corresponding screen.
Lights
This view displays the names of the trailer
connector pins, a graphic of the trailer
connector, and a graphic of the back of the
trailer. Any connector pin that fails turns an amber
color, and the location of the corresponding
connection is highlighted on the graphic of
the back of the trailer.
If a trailer connection is detected without
any faults, the view displays
“No Issues
Found.”
When a trailer is connected, the Trailering
App System detects the trailer connection
using the Stop/Turn Signal lighting circuits
and alerts the driver by requesting a trailer
profile setup through the Trailering App
System on the infotainment screen. If a
default trailer profile is selected, the
Trailering App System does not display a
Trailer Detection Alert to the user when a
trailer is connected.
When a trailer is connected and the vehicle
is off, the Trailering App System periodically
pulses the lighting circuits of the trailer to
verify it is still connected. The trailer lights
may periodically flash as a result of this
trailer connection detection. These flashes
may be more visible in dark ambient light
environments. The flashing or flickering
lights are a normal condition and the
Trailering App System has built-in
protections to prevent the battery from draining. When Theft Alert is enabled, the
frequency and pattern of this flashing
changes.
If a connected trailer disconnects, a message
immediately appears on the DIC if the
vehicle is on, or the next time the vehicle is
turned on. Check your trailer connection if
needed.
Connection Problem
If any of the trailer connections are lost, a
message about the connection issue appears
on the DIC. The infotainment display also
shows the connection issue in the Lights
Status view.

Cooling System
It is not necessary to regularly check coolant
unless a leak is suspected or an unusual
noise is heard. A coolant loss could indicate
a problem. Have it inspected and repaired
by your dealer.
The following explains the cooling system
and how to check coolant level.
During vehicle operation and also during
charging, the high voltage battery cells in
the vehicle are kept within a normal
operating temperature range. If the
temperature rises above this temperature, the battery cooling system turns on the air
conditioning compressor and cools the
coolant until the correct temperature is
reached. If the temperature falls below this
temperature, a high voltage heater, located
outside the battery on a cradle, heats the
coolant until the correct temperature is
reached.
Checking Coolant
The coolant needs to be replaced at the
appropriate interval. See
Maintenance
Schedule 0389.
The coolant reservoir is in the underhood
compartment. See Underhood Compartment
Overview 0325.
To access the coolant reservoir under the
hood, the right side access cover needs to
be removed. 1. Park on a level surface and turn the vehicle off.
2. Open the hood. See Hood019.
3. Turn the three bolts three quarter turn
and remove the right side access cover.

Caution
Continuing to drive with worn-out brake
linings could result in costly brake
repairs.
Some driving conditions or climates can
cause a brake squeal when the brakes are
first applied, clearing up following several
applications. 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 linings for wear
and evenly tighten wheel nuts in the proper
sequence to torque specifications. See
Capacities and Specifications 0395.
Brake pads should 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 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 can
change in many ways if the wrong brake
parts are installed or if parts are improperly
installed.
Brake Fluid
The brake master cylinder reservoir is filled
with GM approved DOT 4 brake fluid as
indicated on the reservoir cap. See
Underhood Compartment Overview 0325 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.
.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.
When the brake fluid falls to a low level,
the brake warning light comes on. See Brake
System Warning Light 0115.
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 0389.
