How to Add Coolant to the
Radiator
{CAUTION
An electric engine cooling fan
under the hood can start up even
when the engine is not running
and can cause injury. Keep
hands, clothing, and tools away
from any underhood electric fan.
{CAUTION
Steam and scalding liquids from a
hot cooling system can blow out
and burn you badly. They are
under pressure, and if you turn the
surge tank pressure cap — even a
little — they can come out at high
speed. Never turn the cap when
the cooling system, including the
surge tank pressure cap, is hot.
(Continued)
CAUTION (Continued)
Wait for the cooling system and
surge tank pressure cap to cool
if you ever have to turn the
pressure cap.
If coolant is needed, add the proper
mixture directly to the radiator,
but be sure the cooling system is
cool before this is done.
1. Detach fasteners and lift off
the panel that covers the
radiator cap.2. Remove the radiator pressure
cap when the cooling system,
including the upper radiator hose,
is no longer hot.
Turn the pressure cap slowly
counterclockwise about one full
turn. If you hear a hiss, wait
for that to stop. A hiss means
there is still some pressure left
in the system.
3. Keep turning the pressure cap
slowly and remove it.
4. Fill the radiator to the base of
the ller neck with the proper
DEX-COOL coolant mixture.
5. When coolant begins to ow out
of the ller neck, reinstall the
pressure cap. Be sure to secure
it tightly.

4. Start with the driver side front tire.
5. Remove the valve cap from the
valve cap stem. Activate the
TPMS sensor by increasing or
decreasing the tire’s air pressure
for ve seconds, or until a horn
chirp sounds. The horn chirp,
which may take up to 30 seconds
to sound, con rms that the sensor
identi cation code has been
matched to this tire and wheel
position.6. Proceed to the passenger side
front tire, and repeat the
procedure in Step 5.
7. Proceed to the passenger side
rear tire, and repeat the
procedure in Step 5.
8. Proceed to the driver side rear
tire, and repeat the procedure
in Step 5. The horn sounds
two times to indicate the sensor
identi cation code has been
matched to the driver side rear
tire, and the TPMS sensor
matching process is no longer
active. The TIRE LEARNING
ACTIVE message on the
DIC display screen goes off.
9. Turn the ignition switch to
LOCK/OFF.
10. Set all four tires to the
recommended air pressure level
as indicated on the Tire and
Loading Information label.
11. Put the valve caps back on the
valve stems.Tire Inspection and
Rotation
We recommend that you
regularly inspect the vehicle’s
tires, including the spare tire, if
the vehicle has one, for signs of
wear or damage. SeeWhen It Is
Time for New Tires on page 5-50
for more information.
Tires should be rotated
every 5,000 to 8,000 miles
(8 000 to 13 000 km). See
Scheduled Maintenance on
page 6-3.
The purpose of a regular tire
rotation is to achieve a uniform
wear for all tires on the vehicle.
This will ensure that the vehicle
continues to perform most like it
did when the tires were new.
5-48 Service and Appearance Care

Non-TPC Spec rated tires may
give a low-pressure warning that
is higher or lower than the proper
warning level you would get with
TPC Spec rated tires. SeeTire
Pressure Monitor System on
page 5-43.
Your vehicle’s original equipment
tires are listed on the Tire and
Loading Information Label.
SeeLoading the Vehicle on
page 4-16, for more information
about the Tire and Loading
Information Label and its location
on your vehicle.
Different Size Tires and
Wheels
If you add wheels or tires that are a
different size than your original
equipment wheels and tires, this
could affect the way your vehicle
performs, including its braking, ride
and handling characteristics,
stability, and resistance to rollover.Additionally, if your vehicle has
electronic systems such as anti-lock
brakes, rollover airbags, traction
control, and electronic stability
control, the performance of these
systems can be affected.
{CAUTION
If you add different sized wheels,
your vehicle may not provide an
acceptable level of performance
and safety if tires not
recommended for those wheels
are selected. You may increase
the chance that you will crash and
suffer serious injury. Only use GM
speci c wheel and tire systems
developed for your vehicle, and
have them properly installed by a
GM certi ed technician.
SeeBuying New Tires on page 5-50
andAccessories and Modifications
on page 5-3for additional
information.
Uniform Tire Quality
Grading
Quality grades can be found
where applicable on the tire
sidewall between tread shoulder
and maximum section width.
For example:
Treadwear 200 Traction AA
Temperature A
The following information relates
to the system developed by the
United States National Highway
Traffic Safety Administration
(NHTSA), which grades tires
by treadwear, traction, and
temperature performance.
This applies only to vehicles
sold in the United States.

