Maintenance When Trailer
Towing
The vehicle needs service
more often when used to tow
trailers. See Maintenance
Schedule0454. It is especially
important to check the engine
oil, axle lubricant, belts, cooling
system, and brake system
before and during each trip.
Check periodically that all nuts
and bolts on the trailer hitch
are tight.
Engine Cooling When
Trailer Towing
The cooling system may
temporarily overheat during
severe operating conditions.
See Engine Overheating 0381.
Trailer Towing
Caution
Towing a trailer improperly
can damage the vehicle and
result in costly repairs not
covered by the vehicle
warranty. To tow a trailer
correctly, follow the
directions in this section and
see your dealer for
important information about
towing a trailer with the
vehicle.
Trailer Weight
{Warning
Never exceed the towing
capacity for your vehicle. Safe trailering requires
monitoring the weight, speed,
altitude, road grades, outside
temperature, dimensions of
the front of the trailer, and
how frequently the vehicle is
used to tow a trailer.
Trailer Weight Ratings
When towing a trailer, the
combined weight of the
vehicle, vehicle contents,
trailer, and trailer contents
must be below all of the
maximum weight ratings for
the vehicle including:

Engine Oil
To ensure proper engine
performance and long life,
careful attention must be paid
to engine oil. Following these
simple, but important steps
will help protect your
investment:
.Use engine oil approved to
the proper specification and
of the proper viscosity
grade. See “Selecting the
Right Engine Oil” in this
section.
.Check the engine oil level
regularly and maintain the
proper oil level. See
“Checking Engine Oil” and
“When to Add Engine Oil” in
this section.
.Change the engine oil at the
appropriate time. See Engine
Oil Life System 0373.
.Always dispose of engine oil
properly. See “What to Do
with Used Oil” in this section.
Checking Engine Oil
Check the engine oil level
regularly, every 650 km
(400 mi), especially prior to a
long trip. The engine oil
dipstick handle is a loop. See
Engine Compartment
Overview0367 for the
location.
{Warning
The engine oil dipstick
handle may be hot; it could
burn you. Use a towel or
glove to touch the dipstick
handle.
If a low oil Driver Information
Center (DIC) message displays,
check the oil level.
Follow these guidelines:
.To get an accurate reading,
park the vehicle on level
ground. Check the engine oil
level after the engine has
been off for at least two
hours. Checking the engine
oil level on steep grades or
too soon after engine
shutoff can result in
incorrect readings. Accuracy
improves when checking a
cold engine prior to starting.
Remove the dipstick and
check the level.
.If unable to wait two hours,
the engine must be off for at
least 15 minutes if the

Cadillac XT6 Owner Manual (GMNA-Localizing-U.S./Canada-16405819) -
2023 - CRC - 3/22/22
Vehicle Care 371
engine is warm, or at least
30 minutes if the engine is
not warm. Pull out the
dipstick, wipe it with a clean
paper towel or cloth, then
push it back in all the way.
Remove it again, keeping the
tip down, and check the
level.
When to Add Engine Oil
2.0L L4 Turbo Engine
3.6L V6 Engine
If the oil is below the
cross-hatched area at the tip
of the dipstick and the engine has been off for at least
15 minutes, add 1 L (1 qt) of the
recommended oil and then
recheck the level. See
“Selecting the Right Engine
Oil”
later in this section for an
explanation of what kind of oil
to use. For engine oil
crankcase capacity, see
Capacities and Specifications
0 463.
Caution
Do not add too much oil. Oil
levels above or below the
acceptable operating range
shown on the dipstick are
harmful to the engine. If the
oil level is above the
operating range (i.e., the
engine has so much oil that
the oil level gets above the
cross-hatched area that
shows the proper operating
range), the engine could be
damaged. Drain the excess
oil or limit driving of the
(Continued)
Caution (Continued)
vehicle, and seek a service
professional to remove the
excess oil.
See Engine Compartment
Overview 0367 for the
location of the engine oil
fill cap.
Add enough oil to put the level
somewhere in the proper
operating range. Push the
dipstick all the way back in
when finished.
Selecting the Right
Engine Oil
Selecting the right engine oil
depends on both the proper
oil specification and viscosity
grade. See Recommended
Fluids and Lubricants 0458.
Specification
Use full synthetic engine oils
that meet the dexos1
specification. Engine oils that
have been approved by GM as
meeting the dexos1

Engine Oil Life
System
When to Change
Engine Oil
This vehicle has a computer
system that indicates when to
change the engine oil and
filter. This is based on a
combination of factors which
include engine revolutions,
engine temperature, and miles
driven. Based on driving
conditions, the mileage at
which an oil change is
indicated can vary
considerably. For the oil life
system to work properly, the
system must be reset every
time the oil is changed.
When the system has
calculated that oil life has been
diminished, it indicates that an
oil change is necessary.
A CHANGE ENGINE OIL
SOON message comes on.
Change the oil as soon as
possible within the next
1 000 km (600 mi). It ispossible that, if driving under
the best conditions, the oil life
system might indicate that an
oil change is not necessary for
up to a year. The engine oil
and filter must be changed at
least once a year and at this
time the system must be
reset. Your dealer has trained
service people who will
perform this work and reset
the system. It is also important
to check the oil regularly over
the course of an oil drain
interval and keep it at the
proper level.
If the system is ever reset
accidentally, the oil must be
changed at 5 000 km
(3,000 mi) since the last oil
change. Remember to reset
the oil life system whenever
the oil is changed.
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 DIC controls on the right side of the
steering wheel, display
REMAINING OIL LIFE on
the DIC. See Driver
Information Center (DIC)
0144. When remaining oil
life is low, the CHANGE
ENGINE OIL SOON
message will appear on the
display.
2. Press the thumbwheel on the DIC controls and hold
down for a few seconds 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.
