death.. To help avoid injuries to you
and others, read and follow
all the instructions on the
fuel pump island.
. Turn off the engine when
refueling.
. Keep sparks, flames, and
smoking materials away
from fuel.

refueling.
(Continued)
Warning (Continued)
.Do not reenter the vehicle
while pumping fuel.
. Keep children away from the
fuel pump and never let
children pump fuel.
. Fuel can spray out if the
refueling nozzle is inserted
too quickly. This spray can
happen if the tank is nearly
full, and is more likely in hot
weather. Insert the refueling
nozzle slowly and wait for any
hiss noise to stop prior to
beginning to flow fuel.
If equipped, the fuel door is locked
when the vehicle doors are locked.

weight may reduce the trailering
capacity more than the total of the
additional weight.
It is important that the vehicle does
not exceed any of its ratings—
GCWR, GVWR, RGAWR, Maximum
Trailer Rating, or Tongue Weight. The
only way to be sure it is not exceeding
any of these ratings is to weigh the
vehicle and trailer.
Total Weight on the Vehicle's
Tires
Be sure the vehicle's tires are inflated
to the upper limit for cold tires. These
numbers can be found on the
Certification label or see Vehicle Load
Limits 0184. Make sure not to go over
the GVW limit for the vehicle, or the
GAWR, including the weight of the
trailer tongue. If using a
weight-distributing hitch, make sure
not to go over the rear axle limit
before applying the weight
distribution spring bars.
Towing Equipment
Hitches
It is important to have the correct
hitch equipment. Crosswinds, large
trucks going by, and rough roads are a
few reasons why the right hitch is
needed.
. The rear bumper on the vehicle is
not intended for hitches. Do not
attach rental hitches or other
bumper-type hitches to it. Use
only a frame-mounted hitch that
does not attach to the bumper.
. Will any holes be made in the
body of the vehicle when the
trailer hitch is installed? If there
are, then be sure to seal the holes
later when the hitch is removed.
If the holes are not sealed, dirt,
water, and deadly carbon
monoxide (CO) from the exhaust
can get into the vehicle. See Engine
Exhaust 0195. Hitch Cover
To remove the hitch cover,
if equipped:
1. Remove the two bolts on the lower tabs by turning
counterclockwise.
2. Lift the lower edge of the cover about 45 degrees.
3. Pull the cover downward to disengage the upper
attachments.

Cadillac XT5 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
11349110) - 2018 - CRC - 9/28/17
246 DRIVING AND OPERATING
To reinstall the hitch cover:1. Hold the cover at a 45 degree angle to the vehicle and push the
upper tabs in the hitch cover
into the slots in the fascia.
2. Move the bottom of the cover forward until the lower tabs line
up with the lower fascia slots.
3. Snap the hitch cover into place by pushing the upper corners
forward.
4. Reinstall the two bolts on the lower tabs by turning clockwise.
Safety Chains
Always attach chains between the
vehicle and the trailer. Cross the safety
chains under the tongue of the trailer
to help prevent the tongue from
contacting the road if it becomes
separated from the hitch. Always leave
just enough slack so the rig can turn.
Never allow safety chains to drag on
the ground.
Trailer Brakes
A loaded trailer that weighs more than
454 kg (1,000 lb) needs to have its own
brake system that is adequate for the
weight of the trailer. Be sure to read
and follow the instructions for the
trailer brakes so they are installed,
adjusted, and maintained properly.
Because the vehicle has antilock
brakes, do not tap into the vehicle's
brake system. If you do, both brake
systems will not work well, or at all.
Trailer Wiring Harness
Basic Trailer Wiring
The trailer wiring harness, with a
seven-pin connector, is located at the
rear of the vehicle and is tied to the
vehicle's frame. The harness connector
can be plugged into a seven-pin
universal heavy-duty trailer connector
available through your dealer.
Use only a round, seven-wire
connector with flat blade terminals
meeting SAE J2863 specifications for
proper electrical connectivity. The seven-wire harness contains the
following trailer circuits:
.
Yellow/Gray: Stop/Turn Signal Left
. Green/Violet: Stop/Turn Signal
Right
. Gray/Brown: Parking Lamps
. White/Green: Back-up Lamps
. Red/Green: Battery Feed
. Black: Ground
. Blue: Electric Brakes*
*The fuse for this circuit is installed in
the engine compartment fuse block,
but the wires are not connected. They
should be connected by your dealer or
a qualified service center.
If the back-up lamp circuit is not
functional, contact your dealer.

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 0256.
. 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 Overview 0253 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.

1. Turn the pressure cap slowlycounterclockwise. 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 withthe proper mixture to the mark
pointed to on the front of the
coolant surge tank.
4. With the coolant surge tank pressure cap off, start the engine
and let it run until you can feel
the upper radiator hose getting
hot. Watch out for the engine
cooling fans. 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 mark pointed to on the front
of the coolant surge tank.
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
Step 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
The vehicle has several indicators to
warn of the engine overheating.
There is an engine coolant
temperature gauge and an engine
coolant temperature warning light on
the instrument cluster. See Engine
Coolant Temperature Gauge 0129 and
Engine Coolant Temperature Warning
Light 0138. The vehicle may also
display a message on 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 0347.
If the decision is made to lift the
hood, make sure the vehicle is parked
on a level surface. Then check to see if
the engine cooling fan is running.
