Driving and Operating 181
Aamber if the vehicle crosses a
detected lane marking. Additionally, there
may be three beeps, or the driver seat may
pulse three times, on the right or left,
depending on the lane departure direction.
Take Steering
The LKA system does not continuously steer
the vehicle. If LKA does not detect active
driver steering, an alert and chime may be
provided. Steer the vehicle to dismiss. LKA
may become temporarily unavailable after
repeated take steering alerts.
When the System Does Not Seem to
Work Properly
The system performance may be
affected by:
.Close vehicles ahead.
.Sudden lighting changes, such as when
driving through tunnels.
.Banked roads.
.Roads with poor lane markings, such as
two-lane roads.
If the LKA system is not functioning
properly when lane markings are clearly
visible, cleaning the windshield may help. A camera blocked message may display if
the camera is blocked. Some driver
assistance systems may have reduced
performance or not work at all. An LKA or
LDW unavailable message may display if the
systems are temporarily unavailable. This
message could be due to a blocked camera.
The LKA system does not need service. Clean
the outside of the windshield behind the
rearview mirror.
LKA assistance and/or LDW alerts may occur
due to tar marks, shadows, cracks in the
road, temporary or construction lane
markings, or other road imperfections. This
is normal system operation; the vehicle does
not need service. Turn LKA off if these
conditions continue.
Charging
When to Charge
When the high voltage battery is getting
low, charging messages may display.
The CHARGE VEHICLE SOON message
indicates that the driving range is low and
the vehicle needs to be charged soon. As the
charge level drops, the PROPULSION POWER
IS REDUCED message is displayed and the
accelerator pedal response is reduced. Inaddition, the remaining range value will
change to LOW indicating the vehicle should
be charged immediately.
When the energy is fully depleted, the OUT
OF ENERGY, CHARGE VEHICLE NOW message
displays and the vehicle slows to a stop.
Brake and steering assist will still operate.
Once the vehicle has stopped, turn the
vehicle off. See
Propulsion Power Messages
0 100.
Plug-In Charging
This section explains the process for
charging the high voltage battery. Do not
allow the vehicle to remain in temperature
extremes for long periods without being
driven or plugged in. Plug the vehicle in
when temperatures are below 0 °C (32 °F)
and above 32 °C (90 °F) to maximize high
voltage battery life.
Charge times will vary based on battery
condition, charge level, and outside
temperature. See Programmable Charging
0 90 for charge mode selection.
If equipped, the vehicle can be charged
using DC charging equipment typically found
at service stations and other public
locations.

Electrical Outlet/Plug Fault: The charge cord has detected that the
electrical outlet/plug overheated. Electrical outlets may wear out with
normal usage or may be damaged over time, making them unsuitable for
electric vehicle charging. Do not use an electrical outlet that is worn,
damaged, or one that will not hold the plug firmly in place. Use another
electrical outlet or have the electrical outlet serviced by a qualified
electrician. Reset the charge cord by unplugging the charge cord from the
electrical outlet and re-plugging it.

Electrical System Fault: The charge cord has detected a missing or
improper ground within the building's electrical system. Do not use an
electrical outlet that is not properly grounded. Use another electrical outlet
or have a qualified electrician inspect and verify the building's electrical
system.

Vehicle Fault: The charge cord ground-fault circuit interrupter (GFCI) has
tripped. Ensure that there is no physical damage to the charge cord, and
that the vehicle plug is seated completely and making a good connection.
Reset the charge cord by unplugging it from the electrical outlet and
re-plugging it. If the fault remains, see an authorized dealer for service.

Conversions and Add-Ons
Add-On Electrical Equipment
{Warning
The Data Link Connector (DLC) is used for
vehicle service and Emission Inspection/
Maintenance testing. SeeService Vehicle
Soon Light 085. A device connected to
the DLC —such as an aftermarket fleet
or driver-behavior tracking device —may
interfere with vehicle systems. This could
affect vehicle operation and cause a
crash. Such devices may also access
information stored in the vehicle’s
systems.
Caution
Some electrical equipment can damage
the vehicle or cause components to not
work and would not be covered by the
vehicle warranty. Always check with your
dealer before adding electrical equipment.
Add-on equipment can drain the vehicle's
12-volt battery, even if the vehicle is not
operating. When adding electrical equipment, it should
only be connected using the accessory
power outlets. The maximum power that
can be supplied by one accessory power
outlet or spread across all three is 200 watts
or 15 amps. Exceeding 200 watts or 15 amps
may cause erratic vehicle operation.
The vehicle has an airbag system. Before
attempting to add anything electrical to the
vehicle, see
Servicing the Airbag-Equipped
Vehicle 047 and
Adding Equipment to the Airbag-Equipped
Vehicle 047.

{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
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 0262.
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 0200
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 085.

Halogen Bulbs
{Warning
Halogen bulbs have pressurized gas inside
and can burst if you drop or scratch the
bulb. You or others could be injured. Be
sure to read and follow the instructions
on the bulb package.
High Intensity Discharge (HID)
Lighting
{Warning
The High Intensity Discharge (HID)
lighting system operates at a very high
voltage. If you try to service any of the
system components, you could be
seriously injured. Have your dealer or a
qualified technician service them.
This vehicle has several HID lamps.
For replacement of any HID lighting
assembly, contact your dealer.
After an HID headlamp bulb has been
replaced, the beam might be a slightly
different shade than it was originally. This is
normal.
LED Lighting
This vehicle has several LED lamps.
For replacement of any LED lighting
assembly, contact your dealer.
Taillamps, Turn Signal, Stoplamps,
and Back-Up Lamps
1. Back-up Lamp
2. Turn Signal Lamp

To access the bulbs, reach up behind the
rear bumper. To replace a back-up bulb, turn
signal lamp, taillamp, or stoplamp: 1. Turn the bulb socket counterclockwise
and remove it from the socket. The
lamps are in the rear bumper.
2. Press the new bulb in and turn clockwise to install the bulb into the socket.
3. Turn the bulb socket clockwise to reinstall.
