Vehicle Care 10-23Under heavy vehicle loading,
trailer towing, and/or high outside
temperatures, or if operating the
air conditioning system, the fans
can change to high speed and an
increase in fan noise might be
heard. This is normal and indicates
that the cooling system is
functioning properly. The fans
change to low speed when
additional cooling is no longer
required.
Power Steering Fluid
See Engine Compartment Overview
on page 10 ‑ 6 for reservoir location. When to Check Power Steering
Fluid It is not necessary to regularly
check power steering fluid unless
there is a leak suspected in the
system or an unusual noise is
heard. A fluid loss in this system
could indicate a problem. Have the
system inspected and repaired.
How to Check Power Steering
Fluid To check the power steering fluid:
1. Turn the key off and let the
engine compartment cool down.
2. Wipe the cap and the top of the
reservoir clean.
3. Unscrew the cap and wipe the
dipstick with a clean rag.
4. Replace the cap and completely
tighten it.
5. Remove the cap again and look
at the fluid level on the dipstick. The level should be at the FULL
COLD mark. If necessary, add only
enough fluid to bring the level up to
the mark.
What to Use To determine what kind of fluid to
use, see Recommended Fluids and
Lubricants on page 11 ‑ 7 . Always
use the proper fluid.
Notice: Use of the incorrect fluid
may damage the vehicle and the
damages may not be covered by
the vehicle's warranty. Always
use the correct fluid listed in
Recommended Fluids and
Lubricants on page 11 ‑ 7 .

10-24 Vehicle Care
Washer Fluid What to Use When windshield washer fluid needs
to be added, be sure to read the
manufacturer's instructions before
use. Use a fluid that has sufficient
protection against freezing in an
area where the temperature may fall
below freezing.
Adding Washer Fluid The vehicle has a low washer fluid
message on the DIC that comes
on when the washer fluid is low.
The message is displayed for
15 seconds at the start of each
ignition cycle. When the WASHER
FLUID LOW ADD FLUID message
displays, washer fluid will need to
be added to the windshield washer
fluid reservoir. Open the cap with the washer
symbol on it. Add washer fluid
until the tank is full. See Engine
Compartment Overview on
page 10 ‑ 6 for reservoir location.
Notice .
When using concentrated
washer fluid, follow the
manufacturer's instructions
for adding water. .
Do not mix water with
ready-to-use washer fluid.
Water can cause the solution
to freeze and damage the
washer fluid tank and other
parts of the washer system.
Also, water does not clean as
well as washer fluid. .
Fill the washer fluid tank
only three-quarters full
when it is very cold. This
allows for fluid expansion
if freezing occurs, which
could damage the tank if it
is completely full. .
Do not use engine coolant
(antifreeze) in the windshield
washer. It can damage the
windshield washer system
and paint.
Brakes This vehicle has disc brakes. Disc
brake pads have built-in wear
indicators that make a high-pitched
warning sound when the brake pads
are worn and new pads are needed.
The sound can come and go or be
heard all the time the vehicle is
moving, except when applying the
brake pedal firmly.

Vehicle Care 10-25
{ WARNINGThe 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.
Notice: 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 in Capacities and
Specifications on page 12 ‑ 2 .
Brake linings should always be
replaced as complete axle 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 might be
required.
Brake Adjustment
Every time the brakes are applied,
with or without the vehicle moving,
the brakes adjust for wear. Replacing Brake System Parts The braking system on a vehicle is
complex. Its many parts have to be
of top quality and work well together
if the vehicle is to have really good
braking. The vehicle was designed
and tested with top-quality brake
parts. When parts of the braking
system are replaced, be sure to get
new, approved replacement parts.
If this is not done, the brakes might
not work properly. For example,
installing disc brake pads that are
wrong for the vehicle, can change
the balance between the front and
rear brakes — for the worse. The
braking performance expected can
change in many other ways if the
wrong replacement brake parts are
installed.

