Vehicle Care 257
Caution
After driving in the overheated
engine protection operating
mode, the engine oil will be
severely degraded. Any repairs
performed before the engine is
cool may cause engine damage.
Allow the engine to cool before
attempting any repair. Repair the
cause of coolant loss, change the
oil, and reset the oil life system.
SeeEngine Oil 0246.
Power Steering Fluid
The power steering fluid reservoir is
under the engine cover on the
passenger side of the vehicle. See
Engine Compartment Overview
0245 for reservoir location.
When to Check Power Steering
Fluid
It is not necessary to regularly
check power steering fluid unless
you suspect there is a leak in the
system or you hear an unusual
noise. 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. Remove the engine cover. See Engine Cover 0246.
3. Wipe the cap and the top of the reservoir clean.
4. Unscrew the cap and wipe the dipstick with a clean rag.
5. Replace the cap and completely tighten it.
6. Remove the cap again and look at the fluid level on the
dipstick. The fluid level should be
somewhere between the MAX and
MIN line on the dipstick in room
temperature. If the fluid is on or
below the MIN line, add fluid close
to the MAX line.
What to Use
To determine what kind of fluid to
use, see
Recommended Fluids and
Lubricants 0330. Always use the
proper fluid.
Caution
Use of the incorrect fluid may
damage the vehicle and the
damages may not be covered by
the vehicle warranty. Always use
the correct fluid listed in
Recommended Fluids and
Lubricants 0330.
Washer Fluid
What to Use
When adding windshield washer
fluid, be sure to read the
manufacturer's instructions before

GMC Acadia/Acadia Denali Owner Manual (GMNA-Localizing-U.S./Canada/
Mexico-9159268) - 2016 - crc - 7/31/15
258 Vehicle Care
use. If the vehicle will be operating
in an area where the temperature
may fall below freezing, use a fluid
that has sufficient protection against
freezing.
Adding Washer Fluid
When the windshield washer fluid
reservoir is low, a WASHER FLUID
LOW ADD FLUID message will be
displayed on the Driver Information
Center (DIC). SeeWasher Fluid
Messages 0139.
Open the cap with the washer
symbol on it. Add washer fluid until
the tank is full. See Engine
Compartment Overview 0245 for
reservoir location.
Caution
. Do not use washer fluid that
contains any type of water
repellent coating. This can
cause the wiper blades to
chatter or skip.
. Do not use engine coolant
(antifreeze) in the
windshield washer. It can
damage the windshield
washer system and paint.
. 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.
. When using concentrated
washer fluid, follow the
manufacturer instructions for
adding water.
. Fill the washer fluid tank
only three-quarters full when
it is very cold. This allows
for fluid expansion if
(Continued)
Caution (Continued)
freezing occurs, which could
damage the tank if it is
completely full.
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 can
be heard all the time when the
vehicle is moving, except when
applying the brake pedal firmly.
{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.
