Battery Replacement
Under normal use, the battery in your keyless access
transmitter should last about three years.
You can tell the battery is weak if the transmitter will not
work at the normal range in any location. If you have
to get close to your vehicle before the transmitter works,
it is probably time to change the battery.
A weak battery may also cause the DIC to display NO
FOBS DETECTED when you try to start the vehicle.
If this happens, place the transmitter in the glove
box transmitter pocket with the buttons facing towards
the passenger’s side. Then, with the vehicle in PARK (P)
for an automatic transmission press the break pedal
and the START button, or if your vehicle has a manual
transmission, press the clutch and the START button.
Although this will start the vehicle, it is recommended
that you replace the transmitter battery as soon as
possible. The DIC may display FOB BATTERY LOW.
Notice:When replacing the battery, use care not to
touch any of the circuitry. Static from your body
transferred to these surfaces may damage the
transmitter.1. Insert a coin or similar object into the slot on the
back of the transmitter and gently pry apart the
front and back.
2. Gently pull the battery out of the transmitter.
3. Put the new battery in the transmitter, positive (+)
side down. Use a battery, type CR2032, or
equivalent.
4. Reassemble the transmitter. Make sure to put it
together so water will not get in.
5. Test the transmitter.

Retained Accessory Power (RAP)
With RAP, your power windows and the audio system
will continue to work for up to 10 minutes after the
engine is turned off or until either door is opened. If a
door is opened, the power windows and audio system
will shut off.
Starting the Engine
Move your shift lever to PARK (P) or NEUTRAL (N) for
an automatic transmission, or your vehicle can be
started in NEUTRAL (N) or any other gear as long as
the clutch is depressed for a manual transmission.
To restart when you are already moving, use
NEUTRAL (N) only.
The keyless access transmitter must be in the vehicle
for the ignition to work.Notice:Do not try to shift to PARK (P) if your
vehicle is moving. If you do, you could damage the
transmission. Shift to PARK (P) only when your
vehicle is stopped.
1. For an automatic transmission, with your foot on the
brake pedal, press the START button. For a manual
transmission, while pressing in the clutch, press
the START button. When the engine begins
cranking, let go of the button. The idle speed will go
down as your engine gets warm.
If the battery in the keyless access transmitter is
weak, the DIC will display FOB BATTERY
LOW. You can still drive the vehicle. See “Battery
Replacement” underKeyless Access System
Operation on page 2-5for more information.
2. If the engine does not start and no DIC message is
displayed, wait 15 seconds before trying again.
Notice:Your engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way the
engine operates. Before adding electrical equipment,
check with your dealer. If you do not, your engine
might not perform properly. Any resulting damage
would not be covered by your vehicle’s warranty.

Stopping Your Engine
If your vehicle has an automatic transmission, move the
shift lever to PARK (P) and press the ACC button. If
the shifter is not in PARK (P), the vehicle will go
into accessory mode and the DIC will display SHIFT TO
PARK. Once the shifter is moved to PARK (P), the
vehicle will turn off.
If your vehicle has a manual transmission, move the
shift lever to REVERSE (R) and press the ACC button.
If the shifter is not in REVERSE (R), the vehicle will
go into accessory mode and the DIC will display SHIFT
TO REVERSE. Once the shifter is moved to
REVERSE (R), the vehicle will turn off.
If the keyless access transmitter is not detected while
going to off, the DIC will display NO FOB – OFF
OR RUN?.
SeeDIC Warnings and Messages on page 3-54for
more information.
Notice:If you do not put a manual transmission in
REVERSE (R) before exiting your vehicle, your
vehicle will not be secured, the battery will drain
and could be damaged. Always put a manual
transmission in REVERSE (R) before shutting off the
engine and exiting the vehicle.
Racing or Other Competitive Driving
See your warranty book before using your vehicle for
racing or other competitive driving.
Notice:If you use your vehicle for racing or other
competitive driving, the engine may use more
oil than it would with normal use. Low oil levels can
damage the engine. Be sure to check the oil level
often during racing or other competitive driving and
keep the level at or near 1 quart (1 L) above the
upper mark that shows the proper operating range
on the engine oil dipstick. For information on
how to add oil, seeEngine Oil on page 5-13. After
the competitive driving, remove excess oil so
that the level on the dipstick is not above the upper
mark that shows the proper operating range.
Vehicles with the Z51 performance package have
greaseable outer ends on both of the rear toe-links.
Under normal use, lubrication should be performed as
described in the maintenance schedule. SeeScheduled
Maintenance on page 6-4andRecommended Fluids
and Lubricants on page 6-12. If you use the vehicle for
racing, lubrication should be performed at the end of
each racing day. See your dealer for lubrication
and make sure any needed repairs are made at once.
Proper procedures for performing these services can be
found in the service manual. SeeService Publications
Ordering Information on page 7-11.

Accessory Power Outlets
The accessory power outlet can be used to connect
electrical equipment such as a cellular phone or
CB radio.
The accessory power outlet is located inside the center
console storage compartment, on the forward left side.
To use the outlet, remove the tethered cap. When not
using it, always cover the outlet with the protective cap.
Notice:Leaving electrical equipment on for
extended periods will drain the battery. Always turn
off electrical equipment when not in use and do
not plug in equipment that exceeds the maximum
amperage rating.
Certain electrical accessories may not be compatible
with the accessory power outlet and could result
in blown vehicle or adapter fuses. If you experience a
problem, see your dealer for additional information
on accessory power outlets.Notice:Adding any electrical equipment to your
vehicle may damage it or keep other components
from working as they should. The repairs would not
be covered by your warranty. Do not use equipment
exceeding maximum amperage rating. Check
with your dealer before adding electrical equipment.
When adding electrical equipment, be sure to follow
the installation instructions included with the equipment.
We recommend that you see a quali ed technician or
your dealer for the proper installation of your equipment.
Notice:Improper use of the power outlet can
cause damage not covered by your warranty. Do not
hang any type of accessory or accessory bracket
from the plug because the power outlets are
designed for accessory power plugs only.
Electromagnetic Interference (EMI) can create a
disturbance and interfere with the keyless access
transmitter. EMI can be generated from devices such as
cell phones, cell phone chargers, or other items
plugged into the accessory outlet on the center console.

Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have or
may begin programs to inspect the emission control
equipment on your vehicle. Failure to pass this
inspection could prevent you from getting a vehicle
registration.
Here are some things you need to know to help your
vehicle pass an inspection:
Your vehicle will not pass this inspection if the Check
Engine light is on or not working properly.
To perform a Check Engine light bulb check with the
keyless ignition, make sure the transmitter fob is in the
passenger compartment. SeeIgnition Positions on
page 2-21. Press the bottom of the ACC button on the
instrument panel and hold the button down for ve
seconds. The instrument panel, including the Check
Engine light, will light up and the ignition will be on, but
the engine will not start — if you press the bottom of
the ACC button only brie y, less than ve seconds, the
accessory mode will be turned on, but not the ignition.
After the bulb check, be sure to press and release
the ACC button again to turn the ignition off and avoid
draining the vehicle’s battery.Your vehicle will not pass this inspection if the OBD
(on-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen if
you have recently replaced your battery or if your
battery has run down. The diagnostic system is
designed to evaluate critical emission control systems
during normal driving. This may take several days
of routine driving. If you have done this and your vehicle
still does not pass the inspection for lack of OBD
system readiness, your GM dealer can prepare the
vehicle for inspection.
