236 Vehicle Care
If ambient temperatures are
anticipated below−28 °C (−18 °F),
make sure a proper mixture ratio of
50% DEX-COOL coolant and 50%
clean, drinkable water is used.
Checking Coolant
The vehicle must be on a level
surface when checking the coolant
level.
Check to see if coolant is visible in
the coolant surge tank. If the coolant
inside the coolant surge tank is
boiling, do not do anything else until
it cools down. If coolant is visible
but the coolant level is not at or
above the cold fill line, add a
mixture of 40% DEX-COOL coolant
and 60% clean, drinkable water at
the coolant recovery tank, but be
sure the cooling system is cool
before this is done. See Engine
Overheating 0237.
The engine coolant surge tank is
toward the rear of the engine
compartment on the passenger side
of the vehicle. See Engine
Compartment Overview 0218.
When the engine is cold, the coolant
level should be at the cold fill line on
the coolant surge tank.
When the engine is hot, the level
could be higher than the cold fill
line. If the coolant is below the cold
fill line when the engine is hot, there
could be a leak in the cooling
system.
If the coolant is low, add the coolant
or take the vehicle to your dealer for
service.
How to Add Coolant to the
Coolant Surge Tank
{Warning
You can be burned if you spill
coolant on hot engine parts.
Coolant contains ethylene glycol
and it will burn if the engine parts
are hot enough. Do not spill
coolant on a hot engine.
{Warning
Steam and scalding liquids from a
hot cooling system can blow out
and burn you badly. Never turn
the cap when the cooling system,
including the surge tank pressure
cap, is hot. Wait for the cooling
system and surge tank pressure
cap to cool.
If coolant is needed, add the proper
DEX-COOL coolant mixture directly
to the surge tank, but be sure the
cooling system is cool before this
is done. 1. When the cooling system, including the coolant surge
tank pressure cap and upper
radiator hose, is no longer hot,
remove the pressure cap.
Turn the pressure cap slowly
counterclockwise about
one-quarter turn and then stop.
If a hiss is heard, wait for that
to stop. A hiss means there is
still some pressure left.

2. Keep turning the pressure capslowly, and remove it.
3. Fill the coolant surge tank with the proper DEX-COOL coolant
mixture until the level inside
stabilizes at the cold fill line on
the front of the surge tank.
4. With the coolant surge tank pressure cap off, start the
engine and let it run until the
upper radiator hose can be felt
getting hot. Any time during
this procedure, watch out for
the engine cooling fan.
By this time, the coolant level
inside the coolant surge tank
may be lower. If the level is
lower, add more of the proper
mixture to the coolant surge
tank until the level stabilizes at
the cold fill line on the coolant
surge tank.
5. Replace the pressure cap tightly.
Check the level in the surge
tank when the system has
cooled down. If the coolant is
not at the proper level, repeat Steps 1−4, then reinstall the
pressure cap. If the coolant is
not at the proper level when
the system cools down again,
see your dealer.
Caution
If the pressure cap is not tightly
installed, coolant loss and
possible engine damage may
occur. Be sure the cap is properly
and tightly secured.
Engine Overheating
The vehicle has several indicators
to warn of engine overheating.
There is an engine coolant
temperature gauge on the
instrument cluster. See
Engine
Coolant Temperature Gauge 0103.
The vehicle may also display a
message on the Driver Information
Center (DIC). See Engine Cooling
System Messages 0123. If the decision is made not to lift the
hood but to get service help right
away, see
Roadside Assistance
Program 0319.
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 fan is running. If the engine
is overheating, the fan should be
running. If it is not, do not continue
to run the engine and have the
vehicle serviced.
Caution
Running the engine without
coolant may cause damage or a
fire. Vehicle damage would not be
covered by the vehicle warranty.

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 0171.
(Continued)
Warning (Continued)
.Underinflated tires pose
the same danger as
overloaded tires. The
resulting crash could
cause serious injury.
Check all tires frequently
to 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.

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.
.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.
On rare occasions, vehicles with
P245/40ZR18 and P285/35ZR19
size tires may experience a
rough ride at the tire pressure
recommended on the Tire and
Loading Information label. To
improve ride performance,
decrease the tire pressure to no
less than 205 kPa (30 psi) when
the tire is cold. This may reduce
fuel economy and cause the low
tire pressure warning to occur
more often.
Inflate the tires to the
recommended pressure once
rough ride road conditions have
passed. For additional information
regarding how much weight the
vehicle can carry, and an
example of the Tire and Loading
Information label, see
Vehicle
Load Limits 0171. 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.
How to Check
Use a good quality pocket-type
gauge to check the 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).
