2009 CADILLAC ESCALADE ESV Owners Manual

Engine Coolant Temperature Gage This gage shows
the engine coolant
temperature.
If the indicator on the gage moves towards the shaded
area on the thermostat, it means that the engine coolant
has overheated. If the vehicle has been operating under
normal driving conditions, pull off the road, stop the
vehicle and turn off the engine as soon as possible.
See Engine Overheating on page 6-30 .Tire Pressure Light For vehicles with a tire
pressure monitoring
system, this light comes
on briey when the engine
is started.
It provides information about tire pressures and the
Tire Pressure Monitoring System.
When the Light is On Steady This indicates that one or more of the tires is signicantly
underinated.
A tire pressure message in the Driver Information
Center (DIC), can accompany the light. See DIC
Warnings and Messages on page 3-56 for more
information. Stop and check the tires as soon as it is
safe to do so. If a tire is underinated, inate to the
proper pressure. See Tires on page 6-56 for more
information.
3-41

When the Light Flashes First and Then is
On Steady This indicates that there could be a problem with the
Tire Pressure Monitor System. The light ashes for about
a minute and stays on steady for the remainder of the
ignition cycle. This sequence repeats with every ignition
cycle. See Tire Pressure Monitor System on page 6-64
for more information.
Malfunction Indicator Lamp
Check Engine Light A computer system called OBD II (On-Board
Diagnostics-Second Generation) monitors operation
of the fuel, ignition, and emission control systems.
It ensures that emissions are at acceptable levels
for the life of the vehicle, helping to produce a cleaner
environment.
This light should come on
when the ignition is on, but
the engine is not running,
as a check to show it
is working. If it does not,
have the vehicle serviced
by your dealer/retailer. If the check engine light comes on and stays on, while
the engine is running, this indicates that there is an
OBD II problem and service is required.
Malfunctions often are indicated by the system before
any problem is apparent. Being aware of the light
can prevent more serious damage to the vehicle.
This system assists the service technician in correctly
diagnosing any malfunction.
Notice: If the vehicle is continually driven with
this light on, after a while, the emission controls
might not work as well, the vehicle’s fuel economy
might not be as good, and the engine might not
run as smoothly. This could lead to costly repairs
that might not be covered by the vehicle warranty.
Notice: Modications made to the engine,
transmission, exhaust, intake, or fuel system of
the vehicle or the replacement of the original tires
with other than those of the same Tire Performance
Criteria (TPC) can affect the vehicle’s emission
controls and can cause this light to come on.
Modications to these systems could lead to
costly repairs not covered by the vehicle warranty.
This could also result in a failure to pass a required
Emission Inspection/Maintenance test. See
Accessories and Modifications on page 6-3 .
3-42

This light comes on during a malfunction in one of
two ways:
Light Flashing: A misre condition has been detected.
A misre increases vehicle emissions and could
damage 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 cargo being
hauled as soon as it is possible.
If the light continues to ash, 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 restart
the engine. If the light is still ashing, follow the previous
steps and see your dealer/retailer for service as soon
as possible.
Light On Steady: An emission control system
malfunction has been detected on the vehicle.
Diagnosis and service might be required. An emission system malfunction might be corrected by
doing the following:
Make sure the fuel cap is fully installed. See Filling
the Tank on page 6-9 . The diagnostic system
can determine if the fuel cap has been left off or
improperly installed. A loose or missing fuel cap
allows fuel to evaporate into the atmosphere.
A few driving trips with the cap properly installed
should turn the light off.
If the vehicle has been driven through a deep puddle
of water, the vehicle’s electrical system might be wet.
The condition is usually corrected when the electrical
system dries out. A few driving trips should turn the
light off.
Make sure to fuel the vehicle with quality fuel. Poor
fuel quality causes the engine not to run as efficiently
as designed and can cause: stalling after start-up,
stalling when the vehicle is changed into gear,
misring, hesitation on acceleration, or stumbling
on acceleration. These conditions might go away
once the engine is warmed up.
If one or more of these conditions occurs, change the
fuel brand used. It will require at least one full tank of
the proper fuel to turn the light off.
See Gasoline Octane on page 6-5 .
If none of the above have made the light turn off, your
dealer/retailer can check the vehicle. The dealer/retailer
has the proper test equipment and diagnostic tools to
x any mechanical or electrical problems that might have
developed.