10-26 Vehicle Care
Brake Fluid
The brake master cylinder reservoir
is filled with DOT 3 brake fluid. See
Engine Compartment Overview on
page 10 ‑ 6 for the location of the
reservoir.
There are only two reasons why
the brake fluid level in the reservoir
might go down: .
The brake fluid level goes down
because of normal brake lining
wear. When new linings are
installed, the fluid level goes
back up. .
A fluid leak in the brake
hydraulic system can also cause
a low fluid level. Have the brake
hydraulic system fixed, since a
leak means that sooner or later
the brakes will not work well. 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 brake fluid,
as necessary, only when work is
done on the brake hydraulic system.
{ WARNINGIf 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. See “ Checking Brake
Fluid ” in this section.
When the brake fluid falls to a low
level, the brake warning light comes
on. See Brake System Warning
Light on page 5 ‑ 21 . Refer to the Maintenance Schedule
to determine when to check the
brake fluid. See Scheduled
Maintenance on page 11 ‑ 2 .
Checking Brake Fluid Check brake fluid by looking at the
brake fluid reservoir. See Engine
Compartment Overview on
page 10 ‑ 6 .
The fluid level should be above
MIN. If it is not, have the brake
hydraulic system checked to see if
there is a leak.
Page 429 of 548

Black plate (27,1)Cadillac Escalade/Escalade ESV Owner Manual - 2011
Vehicle Care 10-27After work is done on the brake
hydraulic system, make sure the
level is above the MIN but not over
the MAX mark.
What to Add
Use only new DOT 3 brake fluid
from a sealed container. See
Recommended Fluids and
Lubricants on page 11 ‑ 7 .
Always clean the brake fluid
reservoir cap and the area around
the cap before removing it. This
helps keep dirt from entering the
reservoir.
{ WARNING
With the wrong kind of fluid in
the brake hydraulic system, the
brakes might not work well. This
could cause a crash. Always use
the proper brake fluid. Notice .
Using the wrong fluid
can badly damage brake
hydraulic system parts. For
example, just a few drops
of mineral-based oil, such
as engine oil, in the brake
hydraulic system can
damage brake hydraulic
system parts so badly that
they will have to be replaced.
Do not let someone put in
the wrong kind of fluid. .
If brake fluid is spilled on the
vehicle's painted surfaces,
the paint finish can be
damaged. Be careful not
to spill brake fluid on the
vehicle. If you do, wash it off
immediately. Battery If the vehicle is a hybrid, see the
hybrid supplement for more
information.
Refer to the replacement number
on the original battery label when
a new battery is needed. See
Engine Compartment Overview on
page 10 ‑ 6 for battery location.
{ DANGERBattery posts, terminals, and
related accessories contain lead
and lead compounds, chemicals
known to the State of California to
cause cancer and reproductive
harm. Wash hands after handling.

surface. A. Drain Plug
B. Fill Plug
If the level is below the bottom of
the fill plug hole, located on the
transfer case, some lubricant will
need to be added. Add enough
lubricant to raise the level to the
bottom of the fill plug hole. Use
care not to overtighten the plug.

Front Axle When to Check and Change
Lubricant
It is not necessary to regularly
check front axle fluid unless there
is a leak suspected or an unusual
noise is heard. A fluid loss could
indicate a problem. Have it
inspected and repaired. How to Check Lubricant
To get an accurate reading, the
vehicle should be on a level
surface.
A. Fill Plug
B. Drain Plug .
When the differential is cold, add
enough lubricant to raise the
level from 0 mm (0 in) to 3.2 mm
(1/8 in) below the fill plug hole. .
When the differential is at
operating temperature (warm),
add enough lubricant to raise
the level to the bottom of the fill
plug hole.
What to Use

10-30 Vehicle Care All axle assemblies are filled by
volume of fluid during production.
They are not filled to reach a certain
level. When checking the fluid
level on any axle, variations in the
readings can be caused by factory
fill differences between the minimum
and the maximum fluid volume.
Also, if a vehicle has just been
driven before checking the fluid
level, it may appear lower than
normal because fluid has traveled
out along the axle tubes and has
not drained back to the sump
area. Therefore, a reading taken
five minutes after the vehicle has
been driven will appear to have a
lower fluid level than a vehicle that
has been stationary for an hour or
two. Remember that the rear axle
assembly must be supported to get
a true reading. How to Check Lubricant
To get an accurate reading, the
vehicle should be on a level
surface. .
For Two-Wheel-Drive vehicles,
the proper level is from 15 mm
to 40 mm (0.6 in to 1.6 in) below
the bottom of the filler plug hole,
located on the rear axle. Add
only enough fluid to reach the
proper level. .
For All-Wheel-Drive vehicles, the
proper level is from 1.0 mm to
19.0 mm (0.04 in to 0.75 in)
below the bottom of the filler
plug hole, located on the rear
axle. Add only enough fluid to
reach the proper level.
What to Use Refer to Recommended Fluids
and Lubricants on page 11 ‑ 7 to
determine what kind of lubricant
to use.
