could prevent you from getting a
vehicle registration.
Here are some things you need to know to help
your vehicle pass an inspection:
Your vehicle will not pass this inspection if the
check engine light is on or not working properly.
Your vehicle will not pass this inspection if
the OBD (on-board diagnostic) system determines
that critical emission control systems have not
been completely diagnosed by the system.
The vehicle would be considered not ready for
inspection. This can happen if you have recently
replaced your battery or if your battery has
run down. The diagnostic system is designed
to evaluate critical emission control systems during
normal driving. This may take several days of
routine driving. If you have done this and
your vehicle still does not pass the inspection for
lack of OBD system readiness, your GM dealer
can prepare the vehicle for inspection.

Oil Pressure Light
This light will come on
briey when you start
your engine.
{CAUTION:
Do not keep driving if the oil pressure is

could be burned. Check your oil as soon
as possible and have your vehicle
serviced.
Notice:Lack of proper engine oil maintenance
may damage the engine. The repairs would
not be covered by your warranty. Always follow
the maintenance schedule in this manual for
changing engine oil.That is a check to be sure the light works. If it
does not come on, be sure to have it xed so it will
be there to warn you if something goes wrong.
When the light comes on and stays on, it means
that oil is not owing through your engine

Tire Pressure
If your vehicle has a Tire Pressure Monitor (TPM)
system, the pressure for each tire can be viewed in
the DIC. The tire pressure will be shown in either
pounds per square inch (psi) or kilopascals (kPa).
Press the vehicle information button until the DIC
displays FRONT TIRES PSI (kPa) LEFT ##
RIGHT ##. Press the vehicle information button
again until the DIC displays REAR TIRES PSI (kPa)
LEFT ## RIGHT ##.If a low or high tire pressure condition is detected
by the system while driving, a message advising
you to check the pressure in a specic tire
will appear in the display. SeeInation - Tire
Pressure on page 460andDIC Warnings
and Messages on page 248for more information.
If the tire pressure display shows dashes
instead of a value, there may be a problem with
your vehicle. If this consistently occurs, see
your dealer for service.
Relearn Tire Positions
If your vehicle has a Tire Pressure Monitor (TPM)
system, after rotating the tires or after replacing
a tire or sensor, the system must re-learn the tire
positions. To re-learn the tire positions, see
Tire Pressure Monitor System on page 462. See
Tire Inspection and Rotation on page 467andDIC
