brake pedal is released or brake
pedal pressure is quickly
decreased.
Hill Start Assist (HSA)
This vehicle has a Hill Start Assist
(HSA) feature, which may be useful
when the vehicle is stopped on a
grade. This feature is designed to
prevent the vehicle from rolling,
either forward or rearward, during
vehicle drive off. After the driver
completely stops and holds the
vehicle in a complete standstill on a
grade, HSA will be automatically
activated. During the transition
period between when the driver
releases the brake pedal and starts
to accelerate to drive off on a grade,
HSA holds the braking pressure to
ensure that there is no rolling. The
brakes will automatically release
when the accelerator pedal is
applied within the two‐second
window. It will not activate if the
vehicle is in a drive gear and facing
downhill or if the vehicle is facing
uphill and in R (Reverse).
Ride Control Systems
Traction Control
System (TCS)
The vehicle has a TCS that limits
wheel spin. This is especially useful
in slippery road conditions. The
system operates if it senses that
one or both of the front wheels are
spinning or beginning to lose
traction. On an All-Wheel-Drive
(AWD) vehicle, the system will
operate if it senses that any of the
wheels are spinning or beginning to
lose traction. When this happens,
the system brakes the spinning
wheel(s) and/or reduces engine
power to limit wheel spin.
The system may be heard or felt
while it is working, but this is
normal.The TCS/StabiliTrak light flashes
when the traction control system is
limiting wheel spin.
The TCS/StabiliTrak light comes on
and the appropriate message will be
displayed in the DIC if there is a
problem with the traction control
system. When the TCS/StabiliTrak
light is on, the system will not limit
wheel spin. Adjust your driving
accordingly. SeeTraction Control
System (TCS)/StabiliTrak
®Light on
page 5‑24.
TCS automatically comes on
whenever the vehicle is started. To
limit wheel spin, especially in
slippery road conditions, the system
should always be left on, but it may
be necessary to turn the system off
if the vehicle is stuck in sand, mud,
or snow and rocking the vehicle is

Automatic Braking
Automatic Braking applies the
brakes, even if the driver has not
applied the brakes, in many
imminent front-end crash situations
to help reduce crash damage.
It may even help avoid some
crashes at very low speeds.
Automatic Braking may slow the
vehicle to a complete stop to try to
avoid a potential crash. If this
happens, Automatic Braking will
hold the vehicle at a stop until the
brake pedal is pressed. A firm press
of the accelerator pedal will also
release Automatic Braking.
{WARNING
Automatic Braking may
automatically brake the vehicle in
situations where it may be
unnecessary. It could respond to
a turning vehicle ahead,
guardrails, signs, and other
non-moving objects. This could(Continued)
WARNING (CONTINUED)
be uncomfortable and startling. To
override Automatic Braking, firmly
press the accelerator pedal, if it is
safe to do so.
Automatic Braking can be disabled
or reduced through vehicle
personalization. See the “Auto
Collision Preparation” portion of
“Collision/Detection Systems” under
Vehicle Personalization on
page 5‑44.
Side Blind Zone
Alert (SBZA)
If available, the Side Blind Zone
Alert system is a lane-changing aid
that assists drivers with avoiding
crashes that occur with vehicles in
the side blind zone (or spot) areas.
{WARNING
SBZA does not detect vehicles
rapidly approaching outside of the
side blind zones, pedestrians,
bicyclists, or animals. Failure to
use proper care when changing
lanes may result in injury, death,
or vehicle damage. Before
making a lane change, always
check mirrors, glance over your
shoulder, and use the turn
signals.

WARNING (CONTINUED)
.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
Locate the fuel door. The fuel gauge
has an arrow to indicate the side of
the vehicle the fuel door is on. To
open the fuel door, push the
rearward center edge in and release
and it will open.
The vehicle has a capless refueling
system and does not have a fuel
cap. The filling nozzle must be fully
inserted and latched prior to startng
fuel flow.
Be careful not to spill fuel. Do not
top off or overfill the tank and wait a
few seconds before removing the
nozzle. After initial shutoff, do not
partially remove the nozzle to add
more fuel as this will result in fuel
spillage. Clean fuel from painted
surfaces as soon as possible. See
Exterior Care on page 10‑76.{WARNING
If a fire starts while you are
refueling, do not remove the
nozzle. Shut off the flow of fuel by
shutting off the pump or by
notifying the station attendant.
Leave the area immediately.
Filling the Tank With a Portable
Gas Can
If the vehicle runs out of fuel and
must be filled from a portable
gas can:
1. Locate the capless funnel adapter from under the carpet in
the trunk.
2. Insert and latch the funnel into the capless fuel system.

