Enabling Keyless Unlocking:
With the vehicle off, press and hold
QandKon the RKE transmitter at
the same time for approximately
three seconds. The turn signal
lamps will flash twice quickly to

Passive Locking
The vehicle will lock several
seconds after all doors are closed if
the vehicle is off and at least one
RKE transmitter has been removed
or none remain in the interior.
If other electronic devices interfere
with the RKE transmitter signal, the
vehicle may not detect the RKE
transmitter inside the vehicle.
If passive locking is enabled, the
doors may lock with the RKE transmitter inside the vehicle. Do
not leave the RKE transmitter in an
unattended vehicle.
To customize the doors to
automatically lock when exiting the
vehicle, see
“Remote Lock, Unlock,
Start” under Vehicle Personalization
0 135.
Temporary Disable of Passive

When the vehicle is turned off and
an RKE transmitter is left in the
vehicle, the horn will chirp three
times after all doors are closed. To
turn on or off see Vehicle
Personalization 0135. Remote No Longer in Vehicle Alert
If the vehicle is on with a door open,
and then all doors are closed, the
vehicle will check for RKE
transmitters inside. If an RKE
transmitter is not detected, the
Driver Information Center (DIC) will
display NO REMOTE DETECTED
and the horn will chirp three times.
This occurs only once each time the
vehicle is driven.
Keyless Liftgate Opening
Press the touch pad on the liftgate
handle to open the liftgate if the
RKE transmitter is within 1 m (3 ft).
Key Access

To start the vehicle:
1. Place the transmitter in thetransmitter pocket, with the
buttons facing the front of the
vehicle.
2. With the vehicle in P (Park) or N (Neutral), press the brake
pedal and ENGINE
START/STOP.
Replace the transmitter battery
as soon as possible.
Battery Replacement
{Warning
Never allow children to play with
the RKE transmitter. The
transmitter contains a small
battery, which can be a choking
hazard. If swallowed, internal
burns can occur, resulting in
severe injury or death. Seek
medical attention immediately if a
battery is swallowed.
{Warning
To avoid personal injury, do not
touch metal surfaces on the RKE
transmitter when it has been
exposed to extreme heat. These
surfaces can be hot to the touch
at temperatures above 59 °C
(138 °F).
Caution
When replacing the battery, do
not touch any of the circuitry on
the transmitter. Static from your
body could damage the
transmitter.
Caution
Always replace the battery with
the correct type. Replacing the
battery with an incorrect type
could potentially create a risk of
battery explosion. Dispose of
used batteries according to
instructions and local laws. Do
not attempt to burn, crush, or cut
the used battery, and avoid
exposing the battery to
environments with extremely low
air pressures or high
temperatures.

The system has one or more RKE
transmitters matched to an
immobilizer control unit in the
vehicle. Only a correctly matched
RKE transmitter will start the
vehicle. If the transmitter is ever
damaged, the vehicle may not start.
When trying to start the vehicle, the
security light may come on briefly
when the ignition is turned on.
If the engine does not start and the
security light stays on, there is a
problem with the system. Turn the
ignition off and try again.
If the vehicle will not change ignition
modes, and the RKE transmitter
appears to be undamaged, try
another transmitter. Or, try placing
the transmitter into the transmitter
pocket located in the center
console. See Starting the Vehicle
With a Low Transmitter Battery
underRemote Keyless Entry (RKE)
System Operation 08. If the ignition mode will not change
with the other transmitter or with a
transmitter in the transmitter pocket,
your vehicle needs service. If the
ignition does change modes, the
first transmitter may be faulty. See
your dealer who can service the
theft-deterrent system and have a
new RKE transmitter programmed to
the vehicle.
It is possible for the immobilizer
system to learn new or replacement
RKE transmitters. Up to eight
transmitters can be programmed for
the vehicle. To program additional
transmitters, see Programming
Transmitters to the Vehicle under
Remote Keyless Entry (RKE)
System Operation
08.
Do not leave the transmitter or
device that disarms or deactivates
the theft-deterrent system in the
vehicle.Exterior Mirrors
Convex Mirrors
{Warning
A convex mirror can make things,
like other vehicles, look farther
away than they really are. If you
cut too sharply into the adjacent
lane, you could hit a vehicle that
is driving next to you. Check the
inside mirror or glance over your
shoulder before changing lanes.
The passenger side mirror is convex
shaped. A convex mirror's surface is
curved so more can be seen from
the driver seat.

