Safety Belt Use During Pregnancy
Safety belts work for everyone, including pregnant
women. Like all occupants, they are more likely
to be seriously injured if they do not wear
safety belts.
A pregnant woman should wear a lap-shoulder
belt, and the lap portion should be worn as low as
possible, below the rounding, throughout the
pregnancy.The best way to protect the fetus is to protect the
mother. When a safety belt is worn properly, it is
more likely that the fetus will not be hurt in a crash.
For pregnant women, as for anyone, the key to
making safety belts effective is wearing them
properly.
Right Front Passenger Position
To learn how to wear the right front passenger’s
safety belt properly, seeDriver Position on
page 22.
The right front passenger’s safety belt works the
same way as the driver’s safety belt — except
for one thing. If you ever pull the shoulder portion
of the belt out all the way, you will engage the
child restraint locking feature. If this happens, just
let the belt go back all the way and start again.
When the safety belt is not in use, slide the latch
plate up so that it is stored on the safety belt
stitching, near the guide loop.
If your vehicle has a center passenger position, be
sure to use the correct buckle when buckling your
lap-shoulder belt. If the latch plate will not go fully
into the buckle, see if you are using the buckle for
the center passenger position.

7. Push and pull the child restraint in different
directions to be sure it is secure.
8. If the airbag is off, the off indicator on the
instrument panel will be lit and stay lit
when the key is turned to RUN or START.
If a child restraint has been installed and the on
indicator is lit, turn the vehicle off. Remove the child
restraint from the vehicle and reinstall the child
restraint.
If, after reinstalling the child restraint and restarting
the vehicle, the on indicator is still lit, check to make
sure that the vehicle’s seatback is not pressing the
child restraint into the seat cushion. If this happens,
slightly recline the vehicle’s seatback and adjust the
seat cushion if possible. Also make sure the child
restraint is not trapped under the vehicle head
restraint. If this happens, adjust the head restraint.If the on indicator is still lit, secure the child in the
child restraint in a rear seat position in the vehicle
and check with your dealer.
To remove the child restraint, just unbuckle the
vehicle’s safety belt and let it go back all the way.
The safety belt will move freely again and be
ready to work for an adult or larger child
passenger.

In many crashes severe enough to inate an airbag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur
from the right front passenger airbag.
Airbags are designed to inate only once. After
airbags inate, 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 other parts that need to be replaced.
Your vehicle has a crash sensing and
diagnostic module which records information
after a crash. SeeVehicle Data Collection and
Event Data Recorders on page 489.
Let only qualied technicians work on the
airbag system. Improper service can mean that
your airbag system will not work properly. See
your dealer for service.
Passenger Sensing System
Your vehicle has a passenger sensing system. The
passenger airbag status indicator on the instrument
panel will be visible when you turn your ignition key
to RUN or START.
The passenger airbag
status indicator will
light ON and OFF for
several seconds as a
system check.
If you use remote start to start your vehicle from a
distance, if your vehicle has this feature, you may
not see the system check. When the system check
is complete, either the word ON or the word OFF
will be visible. SeePassenger Airbag Status
Indicator on page 183.
The passenger sensing system will turn off the
right front passenger’s frontal airbag under certain
conditions. The driver’s airbags are not part of
the passenger sensing system.

Remote Keyless Entry (RKE)
System
Your Remote Keyless Entry (RKE) system
operates on a radio frequency subject to Federal
Communications Commission (FCC) Rules
and with Industry Canada.
This device complies with Part 15 of the FCC
Rules. Operation is subject to the following
two conditions:
1. This device may not cause interference.
2. This device must accept any interference
received, including interference that may
cause undesired operation of the device.
This device complies with RSS-210 of Industry
Canada. Operation is subject to the following
two conditions:
1. This device may not cause interference.
2. This device must accept any interference
received, including interference that may
cause undesired operation of the device.Changes or modications to this system by other
than an authorized service facility could void
authorization to use this equipment.
At times you may notice a decrease in operating
range. This is normal for any RKE system. If
the transmitter does not work or if you have to
stand closer to your vehicle for the transmitter to
work, try this:
Check the distance. You may be too far from
your vehicle. You may need to stand closer
during rainy or snowy weather.
Check the location. Other vehicles or objects
may be blocking the signal. Take a few steps
to the left or right, hold the transmitter
higher, and try again.
Check to determine if battery replacement is
necessary. See “Battery Replacement”
underRemote Keyless Entry (RKE) System
Operation on page 90.
If you are still having trouble, see your dealer
or a qualied technician for service.

Remote Keyless Entry (RKE)
System Operation
The vehicle’s doors can be locked and unlocked,
and the trunk can be opened from about 3 feet
(1 m) up to 60 feet (18 m) away with the Remote
Keyless Entry (RKE) transmitter. If your vehicle
has the remote start feature, you can also start the
vehicle’s engine with the RKE transmitter.The following functions may be available with your
vehicle’s RKE system:/(Remote Vehicle Start):If your vehicle has
this feature, the engine may be started from
outside the vehicle using the RKE transmitter.
See “Remote Vehicle Start” at the end of
this section for more detailed information.
Q(Lock):Press the lock button to lock all the
doors. If enabled through the Driver Information
Center (DIC), the parking lamps may ash once to
indicate locking has occurred, or the horn may
chirp when the lock button is pressed again within
ve seconds from the previous press of the
lock button. See “FOB LOCK FEEDBACK” under
DIC Vehicle Personalization on page 229for
additional information. If the vehicle has the
content theft-deterrent system, pressing the lock
button may also arm it. SeeContent
Theft-Deterrent on page 104.
RKE with Remote StartRKE without Remote

"(Unlock):Press the unlock button to unlock the
driver’s door. If the button is pressed again
within ve seconds, all remaining doors will unlock.
The interior lamps will come on and stay on for
20 seconds or until the ignition is turned on.
If enabled through the DIC, the parking lamps can
be programmed to come on for a set amount of
time when the vehicle is unlocked using the
RKE transmitter. See “EXT (Exterior) LIGHT
DELAY” underDIC Vehicle Personalization on
page 229. If the vehicle has the content
theft-deterrent system, pressing the unlock button
on the RKE transmitter may disarm it. See
Content Theft-Deterrent on page 104.
V(Remote Trunk Release):Press and hold
this button for about one second to release
the trunk lid. The transaxle must be in PARK (P)
for this feature to operate.
L(Panic Alarm):Press this button to activate the
alarm. The ignition must be in OFF or
ACCESSORY for the alarm to work. When the
alarm button is pressed, the headlamps will ash
and the horn will sound repeatedly for two minutes.
The alarm will turn off when the ignition is moved to
RUN or the alarm button is pressed again.
Matching Transmitter(s) to Your
Vehicle
Each RKE transmitter is coded to prevent another
transmitter from unlocking your vehicle. If a
transmitter is lost or stolen, a replacement can be
purchased through your GM dealer. Remember
to bring any additional transmitters so they
can also be re-coded to match the new transmitter.
Once your dealer has coded the new transmitter,
the lost transmitter will not unlock your vehicle.
The vehicle can have a maximum of four
transmitters matched to it.
Battery Replacement
Under normal use, the battery in the RKE
transmitter should last about four years.
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.
The KEY FOB BATT LOW message in the
vehicle’s DIC will display if the RKE transmitter
battery is low.
