1. High Voltage BatteryCoolant Reservoir
2. Power Electronics Coolant Reservoir
Check to see if coolant is visible in
the power electronics coolant
reservoir (2). If coolant is visible but
the coolant level is below the cold
fill line on the side of the reservoir,
there could be a leak in the cooling
system.
The power electronics cooling
system supports the operation of
sensitive electronics. The power electronics cooling
system should only be serviced by a
qualified technician.
Engine Overheating
The vehicle has an indicator to warn
of engine overheating.
If the decision is made not to lift the
hood when this warning appears,
get service help right away. See
Roadside Assistance Program
0
345.
If the decision is made to lift the
hood, make sure the vehicle is
parked on a level surface.
Then check to see if the engine
cooling fans are running. If the
engine is overheating, the fans
should be running. If they are not,
do not continue to run the vehicle,
and have the vehicle serviced.
Caution
Do not run the engine when there
is a leak in the hybrid cooling
system. This can cause a loss of
all coolant and can damage the
system and the vehicle. Have any
leaks fixed right away.
Washer Fluid
What to Use
When adding windshield washer
fluid to the vehicle, be sure to read
the manufacturer's instructions
before use. If operating the vehicle
in an area where the temperature
may fall below freezing, use a fluid
that has sufficient protection against
freezing.

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 0167.

Tire Pressure
Tires need the correct amount of
air pressure to operate
effectively.Caution
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.
Overinflated tires, or tires that
have too much air, can
result in:
.Unusual wear.
(Continued)
Caution (Continued)
.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 0167.
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 0305.
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
