Driving and Operating 317
The vehicle can tow in
D (Drive). Shift the
transmission to a lower gear if
the transmission shifts too
often under heavy loads and/
or hilly conditions.
When towing at higher
altitudes, engine coolant will
boil at a lower temperature
than at lower altitudes. If the
engine is turned off
immediately after towing at
high altitude on steep uphill
grades, the vehicle could show
signs similar to engine
overheating. To avoid this, let
the engine run, preferably on
level ground, with the
transmission in P (Park) for a
few minutes before turning
the engine off. If the overheat
warning comes on, see Engine
Overheating0342.Parking on Hills
{Warning
To prevent serious injury or
death, always park your
vehicle and trailer on a level
surface when possible.
When parking your vehicle and
your trailer on a hill: 1. Press the brake pedal, but do not shift into P (Park)
yet. Turn the wheels into
the curb if facing downhill
or into traffic if facing
uphill.
2. Have someone place chocks under the trailer
wheels.
3. When the wheel chocks are in place, gradually
release the brake pedal to
allow the chocks to absorb
the load of the trailer.
4. Reapply the brake pedal. Then apply the parking
brake and shift into
P (Park). 5. Release the brake pedal.
Leaving After Parking on
a Hill
1. Apply and hold the brake
pedal.
.Start the engine.
.Shift into the
desired gear.
.Release the parking
brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the
chocks.

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 0335.
.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
Overview0331 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

Cadillac XT4 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
16412876) - 2023 - CRC - 3/25/22
Vehicle Care 333
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
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
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
0 433.
Caution
Do not add too much oil. Oil
levels above or below the
acceptable operating range
shown on the dipstick are
(Continued)
Caution (Continued)
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
vehicle, and seek a service
professional to remove the
excess oil.
See Engine Compartment
Overview 0331 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 through.

bodies of water. Recycle it by
taking it to a place that
collects used oil.
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 OILSOON message comes on.
Change the oil as soon as
possible within the next
1 000 km (600 mi). It is
possible that, if driving under
the best conditions, the oil life
system may 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)
0136. When remaining oil
life is low, the CHANGE
ENGINE OIL SOON
message will appear on the
display.
2. Press
Von 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.
