IN BRIEF 29
{Danger
Improper use of portable electric
vehicle charge cords may cause a
fire, electrical shock, or burns, and
may result in damage to property,
serious injury, or death.. Do not use extension cords,
multi-outlet power strips,
splitters, grounding adaptors,
surge protectors, or similar
devices.
. Do not use an electrical outlet
that is worn or damaged,
or will not hold the plug
firmly in place.
. Do not use an electrical outlet
that is not properly grounded.
. Do not use an electrical outlet
that is on a circuit with other
electrical loads.
Charge Cord Status Indicators
See Charge Cord (PLUG-IN Only) 0279.
Charge Level Selection
Charge level selection can be made
using the Charge Limit Preference
screen on the infotainment display.
See “Charge Limit Selection ”under
Programmable Charging (PLUG-IN Only)
0 152.
{Warning
Using a charge level that exceeds
the electrical circuit or electrical
outlet capacity may start a fire or
damage the electrical circuit. Use
the lowest charge level until a
qualified electrician inspects the
electrical circuit capacity. Use the
lowest charge level if the electrical
circuit or electrical outlet capacity
is not known.
Regenerative Braking
Regenerative braking takes some of
the energy from the moving vehicle
and turns it back into electrical
energy. This energy is then stored in
the high voltage battery system, contributing to increased energy
efficiency. See
Regenerative Braking
(PLUG-IN Only) 0237.
Service
{Warning
Never try to do your own service on
high voltage components. You can
be injured and the vehicle can be
damaged if you try to do your own
service work. Service and repair of
these high voltage components
should only be performed by a
trained service technician with the
proper knowledge and tools. See
Doing Your Own Service Work 0298.

DRIVING AND OPERATING 213
{Warning
If the vehicle's tires spin at high
speed, they can explode, and you or
others could be injured. The vehicle
can overheat, causing an engine
compartment fire or other damage.
Spin the wheels as little as possible
and avoid going above 56 km/h
(35 mph).
Rocking the Vehicle to Get it Out
Turn the steering wheel left and right
to clear the area around the front
wheels. Turn off any traction system.
Shift back and forth between
R (Reverse) and a low forward gear,
spinning the wheels as little as
possible. To prevent transmission
wear, wait until the wheels stop
spinning before shifting gears. Release
the accelerator pedal while shifting,
and press lightly on the accelerator
pedal when the transmission is in
gear. Slowly spinning the wheels in
the forward and reverse directions
causes a rocking motion that could
free the vehicle. If that does not get
the vehicle out after a few tries, itmight need to be towed out. If the
vehicle does need to be towed out, see
Towing the Vehicle
0376.
Vehicle Load Limits
It is very important to know how
much weight the vehicle can carry.
This weight is called the vehicle
capacity weight and includes the
weight of all occupants, cargo, and
all nonfactory-installed options.
Two labels on the vehicle may
show how much weight it may
properly carry: the Tire and
Loading Information label and the
Certification label.
{Warning
Do not load the vehicle any
heavier than the Gross Vehicle
Weight Rating (GVWR),
or either the maximum front or
rear Gross Axle Weight Rating
(GAWR). This can cause
systems to break and change
(Continued)
Warning (Continued)
the way the vehicle handles.
This could cause loss of control
and a crash. Overloading can
also reduce stopping distance,
damage the tires, and shorten
the life of the vehicle.
Tire and Loading Information

Label Example
A vehicle-specific Tire and
Loading Information label is
attached to the vehicle's center

pillar (B-pillar). The Tire and
Loading Information label shows
the number of occupant seating
positions (1), and the maximum
vehicle capacity weight (2) in
kilograms and pounds.
The Tire and Loading Information
label also shows the tire size of
the original equipment tires (3)
and the recommended cold tire
inflation pressures (4). For more
information on tires and inflation
seeTires 0340 and Tire Pressure
0 347.
There is also important loading
information on the Certification
label. It may show the Gross
Vehicle Weight Rating (GVWR)
and the Gross Axle Weight Rating
(GAWR) for the front and rear
axle. See “Certification Label” later
in this section. “Steps for Determining Correct
Load Limit–
1.Locate the statement "The
combined weight of
occupants and cargo should
never exceed XXX kg or
XXX lbs." on your vehicle’s
placard.
2.Determine the combined
weight of the driver and
passengers that will be riding
in your vehicle.
3.Subtract the combined weight
of the driver and passengers
from XXX kg or XXX lbs.
4.The resulting figure equals
the available amount of cargo
and luggage load capacity. For
example, if the "XXX" amount
equals 1400 lbs. and there
will be five 150 lb passengers
in your vehicle, the amount
of available cargo and luggage
load capacity is 650 lbs.
(1400-750 (5 x 150) =
650 lbs.)
5.Determine the combined
weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely
exceed the available cargo
and luggage load capacity
calculated in Step 4.
6.If your vehicle will be towing
a trailer, load from your
trailer will be transferred to
your vehicle. Consult this
manual to determine how
this reduces the available
cargo and luggage load
capacity of your vehicle.”