2. Unwrap the sealant/air hose (F)
and the power plug (H).
3. Place the kit on the ground.
Make sure the tire valve
stem is positioned close to the
ground so the hose will reach it.
4. Remove the valve stem cap from
the at tire by turning it
counterclockwise.
5. Attach the sealant/air hose (F)
onto the tire valve stem. Turn
it clockwise until it is tight.
6. Plug the power plug (H) into the
accessory power outlet in the
vehicle. Unplug all items from
other accessory power outlets.
SeeAccessory Power Outlet(s)
on page 3-17.
If the vehicle has an accessory
power outlet, do not use the
cigarette lighter.
If the vehicle only has a cigarette
lighter, use the cigarette lighter.
Do not pinch the power plug
cord in the door or window.7. Start the vehicle. The vehicle
must be running while using
the air compressor.
8. Turn the selector switch (A)
counterclockwise to the
Sealant + Air position.
9. Press the on/off (B) button to
turn the tire sealant and
compressor kit on.
The compressor will inject
sealant and air into the tire.
The pressure gage (C) will initially
show a high pressure while the
compressor pushes the sealant
into the tire. Once the sealant is
completely dispersed into the tire,
the pressure will quickly drop and
start to rise again as the tire
in ates with air only.10. In ate the tire to the
recommended in ation
pressure using the pressure
gage (C). The recommended
in ation pressure can be
found on the Tire and Loading
Information label. See
Inflation - Tire Pressure on
page 5-42.
The pressure gage (C) may
read higher than the actual tire
pressure while the compressor
is on. Turn the compressor
off to get an accurate pressure
reading. The compressor
may be turned on/off until the
correct pressure is reached.
5-60 Service and Appearance Care

Notice:If the recommended
pressure cannot be reached after
approximately 25 minutes, the
vehicle should not be driven
farther. The tire is too severely
damaged and the tire sealant and
compressor kit cannot in ate the
tire. Remove the power plug from
the accessory power outlet and
unscrew the in ating hose from
the tire valve. SeeRoadside
Assistance Program on page 7-6.
11. Press the on/off button (B) to
turn the tire sealant and
compressor kit off.
The tire is not sealed and
will continue to leak air until
the vehicle is driven and the
sealant is distributed in the tire,
therefore, Steps 12 through 18
must be done immediately after
Step 11.
Be careful while handling the tire
sealant and compressor kit as it
could be warm after usage.12. Unplug the power plug (H) from
the accessory power outlet in
the vehicle.
13. Turn the sealant/air hose (F)
counterclockwise to remove it
from the tire valve stem.
14. Replace the tire valve stem cap.
15. Replace the sealant/air hose (F),
and the power plug (H) back in
their original location.
16. If the at tire was able to in ate
to the recommended in ation
pressure, remove the maximum
speed label from the sealant
canister (E) and place it in a
highly visible location. The
label is a reminder not to exceed
55 mph (90 km/h) until the
damaged tire is repaired or
replaced.17. Return the equipment to its
original storage location in
the vehicle.
18. Immediately drive the vehicle
5 miles (8 km) to distribute the
sealant in the tire.
19. Stop at a safe location and
check the tire pressure.
Refer to Steps 1 through 11
under “Using the Tire Sealant
and Compressor Kit without
Sealant to In ate a Tire
(Not Punctured).”
If the tire pressure has fallen
more than 10 psi (68 kPa) below
the recommended in ation
pressure, stop driving the
vehicle. The tire is too severely
damaged and the tire sealant
cannot seal the tire. See
Roadside Assistance Program
on page 7-6.
If the tire pressure has not
dropped more than 10 psi
(68 kPa) from the recommended
in ation pressure, in ate the
tire to the recommended
in ation pressure.
