How to Reset the Engine Oil Life
System
Reset the system whenever the engine
oil is changed so that the system can
calculate the next engine oil change.
To reset the system:1. Using the vehicle information screen controls on the right side of
the instrument cluster, display OIL
LIFE on the screen. See Vehicle
Information 0136. When remaining
oil life is low, the CHANGE
ENGINE OIL SOON message will
appear on the display.
2. Touch RESET on the screen to clear the CHANGE ENGINE OIL
SOON message and reset the oil life
at 100%.
Be careful not to reset the oil life
display accidentally at any time
other than after the oil is changed.
It cannot be reset accurately until
the next oil change.
The oil life system can also be reset as
follows: 1. Display OIL LIFE on the vehicle information screen. See Vehicle
Information 0136. 2. Fully press and release the
accelerator pedal three times
within five seconds.
If the CHANGE ENGINE OIL SOON
message is not on, the system is
reset.
The system is reset when the
CHANGE ENGINE OIL SOON message
is off.
If the CHANGE ENGINE OIL SOON
message comes back on when the
vehicle is started, the engine oil life
system has not been reset. Repeat the
procedure.
Automatic Transmission
Fluid
When to Check and Change
Automatic Transmission Fluid
If the vehicle has a diesel engine, see
the Duramax diesel supplement.
It is usually not necessary to check
the transmission fluid level. The only
reason for fluid loss is a transmission
leak or overheated transmission. This
vehicle is not equipped with a
transmission fluid level dipstick. There is a special procedure for
checking and changing the
transmission fluid in these vehicles.
Because this procedure is difficult,
this should be done at the dealer.
Contact the dealer for additional
information or the procedure can be
found in the service manual. See
Publication Ordering Information
0480.
Caution
Use of the incorrect automatic
transmission fluid may damage the
vehicle, and the damage may not be
covered by the vehicle warranty.
Always use the correct automatic
transmission fluid. See
Recommended Fluids and Lubricants
0464.
Change the fluid and filter at the
scheduled maintenance intervals
listed in Maintenance Schedule 0455.
Be sure to use the transmission fluid
listed in Recommended Fluids and
Lubricants 0464.

VEHICLE CARE 379
{Warning
An underhood electric fan can start
up even when the engine is not
running and can cause injury. Keep
hands, clothing, and tools away
from any underhood electric fan.
{Warning
Do not touch heater, radiator, a/c
pipes or hoses, or other engine
parts. They can be very hot and can
burn you. Do not run the engine if
there is a leak; all coolant could
leak out. That could cause an
engine fire and can burn you. Fix
any leak before driving the vehicle.
Engine Coolant
The cooling system in the vehicle is
filled with DEX-COOL engine coolant.
This coolant is designed to remain in
the vehicle for 5 years or 240 000 km
(150,000 mi), whichever occurs first.The following explains the cooling
system and how to check and add
coolant when it is low. If there is a
problem with engine overheating, see
Engine Overheating
0381.
What to Use
{Warning
Plain water, or other liquids such as
alcohol, can boil before the proper
coolant mixture will. With plain
water or the wrong mixture, the
engine could get too hot but there
would not be an overheat warning.
The engine could catch fire and you
or others could be burned.
Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
coolant. This mixture:
.Gives freezing protection down to
−37 °C (−34 °F), outside temperature.
.Gives boiling protection up to
129 °C (265 °F), engine temperature.
.Protects against rust and corrosion.
.Will not damage aluminum parts.
.Helps keep the proper engine
temperature.
Caution
Do not use anything other than a
mix of DEX-COOL coolant that
meets GM Standard GMW3420 and
clean, drinkable water. Anything
else can cause damage to the
engine cooling system and the
vehicle, which would not be covered
by the vehicle warranty.
Never dispose of engine coolant by
putting it in the trash, or by pouring it
on the ground, or into sewers,
streams, or bodies of water. Have the
coolant changed by an authorized
service center, familiar with legal
requirements regarding used coolant
disposal. This will help protect the
environment and your health.
Checking Coolant
The coolant surge tank is in the
engine compartment on the driver
side of the vehicle. See Engine
Compartment Overview 0372.
The vehicle must be on a level surface
when checking the coolant level.

Cadillac Escalade Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
15567102) - 2022 - CRC - 11/17/21
380 VEHICLE CARE
Check to see if coolant is visible in the
coolant surge tank. If the coolant
inside the coolant surge tank is
boiling, wait until it cools down. The
coolant level should be at or above the
indicated mark. If it is not, there may
be a leak in the cooling system.
If coolant is visible but the coolant
level is not at or above the indicated
mark, see the following sections on
how to add coolant to the coolant
surge tank following.
How to Add Coolant to the
Coolant Surge Tank
If the vehicle has a diesel engine, see
“Cooling System”in the Duramax
diesel supplement for the proper
coolant fill procedure.
{Warning
Spilling coolant on hot engine parts
can burn you. Coolant contains
ethylene glycol and it will burn if
the engine parts are hot enough.
{Warning
Plain water, or other liquids such as
alcohol, can boil before the proper
coolant mixture will. With plain
water or the wrong mixture, the
engine could get too hot but there
would not be an overheat warning.
The engine could catch fire and you
or others could be burned.
{Warning
Steam and scalding liquids from a
hot cooling system are under
pressure. Turning the pressure cap,
even a little, can cause them to
come out at high speed and you
could be burned. Never turn the cap
when the cooling system, including
the pressure cap, is hot. Wait for
the cooling system and pressure
cap to cool.
Caution
Failure to follow the specific
coolant fill procedure could cause
the engine to overheat and could
cause system damage. If coolant is
not visible in the surge tank,
contact your dealer.
If no coolant is visible in the surge
tank, add coolant.