348 VEHICLE CARE
Caution (Continued)
.Poor handling.
.Reduced fuel economy.
Overinflated tires, or tires that
have too much air, can result in:
.Unusual wear.
.Poor handling.
.Rough ride.
.Needless damage from
road hazards.
The Tire and Loading Information
label on the vehicle indicates the
original equipment tires and the
correct cold tire inflation
pressures. The recommended
pressure is the minimum air
pressure needed to support the
vehicle's maximum load carrying
capacity. See Vehicle Load Limits
0 213. How the vehicle is loaded affects
vehicle handling and ride comfort.
Never load the vehicle with more
weight than it was designed to
carry.
When to Check
Check the tires once a month or
more. Do not forget the compact
spare, if the vehicle has one. The
cold compact spare tire pressure
should be at 420 kPa (60 psi). See
Compact Spare Tire
0373.
How to Check
Use a good quality pocket-type
gauge to check tire pressure.
Proper tire inflation cannot be
determined by looking at the tire.
Check the tire inflation pressure
when the tires are cold, meaning
the vehicle has not been driven for
at least three hours or no more
than 1.6 km (1 mi).
Remove the valve cap from the
tire valve stem. Press the tire
gauge firmly onto the valve to get
a pressure measurement. If the cold tire inflation pressure
matches the recommended
pressure on the Tire and Loading
Information label, no further
adjustment is necessary. If the
inflation pressure is low, add air
until the recommended pressure is
reached. If the inflation pressure
is high, press on the metal stem in
the center of the tire valve to
release air.
Recheck the tire pressure with the
tire gauge.
Put the valve caps back on the
valve stems to keep out dirt and
moisture and prevent leaks. Use
only valve caps designed for the
vehicle by GM. TPMS sensors
could be damaged and would not
be covered by the vehicle
warranty.

VEHICLE CARE 359
Wheel Alignment and Tire
Balance
The tires and wheels were aligned and
balanced at the factory to provide the
longest tire life and best overall
performance. Adjustments to wheel
alignment and tire balancing are not
necessary on a regular basis. Consider
an alignment check if there is unusual
tire wear or the vehicle is significantly
pulling to one side or the other. Some
slight pull to the left or right,
depending on the crown of the road
and/or other road surface variations
such as troughs or ruts, is normal.
If the vehicle is vibrating when driving
on a smooth road, the tires and
wheels may need to be rebalanced.
See your dealer for proper diagnosis.
Wheel Replacement
Replace any wheel that is bent,
cracked, or badly rusted or corroded.
If wheel nuts keep coming loose, the
wheel, wheel bolts, and wheel nuts
should be replaced. If the wheel leaks
air, replace it. Some aluminum wheels
can be repaired. See your dealer if any
of these conditions exist.Your dealer will know the kind of
wheel that is needed.
Each new wheel should have the same
load-carrying capacity, diameter,
width, offset, and be mounted the
same way as the one it replaces.
Replace wheels, wheel bolts, wheel
nuts, or Tire Pressure Monitor System
(TPMS) sensors with new GM original
equipment parts.
{Warning
Using the wrong replacement
wheels, wheel bolts, or wheel nuts
can be dangerous. It could affect
the braking and handling of the
vehicle. Tires can lose air, and
cause loss of control, causing a
crash. Always use the correct wheel,
wheel bolts, and wheel nuts for
replacement.
Caution
The wrong wheel can also cause
problems with bearing life, brake
cooling, speedometer or odometer
calibration, headlamp aim, bumper
height, vehicle ground clearance,
and tire or tire chain clearance to
the body and chassis.
Used Replacement Wheels
{Warning
Replacing a wheel with a used one
is dangerous. How it has been used
or how far it has been driven may
be unknown. It could fail suddenly
and cause a crash. When replacing
wheels, use a new GM original
equipment wheel.
