4. With the coolant surge tankpressure 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 FULL COLD mark on the
coolant surge tank.
5. Replace the pressure cap. Be sure the pressure cap is
hand-tight and fully seated.
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
through 4, then reinstall the
pressure cap. If the coolant is
not at the proper level when the
system cools down again, see
the dealer.
Notice: 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 panel cluster.
See Engine Coolant Temperature
Gauge on page 5‑16. The vehicle
may also display a COOLANT
OVER TEMPERATURE
message on the Driver Information
Center (DIC). See Engine Cooling
System Messages on page 5‑39
for more information.
If the decision is made not to lift the
hood but to get service help right
away. See Roadside Assistance
Program (U.S. and Canada) on
page 13‑8 orRoadside Assistance
Program (Mexico) on page 13‑10.

Run-Flat Tires
This vehicle, when new, had run-flat
tires. There is no spare tire, no tire
changing equipment, and no place
to store a tire in the vehicle.
The vehicle also has a Tire
Pressure Monitor System (TPMS)
that indicates a loss of tire pressure
in any of the tires.
{WARNING
If the low tire warning light
displays on the instrument panel
cluster, the handling capabilities
will be reduced during severe
maneuvers. Driving too fast could
cause loss of control and you or
others could be injured. Do not
drive over 90 km/h (55 mph)
when the low tire warning light is
displayed. Drive cautiously and
check the tire pressures as soon
as possible.If a tire goes flat, there is no need to
stop on the side of the road to
change the tire. Continue driving,
however, do not drive too far or too
fast. Driving on the tire may not be
possible if there is permanent
damage. The tire can be driven with
no air pressure for up to 105 km
(65 miles) at speeds slower than
90 km/h (55 mph). The shorter the
distance and the slower the speed,
the greater the chance the tire will
not have to be replaced. As soon
as possible, contact the nearest
authorized GM or run-flat servicing
facility for inspection and repair or
replacement. When driving on a
deflated run-flat tire, avoid potholes
and other road hazards that could
damage the tire and/or wheel
beyond repair. When a tire has been
damaged, or if driven any distance
on a deflated run-flat tire, check with
an authorized run-flat tire service
center to determine whether the
tire can be repaired or should be
replaced. To maintain the run-flat
feature, all replacement tires must
be run-flat tires. To locate the nearest GM or run-flat
servicing facility, call Roadside
Assistance. See
Roadside
Assistance Program (U.S. and
Canada) on page 13‑8 orRoadside
Assistance Program (Mexico) on
page 13‑10 for details.
The valve stems on run-flat
tires have sensors that are part of
the TPMS. See Tire Pressure
Monitor System on page 10‑64.
These sensors contain batteries that
are designed to last for 10 years
under normal driving conditions.
See your dealer for wheel or sensor
replacement.
Notice: Using liquid sealants can
damage the tire valves and tire
pressure monitor sensors in the
run-flat tires. This damage is not
covered by the vehicle warranty.
Do not use liquid sealants in
run-flat tires.

Tire Pressure Monitor
Operation
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The TPMS is designed to warn the
driver when a low tire pressure
condition exists. TPMS sensors
are mounted onto each tire and
wheel assembly on your vehicle.
The TPMS sensors monitor the air
pressure in the tires and transmits
the tire pressure readings to a
receiver located in the vehicle.
When a low tire pressure condition
is detected, the TPMS illuminates
the low tire pressure warning light,
located in the instrument cluster.
If the warning light comes on,
stop as soon as possible and inflate
the tires to the recommendedpressure shown on the tire loading
information label. See
Vehicle Load
Limits on page 9‑14.
A message to check the pressure in
a specific tire displays in the Driver
Information Center (DIC). The low
tire pressure warning light and the
DIC warning message appear at
each ignition cycle until the tires
are inflated to the correct inflation
pressure. Using the DIC, tire
pressure levels can be viewed.
For additional information and
details about the DIC operation and
displays see Driver Information
Center (DIC) on page 5‑26 and
Tire Messages on page 5‑49.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven.
This could be an early indicator that
the air pressure is getting low and
needs to be inflated to the proper
pressure. A Tire and Loading Information label
shows the size of the original
equipment tires and the correct
inflation pressure for the tires when
they are cold. See
Vehicle Load
Limits on page 9‑14, for an example
of the Tire and Loading Information
label and its location. Also see
Tire Pressure on page 10‑62 for
additional information.
The TPMS can warn about a
low tire pressure condition but it
does not replace normal tire
maintenance. See Tire Inspection
on page 10‑68, Tire Rotation on
page 10‑68, When It Is Time for
New Tires on page 10‑69, and
Tires on page 10‑54.
Notice: Tire sealant materials are
not all the same. A non-approved
tire sealant could damage the
TPMS sensors. TPMS sensor
damage caused by using an
incorrect tire sealant is not
covered by the vehicle
warranty. Always use only the

Underbody Maintenance
Use plain water to flush dirt and
debris from the vehicle's underbody.
Your dealer or an underbody car
washing system can do this. If not
removed, rust and corrosion can
develop.
Fiberglass Springs
(Composite Springs)
Notice:Do not use acidic or
corrosive cleaning products,
engine degreasers, or aluminum
cleaning agents on fiberglass
springs as it may cause damage.
The repairs would not be
covered by the vehicle's warranty.
Use only approved cleaners.
Sheet Metal Damage
If the vehicle is damaged and
requires sheet metal repair or
replacement, make sure the body
repair shop applies anti-corrosion material to parts repaired or
replaced to restore corrosion
protection.
Original manufacturer replacement
parts will provide the corrosion
protection while maintaining the
vehicle warranty.
Finish Damage
Quickly repair minor chips and
scratches with touch-up materials
available from your dealer to avoid
corrosion. Larger areas of finish
damage can be corrected in your
dealer's body and paint shop.
Chemical Paint Spotting
Airborne pollutants can fall upon
and attack painted vehicle surfaces
causing blotchy, ring-shaped
discolorations, and small, irregular
dark spots etched into the paint
surface.
Interior Care
To prevent dirt particle abrasions,
regularly clean the vehicle's interior.
Immediately remove any soils.
Note that newspapers or dark
garments that can transfer color
to home furnishings can also
permanently transfer color to the
vehicle's interior.
Use a soft bristle brush to remove
dust from knobs and crevices on the
instrument cluster. Using a mild
soap solution, immediately remove
hand lotions, sunscreen, and insect
repellant from all interior surfaces or
permanent damage may result.
Your dealer may have products for
cleaning the interior. Use cleaners
specifically designed for the
surfaces being cleaned to prevent
permanent damage. To prevent
overspray, apply all cleaners
directly to the cleaning cloth.
