1-18 In Brief
Engine Oil Life System
The engine oil life system calculates
engine oil life based on vehicle use
and displays a DIC message when
it is necessary to change the engine
oil and filter.
Resetting the Oil Life System
1. Turn the ignition to ON/RUN,with the engine off.
2. Press and release the stem in the lower center of the
instrument cluster until the
“Oil Life” message is displayed.
3. Once the alternating “Oil Life”
and “Reset” messages appear,
press and hold the stem
until several beeps sound.
This confirms that the oil life
system has been reset.
4. Turn the key to LOCK/OFF.
See Engine Oil Life System
on
page 10‑11.
Fuel E85 (85% Ethanol)
Vehicles that have the
5.3L V8 engine (Code P) have
a yellow fuel cap and can use either
unleaded gasoline or ethanol fuel
containing up to 85% ethanol (E85).
See Fuel E85 (85% Ethanol)
on
page 9‑66. In all other engines,
use only the unleaded gasoline
described under Recommended
Fuel on page 9‑64.
Driving for Better Fuel
Economy
Driving habits can affect fuel
mileage. Here are some driving
tips to get the best fuel economy
possible.
.Avoid fast starts and accelerate
smoothly.
.Brake gradually and avoid
abrupt stops.
.Avoid idling the engine for long
periods of time.
.When road and weather
conditions are appropriate, use
cruise control, if equipped.
.Always follow posted speed
limits or drive more slowly when
conditions require.
.Keep vehicle tires properly
inflated.
.Combine several trips into a
single trip.
.Replace the vehicle's tires with
the same TPC Spec number
molded into the tire's sidewall
near the size.
.Follow recommended scheduled
maintenance.

2-10 Keys, Doors and Windows
To avoid setting off the alarm by
accident:
.Lock the vehicle with the manual
door lock lever, the power door
lock switch, or the key, after the
doors are closed.
.Unlock the doors by pressing
the unlock button on the RKE
transmitter or by contacting
OnStar. Unlocking a door any
other way activates the alarm.
Press unlock on the RKE
transmitter, start the vehicle with
the correct key, or have OnStar
unlock the doors to turn the alarm
off. The alarm does not stop if a
door is unlocked any other way.
Testing the Alarm
To test the alarm:
1. From inside the vehicle, lock the doors with the RKE transmitter.
2. Unlock the door with the manual door lock and open the door.
The pre-alarm should sound
followed by the full alarm about
10 seconds later.
3. Press the unlock button on the RKE transmitter or start the
engine to turn the alarm off.
If the alarm does not sound but the
lights flash, check to see if the horn
works. The horn fuse could be
blown. To replace the fuse, see
Fuses and Circuit Breakers
on
page 10‑39.
If the alarm does not sound or the
front turn signal lamps do not flash,
see your dealer for service.
Immobilizer
See Radio Frequency Statementon
page 13‑16for information
regarding Part 15 of the Federal
Communications Commission (FCC)
Rules and RSS-210/211 of Industry
Canada.
Immobilizer
Operation (U.S.)
Passlock®is a passive
theft-deterrent system that enables
fuel if the vehicle is started with a
valid key. If an incorrect key is used
or the ignition lock cylinder is
tampered with, the fuel system is
disabled and the vehicle does not
start.
The security light turns off
approximately five seconds after
the engine is started. See Security
Light on page 5‑17.

Seats and Restraints 3-33
Rollover capable roof-rail airbags
are designed to help contain the
head and chest of occupants in the
outboard seating positions in the
first and second rows. The rollover
capable roof-rail airbags are
designed to help reduce the risk of
full or partial ejection in rollover
events, although no system can
prevent all such ejections.
But airbags would not help in
many types of collisions, primarily
because the occupant's motion is
not toward those airbags. SeeWhen
Should an Airbag Inflate?
on
page 3‑31for more information.
Airbags should never be regarded
as anything more than a supplement
to safety belts.
What Will You See After
an Airbag Inflates?
After the frontal airbags inflate, they
quickly deflate, so quickly that some
people may not even realize an
airbag inflated. Roof-rail airbags
may still be at least partially inflated
for some time after they deploy.
Some components of the airbag
module may be hot for several
minutes. For location of the airbag
modules, see What Makes an
Airbag Inflate? on page 3‑32.
The parts of the airbag that come
into contact with you may be warm,
but not too hot to touch. There may
be some smoke and dust coming
from the vents in the deflated
airbags. Airbag inflation does not
prevent the driver from seeing out
of the windshield or being able to
steer the vehicle, nor does it prevent
people from leaving the vehicle.
{WARNING
When an airbag inflates, there
may be dust in the air. This dust
could cause breathing problems
for people with a history of
asthma or other breathing trouble.
To avoid this, everyone in the
vehicle should get out as soon
as it is safe to do so. If you have
breathing problems but cannot
get out of the vehicle after an
airbag inflates, then get fresh air
by opening a window or a door.
If you experience breathing
problems following an airbag
deployment, you should seek
medical attention.
The vehicle has a feature that may
automatically unlock the doors, turn
on the interior lamps and hazard
warning flashers, and shut off the
fuel system after the airbags inflate.

3-34 Seats and Restraints
You can lock the doors, turn off the
interior lamps and hazard warning
flashers by using the controls for
those features.
{WARNING
A crash severe enough to
inflate the airbags may have
also damaged important functions
in the vehicle, such as the fuel
system, brake and steering
systems, etc. Even if the vehicle
appears to be drivable after a
moderate crash, there may be
concealed damage that could
make it difficult to safely operate
the vehicle.
Use caution if you should attempt
to restart the engine after a crash
has occurred.If damage to the vehicle is minor,
you may attempt to restart the
vehicle's engine. Note: If the fuel
system has been shut off after an
airbag has inflated, you may not
be able to restart the engine for up
to ten minutes. See
Starting the
Engineon page 9‑35for more
information.
In many crashes severe enough to
inflate the airbag, windshields are
broken by vehicle deformation.
Additional windshield breakage
may also occur from the right front
passenger airbag.
.Airbags are designed to inflate
only once. After an airbag
inflates, you will need some
new parts for the airbag system.
If you do not get them, the
airbag system will not be there to help protect you in another
crash. A new system will include
airbag modules and possibly
other parts. The service manual
for your vehicle covers the need
to replace other parts.
.The vehicle has a crash sensing
and diagnostic module which
records information after a
crash. See
Vehicle Data
Recording and Privacy
on
page 13‑15and Event Data
Recorders on page 13‑15.
.Let only qualified technicians
work on the airbag systems.
Improper service can mean that
an airbag system will not work
properly. See your dealer for
service.