Driving and Operating 9-61
Before starting, check all trailer hitch
parts and attachments, safety
chains, electrical connectors, lamps,
tires and mirrors. If the trailer has
electric brakes, start the
combination moving and then apply
the trailer brake controller by hand
to be sure the brakes work.
During the trip, check occasionally
to be sure that the load is secure
and the lamps and any trailer
brakes still work.
Towing with a Stability Control
System
When towing, the sound of the
stability control system might be
heard. The system is reacting to the
vehicle movement caused by the
trailer, which mainly occurs during
cornering. This is normal when
towing heavier trailers.
Following Distance
Stay at least twice as far behind the
vehicle ahead as you would when
driving the vehicle without a trailer.This can help to avoid situations
that require heavy braking and
sudden turns.
Passing
More passing distance is needed
when towing a trailer. Because the
rig is longer, it is necessary to go
farther beyond the passed vehicle
before returning to the lane.
Backing Up
Hold the bottom of the steering
wheel with one hand. To move the
trailer to the left, move your hand to
the left. To move the trailer to the
right, move your hand to the right.
Always back up slowly and,
if possible, have someone
guide you.
Making Turns
Notice:
Making very sharp turns
while trailering could cause the
trailer to come in contact with the
vehicle. The vehicle could be
damaged. Avoid making very
sharp turns while trailering. When turning with a trailer, make
wider turns than normal so the
trailer will not strike soft shoulders,
curbs, road signs, trees or other
objects. Use the turn signal well in
advance and avoid jerky or sudden
maneuvers.
Turn Signals When Towing a
Trailer
The turn signal indicators on the
instrument cluster flash whenever
signaling a turn or lane change.
Properly hooked up, the trailer
lamps also flash, telling other
drivers the vehicle is turning,
changing lanes or stopping.
When towing a trailer, the arrows on
the instrument cluster flash for turns
even if the bulbs on the trailer are
burned out. Check occasionally to
be sure the trailer bulbs are still
working.

9-62 Driving and Operating
Driving on Grades
Reduce speed and shift to a lower
gear before starting down a long or
steep downgrade. If the
transmission is not shifted down, the
brakes might have to be used so
much that they would get hot and no
longer work well.
The vehicle can tow in D (Drive).
Use a lower gear if the transmission
shifts too often.
When towing at high altitude on
steep uphill grades, engine coolant
boils at a lower temperature than at
normal 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
while parked, 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 Overheating on page 10‑14.
Parking on Hills
{WARNING
Parking the vehicle on a hill with
the trailer attached can be
dangerous. If something goes
wrong, the rig could start to move.
People can be injured, and both
the vehicle and the trailer can be
damaged. When possible, always
park the rig on a flat surface.
If parking the rig 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, release the brake pedal
until the chocks absorb the load. 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 while you:
.Start the engine.
.Shift into a 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.
Maintenance When Trailer
Towing
The vehicle needs service more
often when pulling a trailer. See the
Maintenance Schedule on
page 11‑3. Things that are
especially important in trailer
operation are automatic

2. Remove the seven screws ontop of the engine air cleaner/filter
housing.
3. Lift the filter cover housing away from the engine.
4. Pull out the filter.
5. Inspect or replace the engine air cleaner/filter.
6. Reverse Steps 2–4 to reinstall the filter cover housing.
{WARNING
Operating the engine with the air
cleaner/filter off can cause you or
others to be burned. The air
cleaner not only cleans the air; it
helps to stop flames if the engine
backfires. Use caution when
working on the engine and do not
drive with the air cleaner/filter off.
Notice: If the air cleaner/filter is
off, dirt can easily get into the
engine, which could damage it.
Always have the air cleaner/filter
in place when you are driving.
Cooling System
The cooling system allows the
engine to maintain the correct
working temperature.
1. Electric Engine Cooling Fans (Out of View)
2. Coolant Surge Tank and Pressure Cap
{WARNING
An electric engine cooling fan
under the hood 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.
Black plate (14,1)Cadillac XTS Owner Manual - 2013 - 1st - 4/13/12
10-14 Vehicle Care
{WARNING
Steam and scalding liquids from a
hot cooling system can blow out
and burn you badly. Never turn
the cap when the cooling system,
including the surge tank pressure
cap, is hot. Wait for the cooling
system and surge tank pressure
cap to cool.
The coolant surge tank pressure
cap can be removed when the
cooling system, including the surge
tank pressure cap and upper
radiator hose, is no longer hot.1. Turn the pressure cap slowly
counterclockwise. 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 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. Notice:
If the pressure cap is not
tightly installed, coolant loss and
possible engine damage may
occur. Be sure the cap is properly
and tightly secured.
Engine Overheating
The vehicle has an engine coolant
temperature gauge and an engine
temperature light to warn of engine
overheating.
There are also engine hot
messages that may be displayed in
the Driver Information Center (DIC).
See Engine Cooling System
Messages on page 5‑36.
If the decision is made not to lift the
hood when one of these warnings
appears, but get service help right
away. See Roadside Service on
page 13‑5.
If the decision is made to lift the
hood, make sure the vehicle is
parked on a level surface.

Electrical System
Electrical System
Overload
The vehicle has fuses and circuit
breakers to protect against an
electrical system overload.
When the current electrical load is
too heavy, the circuit breaker opens
and closes, protecting the circuit
until the current load returns to
normal or the problem is fixed. This
greatly reduces the chance of circuit
overload and fire caused by
electrical problems.
Fuses and circuit breakers protect
power devices in the vehicle.
Replace a bad fuse with a new one
of the identical size and rating.
If there is a problem on the road and
a fuse needs to be replaced, the
same amperage fuse can be
borrowed. Choose some feature of
the vehicle that is not needed to use
and replace it as soon as possible.
Headlamp Wiring
An electrical overload may cause
the lamps to go on and off, or in
some cases to remain off. Have the
headlamp wiring checked right away
if the lamps go on and off or
remain off.
Windshield Wipers
If the wiper motor overheats due to
heavy snow or ice, the windshield
wipers will stop until the motor cools
and will then restart.
Although the circuit is protected
from electrical overload, overload
due to heavy snow or ice may
cause wiper linkage damage.
Always clear ice and heavy snow
from the windshield before using the
windshield wipers.
If the overload is caused by an
electrical problem and not snow or
ice, be sure to get it fixed.
