by your dealer. The high voltage cooling
system reservoirs have tamper- resistant
pressure caps. The coolant should only be
serviced by a qualified technician.
Engine Overheating
The vehicle has several indicators to warn of
engine overheating.
There is an engine coolant temperature
gauge on the instrument cluster. SeeEngine
Coolant Temperature Gauge 087. The
vehicle may also display a message on the
Driver Information Center (DIC).
If the decision is made not to lift the hatch
but to get service help right away, see
Roadside Assistance Program 0332.
If the decision is made to lift the hatch,
make sure the vehicle is parked on a level
surface.
Then check to see if the engine cooling fans
are running. There are two cooling fans
located in the front (one at each corner) and
two cooling fans in the rear (one on each
side of the engine). If the engine is
overheating, the fans should be running.
If they are not, do not continue to run the
engine, and have the vehicle serviced.
Caution
Do not run the engine if there is a leak
in the engine cooling system. This can
cause a loss of all coolant and can
damage the system and vehicle. Have
any leaks fixed right away.
If Steam Is Coming from the Engine
{Warning
Steam and scalding liquids from a hot
cooling system are under pressure.
Turning the pressure cap, even a little,
can cause them to come out at high
speed and you could be burned. Never
turn the cap when the cooling system,
including the pressure cap, is hot. Wait
for the cooling system and pressure cap
to cool.
If Steam Is Coming from the Engine
Compartment with no Overheat Warning
Water from rain and car washes could enter
the engine compartment and contact hot
surfaces. If steam is coming from the engine
compartment with no accompanying
overheat warning, no service is needed.
If No Steam Is Coming from the Engine
If an engine overheat warning is displayed
but no steam can be seen or heard, the
problem may not be too serious. Sometimes
the engine can get a little too hot when the
vehicle:
.Climbs a long hill on a hot day.
.Stops after high-speed driving.
.Idles for long periods in traffic.
If the overheat warning is displayed with no
sign of steam: 1. Turn the air conditioning off.
2. Turn the heater on to the highest temperature and to the highest fan
speed. Open the windows as necessary.
3. When it is safe to do so, pull off the road, shift to P (Park) or N (Neutral), and
let the engine idle.
If the engine coolant temperature gauge is
no longer in the shaded area or an overheat
warning no longer displays, the vehicle can
be driven. Continue to drive the vehicle
slowly for about 10 minutes. Keep a safe
vehicle distance from the vehicle in front.
If the warning does not come back on,

12-Volt Lithium-Ion Battery (E-Ray)
{Warning
WARNING:Battery posts, terminals and
related accessories can expose you to
chemicals including lead and lead
compounds, which are known to the
State of California to cause cancer and
birth defects or other reproductive harm.
Wash hands after handling. For more
information go to
www.P65Warnings.ca.gov.
See California Proposition 65 Warning 01.
Charging the 12-volt Lithium-ion battery
The 12-volt lithium-ion battery can be
charged using a GM approved charger
designed for lithium-Ion batteries. Follow the
instructions that come with the GM
approved charger.
{Warning
Use only GM approved jump start boxes
and charging tools. Use of unapproved
jump start boxes, charging tools, a loose
battery, or battery charger may cause
personal injury, death, or damage to the (Continued)
Warning (Continued)
vehicle. For GM approved jump start
boxes or charging tools, see
https://gmdesolutions.com.
Use the Battery Voltage info tile to
determine if your battery is low and needs
to be charged. See Instrument Cluster081
under the “Info Tiles” section for more
information.
GM recommends charging your 12-volt
lithium-ion battery when storing your
vehicle for long periods of time. See “Vehicle
Storage” later on in this section.
If the vehicle isn’t starting and the 12-volt
lithium-ion battery has run down, charging
the 12-volt lithium-ion battery may solve the
issue. See Jump Starting - North America
0 299.
High Voltage Battery (E-Ray)
Only a trained service technician should
inspect, test, or replace the high voltage
battery. The dealer has information on
how to recycle the high voltage battery.
There is also information available at
https://www.recyclemybattery.com.
{Warning
Damage to the high voltage battery or
high voltage system can create a risk of
electric shock, overheating, or fire.
If the vehicle is damaged from a
moderate to severe crash, flood, fire,
or other event, the vehicle should be
inspected as soon as possible. Until the
vehicle has been inspected, store it
outside at least 15 m (50 ft) from any
structure or anything that can burn.
Ventilate the vehicle by opening a
window or a door.
Contact Customer Assistance as soon as
possible to determine whether an
inspection is needed. See Customer
Assistance Offices 0331.
If the vehicle is in a crash, the sensing
system may shut down the high voltage
system. When this occurs, the high voltage
battery is disconnected and the vehicle will
not start. The SERVICE VEHICLE SOON
message in the Driver Information Center
(DIC) will display. Before the vehicle can

Tires
Every new GM vehicle has high-quality
tires made by a leading tire
manufacturer. See the warranty manual
for information regarding the tire
warranty and where to get service. For
additional information refer to the tire
manufacturer.
{Warning
.Poorly maintained and improperly
used tires are dangerous.
.Overloading the tires can cause
overheating as a result of too
much flexing. There could be a
blowout and a serious crash. See
Vehicle Load Limits 0174.
.Underinflated tires pose the same
danger as overloaded tires. The
resulting crash could cause serious
injury. Check all tires frequently to
(Continued)
Warning (Continued)
maintain the recommended
pressure. Tire pressure should be
checked when the tires are cold.
.Overinflated tires are more likely
to be cut, punctured, or broken by
a sudden impact —such as when
hitting a pothole. Keep tires at the
recommended pressure.
.Worn or old tires can cause a
crash. If the tread is badly worn,
replace them.
.Replace any tires that have been
damaged by impacts with
potholes, curbs, etc.
.Improperly repaired tires can cause
a crash. Only your dealer or an
authorized tire service center
should repair, replace, dismount,
and mount the tires.

UTQGS (Uniform Tire Quality Grading
Standards)
:A tire information system
that provides consumers with ratings
for a tire's traction, temperature, and
treadwear. Ratings are determined by
tire manufacturers using government
testing procedures. The ratings are
molded into the sidewall of the tire.
See Uniform Tire Quality Grading 0295.
Vehicle Capacity Weight
:The number
of designated seating positions
multiplied by 68 kg (150 lbs) plus the
rated cargo load. See Vehicle Load
Limits 0174.
Vehicle Maximum Load on the Tire
:
Load on an individual tire due to curb
weight, accessory weight, occupant
weight, and cargo weight.
Vehicle Placard
:A label permanently
attached to a vehicle showing the
vehicle's capacity weight and the
original equipment tire size and
recommended inflation pressure. See
“Tire and Loading Information Label”
under Vehicle Load Limits 0174.
Tire Pressure
Tires need the correct amount of air
pressure to operate effectively.
{Warning
Neither tire underinflation nor
overinflation is good. Underinflated
tires, or tires that do not have
enough air, can result in:
.Tire overloading and overheating,
which could lead to a blowout
.Premature or irregular wear
.Poor handling
.Reduced fuel economy for
internal combustion engine
vehicles
.Reduced range for electric vehicles
(Continued)
Warning (Continued)
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 0174.
How the vehicle is loaded affects
vehicle handling and ride comfort.
Never load the vehicle with more
weight than it was designed to carry.
