possible, and inflate the tires to the
pressure value shown on the Tire
and Loading Information Label.
See Tire Pressure on page 10‑44
for more information.
When the Light Flashes First and
Then is On Steady
This indicates that there may be a
problem with the Tire Pressure
Monitor System. The light flashes
for about a minute and stays on
steady for the remainder of the
ignition cycle. This sequence
repeats with every ignition cycle.
See Tire Pressure Monitor
Operation on page 10‑47 for
more information.Engine Oil Pressure Light
{WARNING
Do not keep driving if the oil
pressure is low. The engine can
become so hot that it catches fire.
Someone could be burned. Check
the oil as soon as possible and
have the vehicle serviced.
Notice: Lack of proper engine oil
maintenance can damage the
engine. The repairs would not be
covered by the vehicle warranty.

Driving and Operating 9-17
Do not turn the engine off when the
vehicle is moving. This will cause a
loss of power assist in the brake
and steering systems and disable
the airbags.
In an emergency:
1. Brake using a firm and steadypressure. Do not pump the
brakes repeatedly. This may
deplete power assist, requiring
increased brake pedal force.
2. Shift the vehicle to neutral. This can be done while the vehicle is
moving. After shifting to neutral,
firmly apply the brakes and steer
the vehicle to a safe location. 3. Come to a complete stop, shift
to P (Park), and turn the ignition
to LOCK/OFF. On vehicles with
an automatic transmission, the
shift lever must be in P (Park) to
turn the ignition switch to the
LOCK/OFF position.
4. Set the parking brake. See Parking Brake on page 9‑29
The steering can bind with the
wheels turned off center. If this
happens, move the steering wheel
from left to right while turning the
key to ACC/ACCESSORY. If this
doesn't work, then the vehicle
needs service.
B (ACC/ACCESSORY): This is the
position in which you can operate
the radio and windshield wipers
while the engine is off. To use
ACC/ACCESSORY, turn the key
clockwise. C (ON/RUN):
This position can
be used to operate the electrical
accessories and to display some
instrument panel cluster warning
and indicator lights. The switch
stays in this position when the
engine is running.
If you leave the key in the ACC/
ACCESSORY or ON/RUN position
with the engine off, the battery could
be drained. You may not be able to
start the vehicle if the battery is
allowed to drain for an extended
period of time.
D (START): This is the position that
starts the engine. When the engine
starts, release the key. The ignition
switch returns to ON/RUN for
driving.
A warning chime will sound and the
Driver Information Center (DIC) will
display DRIVER DOOR OPEN
when the driver door is opened, the
ignition is in ACC/ACCESSORY or
LOCK/OFF, and the key is in the
ignition. See Door Ajar Messages
on page 5‑29 for more information.

For customers who do not use TOP
TIER Detergent Gasoline regularly,
one bottle of GM Fuel System
Treatment PLUS, added to the fuel
tank at every engine oil change,
can help clean deposits from fuel
injectors and intake valves. GM Fuel
System Treatment PLUS is the only
gasoline additive recommended by
General Motors. It is available at
your dealer.
Gasolines containing oxygenates,
such as ethers and ethanol, and
reformulated gasolines might be
available in your area. We
recommend that you use these
gasolines, if they comply with the
specifications described earlier.
However, E85 (85% ethanol) and
other fuels containing more than
10% ethanol must not be used in
vehicles that were not designed
for those fuels.Notice:
This vehicle was not
designed for fuel that contains
methanol. Do not use fuel
containing methanol. It can
corrode metal parts in the fuel
system and also damage plastic
and rubber parts. That damage
would not be covered under the
vehicle warranty.
Some gasolines that are not
reformulated for low emissions can
contain an octane-enhancing
additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT); ask the attendant
where you buy gasoline whether the
fuel contains MMT. We recommend
against the use of such gasolines.
Fuels containing MMT can reduce
the life of spark plugs and the
performance of the emission control
system could be affected. The
malfunction indicator lamp might
turn on. If this occurs, return to your
dealer for service.Fuel E85 (85% Ethanol)
Vehicles that have a FlexFuel badge
and a yellow fuel cap can use either
unleaded gasoline or ethanol fuel
containing up to 85% ethanol (E85).
For all other vehicles, use only the
unleaded gasoline described under
Recommended Fuel on page 9‑35.
We encourage the use of E85 in
vehicles that are designed to use it.
The ethanol in E85 is a “renewable”
fuel, meaning it is made from
renewable sources such as corn
and other crops.
Many service stations will not have
an 85% ethanol fuel (E85) pump
available. The U.S. Department of
Energy has an alternative fuels
website (www.eere.energy.gov/afdc/
infrastructure/locator.html) that can
help you find E85 fuel. Those
stations that do have E85 should
have a label indicating ethanol
content. Do not use the fuel if the
ethanol content is greater than 85%.