Emissions Inspection and Maintenance
Programs Some state/provincial and local governments have or
might begin programs to inspect the emission control
equipment on the vehicle. Failure to pass this inspection
could prevent getting a vehicle registration.
Here are some things to know to help the vehicle pass
an inspection:
The vehicle will not pass this inspection if the check
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 the
OBD II (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 the battery has recently
been replaced or if the battery has run down.
The diagnostic system is designed to evaluate
critical emission control systems during normal
driving. This can take several days of routine driving.
If this has been done and the vehicle still does
not pass the inspection for lack of OBD II system
readiness, your dealer/retailer can prepare the
vehicle for inspection. Oil Pressure Light
{ CAUTION: Do not keep driving if the oil pressure is low.
The engine can become so hot that it catches re.
Someone could be burned. Check the oil as soon
as possible and have the vehicle serviced.
Notice: Lack of proper engine oil maintenance
can damage the engine. The repairs would not be
covered by the vehicle warranty. Always follow
the maintenance schedule in this manual for
changing engine oil.
3-44

This light comes on briey while starting the engine.
If it does not, have the vehicle serviced by your
dealer/retailer. If the system is working normally
the indicator light then goes off.
If the light comes on and stays on, it means that oil is
not owing through the engine properly. The vehicle
could be low on oil and it might have some other system
problem.
Security Light For information regarding
this light and the vehicle’s
security system, see
Content Theft-Deterrent
on page 2-21 .Fog Lamp Light The fog lamp light comes
on when the fog lamps are
in use.
The light goes out when the fog lamps are turned off.
See Fog Lamps on page 3-22 for more information.
Lights On Reminder This light comes on
whenever the parking
lamps are on.
See Exterior Lamps on page 3-16 for more information.
3-45

Cruise Control Light The cruise control light
comes on whenever the
cruise control is set.
The light goes out when the cruise control is turned off.
See Cruise Control on page 3-13 for more information.
Highbeam On Light This light comes on when
the high-beam headlamps
are in use.
See Headlamp High/Low-Beam Changer on page 3-8
for more information. Tow/Haul Mode Light This light comes on when
the Tow/Haul mode has
been activated.
For more information, see Tow/Haul Mode on page 2-33 .
Fuel Gage When the ignition is on, the
fuel gage shows about how
much fuel the vehicle has
left in the tank.
An arrow on the fuel gage indicates the side of the
vehicle the fuel door is on.
3-46

The gage will rst indicate empty before the vehicle
is out of fuel, but the vehicle’s fuel tank should be
lled soon.
Here are some situations owners may experience
with the fuel gage. None of these indicate a problem
with the fuel gage.
At the gas station, the fuel pump shuts off before
the gage reads full.
It takes a little more or less fuel to ll up than the
fuel gage indicated. For example, the gage may
have indicated the tank was half full, but it actually
took a little more or less than half the tank’s
capacity to ll the tank.
The gage goes back to empty when the ignition is
turned off. Driver Information Center (DIC) Your vehicle has a Driver Information Center (DIC).
The DIC displays information about your vehicle.
It also displays warning messages if a system problem
is detected. The DIC also allows some features to be
customized. See DIC Vehicle Customization on
page 3-65 for more information.
All messages will appear in the DIC display located in
the center of the instrument panel cluster.
The DIC comes on when the ignition is on. After a short
delay, the DIC will display the information that was last
displayed before the engine was turned off.
