260 DRIVING AND OPERATING
Be sure to read and follow the
instructions for the trailer brakes so
they are installed, adjusted, and
maintained properly.
Do not tap into the vehicle's hydraulic
system.
Since the vehicle is equipped with
StabiliTrak, the trailer brakes cannot
tap into the vehicle's hydraulic
system.
Trailer Wiring Harness
The seven-pin trailer connector is
mounted in the bumper. This
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/Grey: Left Stop/Turn Signal
. Green/Violet: Right Stop/Turn
Signal .
Grey/Brown: Taillamps
. White: Ground
. White/Green: Back-up Lamps

To help charge a remote (non-vehicle)
battery, press the Tow/Haul Mode
button at the end of the shift lever.
If the trailer is too light for Tow/Haul
Mode, turn on the headlamps to help
charge the battery.Electric Brake Control Wiring
Provisions
These wiring provisions are included
with the vehicle as part of the trailer
wiring package. These provisions are
for an electric brake controller.
The harness should be installed by
your dealer or a qualified service
center.
Trailer Sway Control (TSC)
Vehicles with StabiliTrak have a
Trailer Sway Control (TSC) feature.
Trailer sway is unintended side-to-side
motion of a trailer while being towed. If the vehicle is towing a trailer and
the TSC detects that sway is
increasing, the vehicle brakes are
selectively applied at each wheel, to
help reduce excessive trailer sway.
If TSC is enabled, the Traction Control
System (TCS)/StabiliTrak warning
light will flash on the instrument
cluster. Vehicle speed must be
reduced. If trailer sway continues,
StabiliTrak can reduce engine torque
to help slow the vehicle. See
Traction
Control/Electronic Stability Control
0 218.
{Warning
Even if the vehicle is equipped with
TSC, trailer sway could result in
loss of control and the vehicle could
crash. If excessive trailer sway is
detected, slow down to a safe speed.
Check the trailer and vehicle to help
correct possible causes. These could
include an improperly or overloaded
trailer, unrestrained cargo, improper
trailer hitch configuration, excessive

covered by the vehicle warranty.
Always use the automatic
transmission fluid listed in
Recommended Fluids and Lubricants
0355.
Change the fluid and filter at the
scheduled maintenance intervals
listed in Maintenance Schedule 0347.
Be sure to use the transmission fluid
listed in Recommended Fluids and
Lubricants 0355.
Engine Air Cleaner/Filter
See Engine Compartment Overview
0 267 for the location of the engine
air cleaner/filter.
When to Inspect the Engine Air
Cleaner/Filter
For intervals on changing and
inspecting the engine air cleaner/filter
see Maintenance Schedule 0347.
How to Inspect the Engine Air
Cleaner/Filter
Do not start the engine or have the
engine running with the engine air
cleaner/filter housing open. Before
removing the engine air cleaner/filter,
make sure that the engine air cleaner/
filter housing and nearby components
are free of dirt and debris. Remove the

VEHICLE CARE 279
{Warning
The brake wear warning sound
means that soon the brakes will not
work well. That could lead to a
crash. When the brake wear
warning sound is heard, have the
vehicle serviced.
Caution
Continuing to drive with worn-out
brake pads could result in costly
brake repair.
Some driving conditions or climates
can cause a brake squeal when the
brakes are first applied or lightly
applied. This does not mean
something is wrong with the brakes.
Properly torqued wheel nuts are
necessary to help prevent brake
pulsation. When tires are rotated, inspect brake pads for wear and
evenly tighten wheel nuts in the
proper sequence to torque
specifications. See
Capacities and
Specifications 0359.
Brake pads should be replaced as
complete sets.
Brake Pedal Travel
See your dealer if the brake pedal does
not return to normal height, or if
there is a rapid increase in pedal
travel. This could be a sign that brake
service may be required.
Replacing Brake System Parts
Always replace brake system parts
with new, approved replacement parts.
If this is not done, the brakes may not
work properly. The braking
performance expected can change in
many other ways if the wrong
replacement brake parts are installed
or if parts are improperly installed.
Brake Fluid
The brake master cylinder reservoir is
filled with GM approved DOT 3 brake
fluid as indicated on the reservoir cap.
See Engine Compartment Overview
0 267 for the location of the reservoir.
Checking Brake Fluid
With the vehicle in P (Park) on a level
surface, the brake fluid level should be
between the minimum and maximum
marks on the brake fluid reservoir.
There are only two reasons why the
brake fluid level in the reservoir may
go down:
. Normal brake lining wear. When
new linings are installed, the fluid
level goes back up.

Cadillac Escalade Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
11349344) - 2018 - crc - 11/7/17
280 VEHICLE CARE
.A fluid leak in the brake hydraulic
system. Have the brake hydraulic
system fixed. With a leak, the
brakes will not work well.
Always clean the brake fluid reservoir
cap and the area around the cap
before removing it.
Do not top off the brake fluid. Adding
fluid does not correct a leak. If fluid is
added when the linings are worn,
there will be too much fluid when
new brake linings are installed. Add or
remove fluid, as necessary, only when
work is done on the brake hydraulic
system.
{Warning
If too much brake fluid is added, it
can spill on the engine and burn,
if the engine is hot enough. You or
others could be burned, and the
vehicle could be damaged. Add
brake fluid only when work is done
on the brake hydraulic system. When the brake fluid falls to a low
level, the brake warning light comes
on. See
Brake System Warning Light
0 138.
Brake fluid absorbs water over time
which degrades the effectiveness of
the brake fluid. Replace brake fluid at
the specified intervals to prevent
increased stopping distance. See
Maintenance Schedule 0347.
What to Add
Use only GM approved DOT 3 brake
fluid from a clean, sealed container.
See Recommended Fluids and
Lubricants 0355.
{Warning
The wrong or contaminated brake
fluid could result in damage to the
brake system. This could result in
the loss of braking leading to a
possible injury. Always use the
proper GM approved brake fluid.
Caution
If brake fluid is spilled on the
vehicle's painted surfaces, the paint
finish can be damaged. Immediately
wash off any painted surface.
Battery - North America
The original equipment battery is
maintenance free. Do not remove the
cap and do not add fluid.
Refer to the replacement number
shown on the original battery label
when a new battery is needed. See
Engine Compartment Overview 0267
for battery location.
{Warning
WARNING: Battery posts,
terminals, and related accessories
contain lead and lead compounds,
chemicals known to the State of
California to cause cancer and birth
defects or other reproductive harm.