Servicing the
Airbag-Equipped Vehicle
Airbags affect how the vehicle
should be serviced. There are parts
of the airbag system in several
places around the vehicle. Your
dealer and the service manual have
information about servicing the
vehicle and the airbag system. To
purchase a service manual, see
Publication Ordering Information
0415.
{Warning
For up to 10 seconds after the
vehicle is turned off and the
battery is disconnected, an airbag
can still inflate during improper
service. You can be injured if you

Warning (Continued)
are close to an airbag when it
inflates. Avoid yellow connectors.
They are probably part of the
airbag system. Be sure to follow
proper service procedures, and
make sure the person performing
work for you is qualified to do so.
Adding Equipment to the
Airbag-Equipped Vehicle
Adding accessories that change the
vehicle's frame, bumper system,
height, front end, or side sheet
metal may keep the airbag system
from working properly.
The operation of the airbag system
can also be affected by changing,
including improperly repairing or
replacing, any parts of the following:
.Airbag system, including airbag
modules, front or side impact
sensors, sensing and diagnostic
module, or airbag wiring .
Front seats, including stitching,
seams or zippers
. Seat belts
. Steering wheel, instrument
panel, overhead console, ceiling
trim, or pillar garnish trim
. Inner door seals, including
speakers
Your dealer and the service manual
have information about the location
of the airbag modules and sensors,
sensing and diagnostic module, and
airbag wiring along with the proper
replacement procedures.
In addition, the vehicle has a
passenger sensing system for the
front outboard passenger position,
which includes sensors that are part
of the passenger's seat. The
passenger sensing system may not
operate properly if the original seat
trim is replaced with non-GM
covers, upholstery, or trim, or with
GM covers, upholstery, or trim
designed for a different vehicle. Any
object, such as an aftermarket seat
heater or a comfort enhancing pad
or device, installed under or on top

away. SeeAirbag Readiness
Light 0113 for more information,
including important safety
information.
Charging System Light
The charging system light comes on
briefly when the ignition is turned
on, but the engine is not running, as
a check to show the light is working.
The light turns off when the engine
is started. If it does not, have the
vehicle serviced by your dealer.
If the light stays on, or comes on
while driving, there may be a
problem with the electrical charging
system. Have it checked by your
dealer. Driving while this light is on
could drain the battery. When this light comes on, the Driver
Information Center (DIC) also
displays a message.
If a short distance must be driven
with the light on, be sure to turn off
all accessories, such as the radio
and air conditioner.
Malfunction Indicator
Lamp (Check Engine
Light)
This light is part of the vehicle’s
emission control on-board
diagnostic system. If this light is on
while the engine is running, a
malfunction has been detected and
the vehicle may require service. The
light should come on to show that it
is working when the ignition is in
Service Mode. See
Ignition
Positions 0236.
Malfunctions are often indicated by
the system before any problem is
noticeable. Being aware of the light
and seeking service promptly when
it comes on may prevent damage.
Caution
If the vehicle is driven continually
with this light on, the emission
control system may not work as
well, the fuel economy may be
lower, and the vehicle may not
run smoothly. This could lead to
costly repairs that might not be
covered by the vehicle warranty.
Caution
Modifications to the engine,
transmission, exhaust, intake,
or fuel system, or the use of
replacement tires that do not
meet the original tire
specifications, can cause this light
to come on. This could lead to