VEHICLE CARE 381
1. Remove the coolant surge tankpressure cap when the cooling
system, including the coolant surge
tank pressure cap and upper
radiator hose, is no longer hot.
Turn the pressure cap slowly
counterclockwise about one full
turn. If a hiss is heard, wait for that
to stop. A hiss means there is still
some pressure left.
2. Keep turning the pressure cap slowly, and remove it.
3. Fill the coolant surge tank with the proper mixture to the full
cold mark.
4. With the coolant surge tank pressure cap off, start the engine
and let it run until the engine
coolant temperature gauge
indicates approximately 90 °C
(195 °F). By this time, the coolant level
inside the coolant surge tank may
be lower. If the level is lower, add
more of the proper mixture to the
coolant surge tank until the level
reaches the indicated mark.
5. Replace the pressure cap tightly.
6. Verify coolant level after the engine is shut off and the coolant is cold.
If necessary, repeat coolant fill
procedure Steps 1–6.
Caution
If the pressure cap is not tightly
installed, coolant loss and engine
damage may occur. Be sure the cap
is properly and tightly secured.
Engine Overheating
If the vehicle has a diesel engine, see
the Duramax diesel supplement.
Caution
Do not run the engine if there is a
leak in the engine cooling system.
This can cause a loss of all coolant
(Continued)
Caution (Continued)
and can damage the system and
vehicle. Have any leaks fixed
right away.
The vehicle has several indicators to
warn of engine overheating.
There is a coolant temperature gauge
and an engine coolant temperature
warning light in the vehicle's
instrument cluster. See Engine Coolant
Temperature Gauge 0118 and
Engine Coolant Temperature Warning
Light 0129.
In addition, there are ENGINE
OVERHEATED STOP ENGINE,
ENGINE OVERHEATED IDLE ENGINE,
and ENGINE POWER IS REDUCED
messages in the Driver Information
Center (DIC).
If the decision is made not to lift the
hood when this warning appears, get
service help right away. See Roadside
Service 0475.
If the decision is made to lift the
hood, make sure the vehicle is parked
on a level surface.

Check to see if the engine cooling
fan(s) are running. If the engine is
overheating, the fans should be
running. If they are not, do not
continue to run the engine. Have the
vehicle serviced.
If Steam is Coming from the
Engine Compartment
{Warning
Steam and scalding liquids from a
hot cooling system are under
pressure. Turning the pressure cap,
even a little, can cause them to
come out at high speed and you
could be burned. Never turn the cap
when the cooling system, including
the pressure cap, is hot. Wait for
the cooling system and pressure
cap to cool.
If No Steam is Coming from the
Engine Compartment
The ENGINE OVERHEATED STOP
ENGINE or the ENGINE
OVERHEATED IDLE ENGINE message,
along with a low coolant condition,
can indicate a serious problem.If there is an engine overheat warning,
but no steam is seen or heard, the
problem may not be too serious.
Sometimes the engine can get a little
too hot when the vehicle:
.Climbs a long hill on a hot day.
.Stops after high-speed driving.
.Idles for long periods in traffic.
.Tows a trailer; see
Trailer Towing
0 340.
If the ENGINE OVERHEATED STOP
ENGINE or the ENGINE
OVERHEATED IDLE ENGINE message
appears with no sign of steam, try this
for a minute or so: 1. Turn the air conditioning off.
2. Turn the heater on to the highest temperature and to the highest fan
speed. Open the windows as
necessary.
3. When it is safe to do so, pull off the road, shift to P (Park) or
N (Neutral), and let the engine idle.
If the engine coolant temperature
gauge is no longer in the overheat
zone or an overheat warning no longer
displays, the vehicle can be driven.
Continue to drive the vehicle slowly for about 10 minutes. Keep a safe
vehicle distance from the vehicle in
front. If the warning does not come
back on, continue to drive normally
and have the cooling system checked
for proper fill and function.
If the warning continues, pull over,
stop, and park the vehicle right away.
If there is still no sign of steam and
the vehicle is equipped with 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 five minutes while
the vehicle is parked. If the warning is
still there, turn off the engine and get
everyone out of the vehicle until it
cools down.
If there is no sign of steam, idle the
engine for five minutes while parked.
If the warning is still displayed, turn
off the engine until it cools down.
Engine Fan
If the vehicle has a diesel engine, see
the Duramax diesel supplement.
