8-38 Driving and Operating
Fuel Economy Mode
The vehicle may have a Fuel
Economy Mode. When engaged,
fuel economy mode can improve the
vehicle's fuel economy.
Press the“eco”(economy) button by
the shift lever to turn this feature on
or off. The “eco”light in the
instrument cluster will come on
when engaged. See Fuel Economy
Light
on page 4‑23. For vehicles with a Driver Information Center
(DIC) an
“ECO Mode On” message
displays. See Fuel System
Messages
on page 4‑32for more
information.
When Fuel Economy Mode is on:
.The transmission will upshift
sooner and downshift later.
.The torque converter clutch will
apply sooner and stay on longer.
.The gas pedal will be less
sensitive.
.The vehicle's computer will more
aggressively shut off fuel to the
engine under deceleration.
.The engine idle speed will be
lower.
.Driving performance is more
conservative.
Drive Systems
All-Wheel Drive
With this feature, engine power is
always sent to all four wheels. It is
fully automatic, and adjusts itself as
needed for road conditions.
When using a compact spare tire on
an AWD vehicle, the system
automatically detects the compact
spare and disables AWD. To restore
AWD operation and prevent
excessive wear on system, replace
the compact spare with a full-size
tire as soon as possible. See
Compact Spare Tire
on page 9‑76for more information.

Vehicle Care 9-57
TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identification code. Any time you
rotate your vehicle's tires or replace
one or more of the TPMS sensors,
the identification codes will need to
be matched to the new tire/wheel
position. The sensors are matched
to the tire/wheel positions in the
following order: driver side front tire,
passenger side front tire, passenger
side rear tire, and driver side rear
tire using a TPMS diagnostic tool.
See your dealer/retailer for service.
The TPMS sensors can also be
matched to each tire/wheel position
by increasing or decreasing the
tire's air pressure. If increasing the
tire's air pressure, do not exceed
the maximum inflation pressure
indicated on the tire's sidewall.To decrease air-pressure out of a
tire you can use the pointed end of
the valve cap, a pencil-style air
pressure gauge, or a key.
You have two minutes to match
the first tire/wheel position, and
five minutes overall to match all four
tire/wheel positions. If it takes longer
than two minutes, to match the first
tire and wheel, or more than
five minutes to match all four tire
and wheel positions the matching
process stops and you need to
start over.
The TPMS sensor matching process
is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to
ON/RUN with the engine off. 3. Press the Remote Keyless Entry
(RKE) transmitter's lock and
unlock buttons at the same time
for approximately five seconds.
The horn sounds twice to signal
the receiver is in relearn mode
and Tire Learning Active
message displays on the DIC
screen.
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 five seconds, or until a
horn chirp sounds. The horn
chirp, which may take up to
30 seconds to sound, confirms
that the sensor identification
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.

Customer Information 12-11
Insuring Your Vehicle
Protect your investment in your GM
vehicle with comprehensive and
collision insurance coverage. There
are significant differences in the
quality of coverage afforded by
various insurance policy terms.
Many insurance policies provide
reduced protection to your GM
vehicle by limiting compensation for
damage repairs by using
aftermarket collision parts. Some
insurance companies will not
specify aftermarket collision parts.
When purchasing insurance, we
recommend that you assure your
vehicle will be repaired with GM
original equipment collision parts.
If such insurance coverage is not
available from your current
insurance carrier, consider switching
to another insurance carrier.If your vehicle is leased, the leasing
company may require you to have
insurance that assures repairs with
Genuine GM Original Equipment
Manufacturer (OEM) parts or
Genuine Manufacturer replacement
parts. Read your lease carefully, as
you may be charged at the end of
your lease for poor quality repairs.
If a Crash Occurs
If there has been an injury, call
emergency services for help. Do not
leave the scene of a crash until all
matters have been taken care of.
Move the vehicle only if its position
puts you in danger, or you are
instructed to move it by a police
officer.
Give only the necessary information
to police and other parties involved
in the crash.
For emergency towing see
Roadside Assistance Program
on
page 12‑6. Gather the following information:
.Driver's name, address, phone
number
.Driver's license number
.Owner's name, address, phone
number
.Vehicle license plate
.Vehicle make, model and
model year
.Vehicle Identification
Number (VIN)
.Insurance company and policy
number
.General description of the
damage to the other vehicle
Choose a reputable repair facility
that uses quality replacement parts.

section.

Will You See After an Airbag
Inflates? on page 2‑32.
