2008 CADILLAC ESCALADE ESV service reset

Always reset the engine oil life to 100% after every oil
change. It will not reset itself. To reset the Engine
Oil Life System:
1. Display the OIL LIFE REMAINING on the DIC.
2. Press and hold the SET/RESET button on the DIC
for more than ve seconds. The oil life will change
to 100%.
If the CHANGE ENGINE OIL SOON message comes
back on when you start your vehicle, the Engine Oil
Life System has not reset. Repeat the procedure.
What to Do with Used Oil Used engine oil contains certain elements that can be
unhealthy for your skin and could even cause cancer.
Do not let used oil stay on your skin for very long. Clean
your skin and nails with soap and water, or a good
hand cleaner. Wash or properly dispose of clothing or
rags containing used engine oil. See the manufacturer’s
warnings about the use and disposal of oil products.
Used oil can be a threat to the environment. If you
change your own oil, be sure to drain all the oil from the
lter before disposal. Never dispose of oil by putting it
in the trash, pouring it on the ground, into sewers, or into
streams or bodies of water. Instead, recycle it by
taking it to a place that collects used oil. If you have a
problem properly disposing of used oil, ask your
dealer/retailer, a service station, or a local recycling
center for help. Engine Air Cleaner/Filter See Engine Compartment
Overview on page 5-12 for
the location of the engine
air cleaner/lter and
the air lter restriction
indicator, if the vehicle
has one.
When to Inspect the Engine Air
Cleaner/Filter If your vehicle has an air lter restriction indicator, it lets
you know when the engine air cleaner/lter needs to
be replaced. On vehicles with a restriction indicator,
you should inspect the air lter restriction indicator
at every oil change and replace the engine air
cleaner/lter when the indicator tells you to.
On vehicles without an air lter restriction indicator,
inspect the air cleaner/lter at the Maintenance II
intervals and replace it at the rst oil change after
each 50,000 mile (80 000 km) interval. See Scheduled
Maintenance on page 6-4 for more information.
If you are driving in dusty/dirty conditions, inspect the
lter at each engine oil change.

If you no longer have the overheat warning, you can
drive. Just to be safe, drive slower for about 10 minutes.
If the warning does not come back on, you can drive
normally.
If the warning continues, pull over, stop, and park your
vehicle right away.
If there is still no sign of steam and your vehicle has an
engine-driven cooling fan, push down the accelerator
until the engine speed is about twice as fast as
normal idle speed for at least ve minutes while you
are parked.
If there is still no sign of steam and your vehicle has
an electric cooling fan, idle the engine for at least
ve minutes while you are parked.
If you still have the warning, turn off the engine and get
everyone out of the vehicle until it cools down. Also,
see “Overheated Engine Protection Operating Mode”
later in this section.
You may decide not to lift the hood but to get service
help right away. Overheated Engine Protection
Operating Mode If an overheated engine condition exists and the
ENGINE POWER IS REDUCED message is displayed,
an overheat protection mode which alternates ring
groups of cylinders helps prevent engine damage.
In this mode, you will notice a loss in power and engine
performance. This operating mode allows your vehicle
to be driven to a safe place in an emergency. Driving
extended miles (km) and/or towing a trailer in the
overheat protection mode should be avoided.
Notice: After driving in the overheated engine
protection operating mode, to avoid engine damage,
allow the engine to cool before attempting any
repair. The engine oil will be severely degraded.
Repair the cause of coolant loss, change the oil
and reset the oil life system. See Engine Oil
on page 5-14 .

Headlamp Aiming The vehicle has a visual optical headlamp aiming
system. The aim of the headlamps have been preset at
the factory and should need no further adjustment.
However, if the vehicle is damaged in a crash, the aim
of the headlamps may be affected and adjustment
may be necessary.
If oncoming vehicles ash their high beams at you,
this may mean the vertical aim of your headlamps
needs to be adjusted.
It is recommended that the vehicle is taken to your
dealer/retailer for service if the headlamps need
to be adjusted. It is possible however, to re-aim the
headlamps as described. The vehicle should:
Be placed so the headlamps are 25 ft. (7.6 m) from
a light colored wall or other at surface.
Have all four tires on a level surface which is level
all the way to the wall or other at surface.
Be placed so it is perpendicular to the wall or other
at surface.
Not have any snow, ice, or mud on it.
Be fully assembled and all other work stopped while
headlamp aiming is being performed.
Be normally loaded with a full tank of fuel and one
person or 160 lbs (75 kg) sitting on the driver seat.
Have the tires properly inated.
Have the spare tire is in its proper location in the
vehicle.

The proper replacement parts, uids, and lubricants to
use are listed in Recommended Fluids and Lubricants
on page 6-13 and Maintenance Replacement Parts
on page 6-15 . When your vehicle is serviced, make sure
these are used. All parts should be replaced and all
necessary repairs done before you or anyone else
drives the vehicle. We recommend the use of genuine
parts from your dealer/retailer.
Scheduled Maintenance To maintain the ride, handling, and performance of your
vehicle, it is important that the rst tire rotation service
be performed when the vehicle has 5,000 to 8,000 miles
(8 000 to 13 000 km). Check tires for ination pressures
and wear. See Tires on page 5-56 . Rotate tires. See
Tire Inspection and Rotation on page 5-69 and
“Tire Wear Inspection” in At Least Once a Month on
page 6-10 . When the CHANGE ENGINE OIL SOON message
comes on, it means that service is required for your
vehicle. Have your vehicle serviced as soon as possible
within the next 600 miles (1 000 km). It is possible
that, if you are driving under the best conditions, the
engine oil life system may not indicate that vehicle
service is necessary for over a year. However,
the engine oil and lter must be changed at least once
a year and at this time the system must be reset.
Your dealer/retailer has trained service technicians who
will perform this work using genuine parts and reset
the system.
If the engine oil life system is ever reset accidentally,
you must service your vehicle within 3,000 miles
(5 000 km) since your last service. Remember to reset
the oil life system whenever the oil is changed. See
Engine Oil Life System on page 5-16 for information on
the Engine Oil Life System and resetting the system.