5. Install the coolant recovery tankcap and the pressure cap. After
a day or two of driving, when the
engine is cold, check the coolant
level in the recovery tank. If it is
low, refill it to the COLD
FILL line.
If the coolant in the recovery tank is
constantly low, have a dealer
service department inspect the
vehicle for leaks.
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 a coolant temperature
gauge and a warning light on the
instrument panel that indicate an
overheated engine condition. See
Engine Coolant Temperature Gauge
on page 5‑13 andEngine Coolant
Temperature Warning Light on
page 5‑22.
In addition, there is an ENGINE
OVERHEATED IDLE ENGINE and
an ENGINE OVERHEATED STOP
ENGINE message displayed on the
vehicle Driver Information Center
(DIC). See Engine Cooling System
Messages on page 5‑30 for more
information.
If it is decided not to lift the hood
when this warning appears, but
instead get service help right away,
see Roadside Assistance Program
on page 13‑7. If it is decided 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, both fans
should be running. If they are not,
do not continue to run the engine
and have the vehicle serviced.
Notice:
Engine damage from
running the engine without
coolant is not covered by
the warranty.
Notice: If the engine catches fire
while driving with no coolant, the
vehicle can be badly damaged.
The costly repairs would not be
covered by the vehicle warranty.
See Overheated Engine
Protection Operating Mode on
page 10‑21 for information on
driving to a safe place in an
emergency.

Vehicle Care 10-23
Brakes
This vehicle has disc brakes.
Disc brake pads have built-in wear
indicators that make a high-pitched
warning sound when the brake pads
are worn and new pads are needed.
The sound can come and go or be
heard all the time the vehicle is
moving, except when applying the
brake pedal firmly.
{WARNING
The brake wear warning sound
means that soon the brakes will
not work well. That could lead to
a crash. When the brake wear
warning sound is heard, have the
vehicle serviced.
Notice: Continuing to drive with
worn-out brake pads could result
in costly brake repair. Some driving conditions or climates
can cause a brake squeal when the
brakes are first applied or lightly
applied. This does not mean
something is wrong with the brakes.
Properly torqued wheel nuts are
necessary to help prevent brake
pulsation. When tires are rotated,
inspect brake pads for wear and
evenly tighten wheel nuts in the
proper sequence to torque
specifications in
Capacities and
Specifications on page 12‑2.
Brake linings should always be
replaced as complete axle sets.
Brake Pedal Travel
See your dealer if the brake pedal
does not return to normal height,
or if there is a rapid increase in
pedal travel. This could be a sign
that brake service might be
required.
Brake Adjustment
Every time the brakes are applied,
with or without the vehicle moving,
the brakes adjust for wear.
Replacing Brake System Parts
The braking system on a vehicle is
complex. Its many parts have to be
of top quality and work well together
if the vehicle is to have really good
braking. The vehicle was designed
and tested with top-quality brake
parts. When parts of the braking
system are replaced, be sure to get
new, approved replacement parts.
If this is not done, the brakes might
not work properly. For example,
installing disc brake pads that are
wrong for the vehicle, can change
the balance between the front and
rear brakes —for the worse. The
braking performance expected can
change in many other ways if the
wrong replacement brake parts are
installed.
